Kev Taw Qhia
Polyurethane elastomers yog ib pawg ntawm cov polymers uas siv tau ntau yam, ua tau zoo heev uas siv thoob plaws hauv kev lag luam xws li tsheb, kev tsim kho, khau, thiab kev tsim khoom lag luam. Lawv qhov kev sib xyaw ua ke ntawm kev tawv, kev ywj pheej, thiab kev tiv thaiv tshuaj lom neeg ua rau lawv zoo tagnrho rau cov chaw nyuaj. Ib qho tseem ceeb, feem ntau tsis quav ntsej hauv kev tsim cov polyurethane elastomers zoo yog lub kaw lus catalyst - tshwj xeeb tshaj yog amine catalysts, uas pab tswj cov tshuaj tiv thaiv thiab cov khoom kawg ntawm cov khoom.
Ntawm MINGXU NEW MATERIALS, peb tshwj xeeb hauv kev tsim cov tshuaj polyurethane catalysts ua tau zoo. Ib qho ntawm peb cov khoom lag luam tseem ceeb, MXC-37 (DMAEE), ua lub luag haujlwm tseem ceeb hauv ntau yam kev siv elastomer los ntawm kev txhim kho cov tshuaj tiv thaiv kinetics thaum ua kom muaj kev tso pa tawm tsawg thiab tsw ntxhiab tsawg.
Cov tshuaj Polyurethane Catalystshauv Elastomer Systems
Hauv cov qauv polyurethane elastomer, cov catalysts tswj tus nqi ntawm ob qho kev tshuaj tiv thaiv thawj zaug:
1. Qhov kev sib xyaw ua ke (polyol thiab isocyanate)
2. Qhov kev ua kom tawg (dej thiab isocyanate)
Tsis zoo li cov ua npuas dej, cov elastomers feem ntau xav tau kev tshuab tsawg kawg nkaus kom tswj tau qhov ruaj khov ntawm cov qauv. Txawm li cas los xij, hauv qee daim ntawv thov xws li microcellular elastomers lossis tshuaj txhaj tshuaj molding (RIM), qhov sib npaug zoo ntawm kev ua npuas dej thiab gelling yog qhov tseem ceeb rau kev ua tiav qhov ceev, kev ywj pheej, thiab qhov tiav ntawm qhov chaw.
MXC-37 (DMAEE)Ib qho Amine Catalyst Ua Haujlwm Zoo rau Elastomers
MXC-37, tseem hu ua 2-dimethylaminoethylethanol (DMAEE), yog ib qho tertiary amine catalyst uas tsim los muab kev ua tau zoo tshaj plaws hauv elastomer thiab microcellular systems. Nws muaj txiaj ntsig zoo tshwj xeeb hauv cov formulations uas muaj dej ntau, qhov twg ob qho tib si kev tswj kev ua npuas ncauj thiab kev tswj tsw yog qhov tseem ceeb.
Cov txiaj ntsig tseem ceeb ntawm MXC-37 hauv Elastomers:
Tsis Muaj Tsw Qab, Tsis Muaj Pa Tawm Tsim:Ua ib qho tshuaj catalyst uas tsis ua rau muaj pa phem thiab tsis muaj ntxhiab tsw phem, MXC-37 txo cov ntxhiab tsw ntawm cov amine hauv cov khoom elastomer uas ua tiav lawm—tshwj xeeb tshaj yog qhov tseem ceeb hauv cov khoom siv sab hauv tsheb thiab cov khoom siv rau cov neeg siv khoom.
Kev Ua Npuas Ncauj Siab:Txawm tias nyob rau hauv cov kab ke elastomer uas muaj cov ua npuas dej tsawg lossis tswj tau, MXC-37 txhawb nqa cov qauv cell sib xws thiab kev tswj qhov ceev zoo thaum xav tau cov teebmeem microcellular.
Kev Sib Tw Zoo Kawg Nkaus:MXC-37 siv tau nrog ntau hom polyester thiab polyether, ua rau nws haum rau ob qho tib si elastomers mos thiab tawv, nrog rau ester-based stabilizer mos ua npuas ncauj thiab cov khoom ntim khoom ua npuas ncauj tawv.
Kev Siv Tau Ntau Yam: Feem ntau siv rau hauv:
Cov microcellular polyurethane elastomers (piv txwv li, cov hauv qab khau, cov chaw so tes)
RIM systems (tsheb bumpers, panels)
Cov ua npuas ncauj elastomer uas muaj zog heev
Cov khoom siv ntim khoom thiab cov khoom siv rwb thaiv tsev elastomers
Vim li cas ho xaiv MXC-37 rau koj lub Elastomer System?
Kev tsim cov polyurethane elastomers ua tau zoo yuav tsum muaj kev ua kom raug, kev sib xws, thiab kev tswj hwm. MXC-37 muab tag nrho cov no thaum pab cov neeg tsim khoom ua tau raws li cov qauv kev noj qab haus huv ib puag ncig thiab kev ua haujlwm nruj dua. Txawm hais tias koj tab tom tsim cov khoom siv tsheb sib dua lossis cov khoom siv lag luam ruaj khov, MXC-37 txhim kho ob qho tib si cov txheej txheem thiab cov khoom zoo.
Xaus lus
Raws li qhov kev thov rau cov polyurethane elastomer systems uas huv dua thiab ua haujlwm tau zoo dua txuas ntxiv mus, kev xaiv cov catalyst zoo yog qhov tseem ceeb dua puas tau. MXC-37 (DMAEE) muab kev ua tau zoo, kev ua raws li ib puag ncig, thiab kev hloov pauv tau raws li qhov xav tau los ua kom tau raws li cov kev xav tau niaj hnub no.
Tiv tauj peb hnub no kom paub seb MXC-37 tuaj yeem ua kom koj cov polyurethane elastomer zoo dua li cas.
