ceramic coatings
, a concise account of the excellent insulation properties of various ceramic coatings, as well as its latest research and development, at the same time, the preparation methods and conditions of these ceramic coatings are summarized, summarized, and further put forward some ideas and improvements related to ceramic insulation coatings.
ceramic insulation coatings open up new areas of high-tech coatings
in particular, Zhisheng ZS high-temperature ceramic insulation coating principles and properties are as follows:
ceramic insulation coatings belong to the functional coating field, is a new type of water-based inororally inorant coating, it is nano-inorderable compounds as the main component, and water as a dispersion, after coating is usually after low temperature heating curing, the formation of performance and ceramic similar insulation coating. At present, the National Aviation Materials Research Institute and Beijing Zhisheng Weihua Chemical Co., Ltd. after many years of joint research experiments, the successful development of high temperature ceramic insulation coatings, performance has exceeded the international advanced level of insulation coatings, has been used in the Shenzhou series of aircraft. High temperature insulation ceramic insulation coating its insulation, temperature resistance, wear resistance and high hardness, good antioxidant and heat shock resistance, medium coefficient of thermal expansion and other excellent performance, so it is very suitable for ultrasonic spacecraft high temperature structural materials under high temperature insulation.
ZS-1091 Zhisheng high temperature ceramic insulation coating, the use of Chisheng Weihua special high temperature solution, long-term temperature resistance can reach 1800 degrees C, water-based inorganic ceramic materials, coatings using pure inorganic polymer high temperature solution, pigments using high-resistance inorganic crystal material finishing. Insulation coatings can work for a long time at 1700 degrees C, volume resistivity greater than 1016 sm, dielectric strength (breakout strength), greater than 104KV/m, good chemical stability, anti-aging, corrosion resistance, good antioxidant, no flash point, ignition point, high hardness, hardness greater than 7H.
ZS-1091 Zhisheng Weihua high temperature ceramic insulation coating, the highest temperature resistance of 1700 degrees C, can be applied to the surface of a layer with a higher volume resistivity, can withstand a strong electric field without being pierced. The coating has a high mechanical strength and good chemical stability, can withstand aging, water, chemical corrosion resistance, but also has resistance to mechanical impact and thermal impact performance, Chisheng Weihua insulation coating can work continuously at the corresponding operating temperature ZS-1091 high temperature ceramic insulation coating for water-resistant inorganic high temperature coating, the use of proprietary pure inorganic polymer high temperature solution Liquid, composed of high-resistance inorganic crystal materials, such as α-alumina, silicon nitride, advanced mica, etc. for filler composition, coating volume resistivity is high (greater than 1012 sm), dielectric strength is high (higher than 104KV/mm), suitable for brushing on a variety of refraoring cable high temperature insulation. The coating is sintered by fire to form an insulation layer of a hard ceramic shell, which can very effectively block the continued spread of flame and protect the normal state of the substation from damage. Its birth has opened up a new way of thinking and method for human research on insulation.
in order to effectively improve the properties associated with ceramic coatings and improve the quality of ceramic coatings on sample surfaces with complex shapes. In the ZS-1091 Zhisheng high temperature insulation coating production process, in strict accordance with the standards of the Aerospace Research Laboratory, control the production process of coating raw materials, avoid scattered ions or metal molecules, ions mixed in, as far as possible to improve the glass phase of raw materials, reduce the raw materials used for glass phase to bring secondary coating conduction. Zhisheng Weihua high temperature insulation coating fine production should also strengthen the production of link details, such as temperature, humidity, atmosphere, etc., to avoid unnecessary paint with free ions, cavity electron bits and reduced oxidation of electrons, but also to avoid the production of deep processing inorganic lattice material conversion caused by lattice defects, so as not to affect the conductivity of the coating.
Today's domestic ceramic insulation coatings, the main functions of insulation, high temperature, corrosion resistance, good mechanical performance and so on, usually use different preparation methods, some fillers with unique properties and additives to prepare the corresponding functions of ceramic coatings, and to strengthen its own performance. And because now green, low-carbon, low-cost, simple preparation process and other concepts have been widely popularized, so some ceramic coatings with these properties will be further enhanced and developed in the future. Such as: inorganic water-based ceramic coatings will gradually replace the past organic coatings, such as low carbon emissions, high efficiency, versatility of ceramic coatings in the field of coatings, to contribute to the continuous development of industrial technology.
