Ichi chinyorwa chinoongorora kugona kwemurazvo kurapwa kwePTFE pamusoro pekugadzirisa uye inoenzanisa mhedzisiro ne corona uye plasma kurapwa. Zvinogoneka: murazvo unogona kushandura PTFE asi isingawanzo shandiswa mumaindasitiri - njodzi dzekuchengetedza (PTFE inoora ichiburitsa chepfu HF uye perfluoroisobutylene); kushanda zvishoma (simba repamusoro chete 30-35 mN / m, inoumba muganhu usina simba). Maitiro ekushanda: murazvo - kwenguva pfupi yakakwirira-tembiricha oxidation (> 1000 ° C), zvishoma etching, mashoma mapoka eokisijeni; corona - high-voltage discharge inogadzira ozone / inoshanda okisijeni, yakapfava oxidation, yakaderera simba density haigone kutyora CF zvisungo; plasma - yakakwirira-simba zvimedu / maerekitironi / emahara radicals anotsemura zvakananga maCF bond uye kubatanidza polar mapoka (hydroxyl, carboxyl, amino).
