Le plastikhi yobunjineli inokwenziwa ngoomatshini kuyo nantoni na, ukusuka kwiigiya ezincinci (eziphantsi) kunye neebheringi ukuya kwi-sprockets ezinkulu-iimilo ezinokuthi kude kube mva nje zinokwenzeka ngeentsimbi.Ayigqithisi kuphela isinyithi kwizicelo ze-abrasion, kulula ukuyifaka kumatshini kwaye ngenxa yoko inexabiso eliphantsi.Le plastikhi iguquguqukayo inokusilwa, icwangciswe, isarhiwe, yombiwe, kwaye ijikwe ukuze yenze iinxalenye ezininzi ngexabiso elikhuphisanayo.Inoxhathiso olubalaseleyo lwe-abrasion, ukumelana nempembelelo ephezulu, ukungancamatheli kunye nokuzithambisa kunye neempawu ezigqwesileyo zoomatshini, nakwimeko ye-cryogenic.
Izinto ezilungileyo ze-UHMWPE Rod
I-UHMWPE ayinavumba, ayinancasa, kwaye ayinatyhefu, Inokufunxeka okuphantsi kakhulu kokufuma okuphantsi kakhulu komlinganiso wokukhuhlana Ukuzithambisa ngokwawo kwaye imelana kakhulu nokurhawuka.Ukumelana kakhulu namanzi, ukufuma, uninzi lweekhemikhali Ezichasayo kwimitha ye-UV, kunye ne-micro-organisms.I-UHMWPE iba brittle kuphela kumaqondo obushushu angaphantsi −150 °C.
Isebenza njani intonga ye-UHMWPE?
UHMWPE intongainobuxhakaxhaka obumangalisayo kwi-abrasion kwaye inokugqithisa phantse nayiphi na iplastiki yobunjineli kulo mba.Inomdibaniso ophantsi kakhulu wokukhuhlane kwaye ibonelela ngesixhobo sokuthwala esisebenza simahla kwaye sihlala ixesha elide kakhulu.Iyakwazi ukumelana nee-acids ezininzi ezixubileyo, i-solvents kunye nee-agent zokucoca.Inobushushu bokusebenza obuphezulu bokudibanisa ne-90°C kunye nobushushu bokusebenza bexeshana elifutshane lokudibanisa ne-120°C.Isixhobo esinzima kakhulu, esinamandla amakhulu empembelelo yayo nayiphi na i-thermoplastic eyenziwe ngoku.
Isetyenziselwa ntoni i-UHMWPE Rod?Ngenxa yokuba intonga ye-UHMWPE inoxhathiso olugqwesileyo lwe-abrasion isoloko isetyenziselwa isanti, igrabile okanye iinkqubo ezidityanisiweyo.Ezi mekobume zinoburhalarhume ngokumangalisayo kuzo naziphi na izinto ezithwalayo kodwa i-UHMWPE yenye yeeplastiki ezimbalwa zobunjineli ezikwaziyo ukumelana nolo xhatshazo lokohlwaya.
I-UHMWPE Rod ingasetyenziselwa iipuli zokukhuhlana okuphantsi ngenxa yentsebenziswano ephantsi kakhulu ibonelela ngesixhobo sokuthwala esisebenza simahla kwaye sihlala ixesha elide.Ihlala ifumaneka kwiindawo zemveliso yokutya apho umthamo omkhulu wezikhongozeli kufuneka ukhokelwe ecaleni kokuhambisa okanye imigca yemveliso.Kuba inokufunxeka okuphantsi kakhulu kokufuma, ikwafumaneka kwezinye iindawo ezinemfuno ephezulu yezicelo zaselwandle.Ngamanye amaxesha isetyenziswa kumacandelo athile e-cryogenic ngenxa yobuchule bayo obuphantsi bobushushu bokusebenza.
Ngenxa yokuchasa ukunxiba kunye nefuthe, i-UHMWPE iyaqhubeka nokufumana usetyenziso lwemizi-mveliso olwandayo, kubandakanywa amacandelo eemoto kunye neebhotile.Ukusukela ngeminyaka yee-1960s, ikwayeyona nto isetyenziswa kakhulu kwi-joint arthroplasty kwi-orthopedic kunye nokufakelwa komqolo.
Zeziphi iimpawu machining of UHMWPE Rod?Isixhobo sentsimbi esinesantya esiphezulu siyacetyiswa ngeharika engasemva, iraki esecaleni kunye nococeko, kunye nerediyasi yempumlo enesisa.Sebenzisa isilumkiso xa ujika i-UHMWPE njengoko iitshiphusi ziya kuqhubeka kwaye zithande ukusonga isixhobo ukuze kucetyiswe “isenzo sokugqogqa”.
I-Gluing kunye ne-bondingUHMWPE ayifunxi amanzi ngokukhawuleza, okanye imanzi ngokulula, nto leyo eyenza ukuba idibanise kwezinye iipholima ezinzima.
Ngaba i-UHMWPE Rod ilungile kwizicelo zokutya?Ibakala lendalo le-UHMWPE yi-FDA evunyiweyo ukuba isetyenziswe kwizicelo zokutya.
Ngaba i-UHMWPE Rod inoxhathiso oluhle lwe-Wear?Intonga ye-UHMWPE ixhathisa kakhulu kwi-abrasion, kwezinye iifom ibe ngamaxesha angama-15 ukuxhathisa ukukrazula kunentsimbi ye-carbon.
Ukumelana neekhemikhaliInokumelana kakhulu neekhemikhali ezonakalisayo ngaphandle kwe-oxidizing acids
Iimpawu ezizodwaI-coefficient ye-friction isezantsi kakhulu kune-nylon kunye ne-acetal, kwaye ithelekiseka naleyo ye-PTFE, okanye i-polymer.Ulusu alusebenzisani nalo ngamandla, lusenza ukuba umphezulu ube mtyibilizi, uphantse ube ne-waxy.
Kutheni kufuneka ukhethe i-UHMWPE Rod?Le plastiki yobunjineli inomlinganiso ophantsi kakhulu wokukhuhlana obonelela ngeempawu zokutyibilika ezigqwesileyo kwaye sesinye sezona zixhobo zibalaseleyo zokunxiba kunye nokuxhathisa i-abrasion.Iqinile nakumaqondo obushushu aphantsi, inika ubunzima obuphantsi, kwaye kulula ukuyidibanisa.
