Lub scientific paub tsis meej ntawmpolystyrene board

Polystyrene board yog tsim los ntawm 98% huab cua thiab 2% polystyrene. Nws yog precisely no me me khoom moj khaum uas ntxiab ib tug loj npaum li cas ntawm cov huab cua tseem, tsim ib tug zoo heev rwb thaiv tsev txheej. Cua yog ib qho hluav taws xob tsis zoo heev. Cov kab hluav taws xob uas raug kaw no ua kom muaj kev tiv thaiv thermal zoo nrog cov thermal conductivity tsuas yog 0.032-0.038W/(m·K). Qhov no txhais li cas? Piv nrog rau cov khoom siv hauv tsev: Cov nyhuv rwb thaiv tsev ntawm 10{10}}cm- tuab polystyrene board yog sib npaug ntawm 1.5-meter-thick phab ntsa lossis 1.2-meter-thick phab ntsa!

Lub ntsiab zoo ntawm polystyrene board

Qhov zoo tshaj plaws kev txuag hluav taws xob

Lub kaw-cov qauv ntawm tes ntawm polystyrene board zoo tiv thaiv tshav kub convection, txo qhov cuam tshuam ntawm tus choj thermal, thiab tswj qhov kub thiab txias ntawm lub tsev. Hauv kev siv tswv yim, cov tsev siv polystyrene board sab nrauv phab ntsa rwb thaiv tsev tuaj yeem txo cov cua sov siv hluav taws xob los ntawm 50-70% nyob rau lub caij ntuj no thiab cua txias zog siv los ntawm 40-60% nyob rau lub caij ntuj sov.

Qhov zoo tshaj plaws kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig

Los ntawm qhov kev xav ntawm tag nrho lub neej kev ntsuam xyuas, lub zog siv nyob rau hauv zus tau tej cov polystyrene boards yog npaum li cas qis dua lub zog txuag thaum lawv siv theem. Rau txhua qhov cubic meter ntawm polystyrene board rwb thaiv tsev cov ntaub ntawv siv, kwv yees li 3,000 litres ntawm cov roj hluav taws xob tuaj yeem txuag tau thiab kwv yees li 7.5 tons ntawm carbon dioxide emissions yuav raug txo thaum lub sij hawm nws lub neej 20 xyoo. Qhov no yog sib npaug rau cov pa roj carbon emissions ntawm lub tsheb mus txog 30,000 kilometers

Lub cev muaj zog ntawm qhov hnyav thiab siab - lub zog

Qhov ntom ntawm polystyrene board feem ntau yog nruab nrab ntawm 15 thiab 30kg / m³, uas yog 1/50 ntawm cov pob zeb thiab 1/40 ntawm cov phab ntsa cib, txo cov load ntawm lub tsev. Lub caij no, nws lub zog compressive tuaj yeem ncav cuag 100-150 kpa, uas yog txaus los dais qhov hnyav ntawm sab nrauv phab ntsa plastering txheej thiab cov txheej txheem zoo nkauj.

Ntev - ua haujlwm tau ntev thiab ruaj khov

High- zoo polystyrene boards muaj kev tiv thaiv zoo - kev laus. Raws li kev txhim kho thiab kev saib xyuas kom raug, lawv lub neej kev pabcuam tuaj yeem ncav cuag 50 xyoo. Nws cov rwb thaiv tsev kev ua tau zoo qeeb qeeb qeeb heev thaum lub sijhawm, thiab nws tseem tuaj yeem tswj tau ntau dua 90% ntawm nws cov nqi hluav taws xob pib tom qab 20 xyoo.

Zoo sib npaug ntawm noo noo tsis kam thiab breathability

Qhov kaw -cov xov tooj ntawm tes ntawm polystyrene board yog tshaj 95%, tiv thaiv cov kua dej los ntawm kev nkag mus tau zoo. Nyob rau tib lub sijhawm, nws tso cai rau cov dej vapor hla me ntsis, tsis txhob muaj qhov sib xyaw ua ke hauv cov phab ntsa thiab ua kom lub tsev tsim kom qhuav thiab noj qab nyob zoo.

Txhim kho kev nyab xeeb ntawm hluav taws

Los ntawm kev ntxiv cov nplaim hluav taws (feem ntau yog hloov rau hexabromocyclododecane), polystyrene boards tuaj yeem ua tau raws li B1 qib nplaim hluav taws- cov khoom siv retardant. Qhov tseem ceeb tshaj, txoj kev txhim kho kom raug yuav tsum tau siv cov hlua hluav taws xob sib cais ntawm txhua lub hauv pem teb thiab cov pob zeb wool fireproof seals siv nyob ib ncig ntawm lub Windows kom ua tiav thiab ua kom muaj kev nyab xeeb ntawm lub tsev.

