(1) Qhov muaj pes tsawg leeg thiab qhov siab ntawm qhov nruab nrab: Lub zog ntawm cov concentration sib txawv. Piv txwv li, hauv hydrochloric acid, qhov siab dua qhov concentration, qhov hnyav dua qhov corrosion. Cov pa roj carbon steel thiab stainless hlau corrode qhov hnyav tshaj plaws nyob rau hauv sulfuric acid nrog ib tug concentration ntawm txog 50%, thiab thaum lub concentration nce mus rau ntau tshaj 60%, corrosion txo sharply;
(2) Cov impurities tsis zoo muaj xws li chloride ions, sulfur ions, cyanide ions, ammonia ions, thiab lwm yam, uas tuaj yeem ua rau muaj kev xeb loj heev;
(3) Kub: Corrosion yog tshuaj lom neeg cov tshuaj tiv thaiv, thiab rau txhua txhua 10 degree qhov kub thiab txias, tus nqi corrosion nce li ntawm 1-3 zaug, tab sis muaj kev zam;
(4) PH tus nqi: Feem ntau, tus nqi pH qis dua, qhov ntau dua qhov corrosion ntawm cov hlau;
(5) Flow rate: Feem ntau, qhov siab dua qhov ntws, qhov ntau dua qhov corrosion.
