由上海第二工业大学戚昌民、上海百货公司徐琦等六位同志研制的高分子树脂粘合剂于8月27日在上海通过鉴定。树脂粘合剂,其特点:①耐水性好(因它不含有NaOH不会吸收空气中的水份而受潮)。商品在储存和运转过程中,不致因吸潮而出现倒塌的问题;②粘结力强(基于分子中极性基因多,成膜性好,对纤维粘着力极大),可以在一定程度上减低纸箱用纸的克重;③中性无毒,生产及储运过程中接触人体无害,纸箱不泛碱;④原料成本低于现有的粘合剂(比淀粉粘合剂低30％左右);⑤生产工艺简于现在的粘合剂。经纸箱厂工人普遍反映该粘合剂备料方便容易使用,清洁,干净,提高了工作效益。对试制的纸箱使用厂反
Polymer resin adhesives developed by six comrades, Shanghai Second Polytechnic University, Qi Changmin and Xu Qi, Shanghai department store, passed the appraisal in Shanghai on August 27. Resin adhesive, its characteristics: ① water resistance is good (because it does not contain NaOH will not absorb moisture in the air and damp). Commodity storage and operation process, not because of moisture absorption and the collapse of the problem; ② strong binding (based on the molecular polar genes, the film is good, great adhesion to the fiber), to some extent Reduce the weight of the paper; ③ neutral non-toxic, harmless to the human body in the process of production and storage and transportation, the carton is not ubiquitous; ④ raw material cost is lower than the existing adhesive (30% About); ⑤ production process is simple in the current adhesives. The carton factory workers generally reflect the adhesive preparation easy to use, clean, clean, improve work efficiency. On the trial use of the carton factory counter
