Description
[technical field]
The present invention relates to the smoke exhaust fan that fire-fighting is used, particularly relate to the fire prevention processing method that smoke exhaust fan is used in a kind of fire-fighting.
[background technology]
Fire-fighting is widely used in the place that office block, hotel, restaurant, cinema, market, hospital, underground parking etc. need anti-smoke evacuation with smoke control system.Existing blower fan for anti-smoke evacuation, airduct, air-valve etc. are many to be made with steel plate or galvanized steel plain sheet, and not mineral wool protection processing of this kind equipment self, does not therefore have fire-proof function.A large amount of scientific research data both domestic and external and fire cases show that there are not the risk that collapses, is out of shape, damages in the airduct of mineral wool protection, blower fan, air-valve etc. in standing fire process, and the damage of equipment then can cause fire and flue gas to spread.So under normal conditions, blower fan, air-valve, the airduct of mineral wool protection do not have desired fire resistance.
Although the fire-resistant requirement of blower fan, airduct etc. that relevant fire prevention standard is clear and definite, but the fire prevention measure of this kind equipment mainly is to construct the fire prevention insulating space in the equipment installation position at present, as adopt hard moulding PLASTIC LAMINATED (as glass magnesium PLASTIC LAMINATED) parcel to isolate, wherein, blower fan is adopted the moulding PLASTIC LAMINATED, construct enclosure space, form parcel in blower fan is installed in and isolate, in fact be equivalent to construct Ventilator Room in the blower fan periphery with PLASTIC LAMINATED.Though this method can play anti-fire action, because this method should take a large amount of confined spaces, be difficult to guarantee ceiling height again, the interface of its seam crossing is handled and also is difficult to guarantee, causes constructional difficulties, and with high costs.Also there are same problem in airduct and air-valve, and the size that it is fixing and the plasticity of extreme difference cause difficulty of construction big, and material, cost of labor are higher.The another kind of method that adopts is with soft anti-guncotton felt class parcel at present, though this method can sturdy equipment surface be installed, it is more convenient to install, and fire resistance is better, but adopt qualified fire-resistant cotton felt can cause installation cost to improve, and be difficult to whole coverings for irregular edge.In addition, more then be not to use the person to ignore pertinent regulations and clear-cut directly exposed the installation, thereby bury potential safety hazard.
[summary of the invention]
The present invention is intended to address the above problem, and provide a kind of directly to the smoke exhaust fan processing of preventing fires, the processing procedure simple and fast, smoke exhaust fan after the processing can directly be installed and used because possessing fire protecting performance, and can save big quantity space and floor space, and fire resistance is reliable and stable, and is with low cost, the fire prevention processing method of the smoke exhaust fan that aesthetic property is good.
For achieving the above object, the invention provides the fire prevention processing method that smoke exhaust fan is used in a kind of fire-fighting, this method comprises the steps:
The outer surface of a, the smoke exhaust fan used in fire-fighting applies one deck antirust paint;
B, at dried antirust paint surface-coated one deck fireproof paint at least, form the fireprotection layer that flameproof protection is used;
C, apply one deck finish paint at the outer surface of dried described fireprotection layer, finish the fire prevention of smoke exhaust fan after oven dry or the air dry and handle.
Among the step b, described fireproof paint is fire-resistant coating for steel structure.
Described fireproof paint is thick formed steel construction fireproof paint, thin section steel structure fire-resisting paint or super-thin steel structure fire-proof paint.
