Description

一种胶黏物去除酶
技术领域
本发明涉及胶黏物去除酶领域，特别是涉及一种胶黏物去除酶。
背景技术
在制浆造纸过程中，纸浆中的树脂会以多种方式沉积在设备的表面上，从而产生一系列树脂障碍。一个日产1000t的针叶木硫酸盐漂白浆厂，每年由于树脂问题而引起的损失高达上千万美元。纸浆中树脂的沉积会导致产品质量、产量的下降。
二次纤维的重复回用使造纸系统中的杂质如：油墨载体、胶乳类、热熔树脂以及箱板纸中的错质等有害胶粘物会越来越多的累积于废纸浆和纸机的白水系统中，当积聚到一定程度时会沉积并粘附在成形网、干网、毛毯、压辊、烘缸表面及管道中形成污染物，造成糊网、堵网孔、粘烘缸及使湿部脱水不均匀。
发明内容
本发明的目的是提供一种使用成本低、酸雾抑制效果好的胶黏物去除酶。
本发明通过如下技术方案实现上述目的：一种胶黏物去除酶，其组分按质量百分比计，包括：纤维素酶25％、淀粉酶5％、果胶酶20％、木聚糖酶25％、丙二醇15％、水10％。
