| Abstract: | Four kinds of liquids,Silwick,Galwick,polydimethylsiloxane and ultra-pure water were used to wetting samples,including spunlaced nonwovens,needle punched nonwovens,spunbond nonwovens,woven filter cloth,medium-speed filter paper,to study the effect of wetting liquid on the testing of pore size characteristics of fiber filter materials by bubble point method.The results show that the surface tension of the wetting liquid affects the testing results.Ultra-pure water cannot wet samples totally,the testing value of the samples wetted by ultra-pure water were higher than that of samples which be wetted by other liquids,so it is not suitable for being a wetting liquid.The other three kinds of liquids,Silwick,Galwick and polydimethylsiloxane wet the samples totally and the testing values be similar,so they are suitable for using as wetting liquids. |
