Amathayela njengesihlungi somoya
Abacwaningi eNyuvesi yaseCalifornia, e-Riverside benze ama-roof shingles abathi angakwazi ukubola ngamakhemikhali inani elifanayo lama-nitrogen oxides ayingozi emkhathini phakathi nonyaka njengoba imoto evamile ishayela ngaphezu kuka-17 ngesikhathi. amakhilomitha. Ngokokunye ukulinganisa, uphahla oluyisigidi olumbozwe ngamathayela anjalo lususa amathani ayizigidi eziyi-21 alawa ma-oxides emoyeni ngosuku.
Isihluthulelo sokufulela ngokuyisimangaliso yingxube ye-titanium dioxide. Abafundi abaqhamuke nalo msunguli bavele bahlanganisa ngawo amathayela ajwayelekile, athengwa ezitolo. Ngokunembayo, bazimboza ngezendlalelo ezihlukene zalesi sici, bezivivinya "ekamelweni lomkhathi" elenziwe ngamapulangwe, amapayipi eTeflon kanye ne-PVC. Bampompa izakhi ze-nitrogen eziyingozi ngaphakathi futhi bakhanyisa amathayili ngemisebe ye-ultraviolet, eyenza i-titanium dioxide isebenze.
Kumasampula ahlukahlukene, ukunamathela okusebenzayo kususiwe kusuka kumaphesenti angama-87 kuye kwangama-97. izinto eziyingozi. Kuyathakazelisa ukuthi ubukhulu bophahla olunongqimba lwe-titanium alwenzanga umehluko omkhulu ekusebenzeni kahle kokusebenza. Nokho, leli qiniso lingase libaluleke ngokombono wezomnotho, njengoba izingqimba ezincane ze-titanium dioxide zingasebenza. Abaqambi njengamanje bacubungula ukuthi kungenzeka "ukufaka amabala" ngale nto zonke izindawo zezakhiwo, okubandakanya izindonga nezinye izakhi zezakhiwo.
