Polyvinyl chloride is a polymer that is polymerized in a vinyl chloride monomer in an initiator such as a peroxide, azo compound. Alternatively, the radical polymerization reaction mechanism is polymerized under photosensitiveness. Stabilizers, lubricants, auxiliary processors, pigments, anti-impact agents, etc. are often added to the actual use of PVC materials. It has less flammable, high strength, weather resistance and excellent geometric stability. PVC is generally used in plastic films, plastic shoes and leather products, films, cables and plastic bags. It can be seen that due to the photoinitiator itself. Light caused by debris. The resin has a suction shield for ultraviolet light, and the ultraviolet intensity of the ultraviolet penetrating coating reaches the substrate and the coating interface, causing the bottom of the coating to not completely cure, affect the adhesion of the coating 5. B: Use chemical dermatut agents, use acidic substances or corrosive substances, but the skin thickness and personal response are uncertain, resulting in proliferating scar registration, large area uses a negative effect on the body. Gongyi City, Gongchang, Hengchang Net Water Packing Factory ZGXEHCubdo8N9cmo reverse suspension polymerization is a relatively mature method of preparing polyacrylamide microspheres. Under strong agitation, the monomer or monomer mixture is dispersed in the medium (the medium is an organic solvent), which is fine particles, and then polymerizes in monomers, initiators, organic solvents, and dispersion stabilizers. After polymerization, the particle product can be obtained by boiling, dehydration, separation, and drying. The solid mass fraction obtained by reverse suspension polymerization is 90%. The polymerization rate is 95%. Monomer residue. The particle size is 10-500 microns, and the water solubility is good. Non-ionic polyacrylamides are mainly used as sewage treatment agents for acidic suspensions. Non-ionic polyacrylamide utilizes adsorption of its elongated molecular chain, so that the suspended particles are flocculated, and the purpose of purifying water is achieved.2-Isopropylthioxanthone Isopropylthioxanthone (ITX) 2-Isopropyl-thioxanthen-9-one 2-Isopropylthioxanthone Photoinitiator ITX 2-(1-Methylethyl)-9H-thioxanthen-9-one isopropylthioxanthone 2-Isopropylthioxanthone 2-Isopropylthioxanthone 2-Isopropyl-9H-thioxanthen-9-one Photoinitiator ITX PI-ITX supplier  Hangzhou fiber square tube manufacturers hot sale 2. Glass Steel Square Air conditioning is widely refreshing with home central air conditioning, which does not cause temperature difference and temperature difference, and the outdoor temperature is comfortable, but the split disc spring is small, it is impossible to prevent the temperature difference, the outdoor temperature difference, the outdoor temperature difference, The temperature difference is imbalance, and the comfort is not too high. 3. The appearance of the FRP square will inevitably damage most home decoration style of the house, and the company uses the channel of the glass steel to adopt hidden devices, and can be combined with home renovation, suitable for any styles. Anti-aging: Extruded profiles use high quality thermosetting resins. The glass fiber system is made, different from ordinary thermoplastics, and the normal service life of the product is up to 20 years. Adding UV and polyester fiber felts can achieve better anti-aging effects. The basic principle of LEDUV rubberization is that the photoinitiator in the ink absorbs ultraviolet radiation energy and activated. Its molecular external electron jumps, generates an active center in a short period of time, and then acts in an active center and an unsaturated group in the resin, resulting in a double bond in the photocurable resin and the active diluent molecule, and a continuous polymerization reaction occurs , Crosslinking each other, which is a way of radiation curing. It is an acid monomer as a main agent, a high-elastic gel that is cured under a certain curing agent at a certain curing agent. Similar to acrylic grouting liquid, low viscosity, and slow gel velocity than grouting. After the two-component mixed, poured into the surface of the tile, into the tile gap, cured into a high-elastic gel. It belongs to the environmentally friendly waterproof and anti-seepage grouting material, low viscosity, strong permeability; suitable for waterproofing and blocking of bathroom.Photoinitiator ITX manufacturer  The company is a national high-tech enterprise, jointly established Nankai University - Long-term New Materials Joint Institute, has established a strong technical strength and scientific research strength, and scientific and technological achievements. Rapid becomes real productivity, create greater value for society and the country. As of 30 November, the company is equally authorized to authorize patents, including 64 inventions, 20 new types (subject to the patent certificate). The company assumes a number of national and provincial key projects, and there are 1 national key new products. 3 Chinese patents excellent awards, 2 Tianjin patent gold medals, 2 Tianjin Science and Technology Progress Awards, 2 Tianjin famous trademarks, Tianjin professional new Products and other honors and title. Of course, the chlorinated agent also has a disadvantage. According to a research report of the "Professional and Environmental Medicine" of the British magazine, in the past few decades, the number of large numbers of children in developed countries increased, which may be related to children in indoor pools: and this effect The impact on young children is greater. The study pointed out that when chlorine passes through the pool water, it contacts the urine of the swimmer. When sweat and other organic components on the body, a nitrogen-trichloride which is easily inhaled is produced. Trichonized nitrogen may induce human body to produce three special proteins, which will damage the cell barrier for the lungs to protect the allergens to the lungs. Therefore, athletes' training and competition will also be affected by a certain extent. The 3D printing material under ultraviolet light becomes color, and the part exposed to visible light (such as projector lamp) will lose color and become transparent. These reactions are made of an underlying dye, a photoinitiator (curing ink during printing) and a light adaptive dye (color to the colors of the underlying dye).
