     sawb (2) DSC04937-2 EPS BOARD MAKING TSHUAB tshuab foaming Cov duab 202205181112201 Cov duab 202205181112202 Cov duab 202205181112203Ib txoj kev tshawb fawb Canadian tshawb xyuas qhov kev ua haujlwm ntev ntawm kev nthuav dav polystyrene (EPS) hauv kev sib cuag nrog hauv av tau thov EPS cov tuam txhab hauv North America thiab Canada kom lees tias cov rwb thaiv tsev tsim nyog rau kev siv hauv av, zoo ib yam li kev ua haujlwm ntawm extruded polystyrene (XPS) ).
Tom qab ntawd, raws li cov pov thawj ntawm shingle tsis ua hauj lwm, kev lag luam-kev txhawb nqa kev tshawb fawb tau pom tias kev ua tau zoo ntawm XPS hauv kev siv tiag tiag hauv ntiaj teb tsis sib xws hauv kev sim ntsuas, ua EPS yog cov khoom zoo. Thaum lub XPS kev lag luam tau tsis lees paub cov txiaj ntsig no nrog lawv tus kheej kev tshawb fawb, nws yog qhov nthuav tias XPS cov tuam txhab tau hloov lawv lub hom phiaj los ntawm qhov tsis tshua muaj hygroscopicity pom nyob rau hauv chav kuaj immersion thiab huab cua nyob rau hauv cov huab cua noo mus rau cov khoom ya raws ntawm XPS.
Feem ntau XPS tsis ua haujlwm yog vim qhov nyuaj ntawm kev txhim kho shingle thiab siv cov ntaub ntawv ua ke nrog cov khoom tsis zoo waterproofing membranes. Muaj pov thawj tias XPS yog qhov zoo dua thaum tsis txhob txhob txwm tso dej nyob ib puag ncig thiab nyob rau hauv lub rwb thaiv tsev, muab cov dej noo ntau dua thaum tiv thaiv hauv av.
EPS perimeter rwb thaiv tsev yog ib txwm ntsia nrog cov khoom siv rov qab los ntawm cov khoom siv, polyethylene rau kev tiv thaiv ua npuas ncauj, thiab cov kav dej hauv qab rwb thaiv tsev. Txawm li cas los xij, XPS tsuas yog ntsia tau siv polyethylene daim nyias nyias.
Qhov sib xyaw ntawm EPS thiab XPS rwb thaiv tsev tau hloov pauv raws sijhawm, piv txwv li, cov khoom siv tshuab ntawm ob qho tib si tau hloov pauv. Hauv North America thiab Canada, XPS yog tam sim no tsim tsis muaj ozone depleting tshuab, tab sis qhov no tsis yog lwm qhov. Qee cov khoom XPS tuaj rau New Zealand zoo li tau ua los ntawm kev txiav cov khoom xoob es tsis yog extruding los ntawm cov tawv tawv. Lub cuticle ntawm daim ntawv XPS slows down aging thiab yog ib qho tseem ceeb contributor rau ya raws.
BRANZ tau kuaj XPS cov khoom siv thermal conductivity ntawm 0.036 W / mK. Nyob rau hauv sib piv, cov conductivity ntawm carbon-filled polystyrene ua npuas ncauj yog ho qis dua tus nqi no. Feem ntau ntawm cov styrofoam uas tsim nyob rau hauv New Zealand muaj cov khoom siv rov ua dua tshiab thiab qee zaum tuaj yeem muaj cov qauv ntxeem tau ntau dua.
Txhawm rau kom cov av noo mus rau hauv av, qhov zoo tshaj plaws ua npuas dej yuav tsum tsis txhob npog tag nrho los ntawm kev thaiv dej. Nyob rau lub caij ntuj no, txhua qhov dej noo ntawm lub hauv paus ntawm phab ntsa yuav raug yuam kom tawm mus rau hauv ib puag ncig rwb thaiv tsev, yog li nws yog qhov zoo tshaj plaws los siv cov khoom siv hluav taws xob rau sab nraum lub rwb thaiv tsev. Yog tias qhov no tsis tuaj yeem ua tau, cov npuas dej yuav tsum nkag mus rau hauv av, tsuas yog ib qho kev tiv thaiv tsis zoo rau saum av.
Raws li txoj cai dav dav, cov ntsiab lus dej ntawm lub hauv paus yuav tsum tsis txhob siab dhau, yog li qhov kev pheej hmoo tseem ceeb hauv kev rov qab ua dua los ntawm cov nyhuv capillary thaum dej nkag mus rau ntawm cov rwb thaiv tsev thiab cov pob zeb. Qhov no tuaj yeem zam tau los ntawm kev siv lub capillary so (xws li butyl daim kab xev) nyob rau hauv qab ntug ntawm lub insulator.
