ZHQ建筑排水PVC-U管阻火圈 ZHQ Buliding draining PVC-U pipe firestops collar
阻火圈,火災(zāi)發(fā)生時(shí),阻火該產(chǎn)品主要有金屬殼體和阻燃膨脹芯材組成,使用時(shí)將阻火圈套在硬聚氯乙烯管的外壁,固定在樓板或墻體部位,圈內(nèi)的芯材受熱急速膨脹,擠壓受熱變軟的PVC-U管道,在較短的時(shí)間內(nèi)封堵管道貫穿洞口,阻止火勢(shì)沿洞口蔓延至上一層樓或相鄰房間。經(jīng)國(guó)家防火建筑材料質(zhì)量監(jiān)督檢測(cè)中心檢測(cè),各項(xiàng)性能指標(biāo)符合要求,超過(guò)同類產(chǎn)品水平。
Firestops collar,ZHQ fire barrier ring is made up with metallic shell and inflaming retarding expansive core material When used the fire
barrier ring is fixed on the external face of PVC pipe Which is on the floor or wall When fire happens the core material of fire barrier ring expands quickly to extrude the PVC-U pipeline Which had been heated to become soft in the fire and the pipe will be sealed in a short time.So the fi re will be prevented from spreading to up-floor or next room The product has been tested by the National Fireproof Building
Material Quality Monitoring and Testing Center the results showed that the performance index of the ZHQ fire barrier ring accorded with the
de-mands,and better than the products of the same kind.
