| 耐火纤维增强涂料是由硅酸盐的衍生物和三氧化二铝胶体以及无定型高温氧化物在一定的条件，按一定的比例配制而成的快速胶结绿色稠状物。 The fire-resistant fiber reinforced coating is a kind of fast cemented green thickener, which is made up of silicate derivatives, alumina colloid and amorphous high-temperature oxide in a certain proportion under certain conditions. 耐火纤维增强涂料工艺流程 Process flow of refractory fiber reinforced coating 把高温纤维涂料喷涂在纤维制品表面后，在室温下，由于涂料中自由水的蒸发，胶体逐渐凝结成多分子的胶体颗粒，进而变成一些相互胶结的细线状结构，牢固地吸附在纤维和颗粒表面，使表面产生胶结。当开始升温时，涂料中残存的自由水分继续蒸发，并且开始析出结晶水，导致胶粒进一步缩合，使涂层进一步硬化。随着温度的不断升高，表面涂层的强度也进一步加强，并且在较低的温度范围内，涂料中的高温氧化物与非晶质玻璃相中的物质相结合，逐渐陶瓷化。 After the high temperature fiber coating is sprayed on the surface of fiber products, at room temperature, due to the evaporation of free water in the coating, the colloid gradually condenses into multi-molecular colloidal particles, and then becomes some mutually cemented fine linear structures, which firmly adsorbs on the surface of fiber and particles, resulting in cementation on the surface. When the temperature starts to rise, the residual free water in the coating continues to evaporate, and crystal water begins to precipitate, which leads to further condensation of the rubber particles and further hardening of the coating. With the increasing of temperature, the strength of the surface coating is further strengthened, and in the lower temperature range, the high temperature oxide in the coating combines with the material in the amorphous glass phase, and gradually ceramic. |
