Silicon carbide in the glass industry applications

A cooling section and all of paragraph
It is composed of two identical heating element with three cold end is welded using a special process, namely two indirect heating element in a cold end, the total length of the three corresponding channel width and material (in the import of the material Road dual threaded silicon carbide) Since the middle of silicon carbide less heat and no heat or heat near the side wall parts, coupled with reasonable design, we can ensure the flow of molten glass at uniform temperature drop. When the feed channel design, etc.fruit tree sprayer Some manufacturers also use the diameter silicon carbide (ie, three type silicon carbide), which is composed of a heating element and two cold ends welded together. Glass liquid flowing through the cooling and homogenization segment of the process, should be made uniform cooling of the molten glass to a temperature suitable for molding, if no measures are taken, Forehearth more heat on both sides, the middle parts of the less heat will cause the glass to the middle part and both sides of the larger temperature gradient, the temperature of the glass was the same uniform cross-section, the glass viscosity is inconsistent, directly affect the quality of the molding, the feed temperature to the same, while the cooling holes in the cooling section aside, by adjusting the cooling holes the opening degree of the cooling section to adjust the middle of the forehearth much heat, the temperature uniformity; other hand, the use of special silicon carbide auxiliary heating to achieve. Silicon carbide are generally evenly arranged inside the feed channel above the molten glass, the glass was kept a certain distance downwards radiant heating. Road on both sides in order to ensure material is not heated by heating the middle part, generally used in the glass industry-specific silicon carbide Forehearth five rods (ie dual silicon carbide heating element).
Whether used three rods or five rods, homogenizing effect by feeding channel structure and silicon carbide heating to decide, while Forehearth ultimately how much each segment by the control system to control the temperature. Forehearth use three silicon carbide silicon carbide on both sides of the glass wall of liquid heating also heated,household sprayer so to ensure that each segment forehearths temperature, can also play on the sidewall cooling complementary role, but nowhere near the homogenizing effect five silicon carbide
Glass flow through all of paragraph later, the temperature dropped to a proper value even if the temperature at the right spout not controlled, is still difficult to ensure there is a constant gobs uniform temperature, so temperature is too high or too low will affect the gob shape, and ultimately affect the quality of the glass container forming.

Characteristics of silicon carbide and maintenance

Silicon carbide is silicon carbide as the main raw material of high temperature heating element. Synthesized in the late 1800s after silicon carbide, silicon carbide in 1905 by the German legal system into a synthetic silicon carbide industrial value, brand name called "Xi Lite" (Silit).

Country in 1957 successfully developed silicon carbide, and conduct industrial mass production. Silicon carbide is a high-purity green silicon carbide, carbon, silicide recrystallization at high temperature electric heating elements made of high temperature, the silicon carbide content of 98%,chemical sprayer so that the silicon carbide having substantially the same physical and chemical properties. Compared with other metal heating element, it has the following unique advantages: strong acid, strong antioxidant capacity; surface load density than the metal heating elements, heating quickly, high thermal efficiency; resistance to rapid thermal quench resistance, linear expansion coefficient; high thermal conductivity; use of high temperature, long life, normal air atmosphere, rod surface temperature up to 1600 ℃, continuous service life of up to more than 2000h. Install, easy to replace; wide source material. Their classification, the resistance value adjustment similar mounted on the same area, so close to the power supply. To test each silicon carbide heating element is good work, power clamp meter tests available individually measured current. In the same area a voltage equal to the current requirements under similar deviation does not exceed 10%, if the individual current is too small to explain the resistance. If the current is too small, not too much resistance is poor contact pin press. If there is no current may be silicon carbide heating element has been broken, should further examine the replacement.weed sprayer Carbide heating element brittle and easily broken, especially in the most vulnerable position with thread, the installation should be especially careful, gently, the installation should pay particular attention to not allow unilateral force, if necessary, apply heat-resistant silicon carbide steel trap Gently push and pull rod steel sleeve, the placement of sheath fixed. Silicon carbide heating element after a certain time, since the resistance value increases, the need to raise the voltage to compensate for the loss of resistance is increased and therefore require a certain voltage transformer adjustment range; For continuous operation of the furnace and forehearth voltage adjustment range of 0.7 ~ 2.5V (V is the initial use of silicon carbide components voltage). Supercharging regulation, can extend the life of the silicon carbide component.

