Iintambo ezithintela ilangatye: Oonogada abangabonakaliyo abakhusela uluntu lwanamhlanje

Kwihlathi lesinyithi lezakhiwo zanamhlanje kunye nezakhiwo zoshishino, iintambo ezingenakubalwa zidibene kakhulu njengenkqubo yemithambo-luvo yomzimba womntu. Xa umlilo kwiflethi ephakamileyo eDubai ngo-2022 wabangela ukusasazeka kweentambo eziqhelekileyo, iinjineli kwihlabathi liphela zaphinda zagxila kwitekhnoloji yokuthintela amalangabi yeentambo. Ingozi eyabangela amashumi ezigidi zeerandi ityhile inyani ebuhlungu: xa kujongwe imililo, iintambo eziqhelekileyo zihlala ziba ziifusi ezibulalayo. Iintambo zokuthintela umlilo zezona teknoloji ziphambili kwicandelo lokhuseleko lombane, kwaye ukubaluleka kwazo akungaphantsi koyilo lomlilo lwezakhiwo. Le ntambo ikhethekileyo inokugcina isakhiwo esipheleleyo emalangatyeni, ithintele ukusasazeka komlilo ngempumelelo, kwaye ilwele ixesha elixabisekileyo lokufuduka kwabasebenzi kunye nokuhlangula umlilo. "Yindlela yokuphila" ebalulekileyo kwinkqubo yokukhusela ukhuseleko yanamhlanje. Kwintsimi yezakhiwo eziphakamileyo kakhulu, ukusetyenziswa kweentambo zokuthintela amalangabi kunxulumene ngokuthe ngqo nokukwazi ukuthintela nokulawula intlekele. Kwinkqubo yokubonelela ngombane yeShanghai Central Building, zonke iintambo ezithe nkqo zisebenzisa umgangatho wokuthintela amalangabi weClass B1, kwaye intambo nganye yemitha ine-filler engaphezulu kwe-300g ye-inorganic flame retardant filler. Olu yilo luvumela umngxuma wentambo onezitezi ezingama-20 ukuba usasaze isantya sokusasazeka komlilo ukuya kwi-1/5 yesakhiwo esiqhelekileyo kuvavanyo lomlilo olulinganisiweyo. Intambo ye-optical ethintela umlilo esetyenziswa kwisakhiwo esikrelekrele, izinto zayo ezikhethekileyo zesheath ziya kugqwala kwaye zande xa zitsha, zenze umaleko wokufudumala ophindwe kathathu kunobukhulu bokuqala, ukhusela ngempumelelo i-fiber yangaphakathi ekonakalisweni. Inkqubo yokuhamba ngololiwe ineemfuno ezingqongqo zokusebenza kweentambo ezithintela umlilo. Intambo ethintela umlilo esetyenziswa kwi-tunnel ye-subway kufuneka iqinisekiswe yi-HL3 kumgangatho we-EN 45545-2, oko kuthetha ukuba xa intambo itshiswa kwilangatye le-800 °C, uxinano lomsi aludluli kwi-0.5m²/s ngomzuzu. I-Siemens, eJamani, yenze ngokukodwa intambo ekhethekileyo ethintela umlilo kwi-subway yaseMunich. Yamkela isakhiwo se-mica belt wrap esineengqimba ezimbini. Kuvavanyo lokutsha, ukuhanjiswa kokukhanya kwegesi ye-flue bekusoloko kungaphezulu kwe-80%, nto leyo ephucula kakhulu ukubonakala kwindawo ye-tunnel.
