Fire retardant coating for steel structure
1 general design requirements for the thickness of the fire test to achieve the fire resistance limit thickness of 1.2 times, to the fire resistance limit for beam 2hour, column 3hour, the design thickness of beam 30mm, column 35mm. The first layer of thick 1cm or so, dry seven ~ 80% and then spray the layer, the layer thickness of about 1 ~ 1.2cm is appropriate, dry air from seven to 80% and then spray the third layer, the third layer to achieve the required thickness of up to second.
2 spray gun should be perpendicular to the sprayed steel components, the distance from 6 to 10cm is appropriate, spraying air pressure should be maintained at 0.4 ~ 0.6MPa, after spraying to carry out self inspection, the thickness of the part of the spray again.
The 3 Official spraying, spraying test of a construction zone (above), the fire department, quality supervision station personnel qualified after a large area of work.
4 when the construction environment temperature is lower than +5 DEG C, it shall not be constructed, and it should be taken to close the periphery, heating measures, the construction of 48hour before and after the maintenance of more than +5 DEG C is appropriate.
