Cov tshuaj polyurethane catalysts ua lub luag haujlwm tseem ceeb hauv kev tsim cov sandwich panels, cov rooj tog ua npuas ncauj ruaj khov thiab cov khoom dai kom zoo nkauj, uas tuaj yeem txhim kho kev ua haujlwm thiab kev ua tau zoo ntawm polyurethane ua npuas ncauj. Cov tshuaj catalysts siv rau hauv cov ntawv thov no yog MXC-8 (DMCHA) thiab MXC-41, ob qho tib si ua rau muaj peev xwm tsim cov npuas dej ruaj khov, sib dua thiab ua tau zoo.
MXC-8 (DMCHA):Ib qho Catalyst uas siv tau ntau yam rau cov ntawv thov ua npuas ncauj ruaj khov
MXC-8, kuj hu uaDMCHA(Dimethylcyclohexylamine), yog ib qho tshuaj catalyst ua los ntawm amine uas siv tau zoo heev hauv kev tsim cov polyurethane ua npuas ncauj, suav nrogcov vaj huam sib luag sandwichthiabcov thav duab rooj tog.
Cov txiaj ntsig tseem ceeb ntawm MXC-8 (DMCHA) hauv kev tsim ua npuas ncauj:
Lub Sijhawm Kho Sai: DMCHA ua kom cov txheej txheem kho ntawm cov polyurethane ua kom sai dua, pab cov chaw tsim khoom ua tiav lub sijhawm tig rov qab sai hauv kev tsim cov ua npuas ncauj tawv, xws likev tsim cov rooj tog zaum.
Cov Qauv Ua Npuas Uas Zoo Dua: MXC-8 ua rau cov hlwb zoo sib xws hauv cov ua npuas ncauj zoo dua, uas ua rau cov hlwb zoo dualub zog compressive thiabkev ruaj khov ntawm qhov ntev ntawm cov khoom kawg. Qhov no tseem ceeb rau cov ntawv thov xws li cov rooj tog ua npuas ncauj ruaj khov, qhov twg kev ua kom ruaj khov yog qhov tseem ceeb rau kev ua kom ruaj khov thiab lub neej ua haujlwm.
Kev Siv Tau Ntau Yam Hauv Cov Ntawv Thov: Ntxiv rau cov vaj huam sib luag sandwich, MXC-8 kuj tseem siv rau hauv lwm cov khoom ua npuas ncauj kho kom zoo nkauj, pab tsim cov khoom sib dua tab sis ruaj khov rau kev tsim cov rooj tog thiab cov khoom vaj khoom tsev. Nws yaj tau hauv feem ntau polyols thiab cov kuab tshuaj organic, tab sis feem ntau tsis yaj hauv dej. Nws tuaj yeem siv ua tus neeg ua kom muaj zog rau ntau yam kev siv suav nrog txhua hom npuas ncauj ntim khoom.
Txo Cov Khib Nyhiab thiab Kev Sib Xws: Los ntawm kev ua kom cov tshuaj tiv thaiv sai dua ntawm covpolyolthiabisocyanatecov khoom sib xyaw, MXC-8 pab tswj cov khoom ua npuas dej kom sib xws, txo cov khib nyiab thiab ua kom cov khoom kawg sib xws.
MXC-41:Muaj Peev Xwm Ua Npuas Ncauj Zoo Tshaj Plaws rau Cov Txheej Txheem Dej-Symbiotic
Lwm qhov tseem ceeb catalyst hauv kev tsim cov polyurethane ua npuas ncauj, tshwj xeeb tshaj yog nyob rau hauvcov vaj huam sib luag sandwich, yogMXC-41Paub txog nws lub peev xwm ua npuas dej zoo heev, MXC-41 muaj txiaj ntsig zoo hauvcov dej-symbiotic hard systems, qhov twg dej siv los tsimCO2roj, txhawb kev nthuav dav ntawm cov ua npuas ncauj thaum lub sijhawm kho.
Cov txiaj ntsig tseem ceeb ntawm MXC-41 hauv kev tsim ua npuas ncauj:
Muaj Peev Xwm Ua Npuas Ncauj Zoo heev: MXC-41 ua haujlwm tau zoo hauv cov tshuab uas siv dej ua tus neeg sawv cev ua npuas ncauj, ua kom ntseeg tau tias ua npuas ncauj nthuav dav zoo thiab sib npaug. Lub peev xwm ua npuas ncauj no yog qhov tseem ceeb rau kev tsim cov vaj huam sib luag sandwich, vim tias cov qauv cellular sib npaug yog qhov tseem ceeb rau ob qho tib si thermal rwb thaiv tsev thiab lub zog kho tshuab.
Cov Khoom Siv Txhim Kho Dua: Cov khoom ua npuas ncauj ntawm cov catalyst pab tsim cov npuas dej tawv uas tsis yog tsuas yog lub teeb hauv qhov hnyav xwb tab sis kuj muaj peev xwm nqa tau siab thiab lub zog compressive, ua rau lawv yog qhov kev xaiv dav rau cov qauv siv xws li sandwich panels thiab cov rooj tog zaum.
