Lo pulasitiki wobunjiniyela ungenziwa ngomshini ube cishe noma yini, kusukela kumagiya amancane (umthwalo ophansi) nama-bearings kuye kuma-sprockets amakhulu—amamo okuze kube muva nje abengenzeka ngezinsimbi.Akugcini nje ngokudlula insimbi ezinhlelweni zokuhuzuka, kulula futhi ukuyifaka ngomshini ngakho ishibhile.Le pulasitiki enemisebenzi eminingi ingagaywa, ihlelwe, isanwe, ibhojwe futhi iguqulwe ukuze kwakhiwe izingxenye ezinkulu ezihlukahlukene ngentengo encintisana kakhulu.Inokumelana okuvelele kokuhuzuka, ukumelana nomthelela ophakeme, ukunganamatheli kanye nokuzigcoba kanye nezakhiwo ezinhle kakhulu zemishini, ngisho nasezimeni ze-cryogenic.
Izinzuzo ze-UHMWPE Rod
I-UHMWPE ayinaphunga, ayinambitheki, futhi ayinabo ubuthi, Imunca umswakama ophansi kakhulu i-coefficient ephansi kakhulu yokungqubuzana Iyazithambisa futhi imelana kakhulu nokuhuzuka.Imelana kakhulu namanzi, umswakama, amakhemikhali amaningi Ingazweli emisebeni ye-UV, kanye nama-micro-organisms.I-UHMWPE iba brittle kuphela emazingeni okushisa angaphansi kuka-−150 °C.
Isebenza kanjani i-UHMWPE Rod?
UHMWPE indukuinokumelana okumangalisayo nokuhuzuka futhi ingadlula cishe noma iyiphi ipulasitiki yobunjiniyela kulokhu.Ine-co-efficient ye-friction ephansi kakhulu futhi inikeza i-bearing medium esebenza mahhala kakhulu futhi ehlala isikhathi eside ngokuhlukile.Imelana nama-asidi amaningi ancibilikayo, izinyibilikisi nama-ejenti okuhlanza.Inezinga lokushisa eliphezulu lokusebenza elihlanganisa no-90°C kanye nezinga lokushisa lokusebenza lesikhashana elihlanganisa no-120°C.Into eqinile kakhulu, enamandla amakhulu omthelela wanoma iyiphi i-thermoplastic eyenziwe manje.
Isetshenziselwani i-UHMWPE Rod?Ngenxa yokuthi i-UHMWPE induku inokumelana okuhle kakhulu nokuhuzuka ivamise ukusetshenziselwa izinhlelo zokusebenza zesihlabathi, amatshe amatshe noma ama-aggregate.Lezi zindawo zinokhahlo olumangalisayo kunoma yiziphi izinto ezithwalayo kodwa i-UHMWPE ingenye yepulasitiki yobunjiniyela abambalwa ekwazi ukumelana nokuhlukumeza okunjalo okujezisayo.
I-UHMWPE Rod ingabuye isetshenziselwe ama-pulleys aphansi ngenxa yokusebenza kahle kwayo okuphansi kakhulu inikeza isisetshenziswa esithwalayo esisebenza mahhala kakhulu futhi esihlala isikhathi eside ngokuhlukile.Kuvame ukutholakala ezindaweni zokukhiqiza ukudla lapho umthamo omkhulu weziqukathi udinga ukuqondiswa eduze kwama-conveyor noma imigqa yokukhiqiza.Ngenxa yokuthi imunca umswakama ophansi kakhulu, iyatholakala futhi kwezinye izindawo ezidingeka kakhulu ezisetshenziswa olwandle.Kwesinye isikhathi isetshenziswa kwezinye izingxenye ze-cryogenic ngenxa yamakhono ayo okushisa aphansi okusebenza.
Ngenxa yokumelana nokuguga nokuba nomthelela, i-UHMWPE iyaqhubeka nokuthola izinhlelo zokusebenza ezikhulayo zezimboni, okuhlanganisa imboni yezimoto kanye namabhodlela.Kusukela ngeminyaka yawo-1960s, bekubuye kube yinto esetshenziswa kakhulu ukuhlanganisa i-arthroplasty ephelele ekufakweni kwamathambo nomgogodla.
Yiziphi izici zemishini ye-UHMWPE Rod?Kutuswa ukusebenzisa insimbi enesivinini esikhulu ngeraki engemuva, ireki eseceleni kanye nokuvula indawo, kanye nekhala elivulekile.Qaphela lapho uvula i-UHMWPE njengoba ama-chips ezoqhubeka futhi ejwayele ukugoqa amathuluzi ukuze "isenzo sokuqoba" siyelulekwe.
I-Gluing ne-bondingUHMWPE ayimumbi amanzi kalula, futhi ayimanzisi kalula, okwenza ukuhlanganisa amanye ama-polymer kube nzima.
Ingabe i-UHMWPE Rod ilungele ukusetshenziswa kokudla?Ibanga lemvelo le-UHMWPE yi-FDA egunyazwe ukuthi isetshenziselwe izicelo zokudla.
Ingabe i-UHMWPE Rod inokumelana okuhle kwe-Wear?Induku ye-UHMWPE imelana kakhulu nokuhuzuka, kwezinye izinhlobo imelana ngokuphindwe ka-15 ukuhuzuka kunensimbi ye-carbon.
Ukumelana namakhemikhaliImelana kakhulu namakhemikhali abolayo ngaphandle kwama-oxidizing acid
Izici ezihlukileI-coefficient yayo yokungqubuzana iphansi kakhulu kunaleyo inayiloni ne-acetal, futhi iqathaniswa naleyo ye-PTFE, noma i-polymer.Isikhumba asihlangani naso ngokuqinile, okwenza indawo engaphezulu izwakale ishelela, cishe i-waxy.
Kungani kufanele ukhethe i-UHMWPE Rod?Le pulasitiki yobunjiniyela ine-coefficient ephansi kakhulu yokungqubuzana enikeza izakhiwo ezinhle kakhulu zokushelela futhi ingenye yezinto ezihamba phambili zokumelana nokuguga nokuhuzuka.Iqinile ngisho emazingeni okushisa aphansi, inikeza isisindo esiphansi, futhi kulula ukuyishisela.
