目前,废纸板的再生技术大部分是经过化浆造 纸,然后用纸板再加工成纸箱。过去对旧纸箱的翻新, 基本都采用以下两种方法:一是缝合、粘补,表面处 理,整体处理,重新印刷图案;二是将大纸箱拆散,重 新组合改制成小纸箱,再整形处理。这两种方法都存 在工序多、浪费大,改造后的纸箱平整度达不到要 求。为尽量节省,充分发挥废旧利用的优势,我们在现 有的基础上,将废旧纸板再利用技术进行了改进,该 技术的具体实施步聚如下: At present, most of the recycling technology of waste paperboard is through pulp and papermaking, and then re-processed into cardboard boxes with cardboard. In the past on the renovation of the old cartons, the basic use of the following two methods: First, suture, adhesive repair, surface treatment, the overall treatment, re-print the pattern; the second is to break up the large carton, reorganized and reorganized into small cartons, and then plastic treatment. These two methods exist in many processes, waste large, the transformation of the flatness of the carton did not meet the requirements. In order to save as much as possible and give full play to the advantages of waste utilization, on the basis of our existing technology, we improved the recycling technology of used paperboard. The concrete implementation steps of this technology are as follows:
