Cov vaj huam sib luag polyurethane sandwich, feem ntau hu ua PU panels, yog cov khoom siv dav hauv kev tsim kho niaj hnub thiab kev lag luam vim lawv lub zog, kev ruaj khov thiab cov khoom rwb thaiv tsev thermal. Cov vaj huam sib luag no muaj peb txheej tseem ceeb: lub plawv polyurethane ua npuas ncauj uas rwb thaiv tsev zoo heev thiab muab tais rau ntawm ob daim hlau ruaj khov. Cov qauv sib xyaw no muaj kev ruaj khov zoo heev, rwb thaiv tsev thiab tiv taus huab cua, ua rau nws zoo tagnrho rau ntau yam chaw ib puag ncig. Cov tshuaj polyurethane catalysts hauv kev tsim cov vaj huam sib luag no ua kom muaj kev tsim khoom zoo thiab kev ua haujlwm ntawm cov plawv ua npuas ncauj.
Sandwich Panel yog dab tsi?
Lub vaj huam sib luag sandwich yog ib hom khoom siv ua vaj tse uas muab cov polyurethane ua npuas ncauj ua ke nrog cov txheej sab nraud, feem ntau yog hlau, los tsim cov khoom siv sib xyaw ua ke zoo. Lub plawv ua npuas ncauj, tsim los ntawm kev tshuaj lom neeg uas catalysts los ntawm polyurethane catalysts, muab kev rwb thaiv tsev zoo heev, pab tswj kom muaj qhov kub thiab txias sab hauv tsev thiab khoom siv ruaj khov. Cov txheej hlau sab nraud ntxiv kev ruaj khov, kev tiv thaiv, thiab kev ruaj khov. Kev sib xyaw ua ke no muab cov kev daws teeb meem sib dua tab sis ruaj khov rau phab ntsa, ru tsev, chaw cia khoom txias, thiab lwm yam kev siv uas qhov kev siv hluav taws xob zoo, qhov hnyav, thiab lub zog yog qhov tseem ceeb.
Lub Luag Haujlwm ntawm Polyurethane Catalysts hauv Sandwich Panels
Cov tshuaj polyurethane catalysts yog qhov tseem ceeb hauv kev tsim cov npuas dej ntawm cov vaj huam sib luag sandwich. Cov tshuaj catalysts zoo li MXC-T thiab MXC-C15, txhua tus muaj cov yam ntxwv sib txawv, ua kom cov tshuaj tiv thaiv ntawm polyols thiab isocyanates nrawm dua, ua rau muaj cov npuas dej nrog qhov ceev thiab cov qauv xav tau.
1.MXC-Tfeem ntau yog siv rau hauv kev tsim cov ua npuas ncauj mos uas ua los ntawm polyether, ua npuas ncauj pwm, ua npuas ncauj ib nrab tawv, thiab ua npuas ncauj tawv. Hauv cov vaj huam sib luag sandwich, MXC-T pab tswj cov qauv ua npuas ncauj, muab qhov nrawm sib npaug thiab cov qauv cell sib xws. Qhov sib xws no ua kom muaj kev rwb thaiv tsev thermal sib xws thiab txhim kho kev ruaj khov ntawm cov qauv vaj huam sib luag.
2.MXC-C15, ib qho amine catalyst, yog qhov tsim nyog rau kev pwm mos thiab semi-soft molding nrog rau kev siv ua npuas ncauj tawv. Hauv cov sandwich panels, nws pab txhawb kom ua tiav cov qauv ua npuas ncauj ruaj khov uas tswj nws cov khoom rwb thaiv tsev nyob rau hauv ntau qhov kub thiab txias. MXC-C15 txoj kev tswj hwm ntawm cov tshuaj tiv thaiv pab ua tiav qhov ntom ntom zoo tshaj plaws thiab qhov ntev ruaj khov, ua rau cov panels tiv taus kev hloov pauv thiab kev ntxhov siab ntawm ib puag ncig.
Cov ntawv thov ntawm PU Sandwich Panels
Cov vaj huam sib luag polyurethane sandwich siv dav hauv cov chaw cia khoom txias, cov tsev lag luam, cov tsev lag luam, thiab kev thauj mus los hauv lub tub yees, qhov twg kev tswj qhov kub thiab txias yog qhov tseem ceeb. Cov vaj huam sib luag polyurethane sandwich yog lub teeb yuag, sai dua rau kev teeb tsa, tsawg dua qhov hnyav ntawm cov qauv, thiab tiv taus huab cua hnyav rau lub neej ntev dua. Kev siv cov tshuaj polyurethane catalysts tshwj xeeb hauv cov txheej txheem tsim khoom txhim kho cov yam ntxwv no, ua rau cov vaj huam sib luag polyurethane sandwich yog qhov kev xaiv dav rau kev siv hluav taws xob zoo, cov kev daws teeb meem hauv tsev ruaj khov.
Hauv kev xaus lus, kev sib xyaw ua ke ntawm polyurethane ua npuas ncauj nrog cov tshuaj ua haujlwm siab xws li MXC-T thiab MXC-C15 tsim cov vaj huam sib luag sandwich uas muaj kev rwb thaiv tsev zoo heev, lub zog thiab kev tiv taus huab cua, txhawb nqa kev tsim kho kom ruaj khov thiab ua haujlwm tau zoo.
