Cov vaj huam sib luag sandwich yog ib qho tseem ceeb hauv kev tsim kho niaj hnub thiab cov txheej txheem rwb thaiv tsev. Lawv muaj peb txheej: cov khoom siv tseem ceeb, feem ntau yog ua los ntawm hlau, fiberglass lossis lwm yam khoom sib xyaw, muab tso rau ntawm ob txheej sab nraud. Cov vaj huam sib luag no muab kev rwb thaiv tsev zoo heev, lub teeb yuag thiab lub zog thiab siv dav hauv cov ntawv thov xws li lub tsev facades, ru tsev, cov tub yees thiab cov tsheb thauj mus los.
Cov Khoom Siv Raw rau Sandwich Panels
Cov Txheej Sab Nraud (Cov Ntawv Ntswg)
Cov txheej sab nraud feem ntau yog ua los ntawm cov hlau xws li hlau, txhuas, lossis fiberglass. Cov ntaub ntawv no muab kev ruaj khov ntawm cov qauv, tiv taus huab cua, thiab ruaj khov. Qee zaum, cov txheej sab nraud kuj tuaj yeem ua los ntawm cov polymers lossis cov ntaub ntawv sib xyaw, nyob ntawm seb qhov yuav tsum tau ua li cas.
Cov Khoom Siv Tseem Ceeb
Cov khoom siv tseem ceeb yog qhov tseem ceeb rau kev ua haujlwm rwb thaiv tsev ntawm lub vaj huam sib luag sandwich. Cov khoom siv feem ntau siv rau cov khoom siv tseem ceeb suav nrog:
Polyurethane (PU) ua npuas ncauj: Ua npuas dej polyurethane muaj cov khoom rwb thaiv tsev zoo heev thiab feem ntau siv rau hauv cov vaj huam sib luag sandwich. Nrog rau qhov sib piv ntawm lub zog thiab qhov hnyav siab, ua npuas dej polyurethane yog qhov kev xaiv nrov rau kev rwb thaiv tsev thiab kev txhawb nqa cov qauv.
Polyisocyanurate (PIR) ua npuas ncauj: PIR ua npuas ncauj yog lwm yam khoom siv ua haujlwm siab uas muaj kev tiv taus cua sov zoo dua li tus qauv PU ua npuas ncauj. PIR yog tsim los ntawm kev sib xyaw ntawm polyol thiab isocyanate nyob rau hauv qhov muaj cov tshuaj catalyst.
Cov ntaub plaub thiab polystyrene: Cov no kuj siv rau hauv qee qhov kev siv, tab sis feem ntau tsis tshua muaj zog thermal dua li polyurethane-based foams.
Cov Txheej Txheem Tsim Khoom ntawm Sandwich Panels
Kev tsim cov sandwich panels feem ntau muaj cov kauj ruam hauv qab no:
Kev Npaj Cov Khoom Siv Tseem Ceeb
Cov khoom siv tseem ceeb feem ntau yog ua npuas ncauj, ua los ntawm kev sib xyaw ntawm polyols, isocyanates, catalysts thiab additives. Tom qab ntawd ua npuas ncauj nthuav dav thiab tsim ua daim ntawv. Rau polyisocyanurate (PIR) ua npuas ncauj, trimerization yog qhov tseem ceeb kom ua tiav cov khoom rwb thaiv tsev xav tau. Qhov no yog qhov uas cov catalysts xws li MXC-TMA los ua si.
Lub Luag Haujlwm Catalyst: Qhov Tseem Ceeb ntawmMXC-TMA
MXC-TMA yog ib qho tshuaj catalyst tertiary amine uas yog ib qho tseem ceeb hauv kev tsim cov polyisocyanurate foams. Nws txhawb nqa qhov trimerization (polymerization) reaction ntawm polyisocyanurates, uas tsim cov foams khov kho rau cov sandwich panel cores.
Tsis zoo li cov catalysts uas muaj potassium,MXC-TMAmuab cov qauv nce siab sib npaug thiab tswj tau zoo dua thaum lub sijhawm ua npuas dej. Qhov no tso cai rau kev ntws zoo dua ntawm cov npuas dej, uas yog qhov tseem ceeb hauv cov ntawv thov xws li cov vaj huam sib luag thiab cov khoom siv rwb thaiv tsev tub yees uas xav tau cov qauv npuas dej sib xws thiab du. Kev tswj hwm kev teb sib xws pab tiv thaiv kev tsis sib xws xws li kev faib npuas dej tsis sib xws lossis qhov tsis zoo hauv cov khoom kawg.
Daim Ntawv Thov ntawm Lub Hauv Paus Nruab Nrab Sab Nraud
Thaum lub plawv ua npuas ncauj tau tsim thiab ruaj khov lawm, ces nws yuav raug muab tso rau ntawm ob txheej sab nraud ntawm cov hlau lossis cov khoom sib xyaw. Cov txheej no raug sib txuas rau lub plawv ua npuas ncauj, feem ntau yog siv kev sib xyaw ua ke ntawm cua sov thiab kev nias, uas ua kom muaj kev sib txuas zoo thiab kaw cov khoom tseem ceeb kom ruaj khov.
Kev Kho Kom Kho thiab Kev Kho Zaum Kawg
Tom qab ua tiav lub vaj huam sib luag sandwich, lub ua npuas dej yuav raug kho kom qhuav thiab ua kom cov tshuaj lom neeg uas tseem tshuav nyob hauv lub ua npuas dej tiav. MXC-TMA ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov kho kom qhuav tom qab hauv cov ntawv thov ua npuas dej uas yoog tau, kom ntseeg tau tias lub ua npuas dej ua kom nws tawv thiab ua haujlwm tau zoo tshaj plaws.
Txiav thiab Ua Duab
Thaum kawg, cov sandwich panels raug txiav mus rau qhov loj me uas xav tau rau lawv daim ntawv thov tshwj xeeb, txawm tias rau kev tsim kho facades, phab ntsa cia khoom txias, lossis lwm yam kev siv. Cov panels ces npaj txhij rau kev teeb tsa hauv ntau yam kev tsim kho lossis kev lag luam.
Vim li cas MXC-TMA tseem ceeb rau kev tsim cov vaj huam sib luag sandwich
MXC-TMA lub peev xwm los tswj cov tshuaj polyisocyanurate ua rau nws tseem ceeb heev rau kev tsim cov sandwich panels zoo. Los ntawm kev txhawb nqa cov txheej txheem trimerization thiab txhim kho kev ua haujlwm, MXC-TMA ua kom ntseeg tau tias lub plawv ua npuas ncauj kawg muaj cov qauv sib xws, cov khoom rwb thaiv tsev zoo dua, thiab lub zog zoo heev. Qhov no ua rau cov sandwich panels ruaj khov thiab ua haujlwm tau zoo uas haum rau ntau yam kev siv.
Xaus lus
Kev tsim cov sandwich panels muaj kev sib xyaw ua ke ntawm cov khoom siv raw thiab cov thev naus laus zis tsim khoom meej. Lub plawv ua npuas polyisocyanurate uas cov khoom xws li MXC-TMA ua rau muaj kev rwb thaiv tsev thiab lub zog tsim kho rau cov ntaub ntawv tsim kho no. Nrog nws lub peev xwm tshwj xeeb los tswj kev ua haujlwm thiab txhim kho kev ntws, MXC-TMA yog cov khoom tseem ceeb los xyuas kom meej tias cov sandwich panels siv hauv ntau yam lag luam muaj kev ua tau zoo thiab zoo.
