Desmodur RE, tseem hu ua CAS 2422-91-5, yog ntau yam thiab siv dav siv. Vim nws txoj kev ua tau zoo thiab qhov zoo, nws tau siv dav hauv ntau yam kev lag luam. Hauv tsab xov xwm no, peb tshawb nrhiav kev siv Desmodur thiab nrhiav seb vim li cas nws thiaj li nrov nrog cov tuam ntxhab.
Desmodur RE belongs rau tsev neeg ntawm aromatic diisocyanates, cov tebchaw dav siv nyob rau hauv zus tau tej cov polyurethane txheej, adhesives thiab elastomers. Nws yog lub teeb daj rau cov kua amber uas muaj kev sib xyaw ntawm isomers nrog cov qauv tshuaj zoo sib xws. Cov khoom tseem ceeb ntawm Desmodur RE yog toluene diisocyanate (TDI), uas yog dav siv nyob rau hauv zus tau tej cov polyurethane ua npuas ncauj.
Ib qho ntawm cov kev siv tseem ceeb ntawmDesmodur REyog nyob rau hauv kev tsim ntawm polyurethane txheej. Polyurethane coatings muab kev tiv thaiv zoo heev tiv thaiv corrosion, huab cua thiab puas. Lawv paub txog lawv cov kev ua haujlwm siab thiab kev ua haujlwm zoo hauv qhov chaw hnyav. Desmodur RE yog qhov tseem ceeb hauv cov txheej txheem txheej txheej no, ua rau lawv muaj zog ntxiv, adhesion thiab tshuaj tiv thaiv.
Lwm daim ntawv thov tseem ceeb ntawm Desmodur RE yog kev tsim cov nplaum polyurethane. Polyurethane adhesives yog dav siv nyob rau hauv tsheb, kev tsim kho thiab rooj tog kev lag luam vim lawv superior bond zog thiab versatility. Desmodur RE txhim kho lub zog ntawm daim ntawv cog lus ntawm polyurethane nplaum, tso cai rau lawv ua raws li ntau yam substrates xws li hlau, yas thiab ntoo. Qhov no ua rau lawv zoo tagnrho rau kev siv lamination, kev sib txuas thiab kev sib khi.
Desmodur RE kuj tseem siv rau hauv kev tsim cov polyurethane elastomers. Polyurethane elastomers muaj cov khoom siv zoo heev xws li siab elasticity, tsim kua muag tsis kam thiab puas ua haujlwm. Lawv yog siv nyob rau hauv kev lag luam xws li khau, automotive thiab industrial manufacturing. Desmodur RE ua lub luag haujlwm tseem ceeb hauv kev sib txuas ntawm cov elastomers, muab lawv lub zog tensile zoo thiab elongation zog.
Tsis tas li ntawd,Desmodur REyog paub txog nws ceev curing zog. Qhov no txhais tau tias nws tuaj yeem sib txuas tau sai nrog polyols los tsim ib lub zog polyurethane network. Kev kho sai sai yog qhov xav tau nyob rau hauv kev lag luam uas xav tau lub sijhawm hloov pauv sai, xws li kev lag luam tsheb lossis kev tsim kho. Tsis tas li ntawd, Desmodur RE muaj kev sib raug zoo nrog ntau yam ntawm polyols, ua rau cov tuam txhab tsim kho cov khoom ntawm lawv cov khoom rau cov kev cai tshwj xeeb.
Hauv kev xaus, Desmodur RE (CAS 2422-91-5) yog cov khoom siv dav siv nrog kev siv dav hauv kev lag luam xws li coatings, adhesives thiab elastomers. Nws cov khoom tshwj xeeb, suav nrog kev txhim kho hardness, adhesion thiab kho sai, ua rau nws yog qhov kev xaiv nrov ntawm cov tuam ntxhab. Txawm hais tias muab kev tiv thaiv corrosion los ntawm polyurethane coatings, ua tiav cov ntawv cog lus muaj zog hauv cov nplaum, lossis txhim kho cov khoom siv hluav taws xob ntawm elastomers, Desmodur RE tau ua pov thawj tias yog ib qho tseem ceeb hauv kev tsim cov ntaub ntawv ua tau zoo.
