Kab lus no tshuaj xyuas qhov ua tau ntawm kev kho cov nplaim taws rau PTFE qhov chaw hloov kho thiab sib piv cov teebmeem nrog corona thiab kev kho ntshav ntshav. Kev ua tau zoo: nplaim hluav taws tuaj yeem hloov kho PTFE tab sis tsis tshua siv hauv kev lag luam - kev pheej hmoo kev nyab xeeb (PTFE decomposes tso tshuaj lom HF thiab perfluoroisobutylene); kev ua tau zoo txwv (nto lub zog tsuas yog 30-35 mN / m, cov ntaub ntawv tsis muaj zog ciam teb). Cov txheej txheem ua haujlwm: nplaim taws - qhov kub thiab txias oxidation (> 1000 ° C), me ntsis etching, ob peb pab pawg oxygen; corona - high-voltage paug generates ozone / nquag oxygen, oxidation me me, tsis tshua muaj zog ceev tsis tuaj yeem tawg CF daim ntawv cog lus; plasma - cov khoom siv hluav taws xob siab / hluav taws xob / cov dawb radicals ncaj qha cleave CF bonds thiab graft polar pawg (hydroxyl, carboxyl, amino).
