PTFE pamwamba mankhwala kwa kugwirizana adhesion amagwiritsa ntchito njira zikuluzikulu ziwiri: mkulu-kutentha kusungunuka (apamwamba nyengo kukana, 9.5 MPa mphamvu ndi coupling wothandizila, koma amatulutsa poizoni mpweya) ndi sodium-naphthalene etching (5 MPa yomweyo adhesion, yopapatiza 24-48 maora zenera, zinyalala zoopsa). Sankhani potengera kuwongolera chilengedwe komanso nthawi yayitali vs.
