中国新型建材公司于1984年从英国引进两套稻草板生产线,分别在辽宁省盛产水稻的营口、盘锦两市安装投产。成品稻草板的质量优劣,贴面是重要环节,能否保证贴面的强度和质量,关键取决于对粘合剂性能、质量的选择和有效的调制。随稻草板生产线装置引进的配套胶CBU粉剂,性能、质量都好,但如长期使用,需耗大量外汇。国内用于木材胶合的脲醛树脂,如照搬到稻草板贴面上,几乎块块都是废品。稻草板的贴面工艺条件,要求胶粘剂必须能在一定温度下短时间内迅速固化,以保证生产的连续性。在这种情况下,我们进行了稻草板贴面用
In 1984, China New Building Materials Company introduced two sets of straw board production lines from Britain, which were installed and put into operation in Yingkou and Panjin, which are rich in rice in Liaoning Province. The quality of the finished straw board is important, and the veneer is an important link. Whether the strength and quality of the veneer can be guaranteed depends critically on the choice of adhesive properties and quality and effective modulation. The plastic CBU powder introduced with straw board production line equipment is of good performance and quality, but if it is used for a long time, it needs a lot of foreign exchange. Domestic urea-formaldehyde resins used for wood gluing, such as copying onto the straw slate surface, are almost scrap. The veneer board veneer process conditions require that the adhesive must be able to quickly cure at a certain temperature for a short period of time to ensure the continuity of production. In this case, we carried out the straw board veneering
