Kufotokozera: Iyi ndi electrode yapadera yokhala ndi hydrogen sodium yochepa yophimbidwa ndi chitsulo chopangidwa ndi aluminiyamu. Gwiritsani ntchito DCEP (electrode yamagetsi yolunjika), ndipo imatha kulumikizidwa m'malo onse ndi ntchito yochepa ya arc. J557SLA ikhoza kulumikizidwa mwachindunji popanda kuchotsa wosanjikiza wa aluminiyamu pamwamba pa groove musanawotchere. Koma J557SLB iyenera kuchotsa wosanjikiza wa aluminiyamu pamwamba pa groove musanawotchere.

Kugwiritsa Ntchito: Amagwiritsidwa ntchito polumikiza kapangidwe ka chitsulo chopangidwa ndi aluminiyamu pansi pa hydrogen sulfide, sulfure, ammonia, ammonium bicarbonate ndi hydrogen nitrogen ndi kutentha kogwira ntchito pansi pa 540°C. Monga mapaipi a boiler, zida zoyeretsera mafuta, zida za feteleza ndi mapaipi a nthunzi, ndi zina zotero.

 Kapangidwe ka mankhwala a chitsulo chosungunula (%):

 Kapangidwe ka makina a chitsulo chosungunula:

Kuchuluka kwa haidrojeni m'chitsulo chosungidwa: ≤6.0mL/100g (njira ya glycerin)

Kuwunika kwa X-ray: Giredi I

Mphamvu yovomerezeka:

Zindikirani:

1. Electrode iyenera kuphikidwa kwa ola limodzi pa kutentha kwa pafupifupi 350℃ isanayambe kuwotcherera;

2. Ndikofunikira kuyeretsa dzimbiri, mafuta oyeretsera, madzi, ndi zinyalala pa zipangizo zowotcherera musanawotchetse.
