Description
[technical field]
The present invention relates to the airduct that fire-fighting is used, particularly relate to the fire prevention processing method of the airduct that a kind of ventilation smoke exhaust uses.
[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, air-valve 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, construct enclosure space, form parcel in airduct etc. is installed in and isolate.Though this method can play anti-fire action, because the constructed enclosure space of this method should take certain space, job site, the processing of its interface also is difficult to guarantee, causes constructional difficulties, and with high costs.The fixing size of airduct 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 airduct processing of preventing fires, the processing procedure simple and fast, airduct 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 airduct that aesthetic property is good.
For achieving the above object, the invention provides the fire prevention processing method that airduct is used in a kind of fire-fighting, this method comprises the steps:
The outer surface of a, the airduct 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 airduct 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.
Thick formed steel construction fireproof paint is that coating layer thickness is the non-expansion type fire-resistant coating for steel structure of 7～50mm.
Thin section steel structure fire-resisting paint is that coating layer thickness is at the expansion steel-structure fireproofing coating of 3～7mm.
Super-thin steel structure fire-proof paint is the fire-resistant coating for steel structure that coating layer thickness is no more than 3mm.
The fire endurance of thick formed steel construction fireproof paint, thin section steel structure fire-resisting paint or super-thin steel structure fire-proof paint is 0.5～3 hour.
Thin section steel structure fire-resisting paint or super-thin steel structure fire-proof paint are one or more the combination in transparent fire-resisting paint, water-soluble fire-proof dilatation, phenolic aldehyde base fireproof paint, latex fire-proof paint, the basic fireproof paint of polyvinyl acetate breast, room temperature self-drying type water-solubility expanding fire-proof paint, polyolefin fire-proof insulation coating, the high chlorine polyethylene of modification fireproof paint, chlorinated rubber fire-proof dilatation, the intumescent coating.
Described antirust paint is sprayed at the outer surface of airduct with spraying equipment, and fireproof paint is sprayed at the antirust paint surface, and finish paint is sprayed at the fireproof paint surface.
Described airduct comprise the penetrate firewall subregion airduct, pass through cup and anti-smoke evacuation staircase airduct, be positioned at the airduct of corridor furred ceiling or close other combustible.
Contribution of the present invention is that it efficiently solves the fire safety problem of airduct.Method of the present invention can be directly to the airduct processing of preventing fires, by at airduct surface-coated fireproof paint, can form the fireprotection layer of fire resistance excellence, make it can stand 0.5～3 hour flame baking and can not damage, thereby refractory ability and the safety in utilization of airduct have greatly been improved, and because fire resistant coating is attached to the airduct surface, does not take installing space, thereby can save big quantity space and floor space.The processing procedure simple and fast of this method, its both can be at the construction field (site) to the airduct processing of preventing fires, also can be in factory processes after the manufacturing of airduct product is finished, airduct after the processing can directly be installed and used, and need not construct insulating space, and fire resistance is reliable and stable, with low cost, aesthetic property is good.The present invention can be widely used in the penetrate firewall subregion airduct, pass through cup and anti-smoke evacuation staircase airduct, be positioned at the corridor furred ceiling or near the fire prevention processing of the airduct of other combustible.
