Cov khoom siv tseem ceeb ntawm cov vaj huam sib luag no tuaj yeem ua los ntawm ntau yam ua npuas ncauj, xws li polyurethane ua npuas ncauj, polystyrene hlaws board, lossis ua npuas ncauj iav. Ntawm cov no, polyurethane ua npuas ncauj feem ntau yog qhov kev xaiv nyiam vim nws cov khoom siv rwb thaiv tsev zoo heev thiab kev ua tau ntau yam. Kev nkag siab txog lub luag haujlwm ntawm polyurethane catalysts hauv kev tsim cov vaj huam sib luag sandwich yog qhov tseem ceeb rau cov tuam txhab tsim khoom uas tsom mus rau kev ua haujlwm zoo tshaj plaws thiab kev ua haujlwm zoo.

Polyurethane Ua Npuas Ncauj hauv Sandwich Panels

Ua npuas dej Polyurethane (PU) yog ib yam khoom tseem ceeb hauv kev tsim cov vaj huam sib luag sandwich. Nws muab kev rwb thaiv cua sov zoo heev, lub zog tsis hnyav, thiab kev ruaj khov ntawm cov qauv.Cov catalysts rau kev ua PU ua npuas ncauj, xws liMXC-T, MXC-C15, thiab lwm yam.Kev tsim cov ua npuas ncauj PU muaj kev sib xyaw ua ke ntawm polyols thiab isocyanates, uas ua los ntawm polyurethane catalysts. Cov catalysts no tseem ceeb heev rau kev tswj qhov nrawm ntawm kev sib xyaw, xyuas kom meej tias cov ua npuas ncauj zoo, thiab ua tiav cov yam ntxwv xav tau xws li qhov ceev, kev tawv, thiab kev tiv taus cua sov.

Lub Luag Haujlwm ntawm Polyurethane Catalysts

1. Kev Tswj Xyuas Cov Tshuaj: Cov tshuaj polyurethane catalysts tswj qhov ceev ntawm cov tshuaj tiv thaiv ntawm polyols thiab isocyanates. Los ntawm kev tswj cov tshuaj tiv thaiv no, cov chaw tsim khoom tuaj yeem tsim cov ua npuas ncauj nrog cov khoom zoo thiab cov yam ntxwv sib xws. Cov tshuaj catalysts pab ua kom muaj qhov sib npaug zoo ntawm cov ua npuas ncauj qhov rigidity thiab kev ywj pheej, kom ntseeg tau tias nws ua tau raws li cov kev cai tshwj xeeb rau cov ntawv thov sandwich panel.

2. Cov Khoom Ua Npuas Uas Zoo Dua: Kev siv cov tshuaj catalysts ua rau cov khoom siv ntawm PU ua npuas zoo dua. Cov tshuaj catalysts tuaj yeem hloov kho kom zoo dua cov yam ntxwv xws li lub zog compressive, kev nplaum rau cov ntaub ntawv ntsej muag, thiab kev ua kom sov. Qhov kev hloov kho no ua kom ntseeg tau tias cov npuas ua tau raws li cov qauv nruj uas xav tau rau cov ntaub ntawv tsim kho, muab kev ruaj khov thiab lub neej ntev rau cov vaj huam sib luag sandwich.

3. Kev Ua Haujlwm Zoo Hauv Kev Tsim Khoom: Cov tshuaj catalysts ua lub luag haujlwm tseem ceeb hauv kev ua kom cov txheej txheem tsim khoom zoo dua. Lawv ua rau lub sijhawm teb sai dua thiab txo qhov kev voj voog tsim khoom tag nrho, ua rau muaj kev ua haujlwm zoo dua thiab kev siv nyiaj tsawg. Qhov no tseem ceeb heev rau kev tsim khoom loj, qhov twg kev sib xws thiab kev ceev yog qhov tseem ceeb rau kev ua kom tau raws li qhov xav tau ntawm kev ua lag luam.

Hom Ua Npuas Ncauj Hauv Sandwich Panels

Thaum polyurethane ua npuas ncauj yog qhov kev xaiv nrov, cov vaj huam sib luag sandwich kuj tuaj yeem ua los ntawm kev siv lwm hom khoom siv ua npuas ncauj:

1. Polystyrene Bead Board (EPS): Expanded polystyrene bead board yog lwm cov khoom siv tseem ceeb rau cov sandwich panels. Nws muaj kev rwb thaiv tsev zoo thiab tsis hnyav. Txawm li cas los xij, nws tsis muab tib theem ntawm kev ua kom ruaj khov zoo li PU ua npuas ncauj.

2. Iav Ua Npuas Ncauj: Iav ua npuas ncauj yog ib yam khoom ruaj khov, tsis hnyav nrog cov yam ntxwv zoo heev ntawm kev rwb thaiv tsev kub thiab tiv taus dej noo thiab hluav taws. Nws feem ntau siv rau hauv cov ntawv thov uas tiv taus hluav taws thiab ua haujlwm ntev yog qhov tseem ceeb.
