2012-6-4 17:27:47

With the development of the paint industry, some organic paint has been unable to meet the concept of people's green, multi-functional and excellent performance, the development of ceramic paint opened up the progress and research to the field of high-tech paint to further meet the people to enhance paint The performance of the vision. Based on existing domestic research a number of ceramic paint, succinctly described the excellent performance of a variety of ceramic paint, and the latest research and development, preparation method and mechanism of these ceramic paint, summarized, summarizes, and further put forward the idea of ​​some of the ceramic paint and improvements. In particular, high temperature ceramic insulating paint principle and performance of Jane v. as follows:

Ceramic insulating paint functional paint the field, is a new water-based inorganic paint, which is based on nano-inorganic compounds as the main ingredient, and water as the dispersion quality of the coating after curing, usually after low-temperature heating the formation of performance and ceramic insulation coating. Institute of Aeronautical Materials Beijing Zhi Sheng Weihua Chemical Co., Ltd. to jointly study the development of high temperature ceramic insulating paint, performance has exceeded the advanced level of international insulating paint. Chi Sheng Wei Hua, high temperature insulating ceramic insulation, heat resistance, abrasion resistance and high hardness, good oxidation resistance and thermal shock resistance, moderate thermal expansion coefficient, excellent performance, so it is suitable for supersonic aerospace spacecraft high temperature structural materials under high temperature insulation. ZS-1091 Zhi Sheng temperature ceramic insulating paint, special high temperature solution using Chi Shing Wai Wah, long-term temperature can reach 1800 ° C, water-based inorganic ceramic materials, paint temperature solution of pure inorganic polymer, pigments with high resistance inorganic crystal material fine processed. Insulating paint at 1700 ℃ for a long time work, the volume resistivity greater than 1016Ωm dielectric strength (breakdown strength), is greater than 104KV / m, good chemical stability, aging resistance, corrosion resistance, good oxidation resistance , no flash point, ignition point, high hardness, hardness greater than 7H. ZS-1091 Zhi Sheng Weihua temperature ceramic insulating paint, maximum temperature of 1700 ° C can be formed in the object surface to be coated with a layer of high volume resistivity, can withstand the strong electric field without breakdown. The coating has high mechanical strength and good chemical stability, the ability of aging, water resistance, chemical corrosion; also are resistant to mechanical shock and thermal shock performance, Zhi Sheng Wei Hua insulation coating in the appropriate operating temperature Continuous operation ZS-1091 high temperature ceramic insulation paint is water-based inorganic high temperature paint, using a proprietary high temperature solution of the pure inorganic polymer composition of the high resistance inorganic crystalline materials such as alpha-alumina, silicon nitride, senior mica, etc. The filler composition of the coating volume resistivity (> 1012Ωm), dielectric strength (above 104KV/mm) suitable for brushing in a variety of fire-resistant cable, high temperature insulation. Paint after sintering of the fire, the formation of a hard ceramic-like shell of isolation layer, the isolation layer of hard ceramic-like shell can be very effective at blocking the flame continues to spread, to protect the normal state of the matrix is ​​not compromised. It is the birth of insulation problems for human research opened up a new idea and method.

In order to ensure the effective increase of the ceramic coating associated with the performance, to improve the quality of the preparation of the sample surface with a complex shape ceramic coating. ZS-1091 Zhisheng high temperature insulating paint production process, strict control of paint raw materials, production processes, to avoid the bulk ions or metal molecules, ion mixing, to maximize the raw materials of glass phase, reduce raw material for glass bring two times coatings conductivity. Chi Sheng Wei Hua insulating paint fine production but also to strengthen the generated link details such as temperature, humidity, atmosphere, to avoid unnecessary paint with a free ion, electron and hole bit and redox electronic, but also to avoid the depth of processing in the production of inorganic lattice material conversion caused by lattice defects, so as not to affect the conductivity of the coating.

Today's domestic ceramic insulating paint, the main function of insulation, high temperature, corrosion resistance, good mechanical properties and other characteristics, usually using a different preparation methods, some of the unique nature of the filler and additives to the corresponding prepared with the corresponding function of the ceramic paint. and strengthened its own performance. Green, low carbon, low cost, simple preparation, the concept has been widely popularized, so with the nature of the ceramic paint will be further improved and R & D in the future. Such as: inorganic water-based ceramic paint will gradually replace the past organic paint; low carbon emissions, high efficiency, versatility of ceramic paint on paint important position.
