Liquid filter bag

Liquid filter bag Introduction: The filtrate surface of the liquid filter bag is treated with special singeing, which not only effectively prevents the fibers from detaching from the contaminated filtrate, but also avoids the traditional roller pressing treatment that causes excessive clogging of the filter holes and shortens the life of the filter bag. All […]

Water and oil repellent filter material

Water and oil repellent filter material Water and oil repellent mechanism: Water and oil repellency means that the filter material is not wetted by water or oil to a certain extent. In theory, whether liquid B can wet solid A is determined by the surface tension of the liquid and the critical surface tension of the solid. If […]

Wet spinning

Wet spinning Introduction: Wet spinning is referred to as wet spinning. A chemical fiber spinning method in which polymer is dissolved in a solvent, and a thin stream is ejected through a spinneret, and then enters a coagulation bath to form fibers. The fiber-forming polymer suitable for wet spinning has a decomposition temperature lower than […]
