前几年,英山县生资公司每年都要购买几千条聚氯乙烯塑料化肥袋,更换尿素的破包装,使费用增加很大。去年六月,他们用电熨斗补聚乙烯破尿素包装袋,解决了尿素破袋问题,降低了费用,效果很好。电熨斗补聚乙烯尿素袋方法简便易行。将尿素袋破处擦净铺平,取一块同质的塑料布,再垫上一块石棉布,将熨斗升温到300℃ In the past few years, the Yingshan County Health Care Company had to purchase thousands of PVC plastic chemical fertilizer bags every year, replacing the broken packaging of urea, which increased the cost greatly. In June last year, they used an electric iron to fill the polyethylene broken urea bags, solved the problem of urea broken bags, reduced costs, and worked well. The method of filling the polyethylene urea bag with the electric iron is simple and easy. Wipe and flatten the broken urea bag, take a piece of homogenous plastic cloth, put a piece of asbestos cloth, and raise the iron to 300°C.
