Kwiminyaka engamashumi amathandathu anesithandathu, eyokuqala yaba izinto ukwahlukanisa ukusuka ekwandisweni istro (I-EPS) ifakiwe. Iinkqubo zokufakelwa kolungelelwaniso lokuqala lwezinto zokuthambisa (i-ETICS) ngoku zikwinkqubo yokufuna ukuhlaziywa. Kodwa yintoni ekufuneka yenziwe iibhodi zokugquma ezilahliweyo? Iinkqubo zokulahla i-EPS ezilahliweyo zitshisiwe okanye zilahlwa. Ukuphinda kusetyenziswwe ngokutsha akunakwenziwa kude kube ngoku. Kodwa loo nto sele iza kutshintsha: eTerneuzen, eNetherlands, kusakhiwa umatshini ongumqhubi wokuphinda usebenzise izinto zokufakelwa zepolystyrene. Ngomthamo weetoni ze-3.000 ngonyaka, ukufakelwa kwe-polystyrene yexesha elizayo kungaguqulwa kube yinto ephakamileyo ye-polystyrene recyclate. Ukuphinda usebenzise isetyenzisiweyo njengesixhobo esikrwada kwizixhobo ezintsha zokufakelwa. Umatshini wokuvavanya ucwangciselwe ukuya kusebenza yi2019 yakutshanje.
Yonke into ihlala ibaleka "
Esi sityalo siyenziwa ngephulo lePolyStyreneLoop (Initial ye-Loop ye-PS) ngenkxaso yemali kwiKhomishini yaseYurophu. Kweli phulo, iinkampani ze55 ezivela kumazwe e-13 zizilungiselele ngendlela yokubambisana phantsi komthetho waseDatshi. Ukubandakanya iqela lase-Austrian elisemgangathweni weenkqubo zokufakelwa kobushushu (QG WDS) kunye nomenzi Austrotherm, UClemens Hecht, isithethi seQG WDS: "Eli phulo libaluleke kakhulu kuba livala inxalenye yokugqibela yesangqa soqoqosho! Yonke into ihlala emlanjeni, akukho nto ilahlekileyo. "
Ngokusebenzisana neFraunhofer Institute IVV, iCroaCycle GmbH iphuhlise inkqubo yeCroaSolv, esetyenziswa eTerneuzen. Isiseko esisiseko "sisiseko esikhethiweyo". Kwinkqubo enelungelo elilodwa lomenzi wechiza, ukungcola kunye nokungcola kwahlukaniswa ziinkqubo ezizodwa zokucoca. Ngokomqambi, amandla akhethekileyo enkqubo axhomekeke ekucoceni kwezinto kwimolekyuli. Ukungcola okuchaphazela umgangatho (njengeglue) kususwa ngobunono ngelixa kulondolozwa iipropathi zepolymer. "Iplastiki ezihlaziyiweyo ezivela kumxube oxutywe okanye izinto ezenziwe ngezinto ezibonakalayo zibonisa iipropathi zezinto ezizezentombi," kubhala uFraunhofer Institute kwinkcazo yeCroaSolv ®. Ingathetha into ehlelwe ngoku njengeyityhefu yokubuyisela umlilo hexabromocyclododecane (HBCD) yaphinda yasetyenziswa njenge-bromine. Nangona i-HBCD ingasasetyenziswanga ukusukela kwi2015, isekhona kwisitokhwe esidala. Austrotherm Umlawuli olawulayo uGerald Prinzhorn: "Kwi-ETICS, ukudilizwa kunye nokurisayikilisha ayisosihloko. Izinto zokufakelwa zinesabelo esikhulu senkqubo kwaye ke kufuneka iphinde iphinde iphinde iphindwe ipesenti ye-100. Imveliso ethengisiweyo nebuyisiweyo ingasetyenziselwa iimveliso ezintsha emva kwenkqubo ekhankanyiweyo kwakhona i1: 1. "
Umzi-mveliso wokwakha ubamba okuninzi okunokwenzeka
Ngomdla wokuzinza, nangona kunjalo, kukho ezinye iindlela ezizezinye zeenkqubo eziqhelekileyo zokufakelwa kwamandla okufudumeza: Inkqubo ye-façade insulation engenasiphelo yeglue enokuphinda isetyenziselwe izinto zayo eziphambili yaphuhliswa ngumvelisi uSto ngokubambisana neYunivesithi yeTekhnoloji ye-Graz. Xa ubhubhisa inkqubo, izinto zenkqubo ziyahlulahluleke ziphinde zihlelwe kwaye ziphinde zisetyenziswe kwakhona. Kuba izithako zinyuka endaweni ye-glued. "Obu buchwephesha benza inkqubo yethu yokufakelwa ngokutsha ye-fancade Sto Stoyystain-R iphinde isebenze kwakhona kwaye iphinde isebenze kwakhona kumacandelo ayo aphambili," utshilo uWalter Wiedenbauer, uMlawuli olawulayo weSto. "Olu lunkqutyana kuzinzo olunokuthi lutshintshe nemveliso."
NgeGreta Spider, isithethi sika RepaNet -Sebenzisa kwakhona kwaye ulungise iNethiwekhi yase-Ostriya, ezo zinto zintsha zamkelekile, kodwa azifikeleli ngokwaneleyo: “I-RepaNet yamkela ngokubanzi iindlela ezintsha zoqoqosho olujikelezayo. Kukho okuninzi okunokubakho apha, ngakumbi kwishishini lokwakha, kunye neprojekthi yokugquma i-facade ngaphandle kokuncamathela kunye nokwahlula okungcono kunye nokuphinda kwenzeke kwakhona luphuhliso oluqinisekileyo ukusuka kwindawo yangoku. Inyathelo elilandelayo kufuneka ukuba izinto zokugquma zinokusetyenziswa kwakhona xa zizonke, kuba ezinye zezixhobo zihlala zilahleka xa kusetyenzwa kusetyenziswe kwakhona. "
