Plastic applications in the chemical industry

Environment and resources is the world's most compelling topics, scientific and rational use of limited resources is a fundamental protection.

Worldwide due to corrosion of materials, consume a lot of resources, resulting in huge losses to humans, hindering the development of productivity and leads to further deterioration of the global environment. According to some industrial countries, statistics, due to corrosion caused direct losses of GNP (GNP) of 2% to 4%, the most developed of the U.S. up to 4% or more. China every year due to corrosion caused direct economic losses of at least 200 billion yuan.

As an emerging class of plastic material, a relatively excellent chemical inertness and other good overall performance, has been in the field of anti-corrosion has been widely used. Plastic is an interdisciplinary corrosion, corrosion study and master the theory and application of plastic for further promote and expand the field of application of anti-corrosion plastic, save social wealth and resources have a very positive meaning.

1 Definition of plastic corrosion

Corrosion is a substance called environmental effects due to damage and deterioration caused by the phenomenon, the plastic sprayer in the chemical environment, the role of the media, its appearance, and mechanical damage caused performance degradation phenomenon, known as etching or chemical aging of plastic. Chemical aging is a form of plastic aging.

2 types of corrosion plastic

With the kind of plastic, chemical media, and environmental conditions, there may be different forms, varying degrees of chemical aging and erosion. Such as: Appearance (extinction, discoloration, wrinkling) changes, and mechanical properties (optical properties, electrical properties, weight) changes and chemical changes in structure and properties, study and master the plastics chemical aging of the law, can be more scientific and more reasonable used plastic, better use of plastics to solve corrosion problem.

Plastic corrosion basic reason for this is due to the chemical medium to penetrate inside the knapsack sprayer, diffusion to swelling, dissolution medium and the plastic cracking or chemical reaction, leading to a variety of corrosion phenomenon.

Plastic corrosion in general can be divided into: the primary valence bond within the polymer macromolecules damage secondary bonds between macromolecules damage. But usually these two types of composite damage and secondary bonds between macromolecules damage as much.

Classification of degradable plastics

Degradable plastics are a new type of plastic varieties, developed abroad can be degradable plastics began in the 1970s, which was mainly developed photodegradable plastics, aims to solve the plastic waste, especially disposable plastic packaging products, the environmental pollution problems , to the 1980s, research and development shift to biodegradable plastics based, and, while there have been no oil with renewable resources such as plant starch and cellulose, chitin and other animals as raw materials to produce bio-degradable plastics. In addition, the development of a microbial fermentation production of biodegradable plastics. portable sprayers A class of clinical applications can already living degradation of medical plastic, such as polylactic acid also attracted attention, hopes to use it to solve the plastic pollution problem, but, for this type of plastic is still classified as degradable plastics There are different opinions, Japan Degradable Plastics Council opinion that can not be classified degradable plastics. However, a new class of biodegradable plastic is plastic point of view, should also include a living body degradable plastics, and it might be from the use of biodegradable plastics will be classified into the environment (natural) and bio-degradable plastics (Environment) degradable plastics. The latter has been used in the medical surgical sutures, artificial bones.
Chinese basic research and development of degradable plastics with the world. However, the Chinese degradable plastics research and development began agricultural mulch film. China is a large agricultural country, mulch consumption accounts first in the world to solve the accumulated residue mulch on farmland on the harm caused by plant root growth and affect crop yields,trigger sprayer as well as plastic film for agricultural tractor problems hinder the operation of the 1970s that began the development of photodegradable plastic film before and after 1990, there has been filled in the General Plastics starch biodegradable plastics, while the light degradable plastics based on starch filled simultaneously develop both photodegradation and biodegradation feature film . Currently various types of degradable plastic film being developed, the application is still in the demonstration phase. In recent years, as China's living standards improve, disposable plastic packaging products bring increasingly serious environmental pollution problems, therefore, are also being actively developed for packaging, mainly disposable packaging biodegradable plastic products, such as garbage bags, shopping bags, lunch boxes, etc..

