1. Structure and classification of MQ resinMQ silicone resin is a kind of silicone resin with unique structure. It is a three-dimensional spherical structure silicone grease produced by CO hydrolysis and polycondensation of organosilicon compounds containing four functional siloxane chains (SiO4 / 2, q) and silicone compounds containing single functional siloxane chains (r3sio1 / 2, m). Its molar mass is generally between 1000 and 8000g / mol. it has the state from viscous fluid to solid powder, ...

The first snow of 2020 is coming, I am waiting for you at SILIBASEIn winter in Zhejiang, snow began to fall in many places in Zhejiang last night, and some people have piled up snowmen. Last night, the cold air has entered the northern part of Zhejiang. Huzhou, Jiaxing, and Hangzhou have signed for receipts. Small partners in other parts of the province Cold Air The courier also knocked on the door one after another. With the arrival of a "quick-freezing" cold air, many places in Zheji ...

The curing reaction of two-component RTV release agent does not depend on the moisture in the air, but on the catalyst.Chemical agent to initiate. The rubber and catalyst are usually packaged as one component. Curing begins only when the two components are completely mixed together.The curing time of two-component condensation RTV release agent mainly depends on the type, amount of catalyst and temperature. The more the amount of catalyst, the faster the vulcanization, and the shorter the shelvi ...

Silicone resin coating is a kind of elemental organic coating, which takes silicone resin or modified silicone resin as main film-forming material. Elemental organic coatings are the general name of coatings with organic polymers as the main film-forming materials, including organosilicon, organic titanium, organic fluorine, organic aluminum, organic zirconium coatings, etc. Among them, the output of silicone resin coating is the largest. Element organic coating is a kind of compound between org ...

Silicone building waterproof agent: methyl silicone alcohol sodium waterproof agent made by unique 1 technology. Its oxygen ion content is close to zero, which is different from the traditional production process. It is not only non corrosive to the reinforcement, but also has the function of moisture-proof and anti-seepage, as well as air permeability. Easy to use: direct spraying, high efficiency (especially for the leakage of the external wall, in the case of no re laying, the use has excelle ...

Softener is a kind of chemical substance which can change the static and dynamic friction coefficient of fiber. When the static friction coefficient is changed, the handle is smooth and easy to move on the fiber or fabric; when the dynamic friction coefficient is changed, the micro structure between fibers is easy to move, that is, the fiber or fabric is easy to deform. The combination of the two is softness. Softeners can be divided into cationic, nonionic, anionic and amphoteric quaternary amm ...

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 ...
