Now there is an inorganic water-based adhesive with temperature resistance of more than 2000 ℃, fire retardant, molding bonding, nonvolatile, industrial bonding material, which is ZS-1071 high-temperature resistant adhesive produced by Hubei Zhisheng Weihua New Material Technology Co., Ltd adhesive The high temperature modified solution specially made by Zhisheng Weihua is used, and the temperature resistance can reach 2200 ℃. The solution has good modeling and high density and hardness. High temperature resistance, stable performance at high temperature, high bonding strength at room temperature and high temperature, high linear expansion coefficient, strong resistance to oxygen and sulfur gas corrosion, good thermal shock coefficient, convenient construction, no VOC generation, good performance bonding effect, Zhisheng Weihua ZS-1071 high temperature resistant mastic adhesive has a wide range of applications, and can be applied to various inorganic materials Between metal and refractory, repair of high-temperature refractory, high-temperature kiln Lining material repair and high-temperature powder bonding.
Product advantages
ZS-1071 high-temperature resistant mastic adhesive (high-temperature resistant repair mastic) is a new product with its own intellectual property rights. Zhisheng Weihua ZS-1071 high-temperature resistant mastic adhesive is a kind of inorganic adhesive nanometer The high-temperature resistant inorganic nanocomposite binder made of materials through polycondensation reaction is a suspension dispersion system with neutral PH value through screening of composition ratio and preparation process parameters, which not only has strong adhesion but also has no corrosiveness to metal matrix. Zhisheng Weihua ZS-1071 high-temperature resistant mastic adhesive (high-temperature resistant repair mastic) has a wide application temperature range, It can maintain good adhesion, wear resistance and corrosion resistance at 2200 ℃, and has a long service life.
Product composition
coating High temperature resistant inorganic silicate modified solution specially made by the company is used as Film-forming substance , adding yttrium oxide, lanthanum oxide, cerium oxide, neodymium oxide and other rare earth oxides, zirconium powder, etc. as filler. The cured film can resist high temperature and energy up to 2200 ℃. Under high temperature environment, it can maintain good thermal stability, bonding performance, wear resistance and corrosion resistance. It can be directly applied at high temperature of 400-1000 ℃, and the film performance will not be affected.
Bonding mechanism
The solution used for high-temperature resistant inorganic adhesive is re chelated after high-temperature modification. The modified solution has better stability under high temperature conditions, better film forming type, and higher density hardness. The addition of powder filler requires high-temperature and high-pressure treatment of dispersed silicon carbide, rare earth oxide, zirconium powder, etc., which has high linear expansion coefficient at high temperature and strong resistance to oxygen and sulfur gas corrosion. Especially after the coating is cured at room temperature three hundred The volume will shrink after sintering at high temperature above 3%-5% The coating becomes denser and the bonding strength is higher.
Main purpose
It is used for bonding various inorganic materials, such as metal to metal, metal to refractory, graphite, refractory, high-temperature refractory repair, high-temperature kiln lining material repair and high-temperature powder bonding.
Product parameters
Construction requirements
Ensure that the painted surface is free of dust, oil stain, rust, brittle layer and other foreign matters, and ensure that the painted surface is clean and dry without pollution. Polish and roughen the coated surface as much as possible to ensure the surface roughness within the range of 25-40 μ m. If the metal surface is manually polished to St3 or sandblasted to Sa2.5, the coating effect will be better.
