TPE typically adds a staminated and phosphite antioxidants, a thiosteide thermal stabilizer, a stearic acid lubricant, and the like. On the one hand, the addition of these additives can prevent degradation of the polymer during processing, and on the other hand, if the combination is improper or purity, the additive itself degrades some small molecules.
(3) Quenching agent: The energy absorbed by the chromophore in plastics is accepted in the form of heat, fluorescent or phosphorescent, protecting the polymer from ultraviolet termination. It has good stability to the polymer, mainly for films and fibers. Mainly some divalent organic nickel chelate.
2-[2-Hydroxy-5-(1,1,3,3-tetramethylbutyl)phenyl]benzotriazole supplier Ultraviolet Absorber UV-329 manufacturer Organic nickel-optic stabilizers are good, but due to the toxicity of heavy metal ions, it can be replaced by other non-toxic or low toxic quenches.
To prevent synthetic resins from being decomposed and destroyed during processing and use, extending the service life should be added to plastics. Commonly used stearate, epoxy resins, and the like.
The main process is a high-density polyethylene, a carbon black compound, an anti-aging agent, an antioxidant, an ultraviolet absorber, a stabilizer, and the like, which are made of four-layer co-extrusion technique.
Complexing: Chelate stabilizer can form chelate with heavy metal ions, reduce or eliminate hydrogen peroxide decomposition of heavy metal ions, preventing the catalytic decomposition capability of heavy metal ions being greater than the adsorption stabilizer. Most of these organic acid polyvalent chelating agents can be divided into carboxylic acid, phosphonic acid, and carboxylated groups. The main disadvantage of chelating stabilizers is that it is not possible to enrich heavy metal ions like adsorbent, and cannot chelate catalytic decomposition of hydrogen peroxide impurities other than metal ions, moreover, without saying that the large bath of the crawler equipment is bleached.
Ingredient (MIT) methylisothiazolinnone and (BIT) phenylopenyl isomothiazolin double component compound, current coating, building emulsion, adhesive and other market top fungicide formulations, completely free of stabilizers and metal salts, Without formaldehyde and VOC, the paint emulsion is good, no flocculation is not stimulated, no yellow discoloration, the worker's skin is stimulated, the powder mineral is not reactive, MIT and Bit have long stable, high temperature resistance to strong base is high-grade emulsion , Water, water, water, water-based emulsion resins, industrial coatings preferred fungicides are one of the best fungicides in the market.
Konjac is widely used as food and food additives: konjac powder as thickeners and stabilizers, can be added to jelly, jam, juice, vegetable juice, ice cream, ice cream, etc., solid beverage, seasoning powder and soup powder; konjac powder As the binder, it can be added to the noodles, rice noodles, twisted, meatballs, ham sausages, bread and pastries to enhance the muscle strength, keep fresh; konjac flour as a gel, can be added to various soft candies, leather In sugar and crystal sugar, it can also be used to make bionic foods; researchers have found that the glucono content of white konjac reaches 60% (dry base), which is much higher than the konjac.
The main type of heat stabilizer is a lead salt in accordance with stabilizers, organotic tin stabilizers, calcium zinc composite stabilizers, and the lead saline stabilizer has a certain harm to the environment and has been prohibited by the EU laws and regulations. Although my country has not issued laws and regulations prohibiting the use of lead saline stabilizers, with the increasing importance of environmental protection, lead salt stabilizers are inevitably replaced by more environmentally friendly products.
Improper stabilizers tend to cover a wax-like substance on the surface of the delay (including the flower roll), resulting in difficult the surface of the membrane surface not only in the production process, but also occurs when replacing the product. The higher the calendering temperature, the more serious this phenomenon. The reason for the waxy substance is that the compatibility of the stabilizer and the resin is high, and the molecular polarity group is high, resulting in a cruating inclusion, is being packed in the roll surface to form a wax. Raw materials such as colors, lubricants, and felt, may also form a waxy layer, but it is worse than the stabilizer.
The polyvinyl chloride floor refers to a floor made of a polyvinyl chloride material. It is the main raw material based on polyvinyl chloride and its copolymer resin. Add filler, plasticizers, stabilizers, colorants, and the like. On the sheet-like continuous substrate, the coating process is produced by calendering, extrusion or extrusion.
Cyasorb UV-5411 factory The polyvinyl chloride floor is a very popular newcomer, the world's light and decent ground decorative materials, also known as light texture. Since the 1980s, it has begun to enter the Chinese market. So far, China's large and medium-sized cities have been widely recognized. Very extensive, such as family, hospital, school, office building, factory, public place, supermarket, business and elsewhere.