The principle and construction of electric sprayer

How to make electric pressure sprayers  operating principles and structure by which parts components has been a part of people's questions concern the electric sprayer. This article briefly discusses electric sprayer under the working principle and structure.
Electric liquid sprayer  liquid from the storage barrels through the filter, coupling head, suction, connecting tubes, nozzles, nozzle connected in turn communicates composition, suction is a small electric pump which is electrically via electrical connection with the battery and switch, battery box mounted on top of the liquid storage drum, liquid sink barrel can be formed with the loading of the battery recess, of lines of the electric point of blooming due to the cancellation of the suction suction tube, thus effectively eliminating the pesticide outside the filter Damage operator's ills, and effort, and the electric pump pressure than people manually suction tube pressure, increasing the spray distance and range.

Diluted spray pesticides need to pay attention

Many friends of farmers prepared in an electric sprayer tank dilution with directly after spraying. However, due to the technical preparation of the herbicide master well diluent, in the preparation process tends to occur, which directly affect the herbicidal effect. In order to improve the control effect of herbicides in the dispensing process must pay attention to the following four questions:
1. Herbicide formulations: herbicide formulations there are many different forms of preparation in different ways. Such as emulsions, liquid and gel suspension agent will quickly dissolve after water and spread of these formulations can be further dilution method herbicide formulated about a certain amount of herbicide directly into electric nebulizer dilute good immediately after spraying. 72% Doyle emulsion, 90% Wo Nice EC can use this method. Wettable powders, dry suspension emulsion and other formulations step dilution method can not be used, but must be prepared using the two-step dilution method: The first step is accurately weighed on demand herbicides, add a little water stir, it is fully dissolved liquor. The second step is to add a certain amount of mother liquor certain amount of water, diluted to garden pressure sprayers evenly. 75% superstar hanging drying emulsion, 25% WP nitrofen and so must be diluted using this method, and must not be a one-step dilution dilution.
2. Preparation Diluent: electric sprayer kits in preparation diluent, you must first kits add about 10 cm deep water only after the mother liquor was added slowly to the pharmacy or medicine cabinet, and then add water to the water line can be sprayed. Never add water in the water tank before or will not fill with water and pour it into the tank agents or liquor, because it is difficult to prepare a homogeneous diluent, will seriously affect the control effect.
3. Medicine cabinet with a good liquid immediately after spraying, because the proportion of various herbicides and not exactly the same proportion of water, such as herbicides gravity than water, after a period of storage herbicide will sink, resulting in lower drug solution concentration, the upper liquid concentration is small, seriously affecting the herbicidal effect.
4. Electric sprayer in the backpack sprayer  ilution was added to the water line as well, must not be filled at once. If the nebulizer kits filled in application personnel of the liquid medicine chest when walking is difficult to shake, Pharmacy prone to sinking or floating phenomenon, affecting the uniformity of the liquid, thus affecting the herbicidal effect. In addition, the application personnel also easy when spraying liquid spilled out from the medicine chest catchy, drip application personnel to the body, so the medicine cabinet in the liquid must not overfill.

Sprayer to spray pesticides skills

Electric sprayer before and after use be sure to make the appropriate checks in the process of spraying pesticides should follow certain precautions.
Electric sprayer before the job is to check all parts for damage, without leakage, spray is normal, the first trial with water garden sprayer backpack.
Spraying pesticides, the operator should stand upwind, and pay attention to changes in wind direction, way of walking time to change jobs, try to forward interlaced spraying.
Knapsack power sprayer tank can not be overfilled to avoid bending when the liquid from the medicine chest mouth overflow spilled into the spraying people. Select the correct application time should avoid spraying at noon when the sun is strong, because when pesticides, volatile, and the operator sweating, pesticides easily into the body through the pores.
Electric spray apparatus in the event of failure during operation, should immediately stop work, close the valve, inspect repairs. If it is electric tree sprayers pipe or pump failure, you must first reduce the pressure in the pipeline. Open the pressure in the gas tank, you should first release the compressed air cylinder, to prevent accidents.
After each use, the barrel should be promptly poured the remaining liquid, and washed with water poured dry.

