挤塑保温板热解是在吸收良好的自由基

来源:http://www.sdyingxu.com/news/35.html 发布时间:2017-04-03

挤塑保温板热解过程中,火不燃酚醛树脂苯酚分子抗性是在吸收了良好的自由基。
In the pyrolysis process of extruded insulation board, the molecular resistance of phenolic resin was not good.
由一个支撑桥由苯酚分子和组织反应迅速吸收的断裂产生的自由基继续和高温火焰燃烧的情况下酚醛泡沫体,外观迅速以形成碳结构,有效地防止火焰的蔓延,以保持气泡结构中的主体。
Broken by a support bridge from phenol molecules and tissue reaction of free radicals to the rapid absorption and high temperature flame under the condition of phenolic foam, the appearance of rapidly to form carbon structure, effectively prevent the spread of flame, to maintain the main structure of the bubble.
伯恩斯收缩,滴,熔化,不变形,不可燃,氧指数可达50通过在树脂和发泡过程控制的改进,水平燃烧可以达到规范的程度。
Burns shrinks, drops, melts, does not deform, is nonflammable, oxygen index up to 50 through the improvement of the control of the resin and foaming process, the level of combustion can be achieved to the extent of the specification.

GPES保温板
基本结构的因素。框架结构墙接缝处混凝土梁和砖石,容易造成砌体变形绝缘损坏。
Basic structural factors. Frame structure wall joints of concrete beams and masonry, easy to cause masonry deformation insulation damage.
脚手架孔没有砌砖或结石,如局部形成绝缘基层摇摇晃晃和破坏建设。
Scaffolding hole without brick or stone, such as the formation of local grassroots rickety construction and destruction of insulation.
外墙装饰构件,移位,形成推拉,后局部空鼓保温层,抗裂渗水很长一段时间,最终导致保温层脱落。
Exterior decorative elements, formed after the shift, push and pull, local Konggu insulation layer, anti crack seepage in a long period of time, resulting in falling insulation.
