Iintambo ezibuyiswa ngamadangatya: Oonogada abangabonakaliyo abakhusela uluntu lwale mihla

Kwihlathi lentsimbi lezakhiwo zale mihla kunye nezakhiwo zemizi-mveliso, iintambo ezingenakubalwa zixinene njengenkqubo yemithambo-luvo yomzimba womntu. Xa umlilo kwindawo ephakamileyo e-Dubai ngo-2022 wabangela ukusasazeka kweentambo eziqhelekileyo, iinjineli kwihlabathi jikelele ziphinde zagxila kwitekhnoloji ye-flame retardant yeentambo. Ingozi ebangele amashumi ezigidi zeerandi iye yatyhila inyaniso ekhohlakeleyo: phambi komlilo, iintambo eziqhelekileyo zidla ngokuba yimichiza ebulalayo. Iintambo zomlilo zibuchwephesha obuphambili kwinkalo yokhuseleko lombane, kwaye ukubaluleka kwabo akukho ngaphantsi koyilo lomlilo lwezakhiwo zokwakha. Le ntambo ekhethekileyo inokugcina isakhiwo esipheleleyo kwilangatye, inqande ngokufanelekileyo ukusasazeka komlilo, kwaye ilwela ixesha elixabisekileyo lokukhutshwa kwabasebenzi kunye nokuhlangula umlilo. "Ngumgca wokuphila" oyimfuneko kwinkqubo yokhuseleko yanamhlanje. Kwintsimi yezakhiwo eziphakamileyo eziphezulu, ukusetyenziswa kweentambo zomlilo ezivuthayo zihambelana ngokuthe ngqo nokukwazi ukukhusela intlekele kunye nokulawula. Kwinkqubo yonikezelo lwamandla kwiSakhiwo esiPhakathi saseShanghai, zonke iintambo ezithe nkqo zisebenzisa iClass B1 yokubuyiswa komlilo, kwaye intambo nganye yemitha iqulethe ngaphezulu kwe-300g ye-inorganic flame retardant filler. Olu luyilo luvumela i-shaft ye-cable ye-20-storey ukusabalalisa isantya sokusasazeka komlilo kwi-1/5 yesakhiwo esiqhelekileyo kuvavanyo lomlilo olufanisiweyo. Intambo ye-optical retardant ye-flame esetyenziswe kwisakhiwo esikrelekrele, izinto zayo ezikhethekileyo ze-sheath ziya kugwebu kwaye zandise xa zitshisa, zenze i-thermal insulation layer kunye nobubanzi obuphindwe kathathu ubukhulu bokuqala, ukukhusela ngokufanelekileyo i-fiber optical yangaphakathi ukuba yonakaliswe. Inkqubo yothutho lukaloliwe ineemfuno ezingqongqo ngakumbi ekusebenzeni kwedangatye lokubuyiswa kweentambo. Intambo yokubuyiswa komlilo esetyenziswe kwitonela kaloliwe engaphantsi komhlaba kufuneka iqinisekiswe nge-HL3 kumgangatho we-EN 45545-2, okuthetha ukuba xa intambo itshiswa kwidangatye le-800 °C, ukuxinana komsi akudluli kwi-0.5m²/s ngomzuzu. AbakwaSiemens, eJamani, baphuhlise ngokukhethekileyo intambo ekhethekileyo yokuthintela amadangatye kuloliwe ohamba ngaphantsi komhlaba waseMunich. Yamkela i-double-layer mica ibhanti yokusonga isakhiwo. Kuvavanyo lokutsha, ukuhanjiswa kokukhanya kwegesi ye-flue kuye kwahlala kuhleli ngaphezu kwe-80%, ephucula kakhulu ukubonakala kwimeko ye-tunnel.
