Hauv kev lag luam polyurethane thoob ntiaj teb,cov catalysts ua lub luag haujlwm tseem ceebhauv kev ua kom cov tshuaj tiv thaiv sai dua, ua kom cov khoom ua npuas zoo dua, thiab txhim kho kev ua haujlwm ntau lawm. Raws li polyurethane txuas ntxiv nthuav dav thoob plaws hauv kev lag luam xws li rwb thaiv tsev, tsheb, rooj tog, khau, thiab kev tsim kho, qhov kev thov rau kev ua tau zoocov tshuaj polyurethane catalyststau nce ntxiv ntau heev. Kev nkag siab txogkev loj hlob thiab kev vam meej ntawm thev naus laus zishauv qhov kev lag luam no yog qhov tseem ceeb rau cov tuam txhab tsim khoom uas tab tom nrhiav kom nyob ua ntej hauv kev ua lag luam sib tw.
1. Cov tshuaj polyurethane catalysts:Lub Pob Zeb Tseem Ceeb ntawm Kev Tsim Ua Npuas Ncauj
Polyurethane yog tsim los ntawm kev sib xyaw ntawm polyols thiab isocyanates, ib qho txheej txheem uas nyob ntawm cov catalysts. Cov catalysts no—feem ntau yog amine-based thiab hlau-based—tswj covkev ua npuas (tshuab) thiab kev ua kom gelling (kho) cov tshuaj tiv thaiv, xyuas kom meej tias cov khoom zoo sib xws, lub zog kho tshuab, thiab cov qauv ua npuas ncauj xav tau.
Muaj ntau pawg ntawm cov catalysts siv hauv polyurethane systems:
- Cov amines theem peb:Txhawb kom muaj kev sib xyaw thiab / lossis gelling.
- Cov tshuaj catalysts uas ua los ntawm hlau(xws li tin, potassium, lossis bismuth compounds): Ua kom cov txheej txheem kho sai dua thiab txhim kho cov khoom kawg.
- Cov tshuaj catalysts uas tsis muaj pa phem thiab cov tshuaj tiv thaiv kab mobTsim los teb rau cov cai ib puag ncig.
2. Cov Qauv Kev Loj Hlob ntawm Kev Lag Luam
a. Kev Ua Raws Cai Ib puag ncig thiab Cov Qauv Uas Muaj Pa Phem Tsawg
Nrog rau kev ua kom nruj dua ntawm cov cai ib puag ncig xws liREACH hauv Tebchaws Europe, TSCA hauv Tebchaws Meskas, thiab cov kev pib txo qis VOC thoob ntiaj teb, cov chaw tsim khoom polyurethane catalyst tab tom hloov mus raucov pa phem tsawg, tsis muaj tshuaj lom, thiab cov tshuaj catalyst reactive.Cov tshuaj catalysts uas ua los ntawm tin lossis cov tshuaj amine uas muaj ntxhiab tsw qab ntau zuj zus raug hloov los ntawm:
- Cov tshuaj catalysts amine uas muaj zoguas dhau los ua chemically bound hauv polyurethane matrix.
- Lwm txoj hauv kev xaiv qis-VOCuas txo cov pa phem thaum lub sijhawm tsim khoom thiab siv cov khoom.
- Cov tshuaj catalysts uas tsis yog hlau hnyav(piv txwv li, bismuth lossis zinc-based) los hloov dibutyltin dilaurate (DBTDL).
Peb cov khoom lag luam daws qhov teeb meem no nrog cov kev daws teeb meem zoo liMXC-B20,MXC-R40,thiabMXC-T12,uas muab cov tshuaj tiv thaiv zoo heev thaum ua tau raws li cov qauv ib puag ncig thiab kev nyab xeeb thoob ntiaj teb.
b. Kev Sib Xws ntawm HFO Blowing Agent
Nrog rau kev txo qis ntawm cov neeg sawv cev ua pa uas muaj GWP siab, xws li HFC-245fa, kev lag luam tau siv dav davCov txheej txheem raws li HFO(piv txwv li, HFO-1233zd). Cov kab ke no xav tau cov catalysts zoo kom tswj tau qhov sib npaug ntawm cov tshuaj tiv thaiv kinetics thiab kev ua haujlwm ua npuas ncauj. Peb cov catalysts sib xws nrog HFO, xws liMXC-MB20thiabMXC-70, tau tsim tshwj xeeb los muab cov qauv du thiab zoo heev rau kev kho qhov chaw hauv HFO systems, feem ntau siv rau hauvtshuaj tsuag ua npuas ncauj, cov ntoo tawv,thiabkev rwb thaiv tsev ntawm cov khoom siv.
c. Cov Ntawv Thov Ua Haujlwm Zoo
Cov kev siv polyurethane niaj hnub no xav tau ntau dua li kev ua npuas ncauj yooj yim. Cov rooj zaum hauv tsheb, cov hauv qab khau, cov npuas ncauj tawv nqaij, thiab cov khoom siv rwb thaiv tsev uas txuag hluav taws xob txhua yam xav tau cov tshuaj catalysts uas muab:
- Kev ua haujlwm qeeb rau kev sau pwm zoo dua
