Peb cov khoom siv sandwich panel
Peb muab ntau yam catalysts tsim los ua kom tau raws li ntau yam kev xav tau ntawm kev tsim khoom:
- Lub npe ntawm cov khoomMXC-37yog 2-(2-(dimethylamino)ethoxy)ethanol, luv ua DMAEE, nrog tus lej CAS ntawm 1704-62-7. Nws yog ib qho tshuaj catalyst uas tsis tso tawm, tsw qab tsawg uas siv rau hauv kev tsim cov polyurethane ua npuas ncauj. Vim nws cov dej num ua npuas ncauj siab, nws yog qhov tsim nyog rau cov qauv uas muaj cov dej ntau, feem ntau rau cov dej tsawg, cov dej-tshuab cellular tsuag polyurethane ua npuas ncauj (SPF). Kev koom ua ke DMAEE rau hauv cov polymer txo cov ntxhiab tsw amine uas pom muaj nyob rau hauv cov npuas ncauj. Nws tuaj yeem siv ib leeg ua tus catalyst tseem ceeb lossis ua tus co-catalyst los txo qhov kev siv BDMAEE ua npuas ncauj catalysts. Siv rau hauv ester-based stabilizer soft foams, microcellular foams, elastomers, RIM thiab RRIM, thiab cov ntawv thov ntim khoom ua npuas ncauj nruj.
- MXC-C15sawv cev rau 3,3′-Iminobis (N,n-dimethylpropylamine), CAS NO. 6711-48-4, yog cov tshuaj amine uas tsis muaj emitting, tsw qab tsawg uas yog me ntsis xaiv rau urea (isocyanate-water) cov tshuaj tiv thaiv.
