How much do you know about the organic pigment industry? Below, the editor summarizes our overview.
Silicone oil is a type of polyorganosiloxane with a chain like structure with different degrees of polymerization. It is prepared by hydrolysis of dimethyl dichlorosilane with water to obtain an initial condensed ring body. The ring body is cracked and distilled to obtain a low ring body. Then, the ring body, sealing agent, and catalyst are mixed together to obtain a mixture of different degrees of polymerization. After vacuum distillation, the low boiling substance is removed to produce silicone oil.
Organic silicon solid powder coating is a powder with a solid content of 50% and loss of luster, mainly used in water-based coatings, adhesives, lubricants, cutting oils, grinding fluids, diesel, kerosene, lubricants, cleaning agents, emulsified asphalt, resins, lubricants, building coatings, industrial rust prevention coatings, dye pigments and other industrial sectors.
Silicone oil is a non-toxic and odorless transparent liquid, odorless, non flammable, and non explosive. It can be used for a long time at temperatures of -50 ° C to 200 ° C and has excellent electrical insulation.
Silicone oil is a non-toxic, odorless, non flash point, non flammable, colorless and transparent liquid with properties such as high temperature resistance, low temperature resistance, chemical resistance, and radiation resistance.
Silicone oil is a non-toxic, odorless, and non flammable mixture with high temperature resistance, corrosion resistance, low temperature resistance, non flammable, non polluting physiological solvents, and non-toxic properties. However, when in contact with the eyes, a large amount of fog is generated, which not only affects eye health, but also causes a symptom of titanium dioxide reaction when exposed to sunlight or other wavelengths for a long time.
Silicone oil is generally a colorless (or light yellow), odorless, non-toxic, and nonvolatile liquid, insoluble in water, methanol, and ethylene glycol, and volatile with benzene, dimethyl ether, oxidants, drinking water, and steam.
The main amount of fabric flame retardants is roughly understood based on the variety of fabric. (1) The flame retardancy of knitted fabrics is the main amount of polyester fibers and polyester fibers, which depends on wool and grafted fibers.
Impregnation method: Fabric impregnation method: (1% water droplets are exposed), 2% ammonia water is used to wash the hot water on the fabric. During the fabric desizing operation, the dyeing status of the fabric can be observed.
● Immersion method: (1% of foam is before exposure), 2% of ammonia will wash the hot water off the fabric, dehydrate during desizing, and keep the dyes and knitted fabrics soft at about 50 ° C.
Immersion method: (1% aluminum hydroxide solution, continue heating for 40 minutes, and maintain a consistent temperature between the dye and the fiber.).
When selecting dyes, it is necessary to determine based on fiber material, depth, smoothness, and color matching amount, otherwise it may cause color change.
Taking an appropriate amount of high concentration metal whitening agent can cause significant yellowing during high-speed scanning, while other plastic products may experience slight discoloration during coloring, but it is not recommended.
