Cov yas engineering no tuaj yeem ua rau txhua yam zoo, los ntawm cov khoom me me (tsis tshua muaj load) cov kabmob thiab cov kabmob mus rau cov sprockets loj-puab uas kom txog rau thaum tsis ntev los no tsuas yog ua tau nrog hlau.Nws tsis tsuas yog outperforms hlau nyob rau hauv daim ntawv thov abrasion, nws kuj yog yooj yim dua rau tshuab thiab yog li pheej yig dua.Cov yas ntau yam no tuaj yeem milled, npaj, sawed, drilled, thiab tig los tsim ntau yam khoom ntawm tus nqi sib tw heev.Nws muaj qhov ua tau zoo tshaj plaws, kev cuam tshuam zoo tshaj, tsis yog-sticking thiab nws tus kheej-lubricating thiab cov khoom siv zoo heev, txawm tias nyob rau hauv cov xwm txheej cryogenic.
Qhov zoo ntawm UHMWPE Qws
UHMWPE tsis muaj ntxhiab tsw, tsis muaj ntxhiab, thiab tsis muaj tshuaj lom, Muaj qhov nqus dej tsis tshua muaj siab heev coefficient ntawm kev sib txhuam Nws tus kheej-lubricating thiab yog heev resistant rau puas.Heev tiv taus dej, noo noo, feem ntau cov tshuaj Resistant rau UV hluav taws xob, thiab micro-kab kab mob.UHMWPE tsuas yog nkig ntawm qhov kub hauv qab -150 ° C.
UHMWPE Qws ua haujlwm li cas?
UHMWPE rodmuaj qhov tsis txaus ntseeg tsis kam tiv thaiv kev puas tsuaj thiab tuaj yeem ua tau zoo tshaj yuav luag txhua yam yas yas hauv qhov no.Nws muaj kev sib txhuam qis heev thiab muab cov kabmob nruab nrab uas muaj kev khiav haujlwm dawb heev thiab ua haujlwm ntev heev.Nws yog resistant rau ntau dilute acids, kuab tshuaj thiab tshuaj ntxuav.Nws muaj qhov ua haujlwm siab tshaj plaws ntawm ntxiv rau 90 ° C thiab lub sijhawm ua haujlwm luv luv ntawm ntxiv rau 120 ° C.Cov khoom siv tawv heev, nrog lub zog siab tshaj plaws ntawm cov thermoplastic tam sim no ua.
UHMWPE Qws siv rau dab tsi?Vim tias UHMWPE pas nrig muaj qhov ua haujlwm zoo heev nws feem ntau siv rau cov xuab zeb, pob zeb lossis cov txheej txheem sib sau ua ke.Cov cheeb tsam no hnyav heev rau txhua yam khoom siv tab sis UHMWPE yog ib qho ntawm ob peb lub tshuab yas uas muaj peev xwm tiv taus qhov kev tsim txom no.
UHMWPE Qws kuj tseem siv tau rau cov kev sib txhuam tsis tshua muaj zog vim tias nws cov co-npaum qis heev muab cov kabmob nruab nrab uas khiav dawb heev thiab ntev ntev heev.Nws feem ntau pom muaj nyob rau hauv qhov chaw tsim khoom noj uas muaj cov ntim ntim ntau yuav tsum tau coj raws li cov khoom siv lossis cov kab ntau lawm.Vim tias nws muaj qhov nqus dej tsawg heev, nws kuj pom muaj nyob rau hauv qee qhov kev thov siab ntawm kev siv dej hiav txwv.Nws yog qee zaum siv hauv qee cov khoom siv cryogenic vim nws lub peev xwm ua haujlwm qis.
Vim tias nws tsis kam hnav thiab cuam tshuam, UHMWPE txuas ntxiv mus nrhiav kev tsim cov ntawv thov kev lag luam, suav nrog cov khoom siv tsheb thiab cov raj mis.Txij li thaum xyoo 1960, nws kuj yog cov khoom siv feem ntau siv rau tag nrho kev sib koom tes arthroplasty hauv orthopedic thiab txha nraub qaum.
Dab tsi yog cov yam ntxwv machining ntawm UHMWPE Qws?Kev kub ceev steel cuab yeej raug pom zoo nrog ntau lub nraub qaum, sab rake thiab clearances, thiab lub qhov ntswg dav dav.Siv ceev faj thaum tig UHMWPE raws li cov chips yuav tas mus li thiab nyiam qhwv ib ncig ntawm cov cuab yeej yog li qhia "pecking action".
Gluing thiab bondingUHMWPE tsis nqus dej yooj yim, los yog ntub dej yooj yim, uas ua rau kev sib txuas rau lwm cov polymers nyuaj.
Puas yog UHMWPE Qws zoo rau kev siv zaub mov?Ntuj qib UHMWPE yog FDA pom zoo siv rau hauv daim ntawv thov zaub mov.
Puas yog UHMWPE Qws muaj qhov hnav tsis zoo?UHMWPE pas nrig yog resistant rau abrasion, nyob rau hauv ib co ntaub ntawv yog 15 npaug ntau resistant rau abrasion dua carbon steel.
Tshuaj tiv thaiv Nws yog heev resistant rau corrosive tshuaj tsuas yog oxidizing acids
Cov yam ntxwv tshwj xeeb Nws cov coefficient ntawm kev sib txhuam yog qis dua li ntawm nylon thiab acetal, thiab yog piv rau PTFE, lossis polymer.Cov tawv nqaij tsis cuam tshuam nrog nws cov tawv nqaij, ua rau lub ntsej muag zoo nkauj, yuav luag waxy.
Vim li cas koj thiaj yuav tsum xaiv UHMWPE Qws?Qhov no engineering yas muaj qhov tshwj xeeb tsis tshua muaj coefficient ntawm kev sib txhuam uas muaj cov khoom siv zawv zawg zoo tshaj plaws thiab yog ib qho ntawm cov ntaub ntawv zoo tshaj plaws rau kev hnav thiab kev puas tsuaj.Nws yog ib qho nyuaj txawm tias qhov kub thiab txias, nws muaj qhov hnyav, thiab yooj yim rau vuam.
