石塑电梯门套的环保指标要注意什么?
一、认准厂名、厂址、商标是否真实
1、 Identify whether the factory name, address and trademark are true
如今的石塑电梯门套市场上,有的生产厂家,有的则是倒货的小公司,因此只有自己有工厂,有资质的厂家才是正规的,生产的石塑电梯门套产品质量才有保障。
In today's stone plastic elevator door pocket market, some manufacturers and some small companies pour goods. Therefore, only qualified manufacturers with their own factories are regular, and the quality of stone plastic elevator door pocket products can be guaranteed.
二、表面光滑程度。
2、 Surface smoothness.
石塑电梯门套表面应平整干净、无毛刺沟痕或者划痕。无透胶现象,板面无局部发黄、发黑等情况的出现。
The surface of stone plastic elevator door pocket shall be flat and clean without burr, groove mark or scratch. There is no glue penetration, and there is no local yellowing or blackening on the board surface.
三、分辨膜纸质量。
3、 Distinguish the quality of film paper.
一般情况下正规厂家采用的石塑电梯门套膜纸都是带有UV漆的,纹理图案有规则,防划耐磨,耐腐蚀,而质量差,环保不达标的石塑电梯门套,表面纹理图案会无规则,变异性比较大。
In general, the stone plastic elevator door cover film paper adopted by regular manufacturers is with UV paint. The texture pattern is regular, scratch resistant, wear-resistant and corrosion-resistant. For the stone plastic elevator door cover with poor quality and environmental protection, the surface texture pattern will be irregular and have great variability.
四、无起泡、裂缝现象。
4、 No bubbles and cracks.
在选择石塑电梯门套时仔细观察,在膜纸与基材之间的附着度、基材内部各层之间不能有严重的起泡、裂纹的情况。
When selecting the stone plastic elevator door pocket, carefully observe the adhesion between the film paper and the substrate, and there shall be no serious blistering and crack between the layers inside the substrate.
五、无刺激性气味。
5、 No pungent smell.
石塑电梯门套在选购时,可从气味来判断,如果没有明显的刺激性气味,一般都是符合环保标准的。
When purchasing stone plastic elevator door pocket, it can be judged from the smell. If there is no obvious pungent smell, it generally meets the environmental protection standard.
六、注意原材料比例
6、 Pay attention to the proportion of raw materials
石塑电梯门套原材料比例是质量的根本保障,因此原材料也决定了石塑电梯门套的环保指标,这个可以根据厂家讲解的钙粉、pvc树脂粉、化工小料的用量来判断。
The proportion of raw materials of stone plastic elevator door pocket is the fundamental guarantee of quality, so the raw materials also determine the environmental protection index of stone plastic elevator door pocket. This can be judged according to the amount of calcium powder, PVC resin powder and chemical small materials explained by the manufacturer.
