Low-temperature solidification spray coating and construction method thereof
The invention discloses low-temperature solidification spray coating, comprising a dry material and an inorganic binding agent, wherein the dry material is formed by stirring and mixing flint clay granules, electric ceramic granules, mullite granules, mullite fine powder, white corundum powder, activated aluminium oxide powder, nanoscale silicon micro powder, Guangxi white mud and a PT organic binding agent, wherein the inorganic binding agent is liquid sodium silicate. The scientific grain size distribution is adopted, and the materials such as the nanoscale silicon micro powder, the activated aluminium oxide powder and the inorganic binding agent which are added in a compounding way enable the spray coating to be solidified under a low temperature condition, so as to form a whole high-intensity low-temperature solidification lining body; the inorganic binding agent and the organic binding agent mutually react to improve the construction performance of the spray coating, so that the rebound is lowered to10 percent. After being used during the construction of a large sintering flue, a warm-air pipeline, a dust removal pipeline and the like in practice, the spray coating can be solidified to form the whole high-intensity lining body by self-combination under lower temperature without sintering, thus obviously reducing material consumption and achieving the aim of energy conservation and emission reduction.
