Kungofunika kungoyang'ana wosanjikiza umodzi, kumatha kuthana ndi kukana kwa dzimbiri kwa tepi yowotcherera

Tower ntchito distillation, kuyeretsedwa, mayamwidwe, distillation ndi zida zina mankhwala, ambiri mwa zipangizo nsanja ayenera kukhudzana ndi asidi, zamchere, mchere, zosungunulira organic ndi zina zikuwononga TV, choncho m'pofunika surfacing dera lalikulu la dzimbiri zosagwira wosanjikiza. m'zigawo za silinda ndi zosindikizira. Monga njira yabwino yopangira pamwamba, kuyika mizere kumagwiritsidwa ntchito kwambiri pakuwotcherera nsanja kwa zida zama mankhwala.
Ukadaulo wapachikhalidwe wa electrode sufacing ndiukadaulo wapawiri wosanjikiza wa arc wokhala ndi wosanjikiza wosinthika komanso wosanjikiza ndi dzimbiri, koma ukadaulo uwu umakhala ndi nthawi yayitali yopangira komanso mtengo wokwera kwambiri. Pofuna kuthana ndi vutoli, JingQunCo yapanga zida zowotcherera zosanjikiza imodzi (GDS-309LA, GXS-ED308L electroslag flux), zomwe zimatha kukwaniritsa kusanjika kwa magawo awiri ndi kungoyang'ana kosanjikiza kamodzi kokha, ndipo kumatha kukhala kosavuta. njira yoyang'ana kuchokera pansanjika ziwiri kupita kumtunda umodzi.
