At present, biological pesticides suitable for vegetables mainly include Bt emulsion, Aweiduqing, Caifengning, Nongkang 120, HD-1, agricultural streptomycin, and Tianli. Acrylic Plastic,also call the Polymethyl, Polymethyl methacrylate is a popular name, abbreviated as PMMA.
Translucent plexiglass similar to frosted glass, reflect soft, use it to make handicraft, make person feels comfortable and easy.
Burning Features: the combustion characteristics, flame retardant, Acrylic Plastic/PMMA can continue to burn after the fire, flame bottom is blue, the top is yellow, the top is white softening foaming during burning, the smell of flowers and decay at the same time gives us.

1. Vigorous application of bio-pesticide Bio-pesticide is a pollution-free pesticide after application on vegetables without pollution or residue. For example, using 100-150g Bt emulsion per acre and spraying 50kg of water can effectively control pests such as cabbage caterpillar, diamondback moth, and yellow guarded melon. With 2% agricultural anti-120 water agent 150-200 times liquid, it can prevent melon powdery mildew and leaf spot disease. With 72% agricultural streptomycin 3000-4000 times liquid, it can effectively prevent cabbage, celery soft rot, cucumber bacterial angular leaf spot and so on.
2. Reasonable application of chemical pesticides First, it is prohibited to use high-toxic and high-residue pesticides in vegetable production, such as methamidophos, isocarbophos, carbofuran, 1605, monocrotophos, omethoate, dicofol, iron gram. Second, the symptomatic selection of high-efficiency, low-toxic, low-residue pesticides, such as crystal trichlorfon, phlegm, puffer, virus A, chlorothalonil, keering, carbendazim, phytopath, fast Third, it is to strictly control the concentration of the liquid, the amount of drug per acre and the number of times of application; the fourth is to accurately grasp the safe interval of harvesting, the interval between the last dose and the harvest should be 10-15 days. Above, to ensure the standard of pollution-free vegetables.
3, as far as possible to apply non-polluting plant pesticides, plant pesticides, raw materials, wide source, simple production, not only good anti-disease effect, and no side effects. For example, using 1.5kg of fresh bitter eucalyptus leaves and adding 1.5kg of water, filtering and removing slag, 1kg of juice and 40kg of water spray can control cabbage caterpillars and vegetable mites. Add 1 part of water with 3 parts of skunk leaves, soak for 1-2 days, spray the water immersion liquid and spray it to prevent aphids, cabbage caterpillars, etc. In addition, plants such as garlic, pepper, fish vine, ramie, and onion all contain substances that inhibit pests, and can be used as long as they are processed slightly to control vegetable pests and diseases.
The chemical name of this polymer transparent material is polymethyl methacrylate, which is polymerized by methyl methacrylate polymerization.
Acrylic Plastic/PMMA is an important thermoplastic plastic that develops early.
Organic glass is divided into colorless, transparent, transparent, pearlescent and embossed plexiglass.
Commonly known as acrylic, organic glass in releasing the force that press a gram, gree, organic glass has good transparency, chemical stability, mechanical properties and weathering resistance, easy dyeing, easy processing, nice appearance, etc.
Organic glass is also called gelatin glass, acrylic and so on.
Species
Organic glass can be divided into four types according to their appearance.
Colorless transparent plexiglass is the most common and most used organic glass material.
Colored transparent plexiglass: commonly known as color board.
The light is soft, use it to make lamp box, handicraft, make a person feel comfortable and easy.
Colored organic
Pendant lamp
Pendant lamp
Glass: transparent colored, translucent colored, opaque colored three kinds.
The magnetic organic glass luster is not as bright as the pearl light organic glass. It is brittle, easy to break, suitable for making dial, box, medical device and the shape material of the characters and animals.
Transparent plexiglass: high transparency, proper lighting.
Acrylic Plastic/PMMA is made of the chandelier, exquisite and crystal clear.
Pearlescent organic glass:Acrylic Plastic/PMMA is used in the general organic glass to join the pearl powder or phosphor powder.
This kind of organic glass is bright and bright, the surface finish is high, after the outside form is hot pressed by the mould, even if the ground smooth polishing, still maintain the mould pattern, form the artistic effect of the unique thing.
Use it to make characters, animal models, trademarks, decorations and promotional materials.
Embossing organic glass: transparent, translucent, colorless, very brittle and break easily, used in interior doors and Windows and other decoration, has both the characteristics of pervious to light but not through the shape, usually used in indoor partition or space between indoor door window.
Applications:
1. Building application: window, soundproof Windows, lighting cover, telephone booth, etc
2. Advertising applications: light boxes, signs, signs, display, etc
3. Transportation application: train, car, etc
4. Medical application: baby care box, various surgical medical devices and supplies: bathroom facilities, crafts, cosmetics, scaffolds, aquariums, etc
5. Industrial application: surface plate and cover, etc
6. Lighting applications: fluorescent lamps, chandeliers, street lampshades, etc
7. Home application: fruit plate, tissue box, acrylic art painting and other household products
Advantages:
1. The aesthetics of organic glass: mirror effect, fine workmanship, no wrinkles, no seams;
2. The visual effect of plexiglass: the color is varied and the visual impact is strong;
3. Light transmittance of organic glass: the transmittance can reach 96%, the transmittance is excellent and the light is soft;
4. The impact of organic glass: it is more than 200 times that of ordinary glass products, and there is almost no danger of breakage;
5. Durability of the organic glass: the product has good protection for the built-in light source, which can prolong the life of the product.
6. The resistance of organic glass: it can be preserved for a long time, and the quality of the plate can be used for 6 to 13 years;
7. Flammability of organic glass: no spontaneous combustion and self-extinguishing;
8. Energy conservation of organic glass: it is very good for light transmittance, relative to reduce the source of light, save electricity and reduce the cost of use;
9. Reasonability of organic glass: reasonable design and waterproof, open structure, easy to clean and maintenance
