甲醛在制胶生产中精制和再生处理

Refining and recycling treatment for formaldehyde in glue production

制胶生产中使用的甲醛溶液存在甲酸含量及铁含量过高等问题必须进行精制处理，并对甲醛贮存过程中形成聚甲醛进行解聚及再生利用，以便工业甲醛溶液更适合于制胶生产应用。处理方法简单、装置增设不多、对提高胶粘剂质量和降低成本作用明显，十分适宜于大型制胶厂家的应用。

Formaldehyde solution used in glue production is of over high contents of formate and iron,the question should be refined treatment,as well as depolymerizing the polymerizing formaldehyde forming in the course of storement and recycling utilization,so that industrial formaldehyde solution more fits for glue production application.Its simple treatment method, the equipment doesn't increase more,it is very effective for improving glue adhesive quality and reducing cost,more fitting for big glue factories to use.
