Unyango lomphezulu we-PTFE wokudibanisa ukunamathela usebenzisa iindlela ezimbini eziphambili: ukunyibilika kobushushu obuphezulu (ukumelana nemozulu ephezulu, amandla angama-9.5 MPa kunye ne-agent edibeneyo, kodwa ikhupha iigesi ezinetyhefu) kunye ne-sodium-naphthalene etching (i-5 MPa yokubambelela ngokukhawuleza, i-window yeyure ye-24-48 encinci, inkunkuma eyingozi). Khetha ngokusekelwe kulawulo lokusingqongileyo kunye nexesha elide vs. ukusebenza kwexesha elifutshane.

Ukuvavanya umgangatho we-emulsion we-PTFE ubandakanya izibonakaliso ezintandathu eziphambili: umxholo oqinileyo (60±2% nge-T / FSI 067-2021), i-pH (9.0-11.0), ukusabalalisa ubungakanani besuntswana (i-laser diffraction/DLS), i-viscosity (12-30 mPa·s kwi-25 ° C), ukuzinza (i-centrifugal kunye nokubonakala kwe-thaw, i-freeze-thaw). Esi sikhokelo sibandakanya iindlela zovavanyo eziqhelekileyo kwipharamitha nganye.
