Polyurethane tau ntev los lees paub tias yog ib yam khoom siv uas hloov tau yooj yim heev, thiab nws qhov kev ua tau ntau yam ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv hauv kev lag luam, tshwj xeeb tshaj yog hauv Coatings, Adhesives, Sealants, thiab Elastomers (CASE). Cov ntawv thov no xav tau cov catalysts ua tau zoo uas tuaj yeem ua kom zoo dua qhov kev ua haujlwm ntawm cov tshuaj tiv thaiv thaum ua kom cov khoom ua tau zoo dua. Rau cov tuam txhab tsim cov polyurethane systems, kev xaiv cov catalyst zoo yog qhov tseem ceeb rau kev sib npaug ntawm kev ua haujlwm zoo, kev nyab xeeb, thiab lub neej ntev ntawm cov khoom.
Peb cov tshuaj polyurethane catalysts muaj kev ua haujlwm siab muab cov kev daws teeb meem uas tsim los rau cov kev xav tau tshwj xeeb ntawm CASE daim ntawv thov, pab cov neeg tsim cov khoom ua tiav cov khoom zoo heev xws li kev nplaum, kev ywj pheej, thiab kev tiv taus cov yam ntxwv ib puag ncig. Ntawm peb cov tshuaj catalysts ua ntej,MXC-R70(2-(2-dimethylaminoethoxy)ethanol, CAS 1704-62-7) sawv tawm rau nws cov reactivity thiab haum rau ntau yam ua npuas ncauj thiab cov khoom elastomeric.
Lub Luag Haujlwm ntawmCov tshuaj catalystshauv CASE Daim Ntawv Thov
Cov tshuaj catalysts ua lub hauv paus tseem ceeb ntawm cov tshuaj lom neeg uas hloov cov kua polyurethane ua cov khoom ruaj khov thiab ua tau zoo. Lawv ua kom cov tshuaj ua npuas (tshuab) thiab kho (gelling) sai dua, ua kom cov khoom kawg muaj cov khoom siv kho tshuab thiab lub cev xav tau.
Hauv CASE daim ntawv thov, qhov no txhais tau tias txhim kho cov yam tseem ceeb xws li:
- Kev nplaum: Xyuas kom muaj kev sib txuas zoo ntawm cov nto, uas yog qhov tseem ceeb hauv cov nplaum thiab cov sealant.
- Kev Yooj Yim thiab Kev Ruaj Khov: Ua kom cov roj hmab elastomer ruaj khov thiab tsis yooj yim tawg thaum siv.
- Qhov Chaw Tiav: Txhim kho qhov sib xws thiab cov khoom zoo nkauj ntawm cov txheej txheem.
- Kev Ua Haujlwm Zoo: Pab kom cov voj voog tsim khoom sai dua nrog lub sijhawm kho kom zoo.
Cov Ntawv Thov Tseem Ceeb ntawmMXC-R70hauv CASE
MXC-R70, ib qho tshuaj catalyst uas ua rau cov amine tsis yaj, ua lub luag haujlwm tseem ceeb hauv kev tsim ntau yam khoom polyurethane, suav nrog cov microcellular foams thiab elastomers. Nws cov reactivity siab ua rau nws tsim nyog rau cov qauv vinyl ua npuas ncauj xws li lub dashboards thiab headrests hauv tsheb, qhov twg xav tau kev ua kom raug thiab ruaj khov. Los ntawm kev txhawb nqa kev kho sai yam tsis muaj kev cuam tshuam rau qhov yooj ywm thiab kev nplij siab ntawm cov npuas ncauj, MXC-R70 yog qhov tseem ceeb rau cov ntawv thov uas xav tau kev ua haujlwm siab thiab kev nplij siab.
Cov yam ntxwv tseem ceeb ntawm MXC-R70:
- Kev ua haujlwm siab: Tso cai rau lub sijhawm teb tau zoo thiab sai hauv ob qho tib si kev ua npuas dej thiab kev kho.
- Cov ntawv thov ntau yam: Haum rau ntau yam kev siv, los ntawm cov microcellular foams mus rau elastomers, muab cov khoom zoo heev hauv txhua daim ntawv thov.
- Tshuaj lom tsawgTxo qhov kev vam khom rau cov tshuaj lom neeg xws li dibutyltin, ua kom cov txheej txheem tsim khoom muaj kev nyab xeeb dua rau cov neeg ua haujlwm thiab cov chaw tsim khoom.
Txo Kev Raug Cov Tshuaj Lom Zem
Ib qho kev txhawj xeeb uas loj hlob tuaj hauv kev lag luam polyurethane yog kev txo qis kev raug rau cov tshuaj lom xws li dibutyltin. Peb cov tshuaj catalysts tshiab, suav nrog MXC-R70, muab lwm txoj hauv kev nyab xeeb dua los ntawm kev txo qis lossis tshem tawm qhov xav tau cov tshuaj lom no. Qhov no tsis yog tsuas yog txhim kho kev nyab xeeb hauv chaw ua haujlwm xwb tab sis kuj ua raws li cov cai ib puag ncig uas hloov pauv thiab cov neeg siv khoom xav tau cov khoom huv dua thiab ntsuab dua.
