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