Fotokatalisi y'urumuri rugaragara ni iki?
Gutunganya urumuri rugaragara bivuga okiside y’urumuri rugaragara no kwangirika kwa photocatalyst mu gihe cy’urumuri rugaragara.
Ni iyihe ngingo ngenderwaho yo gukoresha fotokatalisi y'urumuri rugaragara?
Ihame ry’urumuri rugaragara rishingiye ku irangi ry’urumuri rugaragara, umugozi w’urumuri rwa catalyst valence unyura mu gice cy’urumuri, ujya mu gice cy’urumuri, ugakora umwobo n’urumuri bya elegitoroniki, umwobo w’urumuri hamwe n’uturemangingo tw’amazi kugira ngo hakorwe radicals za hydroxyl free, electron na molecule ya ogisijeni bitanga anion ya super ogisijeni, n’imyobo, radicals za hydroxyl na superoxide anion. Ubwoko bwa ogisijeni bushobora kwangiza molecules z’impumuro mbi, ibintu bikomoka ku bimera, bagiteri n’ibindi bihumanya mu mazi na dioxyde de carbone n’utundi turemangingo duto. Ingano nto ya N, S na P mu bintu bikomoka ku bimera izakora nitrate, sulfate, fosifate n’ibindi nyuma yo kwangirika, kugira ngo bigire ingaruka ku gusukura, gukuraho impumuro mbi no kuvura indwara. Ikoranabuhanga rigaragara ryo gusiga urumuri ritanga igisubizo gishya cy’icyatsi kibisi cyo kuvura ikirere cyo mu nzu no hanze.
Kuki ukoresha fotokatalisi y'urumuri rugaragara?
Dukurikije ibisobanuro biri mu gipimo cy’igihugu cya GB/T 17683.1-1999, urumuri rwa ultraviolet mu zuba rungana na 7% gusa, urumuri rugaragara rungana na 71%, naho infrared ingana na 22%. Nubwo ingufu za fotoni ya ultraviolet ari nini kurusha iz’urumuri rugaragara cyangwa urumuri rwa infrared, urumuri rugaragara n’urumuri rwa infrared "bitsinda" umubare. Ikoranabuhanga rya oxidation rya fotocatalytic risanzwe rikorwa gusa n’urumuri rwa ultraviolet rwangiza imyanda ya organic. Kandi jiangyin day state quantum coating technology co., LTD. Umusaruro w’ibikoresho by’ikoranabuhanga rya oxidation rya catalytic rya light rigaragara na TiO2 yo ku rwego rwa quantum, imikorere yaryo ishobora kubaho atari mu kwangirika kwa oxidation ya fotocatalytic gusa, ahubwo ishobora no kwangirika kwa oxidation ya catalytic munsi ya ultraviolet na infrared, ni igisubizo gishya cyuzuye cy’ikoranabuhanga rya photocatalytic, cyanogeje cyane imikorere.
