The paint is hard and durable, and the adhesion is good If it is used in combination with phosphating primer, it can improve the moisture resistance, salt spray resistance and rust resistance of the paint film The fire protection mechanism of the fireproof paint can be summarized as follows: the fireproof paint itself is flame retardant or incombustible, so that the protective substrate is not directly in contact with the air, delaying the object fire and reduce the burning speed; In addition to its own flame retardant or incombustible, it also has a low thermal conductivity, can delay the flame temperature to the protection of the substrate transfer; fire paint heat decomposition of incombustible inert gas, dilute the protected object nitrogen-containing fire-resistant paint heat decomposition of NO, NH3 and other groups, and organic free radical compounds, interruption of chain reaction, reduce the temperature of the combustible gas, so that it is not easy to burn or burn speed slow down; expansion of the fire-proof paint thermal expansion foam, the formation of carbon foam insulation layer to protect the object, delay the heat and the substrate transfer, to prevent the object from burning or due to temperature rise caused by the strength of the decline

Q:I ask: I open the slot, take a good line, leaving the tank and the wall mud flat, and asked the need for the proportion of cement and sand is how much? What is the degree of water What type of cement? Do not appear after the mud can not scratch the wall, drop the problem. Thank you more
