水泥的应用已日趋广泛,然而水泥的包装却大成问题,令人头痛。据不安全统计,我国每年生产水泥袋包装纸,就要耗费300万立米木材,26万吨烧碱。而且破损率特大,由此而损失的水泥竟高达50万吨以上,实在令人吃惊,致使水泥成本大大增加。为此,我国科学家经过多年的研究探索,终于在去年研究成功了一种新型的优质水泥包装材料——编织水泥袋,有效地解决了这一难题。这种编织水泥袋是以聚丙烯为原料,加工成扁丝,然后编织成袋。它由三层组成,外层是聚丙烯扁丝编织布,主要是对水泥内袋起保护作用,中层是聚丙烯薄膜,主要起隔水防潮作用,里层则是柔韧性较强
The application of cement has become more and more widespread, however, the packaging of cement has become a big problem and a headache. According to unsafe statistics, China annually produces 3 million cubic meters of lumber and 260,000 tons of caustic soda every year. And the damage rate is extremely large, resulting in the loss of cement as high as 500,000 tons or more, it is really surprising, resulting in a substantial increase in the cost of cement. To this end, our scientists after years of research and exploration, finally succeeded in last year’s study of a new type of high-quality cement packaging materials - woven cement bags, effectively solve this problem. This kind of woven cement bag is made of polypropylene as raw material, processed into flat yarn, and then woven into a bag. It is composed of three layers, the outer layer is polypropylene flat silk cloth, mainly to play a protective role in the cement bag, the middle layer is a polypropylene film, the main moisture from the moisture barrier, the inner is more flexible
