White indoor non expansion type Fire retardant coating Price of one ton for two hours
White indoor non expansion fire protection coating The quotation is one ton for two hours. The fire resistance of the white indoor non expansive fire retardant coating is 2h and 2.5h/3.0h. Please consult the customer service for details. The indoor non expansive fire retardant coating is divided into gray and white, This product is made of light fire-resistant, thermal insulation materials and modified inorganic high temperature adhesive It is applied to the surface of indoor and outdoor steel structures to form a fire-resistant and thermal insulation protective layer. In case of fire, it can prevent the rigidity strength of the bearing column from dropping due to the high temperature of the fire. It plays the role of fire protection and thermal insulation. It has the advantages of high fire resistance and long fire resistance time. Due to low density, small volume consumption; It has strong cohesive force and good construction workability; Good acid and alkali resistance, usually protect the steel structure from the erosion and weathering of environmental factors, not easy to pulverize and other advantages; This product does not contain asbestos and harmful substances. It is non corrosive and green. It is suitable for beams and columns of steel structures with high fire resistance.
Construction method of indoor non expansive steel structure fireproof coating:
one Clean the floating dust and oil stain on the steel structure surface, and check anticorrosive paint Whether there is any missing coating. If there is, remove the rust first and then brush the antirust paint (the steel structure must be painted with qualified antirust paint, and the use of fake, counterfeit and inferior products is strictly prohibited).
two , also called priming, the ratio of liquid and powder provided by our factory is =5 ： three (weight ratio), the material is evenly mixed in the barrel with a hand-held stirring drill, and the spraying thickness is two — 3mm The left and right must be covered with full anti rust paint.
three The second time, after the first time is dry, it should be buckled by hand to see if it is firm before spraying. Use our liquid material: powder 5:3
(weight ratio), which can be used in blender It can be stirred evenly inside, and the spraying thickness seven — 9mm 。
four After the second coat reaches the surface dry, the third coat can be sprayed. The mixing method is the same as that of the second coat nine — 10mm 。
five When mixing liquid materials and powder materials, liquid materials shall be poured first according to the ratio for mixing two — three Minutes, and then add powder to mix ten — fifteen minute.
six The thinness and consistency of the prepared coating can be adjusted by adding a small amount of water.
seven Compressor air pressure ＞ 0.4mpa , the spray gun is away from the working face ≤ 35cm 。
eight The operating environment shall not be washed by rain, when the wind force> four Wind proof measures should be taken or construction should not be carried out. The coating after construction should avoid rain wash.
nine If the surface needs to be trowelled, start to trowel after the second spraying. The coating before troweling cannot be dry (if it is dry, apply a coat of glue on the coating surface before troweling). The thickness of troweling shall be three — 5mm It is suitable (wet, dry and smooth).
