Ultra-thin steel structure fire [department] Liu Shi 18983090999,023-68170198 paint coating thickness in millimeters (mm); indoor ultra-thin fireproof coatings based on natural or synthetic polymers (emulsion) is foundation and assists foaming agent, foaming agent aids, carbon and other components for composing the expansion system, again with a variety of fillers and reinforcing ingredients and additives made hybrid. Ultra-thin steel structure fire coating formed at ordinary room temperature, the expansion charring effect of fire protection in case of fire, ultra-thin fireproof coatings excellent UV resistance, water resistance, good acid and alkali resistance, fire resistance, long life, There are certain decorative effect. Thin steel structure fire retardant coating for outdoor steel, fire insulation to protect the steel platform, steel girder roof trusses, concrete structures. Person in charge of thin steel structure fire retardant coating construction project in the purchase of paint and coatings specifications, will be issued with reference to the Party in the steel construction drawing requirements for fire resistance of the fire-resistant coating. On the information provided in terms of customer service and elegant, most customers will put fire retardant paint and anti-corrosion coatings requirements confusion. So that the customer service staff confused. Until technicians see design drawings, I would understand, customers continue to emphasize the corrosion thickness requirements, and will μm as the mm. First, brushing the thickness of fire retardant coatings, also made a detailed explanation before the small series. Here again a brief review. Brushing coating thickness according to fire can be divided into: ultra-thin fireproof coatings, thin fireproof coatings and thick coating steel structure fire three. Coating thickness does not exceed the ultra-thin fireproof coatings, can be spray, brush or roller application, on the requirements for general use within 2h fire resistance of construction steel of 3mm. Coating thickness 3 ~ 7mm of ultra-thin fireproof coatings, decorative good than thick coating type, construction spraying, generally used in the fire endurance requirements do not exceed 2h of construction steel. Coating thickness 8 ~ 50mm thick coating of fire-retardant paint, fire resistance of up to 0.5 ~ 3h. Construction general spraying, multi-application requirements of the fire resistance of indoor steel on more than 2h.
