As photoinitiator, it is mainly used for silk screen printing ink, lithographic printing ink, flexo printing ink and wood coating. TPO can be completely cured on the pigmented surface of white or high titanium dioxide. It is widely used in various coatings. Because of its excellent absorption performance, it is especially suitable for silk screen printing ink, lithography, flexographic ink and wood coating. The coating does not turn yellow, the post polymerization effect is low and there is no residue. It can also be used for transparent coating, especially for products with low odor requirements. When used alone in unsaturated polyester containing styrene system, it has high initiation efficiency. Acrylate systems, especially colored systems, usually need to be combined with amine or acrylamide and other photoinitiators to achieve complete curing of the system, especially for low yellowing, white systems and thick films. When the photoinitiator TPO is used with mob240 or cbp393, the curing efficiency can be improved. It is the best extraction solvent for petroleum aromatics units and is also used as formylation reagent in fine chemical industry.

As a water retention agent in the food industry, it is used in cans, fruit juice drinks, dairy products, meat products, cheese and beverages. In chemical, textile, printing and dyeing, papermaking, power generation and other industries, it is used as water softener and detergent, boiler scale inhibitor, water softener in paper dyeing, pH buffer of chemical Book adhesive for wax paper production, color fixing agent during printing and dyeing, mercerization enhancer of fabric, and anti embrittlement agent for thread making. Metallurgical industry is used for chemical degreasing and decontamination, and as an excellent accelerator in photographic development solution. Tooth cleanser and bottle detergent. A coagulant for rubber milk. Sugar juice purifier.

Silica is the most abundant of all minerals. Silica in nature is called silica, which accounts for about 12% of the total weight of the earth's crust. There are three different crystal forms of silica: quartz, scaly quartz and cristobalite. Quartz is the most stable at room temperature and the other two are stable at high temperature. They also exist at room temperature because of their slow transformation into quartz.

It is used in the production of liquid crystal, medicine, dye, pesticide intermediates, etc.

It is mainly used as water purifying agent for drinking water and precipitant for wastewater treatment and purification. The printing and dyeing industry is used as oxidant and mordant in indigo dyeing. Catalyst for organic synthesis of dichloroethane and other production. Chlorinated extractant for silver and copper ore. An etchant for photographic and printing plate making. Raw materials for manufacturing iron salts such as iron phosphate, medicine, pigment and ink. After infiltrating its solution into the building concrete, it can increase the building strength, corrosion resistance and prevent water seepage. It is used in the production of circuit board and fluorescent digital tube in electronic industry. Coagulant for recovering glycerol from waste liquid of soap production.
