A33 yog 33% triethylenediamine tov uas yog siv los ua gel catalyst rau polyurethane ua npuas ncauj. Nws yog dav siv nyob rau hauv mos, semi-rigid, thiab rigid polyurethane foams, elastomers, coatings, thiab lwm yam. Nyob rau hauv industrial siv, triethylenediamine feem ntau yog yaj nyob rau hauv me me molecular diols thiab configured rau hauv ib tug cawv tov nrog ib tug loj feem ntawm 33% (los yog lwm yam concentrations). Feem ntau siv diols suav nrog dipropylene glycol, propylene glycol, diethylene glycol (diethylene glycol), ethylene glycol, thiab lwm yam.
Raws li ib tug catalyst, triethylenediamine tswj cov tshuaj tiv thaiv tus nqi los ntawm kev txhawb cov tshuaj tiv thaiv ntawm isocyanate nrog dej (foaming cov tshuaj tiv thaiv) thiab cov tshuaj tiv thaiv ntawm hydroxyl nrog isocyanate (gel cov tshuaj tiv thaiv), yog li ua kom muaj kev ruaj ntseg thiab kev ua tau zoo ntawm polyurethane ua npuas ncauj. Nws cov txheej txheem tshuaj lom neeg ntawm kev ua yog tias nws tuaj yeem ua kom cov tshuaj tiv thaiv no, yog li tswj kev tsim thiab kho cov txheej txheem ua npuas ncauj.
Triethylenediamine feem ntau yog siv los ua cov catalyst hauv polyurethane foaming. Nws lub luag haujlwm tseem ceeb tshaj plaws yog tswj xyuas qhov nrawm ntawm cov tshuaj tiv thaiv foaming thiab cov tshuaj tiv thaiv gel kom lawv nyob hauv qhov sib npaug zoo. Nws yog ib qho tseem ceeb tshaj plaws tertiary amine catalysts hauv cov khoom ua npuas ncauj, nrog 60% ntawm nws cov kev ua tau zoo siv los txhawb cov tshuaj tiv thaiv ntawm isocyanate thiab dej, piv txwv li, cov tshuaj tiv thaiv foaming, thiab 40% siv los txhawb cov tshuaj tiv thaiv ntawm hydroxyl thiab isocyanate, ie, cov tshuaj tiv thaiv gelling.
