Surface treatment and storage methods for fireproof coatings in ultra-thin steel structures

There are significant fire insulation, moisture, corrosion and other properties. Widely used in fire-resistant ≤ 2.5 hours of indoor and outdoor buildings and structures of steel structure fire protection. For the initial fire prevention and slow fire extension, ultra-thin steel structure fire protection coating is a new type of fire protection coating developed by using new technology

. It is characterized by a fire to produce a uniform dense sponge foam insulation layer. It is of primary significance to guarantee the insurance of the country and the people's life industry.
is particularly suitable for the protection of exposed steel structures in sports stadiums and industrial plants, and is useful: ultra-thin steel structure fire protection coatings are important for fire protection of more fire-destroying objects such as indoor steel structures and steel products in industrial and civil buildings. Effective forward steel structure fire resistance, the implementation of the building hypothetic fire standards, but also has good decorative results.
construction request
ultra-thin steel structure fire protection paint details treatment:
by sand blasting rust removal to reach the sa2.5 scale, coated steel structure fire protection coating steel substrate details should be strictly dehydration, rust removal. Hand rust removal to st3 level or above. The details of the removal of rust are treated with acetic red dan or epoxy anti-rust paint for corrosion protection.
construction method
can also be used low-pressure airless spray. The necessary direct spread-through coating in accordance with the fire resistance limits can be applied with rollers or brushes. Wait until the coating table is dry and then apply it again. The fire-resistant closed finish must be operated to prevent the crushing of the fire-resistant coating by rainwater and high humidity environment, and the consumption of 0.25 kg/m2. The fire protection coating should be fully stirred to no sediment before handling. It is advisable for the relative humidity to be less than 85% during coating construction.
coating thickness: the thickness of each fire-resistant paint coating wet film should be ≤ 250um.
Coating distance: table dry (refers to non-sticking)
dilution cleaning agent: 2001 special dilution cleaning agent.
or arbitrate by a product character authority. If still does not meet this technical standard, acceptance and demarcation rules: the manipulation of ultra-thin steel structure fire-resistant coating units such as found that the character of the product does not meet the provisions of this standard by the two sides jointly re-inspection. The manipulator has the right to return the goods.
marking, transportation, packaging, storage:
unused paint packaging to be re-sealed, prepared dry knots, in order to re-use, suitable for the transport and storage conditions of this standard, the production date of the product, storage period of one year. The outer wall of each can of products shall be marked, affirmed, product title, production lot number, production unit title, location, production date. The tin cans are sealed and packed with a net weight of 20kg per can and are placed in a cool, airy, rigid place. Products in the transport should prevent rain, sunlight exposure, moisture intrusion and pay attention to sealing.
