Product Description
Nylon microporous membrane is a natural hydrophilic membrane with very good chemical compatibility. It can filter all aqueous solutions and most organic solvents, such as alcohols, ethers, esters, ketones, etc. etc., with a wide range of chemical compatibility. MS nylon microporous membranes are widely used in sample collection, sample pre-filtration, sample detection and removal of particles, bacteria, microorganisms, etc.
● Type: Flat, Roll.
● Process: Hot press lamination, no glue. Or cast film.
● Grade: industrial, food, pharmaceutical grade.
● Properties: Naturally hydrophilic, Contact angle<45 degrees.
● Application: Liquid filtration.
Model and properties of membranes
1. Grid membrane:
Material: 100% PA6 or PA66.
Process: Fine silk thread machine weaving, heat setting.
Pore diameter: average ≥5.0um, MF grade,
Application: Retain or remove larger SS (suspended solids) in the liquid,
Structure: (Front and Back SEM)
2. Asymmetric membrane
Material: 100% PA6 or PA66.
Process: Cast film ，Unsupported type, clip skeleton type.
Aperture: Asymmetry. The aperture on one side is large and the other side is small,
◆ UF grade: 0.05，0.10（um）
◆ MF grade: 0.22, 0.45, 1.0, 3.0,5.0,10.0(um)
Structure:
| Surface low magnification SEM |
 |  |
One side (large aperture) SEM |
The other side (small aperture) SEM |

Different usage methods and features:
1. Liquid--macroporous membrane surface--contamination-holding laye--small pore membrane surface--permeate.
◆ Impurities are graded and intercepted, and the membrane is not easily blocked.
◆ Low initial working pressure, high initial flow,
◆ Impurities are removed along with the replacement of the membrane,
◆ Applicable to: high accuracy rate impurity removal + filtering method.
2. Liquid--small pore membrane surfac--macroporous membrane surface--permeate
◆ Impurities are effectively intercepted on the surface of the membrane and remain in the liquid,
◆ Impurities are concentrated on the surface of the membrane, and the inside is not easy to clog,
◆ It can be restored by backwashing or aeration cleaning, and has a long service life.
◆ Applicable to: suspension slurry, impurity removal + concentration.
