Cov ua npuas dej polyurethane ua lub luag haujlwm tseem ceeb hauv ntau yam lag luam, txij li rooj tog thiab ntaub pua chaw pw mus rau tsheb thiab kev siv rwb thaiv tsev. Kev tsim cov ua npuas dej polyurethane zoo nyob ntawm kev tsim cov qauv kom raug thiab kev xaiv cov catalyst kom raug. Ntawm lawv, cov hlau catalysts yog cov khoom xyaw tseem ceeb uas tsav cov tshuaj tiv thaiv ntawm polyols thiab isocyanates kom ntseeg tau tias muaj kev ua haujlwm zoo tshaj plaws thiab ua haujlwm tau zoo.
Dab tsi yogcov tshuaj catalysts hlau?
Cov tshuaj catalysts hlau yog cov tshuaj uas ua kom cov tshuaj tiv thaiv ntawm polyols thiab isocyanates sai dua hauv kev tsim cov polyurethane ua npuas ncauj. Tsis zoo li cov tshuaj catalysts amine, uas feem ntau cuam tshuam rau cov tshuaj tiv thaiv foaming, cov tshuaj catalysts hlau feem ntau txhawb nqa cov tshuaj tiv thaiv gelation, ua rau muaj cov qauv ua npuas ncauj ruaj khov thiab ruaj khov.
Daim Ntawv Thov Cov Hlau Catalysts hauv Polyurethane Ua Npuas Ncauj
Cov catalysts hlau siv dav hauv ntau hom polyurethane ua npuas ncauj, suav nrog:
1. Ua npuas polyurethane uas yoog tau:
- Siv rau hauv rooj tog, txaj pw thiab lub rooj zaum hauv tsheb.
- Muab kev ruaj khov thiab kev ua haujlwm ntev.
- Txhim kho qhov xis nyob thiab elasticity ntawm lub ua npuas ncauj.
2. Ua npuas ncauj polyurethane ruaj khov:
- Feem ntau pom muaj nyob rau hauv cov ntaub ntawv rwb thaiv tsev hauv cov tsev, cov tub yees thiab cov tub yees khov.
- Txhim kho kev tiv taus cua sov thiab kev siv hluav taws xob zoo.
- Pab txhim kho qhov hluav taws kub thiab lub zog kho tshuab.
3. Cov ua npuas dej me me thiab cov ua npuas dej ywj pheej:
- Siv rau hauv khau, gaskets, thiab qhov chaw tsheb.
- Muab kev tiv thaiv zoo heev thiab kev ywj pheej.
- Xyuas kom muaj kev ua tau zoo mus sij hawm ntev hauv cov chaw muaj kev ntxhov siab heev.
