Tlhaloso ea Sehlahisoa
Mehala ena ea ho hanyetsa enameled e 'nile ea sebelisoa ka bophara bakeng sa li-resistors tse tloaelehileng, koloi
likarolo, li-resistors tsa matsoelintsoeke, joalo-joalo ho sebelisa ts'ebetso ea ho kenya letsoho e loketseng lits'ebetso tsena, ho nka monyetla ka botlalo ba likarolo tse ikhethang tsa ho roala enamel.
Ho feta moo, re tla etsa insuela ea enamel ea terata ea tšepe ea bohlokoa joalo ka terata ea silevera le platinamo ka taelo. Ka kopo, sebelisa tlhahiso ena ka odara.
