THB-720阻火包，外包由编织紧密经特殊处理的玻璃纤维布制成，包内填充不燃材料及特殊添加剂和相应助料，具有不燃性和良好的耐候性，且施工方便，遇火时包内物体迅速膨胀，形成严密的防火堵层，达到阻止燃烧的目的。适用于电缆贯穿的孔洞封堵及构筑阻火墙，阻火段等。特别适用于电缆频繁变更部位，可作临时或永久性封堵。

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.将需封孔洞中的电缆作必要的排列整理。
2.-般先在电缆周围包裹有机防火堵料，再将阻火包平服地嵌入封堵部位。
3.阻火包应交叉堆叠、牢固、密封不透光为准。4.施工中阻火包应无破损。 

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.
