Description

Предметом из-обретени вл етс способ получени древесных пластиков из шпона, состо щий в то:м, что шпон предварительно подвергаетс химическо обработке, затем склеиваетс бакелитовыми и другими лаками с при1месью опилок или другого вида порошковых материалов, причем в верхние слои пластика ввод т материю или бумагу.The object of the acquisition is a method for producing wood plastics from veneer, consisting of: that the veneer is first subjected to chemical treatment, then glued together with bakelite and other varnishes with a mixture of sawdust or other type of powder materials, and the upper layers of plastic are injected or paper.

Применение дл изготовлени дразесины njiacTiiKOB по отдельности всех вышеперечисленных операций, известно. Новостью вл етс применение их в совокупности, что дает положительный эффект.The use of separately producing all the above mentioned operations for the production of njiacTiiKOB is known. The news is their application in the aggregate, which has a positive effect.

Способ Олучепи древесных п.тастикги из шпона заключаетс в следуюилом.The method of Olupep wood veneer veneer is made as follows.

Смазка смола:ми шпона люжет прс1изводитс на вальцах. Затем шпон просушиваетс до исп,ареии летучих веш.естБ и после этого подвергаетс прессованию, причем дл фасонных пластиков, с це,1ью улучшени качества, склеивание допускаетс в две операцин:-сначала на плоских плитах холодным способом, а затем на фасонных.Lubricant resin: the veneer sheet is produced on rollers. Then, the veneer is dried to ISP, a region of volatile weighed BEST and then subjected to pressing, and for shaped plastics, with a quality improvement, bonding is allowed in two operations: first, on cold plates, and then on shaped ones.
