乳膠漆甲醛含量超標可能原因及對策

發布日期:2022-04-26 點擊率:120

乳膠漆甲醛含量超標可能由以下原因產生:

1、防腐防霉劑含甲醛或釋放甲醛。解決方法是將防腐防霉劑的甲醛含量降下來,或采用不含甲醛或布釋放甲醛的防腐防霉劑。當然,這樣做是要承擔提高成本或失去容器上部空間保護的危險。

2、乳液中帶入甲醛。解決辦法是要求供應商降低乳液中甲醛含量,或另選甲醛含量較低的乳液。正在報批的《建筑涂料用乳液》國家標準對內墻涂料用乳液甲醛限量為0.08g/kg。

3、其組分帶入甲醛。比如色漿這類,找出原因,加以解決。



另外,甲醛的檢測作為建筑涂料所必須的檢測項目之一,通過甲醛測試儀可以快速的對樣品進行檢測。南北潮商城所提供的甲醛測試儀器可供參考。
