Brief analysis of the classification and basic properties of release agents

The release agent is a high polymer such as a polysiloxane or an organic fluoropolymer, and the others are inorganic or organic.

Non-chlorofluorocarbons and water-based release agents are the development trend.

Commonly used is methyl silicone oil, the performance is as follows:

Colorless, odorless transparent viscous liquid, with molecular weight difference, ranging from 1 to 104 Pa·s, soluble in benzene, toluene, xylene, ether, etc., refractive index 1.38~1.40, density 0.82~0.97 g / cubic centimeter, thermal conductivity is 0.00028 ~ 0.00044 watt / (m · thousand), boiling point 152 ~ 250 ° C, flash point 110-600 ° C. The viscosity is different and the properties vary greatly.

Methyl silicone oil is commonly used for high temperature demolding of large injection molded parts.

Inorganic release agents include talc, mica powder, molybdenum disulfide, white clay, clay, etc., and other additives to form a release agent, which is mostly used in the rubber industry.

Organic release agents include fatty acid soaps (sodium soap, zinc soap, etc.), fatty acids, paraffin, white oil, petrolatum and the like. It can be considered as an internal or external lubricant of plastic.

In addition to methyl silicone oil, the high polymer release agent also has a low molecular weight polyethylene (also a lubricant, a dispersant), a polyethylene glycol, an epoxy derivative, a fluorine compound, and the like.

Temporary Fencing Panel

Temporary fence is suitable for temporary isolation, temporary partition, temporary circle around, is a highly flexible product. Temporary guardrail from the process point of view can be divided into two kinds: 1. Temporary guardrail welded mesh 2. Braided mesh temporary guardrail. The main use of removable components will be the main guardrail with the base or guard column for standard connection, such as the specific needs of the time can be easily removed, for moving installation.
Main structural features: Mesh is relatively compact, strong base security, handsome in appearance, according to customer needs custom-made production.

Packing: Nake or on pallet
