摘要：
可冲散湿巾是一种使用后可直接丢入马桶冲散并分解的新型湿巾产品,由于其具有的方便性和环保性,将是未来湿巾产品的发展方向.对市场上4 种可冲散湿巾产品进行了物理分解、好氧生物分解和厌氧生物分解试验,研究了可冲散湿巾的物理分解和生物分解性能.结果表明,4 种可分散湿巾产品在经过3 h晃动试验后,外观形态呈现为散纤维状,物理分解百分比在 72%~78%间,产品均具有良好的物理分解性能;经过生物分解试验后,1#~4#样品厌氧生物可分解率分别为 100%、98.48%、100%和 100%,均大于 95%,4 种样品均通过了厌氧生物分解试验;1#~4#样品好氧生物可分解率则分别为 99.05%、100%、72.38%和 72.46%,其中 3#和4#样品未能通过好氧生物分解试验.目前市场上标识具有可冲散性的湿巾产品并非都能达到可冲散的目标.%The flushable wet wipes are a new type of wet wipes which can be disspread and decomposed directly in the toilet after use,because of its convenience and environmental protection,it will be the development direction of wet wipes in the future.The ex-periments of physical decomposition,aerobic biodecomposition and anaerobic biodecomposition of four kinds of flushable wet wipes from the market were carried out,the physical decomposition and biological decomposition properties of flushable wet wipes were studied.The results showed that after sloshing test for 3 h,the appearance of four kinds of flushable wet wipes appeared as fibrous form,the percentages of physical decomposition were 72%~78%,so all of them had good physical decomposition performance.Af-ter the experiments of biodecomposition,the anaerobic biodegradability of samples 1#~4#were 100%,98.48%,100% and 100% respectively,all samples passed the anaerobic biodecomposition test.The aerobic biodegradability of samples 1#~4#were 99.05%, 100%,72.38% and 72.46% respectively.The samples of 3#and 4#were failed to pass the aerobic biodecomposition test.The flush-able wet wipes in the market were not always able to achieve the goal of disperse.
