Thatha umzekelo wephedi yemawusi:
Xa kuthelekiswa neTeflon (polytetrafluoroethylene PTFE), izinto ezisetyenziswa kwiiphedi zemveli zegundane, ifilimu ye-polyethylene UPE enesisindo se-molecular esiphakamileyo kakhulu ayigugi. Ipropati yokuzithambisa ye-UPE isondele kakhulu kweyezinto zeTeflon. Kwangaxeshanye, ngokwembono yexabiso, uxinano lwefilimu ye-polyethylene UPE enesisindo se-molecular esiphakamileyo kakhulu luncinci, kwaye i-polyethylene (UPE) enesisindo se-molecular esiphakamileyo kakhulu iphantsi ngama-50% kuneTeflon ekuguqulweni kwesikwere. Ke ngoko, ifilimu ye-polyethylene (UPE) enesisindo se-molecular esiphakamileyo kakhulu iye yathatha indawo ye-ferroazol kancinci kancinci njengokhetho lokuqala lwezinto eziluhlaza zephedi yeenyawo kwiindawo zokusekwa.
Isicelo kwicandelo leteyipu:
Iteyiphu yokuncamathelisa ebuthathaka kuxinzelelo esekwe kwifilimu ye-UHMWPE kunye ne-liner yokukhulula. Xa kuthelekiswa nezinye iiteyiphu zokuncamathelisa ezisebenzisa ifilimu ye-resin, ukumelana kwayo nempembelelo kuphezulu, ukumelana nokukrweleka kunye nokuzithambisa ngokwakho kungcono.
Ubungakanani obuqhelekileyo
| Ubukhulu | Ububanzi | Umbala |
| 0.1～0.4mm | 10～300mm | mnyama, mhlophe okanye owenziwe ngokwezifiso |
| 0.4～1mm | 10～100mm |
Intshayelelo kwi-UHMWPE:
I-polyethylene enobunzima be-molecular obuphezulu kakhulu (UHMW-PE) ibhekisa kwi-polyethylene ethe tye enobunzima be-molecular obuphakathi kwe-1.5 yezigidi. Ngenxa yobunzima bayo be-molecular obuphezulu kakhulu (i-polyethylene eqhelekileyo ingama-20,000 ukuya kuma-300,000, i-UHMW-PE inomsebenzi opheleleyo ongenakuthelekiswa nanto xa ithelekiswa ne-polyethylene eqhelekileyo kunye nezinye iiplastiki zobunjineli:
1) Ukumelana nokuguguleka okuphezulu kakhulu, okuphindwe kane kune-nylon 66 kunye ne-PTFE, okuphindwe kathandathu kune-carbon steel, eyona ilungileyo phakathi kwazo zonke ii-resin zokwenziwa okwangoku.
2) Amandla empembelelo aphezulu kakhulu, aphindwe kabini kune-polycarbonate kwaye aphindwe kahlanu kune-ABS, kwaye anokugcina ukuqina okuphezulu kubushushu be-nitrogen engamanzi (-196 ℃).
3) Ipropati elungileyo yokuzithambisa, ipropati yayo yokuzithambisa ilingana neye-PTFE, kwaye i-coefficient yokungqubana yi-0.07-0.11 kuphela; yi-1/4-1/3 kuphela ye-coefficient yokungqubana yentsimbi.
4) Ixabiso lokufunxwa kwamandla okutsha lelona liphezulu kuzo zonke iiplastiki, kwaye isiphumo sokunciphisa ingxolo silungile kakhulu.
5) Izinzile kakhulu kwiikhemikhali kwaye inokumelana neentlobo ngeentlobo zemidiya ebolayo kunye nemidiya yendalo ngaphakathi kobushushu obuthile kunye noluhlu oluthile loxinzelelo.
6) Amandla okulwa nokunamathela aqinileyo, alandela i-PTFE "yePlastic King".
7) Icocekile ngokupheleleyo kwaye ayinabungozi, ingasetyenziswa xa idibene nokutya namayeza.
8) Uxinano lolona luncinci kuzo zonke iiplastiki zobunjineli, lukhaphukhaphu ngama-56% kune-PTFE kwaye lukhaphukhaphu ngama-22% kune-polycarbonate; uxinano luyi-1/8 yentsimbi, njalo njalo.
Ngenxa yokusebenza okugqwesileyo okuchazwe apha ngasentla, i-UHMW-PE ibizwa ngokuba yi-"amazing plastic" ngamazwe aseYurophu naseMelika kwaye iye yaxatyiswa kwaye yasetyenziswa kakhulu kumashishini amaninzi.
