Nyob rau hauv rau caum ntawm lub xyoo pua xeem, thawj tau los rwb thaiv tsev ntaub ntawv los ntawm nthuav polystyrene (EPS) ntsia. Kev ua haujlwm thawj lub tshuab hluav taws xob ua kom sov (ETICS) tam sim no nyob rau hauv qhov txheej txheem ntawm qhov xav tau kev hloov kho tshiab. Tab sis dab tsi uas ua rau lub qhov rooj thaiv rwb thaiv tsev? Pov tseg EPS thermal rwb thaiv tsev kaw lus tau txawm yog hlawv lossis pov tseg. Rov qab siv dua tshiab tseem tsis tau txog tam sim no. Tab sis qhov ntawd tsuas yog xav hloov: hauv Terneuzen, lub tebchaws Netherlands, ib qho kev sim cog ntoo tau tsim rau kev rov ua dua tshiab cov khoom siv polystyrene rwb thaiv tsev ntaub. Nrog lub peev xwm ntawm 3.000 tons nyob rau ib xyoos, yav tom ntej polystyrene rwb thaiv tsev tuaj yeem hloov mus rau hauv cov khoom lag luam zoo polystyrene rov ua dua tshiab. Kev rov qab siv dua yog siv los ua raw khoom rau cov ntaub ntawv tshiab insulating. Kev sim cog yog npaj mus rau hauv kev ua haujlwm los ntawm 2019 tam sim no.
"Txhua yam nyob qis qis hauv ntws"
Cov nroj tsuag tau raug ua los ntawm PolyStyreneLoop teg num (PS Loop Initiative) nrog kev txhawb nqa nyiaj txiag los ntawm European Commission. Hauv cov phiaj xwm no, cov tuam txhab 55 los ntawm 13 lub teb chaws tau teeb tsa lawv tus kheej hauv txoj kev sib koom tes raws li txoj cai Dutch. Xws li Austrian zoo pab pawg rau txheej txheem rwb thaiv tsev thermal (QG WDS) thiab cov chaw tsim khoom Austrotherm, Clemens Hecht, tus cev lus ntawm QG WDS: "Cov kev pib tsim yog qhov tseem ceeb vim nws kaw qhov kawg ntawm lub voj voog ntawm kev lag luam ncig! Txhua yam nyob qis qis hauv tus dej, tsis muaj ib yam yuav ploj mus.
Hauv kev koom tes nrog Fraunhofer lub koom haum IVV, CreaCycle GmbH tsim cov txheej txheem CreaSolv, uas yog siv hauv Terneuzen. Lub hauv paus ntsiab lus yog "xaiv xaiv". Hauv cov txheej txheem patented, impurities thiab kuab paug tau sib cais los ntawm cov txheej txheem ntxuav tshwj xeeb. Raws li cov neeg tsim tawm, cov peev xwm tshwj xeeb ntawm cov txheej txheem nyob hauv kev ua kom huv ntawm cov khoom ntawm qib molecular. Cov txiaj ntsig zoo-cuam tshuam rau kev ua kom tsis zoo (xws li kua nplaum) yog li tshem tawm maj mam muab thiab thaum khaws cov khoom polymer. "Lub hnab yas siv rov qab los ntawm cov khoom sib xyaw nrog cov khoom sib xyaw lossis cov khoom siv sib xyaw ua rau pom cov khoom siv nkauj xwb," lub koom haum Fraunhofer tau piav qhia ntawm CreaSolv®. Nws kuj tseem tuaj yeem txhais tau qhov tam sim no tau muab cais ua qhov lom tua hluav taws hexabromocyclododecane (HBCD) thiab rov siv dua li bromine. Txawm hais tias HBCD tsis siv txij li 2015, nws tseem muaj nyob hauv cov khoom qub. Austrotherm Tswj Tus Thawj Coj Gerald Prinzhorn: "Rau ETICS, kev rhuav tshem thiab rov ua dua tshiab tsis yog qhov tseem ceeb. Cov khoom siv insulating muaj qhov sib koom ua ke ntau tshaj plaws thiab yog li yuav tsum rov ua dua tshiab mus rau 100 feem pua. Cov khoom muag muag thiab coj rov qab tuaj yeem siv rau cov khoom lag luam tshiab tom qab cov txheej txheem hais dua dua 1: 1. "
Kev tsim kho kev lag luam tuav ntau lub peev xwm
Kev txaus siab ntawm kev ua kom ruaj khov, txawm li cas los xij, tseem muaj lwm txoj hauv kev xaiv ua rau cov thermal rwb thaiv tsev tiv thaiv txheej txheem: Lub façade rwb thaiv tsev tsis ua tiav cov kua nplaum uas tuaj yeem siv rau nws cov khoom tseem ceeb tau tsim los ntawm cov khw muag khoom hauv kev koom tes nrog Graz University of Technology. Thaum rhuav tshem cov kab ke, cov kab ke hauv lub tshuab tuaj yeem sib cais dua txheeb thiab rov ua dua tshiab. Vim tias cov khoom xyaw yog nce es tsis txhob glued. "Cov thev naus laus zis no ua rau peb lub tshiab façade rwb thaiv tsev kaw lus StoSystain-R lom zem ntau siv thiab rov ua dua tshiab hauv nws cov khoom tseem ceeb," Walter Wiedenbauer, Tus Thawj Tswj ntawm Sto. "Qhov no yog kev tawg nyob rau hauv kev ua tau ruaj khov uas yuav txawm muab lub tswv yim txhim kho kev lag luam."
Rau Greta Sparer, tus poj niam hais rau RepaNet - Re-Kev Siv & Kho Network Austria, kev tsim kho tshiab zoo siab tos txais, tab sis tsis deb txog: “RepaNet txais tos txoj hauv kev lag luam tshiab. Hauv kev tsim kho kev lag luam tshwj xeeb, tseem muaj ntau yam peev txheej ntawm no thiab qhov haujlwm ntawm lub ntsej muag ntsej muag tsis muaj qhov nplaum thiab nrog kev sib cais zoo dua thiab rov ua dua tshiab yog qhov kev txhim kho zoo los ntawm qhov tam sim no. Cov kauj ruam tom ntej yuav tsum yog cov txheej txheem rwb thaiv tsev tuaj yeem rov qab siv dua, vim qee qhov peev txheej yeej ib txwm ploj thaum rov siv dua. "
