Polyurethane elastomerstau dav lees paub rau lawv cov kev hnav zoo heev, muaj peev xwm thauj khoom siab, yoog raws, thiab lub neej ua haujlwm ntev. Lawv yog siv nyob rau hauv kev lag luam xws li mining, kev tsim kho, kev thauj mus los, machinery, automotive, thiab cov khoom tuav. Vim tias polyurethane elastomers tuaj yeem tsim nrog cov khoom sib txawv thiab kev tsim khoom, kev nkag siab txog lawv cov kev faib tawm yog qhov tseem ceeb thaum xaiv cov khoom siv rau ib daim ntawv thov tshwj xeeb.
Txoj hauv kev zoo tshaj plaws los faib cov polyurethane elastomers yog raws li lawv cov txheej txheem tsim khoom.
Cam khwb cia polyurethane elastomer, feem ntau hu ua CPU, yog hom siv dav tshaj plaws rau kev lag luam hnyav. Nws yog tsim los ntawm reacting ib polyurethane prepolymer nrog ib tug saw extender thiab ces casting cov khoom rau hauv pwm.
Cam khwb cia polyurethane muaj kev tiv thaiv zoo heev, siab tensile zog, zoo heev load- bearing peev, thiab ntev lub neej qaug zog. Nws yog tsim rau kev tsim khoom loj thiab tuab qhov chaw uas xav tau kev ua haujlwm zoo tshaj plaws.
Cov ntawv thov xws li polyurethane rollers, log, mining screen panels, scraper blades, bushings, couplings, seals, industrial pads, and other custom wear parts.
Thermoplastic polyurethane, feem ntau hu ua TPU, tuaj yeem yaj thiab ua tiav ntau zaus los ntawm kev txhaj tshuaj molding lossis extrusion. Piv nrog cam khwb cia polyurethane, TPU muaj kev ua haujlwm zoo thiab rov ua dua tshiab.
TPU yog dav siv rau cov tsho cable, hoses, cov khau khau, cov khoom siv tsheb, cov khoom siv hluav taws xob, thiab cov khoom siv kho mob qhov yooj yim thiab zoo li qhov tseem ceeb.
Millable polyurethane, los yog MPU, yog ua tiav siv cov khoom siv roj hmab tsoos xws li kev sib xyaw mills thiab vulcanization systems. Txawm hais tias nws txoj kev lag luam feem ntau me me, nws tseem yog siv rau qee yam khoom siv sealing thiab cov khoom siv roj hmab tshwj xeeb.
Polyurethane elastomers kuj raug cais raws li hom polyol siv thaum tsim khoom.
Polyether polyurethane yog tsim los ntawm polyether polyols. Nws paub zoo tias nws zoo heev hydrolysis tsis kam, tsis tshua muaj kub yooj, thiab tsis kam mus ya raws thiab microbial nres.
Cov txiaj ntsig zoo no ua rau polyether polyurethane yog qhov kev xaiv zoo tshaj plaws rau qhov chaw ntub dej thiab kev siv sab nraum zoov. Nws yog feem ntau siv rau hauv cov khoom siv mining, marine Cheebtsam, conveyor systems, chaw nres nkoj machinery, thiab hnyav- lub luag hauj lwm muaj log.
Polyester polyurethane yog tsim los ntawm polyester polyols. Piv nrog cov tshuab polyether, nws feem ntau muab cov khoom siv zog ntau dua, cov roj ua haujlwm zoo dua, thiab txhim kho kev ua haujlwm rau ntau cov kuab tshuaj.
Polyester polyurethane yog dav xaiv rau luam ntawv rollers, industrial rollers, roj -cov ntsaws ruaj ruaj, thiab precision mechanical Cheebtsam. Txawm li cas los xij, feem ntau nws tsis tshua muaj kev tiv thaiv ntev ntev - lub sij hawm raug dej noo dua li polyether polyurethane.
Hom isocyanate siv kuj muaj qhov cuam tshuam tseem ceeb ntawm cov khoom kawg ntawm polyurethane elastomers.
MDI raws li polyurethane systems tau dhau los ua tus qauv kev lag luam vim lawv muab qhov sib npaug zoo ntawm kev ua cov yam ntxwv, txhua yam muaj zog, thiab kav ntev.
TDI raws li polyurethane systems tau siv ntau xyoo thiab tseem nrov nyob rau hauv ntau yam cam khwb cia polyurethane daim ntaub ntawv vim lawv txhim khu kev qha kev ua tau zoo.
PPDI raws li polyurethane muaj kev ua tau zoo ntawm kev ua haujlwm zoo, kev ua haujlwm zoo, thiab kev qaug zog zoo dua, ua rau nws tsim nyog rau kev thov kev siv engineering.
NDI raws li polyurethane muab tshwj xeeb kub ua haujlwm thiab kev puas tsuaj rau hnyav -cov haujlwm ua haujlwm ib puag ncig uas lub neej ua haujlwm ntev yog qhov tseem ceeb.
Xaiv txoj cai polyurethane elastomer yog nyob ntawm ntau yam, suav nrog kev ua haujlwm kub, kev thauj khoom txhua yam, hnav khaub ncaws, raug dej, roj, lossis tshuaj lom neeg, thiab kev tsim khoom.
Rau cov ntawv thov uas xav tau kev ua haujlwm zoo hydrolysis thiab kev ua haujlwm sab nraum zoov, polyether polyurethane feem ntau yog cov tshuaj uas nyiam. Thaum xav tau roj ntau dua thiab lub zog txhua yam, polyester polyurethane yuav yog qhov kev xaiv zoo dua. Rau cov khoom lag luam loj uas xav tau kev hnav, cam khwb cia polyurethane elastomers feem ntau xa cov kev ua tau zoo tshaj plaws.
Ua haujlwm nrog cov chaw tsim khoom polyurethane uas muaj kev paub dhau los tuaj yeem pab ua kom cov ntaub ntawv tsim tau zoo raws li qhov tshwj xeeb ntawm koj daim ntawv thov.
