Cov khoom ntawm Polyurethane Rubber
Durability thiab Hardness
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm polyurethane roj hmab yog nws qhov ua tau zoo kawg. Nws muaj ntau yam hardness theem, los ntawm tsawg li 20 Shore A mus rau saum toj 80 Shore A, ua rau nws haum rau ntau yam kev siv. Qhov kev hloov pauv hauv qhov nyuaj no tau ua tiav los ntawm cov qauv sib txawv, tso cai rau cov tuam txhab tsim cov khoom siv rau cov kev xav tau tshwj xeeb. Piv txwv li, softer formulations yog zoo tagnrho rau cushioning daim ntaub ntawv, thaum nyuaj variants yog siv nyob rau hauv industrial rollers thiab seals.
Abrasion Resistance
Polyurethane roj hmab excels nyob rau hauv abrasion kuj, outperforming ntau tsoos ntaub ntawv. Nws hnav tsis kam yog 5 mus rau 10 npaug siab dua li ntawm cov roj hmab ntuj lossis lwm cov roj hmab hluavtaws. Cov cuab yeej no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov xws li conveyor siv, gaskets, thiab lub log, qhov kev sib txhuam thiab hnav tsis tu ncua.
Siab Tensile zog
Lub zog tensile ntawm polyurethane roj hmab tuaj yeem ncav cuag 600 kgf / cm², uas yog siab dua li ntawm ntau lwm cov elastomers. Lub zog siab no ua kom ntseeg tau tias cov khoom tuaj yeem tiv taus qhov hnyav thiab kev ntxhov siab yam tsis muaj deforming lossis tawg, ua rau nws zoo tagnrho rau kev thov kev lag luam.
Elasticity thiab qis Residual Deformation
Polyurethane roj hmab nthuav tawm zoo elasticity, nrog cov txheeb ze elongation txog li 600%. Txawm tias nyob rau hauv xws li siab elongation, qhov seem deformation yog tsawg, feem ntau yog li ntawm 2% mus rau 4%. Cov cuab yeej no tseem ceeb heev rau cov ntawv thov uas yuav tsum tau rov ua dua thiab compression, xws li cov ntsaws ruaj ruaj thiab diaphragms.
Roj thiab tshuaj tiv thaiv
Lwm qhov txiaj ntsig tseem ceeb ntawm cov roj hmab polyurethane yog nws cov kev tiv thaiv zoo rau cov roj thiab tshuaj. Nws outperforms nitrile roj hmab nyob rau hauv tsis kam rau cov ntxhia roj thiab yog 5 mus rau 6 lub sij hawm zoo tshaj li cov roj hmab ntuj. Qhov no ua rau nws nyiam cov khoom siv rau hauv ib puag ncig uas raug rau cov roj, roj, thiab lwm yam tshuaj hnyav.
Kev siv ntawm polyurethane roj hmab
Automotive Kev Lag Luam
Nyob rau hauv lub tsheb sector, polyurethane roj hmab yog dav siv rau kev tsim ncua kev kawm ntawv bushings, seals, thiab gaskets. Nws lub peev xwm thauj khoom siab thiab tsis kam hnav ua rau nws zoo tagnrho rau cov ntawv thov no. Tsis tas li ntawd, nws muaj peev xwm tiv taus qhov kub thiab txias kom ntseeg tau tias kev ua tau zoo nyob rau hauv qhov kub thiab txias huab cua.
Kev tsim kho thiab Infrastructure
Polyurethane roj hmab yog siv dav hauv kev tsim kho rau kev siv xws li kev co dampers, flooring, thiab coatings. Nws durability thiab tsis kam mus rau abrasion thiab chemicals ua rau nws ib tug txhim khu kev qha kev xaiv rau hnyav siv puag ncig. Ntxiv mus, nws yooj yooj yim tso cai rau nws nqus shocks thiab vibrations zoo, txhim khu lub neej ntev ntawm cov qauv.
Kev tsim khoom thiab kev siv tshuab
Hauv kev tsim khoom, polyurethane roj hmab yog ua haujlwm hauv cov siv conveyor, rollers, thiab tshuab qhov chaw. Nws lub zog siab thiab hnav tsis kam ua kom ntseeg tau tias cov khoom siv no tuaj yeem ua haujlwm hnyav thiab ua haujlwm tsis tu ncua yam tsis muaj kev hloov pauv ntau zaus. Qhov no tsis yog tsuas yog txo qis lub sijhawm tab sis kuj txo cov nqi kho.
Cov khoom siv
Polyurethane roj hmab kuj muaj nyob rau hauv ntau yam khoom siv, xws li khau, khoom siv ncaws pob, thiab khoom siv hauv tsev. Nws lub teeb yuag, ua ke nrog nws cov kav ntev thiab yoog raws, ua rau nws muaj kev xaiv nrov rau cov ntawv thov no. Piv txwv li, nws yog siv nyob rau hauv cov khau ntawm cov khau kis las uas ua tau zoo los muab cov cushioning thiab kev txhawb nqa.
Xaus
Polyurethane roj hmab sawv tawm raws li cov khoom siv ntau yam thiab txhim khu kev qha uas ua tau raws li qhov xav tau ntawm ntau yam kev lag luam. Nws cov khoom sib xyaw tshwj xeeb, suav nrog lub zog siab, elasticity, thiab tsis kam hnav thiab tshuaj lom neeg, ua rau nws nyiam xaiv rau cov ntawv thov xws li tsheb mus rau cov khoom siv. Rau kev nkag siab tob txog nws cov ntawv thov thiab cov txiaj ntsig, koj tuaj yeem tshawb nrhiav ntau ntxiv txog Polyurethane Roj Hmab.
