How to calculate the cable fireproof coating? The calculation of cable fireproof coating is 1.2 * 103/m3. One square meter of cable is brushed with 1m2/1.2kg of fireproof coating. Wg=K ×π× D × LWg - coating amount (kg); D --- Cable outer diameter (m); L --- brushing length (m); K - unit consumption (kg/m) When the coating thickness is 0.8mm, K is taken as 2; When the coating thickness is 1.0mm, K is taken as 2.5; When the coating thickness is 1.2mm, K is taken as 3 for the construction of cable fireproof coating. 1. Before the construction of cable fireproof coating, the floating dust, oil, etc. on the cable surface shall be removed

The thickness of fireproof coating for steel structure of the first level fire resistance rating is 3h. The thickness of fireproof coating for steel structure is 23mm. The thickness of thin fireproof coating for steel structure can be used for 2.5h. The thickness of coating is only 4.7mm. The first level fire resistance rating for general buildings requires 3h for steel columns, 2.5h-2.0h for steel beams, and 2.0-1.0h for accessories. The fireproof coating can be used separately. 1. Ultra thin fireproof coating for steel structure, with coating thickness less than or equal to 3mm. 2. Thin steel structure fireproof coating, with coating thickness greater than 3mm and less than or equal to 7mm. 3. Thick

Ultra thin fire-retardant coating manufacturer Steel structure 3c approved fire-retardant coating company Steel structure ultra-thin fire-retardant coating oil and water manufacturers, national standard steel structure 3c approved fire-retardant coating company, ultra-thin steel structure fire-retardant coating products are divided into water and oil (solvent). 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 steel structure with good expansion and thermal insulation performance under fire and good decorative performance

Fire retardant coating construction cable process spraying fire retardant coating construction method of cable fire retardant coating: 1. Before the construction of cable fire retardant coating, the floating dust, oil stain, sundries, etc. on the cable surface shall be cleaned and polished, and the construction of fire retardant coating can be carried out after the surface is dry. 2. Spraying, brushing and other methods shall be adopted for the construction of cable fireproof coating, which shall be fully stirred and evenly used. When the coating is slightly thick, it can be diluted with appropriate amount of tap water to facilitate spraying. 3. During construction and before the coating is dry, it shall be waterproof, sun proof, anti pollution, anti movement and anti bending. If there is any damage, it shall be repaired in time. 4. For wires with plastic and rubber skins

The density of cable fireproof coating is * * * good or low. The density of cable fireproof coating is 1.2/m2 according to the national standard. The cable fireproof coating is used on the surface of combustible substrate, which can reduce the flammability of the surface of the coated material and prevent the rapid spread of fire. It is a special coating used to improve the fire resistance limit of * * * the coated material. Fireproof coating applied on the surface of the base material, in addition to its flame retardancy, also has the properties of rust prevention, waterproof, anti-corrosion, wear resistance, heat resistance, as well as the toughness, coloration, adhesion, dryness and glossiness of the reinforcement material, which can effectively prevent the spread of fire. The coating has good fire and moisture resistance, acid and alkali resistance, and oil resistance
