After the fire retardant coating is used, a complete acceptance work must be carried out to ensure that no problems will occur when it is put into use.
Thick film steel structure fire retardant coating should meet the following requirements:
1. The thickness of the coating meets the design requirements. If the thickness is lower than the original standard, it cannot be less than 85% of the original standard, and the length of the continuous area of the part with insufficient thickness is not more than 1m, and similar situations will no longer occur within 5m;
2. The coating should be completely continuous and should not be exposed or missed;
3. The bond between the coating and the steel substrate and between the coatings should be firm, without hollowing, delamination, looseness, etc.;
4. There should be no protrusions on the coating surface. For parts with appearance requirements, the allowable deviation of the bus bar's non-straightness and roundness should not be greater than 8mm.
Thin-film fire-retardant coatings for steel structures should meet the following requirements:
1. The coating thickness should meet the design requirements;
2. There should be no paint leakage, powder peeling and obvious cracks. If there are individual cracks, their width should not be greater than 0.5mm;
3. The bond between the coating and the steel substrate and between the coatings should be firm, without delamination, hollowing, etc.;
4. The color and appearance comply with the design requirements, with clear outlines and smooth joints.
Cable fire retardant coating application directions and product construction methods. When the cable fire retardant coating is on fire, it can generate a uniform and dense sponge-like foam insulation layer, which can effectively prevent and block the spread of flames and protect wires and cables. Its main advantages are: environmentally friendly, non-toxic and odorless, and does not pose a threat to the health of applicators.
