Compared with traditional materials, the application of three-layer and five-layer high-efficiency filter paper has become more and more widespread. It can be applied to many fields and brings a lot of convenience to people’s production and life.
Let’s find out today.
The production of filter paper is very simple. It is nothing more than soaking a variety of fibers in a water-based binder to completely disperse them, and then forming a tightly connected connected paper roll on the silk screen, which is dried, impregnated, and then Dry to an acceptable humidity level.
But in fact, manufacturing efficient filter paper and maintaining consistent performance from batch to batch, roll to roll, and even year to year requires a very narrow range of changes in its weight, porosity, air permeability, strength, etc.
Three layers and five layers of high-efficiency filter paper are membranes with screening functions.
Polytetrafluoroethylene is a linear polymer. Due to its high polymer chain and low cohesive energy, there is no suitable solvent to prepare the casting liquid. It can only be sintered, cut, stretched or extruded to form a film. .
The intergranular region forms pores and becomes a microfiltration membrane.
If combined with polyethylene mesh, it can be made into a high-strength microfiltration membrane.
It has good chemical stability, is resistant to strong acids, strong alkali, strong oxidants and organic solvents, and can be used at high temperatures.
Suzhou New Material Technology Co., Ltd. is a fluorine material film manufacturer that integrates the research, development, production and sales of PTFE air filtration membranes, PTFE bubble point membranes, three-layer and five-layer high-efficiency filter papers, Teflon films and coated filter materials.
The company has advanced PTFE film production lines, lamination and composite production lines, which are at the domestic advanced level.
