Ib, ob qho kev sib piv ntawm qhov system
1. Thermal rwb thaiv tsev kev ua tau zoo:
Tib lub thickness ntawm EPS thiab XPS thermal rwb thaiv tsev kev ua tau zoo yog maj mam nce. EPS yog {{0}}.041 thiab XPS yog 0.030. Yog li ntawd, nyob rau hauv cov xwm txheej ntawm kev ua tau zoo tib yam thermal rwb thaiv tsev nyhuv, lub thickness ntawm XPS board yog nyias dua li ntawm EPS board, tab sis tus nqi ntawm ntshiab board XPS board yog kim dua li ntawm EPS board. Yog tias cov khoom siv tes ua thiab qhov siab ntawm lub tsev tau txiav txim siab tag nrho, tus nqi ib square meter ntawm XPS yog kim dua EPS.
Rau thermal rwb thaiv tsev, nws yog feem ntau pom cov thermal inertia Performance index D, thiab tus nqi D yog proportional rau lub tshav kub cia coefficient. Tab sis raws li tag nrho cov kev txhawj xeeb, lub tshav kub cia ntawm 200mm pob zeb yog qhov loj txaus, thiab cov txheej txheem rwb thaiv tsev sab nraud ntxiv kom ua tau raws li qhov xav tau ntawm lub zog txuag. Qhov no kuj yog vim li cas vim li cas lub teb chaws tus qauv yuav tsum muaj kev thermal conductivity thiab kub cia coefficient ntawm phab ntsa kom tau raws li qhov yuav tsum tau ua nyob rau tib lub sijhawm. Tam sim no EPS lossis XPS nyias plastering tshuab yog qhov txaus siab.
2. Lub zog:
Lub zog taw qhia ntawm no yuav tsum yog lub zog tensile. Qhov ntau ntom ntawm polystyrene board muaj kev sib raug zoo nrog lub zog tensile. Feem ntau, lub zog tensile ntawm EPS nrog qhov ceev ntawm 18Kg / m3 yog 110-120KPa, thiab qhov ntom ntom ntawm 20Kg / m3 yog li 140KPa. Qhov ceev ntawm XPS feem ntau yog los ntawm 25Kg txog 45Kg, thiab lub zog yog los ntawm 150KPa mus rau 700KPa lossis siab dua. (Lub ntsiab lus yog tias cov thermal conductivity yog li 0.03).
Tam sim no, lub zog ntawm XPS board yog 200KPa-250KPa. Lub zog zoo li no tsis tuaj yeem ua tiav los ntawm ntau lub rooj tsav xwm XPS hauv Suav teb. EPS board yog qis dua 100KPa. Nyob rau hauv cov ntaub ntawv ntawm ntau thiab ntau facade kho kom zoo nkauj thiab nquag typhoons nyob rau hauv cov ntug hiav txwv dej, lub zog yog heev heev. Nws yog ib qho tseem ceeb, tshwj xeeb tshaj yog rau qee cov vuas phab ntsa sab nrauv lossis cov tsev siab siab, uas ob lub vaj huam sib luag yuav tsum tau ntxiv dag zog los yog kho nrog fasteners. Daim duab ntawm cov pobzeb yuav tsum siab dua 400KPa, txawm tias XPS tsis tuaj yeem dais nws. Txoj kev daws teeb meem yog kho cov hlau mesh rau hauv paus los ntawm kev nthuav dav lub ntsia liaj qhov rooj, uas tuaj yeem cuam tshuam cov kev ntxhov siab tensile nyob rau hauv peb qhov chaw, yog li ntev li ntev raws li lub anchoring yog tsim nyog, cov duab tsis ua hauj lwm yuav tsum nyob rau hauv cov khoom sib xyaw. Qhov tawg-resistant mortar txheej ntawm cov hlau mesh tsis yog teeb meem loj.
Piv nrog rau EPS, lub zog ntawm XPS lub rooj tsavxwm yog siab dua, tab sis piv nrog EPS, vim qhov xwm txheej ntawm XPS pawg thawj coj saib, thaum thaj chaw pasting loj, qhov muaj peev xwm ntawm kev tawg ntawm phab ntsa sab nrauv yog siab, tshwj xeeb tshaj yog cov txheej txheej txheej. Flexibility yog qhov teeb meem ntawm cov khoom siv. Siv plastering ua piv txwv. Kev paub txog kev paub feem ntau yog siv cov plastering batch rau polystyrene board, thiab tom qab ntawd saib deb npaum li cas cov polystyrene board yog khoov yam tsis muaj kab nrib pleb ntawm plastering nto. Yog tias qhov hloov pauv tau zoo, nws tuaj yeem khoov ob peb zaug. yuav tsis tawg. Zoo ib yam li ductility Performance index nyob rau hauv cov ntaub ntawv waterproofing. Tab sis nyob rau hauv cov nqe lus ntawm cov khoom nws tus kheej, hloov tau EPS yog zoo dua XPS.
