Kev sib piv ntawm EPS thiab XPS System Performance
1. Thermal rwb thaiv tsev kev ua tau zoo:
Cov khoom insulating ntawm EPS thiab XPS nrog tib lub thickness yog maj mam txhim kho. EPS yog {{0}}.041 thiab XPS yog 0.030. Yog li, XPS pawg thawj coj saib yog nyias dua li EPS pawg thawj coj saib thaum ua tiav cov txiaj ntsig zoo ib yam, tab sis XPS pawg thawj coj saib kim dua EPS board. XPS yog tiag tiag kim tshaj ib square meter dua EPS yog hais tias tus craftsmanship thiab qhov siab ntawm lub tsev raug txiav txim.
Rau thermal rwb thaiv tsev, qhov taw qhia thermal inertia D yog qhov txaus siab, thiab tus nqi D yog proportional rau thermal cia coefficient. Txawm li cas los xij, raws li tag nrho cov kev txhawj xeeb, lub peev xwm ntawm cov cua sov ntawm 200mm pob zeb yog qhov loj txaus, thiab qhov sib ntxiv ntawm txheej rwb thaiv tsev sab nrauv ua tau raws li qhov xav tau ntawm kev txuag hluav taws xob. 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. EPS lossis XPS plastering tshuab ua tau raws li qhov yuav tsum tau ua
2. Lub zog:
Lub zog qhia ntawm no yuav tsum yog lub zog tensile, thiab muaj kev sib raug zoo ntawm cov khoom ntom ntom thiab tensile lub zog ntawm cov nplooj ntawv polystyrene. Feem ntau, qhov ceev ntawm EPS yog 18Kg / m3 yog 110-120KPa, thiab qhov ntom ntom ntawm 20Kg / m3 yog li 140KPa. XPS feem ntau muaj qhov ceev ntawm 25Kg txog 45Kg thiab lub zog ntawm 150KPa txog 700KPa lossis ntau dua. (Lub ntsiab lus yog tias cov thermal conductivity ntawm 0.03 tau ntsib).
Lub zog ntawm XPS board yog 200KPa-250KPa. Feem ntau cov tuam txhab tsim khoom hauv tsev ntawm XPS pawg thawj coj saib yog 100200kpa, thiab EPS board qis dua 100KPa. Nyob rau hauv ntau thiab ntau facade kho kom zoo nkauj thiab typhoons feem ntau tshwm nyob rau hauv cov ntug hiav txwv dej, lub zog yog ib qho tseem ceeb heev, tshwj xeeb tshaj yog rau ib co Rau sab nrauv phab ntsa cib los yog siab -nce vaj tse, ob lub panels yuav tsum tau ntxiv dag zog los yog kho nrog kev pab cuam. khoom siv. Cov hlau kos duab ntawm cov vuas yuav tsum siab tshaj 400KPa. Tsis txawm tias XPS tuaj yeem them taus nws. Txoj kev daws teeb meem yog txhawm rau txhawm rau xaim mesh rau lub hauv paus txheej nrog txuas ntxiv bolts. Qhov no nthuav tawm tensile kev nyuaj siab rau hauv peb - qhov chaw seem, yog li rub- tawm kev puas tsuaj yuav tsum sib xyaw kom ntev npaum li lub thauj tog rau nkoj tau zoo. Qhov tawg-resistant mortar txheej ntawm cov hlau mesh tsis yog teeb meem loj.
Compared with EPS, XPS board has higher strength, but due to the nature of EPS board (brittleness), when the bonding area is large compared to XPS, the possibility of cracks in the outer wall finish layer, especially the paint is high . surface layer. Flexibility is a matter of the nature of the wood. In the case of facial skin, perceptual knowledge is usually applied to the polystyrene board, and then the polystyrene board is bent to such an extent that it does not break. When the flexibility is good, it will bend a few times. won't break. Similar to the ductility index of waterproofing materials. However, for the material itself, flexible EPS is superior to XPS.
3. Huab cua tsis kam:
Huab cua tsis kam yog hais txog lub peev xwm ntawm lub rwb thaiv tsev kom hloov mus rau cov kev hloov pauv sab nraud, thiab hais txog cov teeb meem zoo ntawm -, xws li kev ruaj ntseg tag nrho ntawm cov kab ke thiab cov kev hloov hauv rwb thaiv tsev los ntawm cov huab cua sib txawv. Huab cua tsis kam yog qhov taw qhia tseem ceeb heev ntawm kev rwb thaiv tsev.
Vim tias EPS boards muaj dej nqus ntau dua XPS, lawv cov huab cua tiv thaiv tsis zoo li XPS systems. Txawm li cas los xij, qhov ductility ntawm EPS boards zoo dua li ntawm XPS boards thiab tuaj yeem kov yeej qee qhov tsis zoo. Txawm li cas los xij, kom deb li deb ntawm qhov system muaj kev txhawj xeeb, txheej txheej txheej ntawm nyias plastering nws tus kheej muaj qee qhov dej tsis kam. Sib nrug los ntawm cov txheej txheem tsim kho, ob lub tshuab ua dej tsis zoo. Kev sib cuag ntawm nag thiab phab ntsa yog ntsug. Waterproofing tsis yog ib qho teeb meem ntev npaum li lub mortar ntawm qhov chaw tsis tawg.
Tsis tas li ntawd, cua siab tsis kam kuj yog ib qho tseem ceeb ntawm huab cua tsis kam, vim hais tias cov kab noj hniav ntau dua, qhov ua rau huab cua tsis zoo. Yog li ntawd, qhov ua kom pom tseeb yuav yog nyob ntawm qhov loj ntawm tag nrho thaj tsam ntawm kev sib raug zoo ntawm cov txheej txheem rwb thaiv tsev thiab lub hauv paus txheej. Tsis muaj teeb meem nrog qhov no XPS system thiab EPS system.
4. Ua pa:
Breathability and water absorption are two issues! Air molecules and water molecules are very different in size! Of course, there are breathable and airtight claims. Experiments can illustrate this. For example, in Shenzhen. Put the cookies out. You don't have to add water to the cookies. Over the course of the day, the cookie will soften as it absorbs moisture, which is water in the air rather than liquid water.
