Intumescent fireproof sealant
|Product Name||Intumescent fireproof sealant|
|Specification Model||25 pcs/box|
|Product Advantages||The volume expands more than 5 times in fire, has good flexibility and adhesion, and forms a dense network structure after burning in fire; it can effectively prevent flame and heat transfer; high efficiency flame retardant, convenient construction|
|Scope of Application||1. Surface sealing of displaced floor slab gaps, wall caulking, mechanical pipes, ventilation pipes, thermal insulation pipes, etc. 2. Fireproof coating board to seal gaps; joints between wall tops and floor slabs; 3. Plastic pipelines (≤50mm) the gap of the penetration; the gap of the penetration of the HVAC duct|
Generally, the fire sealant is tested by vertical method. According to the test effect, it can be divided into FV-0, Fv-1 and Fv-2 from high to low. It is mainly used for the sealing of curtain wall fireproof structure, and it needs the ability of anti displacement deformation and fire and smoke prevention, Acrylic acid fire-proof sealant is compatible with gun type. The fire-proof sealant concept measure type fire-proof material is a kind of polymer plastic sealing material for plugging, which has the dual performance of sealing and fire-proof, and is suitable for fire-proof construction. The construction scope includes metal pipes, heat-insulating pipes and building joints. The adhesive strips used on the fire-proof doors of fire-proof sealant express can not meet the fire-proof requirements, Visually check that there are no small white spots of non combustible materials on the rubber strips. If you use a lighter to light them, what's more, if you simply do not install sealant strips, the fire prevention and smoke isolation function of steel fire doors is seriously affected.
The fireproof sealant is suitable for the joint construction between ceiling and wall body, especially for the longer joint. Because the spraying construction is simple, it can save manpower and reduce cost during construction. After being cleaned with water, it can be completely cured and painted. The maximum width of fire resistance joint can be 6 inches, and the fire resistance efficiency of joint position can be up to 2 hours.
