Hefei thin steel structure Fire retardant coating Supplier
Fire protection of ultra-thin steel structure coating It refers to the fireproof coating for steel structure with coating thickness less than 3 mm (including 3 mm), good decoration effect, expansion and foaming at high temperature, and fire resistance limit generally less than 2 h. This kind of fireproof coating for steel structure is generally a solvent based system, which has superior bonding strength, good weather and water resistance, good leveling, good decoration and other characteristics; When exposed to fire, it slowly expands and foams to form a dense and hard fire insulation layer, which has strong fire resistance impact, delays the temperature rise of steel, and effectively protects steel members. Ultra thin intumescent steel structure fireproof coating can be applied by spraying, brushing or roller coating, which is generally used on building steel structures with fire resistance limit less than 2h.
Hefei thin steel structure fireproof coating supplier NCB indoor ultra-thin steel structure fire retardant coating has been inspected by the National Quality Supervision and Inspection Center for Fixed Fire Extinguishing Systems and Fire Resisting Components in accordance with GB14907-2018 General Technical Conditions for Steel Structure Fire Retardant Coatings, and its physical and chemical properties are qualified, with the fire resistance limit Z up to 2.0h. The coating has the advantages of strong adhesion, long durability, thin coating, high fire resistance and easy construction. The coating expands rapidly in case of fire and forms Sponge The thick fire insulation layer makes the steel structure not easy to bend and collapse in case of fire, and extends the fire resistance time of the steel structure to achieve the fire protection effect.
Waterborne ultra-thin steel structure fire retardant coating is a new type of water-based fire retardant coating, which is applied to the surface of steel members in buildings and structures, and then applied to the surface of steel members. In case of fire, the coating rapidly expands to form a carbonized fire-resistant and thermal insulation protective layer, thus improving the fire resistance limit of steel structures.
Construction process:
1. Rust removal and rust prevention of steel member surface before fire retardant coating Primer The painting shall comply with the design requirements and the current relevant national specifications, and the dust, oil stain and other sundries on the surface of steel members shall be completely removed. Fire retardant coating shall be applied before interior decoration and under the condition that it will not be damaged by subsequent works.
2. During construction, the wall surface door Windows, mechanical equipment and other components shall be shielded and protected.

4. The thickness of one coat of brushing shall be suitable to cover the base course, generally not more than 0.5mm. The next coating can be carried out after the previous coating is dry. The thickness of each coat can be increased appropriately from the second coat, but it is better not to flow.
5. After the first dry, use sandpaper to polish off the brush marks on the coating, which can better reflect the decorative effect.
6. This product can also be coated by spraying method, and the coating steps are basically the same as the brushing method.
Construction precautions:
During the construction process and before the drying and curing of the coating, the ambient temperature should be kept at 5~45 ℃, the relative humidity should not be greater than 90%, and the air should be circulated. When there is condensation on the component surface, construction is not suitable. During construction, the thickness of coating shall be measured at any time according to the fire resistance limit. This product is a water-based fire retardant coating, so the coating should be placed indoors or in the rain shelter to avoid rain whether during or after construction.
The reference dosage is 2.2kg/m2.
