Technological nthuav polystyrene, uas yog cov khoom siv niaj hnub nrog ntau cov khoom siv tau zoo, tau txais lub npe ntawm cov rwb thaiv tsev tshwj xeeb. Nws yog dav siv hauv cov khoom siv tu cev, kev tsim kho, kev ua haujlwm thiab ntau qhov chaw. Cov khoom no tau paub ntau tshaj 60 xyoo. Nws tseem hu ua extruded polystyrene.
Nws yog cov yas uas muaj cov qauv zoo sib xws ntawm cov qe kaw me me nrog qhov loj txog li 0.2 hli. Yuav kom tau txais ib daim ntawv ntawm cov khoom no, kev kub siab thiab kub yog siv rau cov khoom siv raw, uas cov granules yog tov nrog ib txhij qhia ntawm ib tug foaming neeg sawv cev. Lawv tuaj yeem yog carbon dioxide lossis sib xyaw ntawm lub teeb freon. Tom qab ntawd, cov khoom siv raw yog nyem tawm ntawm extruder, vim li ntawd, cov nplooj ntawv xim lossis pob tshab tau txais, uas, tom qab ziab, npaj siv.
Kev piav qhia
EPS - rwb thaiv tsev, uas muaj cov thermal rwb thaiv tsev siab thiab lub zog muaj zog. Nws muaj cov tshuaj muaj feem cuam tshuam nrogua npuas ncauj, vim cov ntaub ntawv no muaj ib tug yawm txiv - polystyrene. Txawm li cas los xij, nyob rau hauv cov nqe lus ntawm kev ua haujlwm, extruded polystyrene ua npuas ncauj tsis tuaj yeem muab piv nrog cov npuas dej zoo tib yam, vim nws yog ua ntej ntawm nws cov khoom siv polymer. Yog vim li cas rau qhov no nyob rau hauv lub hauv paus sib txawv nyob rau hauv ntau lawm technology. Styrofoam tsis dhau ntawm extruder, tab sis XPS ua.
Cov polymer los ntawm extrusion tau txais kev hloov pauv txawv, thiab yog li lwm yam zoo thiab cov khoom. Ua ntej, cov granules yaj thiab tsim ib homogeneous viscous loj. Cov khoom nyoos dhau los ntawm lub xeev khov rau hauv ib qho viscous. Cov kev hloov pauv ntxiv tuaj nrog cov khoom ua kua-theem uas muaj cov ntawv cog lus sib txuas.
Specifications
EPS yog lub rhaub dej kub uas muaj qee yam kev ua haujlwm. Yuav kom nkag siab txog lawv, nws yog ib qho tsim nyog yuav tau xav txog cov khoom siv kom ntxaws. Lub luag haujlwm ntawm txhua lub tshuab cua sov yog khaws cov cua sov hauv chav. Txij li thaum tus nqi ntawm tshav kub hloov pauv txawv raws li cov kev cai ntawm thermodynamics nyob ntawm seb qhov ntom ntawm cov khoom, cov pa roj muaj cov thermal conductivity qis dua piv rau cov khib nyiab.
Lub thermal conductivity ntawm huab cua yog 0.026 W / m° C. Penoplex muaj cov cua sib tov ntawm 90%, nyob rau hauv kev twb kev txuas nrog rau qhov no, qhov taw qhia hais saum toj no yog 0.030 W / m° C. Qhov txawv yog tsawg, qhov no qhia tau hais tias muaj peev xwm khaws tau cov cua sov. Kev nthuav dav polystyrene tuaj yeem muaj qhov sib txawv, uas sib txawv rau cov khoom sib txawv xws li 25 txog 47 kg / m 3. Qhov ntsuas no cuam tshuamlub zog, uas, nrog nce ceev, tuaj yeem sib npaug li qhov txwv ntawm 20,000 txog 50,000 kg / m2.
EPS - lub rhaub uas tsis nqus dej zoo. Rau 28 hnub, lub phaj yuav nqus tau li 0.4% ntawm cov kua los ntawm nws lub ntim, tom qab uas cov txheej txheem nres kiag li. Lub vapor permeability ntawm no thermal rwb thaiv tsev yog 0.0128 Mg / (mhPa). Qee lub sij hawm cov cuab yeej no suav nrog qhov xav tau ntxiv txheej ntawm vapor barrier thaum txhim kho tus kheej.
hom rwb thaiv tsev no tuaj yeem siv tau nyob rau hauv yuav luag txhua qhov kev nyab xeeb vim muaj peev xwm tiv taus qhov kub thiab txias ntawm - 50 txog + 75 ˚С.
EPS - rwb thaiv tsev, uas yog tus cwj pwm los ntawm combustibility y. Nyob ntawm seb cov nplaim hluav taws kub zoo li cas ntxiv rau nws, chav kawm flammability tuaj yeem sib txawv ntawm G1 txog G4. Ntawm kev muag khoom koj tuaj yeem pom qee lub npe ntawm cov khoom siv piav qhia, uas muaj L-shaped notch raws ntug. Nws yog tsim nyog rau ib tug snug haum ntawm cov khoom rau ib leeg los ntawm ntxiv dag zog rau lub rwb thaiv tsev ntawm seams. Qhov tshwj xeeb no tiv thaiv kev tsim cov txuas hniav txias ntawm cov phiaj.
