Ceramic insulating varnish belongs to the field of functional lacquer. It is a new type of water-based inorganic lacquer. It is based on nano-inorganic compounds and has water as dispersion 010-5718-2232.
Ceramic insulating varnish is a new type of water-based inorganic lacquer. It is a new type of water-based inorganic lacquer. It is based on nano-inorganic compounds and is dispersed in water. It is usually cured by low-temperature heating after coating to form a similar performance to ceramics. Insulation coating film. At present, the National Aeronautical Materials Research Institute and Beijing Zhisheng Weihua Chemical Co., Ltd. have developed the high-temperature ceramic insulating varnish successfully after years of joint research and experiments. The performance has exceeded the advanced level of international insulating varnish and has been used in the Shenzhou series of aircraft. High temperature resistant insulating ceramic insulating varnish is excellent in insulation, temperature resistance, wear resistance and high hardness, good oxidation resistance and thermal shock resistance, moderate thermal expansion coefficient, etc., so it is very suitable for high speed structure of supersonic spacecraft. The material is used under high temperature insulation.
High temperature resistant ceramic insulating varnish, using Zhisheng Weihua special high temperature solution, long-term temperature resistance can reach 1800 °C, water-based inorganic ceramic material, paint using pure inorganic polymer high-temperature solution, pigment is made of high-resistance inorganic crystal material. Insulating varnish can work at 1700 °C for a long time, volume resistivity is greater than 1016 Ωm, dielectric strength (breakdown strength), greater than 104KV/m, good chemical stability, aging resistance, corrosion resistance, oxidation resistance, no Flash point, ignition point, high hardness, hardness greater than 7H. ZS-1091 high temperature ceramic insulating varnish, the highest temperature resistance of 1800 °C, can form a layer on the surface of the object to be coated with a higher volume resistivity, can withstand a stronger electric field without being broken down.
ZS-1091 high temperature ceramic insulating varnish coating has high mechanical strength and good chemical stability, can resist aging, water and chemical corrosion resistance; it also has mechanical shock resistance and thermal shock resistance. Zhisheng Weihua insulation coating can be used in Continuous working under the corresponding working temperature, high temperature ceramic insulating varnish is waterborne inorganic high temperature lacquer, using proprietary pure inorganic polymer high temperature solution, composed of high resistance inorganic crystal material, such as α-alumina, silicon nitride, high-grade mica The sheet is composed of a filler, the coating has a high volume resistivity (greater than 1012 Ωm) and a high dielectric strength (higher than 104 KV/mm), and is suitable for coating high temperature insulation on various fire resistant cables. The lacquer is sintered by fire to form an insulating layer of a hard ceramic-like casing. The insulating layer of the hard ceramic-like casing can effectively block the continued spread of the flame and protect the normal state of the substrate from damage. Its birth has opened up a new way of thinking and new methods for human research on insulation.
