Polyamide (PA) sintered products

PA sintered filter element is made of high quality polymer polyethylene as the main raw material and carbon fiber through scientific formula sintering. Compact structure, strong, light weight, can withstand high filtration pressure, non-toxic and tasteless, has good corrosion resistance to acid and

1. PA microporous sintered filter element/filter rod

1. Strong acid and alkali corrosion resistance, resistance to the dissolution of organic solvents;

2. Excellent strength and wear resistance ensure its service life;

3. The surface of the external light makes the impurities not easy to stick;

4. Recoil and blowback are easy to reuse;

5. Good toughness, filter element is not easy to break;

6. No threshing phenomenon, strong pressure resistance.

4. PA microporous sintered filter element/filter rod regeneration method:

1, physical method: because the mechanical properties of the filter rod is good and will not break, it can use 0.6mpa compressed air for backblowing, backblowing at the same time plays a role of regeneration of pores, but after a long time of use in the accumulation of particles in the filter layer will affect the filtration speed, at this time, chemical regeneration must be carried out.

2, chemical method: the blocked PA filter rod is placed in the concentration of 5%-10% acid or lye immersion, so that the blockage in the filter layer of micro material neutralization, and then water backwash or air backwash clean, filter rod filtering effect can be restored