In recent years, the spray volume (L / ha) a reduction in the sprayer Saikawa smaller diameter of the nozzle orifice, the filter aperture becomes smaller accordingly, (changed from 50 to 80 months, or 100 mesh), in order to ensure such a small strainer holes are not clogged liquid in the text, and some sprayer _L A device equipped with self-cleaning unit over, · Use high-pressure liquid from the pump to provide dynamic scour white filter screens, The debris flow by the return line back to the tank directly. Motorized sprayer tank with liquid mixing device to ensure that the concentration of the liquid inside the spraying process has always been consistent. Most pump sprayers equipped with hydraulic mixing method are used, to ensure the stirring effect, m mixed use with the flow amount of liquid (L plus in) should be at least 5% of the tank volume, and should certain Osteoform. To this end, in addition to the main part of the supply pressure of the liquid spray gun, the part of the reflux tank used for mixing.

Pump with rotary pumps and pump two types of living complex. Rotary pump with roller pumps and centrifugal pumps, only use sprayer. Reciprocating pumps piston pumps, piston pumps, diaphragm pumps, etc., in a motor and manual spray jp14, used widely on. With reciprocating pump sprayer is equipped with inlet and drain valves and air chambers, sprayer equipped force on the liquid supply pump [such as reciprocating pumps and roller pumps) and the two devices must be equipped with a safety valve in the spray Shi excess liquid tank when returned. protection spray pressure system. Adjust spring acting on the pressure relief valve on the spray available in different R force. manual sprayer

Hydraulic sprayer spray nozzle is a key component of the liquid. According to different-shaped spray mist, fog nozzles are tapered and scalloped penetration nozzle two kinds.

Making sprayer

Sprayers many forms, but the core principle of the structure is basically the same. Nebulizer is used to disperse the particles in liquid instruments, electric sprayer in the laboratory and medical work are widely used production process is simple now specifically described as follows: farm sprayer

(1) outlet diameter: jet outlet tube diameter should generally be greater than the inner diameter of the pipette exports doubled appropriate. For example: suction outlet tube diameter 0.5 mm, jet outlet tube diameter is I mm, should be at the head of the pipette Ling gas outlet center distance between the phenomenon can not have a skew, skew will affect Ling fog.

(2) Production of the core: 6-21 press (1) is made in the form of the core, to ensure that the suction and injection tube aperture and using a small glass rod and the two-phase solid stick, the end of the jet tube Yan a bell for the next process welding.

First the upper and lower ground cover processing is completed (refer to Chapter ways round mouth and with plug), taking the tube length required by firing a round bottom, shown in Figure 6-23 (a), part preparation is ready, draw tube tilt Align the bottom center of the flame regiment, a small mill covered over flat rotation, when the two pillow melting material, the small grinding head over to the round-bottomed Center For dry mouth, slightly pull away from the fire, and then first in the big mouth slightly out of Jane blowing, then the little mill for blowing the cover, rotate burn sandwich joint, should focus on the right hand side of the joint burned over on (to avoid round bottom deformation). To make sandwich bottom flat, both sides must be blowing. Welding and burning holes open siphon bend, shown in Figure 6-23 (2). Put to the flame tip annealing some (not sloppy, the following can not be annealed, but other joints sealing, the flame must not involve the mezzanine connector), near the center of the burn out of bent siphon tube, shown in Figure 6-23 ( 3), burning materials should not be too Ye, bent over quickly when grinding mouth on the big blow to cool (do not rush out of the siphon tube near the centralizer, prisoners out of the bobbin body is cold, such as hot glass touch rearward easy burst). Extraction tube next to the tube after completion of the sealing bends, joints with a small flame can turn annealing number, followed by a slight burning flame aces siphon ring outside, its centralizer, close to the body out of the bobbin, see Figure 6-23 ( 4),

