Solvent-free impregnating varnish is widely used in the VPI insulation treatment of motor coils in high-end fields such as high-voltage motors, high-speed traction motors, and spacecraft engines. Silicone materials have the advantages of high temperature resistance and corona resistance, and are more suitable for insulation in the above fields deal with. With the continuous development of my country's high-speed railway, subway, light rail, and magnetic levitation technology, insulating material ...

Silicone resin materials are a kind of polymer materials with silicon-oxygen bonds as the main chain structure and organic groups as side groups. It has excellent thermal oxidation stability and insulation properties. Its service temperature can reach 200℃～220℃, and its heat resistance can even reach 250℃～300℃ after modification. At the same time, its molecular structure is close to that of silicate. It is a semi-inorganic polymer, so it has excellent insulating properties, with a dielectr ...

A silicone impregnating resin was synthesized from methylphenyl silane monomer and special silane monomer to prepare organosiloxane prepolymer. The impregnating resin does not contain any organic solvent and is a low-viscosity fluid liquid at room temperature. The structure and physical properties of the impregnated resin were characterized by infrared spectroscopy, nuclear magnetic resonance, scanning electron microscopy and gel chromatography. The results show that the polyorganosiloxane conta ...

The silane coupling agent  is mainly used for glass fiber reinforced plastics. The molecular structure of the silane coupling agent is generally: Y-R-Si(OR)3 (where Y is an organic functional group and SiOR is a siloxy group). Siloxy groups are reactive to inorganic substances, and organic functional groups are reactive or compatible to organic substances. Therefore, when the silane coupling agent is between the inorganic and organic interface, a bonding layer of organic matrix-silane coupl ...

Silicone rubber is divided into thermal vulcanization type (high temperature vulcanized silica gel HTV) and room temperature vulcanization type (RTV). The room temperature vulcanization type is divided into polycondensation reaction type and addition reaction type. High temperature silicone rubber is mainly used to manufacture various silicone rubber products, while room temperature silicone rubber is mainly used as an adhesive, potting material or mold. The hot vulcanization type has the larges ...

 Surfactant and its propertiesSubstances that can significantly reduce the surface tension of water are called surfactants. In recent years, surfactants have developed rapidly, and their applications involve many fields, such as oil field development, daily chemical products, coatings, food, textiles, materials, etc. Surfactants have almost penetrated into all production and technical fields.Surfactants have two important properties. They are directional adsorption on various interfaces, an ...

Waterproof gypsum board means that the water absorption rate of this kind of stone board is 5% when the standard is used for waterproof test, that is, it can be used in areas with high humidity, such as toilets, shower rooms and kitchens, etc. The board is added to the gypsum core material Quantitative waterproofing agent makes the plaster itself have a certain waterproof performance. In addition, gypsum board paper is also waterproofed, so this is a better board with a wider range of uses. Howe ...
