THB-720阻火包

THB-720阻火包，外包由編織緊密經特殊處理的玻璃纖維布制成，包內填充不燃材料及特殊添加劑和相應助料，具有不燃性和良好的耐候性，且施工方便，遇火時包內物體迅速膨脹，形成嚴密的防火堵層，達到阻止燃燒的目的。適用于電纜貫穿的孔洞封堵及構筑阻火墻，阻火段等。特別適用于電纜頻繁變更部位，可作臨時或永久性封堵。

THB-720 fire retardant package, outsourcing by tightly woven by spe cial treatment of glass fibercloth made, bag filed with non flammable materials and special additives and the correspondingauxiliary material, with non flammable and good weather resistance and is convenient for construction,in case of fire within the package object expands rapidly, forming a strict anti fire blocking layer, toprevent burning. Application in cable through hole plugging and construction of fire retardant fireproofwall, etc.. The cable is especially suitable for frequent changes in position, can be used as a temporaryor permanent closure .

施工方法：

1.將需封孔洞中的電纜作必要的排列整理。
2.-般先在電纜周圍包裹有機防火堵料，再將阻火包平服地嵌入封堵部位。
3.阻火包應交叉堆疊、牢固、密封不透光為準。4.施工中阻火包應無破損。 

1.Cables in the holes which should be sealed should be arrangedand cleared up.

2.Organic fire-proof putty should be packed around cables usUally,and the fire-resistant pillow should be inset in the plugging part.

3.The fire-proof pillow should be cross piled, fastened, with astandard of sealing and light-proof.

4.The fire- proof pillow should not be broken in construction.
