How much is the gypsum base price of the renovated fireproof coating for steel structure? The gypsum base price of the renovated fireproof coating for steel structure does not expand in case of fire after being sprayed on the surface of steel members. The fireproof and thermal insulation protective layer is formed by the incombustibility and low thermal conductivity of the coating itself, which delays the direct invasion of fire on the load-bearing members, thus effectively improving the fire resistance of steel structures. The product has the advantages of high temperature resistance, non combustible in case of fire, no smoke emission, acid and alkali resistance, long shelf life at room temperature, and can be cured at room temperature. The scope of application is applicable to all kinds of new construction, expansion and reconstruction of industrial and civil construction projects (ordinary/special) steel structure indoor components

How to make gypsum based fire retardant coating for indoor wall gypsum based fire retardant coating for indoor wall gypsum based fire retardant coating for steel structure consists of tackifying primer and main section, which can be constructed with common plastering tools and spraying tools. Steel members (such as steel beams and columns) provided for construction shall be derusted, painted with red lead antirust paint or alkali resistant antirust primer according to GBJ20583 and CECS24:90. Before construction, dust, oil and other sundries on the steel parts shall be removed, and then the construction shall be carried out in the order of bottom material first, then main material. Construction method The bottom material construction is divided into powder and liquid materials, which are mixed in a ratio of 1:0.9

Construction Process Flow Diagram of Steel Structure Gypsum based Fire Retardant Coating Construction Process Description 1. Base treatment: before construction, remove the dust, oil and rust on the steel parts, and then brush two layers of anti rust paint on the steel parts. The next process can be started only after no brushing phenomenon is found. 2. Fire retardant coating construction: the fire retardant coating construction can be divided into two types: with metal mesh and without metal mesh. (1) Add metal mesh to fix the metal mesh: after the anti rust paint is dry, cut the metal mesh according to the shape of the steel piece, fix it on the steel piece with a steel bar clamp, and then use a pre welded steel bar to flatten the warped part of the metal mesh, so that the mesh and the steel piece
