当某些微粒的载体是油性的,并且这些物质附着在静电无纺布上时,电性能会降低,并且细小的灰尘会渗透。 因此,用于防止油气溶胶的过滤材料应进行特殊的静电处理,以防止细化。 防尘的目的。 因此,每个系列分为3个级别:95%,99%,99.97%(即称为95、99、100),因此有9小类过滤材料。

When the carrier of some particulates is oily, and these substances are attached to the electrostatic nonwoven fabric, the electrical properties will be reduced, and the fine dust will penetrate. Therefore, the filter material for preventing the oil and gas sol should undergo special electrostatic treatment to prevent the fineness. The purpose of dust. Therefore, each series is divided into 3 levels: 95%, 99%, 99.97% (that is, referred to as 95, 99, 100), so there are 9 small categories of filter materials.
