近年来,纸张供需矛盾突出。为适应这种情况,一方面对现有造纸工厂进行扩建或改建;另一方面乡镇小型造纸作坊有很大发展。因此,造纸用的原、材、辅料出现供不应求。伴随生产的发展,环境污染、职业中毒和职业病的危害这一新课题又摆在了我们的面前。 In recent years, the contradiction between supply and demand of paper is outstanding. In order to adapt to this situation, on the one hand, the existing paper-making factories were expanded or rebuilt; on the other hand, small and medium-sized paper-making workshops in towns and townships have greatly developed. Therefore, the original paper, paper, accessories appear in short supply. With the development of production, environmental pollution, occupational poisoning and occupational hazards of this new issue is placed in front of us.
