Rubber and plastic products in the mold processing, rubber and plastic materials and mold surface contact, may be due to the mold surface concave and convex and other micro defects, rubber and plastic products from the mold stripping will have a certain friction resistance. In the process of injection or extrusion of rubber and plastics, negative pressure is often formed between the rubber and plastic materials and the mold, or the adhesion between them is caused by physical adsorption or chemic ...

Softeners can be divided into fatty acid derivatives and organosilicone oil. The former is a traditional softener widely used, and the latter is a new product coming from behind. The development of silicone softeners is very fast, and new varieties with various properties and functions are being developed and put on the market.Silicone softeners not only have better softening effect than traditional softeners, but also have better durability. Therefore, in the use of textile soft finishing, has ...

It is used for waterproof and protection of porous inorganic base (such as concrete, ceramic tile, clay brick, stone, etc.) without water pressure.It is used for waterproof and impermeability, anti fouling, color retention and anti weathering of brick wall, facing brick wall and coating, natural stone facing external wall. Tile and other external wall waterproof, does not change the original base color. The cost is 2 yuan / M? Silicone emulsion building repellent is sold in the original solution ...

Softener is a kind of chemical substance that can change the static and dynamic friction coefficient of fiber, which can adsorb on the surface of textile fiber and smooth the fiber, so as to change the handle and make the product more comfortable. In order to let you have a better understanding of softeners, today we will introduce the classification and characteristics of softeners. Softeners can be classified in terms of their ionic properties and main components.Softener is a kind of chemical ...

Siloxane oligomers have a series of unique and excellent properties. The thermal stability, impact strength, adhesive strength, lubricity, flame retardancy, solvent resistance, air permeability and leveling property of ordinary polymer materials modified by siloxane oligomers can be improvedLeveling agent is a kind of commonly used coating additives. After coating construction, after flowing and drying, a flat, smooth and uniform coating film is formed gradually. The leveling property of coating ...

After brushing, the treated surface will dry naturally, and the crystal structure of the product will be frozenusage methodTo ensure the best effect, rinse immediately;In winter, if the temperature is too low, immersion, before construction, roller and sealed spray gun can be used for construction;Apply the second coat before the surface is dry; Clean the substrate surface before use.matters needing attention. It can also be used in concrete to restore the transparency of the solution. If there ...

The silicone mold release agent is an "oil-in-water" type silicone oil and water emulsion made by emulsifying and grinding silicone oil. Keep the mold surface lubricated, reduce mold loss, and save mold maintenance and repair costs.advantage1. Silicone mold release agent is a new type of product developed mainly for the mold release of silicone rubber accessories, trademark rubber molds, and silicone keys. It has the characteristics of excellent mold release, smooth product surface, an ...

Silica gel (Silica gel; Silica) Alias: Silicone rubber is a kind of highly active adsorption material, which is an amorphous substance, and its chemical formula is mSiO2.nH2O. It is insoluble in water and any solvents, non-toxic, tasteless, chemically stable, and does not react with any substances except strong alkalis and hydrofluoric acid.According to its properties and components, silica gel can be divided into organic silica gel and inorganic silica gel.Organic silica gel is an organosilicon ...

Add materials 5, 6 and 7 into a clean and dry reaction flask with a stirring and reflux device, and gradually add a mixture of 1, 2, 3, 4 and 8 from the feeding port under stirring to maintain 20-40 The dripping is finished for about 1~1.5h between °C. Then the temperature was raised to 80C, and the ethanol produced in the reaction was evaporated. After most of the ethanol is evaporated, the temperature is raised to 120-130C, connected to a decompression system, the residual ethanol is removed ...

Surfactant Surfactant is a molecule formed by two completely different particles, one particle has a strong lipophilicity, and the other has a strong hydrophilicity. After being dissolved in water, surfactants can reduce the surface tension of water and improve the solubility of organic compounds. A wide range of surfactants (cationic?, anionic?, non-ionic and amphoteric) provide multiple functions for specific applications, including foaming effect, surface modification, cleaning, emulsion ...
