一种非淋膜防水纸的生产工艺

Production Technology of a Non-Leached Waterproof Paper

传统防水纸是在纸表面覆塑一层防水介质膜,进而形成一种淋膜防水纸使其具有防水性。但这种纸制品却在使用时不能全部降解,所以易造成环境污染,同时这种纸会给以后废纸回收处理以及造纸中纤维二次回收再利用带来一定困难。本文主要阐述了一种通过浆内施胶及表面施胶的方法研发的非淋膜防水纸的生产工艺,从透气度、接触角、纵向抗张强度等方面分析,对非淋膜防水纸的生产工艺进行探讨。

The traditional waterproof paper are coated with a layer of dielectric film on the surface of the paper,which makes it waterproof.However,this makes the paper products not completely degraded,causing environmental pollution,and brings difficulties to the future recycling of waste paper and the use of secondary fibers.This paper mainly expounds the production technology of a kind of non-drenched waterproof paper developed by the method of internal sizing and surface sizing,and discusses the production technology of non-drenched waterproof paper from the aspects of air permeability,contact angle,longitudinal tensile strength,etc.
