DB-A2-THB720膨胀型阻火包
DB-A2-THB720 Expanding Fire Protection Pillows
DB-A2-THB720膨胀型阻火包，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，具有不然性和良好的耐候性，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。
施工方法：
Job practice：
1．将需封孔洞中的电缆作必要的排列整理。
Cables in the holes which should be sealed should be
arranged and cleared up.
2．一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。
Organic fire-proof putty should be packed around cables
usually, and the fire-resistant pillow should be inset in the plugging part.
3．阻火包应交叉堆叠、牢固、密封不透光为准。
The fire-proof pillow should be cross piled, fastened,
with a standard of sealing and light-proof.
4．施工中阻火包应无破损。
The fire-proof pillow should not be broken in
construction.
