2013-11-7 13:38:54
出现频率较高的品质不良现象,现在我们国家的该项产品的市场不是很好,有很多的劣质产品存在,其面对的隐患现象很多。通过分析几个区域安装的具体情况,我们发现防火卷帘门面对如下的一些不利现象。
Poor quality phenomenon of higher frequency, now our country the product market is not very good, there are many inferior products, in the face of danger phenomenon in many. Through the analysis of the specific situation of several regional installed, we found that the fire shutter doors facing some unfavorable phenomena as follows.
门帘厚度即帘板所用钢板的厚度,现在行业中经常性的存在偷工减料问题,一些商家在面对检测活动的时候,使用非常厚的材料,当获取了认可之后,就使用不一样的材料来制作,所以影响到它的品质。因为在场地之中,它的厚度是无法实际测定出来的,因此不容易辨别,就使得很多的劣质产品流通到市场中。所以,目前的许多的产品厚度都是不合格的,这就影响到救援工作的开展。
The thickness of the steel plate thickness is the curtain curtain plate, now in the industry often exist Jerry, some businesses in the face of the inspection activities, the use of very thick materials, after obtaining the approval, the use of different materials, so the impact of its quality. Because of the space, its thickness is not measured out, it is not easy to distinguish, makes a lot of inferior products circulation to the market. So, many of the current thickness of the product is unqualified, in which affect the rescue.
结合当前的规定,其应该设置门楣构造,现在运行的这些产品中,很多未为设置门楣。此,当火情发生的时候,其无法避免火势发展,就会在非常大的冲击力的影响下,使得烟气扩散。这个位置的密闭性是整个设计中非常关键的一个要素。假如使用这种产品的话,其根本的无法实现防火的功效。
According to the current provisions, it should set the lintel structure, now operating these products, many did not set the lintel. This, when the fire occurs, it can not avoid the influence of development, will be in a very large impact under, so that the flue gas diffusion. Closed this location is a very important factor in the design of the whole. If the use of this product, the basic can not realize the fire effect.
其深度不合理,构造以及使用的物质不合理,是目前很多产品在安装的时候,经常性的会面对的不利现象。正规的产品中在导轨处都应该有一个受力性非常高的构件,不过很多单位在制作的时候,都是用较轻的材料,如果出现火情的话,门帘就脱离出来,无法实现防火意义。
Its depth is not reasonable, structure and the use of the substance is not reasonable, is at present a lot of products at installation time, unfavorable phenomenon recurring will face. The regular products in the guide rail should have a very high stress components, but when many units in the production, are made of lighter materials, if the fire is out, the curtain, unable to realize the fire significance.
