Latest trends in the development of high temperature coatings

Resistant high temperature coating development is followed by high temperature industrial development, industrial high temperature conditions on high temperature coating technical requirements higher, such as high temperature insulation insulation, high temperature anti oxidizing, Chi Sheng Wei Hua high temperature insulation coating, thermal radiation energy-saving, high corrosion resistance, and the technical index is higher.
Years of continuous research and development, a number of high temperature coatings R & D results, Sheng Weihua to high temperature coating technology indicators have significantly improved. High temperature coating temperature resistance, decided to adopt the Zhi Sheng Wei Hua high temperature solution index and high temperature coating binder should also be the complementary properties of composite binder, in order to make the coating not only has high strength, but also has high toughness, but also high temperature. These many aspects of performance requirements are generally single binder can not be achieved. At the same time, but also adding dispersant, surface active agent, film forming material and other auxiliary components, in order to make the coating has good film forming performance, suspension performance, etc..
High temperature coating powder material mainly silicon carbide, zirconia or zirconium oxide powder, chromium oxide, manganese oxide, etc.. But these high temperature resistant materials at high temperature are very different, with SiC high temperature radiation rate increases to a limited extent, and occurred in the high temperature and oxidation reaction of the radiation performance is suppressed; and ZS high temperature coating zirconia or zirconium English sand powder, zinc oxide chromium powder material material radiation rate with elevated temperature decreased in addition to radiation base material.
Also high temperature coating inorganic filler particle size, but also determines the performance index for high temperature coating, inorganic filler of ultrafine and nano increases the average spacing between the particles, reducing the number of particles per unit volume, reducing the density, can improve the coating compactness. For example Beijing Zhi Sheng Wei Hua ZS-1023 ultra high temperature metal anti oxidation coating, long-term high ultra high temperature can reach 30 DEG C, can be very good to protect the metal not under the high temperature oxidation corrosion, can effectively prevent high temperature oxygen penetration to the substrate, high hardness, impact resistance, linear expansion coefficient is high, reting coefficient. ZS-1023 ultra high temperature metal anti oxidation coating technology research and development in the world leading level, technology content high with high melting point, antioxidant, thermal shock resistance, thermal expansion coefficient, low volatilization at high temperature and excellent ductility and fatigue resistance of. Beijing Zhi Sheng Wei Hua Chemical Co., Ltd. with high temperature and high pressure synthesis of C-C and pb-c synthetic Zhi Sheng Wei Hua special high-temperature solution, forming continuous three-dimensional network crystal structure solution, the high temperature synthesis of inorganic carbon system solutions, high temperature resistance, no volatilization, good ductility, high into the membrane can be long-term work in 3000 DEG C high temperature environment, not aging. Good adhesion. High temperature processing of oxide yttrium trioxide two dysprosium, SrZrO3, SiC, ZrB2 pure inorganic material is selected in the powder coating, choice of inorganic materials melting point are in more than 3000 DEG C, high temperature oxidation and volatilization, high-temperature lattice conversion and solution to form a coating is compact, oxygen permeability low and diffusion of oxygen has better inhibitory effect, ductility.
High temperature coating superfine particles on a substrate adhesion is extremely strong, and even part of very fine particles can penetrate into the substrate material, similar to infiltration aluminum, carburizing process, so as to completely change and strengthen the surface properties of the substrate material, completely eliminate peeling coating and decreased use of high temperature effect etc. phenomenon, resistance to high-temperature anti-corrosive paint ZS-811 Zhi Sheng Wei Hua years of research and development of the high temperature of 1800 degrees like, the coating with high fineness, surface even under extreme sudden cold and hot conditions, also won't have burst and peeling phenomenon. At the same time coating grain ultra refinement, nano, surface coating can greatly reduced, so that the surface coating non stick ash, non stick oil, is not easy to pollution, is not easy to be covered, the efficient utilization of the coating long-term stability is a reliable guarantee. Also ultrafine fundamentally completely solve the coating suspension and saved in a short period and the construction site easily by spraying construction method, which not only improves the construction conditions, to enhance the progress of construction and transformation, and can also save the coating amount, for the user save investment and renovation.
