UHMW-PE stands rau Ultra High Molecular Nyhav Polyethylene.Nws yog qhov zoo tshaj plaws polyethylene (PE) muaj, engineered rau cov hauj lwm nyuaj thiab ntau yam kev siv.
Nws muab kev txuag nyiaj hauv ntau daim ntawv thov nyuaj.Ultra High Molecular Nyhav yog qhov zais cia ntawm cov khoom siv polymer no.Nws cov high-density polyethylene resin muaj qhov hnyav molecular ntau ntawm 3 txog 6 lab, piv rau 300,000 txog 500,000 rau siab molecular hnyav (HMW) resins.Qhov sib txawv ntawd yog qhov ua kom cov khoom siv no muaj zog txaus los tiv thaiv kev puas tsuaj thiab cuam tshuam zoo dua li cov khoom lag luam poly qis.UHMW-PE lub siab molecular hnyav txhais tau tias nws yuav tsis yaj los yog ntws raws li cov kua molten.Cov txheej txheem ua tiav yog li muab los ntawm cov hmoov hlau tshuab.UHMW-PE tsis tuaj yeem hloov pauv thiab molded los ntawm cov txheej txheem ua cov yas (txhaj tshuaj molding, tshuab moulding lossis thermoforming).Compression molding yog cov txheej txheem hloov dua siab tshiab uas siv nrog cov khoom siv no vim tias nws tsim cov khoom muaj zog, zoo ib yam.
UHMW paub txog nws qhov kev ua haujlwm siab ua haujlwm, lub cev lubrication, lub zog muaj zog, tshuaj lom neeg-, corrosion-, thiab noo noo-ua haujlwm thiab acoustic impedance.
Vim nws qhov abrasion-, corrosion-, tshuaj- thiab ya raws-resistant zog, UHMW feem ntau yog siv nyob rau hauv cov ntaub ntawv uas tej zaum yuav hnyav heev rau lwm yam ntaub ntawv.Nws yog tus nqi-zoo siab ua haujlwm polymer siv los tsim cov nqi qis, cov khoom zoo.
UHMW yog cov khoom siv nws tus kheej lubricating uas nthuav tawm cov khoom siv zoo heev thiab kev puas tsuaj nrog rau kev ntxiv dag zog rau lub zog.Ob peb lub khw uas yuav siv cov cwj pwm no yuav yog cov khoom siv hauv qab daus, kev tuav pob, ntim khoom, ua zaub mov thiab tsheb.
Qhov siab molecular hnyav yog dab tsi muab UHMW-PE ib qho kev sib xyaw ua ke ntawm kev ua haujlwm siab ua haujlwm ntawm kev sib txhuam thiab kev puas tsuaj uas tawm ntawm cov hlau 10 mus rau 1 ua rau nws tsim nyog rau cov ntawv thov uas cov qib qis molecular poob.
Muaj peb qhov kev xeem uas koj tuaj yeem ua tau:
- Hlawv Test - teeb nws nrog qhov sib tw thiab hnov cov pa taws.Yog hais tias nws tsw zoo li tswm ciab ciab - uas qhia tias polyethylene.UHMW tsis drip li yooj yim li HDPE tab sis nws yuav drip.
- Qhov cub Test - muab tso rau hauv ib lub tais txhuas hauv qhov cub 300 degree.HDPE tsis tu ncua yuav poob los yog yaj tab sis UHMW yuav tsis hloov qhov loj lossis cov duab.Txawm li cas los xij, nws tuaj yeem cuam tshuam los yog cuam tshuam vim ua rau muaj kev ntxhov siab.
Pom Kev Ntsuas - Thaum txiav nrog cov saw, HDPE ib txwm muab cov sawdust lossis cov ntaub ntawv thaum UHMW muab cov hlua lossis tsis muaj dab tsi.
