Desmodur RE:Kawm txog kev siv thiab cov txiaj ntsig ntawm isocyanates
Desmodur REyog ib yam khoom uas muaj nyob rau hauv qeb isocyanate, tshwj xeeb yog tsim los ntawm CAS 2422-91-5. Isocyanates yog cov khoom xyaw tseem ceeb hauv kev tsim khoom ntawm ntau yam khoom siv polyurethane, thiab Desmodur RE tsis muaj qhov tshwj xeeb. Kab lus no yog tsim los muab kev nkag siab tob txog Desmodur RE, nws siv thiab qhov zoo uas nws muaj nyob rau hauv ntau daim ntawv thov.
Desmodur REyog ib qho aliphatic polyisocyanate raws li hexamethylene diisocyanate (HDI). Nws feem ntau yog siv los ua cov khoom siv tawv tawv hauv lub teeb-ruaj khov polyurethane txheej thiab cov ntawv nplaum. Qhov tshwj xeeb chemistry ntawm Desmodur RE ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau cov txheej txheem ua haujlwm siab nrog huab cua zoo thiab tshuaj lom neeg. Tsis tas li ntawd, nws txoj kev sib raug zoo nrog ntau yam ntawm polyols thiab cov kuab tshuaj ntxiv txhim kho nws cov versatility nyob rau hauv ntau formulations.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawmDesmodur REyog nws lub peev xwm los qhia txog kev ua haujlwm zoo thiab UV tsis kam rau txheej txheej. Qhov no ua rau nws tshwj xeeb tshaj yog haum rau kev siv sab nraum zoov, qhov twg raug rau ib puag ncig hnyav tuaj yeem ua rau kev ua haujlwm ntawm cov txheej txheem ib txwm ua. Txawm hais tias siv rau hauv cov txheej txheem tsheb, cov txheej txheem kev lag luam lossis cov vaj tsev ua tiav, Desmodur RE ua lub luag haujlwm tseem ceeb hauv kev txhim kho lub neej ntev thiab zoo li ntawm cov chaw coated.
Ntxiv rau nws lub luag haujlwm hauv txheej txheej, Desmodur RE kuj tseem siv los tsim cov nplaum nplaum zoo. Nws cov cuab yeej kho tau sai thiab zoo heev adhesion rau ntau yam substrates ua rau nws yog ib qho tseem ceeb muaj nyob rau hauv structural adhesives, laminating adhesives thiab sealant formulations. Desmodur RE adhesives muaj peev xwm tiv taus txhua yam kev ntxhov siab thiab ib puag ncig, ua rau lawv thawj qhov kev xaiv rau kev thov kev sib txuas lus hauv kev lag luam sib txawv.
Ntxiv rau,Desmodur REmuab cov qauv tsim muaj peev xwm los hloov kho cov khoom ntawm polyurethane coatings thiab nplaum rau cov kev cai tshwj xeeb. Los ntawm kev kho cov qauv kev faib ua feem thiab koom nrog Desmodur RE, ntau yam kev ua tau zoo tuaj yeem ua tiav, suav nrog hardness, yoog raws thiab tshuaj tiv thaiv. Qhov kev hloov kho theem no ua rau cov tuam txhab ua kom tau raws li cov kev xav tau sib txawv ntawm cov neeg siv kawg hauv cov haujlwm xws li tsheb thiab aerospace mus rau kev tsim kho thiab kev tsim kho vaj tse.
Nws yog ib qho tseem ceeb kom nco ntsoov tias thaumDesmodur REmuaj ntau yam zoo nyob rau hauv cov nqe lus ntawm kev ua tau zoo thiab versatility, vim hais tias ntawm reactive xwm ntawm isocyanates, kev tuav kom raug thiab kev ceev faj yuav tsum tau soj ntsuam. Kev cuam tshuam rau isocyanates tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv, yog li nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov lus qhia txog kev nyab xeeb thiab siv cov cuab yeej tiv thaiv tus kheej tsim nyog thaum tuav Desmodur RE thiab lwm yam khoom siv isocyanate.
Hauv cov ntsiab lus,Desmodur REyog ib qho tseem ceeb muaj nyob rau hauv formulation ntawm high-performance polyurethane coatings thiab nplaum. Nws qhov tshwj xeeb ruaj khov, UV tsis kam thiab versatility ua rau nws muaj qhov tseem ceeb hauv kev tsim cov coatings thiab cov nplaum rau ntau yam kev siv. Los ntawm kev nkag siab txog kev siv thiab cov txiaj ntsig ntawmDesmodur RE, cov tuam ntxhab thiab cov neeg siv khoom kawg tuaj yeem siv nws lub peev xwm los tsim cov khoom siv ruaj khov, kav ntev thiab zoo polyurethane. Txawm li cas los xij, thaum ua haujlwm nrog cov khoom isocyanate, nws yog ib qho tseem ceeb uas yuav tsum tau ua qhov tseem ceeb ntawm kev ntsuas kev nyab xeeb kom ntseeg tau tias kev noj qab haus huv ntawm cov neeg ua haujlwm thiab ib puag ncig.
