Lub Luag Haujlwm ntawmCov tshuaj Polyurethane Catalystshauv Kev Tsim Ua Npuas Ncauj
Cov tshuaj polyurethane catalysts yog cov khoom tseem ceeb hauv kev ua cov npuas kaw thiab cov npuas qhib. Cov tshuaj catalysts no yog lub luag haujlwm rau kev tswj cov tshuaj tiv thaiv ntawm polyols thiab isocyanates thaum lub sijhawm tsim cov npuas. Yog tsis muaj tshuaj catalyst, cov tshuaj tiv thaiv no qeeb thiab tsis ua haujlwm zoo, ua rau cov npuas tsis zoo. Kev xaiv cov tshuaj catalyst cuam tshuam ncaj qha rau cov khoom ua npuas xws li qhov ceev, cov qauv ntawm cov npuas, lub sijhawm nce, thiab qhov ceev kho.
Nov yog li cas polyurethane catalysts ua haujlwm thiab lawv cuam tshuam li cas rau kev tsim ua npuas ncauj:
1. Kev Sib Npaug ntawm Cov Tshuaj Tiv Thaiv ntawm Polyols thiab Isocyanates
Hauv kev tsim cov polyurethane ua npuas ncauj, cov catalysts pab tswj ob qho kev cuam tshuam tseem ceeb: qhovkev ua kom gellingthiab lubkev ua pa tshuabQhov kev ua gelling yog hais txog kev tsim cov qauv polymer, thaum qhov kev ua kom tshuab ua rau cov pa roj uas nthuav cov ua npuas ncauj.
Cov tshuaj polyurethane catalysts tuaj yeem faib ua pawg:cov tshuaj amine catalyststhiabcov tshuaj catalysts hlau, ob qho tib si ua lub luag haujlwm sib txawv:
Cov tshuaj amine catalystsCov catalysts no, xws liMXC-37 (DMAEE)thiabMXC-A1 (BDMAEE), txhawb nqakev ua pa tshuab, pab tswj cov qauv ntawm lub cell ua npuas ncauj. Qhov no tseem ceeb heev rau kev tsim cov ua npuas ncauj qhib, qhov twg cov catalyst xav tau los tsim cov qauv uas muaj huab cua thiab yoog tau.
Cov Khoom Siv Hlau: Dibutyltin dilaurate (MXC-T12)piv txwv li, feem ntau txhawb nqa qhovkev ua kom gelling, ua rau muaj cov qauv khov kho thiab ruaj khov. Hauv kev tsim cov ua npuas ncauj kaw, cov tshuaj catalysts no tseem ceeb heev rau kev ua kom cov ua npuas ncauj ruaj khov.
2. Kev Txhim Kho Qhov Ceev thiab Lub Zog Ua Npuas Ncauj
Lub kaw lus catalyst ua lub luag haujlwm tseem ceeb hauv kev txhais cov txheej txheemqhov ceevthiablub zogntawm cov ua npuas ncauj. Rau cov ua npuas ncauj kaw-cell, cov catalyst zoo ua kom ntseeg tau tias cov ua npuas ncauj muaj lub zog thiab kev nruj kom tiv taus kev ntxhov siab, thaum rau cov ua npuas ncauj qhib-cell, cov catalyst pab tswj kom cov qauv mos dua, yoog tau dua. Cov catalysts xws liMXC-15 (potassium octanoate)lawv muaj txiaj ntsig zoo hauv kev ua kom cov npuas dej ntom ntom thiab ua kom muaj kev faib tawm ntawm cov cell sib npaug, uas yog qhov tseem ceeb rau cov ntaub ntawv rwb thaiv tsev ua haujlwm siab.
3. Tswj Lub Sijhawm Sawv thiab Qhov Ceev Kho
Hauv kev siv tshuaj tsuag polyurethane ua npuas ncauj (SPF), kev tswj lub sijhawm nce thiab qhov ceev ntawm kev kho yog qhov tseem ceeb kom ntseeg tau tias daim ntawv thov du thiab cov khoom kawg ruaj khov. Cov tshuaj catalysts xws liMXC-T(ib qho tin catalyst zoo ib yam li T) lossisMXC-R70(2-(2-dimethylaminoethoxy)ethanol)tau tsim los kom muaj lub sijhawm kho sai thiab cov tshuaj tiv thaiv sib npaug, ua rau muaj kev siv ua npuas ncauj zoo hauv qhov chaw. Kev kho sai dua txhais tau tias lub sijhawm luv dua tsis muaj cov kua nplaum thiab muaj peev xwm thov ntau txheej sai, uas yog qhov tseem ceeb hauv kev siv SPF loj.
4. Txo Cov Pa Tawm thiab Cov Ntxhiab
Hauv kev tsim ua npuas ncauj niaj hnub no, kev xav txog ib puag ncig yog qhov tseem ceeb heev, thiab kev txo cov pa phem thiab cov ntxhiab tsw los ntawm cov tshuaj catalysts tau dhau los ua qhov tseem ceeb. Cov tshuaj catalysts uas muaj ntxhiab tsw tsawg, cov pa phem tsawg xws liMXC-R40thiabMXC-TMAtau tsim los ua kom tau raws li cov cai ib puag ncig nruj thaum tswj hwm kev ua haujlwm catalytic siab. Cov catalysts no tseem ceeb heev rau kev siv rwb thaiv tsev sab hauv, qhov twg muaj cov ntxhiab tsw muaj zog lossis cov pa phem tuaj yeem ua teeb meem.
