Ungakuvimbela kanjani ukuqhuma kothuli lwempushana
Ukuqhuma kungavinjelwa uma kokubili noma esinye sezimo Umkhawulo Weziqhumane kanye Nomthombo wokuthungela kugwenywa. Uhlelo lokumboza impushana kufanele lwenzelwe ukuvimbela zombili izimo ukwenzeka, kodwa ngenxa yobunzima bokuqeda ngokuphelele imithombo yokuthungela, ukuthembela okwengeziwe kufanele kubekwe ekuvimbeleni ukugxila kweziqhumane zempushana. Lokhu kungafezwa ngokuqinisekisa ukuthi impushana ekugxilweni komoya igcinwa ngaphansi kuka-50% we-Lower Explosive Limit(LEL). Kunqunywe ama-LEL ebangeniFunda kabanzi …
Izimbangela zokuqhuma kothuli kanye nezingozi zomlilo ngesikhathi sokukhiqiza i-powder coating
Izembatho zempushana ziyizinto ezinhle ze-organic, zingadala ukuqhuma kothuli. Kungase kuqhume uthuli lapho izimo ezilandelayo zenzeka ngesikhathi esisodwa. Imithombo yokuthungela ikhona, okuhlanganisa: (a) izindawo ezishisayo noma amalangabi;(b) ukukhishwa kukagesi noma izinhlansi;(c) ukuchithwa kwe-electrostatic. Ukuhlangana kothuli emoyeni kuphakathi kwe-Lower Explosive Limit (LEL) kanye ne-Upper Explosion Limit (UEL). lapho ungqimba lwempushana egcotshiwe noma ifu lihlangana neFunda kabanzi …
