Description

一种甲醛去除剂 技术领域
本发明具体涉及一种甲醛去除剂。
背景技术
甲醛为较高毒性的物质，在中国有毒化学品优先控制名单上甲醛高居第二位。甲醛已经被世界卫生组织确定为致癌和致畸形物质，是公认的变态反应源，也是潜在的强致突变物之一。研究表明，甲醛具有强烈的致癌和促癌作用。甲醛对人体健康的影响主要表现在嗅觉异常、刺激、过敏、肺功能异常、肝功能异常和免疫功能异常等方面。
长期接触低剂量甲醛可引起慢性呼吸道疾病，还可引起鼻咽癌、结肠癌、脑瘤、月经紊乱和细胞核的基因突变，还可引起DNA单链内交连和DNA与蛋白质交连及抑制DNA损伤的修复、妊娠综合症、引起新生儿染色体异常、白血病等，还会引起青少年记忆力和智力下降。
通常装修后的房子甲醛都会超标。近年来，新装修教室甲醛超标，异味明显，已引起教育主管部门、媒体以及家长的广泛关注。同时，由于教室相对于家庭或其它办公场所，人员更加密集，且在教室使用期间，为保障良好的教学环境，基本都处于门窗户关闭状态，这又加重了甲醛或PM2.5等在教室空气中的累积，容易引发群体性的事件。
教室内甲醛等污染主要来源于课桌椅，墙面涂料以及窗帘或地板等地面铺装材料。其内环境中的PM2.5等则主要与室外大气污染程度有关，在秋冬或早春季节室外空气污染程度尤其严重。教室装修尽可能的选择高环保等级的人造板材、墙面涂料以及胶粘剂，但甲醛等污染不可避免。
