Isimiso esiyinhloko

I-Zno lighting asteris uhlobo olulodwa lwegama elithuthukisiwe ngaphezu kwesivikelo se-vllage ku-presont.duo ezingxenyeni zayo eziyinhloko zokumelana, ifaka i-Zno kanye nenye i-metal oxide ukwenza i-ot. Uma iqhathaniswa ne-carborundum asteris yendabuko, ithuthukisa kakhulu izici ze-V zokumelana, ikhulisa ikhono lokumelana, ngaleyo ndlela iletha ushintsho oluyisisekelo ezicini ze-rester.