Spiral nozzle cooling tower applications

The working principle of the cooling tower heat when cooling water entrained in the column and exposed to air, due to the existence of temperature, cooling water and air direct heat, and because the surface and the vapor pressure difference between the air in the pressure under the effect of evaporation of the water heat away, so that heat transfer to the air and scattered into the atmosphere, so as to achieve the purpose of cooling, water distribution is a key part of the cooling tower, whose role is evenly distributed into the water filler on contact with water vapor interface increases, the cooling effect of the cooling tower greatly, so the cooling water is uniform Tabb cooling water temperature is critical to reduce, but also the cooling tower design and application of the first issues to be considered
Cooling tower and cloth bearing damage occurs frequently clogged plumbing failures, mainly due to the following factors, namely water vapor entering the bearing, the bearing internal oil emulsion deterioration failure, resulting in bearing damage caused by water distributor does not rotate; Second cycle cooling unclean water, there are many entrained debris, because the circulating water pipe line is not installed water filters and water distributor smaller diameter, debris easily block the cooling water at the blowhole Tabb
To prevent these failures, guaranteed fixed water power sprayer distribution effect, cloth hose nozzles installed to improve the spray area, you can use spiral nozzle, spiral nozzle specifically the following characteristics:
One, one-piece design, no internal vane
2, high efficiency, the injection speed and the injection angle of 50 degrees to 180 degrees
3, good atomization, portable sprayers conical, and have anti-clogging performance
4, the inner (outer) threaded connection for easy cleaning and maintenance
Spiral nozzle nozzle is one of many most distinctive kind of liquid through the continuous spiral smaller body tangent and after the collision, into a small droplet ejection, and in the nozzle chamber, the flow from the inlet to the outlet channel design, without any obstacle deflector blades and, at the same flow conditions, the maximum free diameter of the spiral nozzle is more than 2 times the conventional nozzle, to the greatest degree of reduction of the occurrence of congestion
Since the cooling medium is water, the cooling effect of the cooling tower, the cooling effect of the spray shape of the water in the circulating pump operating conditions in certain circumstances, the circulating water in the cooling tower and the impact pressure must, therefore, in the choice of nozzle type When important consideration
1, in order to improve the circulating water in the cooling tower of the distribution area of ​​the nozzle spray angle and spray pattern
2, according to the circulating pump flow to select the desired nozzle injection quantity, determine the number of nozzles, but if too many, not easy to install and maintain
So select the number of nozzles, in principle, be less in quantity, water should be uniform, in order to ensure the cooling water in the cooling tower distribution effect, select the spray angle of 150 degrees, the spray pattern is solid cone nozzle, in order to facilitate the installation, you can save installation costs, and to facilitate future maintenance, so to minimize the number of nozzles

Season farm maintenance needs attention

Fall harvest has been completed, farm storage should be timely maintenance in order to keep it in good technical condition and prolong life, we must do a good job, "seven defense",portable power sprayer  namely:
Corrosion: Corrosion damage not only metals, but also to other metals have great damage effects, causing corrosion of the water causes corrosion and oxidation chemical action of acids. Prevent corrosion of ways, first make farm machinery to keep dry; two acids is carried out exclusively custody; or agricultural smear acid substances to protect them.
Rust: Severe corrosion will destroy the strength of parts, causing a loss of performance. Mainly due to corrosion caused by water and metal oxidation. To prevent the metal does not rust on the metal surface to be coated with anti-embroidered agent. Short-term storage of waste oil can also be applied rust.
Fire. Flammable materials warehouse or storage space to keep away from ignition sources, and should have fire extinguishers, sand, water tanks and other fire-fighting equipment.
Anti-moisture. Wet corrosion prone metal and other materials corrosion, electrical equipment, particularly large role in the loss. Therefore, the metal parts, materials and generators, motors and other electrical equipment to be placed in indoor storage,manual sprayer to keep dry and ventilated to prevent moisture.
Anti-deformation. For easy bending wood pieces, bumper parts, etc., use shelf stable support pad, avoid sun exposure; pair of variable load or gravity bending deformation of parts required to produce a reasonable place.
Anti-cracking. Cold season, low temperatures, cooling water and other liquids present in the body is easy to freeze, resulting in volume expansion, cracking components. Thus, after the job should be put to the service of the engine cooling water.
Against loss and theft. Farm machinery or spare parts for safekeeping and necessary tools to do ground inspection, ground cleaning, ground maintenance, ground inventory. In addition, good security work equipment, to prevent others from theft and vandalism.

