柔性杂质广泛存在于有机高分子溶液中,对过滤的影响显著而独特,受力可产生几乎任意大的变形,导致滤除困难、系统堵塞等问题,因此柔性杂质的表征、过滤质量的检测均存在特殊困难。本文介绍了一种以压差自动测量为基础的滤液质量检测方法,既适用于固体杂质,也能够反映柔性杂质含量。同时还引入过滤功率的概念,用来间接表征物料中柔性杂质的含量。结果表明,若过滤功率异常升高且固体粒度未发生显著变化,表示物料中柔性杂质含量异常增高。
柔性雜質廣汎存在于有機高分子溶液中,對過濾的影響顯著而獨特,受力可產生幾乎任意大的變形,導緻濾除睏難、繫統堵塞等問題,因此柔性雜質的錶徵、過濾質量的檢測均存在特殊睏難。本文介紹瞭一種以壓差自動測量為基礎的濾液質量檢測方法,既適用于固體雜質,也能夠反映柔性雜質含量。同時還引入過濾功率的概唸,用來間接錶徵物料中柔性雜質的含量。結果錶明,若過濾功率異常升高且固體粒度未髮生顯著變化,錶示物料中柔性雜質含量異常增高。

Soft impurities are widely present in organic solutions,and could have significant effects on filtration process.Soft impurities can be deformed to any angel under differential pressure,resulting in penetrating,plugging and other problems in the filtration system.An onsite testing method based on automatic differential pressure monitoring was described in this paper.This method is suitable for both solid and soft particles.Filtration power,a newly developed factor was introduced to indirectly express the content of soft impurities.It is regarded that soft impurities are higher when filtration power is higher while solid particle levels remains normal.
