Zingwe zotsekereza moto: Alonda osawoneka omwe amateteza anthu amakono

M'nkhalango zachitsulo za nyumba zamakono ndi mafakitale, zingwe zosawerengeka zimalumikizana kwambiri ngati dongosolo lamanjenje la thupi la munthu. Pamene moto m'nyumba yapamwamba ku Dubai mu 2022 unayambitsa kufalikira kwa zingwe wamba, mainjiniya padziko lonse lapansi adayang'ananso paukadaulo woletsa moto wa zingwe. Ngozi yomwe idayambitsa madola mamiliyoni ambiri yavumbula zenizeni zankhanza: pamaso pa moto, zingwe wamba nthawi zambiri zimakhala zophatikizika. Zingwe zozimitsa moto ndizo ukadaulo wapamwamba pantchito yachitetezo chamagetsi, ndipo kufunikira kwawo sikuchepera kuposa kapangidwe ka moto kamangidwe kanyumba. Chingwe chapaderachi chimatha kusunga dongosolo lathunthu mumoto, kuchepetsa kufalikira kwa moto, ndikuyesetsa nthawi yamtengo wapatali kuti anthu asamuke ndi kupulumutsa moto. Ndi "njira yopulumutsira" yofunikira kwambiri pachitetezo chamakono chachitetezo. M'munda wa nyumba zazitali kwambiri, kugwiritsa ntchito zingwe zotchingira moto kumakhudzana mwachindunji ndi kuthekera kwa kupewa ndi kuwongolera masoka. M'magawo amagetsi a Shanghai Central Building, zingwe zonse zoyimirira zimagwiritsa ntchito Class B1 retardant standard, ndipo chingwe chilichonse cha mita chimakhala ndi zodzaza zopitilira 300g za inorganic flame retardant. Kapangidwe kameneka kamalola chingwe cha 20-storey shaft kufalitsa liwiro la moto kufalikira ku 1/5 ya nyumba yokhazikika muyeso loyesa moto. Chingwe choyang'ana moto chomwe chimagwiritsidwa ntchito mnyumbayo mwanzeru, zinthu zake zapadera za m'chimake zimatha kuchita thovu ndikuwonjezedwa poyaka, ndikupanga wosanjikiza wotenthetsera wokhala ndi mainchesi atatu kukula kwake, kuteteza bwino ulusi wamkati wamkati kuti usawonongeke. Dongosolo la njanji lili ndi zofunika zokhwimitsa kwambiri kuti zingwe zisamagwire ntchito yoletsa moto. Chingwe chotchingira moto chomwe chimagwiritsidwa ntchito mumsewu wapansi panthaka chiyenera kukhala chovomerezeka HL3 mu EN 45545-2 muyezo, zomwe zikutanthauza kuti chingwe chikawotchedwa pamoto wa 800 ° C, kuchuluka kwa utsi sikudutsa 0.5m²/s pamphindi. Siemens, Germany, anakonza mwapadera chingwe chapadera choziziritsa moto cha njanji yapansi panthaka ya Munich. Imatengera kapangidwe kawiri wosanjikiza lamba wa mica. Poyesa kuyaka, kuwala kwa gasi wa flue kwakhalabe pamwamba pa 80%, zomwe zimathandizira kwambiri kuwoneka bwino mumsewu.
