Lub luag haujlwm ntawm Catalyst:Hauv cov tshuab ua npuas dej uas yoog tau, cov tshuaj catalysts pab sib npaug cov tshuaj gelling (polyol-isocyanate) thiab cov tshuaj blowing (water-isocyanate) los tsim cov qauv cell zoo sib xws, mos muag, thiab muaj zog zoo. Cov khoom zoo liMXC-37 (DMAEE)thiab MXC-A1 (BDMAEE) muaj cov pa phem tsawg thiab tswj tau cov tshuaj tiv thaiv zoo heev, ua rau lawv zoo tagnrho rau kev lag luam tsheb thiab cov chaw pw uas VOC ua raws li qhov tseem ceeb.
2. Ua Npuas Ncauj Polyurethane Rigid
Cov ntawv thov:Cov tub yees, cov tub yees khov, cov vaj huam sib luag, cov laug cam rwb thaiv tsev, cov yeeb nkab rwb thaiv tsev.
Lub luag haujlwm ntawm Catalyst:Cov ua npuas ncauj ruaj khov xav tau qhov ua kom sai thiab ruaj khov. Cov tshuaj catalysts xws li MXC-15 (Potassium Octanoate) thiab MXC-T12 (Dibutyltin Dilaurate) ua kom muaj kev hloov pauv siab thiab muaj zog. Cov no yog qhov tseem ceeb hauv kev thauj khoom txias, kev rwb thaiv tsev hauv tsev, thiab kev tsim khoom siv.
3. Tshuaj tsuag Polyurethane Ua Npuas Ncauj (SPF)
Cov ntawv thov:Kev rwb thaiv tsev, cov txheej txheem ru tsev, kev txhaws qhov.
Lub luag haujlwm ntawm Catalyst:Cov txheej txheem SPF xav tau kev tswj hwm kom meej rau lub sijhawm ua kom pleev xim, lub sijhawm sawv, thiab lub sijhawm tsis muaj tack. Peb cov catalysts xws li MXC-R40 thiab MXC-MB20 yog qhov zoo tshaj plaws rau cov txheej txheem HFO, muab cov ntxhiab tsw qis thiab kho sai nrog kev nplaum zoo heev. Cov khoom no siv dav hauv cov ntawv thov kev tsim kho kom ruaj khov rau kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig.
4. Polyisocyanurate (PIR) Ua Npuas Ncauj Panels
Cov ntawv thov:Cov vaj huam sib luag sandwich rau phab ntsa, qab nthab, thiab chav cia khoom txias.
Lub luag haujlwm ntawm Catalyst:Cov txheej txheem ua npuas ncauj PIR xav tau cov catalysts uas txhawb nqa trimerization kom zoo dua tiv taus hluav taws thiab ua haujlwm thermal. Peb MXC-TMA yog tsim tshwj xeeb los txhawb cov qauv cell sib xws thiab muaj zog tom qab kho, tsim nyog rau ob qho tib si txuas ntxiv thiab tsis txuas ntxiv cov kab ntau lawm.
5. Microcellular Ua Npuas Ncauj thiab Elastomers
Cov ntawv thov:Cov khau nruab nrab, lub log tsheb, cov vaj huam sib luag ntsuas, cov khoom siv co.
Lub luag haujlwm ntawm Catalyst:Cov ntawv thov no xav tau cov tshuaj catalysts uas muab cov tshuaj tiv thaiv qeeb rau kev sau pwm thaum ua kom muaj zog kawg. Cov kev daws teeb meem zoo li MXC-R70 thiab MXC-B20 muab kev sib npaug zoo heev ntawm kev ntws thawj zaug thiab kev kho zaum kawg, txhim kho cov khoom sib xws thiab kev ua haujlwm zoo.
6. Cov Khoom Siv Nplaum Thiab Cov Khoom Siv Sib Txuas Ob Yam
Cov ntawv thov:Kev tsim kho, kev sib txuas ntawm tsheb, kev siv hluav taws xob.
Lub luag haujlwm ntawm Catalyst:Cov tshuaj catalysts xws li MXC-T12 thiab MXC-BDMA txhim kho lub zog lo thiab kev kho kom zoo, uas yog qhov tseem ceeb rau kev sib txuas ruaj khov. Peb cov khoom txhawb nqa cov pa phem VOC tsawg thiab sib xws nrog ntau hom polyol thiab isocyanate systems.
