Cov polyurethane catalyst kev lag luam plays qhov tseem ceeb ntawm kev tsim cov polyurethane ua npuas, ua rau cov neeg tsim khoom siv ua kom zoo nkauj, ua npuas ncauj, thiab cov khoom lag luam zoo kawg nkaus. Polyurethane catalysts yog qhov tseem ceeb hauv kev tsav tsheb ntawm cov tshuaj lom neeg, xws li ua npuas ncauj, thiab ua npuas dej kom huv, yog tsim nrog cov yam ntxwv xav tau thiab cov khoom ntiag tug. Kev xaiv ntawm catalysts muaj cuam tshuam ntau cov efficiency, zoo, thiab ib puag ncig profile ntawm lub tshuab ua npuas ncauj.
Hom Polyurethane catalysts
Polyurethane catalysts tuaj yeem nthuav dav ua ob hom:
Amine catalysts
Amine catalysts yog siv dav hauv kev lag luam polyurethane ua npuas ncauj, tshwj xeeb hauv cov ntawv siv ua npuas ncauj, thiab cov ntawv thov elastomer. Lawv pab tswj hwm qhov sib npaug ntawm lub tshuab thiab kev tawm tsam. Cov catalysts tshwj xeeb yog tsim nyog rau cov ntawv thov uas xav tau precision hauv kev ua tus qauv huab tais thiab cov neeg kho tshuab thev naus laus zis.
Piv Txwv: MXC-RE13
MXC-re13 yog ib qho kev ntsuas amine nrog rau cov ntawv thov ntau yam. Nws yog siv nyob rau hauvester-ruaj khov ua npuas, uas yog qhov tseem ceeb rau cov ntawv thov uas xav tau kev ua tiav thiab kev nplij siab, xws li rooj tog thiab txaj. MXC-re13 kuj tseem ua haujlwm hauvUa npuas ncauj microporous, uas yog lub teeb yuag thiab rov ua dua, ua kom haum rau cov ntawv thov xws li lub rooj zaum automotive xws li automotive zaum. Txuas ntxiv, nws yog siv nyob rau hauvelastomers, muab kev elasticity zoo thiab tawv.
Hlau Catalysts
Hlau catalysts, ntawm qhov tod tes, txhawb nqa polymerization (gelling) thiab crosslinking (kho) cov tshuaj tiv thaiv nyob rau hauv polyurethane tshuab. Cov catalysts feem ntau hloov cov tshuab ua cov tsoos, tshwj xeeb yog cov kev cai ib puag ncig uas xav tau txo cov hlau hnyav, xws li cov mercury, ua, lossis dibutyltin.
Piv Txwv: MXC-B20
MXC-B20 yog ib qho kev sib txuas ntawm cov hlau uas ua rau muaj lwm txoj hauv kev ua kom muaj kev ywj pheej rau cov khoom siv tinalysts. Nwstsis muaj mercury, txhuas, lossis dibutyltin, uas yog qhov tseem ceeb tshaj plaws nyob rau hauv cov ntsiab lus ntawm kev nruj ib puag ncig cov qauv. MXC-B20 cov khoom pov thawjtsis tshua muaj volatilitythiabTsawg Tsawg Tus ntxhiab tsw, kom ntseeg tau ob qho tib si kev nyab xeeb thiab kev ua haujlwm. Nws yog ib qho kev tsim kho rauSaj zawg zog cov ntawv, High-tensity flexible foams, Txau Foams, thiabRigid FoamsCov. Nws qhov kev sib raug zoo nrog ntau yam ntawm cov qauv ua rau nws xaiv tau qhov kev xaiv zoo hauv cov ntawv thov kev ua haujlwm zoo thiab hauv eco phooj ywg.
Daim Ntawv Thov Cov Polyurethane catalysts
Polyurethane catalysts yog qhov tseem ceeb nyob rau hauv kev tsim cov hom ua npuas dej, txhua tus nrog cov ntawv thov sib txawv hauv kev lag luam xws li kev tsim kho:
Flexible Ua Npuas Ncauj
Saj zawg zog polyurethane ua npuass yog mos, resilient cov ntaub ntawv feem ntau siv hauv kev siv cov ntaub ntawv Cushioning xws li rooj tog, thiab tsheb zaum. Amine catalysts zoo li MXC-re13 yog siv los ua kom zoo nkauj ua npuas ncauj lub tsev ua npuas ncauj, muab kev nplij siab zoo dua qub thiab ua kom zoo dua qub. Tus esteer-borter cheatricizers ua kom muaj kev ua tau zoo ntev, txawm tias hauv qab kev ntxhov siab.
Txhav npuas
Rigid Polyurethane ua npuas tsiaj yog tus cwj pwm los ntawm lawv cov peev txheej siab thiab cov qauv nruj. Lawv feem ntau siv nyob rau hauvkev tsa tsev(rwb thaiv tsev panels, vov ru tsev) thiabkhoom siv khoom(Tub yees, khov). Catalysts zoo li MXC-B20 txhim kho cov npuas dej kho, txhim khoThermal rwb thaiv tsevThiab cov txheej txheem kev ntseeg siab thaum txo cov pa hluav taws xob cuam tshuam nrog cov khoom siv hlau hlau.
Txau Npuas
Txau polyurethane ua npuas ncauj (SPF) tau siv dav siv hauv kev tsim kho rwb thaiv tsev thiab cov ntaub ntawv vov tsev, muab hluav taws xob ua kom haum thiab siv hluav taws xob. Ob qho tib si amine thiab hlau catalysts tau siv los tswj cov npuas dej sawv ntsug, cov nplaum kom substrates, thiab kho lub sijhawm. MXC-B20, piv txwv li, txhim kho SPF tshuab los ntawm kev txhawb nqa ceev uas muaj kev cuam tshuam tsis zoo ntawm cov hlau uas muaj cov catalysts.
Tag
Cov polyurethane catalyst kev lag luam yog qhov kev ua tau tseem ceeb ntawm kev ua yeeb yam ntawm polyurethane ua npuas ncauj tshuab, seb puas yog rau kev hloov pauv, lossis ua npuas ncauj. Raws li kev lag luam nce qib rau kev ruaj khov, kev loj hlob ntawmTsawg-emission, Tsawg-ntxhiab, thiabHnyav-Hlau-Dawbcatalysts zoo li MXC-B20 tau ua ntau qhov tseem ceeb. Cov kev nrhav kom ntseeg tau tias cov polyurethane cov khoom tau raws li kev tswj hwm uas tsim nyog rau cov ntawv thov niaj hnub no.
