Desmodur Re, tseem hu ua Cas 2422-91-5, yog ib qho kev sib txuas ntxiv thiab dav dav. Vim nws cov kev ua tau zoo thiab zoo, nws tau siv dav hauv ntau yam kev lag luam. Hauv tsab xov xwm no, peb tshawb txog kev siv ntawm desmodur thiab paub yog vim li cas nws thiaj nyiam nrov nrog cov tuam ntxhab.
Desmodur re belongs rau tsev neeg uas muaj ntxhiab diisocyanates, compounds dav siv hauv kev tsim cov polyurethane txheej, cov nplaum thiab elastomers. Nws yog lub teeb daj rau amber kua muaj xws li ntawm kev sib xyaw ntawm isomers nrog cov qauv tshuaj sib xws. Lub ntsiab ntawm desmodur re yog toluene diisocyanate (tdi), uas yog siv dav hauv kev tsim cov polyurethane ua npuas ncauj.
Ib qho ntawm lub ntsiab siv ntawmDesmodur reyog nyob rau hauv kev tsim cov polyurethane txheej. Polyurethane txheej muab kev tiv thaiv zoo heev rau kev tiv thaiv xeb, huab cua thiab kev puas tsuaj. Lawv paub txog lawv lub siab ntev thiab ua tau zoo hauv kev hnyav ib puag ncig. Desmodur Re yog qhov tseem ceeb ntawm cov qauv txheej txheem, muab cov khoom siv ua kom muaj zog ntxiv, cov tshuaj nplaum thiab cov tshuaj lom neeg kuj.
Lwm daim ntawv thov tseem ceeb ntawm Desmodur Re yog cov khoom lag luam polyurethane. Polyurethane Adhesives tau siv dav hauv kev siv tsheb, kev tsim kho thiab rooj tog zaum kev lag luam vim lawv lub zog zoo dua thiab versatility. Desmodur rov ua kom muaj zog txhawb nqa lub zog polyurethane, tso cai rau lawv kom ua raws li cov hlau, yas thiab ntoo. Qhov no ua rau lawv zoo tshaj plaws rau kev lamination, kev sib koom tes thiab cov ntawv thov sealing.
Desmodur Re kuj siv tau ntau lawm hauv kev tsim cov polyurethane elastomers. POLYURETHANE EATURETOMERS ua yeeb yam zoo tshaj plaws cov yam ntxwv xws li cov elasticity zoo, kua muag tiv taus thiab puas tsis kam. Lawv tau siv hauv kev lag luam xws li khau, Automotive thiab kev tsim khoom lag luam. Desmodur re plays Lub luag haujlwm tseem ceeb hauv kev sib koom tes ntawm cov elastomers, muab rau lawv nrog lub zog tensile zoo nkauj thiab elongation.
Tsis tas li ntawd,Desmodur reyog paub rau nws cov khoom siv ceev ceev. Qhov no txhais tau tias nws tuaj yeem hla-txuas nrog polyols los ua tus muaj zog polyurethane network. Kev kho lub ntsej muag ceev heev yog qhov xav tau hauv kev lag luam uas yuav tsum muaj lub sijhawm tig rov qab, xws li lub tsheb lossis kev tsim kev lag luam. Tsis tas li ntawd, Desmodur Re muaj qhov zoo sib xws nrog ntau yam ntawm polycs, enabling cov tuam txhab los txiav cov khoom ntawm lawv cov khoom kom muaj cov kev cai tshwj xeeb.
Hauv kev xaus, Desmodur Re (CASE 2422-91-5) yog qhov sib txuas siv dav dav nrog cov kev lag luam loj xws li cov tshuaj pleev xim, cov nplaum thiab elastomers. Nws cov khoom tshwj xeeb, suav nrog kev siv tawv tawv, kev kho kom zoo nkauj thiab kho cov tshuaj nrawm, ua rau nws xaiv tau cov chaw tsim khoom. Txawm hais tias muab kev tiv thaiv corrosion los ntawm polyurethane txheej, ua tiav cov khoom lag luam muaj zog, lossis txhim kho cov khoom ua kom tseem ceeb rau cov ntaub ntawv muaj kev ua haujlwm siab.
