Quality Problems Easily Caused by Putty Scraping at the Edge of Plywood

胶合板边部刮腻子容易产生的质量问题

胶合板边部刮腻子是很多的内销和出口生产厂家中常见的一个生产工序,边部刮腻子,不仅可以使边部的离芯和缺层隐藏起来,也可以使边部的层次更加清晰。当然,边部刮腻子也有很多潜在的质量风险,比如质检员很难再发现边部的质量问题,如开胶,缺层,内部的结构和单板质量等。如果是冬季或者寒冷的季节,腻子被冻干了,含水率很难被检测准确,即使在夏季,如果腻子刮多了,也容易使边部产生开胶或者其它的质量问题。

Putty scraping at the edge of plywood is a common production process in many domestic and export manufacturers. Putty scraping at the edge can not only hide the core voids ,gaps and veneer missing defects at the edge, but also make the layer of the edge clearer and nice . Of course, there are many potential quality risks for edge-scraping putty, such as quality inspectors can hardly find edge quality problems again, such as delamination, lack of  veneer layers, internal structure and veneer quality. If it is winter or cold season, putty is freeze-dried, moisture content is difficult to be detected accurately, even in summer, if the putty scrapes too much, it is easy to cause delamination or other quality problems at the edge.
