由四川省建材工业科研所研制、成都金属门窗厂试制生产的“FH 系列无机复合防火门”最近研制成功。该类产品是采用粘接材料,增强材料和外加剂等,按一定的重量百分比,制成符合防火门扇要求的各型板材,再经复合装修而成。它的主要优点为:1.耐火,抗热震性强,耐火极限高。经测试该类产品耐火极限达到目前防火门甲级标准:72分钟,向火面达1000—1100℃,背火面最高测温点82℃,燃烧后完整无缺。其耐火性能明显优于钢、木质防火门;
The “FH Series Inorganic Composite Fire Door” developed by Sichuan Institute of Building Materials Industry Research and Chengdu Metal Door and Window Factory has been successfully developed. This type of product is made of adhesive materials, reinforcing materials and admixtures, etc. It is made of various types of plates that meet the requirements of fireproof doors and doors according to a certain percentage of weight, and is then decorated by composites. Its main advantages are: 1. Fire resistance, thermal shock resistance, high fire resistance. After testing, the fire resistance limit of this type of product reaches the current fire door class A standard: 72 minutes, the fire surface reaches 1000-1100°C, and the highest temperature measurement point of back fire surface is 82°C, and it is intact after burning. Its fire resistance is obviously superior to steel and wood fire doors;
