I-DRK453 Impahla ekhuselayo ye-anti-asidi kunye nenkqubo yokuvavanya i-alkali-impahla ekhuselayo yokungena ngexesha lokuvavanya
Inkcazelo emfutshane:
1. Injongo ephambili Ngokomgangatho wesizwe we-GB 24540-2009 "Impahla ekhuselayo ye-acid-base yekhemikhali yokukhusela impahla", esi sixhobo sisebenzisa indlela yokuqhuba kunye nesixhobo sexesha elizenzekelayo ukuvavanya ixesha lokungena kwe-fat-base ye-laphu ye-acid-base yempahla yokukhusela yeekhemikhali.Isampuli ifakwe phakathi kweebhodi eziphezulu kunye nezantsi , Ucingo oluqhubayo luxhunywe kwibhodi ephezulu kwaye ludibanisa nomgangatho ophezulu wesampuli ngexesha elifanayo.Xa ukungena...
1. Injongo ephambili
Ngokomgangatho wesizwe we-GB 24540-2009 "Impahla ekhuselayo ye-acid-base yekhemikhali yokukhusela iimpahla", esi sixhobo sisebenzisa indlela yokuqhuba kunye nesixhobo sexesha elizenzekelayo ukuvavanya ixesha lokungena kwempahla ye-asidi-base yekhemikhali yokukhusela.Isampuli ifakwe phakathi kweebhodi eziphezulu kunye nezantsi , Ucingo oluqhubayo luxhunywe kwibhodi ephezulu kwaye ludibanisa nomgangatho ophezulu wesampuli ngexesha elifanayo.Xa kwenzeka into yokungena, isiphaluka sivuliwe, isibonakaliso sombane sithunyelwa ngaphandle, kwaye ixesha lirekhodwa.Ixesha elivela xa isisombululo sokuvavanya sichithwa kwisampuli ukuya xa umqondiso ubonakala ubizwa ngokuba lixesha lokungena kwisampuli.
2. Iimpawu eziphambili zobugcisa
