Izinto ezishelelayo zezindawo ezishelelayo zama-copier.
Izinto ezishelelayo zezindawo ezishelelayo zemishini yefayibha.
Izinto zokushelela zengxenye eshelelayo yemishini yokubopha izincwadi.
Izinto ezishelelayo zezindawo ezishelelayo zemishini yokunyathelisa.
Thatha iphedi yegundane njengesibonelo:
Uma kuqhathaniswa ne-Teflon (polytetrafluoroethylene PTFE), izinto ezisetshenziswa kuma-mouse pad endabuko, ifilimu ye-polyethylene UPE enesisindo sama-molecule esiphezulu kakhulu imelana nokuguguleka. Impahla yokuzigcoba ye-UPE iseduze neyezinto ze-Teflon. Ngesikhathi esifanayo, ngokombono wezindleko, ubuningi befilimu ye-polyethylene UPE enesisindo sama-molecule esiphezulu kakhulu buncane kakhulu, kanti i-polyethylene (UPE) enesisindo sama-molecule esiphezulu kakhulu (UPE) iphansi ngo-50% kune-Teflon ekuguqulweni kwesikwele. Ngakho-ke, ifilimu ye-polyethylene (UPE) enesisindo sama-molecule esiphezulu kakhulu iye yathatha indawo ye-ferroazol kancane kancane njengokukhetha kokuqala kwezinto zokusetshenziswa ze-foot pad zezindawo zokusekela.
Isicelo emkhakheni wetheyiphu:
Itheyiphu yokunamathela ezwela ukucindezela esekelwe kwifilimu ye-UHMWPE kanye ne-liner yokukhulula. Uma kuqhathaniswa namanye amatheyiphu okunamathela asebenzisa ifilimu ye-resin, ukumelana kwayo nomthelela kuphakeme, ukumelana nokuguguleka kanye nokuzigcoba kungcono.
Usayizi ojwayelekile
| Ubukhulu | Ububanzi | Umbala |
| 0.1～0.4mm | 10～300mm | omnyama, omhlophe noma owenziwe ngokwezifiso |
| 0.4～1mm | 10～100mm |
Isingeniso ku-UHMWPE:
I-polyethylene enesisindo sama-molecule esiphezulu kakhulu (UHMW-PE) ibhekisela ku-polyethylene eqondile enesisindo sama-molecule esimaphakathi esingaphezu kwezigidi ezingu-1.5. Ngenxa yesisindo sayo sama-molecule esiphezulu kakhulu (i-polyethylene evamile ingu-20,000 kuya ku-300,000, i-UHMW-PE inokusebenza okuphelele okungenakuqhathaniswa uma kuqhathaniswa ne-polyethylene evamile kanye nezinye ipulasitiki zobunjiniyela:
1) Ukumelana nokuguguleka okuphezulu kakhulu, okuphindwe kane kune-nylon 66 kanye ne-PTFE, okuphindwe kasithupha kune-carbon steel, okungcono kakhulu phakathi kwazo zonke izinhlayiya zokwenziwa okwamanje.
2) Amandla omthelela aphezulu kakhulu, okuphindwe kabili kune-polycarbonate kanye nokuphindwe kahlanu kune-ABS, futhi angagcina ukuqina okuphezulu ekushiseni kwe-nitrogen ewuketshezi (-196 ℃).
3) Impahla enhle yokuzigcoba, impahla yayo yokuzigcoba ilingana neye-PTFE, kanti i-coefficient yokungqubuzana ingu-0.07-0.11 kuphela; iyi-1/4-1/3 kuphela ye-coefficient yokungqubuzana kwensimbi.
4) Inani lokumuncwa kwamandla okushaqeka liphezulu kakhulu phakathi kwazo zonke ipulasitiki, futhi umphumela wokunciphisa umsindo muhle kakhulu.
5) Inamandla aphezulu okuqina kwamakhemikhali futhi ingamelana nezinhlobo ezahlukene zemidiya ebolile kanye nemidiya yemvelo ngaphakathi kwezinga lokushisa elithile kanye nobubanzi bokuhlushwa.
6) Amandla aqinile okulwa nokunamathela, alandela i-PTFE "yePlastic King".
7) Ihlanzekile ngokuphelele futhi ayinabo ubuthi, ingasetshenziswa lapho ithinta ukudla nemithi.
8) Ubuningi buncane kakhulu phakathi kwazo zonke ipulasitiki zobunjiniyela, bulula ngo-56% kune-PTFE kanye no-22% bulula kune-polycarbonate; ubuningi buyi-1/8 yensimbi, njalo njalo.
Ngenxa yokusebenza okuhle kakhulu okuphelele okungenhla, i-UHMW-PE ibizwa ngokuthi "ipulasitiki emangalisayo" ngamazwe aseYurophu naseMelika futhi iye yaziswa futhi yasetshenziswa kabanzi ezimbonini eziningi.
