Polyurethane elastomers yog ntau cov khoom siv uas nthuav tawm cov khoom siv zoo xws li elasticity, hnav tsis kam thiab kav ntev. Cov khoom no ua rau lawv haum rau ntau cov ntawv thov kev lag luam, suav nrog cov chaw lag luam, khau, cov duab suav thiab txheej. Kev tsim cov polyurethane elastomers yuav tsum tau kho cov tshuaj lom neeg uas muaj feem cuam tshuam, tshwj xeeb tshaj yog thaum tsim lub urethane txoj kev cog lus nruab nrab ntawm polyol thiab ownocyanate. Polyurethane catalysts ua lub luag haujlwm tseem ceeb ntawm no.
Polyurethane catalystsMuaj peev xwm tswj qhov nrawm thiab ua haujlwm ntawm cov tshuaj tiv thaiv polyurethane. Lawv cuam tshuam qhov sib npaug ntawm gelation (polyol-isocyanate) thiab ua npuas ncauj (dej-ownocyanate) cov tshuaj tiv thaiv cov thaj chaw kawg ntawm Elastomer. Los xaiv cov catalyst txoj cai, cov tuam ntxhab tuaj yeem ua kom zoo ua tiav cov kev mob thiab tailor cov khoom siv lub cev ntawm Elastomer kom tau raws li cov ntawv thov.
Ib qho tseem ceeb catalyst siv nyob rau hauv zus tau los ntawm polyurethane elastomers yog mxc {0}}}} ether (dmau).MXC -37yog qhov qis-tso tawm, qis-ntxhiab amine catalyst uas yog siv dav hauv cov ntawv thov uas yuav tsum muaj cov tshuaj amine tsawg tsawg thiab ua tau zoo. Cov khoom tshwj xeeb ntawm MXC -37} Ua rau nws tsim nyog rau estermers, elastomers ua npuas ncauj, cov tshuaj tiv thaiv kev txhaj tshuaj foam.
MXC -37 hauv polyurethane elastomers
MXC -37muaj ntau cov txiaj ntsig hauv kev tsim cov polyurethane elastomers. Nws yog ib qho kev ua yeeb yam zoo heev uas ua kom cov txheej txheem ua npuas ncauj thiab tau haum zoo rau cov qauv ntsiab lus. Nws cov kev ua npuas dej siab txhawb nqa npuas cov qauv ua npuas thiab cov qauv khoom siv ntawm tes ua ke, uas yog qhov tseem ceeb rau kev siv microcellular ua npuas thiab elastomers.
Hauv Elastomer daim ntaub ntawv, MXC {{0} kev kho cov khoom siv nrawm nrawm thiab ua kom muaj zog, xws li txhim kho tensile zog thiab hloov tau. Qhov no ua rau nws pom zoo rau kev tsim khoom ntawm cov neeg muaj zog loj uas yuav tsum tau elasticomer uas yuav tsum tau elasticity, xws li ntsaws, gaskets thiab qhov chaw tsheb.
Ib qho ntxiv, qhov tsis muaj ntxhiab tsw qab thiab pes tsawg emission thaj chaw ntawm MXC -37}} tseem muaj txiaj ntsig tseem ceeb, tshwj xeeb hauv cov ntawv thov tsw qab. Cov Amine Odor feem ntau txuam nrog polyurethant catalysts yog qhov tsawg thaum siv MXC {2}}}} {2}}
Cov ntawv thov ntau ntau
Cov versatility ntawm MXC -37 tsis muaj txwv rau elastomers, tab sis kuj txuas mus rau lwm lub tshuab polyurethane. Nyob rau hauv microcellular ua npuas application, nws pab tsim cov ua npuas dej nrog cov hws zoo thiab hnav khaub ncaws hnav zoo, uas txhim kho cov khoom poob siab thiab cov khoom poob siab. Hauv kev txhaj tshuaj moulding (ntug), mxc {{1} Pab kom nrawm nrawm, kev ua haujlwm siab rau kev siv tsheb thiab kev siv khoom lag luam.
Tsis tas li ntawd, MXC -37 yuav siv tau rau hauv cov ntaub ntawv sau ua npuas, qhov chaw ua npuas dej siab ua kom muaj kev tiv thaiv zoo thiab kev tiv thaiv. Cov catalyst tus ntxhiab tsw tsawg thiab xoom emission properties kuj tau txais cov cuab yeej siv ib puag ncig thiab kev txhim kho cov haujlwm ua haujlwm ib puag ncig.
