Thatha iphedi yegundane njengesibonelo:
Uma kuqhathaniswa ne-Teflon (i-polytetrafluoroethylene PTFE), izinto ezisetshenziswa kumagundane omdabu, ifilimu ye-ultra-high molecular weight polyethylene UPE imelana kakhulu.Indawo yokuzithambisa ye-UPE iseduze naleyo yezinto zeTeflon.Ngesikhathi esifanayo, ngokombono wezindleko, ukuminyana kwefilimu ye-polyethylene UPE yesisindo se-molecular ultra-high incane kakhulu, futhi i-ultra-high molecular weight polyethylene (UPE) ingaphansi ngo-50% kune-Teflon ekuguquleni kwesikwele.Ngakho-ke, ifilimu ye-ultra-high molecular weight polyethylene (UPE) kancane kancane ithathe indawo ye-ferroazol njengenketho yokuqala yezinto zokusetshenziswa zamaphedi onyawo ezisekelweni.
Isicelo emkhakheni we-tape:
Itheyiphu enamathelayo ezwela ukucindezela esekelwe kwifilimu ye-UHMWPE kanye nomugqa wokukhulula.Uma kuqhathaniswa namanye amateyipu anamathelayo asebenzisa ifilimu ye-resin, ukumelana kwawo komthelela kuphakeme, ukumelana ne-abrasion kanye nokuzigcoba kungcono.
Usayizi ojwayelekile
| Ubukhulu | Ububanzi | Umbala |
| 0.1-0.4mm | 10 - 300 mm | emnyama, emhlophe noma eyenziwe ngokwezifiso |
| 0.4-1mm | 10 ~ 100mm |
Isingeniso ku-UHMWPE:
I-polyethylene enesisindo se-Ultra-high molecular (UHMW-PE) ibhekisela ku-polyethylene ewumugqa enesisindo samangqamuzana esimaphakathi esingaphezu kwezigidi ezingu-1.5.Ngenxa yesisindo sayo samangqamuzana aphezulu kakhulu (i-polyethylene evamile ingu-20,000 kuya ku-300,000, i-UHMW-PE inokusebenza okuphelele okungenakuqhathaniswa uma kuqhathaniswa ne-polyethylene evamile namanye amapulasitiki wobunjiniyela:
I-1) Ukumelana nokugqoka okuphezulu kakhulu, izikhathi ezi-4 ziphakeme kunenayiloni 66 ne-PTFE, izikhathi ezi-6 ziphakeme kune-carbon steel, ehamba phambili phakathi kwazo zonke izinsalela zokwenziwa okwamanje.
2) Amandla omthelela aphakeme kakhulu, okuyizikhathi ezi-2 kunawe-polycarbonate futhi izikhathi ezi-5 kune-ABS, futhi angagcina ukuqina okuphezulu kuzinga lokushisa le-nitrogen eliwuketshezi (-196 ℃).
3) Impahla enhle yokuzigcoba ngokwayo, impahla yayo yokuzithambisa ilingana naleyo ye-PTFE, futhi i-coefficient ye-friction ingu-0.07-0.11 kuphela;iwu-1/4-1/3 kuphela we-coefficient yensimbi.
4) Inani lokumunca amandla okushaqeka liphezulu kakhulu kuwo wonke amapulasitiki, futhi umphumela wokunciphisa umsindo muhle kakhulu.
I-5) Inokuqina kwamakhemikhali aphezulu futhi ingamelana nemidiya ehlukahlukene ebolayo kanye nemidiya ye-organic ngaphakathi kwezinga lokushisa elithile kanye nebanga lokuhlushwa.
I-6) Ikhono eliqinile lokulwa nokunamathela, okwesibili kuphela ku-PTFE "Inkosi yePlastiki".
I-7) Ihlanzekile ngokuphelele futhi ingenabuthi, ingasetshenziswa ngokuthintana nokudla nemithi.
8) Ukuminyana kuncane kakhulu kuwo wonke amapulasitiki obunjiniyela, ama-56% alula kune-PTFE kanye no-22% alula kune-polycarbonate;ukuminyana kuyi-1/8 yensimbi, njalonjalo.
Ngenxa yokusebenza kahle okuhle kakhulu okungenhla, i-UHMW-PE ibizwa ngokuthi "ipulasitiki emangalisayo" ngamazwe ase-Europe naseMelika futhi iye yaziswa futhi yasetshenziswa kabanzi ezimbonini eziningi.
