【 Building materials network 】Use acetylene burning spray gun to adjust the gas volume to zui large, and spray gun mouth distance coating The coating is 15cm, the nozzle is kept still for 30 minutes, and the coating is applied with heat resistance steel plate Gradually melting, there is no change in the coating, which causes the coating to fall off from the molten steel plate. At the same time, according to Zhisheng Weihua high-temperature coating experts, the acetylene combustion temperature can reach 2800 ℃ - 3000 ℃.

Prepare for the test experiment. Materials required: 0.5D heat-resistant pot shaped steel plate, 1kg ZS-1023 ultra-high temperature oxidation resistant coating, and 1 brush, Sandpaper One piece, a set of acetylene spray gun, a preheating oven and a steel clamp. The coating temperature resistance test was conducted in a ventilated environment.

Construction in the early stage of the test, coating preparation: ZS-1023 temperature resistant 3000 ℃ ultra-high temperature oxidation resistant coating is used after mixing and fully mixing. The paint is inorganic paint, which can only be applied on the surface of inorganic materials, not on the surface of organic materials. When there are objects that have been applied with organic materials, the organic materials should be cleaned before painting. The coating shall be applied after being stirred evenly. The thickness of ZS-1023 temperature resistant 3000 ℃ ultra-high temperature anti oxidation coating shall be controlled below 0.1mm for each coat. During painting and testing, ZS-1023 temperature resistant 3000 ℃ ultra-high temperature anti oxidation coating is a pure inorganic coating, which has no odor at high temperature and normal temperature, no VOC component, no toxic substances, and no harm to human body.

After painting, test the sample, place the ZS coating test sample in a ventilated environment for 24 hours, place it in a drying oven, gradually raise the temperature, finally raise the temperature of zui to 500 degrees, stop for 1 hour, and then gradually lower the temperature and take it out. After taking it out, the acetylene spray gun can be used for combustion test under high temperature flame.
