NCB ultra-thin steel structure Fire retardant coating introduce
NCB ultra-thin steel structure fire protection coating When exposed to fire, the foaming component in the coating film of the product is decomposed by heat, and the expansion and thickening produce a dense and uniform fireproof and thermal insulation protective layer, which can generate decomposition endothermic reaction, prevent heat transfer, delay the temperature rise of the steel structure, and greatly improve the fire resistance time of the steel structure. The coating is a kind of fireproof coating for steel structure with good expansion and thermal insulation performance under fire and good decorative performance. In the indoor ultra-thin steel structure fireproof coating, Waterborne paint It can be made with clean water diluent Without any corrosion protection Primer Chemical reaction; The oily coating needs to be diluted with special diluent. Compared with the water-based fireproof coating, it is more convenient for winter construction and can be prepared into various colors according to the needs of users. The ultra-thin fireproof coating for steel structure has the advantages of ultra-thin and flat coating, strong adhesion, good fire resistance, good decoration and convenient construction. It can be widely used in industrial and civil steel structure workshops, gymnasiums, exhibition halls and other steel structure buildings for fire protection.
Construction method
1. The construction of ncb ultra-thin fireproof coating fireproof coating shall be carried out after the acceptance of steel structure works, the installation of pipe fittings connected to steel structures, the completion of roof waterproof works, before indoor decoration and without damage by subsequent works.
2. Before the construction of fire retardant coating, the dust, oil stain and sundries on the steel structure surface shall be cleaned and derusted, and anti rust primer shall be applied to ensure that there is no chemical reaction with the fire retardant coating. The fireproof coating can be applied only after the anti rust paint is dry. During construction, the mechanical equipment and other components that do not need fire protection shall be shielded and protected.
3. The coating shall be fully stirred before use. When the coating is slightly thick, the water-based coating shall be diluted with water; Oil shall be diluted with special diluent, and the degree of dilution shall be convenient for spraying and non flowing.
4. The construction tools should be gravity type or bucket type spray guns, equipped with air compressors that can automatically adjust the pressure of 0.6~0.9 ㎡/mm, the nozzle diameter is 4-6 mm, and the air pressure is 0.4-0.6 MPa. For local repair and small area construction, the surface decorative coating can be brushed, sprayed or roller coated. In case of manual brushing, the number of brushing passes will increase accordingly. When spraying the next coat of paint, it must be dried after the previous coat.
Cleaning and maintenance of ultra-thin fireproof coating:
1. Clean construction tools with matching solvent.
2. Please follow the local * * * requirements for disposal of waste liquid after cleaning.
3. The coating maintenance period is 7 days (25 ℃).
Packaging and storage:
1. This product is an oily coating.
2. The product should be stored in a ventilated and dry place at 5-40 ℃ to avoid rain and direct sunlight.
3. See the label for the net content, storage period, production date and batch number of the product.
