Thaum nrhiav cov khoom siv txhim khu kev qha thiab ruaj khov rau cov ntawv thov uas muaj kev hnav thiab cuam tshuam siab, tsis txhob nrhiav ntxiv lawm dua li daim ntawv UHMWPE. UHMWPE sawv cev rau Ultra High Molecular Weight Polyethylene thiab yog daim ntawv yas uas muaj kev ua tau zoo tshwj xeeb hauv cov xwm txheej hnyav. Nrog nws cov khoom sib xyaw ua ke, cov khoom siv no tau txais kev nyiam hauv ntau yam lag luam.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm daim ntawv UHMWPE yog nws qhov kev sib txhuam siab thiab kev cuam tshuam. Txawm hais tias nws yog kev hnav tsis tu ncua lossis kev sib txhuam los ntawm cov khoom hlau, cov khoom siv no tuaj yeem tiv taus nws. Los ntawm chute thiab hopper linings mus rau conveyors lossis cov khoom, hnav pads, tshuab rails, cuam tshuam nto thiab rails, UHMWPE daim ntawv yog thawj qhov kev xaiv.
Tab sis tsis yog li ntawd xwb! Daim ntawv UHMWPE muaj ntau lwm yam zoo uas ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv engineering. Ua ntej, nws tiv taus UV, uas txhais tau tias nws tuaj yeem tiv taus lub hnub ci ntev yam tsis muaj kev puas tsuaj. Qhov no ua rau nws tsim nyog rau kev siv sab nraum zoov, ua kom muaj lub neej ntev thiab kev ntseeg siab hauv txhua qhov xwm txheej huab cua.
Lwm qhov tseem ceeb ntawmDaim ntawv UHMWPEyog nws qhov kev siv tshuab zoo heev. Nws cov coefficient qis ntawm kev sib txhuam thiab yooj yim ntawm kev ua tiav ua rau nws yog cov khoom siv ntau yam rau kev siv tshuab. Txawm hais tias txiav, tho lossis tsim, UHMWPE daim ntawv tuaj yeem ua tiav tau yooj yim kom tau raws li cov kev xav tau tshwj xeeb, txuag lub sijhawm thiab kev siv zog.
Ntxiv mus, cov ntawv UHMWPE yuav luag tsis muaj zog tiv thaiv kev tawm tsam los ntawm tshuaj lom neeg. Nws tiv taus ntau yam tshuaj lom neeg, kua qaub thiab cov hauv paus, ua kom nws muaj kev ncaj ncees txawm tias nyob hauv qhov chaw nyuaj. Qhov no ua rau nws zoo tagnrho rau cov ntawv thov uas muaj kev raug rau cov tshuaj corrosive.
Ntxiv rau qhov tiv taus tshuaj lom neeg,Daim ntawv UHMWPEs kuj tsis thaiv thiab tsis lo. Qhov no txhais tau tias cov khoom siv thiab cov khib nyiab tsis tshua lo lossis lo rau ntawm nws qhov chaw, ua rau kev ua haujlwm du thiab txo qhov yuav tsum tau saib xyuas. Txawm hais tias nws yog cov nplej, thee lossis lwm yam khoom siv, UHMWPE daim ntawv ua kom muaj kev ntws zoo tshaj plaws thiab tiv thaiv kev txhaws.
Ntxiv rau, daim ntawv UHMWPE kuj muaj cov khoom siv hluav taws xob zoo heev. Nws muaj lub zog dielectric siab, ua rau nws yog ib qho insulator zoo tagnrho hauv kev siv hluav taws xob thiab hluav taws xob. Nws cov dej noo tsawg thiab cov khoom siv hluav taws xob zoo ua rau nws yog qhov kev xaiv txhim khu kev qha rau ntau yam chaw nyuaj.
Lwm qhov zoo ntawm daim ntawv UHMWPE yog nws lub peev xwm ua tau zoo hauv qhov kub txias. Tsis zoo li qee cov ntaub ntawv uas ua rau brittle hauv qhov txias heev, daim ntawv UHMWPE khaws nws cov tawv thiab yooj ywm txawm tias nyob rau hauv sub-zero kub. Qhov no ua rau nws haum rau cov ntawv thov uas xav tau kev ua tau zoo dua hauv qhov chaw txias.
Nyob rau hauv cov nqe lus ntawm kev tiv taus kub,Daim ntawv UHMWPEmuaj qhov kub siab tshaj plaws ntawm 80 ° F. Qhov no txhais tau tias nws tuaj yeem tiv taus qhov kub siab yam tsis muaj kev hloov pauv lossis pom tseebkev puas tsuaj. Txawm li cas los xij, cov kev cai tshwj xeeb ntawm daim ntawv thov thiab cov kev txwv kub yuav tsum tau txiav txim siab kom ntseeg tau tias muaj kev ua tau zoo tshaj plaws.
Thaum kawg, qhov nqus dej ntawm daim ntawv UHMWPE yog qis heev, tsawg dua 0.01%. Cov yam ntxwv no ua rau nws tiv taus dej noo, txawm tias nyob rau hauv qhov chaw noo noo, thiab txo qhov kev pheej hmoo ntawm kev o lossis kev hloov pauv loj. Qhov no ntxiv rau nws txoj kev ua tau zoo thiab kev ua haujlwm ntev.
Phaj yas UHMWPE siv rau qhov chaw uas muaj kev sib txhuam lossis qhov chaw uas cov khoom hlau sib ntsib, ua rau muaj kev sib txhuam lossis kev hnav. Nws zoo heev rau cov kab hauv lub chute thiab hopper, cov khoom xa khoom lossis cov khoom, cov ntaub qhwv hnav, cov lus qhia tshuab, qhov chaw cuam tshuam thiab cov lus qhia.
Xaus lus,Daim ntawv UHMWPEyog qhov kev daws teeb meem zoo tshaj plaws rau cov ntawv thov uas xav tau kev tiv thaiv kev sib txhuam thiab kev cuam tshuam siab. Nrog nws ntau yam khoom zoo xws li kev tiv thaiv UV, kev ua haujlwm tau zoo, kev tsis muaj tshuaj lom neeg, kev sib txhuam tsawg, tsis ua rau tawg, cov khoom siv hluav taws xob zoo, kev tiv thaiv txias, thiab kev nqus dej tsawg, nws tau dhau los ua cov khoom siv nyiam hauv ntau yam lag luam. Yog li, txawm tias koj tab tom nrhiav kev tiv thaiv kev hnav zoo dua lossis cov khoom siv txhim khu kev qha, daim ntawv UHMWPE yog koj cov lus teb!
