Gypsum based fireproof paint construction technology; Characteristic is once formed. Reduce the number of construction, save manpower, save materials. The spraying protection method, whether it is full protection or partial protection, should be implemented according to the design regulations. During the construction process, the author should use the thickness measuring needle to detect the coating thickness, until it meets the thickness specified in the design, the spraying can be stopped. If the coating thickness is not detected during construction, it is easier to cause some parts to be thick and some parts to be thin, and then it can not be accepted. Through detection, the coating thickness is uniform, and too thick spraying can be avoided.
Product description
This product is a wet fire retardant coating to provide fire protection for fiber fire, gypsum based material as the main body, adding a small amount of light material composite, using two construction methods of smearing or spraying, the exposed indoor components with a trowel smearing, can achieve a smooth surface decorative effect. It has the characteristics of high strength, good durability and smooth appearance. It is suitable for indoor steel bars, handle beams, joists, trusses, grids, steel stairs, molded steel plates, precast concrete members and other anti-wear or anti-damage steel components. It is tested and certified to provide fire protection to the structure for up to 4 hours. It is used in special use areas, transportation hubs, exhibition centers, stairwells, light production areas, facilities and equipment rooms in business office buildings. The basic color of the product is gray and white, and the net weight of each package is 25kg.
Basic requirements: Steel surface should be clean, no grease, lubricant, rust, and affect the adhesion of impurities.
Gypsum based fire retardant paint
Gypsum based fire retardant paint is composed of water resistance, salt spray resistance, weather resistance strong adhesive, heat insulation aggregate, reinforcing agent and performance regulator, asbestos free. It can be used for the fire protection engineering of load-bearing steel structures and open-air buildings, such as the support steel structure of open-air chemical equipment, the steel structure support of cable bridge, the protection engineering of outdoor steel structures such as petrochemical industry and metallurgy. After the coating meets the fire, the surface burns into a high-density oxidized glaze layer, which has the heat insulation function of preventing the spread of flame, and can significantly improve the fire resistance limit of the protected steel structure, so as to win the fire extinguishing time and keep the steel structure bearing the building.
