Optical stabilizer can inhibit or reduce light degradation, improve the light resistance of the polymer and composite. Since most of the light stabilizers absorb ultraviolet rays, these substances are often referred to as ultraviolet absorbers. The photostabelling agent has a significant effect on the prevention of the photocondens of the composite material, and the dose is also small, generally only the mass of the polymer ~.
The ingredients are dissolved with potassium sorbate kg, and dissolved white sugar is added.
Stabilizer 2020 supplier The yellow original gelatin is added to 1 kg of citric acid and the right amount of water. The stabilizer is dissolved, and the xanthan gum kg is heated to dissolve with a proper amount of water, and there is no agglomerate without impurities.
1,6-Hexanediamine, N,N-bis(2,2,6,6-tetramethyl-4-piperidinyl)-, and 2,4,6-trichloro1,3,5-trichloro oxazine, reactant with N-butyl-1-butylamine and polymer of N-butyl-2,2,6,6-tetramethyl-4-piperidinamine factory 1,6-Hexanediamine, N,N-bis(2,2,6,6-tetramethyl-4-piperidinyl)-, Polymers manufacturer Solubles are dissolved in the sandwich pot, 100 kg of white sugar is dissolved with 150 kg of water, heated to 100 ° C, heat insulation for 10 to 15 minutes, filtered with 80 mesh sieve, requiring no eye to visible impurities.
Due to its high security, especially in food packaging and HD hard polyethylene products, it is also widely used in plastic doors and windows, water supply pipes, decorative materials, and substituting other high toxic plastic thermostats. It has been widely used in the United States, Europe and Japan. In recent years, 181 methyl tin heat stabilizers have been widely used in China. 3. Flame retardant is an additive to improve plastic flame resistance.
Dual-phase emotional disorders can be cured, and preferred drugs are emotional stabilizers. As the name suggests, emotional stabilizers are to make emotions as stable in the normal range, don't ignore it. Emotional stabilizers mainly include lithium salts, propharvinic salts, lam triazine, kamasipine, octazapine, quetiacene, chlorosa, rispernone, and the like second generation anti-psychotic drugs.
Tangshan recovered natural resin high quality service chemical additives, especially the chemical additives required for a certain industry, including non-metal processing additives, plastic additives, paper additives, building additives, water treatment additives, coating additives, leather additives, textiles Printing and dyeing additives, etc. 1. Chemical additive product segmentation 1. Rubber plastic additive detection plasticizer, plastic flame retardant, antioxidant, stabilizer, foaming agent, rubber additive, anti-aging agent, antifoaming agent, regenerative gelatin, plastic agent, etc. ; 2. Water treatment agent detection of corrosion inhibitor, water quality stabilizer, flocculant, fungicide, chelating agent, etc. ; 3. Surfactant detect sodium stearic acid, sodium dodecyl benzene sulfonate, quaternary, industrial ethoxylated fatty amine, industrial triophosphate, sodium ethoxylated alkyl sulfate, layered crystallization Sodium di - silicate, industrial alkane sulfonate, fatty acid glycerides, etc.
1. Any company that uses organotin plastic stabilizers must establish a chemical composition management system of the original accessories, prevent the harm of trimethyl chloride (TMT), strictly control the procurement, prevent the procurement and use of organotin plastic stabilizers.
2. Check the sump extrusion, due to the basic problem of the ditch, the project quality is or very common. 1. Before the pipeline is installed, it should be carefully examined whether the HDPE double wall bellows material is damaged during loading and unloading, such as finding damage cracks, deformation, etc., should be removed in time. Installation consideration: No heavy metal stabilizer does not add heavy metal stabilizer during the processing of good environmentally friendly performance, material non-toxic, is a green pipeline material, and the polyethylene material itself can be recycled and impossible to pollute the environment. Dalingshan professional double wall corrugated tube with customers for Zunlonghua electric fuse tube parts wholesale 3 long service life. Polyethylene tube molecular mass is high, good coordination, good anti-aging. Under normal operating temperatures and pressures, the service life guarantees more than 50 years.
Soil tin stabilizers mainly include fatty acid salts, maleate and thiol. The fatty acid salt type has a significant initial coloring, but since it is used together, it is often used with other stabilizers; the maleate type can prevent initial coloration, which can be used as a primary stabilizer. However, due to the lack of lubricity, the soft formula is serious, the amount of adds in the product should not be too large; thiol tin is the best performance in the current stabilizer. It has highlighted thermal stability and transparency, no initial coloration, suitable for hard transparent products. However, thiol tin is expensive, and the smell is rich, this is a disadvantage.
But another cross-linking method-irradiation cross-linking can greatly increase the working temperature of the polyolefin (mainly polyethylene), and the irradiation of foreign countries can be increased to 180 ° C. Mainly converted to a stable key energy by high energy electron, enhance the thermal stability of its molecular structure, and divided into different heat resistance based on the efficiency of the energy level and the efficiency of the heat stabilizer.
Lianyungang plastic toothpick box processing. The polyvinyl chloride film is required to prevent heat decomposition during processing, and a heat stabilizer is required. Since the thermal stabilizer contains lead and salt, the polyvinyl chloride plastic has properties, so it cannot be used as a food packaging. Industry Development Editing Annual Plastics Industry has a series of economic planning and industrial revitalization planning, which will stimulate the demand and consumption of plastics and promote the development of the plastics industry.
