Description

环境湿度调节物品 技术领域
本发明具体涉及一种环境湿度调节物品。
背景技术
“湿度”是影响各行各业的产品包装及储存保质期的重要因素。每个产品都需要一个合理的湿度范围来储存。例如，中草药的保存湿度是55～68％左右，环境湿度低于该数值会使得中草药的损耗增加，而且降低中草药的品质；环境湿度高于该数值会引起中草药的腐败，导致中草药变质无法使用。干藏库中对某些食品的保持湿度为55～68％左右，环境湿度低于该数值会使得食品的品质降低；环境湿度高于该数值会引起食物的腐败，甚至引发食物中毒。
为了将环境湿度控制55％-68％，常用的方式是采用调湿硅胶对环境进行调湿，但是调湿硅胶的使用不符合绿色环保产品。在生产调湿硅胶过程中产生大量的废水，为了环保很多硅胶原料工厂都关闭整顿。这导致各个行业把原来物料清单表中最不重要的干燥剂产品也开始列入重要物资的采购清单。
因而，目前急需一种调湿硅胶的替代品，而且该替代品必须符合绿色环保的主旨。
