Thaum nws los txog rau kev tsim vaj huam sib luag sandwich, kev xaiv cov khoom siv tseem ceeb yog qhov tseem ceeb rau kev ua kom ntseeg tau tias muaj kev ua tau zoo raws li qhov xav tau ntawm kev rwb thaiv cua sov, rwb thaiv suab, tiv thaiv hluav taws, thiab lub zog. Cov khoom siv tseem ceeb sib txawv hauv kev sib xyaw, txhua tus muab cov txiaj ntsig tshwj xeeb nyob ntawm qhov xav tau tshwj xeeb ntawm daim ntawv thov.
Cov Vaj Huam Sib Luag Ua Npuas Ncauj
Cov pob ua npuas ncauj, tshwj xeeb tshaj yogpolyurethane(PUR) thiab polyisocyanurate (PIR), yog cov kev xaiv nrov tshaj plaws rau cov sandwich panels.PolyurethaneCov vaj huam sib luag tseem ceeb muaj cov khoom siv rwb thaiv cua sov zoo heev, ua rau lawv zoo tagnrho rau cov ntawv thov uas kev siv hluav taws xob zoo yog qhov tseem ceeb tshaj plaws. Txawm li cas los xij, lawv qhov kev tiv thaiv hluav taws kub yog qee yam txwv piv rau lwm cov ntaub ntawv. Txhawm rau daws qhov no, PIR panels tau tsim los ua qhov hloov kho dua ntawm PUR, muab kev tiv thaiv hluav taws kub zoo dua, kev rwb thaiv cua sov, thiab kev ruaj khov. PIR panels zoo rau ob qho tib si kev lag luam thiab kev siv hauv tsev uas xav tau kev nyab xeeb hluav taws zoo dua.
Cov khoom siv ua npuas ncauj phenolic (PF) tseem ceeb, txawm tias kim dua PUR thiab PIR, muab kev tiv thaiv hluav taws zoo dua thiab kev rwb thaiv cua sov siab dua me ntsis. Cov vaj huam sib luag no feem ntau raug xaiv thaum kev tiv thaiv hluav taws yog qhov tseem ceeb, txawm hais tias tus nqi siab dua yuav yog qhov yuav tsum tau xav txog hauv cov haujlwm uas xav tau nyiaj txiag.
Cov vaj huam sib luag ua los ntawm polystyrene ua npuas ncauj, tshwj xeeb tshaj yog cov uas nthuav dav (EPS) thiab cov polystyrene uas raug rho tawm (XPS), muab lwm txoj hauv kev pheej yig. Cov vaj huam sib luag EPS siv dav hauv cov haujlwm uas pheej yig tab sis muaj kev tiv taus kub thiab hluav taws tsawg dua li PUR lossis PIR. Ntawm qhov tod tes, XPS muaj qhov ceev dua, muab kev tiv taus kub, dej noo, thiab pa dej zoo dua li EPS, ua rau nws yog qhov kev xaiv zoo rau cov chaw uas muaj dej noo.
Cov Vaj Huam Sib Luag Tsis Yog Ua Npuas Ncauj
Rau cov ntawv thov uas qhov kev tiv thaiv hluav taws thiab kev rwb thaiv suab nrov tseem ceeb dua, cov vaj huam sib luag mineral wool tseem ceeb tshaj plaws. Mineral wool yog cov khoom siv uas tsis kub hnyiab, muab kev tiv thaiv hluav taws zoo heev thiab muaj peev xwm tiv thaiv suab nrov zoo dua. Txawm li cas los xij, nws hnyav dua PIR thiab muaj kev rwb thaiv cua sov qis dua, ua rau nws tsim nyog dua rau cov haujlwm uas qhov kev tiv thaiv hluav taws tseem ceeb dua li kev ua haujlwm thermal.
Cov Vaj Huam Sib Luag Honeycomb
Cov qauv honeycomb, feem ntau ua los ntawm txhuas, polypropylene, lossis cardboard, paub txog lawv qhov sib piv siab zog rau qhov hnyav, ua rau lawv zoo tagnrho rau cov ntawv thov uas lub zog kho tshuab tseem ceeb. Txawm li cas los xij, lawv tsis muab tib theem ntawm kev rwb thaiv tsev thermal li cov vaj huam sib luag ua npuas ncauj, ua rau lawv tsis haum rau cov haujlwm uas kev rwb thaiv tsev kub yog qhov tseem ceeb.
Hauv kev xaus, qhov kev xaiv cov khoom siv tseem ceeb nyob ntawm qhov xav tau tshwj xeeb ntawm qhov project. PUR thiab PIR cores zoo heev rau kev rwb thaiv tsev thermal, thaum cov ntaub plaub mineral wool zoo heev hauv kev tiv thaiv hluav taws thiab rwb thaiv tsev suab. Rau cov ntawv thov uas tsom mus rau lub zog, cov honeycomb cores tej zaum yuav tsim nyog dua, txawm hais tias lawv tsis muaj kev ua haujlwm thermal. Txhua cov khoom siv tseem ceeb muaj cov txiaj ntsig sib txawv, thiab qhov kev xaiv zoo tshaj plaws thaum kawg nyob ntawm qhov sib npaug ntawm kev ua tau zoo xws li kev rwb thaiv tsev, kev nyab xeeb hluav taws, thiab kev ua haujlwm ruaj khov.
