Polyurethane prepolymer yog cov khoom siv elastomer feem ntau siv rau cov menyuam. Polyurethane prepolymer muaj peev xwm ua tau ntau yam kev sib xyaw los ntawm ntau hom thiab feem ntau ntawm nws cov khoom xyaw sib xyaw. Los ntawm kev sib xyaw, cov khoom sib txawv ntawm cov khoom siv kho tshuab tau txais kom haum rau ib qho kev siv. Cov khoom zoo tshaj plaws ntawm polyurethane yog nws qhov toughness, siab impingement kuj, poob siab absorbing, thiab qaug zog kuj.
Lifespan: Polyurethane rollers dhau 4,000 teev, cov roj hmab tawm ntawm 1,000 teev.
Mechanical Strength: Resistant kua muag thiab crushing, ua kom lub neej ntev kev pab cuam.
Chemical Resistance: Siv tau rau cov roj, cov kuab tshuaj, thiab qee cov acids / bases, haum rau ntau yam lag luam.
Kev Ua Haujlwm Kub Kub: Ua haujlwm txog 80 degree thiab tiv taus luv luv ntawm 120 degree.
Environmental Adaptability: Polyurethane rollers tuaj yeem tiv taus UV, ozone, thiab roj, zoo tagnrho rau kev siv sab hauv tsev thiab sab nraum zoov.
Polyurethane rollers ua tau zoo hauv kev txhawb nqa hnyav. Lawv lub zog los ntawm Molecular Structure: Polyurethane yog tsim los ntawm cov saw hlau uas muaj zog uas muab nws lub zog thiab yooj, cia cov menyuam nqa hnyav yam tsis muaj deforming.
BQ1231 yog raws li Polyester thiab TDI Polyurethane prepolymer. Cov khoom siv tau dav siv hauv:
Kev tsim khoom: Polyurethane rollers streamline sib dhos kab thiab automation, txhim kho kev ua haujlwm zoo thiab cov menyuam ua haujlwm ntev.

Kev ua zaub mov: Hais txog kev nyiam huv thiab FDA cov qauv, Polyurethane rollers yog qhov tseem ceeb hauv ob qho tib si ua thiab ntim cov theem.
Aviation: Ua hauj lwm hauv aircraft tsim thiab tu, lawv lub xub ntiag ua kom muaj tseeb thiab kev cia siab.
Ntim: Cov rollers no pab tswj cov khoom sib txawv thiab txhawb nqa kev ua tau zoo hauv cov txheej txheem ntim nrawm.
Printing: Qhov tseem ceeb hauv cov tshuab luam ntawv, polyurethane rollers kom cov xim raug thiab ua haujlwm siab.
Kev Ua Liaj Ua Teb: Pom nyob rau hauv cov cuab yeej ua liaj ua teb niaj hnub thiab cov kav dej, lawv txhawb kev ua liaj ua teb txiav.
Kev Lag Luam: Ib qho tseem ceeb hauv kev ua cov ntaub ntawv thiab ATMs, txhim kho ob qho kev ntsuas kev nyab xeeb thiab kev ua haujlwm zoo.
Kev tsim kho: Siv hauv kev tswj cov khoom siv thiab kev siv tshuab, lawv pab hauv kev tsim kho kev tsim kho.
Hlau Txiav: Siv rau kev txiav thiab kev tswj cov khoom siv zoo, lawv cov kev puas tsuaj ua rau lub neej ua haujlwm ntev.
Sib piv cov txheej txheem: Polyurethane Vs Rubber Rollers

Tsawg resistant piv rau polyurethane. |
|
Kev ntub dej ib puag ncig tsim nyog |
Resistant mus rau degradation, txawm tias thaum submerged los yog raug rau ya raws. |
Yooj yim rau rotting los yog degrading nyob rau hauv damp tej yam kev mob. |
|
Tshuaj muaj pes tsawg leeg |
Muab chav rau kev cai formulations, yoog raws cov kev xav tau tshwj xeeb. |
Tej zaum yuav raug hloov nrog cov fillers tshwj xeeb, tab sis nkag siab rau qee yam tshuaj. |
|
Propensity to Leave Marks |
Cov cuab yeej tsis yog cim ua kom cov khoom sib kis tsawg tsawg. |
Nws muaj lub siab nyiam tawm cov qhab nia, tshwj xeeb tshaj yog rau cov khoom muag. |
|
Manufacturing & Industrial Siv |
Versatile thiab dav siv nyob rau hauv ntau yam manufacturing txheej txheem. |
Ntev-sawv keeb kwm nyob rau hauv ntau industries. |
|
Environmental Impact |
Raws li kev tsim qauv, qee hom yuav ua rau eco-phooj ywg ntau dua. |
Feem ntau, muaj qhov loj dua ib puag ncig hneev taw, tshwj xeeb tshaj yog tias tsis rov siv dua. |
|
Nqi |
Feem ntau pib nqis peev ntau dua li roj hmab. |
Feem ntau tsis tshua kim pib tab sis yuav ua rau tus nqi nyob rau lub sijhawm ntev vim muaj teeb meem kav ntev. |
