TLHALOSO:
PA-8016-B8 ke eleketrode e tlase ea haedrojene eo tšepe ea weld e nang le 9% Cr-1% Mo.E etselitsoe tšepe ea mocheso o phahameng le litšepe bakeng sa lits'ebeletso tse chesang tsa hydrogen, haholo indastering ea petrochemical.Electrode e ka amoheloa ka lebaka la matla a eona a phahameng a ho tsitsa, ho tiea ho hotle le ho hanyetsa mocheso o moholo.
LINTLHA TSA HO SEBELISA:
1. Omisa li-electrode ho 350-400 ° C hoo e ka bang hora e le 'ngoe pele u sebelisoa' me u boloke li-electrode ho 100-150 ° C ka mor'a ho omisa ka hloko ho qoba mongobo.
2. Amohela mokhoa oa ho khutlela morao kapa otla arc holim'a poleiti e nyane ea tšepe e lokiselitsoeng morero ona ho thibela li-blowholes ho arc ho qala.
3. Boloka arc e khutšoanyane kamoo ho ka khonehang.
4. Preheat ka 100-150 ° C.Thempereichara e lokelang ho sebelisoa e fapana ho latela botenya ba poleiti le mofuta oa tšepe e lokelang ho chesetsoa.
5. Ela hloko hore u se ke ua feta mocheso o nepahetseng oa mocheso hobane mocheso o feteletseng o kenya letsoho o baka ho senyeha ha litekanyetso le ho hlahisa matla a tšepe ea weld.