Daim ntawv thov kiv puag ncig ntawmpolystyrene boardhauv vaj tse ntsuab

Raws li lub hom phiaj ntawm lub ntiaj teb carbon neutrality, polystyrene boards tau dhau los ua lub hauv paus thev naus laus zis rau cov tsev tsis muaj zog thiab xoom- lub tsev hluav taws xob. Tus qauv German passive lub tsev xav kom txhua xyoo cua sov lub zog siv ntawm cov tsev yuav tsum tsis txhob ntau tshaj 15kWh / m², uas yog yuav luag ib tug -feem kaum ntawm cov vaj tsev zoo tib yam nyob rau hauv Tuam Tshoj! Lub hauv paus rau kev ua tiav lub hom phiaj no yog nyob rau hauv kev tsim ntawm ib qho ultra- tuab polystyrene board rwb thaiv tsev txheej (feem ntau 20-40 centimeters) ua ke nrog huab cua nruj.

 

Cov ntaub ntawv thov tshiab: Hauv "Carbon Neutrality Demonstration Community" hauv Shanghai, architects siv 30-centimeter-tick graphite polystyrene board (NEOPOR®) rau sab nrauv phab ntsa rwb thaiv tsev, ua ke nrog peb-txheej iav qhov rais thiab cov cua sov rov qab cua tshiab, txo lub tsev 5% kev siv cua sov txhua xyoo. Lub zej zog no txo ​​cov pa roj carbon monoxide los ntawm kwv yees li 1,200 tons txhua xyoo, uas yog sib npaug rau cog 65,000 tsob ntoo!

Cov kev txhawj xeeb tseem ceeb ntawm cov neeg hais txog polystyrene boards tsom rau kev nyab xeeb hluav taws thiab kev ruaj ntseg ib puag ncig. Niaj hnub nimno polystyrene board technology tau ua tiav kev vam meej:

Kev tsim kho tshiab hauv kev lag luam ncig: Kev siv thev naus laus zis ntawm polystyrene boards tau dhau los ua neeg paub tab. Kev siv lub cev tuaj yeem rov ua dua cov ntaub ntawv pov tseg polystyrene rau kev tsim cov khoom siv hluav taws xob tsawg lossis cov khoom ntim khoom. Kev siv tshuaj lom neeg tuaj yeem depolymerize polystyrene rau hauv cov monomers thiab rov ua dua - tsim cov pob zeb zoo nkauj polystyrene. Tus nqi rov ua dua ntawm polystyrene boards hauv Tebchaws Europe tau nce los ntawm 25% hauv 2010 txog 48% hauv 2023, nrog lub hom phiaj kom ncav cuag 65% los ntawm 2030.
Bio-raws li lwm txoj kev: Txiav- kev tshawb fawb ntug tab tom tsim lwm txoj hauv kev rau bio-raws li polystyrene boards, xws li polylactic acid foamed cov ntaub ntawv muab rho tawm los ntawm pob kws thiab qab zib. Txawm hais tias tus nqi tam sim no kuj yog siab heev, nws taw qhia cov kev taw qhia rau cov khoom siv rwb thaiv tsev txuas ntxiv dua tshiab rau yav tom ntej.

Cov lus hais tias "peb qhov khoom siv, xya qhov kev tsim kho" yog pom tseeb nyob rau hauv cov txheej txheem polystyrene board rwb thaiv tsev. Qhov tseeb installation muaj xws li:

Kev kho lub hauv paus: Cov phab ntsa saum npoo yuav tsum huv thiab du, kom ntseeg tau tias thaj chaw sib txuas ntau dua 40%
Interlaced tiling: Lo rau lawv ntawm staggered seams zoo li nteg cib kom txo tau cov choj thermal
Anchoring reinforcement: Tsis pub tsawg tshaj 6 lub tsheb thauj tog rau nkoj bolts ib square meter, nrog rau cov cua kub siab tiv thaiv kev nyab xeeb ntawm ntau dua los yog sib npaug rau 1.5
Kev kho kev sib koom ua ke: Kev sib koom ua ke ntawm lub rooj tsavxwm yuav tsum tau tswj tsis pub dhau 2 hli thiab ntim nrog cov nplaum nplaum los yog rwb thaiv tsev
Kev tiv thaiv txheej txheem: Alkali-cov iav fiber ntau mesh npuag yog embedded rau hauv plastering mortar los txhim kho kev cuam tshuam
Ib qho kev nkag siab tsis zoo yog tias "polystyrene boards yuav ua rau phab ntsa airtight." In fact, the water vapor wet flow density of high-quality polystyrene board systems can reach 1.5g/(m²·h), which is higher than the 0.5g/(m²·h) of traditional brick walls, ensuring the healthy breathing of the walls.

Raws li Suav lub teb chaws tus qauv GB / T 10801.1-2021, EPS boards rau kev tsim kho yog muab faib ua rau qib (los ntawm 080 mus rau 250) raws li compressive zog, peb qib (los ntawm 2% mus rau 5%) raws li dimensional stability, thiab peb qib B1, B2, thiab B3 raws li combustion kev ua tau zoo. EU tus qauv EN 13163 tau txais kev faib tawm ntau dua, suav nrog 10 qhov ntsuas kev ua haujlwm tseem ceeb.
