PP覆塑模板的生产工艺的介绍

大家好，塑料与木材是完全不能结合的，今天我们来给大家讲一下，我们是如何把塑料和木材完美的粘接在一起。我们的这个想法来源于树皮为什么会粘在树干上，原因是因为我们仔细观察后发现，树干会有很多凸起的部分深入到树皮。首先我们参考这个原理，第一步，我们会在木材的表面打孔，在这个环节，如果覆塑模板板材生产过程有任何瑕疵，我们第一时间会筛选出来，第二步，我们优选高强度pp塑料，融化后流入板面，第三步，施加压力，将pp压入孔内，冷却后收缩，与木纤维抓在一起。在收缩的过程中，塑料会从220摄氏度降低到50摄氏度，在这个过程中，，塑料的收缩会产生很大的应力，如果胶合板的强度不够，很容易被拉开。所以，我们的生产过程，也是检验塑面模板胶合板的过程，任何不合格的胶合板都会从生产线淘汰。这也是我们质量稳定的原因之一。

Hi everyone, as you all know, plastic is not adhesive to wood. So today, I would like to talk about how we laminate plastic to wood seamlessly for the Rilico Plastic plywood. Our technology was developed from studying the tree barks. Why do tree barks sticks on the branches and trunks. It’s because the branches has fiber that extend into the bark, clinging them together tightly. Using this principal, we would first punch holes into the plywood, as this process will also test the strength of the plywood; we are able to pick out any defects. Second, we melt selected premium pp plastic and pour onto the surface of the plywood. Third, we apply pressure and push the melted plastic into the holes. As the plastic cools it contracts and clings onto the wood fiber. During this process, as the plastic goes from 220 degrees Celsius to 50, the contraction will create a tremendous force on the plywood; any defected plywood will de-laminate at this point. Hence, during the production the plywood has gone through several quality check points, any defects would be rejected immediately. This is one main reason why our quality is very stable and consistent. So please contact us if you are interested. Thanks for watching!
