Abstract

现今使用的水泥袋,有的由3至4层纸袋纸制作而成,有的中间夹一层麻丝,前者耗费材料,后者因水泥会缓慢腐蚀麻丝,影响水泥袋的强度。本实用新型纸塑纸复合水泥袋里层和外层是纸袋纸,中间层是聚丙烯塑料编织丝,用这三层紧紧地粘合成一体的材料制作而成的纸塑纸复合水泥袋,既省材料,又比现今使用的水泥袋强度高,不易腐蚀和破损。

Description

纸塑纸复合水泥袋
本实用新型涉及一种包装水泥用的纸塑纸复合水泥袋。现今使用的水泥袋,有的由4层纸袋纸制作,耗费材料;有的由里外各一层纸袋纸中间夹一层麻丝制作,因水泥会缓慢腐蚀麻丝,进而影响水泥袋的强度。
本实用新型的目的在于提供一种既省材料,又能提高水泥袋的强度的新型水泥袋。
通过研究试产和试用,本实用新型纸塑纸复合水泥袋已制造出来,它的制作过程为:先将80至90根厚度为4至5丝、宽度为2.7至3.5mm、粘有特制胶水的聚丙烯塑料丝间隔整齐地排列贴近水泥袋里层纸袋纸的纵向方向上,经过辊筒压平实后,将上述相同的塑料丝16根绕织在里层纸袋纸的横向方向上,接着,将水泥袋的外层纸袋纸叠齐上去,并一同卷成纸塑纸复合水泥袋,再将它们送至辊筒进一步压平粘结,粘结后的纸塑纸复合水泥袋送往嵌针滚筒打孔,按每平方米面积均匀地打8500至9000个孔,每个孔的直径约为1毫米。纸塑纸复合水泥袋,总共有三层,里外两层通常使用规格为1020mm、80g/m2的纸袋纸,中间层间隔地排贴着聚丙烯塑料丝。图1是纸塑纸复合水泥袋的立体图,1是里层纸袋纸,2是按横向和纵向排粘在里层纸袋纸上的聚丙烯塑料丝,3是外层纸袋纸。
本实用新型纸塑纸复合水泥袋与现今使用的水泥袋相比,不易被水泥腐蚀,强度提高了,制做材料纸袋纸节省了,每个纸袋的成本降低了,现在很受用户欢迎。
