为防止粉尘污染,节约包装袋用纸浆,国家近年来一直致力于发展散装水泥,抑制袋装水泥。全国各地不少水泥生产企业积极进行技术改造,使水泥散装率大幅度提高。截至目前,全国散装水泥供应量达到1.11203亿t,散装率达到19.04%。袋装水泥在生产和使用过程中造成的粉尘,严重污染了大气 In order to prevent dust pollution and save paper pulp for packaging bags, the country has been devoting itself to developing bulk cement in recent years and suppressing bagged cement. Many cement manufacturing companies throughout the country have actively carried out technological transformations to increase the cement bulk rate. Up to now, the country’s bulk cement supply has reached 1.1120 billion tons and the bulk rate has reached 19.04%. The dust generated during the production and use of bagged cement seriously pollutes the atmosphere
