Farqiga u dhexeeya PVDF iyo daahan budada ah

Dad badan ayaan ka aqoon PVDF iyo daahan budada ah.Maanta waxaan si faahfaahsan u sharxi doonaa farqiga u dhexeeya PVDF iyo daahan budada ah.

1. Rinjiga la isticmaalo

PVDF, rinjiga loo isticmaalo waa rinjiga fluorocarbon PVDF iyo PVDF primer gaar ah, labaduba waa rinji dareere ah oo dareere ah.

5. Rinjiga dhumucda filimka

PVDF: 35-60um.

Daahan budada: 60-120um, iyadoo ku xiran nooca farqiga.

6. Muuqashada

PVDF: cad, macdan.Dhallaanka guud ahaan ma sarreeyo.
