PP覆塑模板的生產工藝的介紹
大家好，塑料與木材是完全不能結合的，今天我們來給大家講一下，我們是如何把塑料和木材完美的粘接在一起。我們的這個想法來源于樹皮為什么會粘在樹干上，原因是因為我們仔細觀察后發(fā)現(xiàn)，樹干會有很多凸起的部分深入到樹皮。首先我們參考這個原理，第一步，我們會在木材的表面打孔，在這個環(huán)節(jié)，如果覆塑模板板材生產過程有任何瑕疵，我們第一時間會篩選出來，第二步，我們優(yōu)選高強度pp塑料，融化后流入板面，第三步，施加壓力，將pp壓入孔內，冷卻后收縮，與木纖維抓在一起。在收縮的過程中，塑料會從220攝氏度降低到50攝氏度，在這個過程中，，塑料的收縮會產生很大的應力，如果膠合板的強度不夠，很容易被拉開。所以，我們的生產過程，也是檢驗塑面模板膠合板的過程，任何不合格的膠合板都會從生產線淘汰。這也是我們質量穩(wěn)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!
