一、木工膠粘劑有毒嗎
膠粘劑是裝修的污染源之一,不少膠粘劑都含有微量甲醛和苯等有毒物質,木工膠粘劑是木工行業常用的膠粘劑,板式家具、人造板材等經常用到,那么木工膠有毒嗎?
一般來說,木(mu)(mu)(mu)工(gong)(gong)膠(jiao)按原料來源不同,可(ke)分(fen)為天然木(mu)(mu)(mu)工(gong)(gong)膠(jiao)和合成木(mu)(mu)(mu)工(gong)(gong)膠(jiao),天然木(mu)(mu)(mu)工(gong)(gong)膠(jiao)主(zhu)要是(shi)(shi)淀粉類和蛋白膠(jiao)類,一般是(shi)(shi)無毒(du)(du)的(de);合成木(mu)(mu)(mu)工(gong)(gong)膠(jiao)由(you)化學物質合成,是(shi)(shi)否有(you)(you)(you)毒(du)(du)要看它的(de)成分(fen),一般水性木(mu)(mu)(mu)工(gong)(gong)膠(jiao)是(shi)(shi)無毒(du)(du)環(huan)保的(de),溶(rong)劑型木(mu)(mu)(mu)工(gong)(gong)膠(jiao)含有(you)(you)(you)一定的(de)有(you)(you)(you)毒(du)(du)物質,不過正(zheng)規廠(chang)家生產的(de)木(mu)(mu)(mu)工(gong)(gong)膠(jiao),其(qi)有(you)(you)(you)害物質含量是(shi)(shi)在國家標準允許范圍內的(de)。
二、木工膠有甲醛嗎
很(hen)多(duo)朋友(you)都(dou)聽過(guo)“無醛(quan)不(bu)成(cheng)膠(jiao)”這句話,絕大部分膠(jiao)粘(zhan)劑都(dou)是含有甲醛(quan)的,木工(gong)(gong)膠(jiao)是木工(gong)(gong)行業使(shi)用的膠(jiao)粘(zhan)劑,那么木工(gong)(gong)膠(jiao)含甲醛(quan)嗎?
據(ju)了解,木工膠是否含(han)有(you)(you)甲(jia)醛(quan)(quan)(quan)要看其成(cheng)(cheng)分,有(you)(you)的(de)(de)木工膠是由特制的(de)(de)高(gao)分子乳液組成(cheng)(cheng)的(de)(de)單組份水基膠粘(zhan)劑,不含(han)甲(jia)醛(quan)(quan)(quan)、苯酚等(deng)有(you)(you)害物質;不過(guo)也有(you)(you)部分木工膠制作過(guo)程中會使(shi)用(yong)到脲醛(quan)(quan)(quan)樹脂膠,含(han)有(you)(you)一(yi)定量(liang)的(de)(de)甲(jia)醛(quan)(quan)(quan)。
三、木工膠對人體有害嗎
現如今使用的木工膠基本(ben)是(shi)化學物質合成的木工膠,使用不(bu)當可能會帶來危險,主要(yao)是(shi):
1、吸入:木(mu)工膠(jiao)的(de)蒸(zheng)氣可(ke)能會導致(zhi)頭痛、頭暈、嗜睡等問題。
2、接觸(chu):木工膠可能引起皮膚過敏和刺(ci)激,同時對眼睛等黏(nian)膜也有刺(ci)激作用。
3、吞食(shi):吞食(shi)木工膠可能對人體造成傷害,導致嚴重(zhong)的呼(hu)吸道問題。
