點擊圖片查看大圖阻火圈,該產(chǎn)品主要有金屬殼體和阻燃膨脹芯材組成，使用時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，火災發(fā)生時，阻火圈內(nèi)的芯材受熱急速膨脹，擠壓受熱變軟的PVC-U管道，在較短的時間內(nèi)封堵管道貫穿洞口，阻止火勢沿洞口蔓延至上一層樓或相鄰房間。經(jīng)國家防火建筑材料質(zhì)量監(jiān)督檢測中心檢測，各項性能指標符合要求，超過同類產(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.
