国产的水泥因水泥袋的质量问题,每年破损率为15～20%,直接损失300万吨水泥,相当于全国年产量的3%。产生的原因分析如下:1.出厂的水泥袋不坚固。2.水泥在运输装卸过程中人为因素的影响。3.自然因素如雨水水分的影响等。
Due to the quality problem of cement bags, the domestically produced cement has an annual breakage rate of 15 to 20% and direct loss of 3 million tons of cement, which is equivalent to 3% of the national annual output. The reasons for the analysis are as follows: 1. The factory cement bag is not strong. 2. The influence of human factors on the cement during transportation loading and unloading. 3. Natural factors such as the effects of rain and moisture.
