  • 防火门选购的方法
  • 本站编辑:杭州狮王门业有限公司发布日期:2019-10-24 08:06 浏览次数:


  选购优质防火门有五大招:
  第一招是查外观,优质钢质\防火门焊接牢固,焊点分布均匀;外表面喷涂平整光滑;在规定的位置应有产品标志、质量检验合格标志和质量认证(认可)合格标志。而合格的木质防火门外观应完整,无破损,表面净光,无刨痕、毛刺和锤印;割角、拼缝应严实平整。
  第二招是对数字,合格产品的外形尺寸应小于等于样品描述中的外形尺寸,门扇厚度应大于等于样品描述中的门扇厚度,门框侧壁宽度应大于等于样品描述中的门框侧壁宽度,防火玻璃外形尺寸应小于等于样品描述中的防火玻璃外形尺寸,防火玻璃厚度应大于等于样品描述中的防火玻璃厚度。
  第三招是看封条,合格的钢、木质防火门应设置防火密封条,该密封条应平直、无拱起,并有国家级检测机构出具的合格检测报告。
  第四招是估重量,质量合格的防火门一般较重,而那些很轻的防火门肯定是质量伪劣的产品。
  第五招是查证书,防火门是纳入型式认可制度的产品,产品在销售前都需要进行型式检验,一般型式检验报告中都详细描述了样品的规格尺寸、组成、材料以及产品的照片等,在实际购买时,需向厂家索取型式检验报告

There are five ways to purchase high-quality fire doors:            The first method is to check the appearance. The high-quality steel / fire door shall be firmly welded and the welding points shall be evenly distributed; the external surface shall be painted flat and smooth; the product mark, quality inspection mark and quality certification (APPROVAL) mark shall be provided at the specified position. The qualified wooden fireproof door shall be complete without damage, with clean surface, no planed mark, burr and hammer mark; the corner cutting and joint shall be tight and flat.            The second method is to use numbers. The overall dimension of qualified products shall be less than or equal to the overall dimension in the sample description, the door leaf thickness shall be greater than or equal to the door leaf thickness in the sample description, the door frame side wall width shall be greater than or equal to the door frame side wall width in the sample description, the overall dimension of fire-proof glass shall be less than or equal to the overall dimension of fire-proof glass in the sample description, and the fire-proof glass thickness shall be greater than or equal to The thickness of the fireproof glass in the sample description.            The third method is to look at the sealing strip. The qualified steel and wood fire doors shall be provided with fire sealing strip, which shall be straight and free of arching, and shall have the qualified test report issued by the national testing agency.            The fourth method is to estimate the weight. Generally, the fire doors with qualified quality are heavier, while those with very light quality must be fake products.            The fifth call is to check the certificate. The fire door is a product incorporated into the type approval system. The type inspection is required before the product is sold. The general type inspection report describes the specification, size, composition, material and product photos of the sample in detail. When actually purchasing, the type inspection report shall be obtained from the manufacturer.
