PC耐力板的质量品质等级的辨别方法

来源:http://www.wanzhongyue.com/ 日期:2021-10-31 发布人:julong 浏览次数:

1、看PC耐力板的透明度,进口原料生产的聚碳酸酯(板材,是非常清澈透明的,比如3MM厚的透明耐力板,它的透光率为92%。8mm厚的透明耐力板的透光率则为83.3%,和玻璃差不多。
1. Looking at the transparency of PC endurance board, polycarbonate (plate) produced from imported raw materials is very clear and transparent. For example, the transmittance of 3mm thick transparent endurance board is 92%. The transmittance of 8mm thick transparent endurance board is 83.3%, which is similar to that of glass.
2、撕开pc板材表面的保护膜(Protective film),查看板材面是否平整,是否有气泡,颗粒。如果颗粒和气泡较大较多,则说明生产这批PC耐力板的原料较差,属于低档板。
2. Tear off the protective film on the surface of the PC board and check whether the board surface is flat and whether there are bubbles and particles. If there are large particles and bubbles, it indicates that the raw materials for the production of this batch of PC endurance board are poor and belong to low-grade board.
3、测量PC耐力板的实际厚度,正规的耐力板厂家在生产的时候,会将板材的厚度控制在国家标准的公差范围内,也就是客户订购3mm的pc耐力板,当拿到手之后,板材的厚度就是3mm足厚的。反之,则为质量较差的或则偷工减料的工厂生产的。

3. Measure the actual thickness of PC endurance board. When normal endurance board manufacturers produce, they will control the thickness of the board within the tolerance range of national standards, that is, when customers order 3mm PC endurance board, when they get it, the thickness of the board is 3mm thick. On the contrary, it is produced by poor quality or shoddy factories.
4、有条件的话,还可以用小块耐力板进行测试,用打火机将它点燃,质量较好PC原料生产的耐力板会在离开火源时自己熄灭。PC原料分子量较高,这种板材才不容易折断和破碎。
4. If possible, you can also use a small piece of endurance board to test and ignite it with a lighter. The endurance board produced by PC raw materials with good quality will extinguish itself when leaving the fire source. The molecular weight of PC raw materials is high, so this kind of board is not easy to break and break.
