Ukuthintela njani ukugqabhuka kothuli lomgubo
Ugqabhuko-dubulo lunokuthintelwa ukuba zombini okanye nayiphi na imiqathango yokuqhushumba kunye noMthombo wokutshisa kuyaphetshwa. Inkqubo yokugquma umgubo kufuneka iyilwe ukuthintela zombini iimeko ukuba zenzeke, kodwa ngenxa yobunzima bokuphelisa ngokupheleleyo imithombo yokutshisa, ukuthembela ngakumbi kufuneka kubekwe ekuthinteleni ukugxila kokuqhuma komgubo. Oku kunokufezekiswa ngokuqinisekisa ukuba i-powder kwi-concentration yomoya igcinwe ngaphantsi kwe-50% ye-Lower Explosive Limit (LEL). I-LEL ezimiseleyo kuluhluFunda ngokugqithisileyo …
Izizathu zokuqhuma kothuli kunye nobungozi bomlilo ngexesha lokuvelisa umgubo
Iingubo zomgubo zezona zinto zilungileyo, zinokukhokelela ekuqhumeni kothuli. Kusenokugqabhuka uthuli xa ezi meko zilandelayo zisenzeka ngaxeshanye. Imithombo yomlilo ikhona, kuquka: (a) iindawo ezishushu okanye amadangatye;(b) izinto ezikhutshwayo zombane okanye iintlantsi;(c) izinto ezikhutshwa yi-electrostatic. Ukugxininiswa kothuli emoyeni kuphakathi koMda wokuQhubhuka okuPhantsi (LEL) kunye noMda wokuQhubhuka oPhezulu (UEL). xa umaleko womgubo wokwaleka obekiweyo okanye ilifu lidibana neFunda ngokugqithisileyo …
