Hot water temperature inorganic adhesive bonding better high temperature adhesives industrial boilers, which is resistant to high temperature must temperature, corrosion, abrasion and thermal shock resistance, high temperature refractory to improve performance . Since a long period at a temperature of the boiler state 900 ℃ -1100 ℃ work at this temperature refractory ceramic is difficult to achieve a sintered state, seriously affect the refractory properties. So the key to solve the problem is to achieve a high temperature ceramic sintering temperature state within the circulating fluidized bed boiler temperature range, resulting in a stable and good compressive strength and wear-resistant thermal shock resistance, Wei Sheng Zhi Hua ZS-1071 has a high temperature plastic conducive to more energy-efficient furnace.
In response, Beijing Zhi Wei Sheng Chemical Co., Ltd. developed a circulating fluidized bed boiler with a new type of high-temperature inorganic high temperature plastic, model ZS-1071, using the Chi Shing Wai Wah special high-temperature solution, temperature up to 1800 ℃. This kind of circulating fluidized bed boiler with high temperature rapid heating is a use of inorganic nano-materials made by the condensation reaction temperature inorganic nanocomposite temperature, filtered through the composition ratio and process parameters to obtain high temperature is PH suspended dispersion system is neutral, not only strong bond to the metal substrate and non-corrosive, high temperature inorganic refractory application temperature range, can maintain good adhesive properties and corrosion resistance at high temperature of 1800 ℃, long life, make more secure boiler operation.
The new type of high-temperature glue has the following characteristics:
(1) The new ZS-1071 high temperature plastic material used in advanced rare earth oxides. Can promote refractory sintered at 900 ℃ -1100 ℃ temperature conditions, so refractory to achieve high data compression strength, enhances the refractory wear, so that products can withstand high concentrations of dust erosion, reducing wear and tear , so it is suitable for use in a circulating fluidized bed boiler.
Super adhesive (2) high temperature plastic material, Chi Sheng Weihua temperature high temperature plastic and are bonded inorganic materials such as alumina, silica, alumina ceramic, graphite, carbon and carbides, high temperature refractory metals have good wetting and heat sealing properties. At high temperatures with good strength, at 1300 ℃ average compressive strength of 90MPa (MPa), a tensile strength of 8MPa (MPa). The high temperature and substrate thermal expansion coefficient is quite refractory to improve the performance of high-temperature plastic materials, and prolong life.
(3) high-temperature inorganic adhesive ZS-1071 uses a phosphate body temperature so that the product has a strong bonding ability and plasticity, with a temperature operability. Coating need be applied to the metal, graphite, and various high temperature materials formed on the surface a coating protective layer. For example: high-temperature oxidation protective coating of metallic materials, fire-retardant coatings, high temperature oxidation protection coating graphite material. Can also be used for high temperature furnace lining materials, as may be formulated into the overall construct aggregate materials and repair materials, masonry materials, unshaped refractory materials seams.
