当社会水平一直在不断的提升与发展,桦木胶合板这一产品是常运用的装修材料,桦木胶合板主要是采用原木旋切成单板,或者木方刨切成薄木,再用胶粘剂胶合而成的三层或三层以上的薄板材。
When the social level has been continuously improved and developed, birch plywood is a commonly used decoration material. Birch plywood is mainly made of logs that are peeled into veneers, or wood squares are sliced into thin wood, and then glued with adhesives. Thin plates with three or more layers.
同时每个单片的含水率胶合板要求也是比较严格的,假定过高就较易发生脱胶现象,过低原子中的羟基活性下降,使得物理机能也会受到影响,因此要根据标准进行严格把关,保证给顾客出产合格的产品。
还有一个重要的政策便是甲醛的开释量要合格。桦木胶合板的甲醛释放量大大都都来源于所用胶粘剂产品,因此胶粘剂甲醛释放量是否合格是点评
桦木胶合板是否环保的首要参看标准。还有就是涂胶量对胶合强度的效果较大,但并不是说涂胶越多越好,涂胶量不要过少,也不要过多。提高热压温度和延伸涂胶单板陈化时间可以行进胶合板的强度。
Another important policy is that the amount of formaldehyde released must be qualified. Most of the formaldehyde emission of birch plywood comes from the adhesive products used, so whether the adhesive formaldehyde emission is qualified is a comment
Whether birch plywood is environmentally friendly depends on the standard. In addition, the amount of glue has a greater effect on the bonding strength, but it does not mean that the more glue the better, the amount of glue should not be too small or too much. Increasing the hot pressing temperature and extending the aging time of the glued veneer can advance the strength of the plywood.
