n amafutha avikelayo ku-transformer angase ahlangane nomoya ngezikhathi ezithile. Kungaba ngesikhathi sokuvula noma yikuphi ukuvala noma ngenxa yokuvuza emathangeni kawoyela noma emigqeni yamapayipi ahlobene. Ngenxa yalokho ukusabela kwe-oxidation kuwoyela we-transformer kwenzeka, okuqhubeka kusheshiswa ngenxa yezinga lokushisa kanye nokuba khona kwama-catalysts njengensimbi, ithusi kanye nezinhlanganisela zensimbi ezincibilikisiwe kuwoyela we-transformer.

Ithuluzi likhipha i-asidi encibilikayo emanzini ne-alkali kusampula kusetshenziswa amanzi acwebile noma isixazululo se-ethanol. Bese uhlola
ukushintsha kombala we-solvent ekhishiwe nge-methyl orange noma inkomba ye-phenolphthalein ngokulandelanayo, noma unqume inani le-pH lesincibilikis esikhishiwe kusetshenziswa imitha ye-asidi ukuze kuqinisekiswe ukuthi ingabe ikhona yini i-asidi encibilikayo ne-alkali kusinyibiliki esikhishiwe.

Umshini wethu unenzuzo engezansi:
¯ Idizayini elula nezimfuneko zokuhlangabezana ze-GB/T 259.
¯ Amandla okushisa angalungiswa ngokuqhubekayo. Kulula ukulawula.
¯ Kulula ukusebenza. Umphumela unembile.