Expert guidance purchase and use of pesticides

Pesticides are an important agricultural production, in food production, the effective supply of agricultural products and farmers, plays an irreplaceable role. Therefore, how scientific and rational selection and use of pesticides are friends of farmers must be one of the knowledge,agricultural sprayer which can be effective in preventing the proliferation of fake pesticides, reduce unnecessary losses, to increase production purposes.
Scientific buy pesticides
Purchase of pesticides, should carefully read the pesticide label, according to "product knowledge, symptomatic medicine" principle, a reasonable choice of pesticides.
1, see Name: July 1, 2008, the pesticide product name is no longer used only to simplify common name or common name. Particular attention to look at the label on the pesticide label under the name of a valid name, the content and the formulation is clear.
2, see the "three cards" sign: Refers to pesticide registration number, product standards, production approved No. Direct sales of imported pesticides Pesticide Registration Certificate only one card number.
3, see the scope of use: First,backpack chemical sprayers you need to select based on prevention and on the label of the control object for the same crops and pesticides. The second is marked by pesticide application to verify whether the method appropriate for your use. Third, when there are several products are available, give priority to select the less, low toxicity, residual small, safe and good products.
4, see net content, production date and duration: Pesticide production date shall be indicated on the label and batch number; validity; product weight (net weight).
5, see the product appearance and labeling:
First, observe the product's appearance. Two is to observe the appearance of the product packaging and labels. Three is to observe whether the contents of the label is complete.

Overview of degradable plastics

Refers to a class of biodegradable plastic and its products can meet the performance requirements, while preserving performance of the same period, while in the natural environment after use conditions can degrade pairs environmentally friendly plastic material, so it is also referred to degradable plastics.
Polymer degradation is the result of chemical and physical factors polymeric macromolecules ingot fracture process. Polymer exposed to oxygen, water, heat light, rays, chemicals, pollutants, mechanical force. Insects, animals, and microorganisms and other environmental conditions, degradation of macromolecules strand breaks is known as environmental degradation. Degradation of the polymer molecular weight decreases, the polymer material properties is reduced until the polymer material of the loss can be used,hand sprayer  this phenomenon is also known as the aging degradation of the polymer material.
Both natural polymers and synthetic polymers are exposed to degradation under environmental conditions, but, in the same environmental conditions, a variety of polymers, in particular the sensitivity degradation of different synthetic polymers, and thus, various polymers solvability also vary, for example, polypropylene photooxidation easily degraded environmental conditions, and polystyrene in the same environmental conditions difficult to degrade, polyvinyl alcohol in the presence of certain microorganisms are easier to degradation of environmental conditions , while polyethylene, polypropylene, polystyrene difficult conditions in the same environment degradation.
Environmental degradation of biodegradable plastics mainly related to biodegradation, light and chemical degradation, and that the three main degradation processes mutual synergistic,liquid sprayer collaborative and coherent action. For example, photodegradation often simultaneously with the oxide degradation and promote each other; biodegradation more susceptible to degradation after the light.
The polymer degradation and aging stability of the polymer is directly related. Aging degradation of the polymer plastic shortening life. Therefore, since the inception of plastic, scientists working on the aging of these materials, namely stabilization studies to obtain high stability of the polymer material, and the current national scientists are using the aging degradation of the polymer Behavior racing to develop degradable plastics.

