PTFE ine mukurumbira wayo yakaderera friction coefficient (0.05-0.10). Asi rinhi PTFE tepi yekushisa yepamusoro abrasion resistance .
Pasina kusarudzwa kwakakodzera, iyo PTFE yekupfekedza inopfeka mukati memavhiki, ichifumura iyo fiberglass substrate uye kukonzera kutadza kunotyisa. Tepi isiri-tsvimbo yakajairwa haina kugadzirwa kuti iite dynamic sliding contact.
Aokai PTFE yakagadzira matepi asingapfeki ePTFE ekuda kutsvedza maapplication. Iri gwara rinofukidza zvishanu zvakakosha kufunga: abrasion resistance metrics, coating quality, thermal stability, adhesive performance, uye nzira dzekuisa.

Nei Taber abrasion ichikosha: Yakachena PTFE coating inopfeka nekukurumidza pasi pekutsvedza kubata. Yakazadzwa yakagadziridzwa PTFE (ine kabhoni faibha, graphite, MoS₂, kana girazi fiber) inoderedza zvakanyanya mwero wekupfeka. Premium kupfeka-resistant tepi inogona kuwana <5 mg kurasikirwa pa1000 cycles - 20-50x zviri nani pane isina kuzadzwa PTFE.
PV muganho unotsanangurwa: Yakakura inotenderwa chigadzirwa chekubata Pressure (P) uye inotsvedza Velocity (V). Kupfuura muganho uyu kunokonzera kukurumidza kupfeka, kupisa, kana kukanda kukundikana. Gara uchikumbira PV curves kubva kumutengesi wako.
Aokai PTFE inopa kupfeka-resistant tepi mamakisi neTaber abrasion kurasikirwa pasi pe10 mg/1000 cycles - yakasimbiswa neyakazvimirira ASTM D4060 bvunzo. Yedu kabhoni-fiber-yakazadzwa kuumbwa inochengetedza μ pazasi 0.15 kunyangwe mushure megumi, 000 kutenderera.

Ongorora: Kune inorema-mutoro kutsvedza maapplication uko tepi iri pasi pekuenderera kwekuveura kushushikana, funga mechanical fasting (rivets, clamping mitsetse) mukuwedzera kune adhesive.
5. Surface Texture & Thickness Uniformity
Mamiriro epamusoro: Magadzirirwo akashongedzwa zvishoma anobatsira kuchengetedza marara, kudzivirira coefficient spikes kana gejo-abrasive kupfeka kunokonzerwa nezvidimbu zvakaunganidzwa.
Ukobvu kushivirira: Ukobvu hwakazara hunodzorwa mukati me ± 0.02 mm pakazara roll kuti ive nechokwadi chekumisikidza uye kudzivirira kuparara kwenzvimbo nguva isati yakwana.
