              书本到底会不会释放游离甲醛呢?

              浏览:39 来源:广州隆天环保公司招商?#29992;?#23448;网http://www.hodk.icu/ 时间:2018-12-15 分类:治理知识

                   书房家人是孩子经常做作业看书的地方,如果书房甲醛超标,家人孩子的身体健康就很难有保证。因此,书本会不会释放游离甲醛是很家长关心的话题。那么,书本到底会不会释放游离甲醛呢?


              书本是否会释放游离甲醛?


                      印刷书本中的着色材料油墨主体是酚醛树脂,这个酚醛树脂是怎么来的呢?就是甲醛跟一些酚去缩合而成?#27169;?#36824;有一些辅助增稠剂、稳定剂等?#21462;?#19981;过目前大多数印刷厂?#23478;?#32463;升级使用环保油墨,里面的油都是豆?#20572;?#21487;以减少像甲醛等有机溶剂的挥发。


                     书本纸张,都是由木材、?#29616;降任?#21407;材料打碎后制作成纸浆,再经过滤晾干后形成,但不否认木材里面含有少量的甲醛,不过甲醛的含量很少,对人体几乎不造成影响。另外,装订书本用的胶水大多数是EVA热熔胶,?#35805;?#19981;会造成甲醛释放量超标的。

                    通常新房甲醛超标通常是因为地板、书柜、木制家具等装饰材料本身含有甲醛,释放的甲醛叠加所导致的。书房检测出来甲醛超标,并不能直接?#24471;?#20070;本身排放超标,很可能只是书本里释放的少量甲醛释放让数值更高,让书房测出的甲醛释放量会偏高。因此,书房甲醛超标把原因全归为书本并不科学。