Penoplex tau koom nrog hauv kev sim uas cuam tshuam rov qab khov thiab thawing. Feem ntau ntawm cov kev ntsuam xyuas tau ua kom pom tseeb tias lub qhov cub tuaj yeem tiv taus mus txog 80 lub voj voog, hauv kev xyaum cov duab no sib raug rau qee lub xyoo ntawm kev ua haujlwm.
Yog tias peb sib piv cov khoom piav qhia nrog nws cov khoom sib xws - polystyrene ua npuas ncauj, ces qhov sib txawv ntawm qhov sib txawv. Lawv tshwm sim los ntawm kev siv cov cuab yeej tshwj xeeb hauv cov txheej txheem ua npuas dej,uas tso cai rau koj ua kom cov nplooj ntawv muaj zog thiab nyias. Txhawm rau kom ua tiav cov txiaj ntsig zoo ib yam, cov txheej ua npuas dej yuav tsum tau muab ob npaug rau piv rau cov npuas npuas. Ntawm lwm yam, nteg yuav tsum tau ua nyob rau hauv ob kab kom cov choj txias tsis tsim nyob rau hauv lub cheeb tsam ntawm seams.
Thaum sib piv nthuav dav polystyrene nrog rau lwm cov ntaub ntawv rwb thaiv tsev nyob rau hauv cov nqe lus ntawm lub suab kis tau tus mob, peb tuaj yeem txiav txim siab tias cov khoom poob hauv qee qhov kev hwm, txawm li cas los xij, ntawm kev yooj yim ntawm kev teeb tsa, qhov no nws tsis muaj qhov sib npaug. Qhov no yog vim nws yooj yim dua rau nteg cov nplooj ntawv nyuaj dua li nws yog ua haujlwm nrog cov ntaub plaub mos mos.
Cov lus qhia tshwj xeeb ntawm cov lus qhia
Thaum lub sij hawm tsim tsev sauna lossis da dej, extruded polystyrene ua npuas ncauj yuav tsum tsis txhob siv rau rwb thaiv tsev. Qhov no yog vim lub fact tias nws cov yam ntxwv tsis tso cai rau tso cov khoom nyob rau hauv tej yam kev mob uas kub nyob rau hauv lub chav tsev yog siab tshaj + 75 ˚С. Txawm li cas los xij, extruded polystyrene ua npuas ncauj yuav siv tau nyob rau hauv yuav luag txhua qhov chaw ntawm kev tsim kho kev lag luam. Nyob rau hauv rooj plaub no, lub cheeb tsam uas cov khoom nyob rau hauv tsis muaj teeb meem.
Cov rwb thaiv tsev no ua haujlwm zoo ntawm lub sam thiaj me lossis loggia ntawm chav tsev, nrog rau hauv cov phab ntsa ntawm lub khw loj loj. Hauv qhov no, kev siv extruded polystyrene ua npuas ncauj yog qhov ncaj ncees.

XPS extruded polystyrene ua npuas ncauj muaj cov nram qab no qhov ntev: 1005801180mm. Thermal conductivity yog λ25. Rau packing koj yuav them 1430 rubles. Cov khoom siv yog siv nyob rau hauv qis-nce thiab tsev tsim kho rau thermal rwb thaiv tsev ntawm lub hauv paus, pem teb, qhov muag tsis pom kev, facade, hauv qab daus thiab ru tsev. Thermal rwb thaiv tsev yog qhov tseem ceeb rau kev rwb thaiv tsev ntawm lub tsev nrog lub ru tsev tiaj tus. Qhov no EPS, tus nqi uas pheej yig, yog qhov kev daws teeb meem zoo tshaj plaws rau insulating lub tsev los ntawm lub hauv paus mus rau lub ru tsev. Thermal rwb thaiv tsev tsis nqus noo noo, ntsws los yog o.
Cov txiaj ntsig ntxiv suav nrog kev ruaj ntseg lom neeg thiab qhov ruaj khov. XPS los ntawm TechnoNIKOL yog lub zog txuag thiab tus phooj ywg ib puag ncig. Nws yog ruaj khov thiab muaj dej tsawg tsawg.
Ntawm ntawm Styrofoam Extruded Styrofoam
Cov khoom siv no muaj ntau yam, txhua tus siv rau lub hom phiaj sib txawv. Piv txwv li, qib 250-A yog tsim rau peb-txheej phab ntsa thiab pitched ru tsev rwb thaiv tsev. 300-A tuaj yeem siv rau kev hloov pauv thiab cov ru tsev tiaj tus. Qhov chaw tsim khoom no 500-A-cim XPS extruded polystyrene ua npuas ncauj yog siv rau kev kho lub ru tsev, rwb thaiv tsev txias, thiab cov plag tsev hnyav. Siv cov khoom cim 350-Atuaj yeem siv los cais cov lem thiab cov kis las. Qhov nominal ntom nyob rau hauv cov ntaub ntawv no yog 34 kg/m3. Styrofoam extruded polystyrene ua npuas ncauj muaj nyob rau hauv 700-A ntau, uas yog tsim los rau insulate lub hauv paus thiab lub hauv paus nyob rau hauv siab dynamic thiab zoo li qub loads.
Penoplex nqi
