挤塑板厂家对产品应用概述

第一,去皮处理。普通挤塑板表皮为光面,其表皮与胶粘剂及抹面砂浆的可粘接性很差。一方面可使表面粗糙均匀有利粘贴,其与胶粘剂和抹面砂浆的拉伸黏结强度、耐水和耐冻融强度均在0.25MPa以上,大大提高了系统的黏结力,加大了可靠性。另一方面也通过去皮处理均匀释放了一定量的内部应力。

First, skin treatment. The surface of ordinary extruded sheet is smooth, and its skin is poor in adhesion to adhesives and plaster mortar. On the one hand, the surface roughness and uniform bonding can be made. The tensile bond strength, water resistance and freezing thawing strength of the adhesive and the plastering mortar are above 0.25MPa, which greatly improves the bonding force and increases the reliability of the system. On the other hand, a certain amount of internal stress is released by peeling.

第二,国标情况。挤塑板的应用还没有一本国家的有关标准。由此多少应用方都借用膨胀聚苯板的技术标准。
Second, the status of the national standard. There is no national standard for the application of extruded panels. So many application parties borrow the technical standard of expanded polystyrene board.
第三,尺寸稳定性。行业里多认为挤塑板用于外墙外保温由于尺寸稳定性差,会因气候的影响而导致其尺寸变形,最终导致饰面层涂料开裂,不如EPS系统。实际上我们可以从系统中的三种材料的弹性模量来看,砂浆约为15500MPa,EPS约为4~6MPa,XPS约为7~9MPa。虽然EPS弹性模量比XPS略小,但与砂浆弹性模量相比,EPS与XPS挤塑板都属于同一数量级,材料相互之间的约束不会有本质的改变。
Third, dimensional stability. In the industry, it is believed that the Extrusion board used for exterior wall insulation because of the poor dimensional stability will cause its size deion because of the influence of the climate, and eventually lead to the cracking of the coating coating, which is not as good as the EPS system. In fact, we can see from the elastic modulus of the three materials in the system, the mortar is about 15500MPa, the EPS is about 4 ~ 6MPa, and the XPS is about 7 ~ 9MPa. Although the modulus of elasticity of EPS is slightly smaller than that of XPS, compared with the elastic modulus of mortar, both EPS and XPS Extrusion board are of the same order of magnitude, and the constraints between the materials will not be essentially changed.
