Fire retardant coating for steel structure has remarkable performance of fire insulation, moisture proof and corrosion proof.It is widely used for steel structure fire protection of indoor and outdoor buildings and structures whose fire resistance time is less than 2.5 hours.To prevent the initial misfire and slow down the expansion of the misfire, steel structure fire retardant coating is a new type of fire retardant coating developed by using new technology road.It is characterized by the formation of a uniform and dense sponge - like foam insulation layer in case of fire.
It is especially suitable for the protection of exposed steel structure in stadiums and industrial plants. Its use: steel structure fire retardant coating is important for the fire protection of indoor steel structure and steel products in industrial and civil buildings.To effectively advance the fire resistance of steel structure, implement the requirements of building imaginary fire protection standards, and at the same time have good decorative results.
The construction request
Details of steel structure fire retardant coating:
After sand blasting to reach the scale of SA2.5, coated steel structure fire retardant coating of the steel substrate details should be strictly water removal, rust removal.Manual rust removal to ST3 or above.The details of the complete rust removal using alkyd red lead or epoxy antirust paint as anticorrosive treatment.
The construction way
Low pressure airless spray can also be used.Directly divided coating according to the fire resistance limit, roller coating or brush coating can be used.After the previous coating surface is dry and then coated again.When operating this coating, the fireproof sealing finish must be operated to prevent the crushing of the fireproof coating in the rain and high humidity environment. The consumption is 0.25kg/m2.Stir thoroughly until there is no sediment before operation.The relative humidity is less than 85% when painting.
Thickness of coating: The thickness of wet film for each fire retardant paint should be no more than 250um.
Coating distance: surface dry (finger touch not sticky)
Dilute cleaning: 2001 special dilution cleaning agent.
Or by the product morality custody agency arbitration.If it still does not conform to this technical standard, the acceptance delimitation rules: if the unit that operates the steel structure fire retardant coating finds that the character of the product does not conform to the provisions of this standard, the two parties shall jointly re-inspect it.The operating unit has the right to return the goods.
Marking, transportation, packaging, storage:
The unused coating packaging should be re-sealed to prevent drying for reuse. Under the transportation and storage conditions suitable for this standard, the storage period of the product shall be one year from the date of production.The outer wall of each can shall have a mark, statement, product title, batch number of production, title of production unit, place and date of production.Sealed tin cans, net weight of each can is 20kg, stored in a cool and ventilated dead plate.The products should be protected from rain, sun exposure, water intrusion and pay attention to seal during transportation.