China's agricultural machinery maintenance industry several weaknesses

First, the technology is weak
According to the survey, the current agricultural machinery maintenance workers mainly consists of the following parts: The first part is the Chinese tradition "apprentice chef" mode under the old master, older man; second part is the "main force", around the age of 35, mostly from the colleges or related technical school graduates, there is a vigorous agricultural industry is the backbone; third part is an apprentice, laid-off workers, migrant workers, etc., generally low level of education. The composition of these categories of employees ratio of roughly 3:5:2.
Second, poor equipment maintenance
Some maintenance space is the extension of the previous old-fashioned individual workshops; electric hand pressure sprayer hire some temporary dressing room. Urbanization development, the Government land planning and adjustment, resulting in some maintenance depot, getting smaller and smaller venues.
In the county agricultural industry, on the part of businesses and agricultural machinery repair parts sales point, the vehicle detection and diagnosis of major asset is the experience of old or outdated equipment to determine, for the decoder, exhaust gas analyzers and other technical equipment scanty, as furnishings, rarely used; electric sprayer and some companies did not buy such equipment; there are some parts repair business and agricultural point of sale equipment, although increasing every year and update, but the speed is far behind the pace of social development and models change speed.
Third, the management system obsolete
Part of the maintenance business and agricultural machinery spare parts sales points not announced fixed working hours, fees, electric weed killer sprayer work unit price, or on the wall of the published fixed working hours, fees, hours price unchanged for years. "Quality assurance of the system", "certificate of completion and maintenance of the system", "equipment management system", "responsibility for production safety management system," and so there can be no executed. Many companies there are multiple charges, arbitrary charges, do not use uniform provisions competent industry documents, bills, accounting, and maintenance of consumers are not signed maintenance contract required.

Spray cleaning methods and benefits

Spraying two kinds of pesticides can not or should not be mixed before the back sprayers must be clean, otherwise, not only will reduce the efficacy and prone to injury, resulting in undue loss. The specific cleaning method is:
1, plastic bucket sprayer
Pour 5% of the hot alkaline (temperature above 60 ℃), so full lance, nozzle and other parts, shake once every 10 minutes, after 2 to 3 hours, pour the lye, then water Rinse 2 to 4 times.
2, drum sprayer
Pour 1% of black alum water (ie, ferrous sulfate solution) for 2 hours, then rinse 2-4 times; also can be washed with hot alkaline soak (as above) for 1 hour, then hot alkaline wash again, and finally rinse with water 4 to 5 times.
In addition, the spraying of herbicides used in electric weed sprayer  general cleaning effect is not good, will bring a chronic injury to crops, affecting crop growth as well as the final production. So you want to set up dedicated sprayer spraying of herbicides.

Everything has to be cleaned after use sprayer

Electric bottle plastic sprayer spray finished cleaning immediately after drug treatment, particularly the use of highly toxic pesticides and various herbicides, the more you want to immediately Yaoxie barrel clean, otherwise it will produce crops or vegetable poison. Herbicide treatment leaves the plant, there are governance broadleaf plants, contraceptives during use if not cleaned, can easily harm alternately with different types of plants. Therefore, the electric sprayer after use cleaning sloppy.
Specific cleaning method description:
1, herbicides
(1) clean water:
Common wheat herbicides such as superstar (tribenuron), corn herbicides such as B A mixture of soybean, peanut field herbicides such as haloxyfop, rice fields in addition to agents such as God, hoe, bentazon, etc., after the kick , to be immediately cleaned with water buckets and various parts several times, and later will be filled with water foam sprayer soak 2-24 hours, then wash 2-3 times, you can rest assured that use.
(2) mud cleaning:
For g king track (commonly known as the light swept away) in case of soil can be passivated, loss of herbicide active principle, and thus kick herbicide Gramoxone, just wash immediately with mud and water will spray a few times, and then washed with water that is available.
(3) ferrous sulfate wash:
Herbicides, only 2,4-D butyl ester hardest to clean. After spraying the herbicide in after ferrous sulfate solution required 0.5 full wash.
2, pesticides
(A) general use of pesticides after repeated washing with water, upside down to dry.
(2) the toxicity of the pesticide, with the mud used after repeated washing, dry upside down.

