Description

一种废纸再生纸张的制备方法及制备装置 技术领域
本发明涉及一种废纸再生纸张的制备方法及制备装置。
背景技术
20世纪，我国经济、社会、文化等各方面飞速发展，人们对环境保护越来越关注，人们的环保意识也随之增加，各部门均要求经济要在不牺牲环境的前提下发展。因此，各种废弃物的二次利用逐渐引起了大家的注意。
众所周知，造纸工业是一个与国民经济发展和社会文明建设息息相关的重要产业，而我国造纸产业与国际先进水平的差距很大，其中原料结构不合理和供给不足、资源浪费与环境污染是主要因素，提高废纸回收与利用水平对我国造纸工业发展有着重要的意义。虽然我国在废纸利用方面已经取得了较高的水平，但是我国的废纸回收水平低，导致每年都需要从国外进口大量的废纸，对国外废纸市场依赖性很强。
废纸，又被称为“二次纤维”，我国每年对各种纸张的消耗量极大，如果对废纸弃之不用，会造成资源的极大浪费。废纸再生不仅减少了对木材的消耗量，同时，再生纸的生产过程消耗的能源有明显的降低，其成本、环保处理费也相对较低，因此，废纸再生吸引了越来越多的注意。
目前市场上的再生纸张设备体积大、结构复杂、价格贵，因此适合在办公室、家庭中普遍使用。并且，现有的再生纸张的生产工艺过程复杂，大多需要经过碎浆、洗浆、脱水、研磨、脱墨、除渣处理后，再进行一系列操作之后才能制造出新的纸张。由于前述的制作工艺中，需要对废纸进行碎浆、洗浆、脱 水、脱墨和除渣处理。因此，将一张废纸放进现有的纸张再生机中，不可能完全的、全部得到同样大小的再生纸张。
在公司里、家里，每天都有很多文件、笔记和草稿，这些纸用了一次就扔掉，不但浪费资源，还污染环境，这与现在社会呼吁的节能完全背道而驰。为此，如何制造出能被办公室和家庭普遍使用的，且能由一张废纸完全得到一张再生纸本发明创造的发明动机。
