电缆沟阻火包-2017最新【防火包】价格表

在电力、通信、建筑等行业的电缆敷设工程中，电缆沟、竖井、桥架等部位的防火封堵是保障安全运行的关键环节。阻火包（俗称防火包）作为一种高效、灵活的防火封堵材料，被广泛应用于这些区域，用以阻止火焰和烟雾沿电缆通道蔓延。本文汇总了2017年市场上常见阻火包产品的参考价格，供工程设计、采购及施工人员参考。

一、什么是电缆沟阻火包（防火包）？

电缆沟阻火包是将无机耐火材料、膨胀材料等填充于特制的袋体中，形成一定规格的包状产品。遇火时，包内材料迅速膨胀，形成致密的防火隔热层，有效封堵孔隙，阻止火焰穿透。其使用简便，可根据封堵尺寸叠加堆砌，适用于不规则的孔洞和变动频繁的电缆通道。

二、影响2017年阻火包价格的主要因素

l 材质：如膨胀蛭石、珍珠岩、耐火纤维等原料品质影响成本。
l 规格尺寸：常见有320×120×60mm、400×200×60mm等，尺寸越大价格越高。
l 耐火极限：需达GB 23864-2009标准，高等级耐火时间相对昂贵。
l 采购数量：批量采购可获更多折扣。
l 地区与品牌：生产地、运输费用以及不同品牌溢价都在起作用。
