Kuphela kufuneka ujonge umaleko omnye, unokuhlangabezana nokumelana nokubola kwetape ye-weld

Tower isetyenziselwa distillation, ukuhlanjululwa, ukufunxa, distillation kunye nezinye izixhobo zemichiza, uninzi izixhobo inqaba kufuneka uqhagamshelane acid, alkali, ityuwa, izinyibilikisi eziphilayo kunye nezinye eendaba ezonakalisayo, ngoko ke kuyimfuneko ukuba phezu indawo enkulu yomaleko umhlwa. kwi-cylinder kunye neendawo zokutywina.Njengendlela esebenzayo yokujonga umphezulu, i-strip overfacing isetyenziswa kakhulu kwi-tower welding yezixhobo zekhemikhali.
Itekhnoloji ye-electrode yesiko yokujonga itekhnoloji yitekhnoloji ye-arc egqwethiweyo ephindwe kabini enomaleko wenguqu kunye nomaleko onganyangekiyo, kodwa le teknoloji inomjikelo omde wokwenza kunye neendleko eziphezulu zokwenziwa.Ukuze kusonjululwe le ngxaki, iJingQunCo iphuhlise izixhobo zokuwelda ezikumgangatho omnye (i-GDS-309LA intambo yokuwelda, i-GXS-ED308L i-electroslag flux), enokufikelela kwisiphumo sokuvela kwemigangatho emibini ngocweyo olulodwa kuphela, kwaye inokwenza lula. inkqubo yokujonga umphezulu ukusuka kwimigangatho emibini ukuya kumphezulu womaleko omnye.
