挤塑板对于生产时的质量要求
作者:admin 来源:本站 发布时间:2016-12-07 18:23:51 浏览次数:314
表面处理:产品表面平整,无夹杂物,颜色均匀。不应有影响使用的可见缺陷,如起泡,裂口,变形等。
Surface treatment: the product surface is smooth, no inclusions, color uniformity. There should be no impact on the use of visible defects such as bubbles, cracks, deion, etc..
实际工程应用中,某些品牌的挤塑板平整度欠佳,影响施工质量。
In the practical application, the poor smoothness of some brands of plastic extruded board, affecting the quality of construction.
标准建议:对外墙用挤塑板平整度指标可以参照行业标准JG 149-2003 中EPS板的平整度允许偏差。

The standard advice: the smoothness of the allowable deviation of wall roughness index can be extruded board according to the industry standard JG 149 - 2003 EPS plate.

国内厂家实际标准:受成本和技术能力制约,比较忽视阻燃性问题。
The actual standard of domestic manufacturers: the cost and technical capacity constraints, the more ignored the problem of flame retardant.
实际工程应用中,有大量非阻燃型挤塑板。
In practical applications, there are a lot of non flame retardant plastic extruded board.
标准建议:制定标准等级,严禁使用非阻燃挤塑板。
The standard recommended standard grade, prohibited the use of non flame retardant plastic extruded board.
湿性能:实际工程应用,有设计人员提出挤塑板透气性太差而选用聚苯板。外墙用EPS的水蒸汽透过系数值在4.5左右,通过打磨处理或不带皮的XPS板的水蒸汽透过系数值能达到3.5左右。
Wet performance: the actual project application, designers put forward extrusion plate permeability poor selection of polystyrene board. The water vapor transmission coefficient of EPS in the external wall is about 4.5, and the water vapor transmission system of the XPS board which is processed by grinding or without skin can reach about 3.5.
建议使用标准:建议使用打磨板或经过表面处理的挤塑板,可略提高透气性。。
Recommended standard: it is recommended to use the grinding plate or extruded plate after surface treatment, can slightly improve the permeability..
