摘要: 通过对PVA、聚丙烯酸类浆料及浆料助剂生物降解性能的论述表明,原淀粉和聚丙烯酰胺这两类浆料的生物降解性能较好,而PVA是最难进行生物降解的,其它浆料对生态环境均有一定的污染。浆料助剂多数为表面活性剂,疏水的碳链越长越难生物降解,直链结构较支链结构的生化降解性相对较好。为解决PVA难以降解的问题,目前已开发出新一代的生物分解酶,可使PVA废液快速生物降解。

Abstract: Having discussed biodegradability of PVA,polyacrylic acids size,and sizing agents,the paper summarizes: raw starch and polyacrylamide size exhibit better biodegradability,and PVA is most difficult for biodegradation.Other sizes will cause contamination to some extent to the ecology.Most of the sizing agents are surfactants,among them,in the case of the hydrophobic ones,longer the carbon chain,more difficult to biodegrade,and the straight chain structure has better biodegradability than the branch one.For solving the problem of hard degradation of PVA,a new generation of biodegradation enzymes has been developed,which can fast biodegrade PVA waste liquor.
