    门帘加工选材问题 你了解多少?

    在门帘加工中,重要的就是选材问题,下面,我们一起了解一下门帘加工的选材问题:
    In the process of curtain processing, the important thing is the selection of materials. Let's learn about the selection of materials for curtain processing:
    a.帘面的受火面材料,应选用使用温度达到1100℃的材料,而现在有些厂家选用的是使用温度低于1000℃的材料,甚至用耐火而不防火的硅酸铝纤维布做受火面材料,不能保证使用的安全性;

    a. The material of the fire receiving surface of the curtain surface should be the material with the use temperature reaching 1100 ℃, while now some manufacturers choose the material with the use temperature lower than 1000 ℃, or even use the fire-resistant but not fireproof aluminum silicate fiber cloth as the fire receiving surface material, which can not guarantee the safety of use;

    b.帘面的防热辐射布,有的厂家取消了这一层,并没有相应增加隔热层或空气层的厚度,使防火卷帘的总隔热能力降低;
    b. Some manufacturers cancel this layer of the heat radiation proof cloth on the curtain surface, but do not increase the thickness of the heat insulation layer or the air layer correspondingly, so that the total heat insulation capacity of the fire rolling curtain is reduced;
    c.帘面的中间隔热层,有的产品没有足够的厚度;
    c、 The insulation layer in the middle of the curtain surface, some products do not have enough thickness;
    d.帘面的饰面材料,有的采用一般阻燃布,不防火,不耐火,不耐磨,使用寿命短;
    d. Facing materials of curtain surface, some of which are made of general flame-retardant cloth, are not fireproof, fire-resistant, wear-resistant and have short service life;
    e.帘面的缝纫线,有的厂家在缝制帘面中使用普通的或中缝纫线,而未选用耐高温的缝纫线.使帘面在火灾作用时容易散架脱线,不能使帘面充分发挥防火隔热性能;
    e. For the sewing thread on the curtain surface, some manufacturers use ordinary or medium sewing thread instead of high-temperature resistant sewing thread, so that the curtain surface is easy to fall apart in case of fire, and the curtain surface can not fully play the role of fire and heat insulation;
    f.帘面中的增强钢丝绳,它会因逐渐锈蚀影响防火卷帘的使用寿命.
    f. The reinforced steel wire rope in the curtain surface will affect the service life of the fire shutter due to the gradual corrosion