(3) connection: will be ready to slug into the jacket tube, two pillow melting brushed respectively, shown in Figure 6-21 (2). In sub-side end silk pillow melting shrink thick, burning blown ellipsoidal, shown in Figure 6-21 (3). Left-handed tilt, then with a small flame burning in the core, and then pull in addition to more than expected, opening sealing takeover, see Figure 6-21 (4). Annealing while, after cooling the flame burning with a large flat curved outer tube spout site, see Figure 6-21 (5). After cooling explosion unless I expected, left hand grip receivership, with a large flame pillow melting in the mouth evenly, remove from heat immediately into the light work clamp, loosen the sheets into a flat mouth, shown in Figure 6-21 (6), Figure 6-22 (1-4) is one of several better performance of the sprayer. plastic sprayer

Precautions pedal sprayer

Pedal sprayer is a high injection pressure, long range of manual sprayers. Operator to foot dock, he pushed the joystick back and forth, driven reciprocating piston pump, the liquid suction pump, and pressed into the air chamber, the formation of 0.8-1.0 MPa pressure, you can carry out normal spray . Pedal sprayer applies to fruit trees, gardens, sheds and other vine plants, pest and disease control, can also be used for storage pest and building gunite, decorative wall and so on. Use Precautions: garden sprayers

1, the liquid must be filtered to prevent nozzle clogging impurities affect the spray quality.

2, the spray pressure gauge and a safety device is not installed, the use of the feel of the estimated size of the pressure to normal spraying is appropriate.

3, water flooded into the liquid inside the seat must avoid traps.

4, when spraying stops, you must immediately turn off the switch, stop pushing the joystick.

5, not both at the same joystick to avoid overloading the work leaving the hose rupture and damage equipment. knapsack sprayer

Knapsack sprayer should also focus attention to the following

① sprayer new leather should be immersed in a bowl before installing oil or animal oil (avoid using vegetable oil), soaked for 24 hours. Install the pump cylinder piston rod assembly, should pay attention to the leather side of the bowl ramp on the pump cylinder, then rotate it, the piston rod vertically, with the other hand to help push the edge of the cup into the pump cylinder, can be successfully loaded, avoid hard-line stuffed. knapsack sprayer

② According to the need to use the appropriate lance and nozzle. NS-15-type sprayer lance several double nozzle spray bar and four T-shaped spray nozzle straight rod for wide full spray, U-shaped double nozzle spray bar can be used to spray the crop rows, side double nozzle spray bar For the base between the lines on both sides of the crop spraying. There are several hollow cone nozzle fog nozzle aperture piece. Flow macropores. Fog spray bar for wide full spray, U-shaped double nozzle spray bar can be used to spray the crop rows, side double nozzle spray bar for the base between the lines on both sides of the crop spraying. There are several hollow cone nozzle fog nozzle aperture piece. Flow macropores. Coarse droplet, spray angle is relatively large; holes Instead, the traffic is small, fine droplet spray angle is small. According to the requirements of the spray operations and crop selection of appropriate size.

③ the spray bar mounted spray T-straight slit nozzle 110 °, the nozzle slots on the spray bar to be slightly deflected about a 5 ° angle of the axis, so that the mist can flow adjacent the nozzle and do not impact. Job is to pay attention to control the height of the boom, so that each stream fog nozzle overlap, the entire amount of spray mist evenly distributed within the web for spraying herbicides in full use.

④ bear when working every minute pushed the joystick 18-25 times. Operated sprayer must not excessively bent to prevent liquid overflow from the lid at splashed on him.

⑤ filling liquid, must not exceed the water line as shown on the tank wall. If overfilled, the work will occur at the cover of the pump barrel spill phenomenon. The liquid air chamber exceeds a safe level line, should immediately stop cheer, to avoid air chamber explosion. pressure water sprayer

⑥ all leather washers, immersion foot oil storage should avoid shrinkage sclerosis.

⑦ end use every day, you should add a little water jetting and cleaning spray ministries, and then placed in dry indoor air.

⑧ spraying of herbicides, it must be sprayers, including the tank, hose, lance, nozzles, etc. thoroughly cleaned so that the next time when other pesticides sprayed on crops produce injury.
