普板挤塑板和阻燃板的本质区别
作者:admin 来源:本站 发布时间:2016-12-17 14:47:35 浏览次数:428
普板和阻燃板的最大区别是有没有添加阻燃剂,重量稍轻:阻燃板每方32公斤以上,普板只有28-31公斤左右。“阻燃剂的价格很高,阻燃板的成本因此也大幅度提高。”没加阻燃剂的普板阻燃效果不好,甚至可以说阻燃率为零。这种板子的价位比较便宜,每立方340元;有多种规格,2公分到10公分等多种型号,其价格不一样。
General board and flame retardant board is the biggest difference is not added flame retardant, weight slightly lighter: flame retardant board 32 kg each side, Pu board only about 28-31 kg. "The price of flame retardant is very high, so the cost of flame retardant board is greatly increased." No flame retardant general board flame retardant effect is not good, and even can be said that the flame retardant rate is zero. The price of this board is cheaper, 340 yuan per cubic meter; there are a variety of specifications, ranging from 2 cm to 10 cm and other models, the price is not the same.
阻燃板分B1、B2级,阻燃板对生产技术要求高,阻燃效果好,能有效保障施工安全,减少工程风险和损失,因此,国家建设部与公安部联合出台46号文规定,禁止非阻燃板上墙,因工程造价会增加,很多工程施工方铤而走险,才使得工程安全问题非常严峻。
In B1, B2 flame retardant, flame retardant in high demands on the production technology, good flame retardant effect, can effectively guarantee the safety of construction, reduce project risk and loss, therefore, the State Ministry of construction and the Ministry of Public Security jointly issued regulations No. 46, prohibit non flame retardant plate on the wall, because the project cost will increase, a lot of engineering construction collar desperate, makes the project safety problem is very serious.
按照国家标准,挤塑板名称就叫绝热用挤塑聚苯乙烯泡沫塑料,保温,阻燃、抗压、环保等功效是最重要的功能,现行的国家标准GB8624《建筑材料制品燃烧性能分级》规定:B2级是现在XPS挤塑板的最低阻燃要求氧指数≥26。根据《中华人民共和国消防法》第二十六条规定“建筑构件、建筑材料和室内装修、装饰材料的防火性能必须符合国家标准;没有国家标准的,必须符合行业标准。”的要求,挤塑板在生产过程中需要添加阻燃剂,以阻止和延缓聚苯乙烯板材的剧烈燃烧。
According to the national standard, extruded polystyrene foam board, plastic extruded board is called insulation, flame retardant, compressive strength, environmental protection effect is the most important function of the national standard GB8624 "building materials flammability classification" provisions: B2 is now the lowest of flame retardant XPS plastic extruded board requires oxygen index is more than 26. According to the "People's Republic of China Fire Law" twenty-sixth article "the fire performance of building components, building materials and interior decoration, decoration materials must comply with national standards; no national standards, must comply with industry standards." The requirements of extruded plate need to add flame retardants in the production process, the combustion preventing and delaying polystyrene plates.