Electric sprayer troubleshooting methods

Electric back sprayers  with a compact and flexible, easy to use, ergonomic advantages, more and more farmers and friends favorite to become the main tool for spraying. However, because many farmers friends did not master the correct way to use electric sprayer frequent cause various problems. So, electric sprayer out of trouble how to solve?

1, spraying handle switch at the water leakage. Switch asbestos gasket wear or abrasion may cause the switch switch leakage, this phenomenon occurs, it should be replaced with new washers or asbestos. The leak was due to skin damage or gasket sealing off the gas chamber, and therefore timely for welding.

2, do not play into the gas chamber, the electric joystick under pressure does not focus. This is because the hardening shrinkage or cracking spray cup, the cup bottom of the nut loosening caused. Cup should be little pressure to open or replace it with new cups, immersed in oil or lubricating oil, lubricating installed after expansion, coated with a little oil, and tighten the bottom nut.

3, electric flower sprayer out of the fog-performing, easy drip. This is because the spray nozzle clogging, the filter casing valve is blocked or out of the water contamination caused by other reasons put live. Should clear the nozzle to remove debris; open the casing if the casing should be cleaned clogged strainer, check valve, remove dirt.

How to improve the quality of agricultural products exist

1, improve the quality and technical level of consciousness.
① strengthen leadership and staff to the quality of survival of the concept of consciousness.
Now increasingly fierce competition between the industry, China's industrial production levels from the world's advanced countries there is a gap, as business leaders when there is a sense of crisis and urgency, and the company's future sense of urgency. portable sprayers
② strengthen staff training and quality consciousness.
The gradual establishment of enterprises to raise awareness of workers and technical qualities mainly to administrative and financial penalties as a means to a quantitative quality indicators, establish a strict, complete and practical rules and regulations, to avoid substandard products factory, established in employees quality of survival of consciousness.
2, to strengthen the control of production processes.
① to strengthen inspection of raw materials into the plant.
The manufacturers with the necessary testing equipment, raw materials for the purchase of a variety of serious testing, strict feeding off, to ensure the quality of raw materials, right now there is no testing equipment and check the capacity of enterprises, the feed requirements of each supplier provide material report card, strictly control the quality of raw materials, from the source control product quality.
② to improve the level of technology.
Enterprises in the production process to detect repeated trial and error experience, testing departments and technical departments to communicate with each other, warranty service department to provide users with the process of quality problems, summed up the law, to ensure product quality and stability, and to the brothers and manufacturers and professional scientific research departments to learn from the theory and practice to improve the technical level of production operators, while taking new technology to improve product quality.
③ increase the necessary processing and testing equipment.
Equipment, precision direct impact on product quality, such as the acquisition of more advanced CNC lathes, improve product quality; detection equipment can detect product quality and performance, in order to improve product quality to provide an improved basis. manual sprayer

Why should wash sprayer

Before professional backpack sprayer of pesticides can not or should not mix the two, you must clean the sprayer, otherwise, not only will reduce the efficacy and prone to injury, resulting in undue loss. The specific cleaning method is:
1, plastic bucket sprayer
5% of the first pour hot lye (water temperature above 60 ℃), so full of all parts of the lance, nozzles, etc., shaking once every 10 minutes, after 2 to 3 hours, pour the lye, then water rinse 2-4 times.
2, drum sprayer
First pour 1% black alum water (ie, ferrous sulfate solution) to soak 2 hours, then rinse 2-4 times; may also be soaked with hot alkaline (as above) for 1 hour, then hot alkaline wash again, and finally rinse with water 4 to 5 times.
In addition, the spraying of herbicides used in electric sprayer, general cleaning ineffective, will bring chronic injury to crops, growth and even the final crop yield. So you want to set up a dedicated spray herbicide sprayer.
