In order to delay and prevent aging, stabilizers must be added. Mainly used to prevent thermal aging, referred to as thermostat; mainly used to prevent oxidation, referred to as an antioxidant; mainly used to prevent optical aging, referred to as a light stabilizer, collectively referred to as a stabilizer. Today's plastic stabilizer is a methyl tin heat stabilizer (hereinafter referred to as 181), extension of hard polyethylene (PVC), extrusion, injection molding, and blow molding. Due to its high security, especially in food packaging and high-definition hard polyethylene products, it is also widely used in plastic doors and windows, water pipes, decorative materials, and substituting other high toxic plastic heat stabilizers. High-density polyethylene geomembrane is a new type of anti-seepage anti-corrosion material, widely used in the projects of various anti-seepage anti-corrosion requirements. High density polyethylene is mainly made of high-density polyethylene, about% carbon black, micro antioxidant and heat stabilizer, anti-aging material, ultraviolet absorber, no other additives, fillers, and expansion agents, three-layer co-extrusion technology become. The resin used is a native polyethylene resin designed for the application of a flexible anti-graft film. Experts on the test results of the anti-seepage film construction site show that the performance indicators of the HDPE anti-seepage film have reached or exceed the GRI-GM13 standard. The UVA length is used as a auxiliary light stabilizer and a barrier light stabilizer, especially in polyolefins or coatings. (4) Quenching agent: The energy absorbed in the plastic, propagates in the form of heat, fluorescent or phosphorescence, returning the substrate to protect the polymer from ultraviolet. When selecting a light stabilizer, a stabilizer that is easy to absorb or reflect this part of the sensitive wavelength should be selected. At the same time, it is also considered whether the sensitive wavelength of various polymers is consistent with the effective wavelength range of the ultraviolet absorber. (2) The role of other additives: Since the ultraviolet absorber absorbs light energy, the possibility of heat generation is increased, and antioxidants and heat stabilizers must be added, which requires three synergies. In addition to emulsification, Taicang surfactants can also adsorb the metal surface to form a lubricating film, reduce workpiece, debris, tool, mold interface metal direct friction, enhance the lubricating effect, 2, emulsified stabilizers emulsified stabilizers are mainly used for emulsifiers. There are two aspects of the emulsifier stabilizer: one is to completely dissolve soap in the emulsifiable oil and other additives. Soy products need to be added to a coagulant, stabilizer, etc. in the production process, and melamp can affect the gel process of the protein. Li Meng et al.N,N-bis-(2,2,6,6-tetramethyl-4-piperidinyl)-1,6-hexanediamine and 2,4,6-trichloro-1,3,5-tris The reaction product of oxazine polymers and 1,1,3,3-tetramethylbutylamine manufacturer  Graded magnesium chloride and Guur gum (about 4.9: 1). In the tofu production, it was found that the addition of Guur gum increased the first stage rate of the solidification process, and the quality structure characteristics of tofu were changed, and the hardness was significantly reduced. Through the anti-aging study of Hongyun bean sand, it is determined that the optimal addition ratio of the aging of the bean sand filling is 2 ‰, Guarou gum is 3 ‰. The addition of Guapal gum can improve the processing characteristics of the soy product as a quality improvement. Road sealant strictly implements industry standards, and various indicators are better than industry standards! During the production process, SBS in road petroleum asphalt needs to change through three processes of expansion, shear and development, and add other imported additives to improve road performance. In this process, as the temperature increases, the expansion speed is significantly accelerated, and the SBS is close to the aromatic density. The shear and multiple grinding are then performed, and the asphalt and SBS reach a uniform mixing and high dispersion.Hindered amine light stabilizer 944 supplier  During this process, a quantifier stabilizer, an anti-aging agent, a wear resistant, or the like are added to ensure a longer life of the road seal. The polymer additive can make the material smoothly, achieve better properties, can be divided into process additives and function additives. Process additives can improve production efficiency, and functional additives can significantly improve the performance of materials, so a wide range of applications. Among them, stabilizing additives, ie anti-aging agents, is the company's main products, can delay aging and degradation of materials during storage, transportation, and use, thereby extending the service life of the product. Antioxidants are mainly used to inhibit the thermal oxidation degradation process of the polymer; the light stabilizer is also known as the ultraviolet stabilizer, which can effectively reduce the damage of the ultraviolet pair of polymers. 1.HALS-944 factory SMA is a asphalt macadi binding material consisting of asphalt, ore powder, and fiber stabilizers, filled in a batch of mineral skeletons. Tin stabilizer. The organic tin stabilizer and PV resin have good compatibility, and there is a tendency of severe adhesion metal walls. It is a paraffin-stearate system that matches a paraffin-stearate system with a balanced lubricant. The matching outer lubricant 5 is selected depending on the stabilizer. Other additive color and other profiles of outer lubricants and stabilizers are used as aging resistant, and titanium must be added. The formulation of hard PV tubes is mainly pigment, mainly titanium or carbon black, and can be selected according to the requirements of the pipe. The third chapter analyzes the production of ultraviolet stabilizers in the world, output value (10,000 yuan), growth rate, market share and future development trend, mainly including the United States, Europe, Japan, China, Southeast Asia, Europe, Japan, China, Southeast Asia and India.
