劣质挤塑板的危害是什么
What are the hazards of inferior Extrusion board
优质的挤出板原料纯聚苯乙烯。即使在高温下也不会释放有害气体。TVOC释放量和游离苯含量均为零。
Pure polystyrene is the raw material of high quality extrusion board. It does not release harmful gases even at high temperatures. Both TVOC release and free benzene content were zero.

Attachment: Environmental protection test report. (Two test data enlargement)
下挤板由回收的泡沫塑料制成,如塑料饭盒。可疑杂质含量高。成品有异味。
The lower extrusion board is made of recycled foam plastics, such as plastic lunch boxes. Suspicious impurity content is high. The finished product smells bad.
二世。低质量的挤压板密度低,抗压性差,甚至小于100KPA。易引起地面开裂变形。
II. Low quality extruded sheet has low density and poor compressive resistance, even less than 100KPA. It is easy to cause ground cracking and deion.

Ground cracking caused by inferior Extrusion board
好的挤出板每平方米的压力在20吨以上。确保使用寿命与建筑物相同。

The pressure of good Extrusion board is more than 20 tons per square meter. Make sure the service life is the same as that of the building.

三、劣质挤出板含有大量杂质。由于毛细作用的存在,在使用过程中含水率会逐渐增加。一方面,这将导致挤压板绝缘效果线性下降。另一方面,潮湿的环境为霉菌的生长创造了条件。危及你和你的家人。
3. The inferior Extrusion board contains a lot of impurities. Because of the existence of capillarity, the water content will gradually increase in the use process. On the one hand, this will lead to a linear decline in the insulation effect of extruded sheets. On the other hand, the humid environment created conditions for the growth of fungi. Endanger you and your family.

挤压板具有闭孔结构。它不吸水。良好的保温效果。
The extrusion plate has a closed-hole structure. It does not absorb water. Good thermal insulation effect.
据国外资料显示,地面热损失占总热量的25% ~ 30%。
According to foreign data, surface heat loss accounts for 25% to 30% of total heat.
即使使用很长时间,挤出板的导热系数也能保持不变。低质量的挤压板导热系数高,随着时间的推移会逐渐失去保温效果。地板采暖的运行成本将逐步消失。
The thermal conductivity of the extruder can remain unchanged even if it is used for a long time. Low quality extruded sheets have high thermal conductivity, which will gradually lose the thermal insulation effect over time. The operating cost of floor heating will gradually disappear.
