在装修材料市场越秀中路一家卖防盗门的店铺，一位老板娘模样的女士介绍了一款东×牌的钢塑门，“门的材质是钢板，里面的填充材料是‘高压聚氨酯发泡’，能防火隔音，一扇门1880元。”在另一家店，店主也介绍一款钢板门，说填充材料是“防火泡沫”，“耐火半个小时左右”，售价1480元。不过这些店铺都表示没有防火证提供。
“我们这里的门填充料是岩棉，都有防火证，耐火时间能达到72分钟”，在第三家×家牌的专卖店，销售经理说，他们有防火功能的产品都取得了防火证，一款有防火功能的“乙级防盗安全门”，价格是2680元，没有防火功能的“丁级防盗安全门”，价格为1800元，相差880元。
“高压聚氨酯发泡根本起不到防火的作用”，广州市质量监督检测研究院建材消防检验部部长何国山告诉笔者，所谓“高压聚氨酯发泡”本身很容易着火，即使加了阻燃剂，也满足不了真正的防火需求，“聚氨酯就是冰箱门的泡沫，只能起保温作用”。
何国山说，如果防盗门要添加防火的功能，那么必须同时符合防盗和防火两个国家标准，“目前我还没有看到真正的有防火功能的防盗门。”
“好的防火门一般采用硅酸铝纤维或岩棉作填充材料，或者选用密度较大的其他耐火材料。但这些耐火材料又常是火灾毒烟的源头，因此我们只能选择产烟毒性低的材料”。
“一般来说，家居用门防火意义不大”，何国山指出，即使防盗门真正能防火，也要取得“防火证”和耐火极限的检测报告，成本要数万元。这对于普通厂家来说是很高的成本，“所以市面上很少有真正既防盗又防火的产品。”
何国山说，要判断产品是否真的能防火必须通过检测，肉眼无法判断，“防火证和检测报告都有编号，可以通过检测中心的号码查询真伪。”
Yuexiu Road in the decoration materials market, a shop selling security doors, look like a lady boss wife introduced a brand of steel-plastic door east × "material is a steel door, which the filler material is ’high-pressure polyurethane foam’ to fire insulation, a door 1880 yuan. "In other stores, shopkeepers also introduced a steel door, said filling material is" fire bubble "" fire about half an hour ", price 1480 yuan. However, these shops have provided evidence that there was no fire.
"Filler door here is mineral wool, have fire certificate, the time to achieve 72 minutes fire resistance", in the third × home store cards, sales manager, said they have fire safety features of the products have made fire safety certificate fire prevention function of a "B anti-theft security door", the price is 2680 yuan, there is no fire protection features, "D-class anti-theft security door" price of 1,800 yuan, a difference of 880 yuan.
"High-pressure polyurethane foam will not achieve the fundamental role of fire", Guangzhou Institute of Quality Supervision and Testing Laboratory Building Fire Minister of State Hill told reporters how the so-called "high-pressure polyurethane foam" itself is very easy to ignite, even if the addition of flame retardants, but also can not meet the needs of real fire, "is the refrigerator door polyurethane foam insulation can only play a role."
Ho Shan State said that if the security doors to add fire safety feature, you must also comply with security and fire safety standards for both countries, "I have not seen a real capabilities of the security door with fire."
"Good fire doors generally use ceramic fiber or mineral wool as filling material, or other high density refractory materials used. But these refractories were often the source of fire, toxic smoke, so we can only choose the low toxicity of smoke material. "
"In general, home fire doors not meaningful," said Ho Shan State, even if the security doors can really fire, but also to obtain "fire certificate" and the fire resistance test report, the cost to several million. This is very high for the average factory costs, "so the market has little real alarm fire both products."
He said the country mountain, to determine whether the product really must fire detection, the naked eye can not tell, "fire certificate and test report numbered, you can check the authenticity test center number."
