As a new coating material, polyurea has changed the concept and cognition of previous coatings by engineers and added new knowledge of coatings. Since the polyurea coating can withstand the full impact of a sledgehammer and the most severe abrasion, it also has satisfactory flexibility. When the obv

At present, the advantages of rigid polyurea with its excellent physical and chemical properties and advanced and convenient construction technology in the anti-corrosion application of the outer wall of the pipeline have been highlighted. Compared with 3PE, the rigid polyurea spraying equipment has

With the improvement of our quality of life, various scientific and technological building materials in our lives also appear in our daily buildings. Spray polyurethane is one of the more practical materials. Polyurethane is a kind of insulation and waterproof coating. Among them, its thermal insula

The spraying polyurea construction work should be carried out under the conditions that the construction environment temperature is greater than 5°C, the relative humidity is less than 85%, and the base surface temperature is 3°C greater than the dew point temperature.If the temperature of the const
