为什么防火板会出现开胶的现象?

来源:http://www.fumeijia.net/ 日期:2021-02-01
   防火板生产厂家所生产的产品在生活总扮演着十分重要的角色,但是在使用的过程中,会出现开裂的现象,那么这是什么原因所导致的呢。
The products produced by fireproof board manufacturers always play a very important role in life, but in the process of use, there will be cracks, so what causes this.
其实防火板会出现这种开胶的现象还是经常能够见到的,会出现这种情况,主要是因为吸水率的问题所造成的,如果大于一定的标准,那么防火板就会出现开胶的现象。其次就是有关吸水膨胀率的现象,吸水膨胀率要小于百分之四,如果防火板的吸水膨胀率不能达到它的使用要求,所以也是会出现开胶的现象的,还有一个原因就是防火板所使用的胶太少所造成的,呈现分层。

In fact, the phenomenon of opening glue is often seen in fireproof board, which is mainly caused by the problem of water absorption. If it is greater than a certain standard, the phenomenon of opening glue will appear in fireproof board. The second is about the phenomenon of water swelling rate. The water swelling rate is less than 4%. If the water swelling rate of the fireproof board can't meet its use requirements, the phenomenon of glue opening will also appear. Another reason is that the glue used in the fireproof board is too little, resulting in delamination.
另外,如果防火板在热压时,没有压组成一体,在拆模或许运用中就会出现膜纸分层,了解了相关原因,我们可以对症下药,购买合格的产品。
In addition, if the fire-proof board is not pressed as a whole during hot pressing, lamination of membrane paper may appear during formwork removal and application. After understanding the relevant reasons, we can suit the remedy to the case and purchase qualified products.
