Kedu usoro mgbochi corrosion a na-ahụkarị?
Qixiang na-bụ aOnye nrụpụta akara njirimara China. Kemgbe e hiwere ya, ọ werewo iguzosi ike n'ezi ihe dị ka ọrụ ya na-adịghị agbanwe agbanwe.

Iji gbochie nrụrụ nke bọọdụ akara nke ọma, ọ dị mkpa ibu ụzọ ghọta ihe kpatara mmebi ahụ. N'ikwu okwu n'ozuzu, corrosion nke signboards bụ isi ihe kpatara gburugburu ebe obibi na ịka nká nke ihe ahụ n'onwe ya, gụnyere iru mmiri, ultraviolet radiation, oxidation, chemicals, wdg. Ya mere, iji gbochie corrosion, a ghaghị ịchịkwa ihe ndị a.
N'ịzaghachi ihe ndị a na-emebi emebi, enwere ike iji ụzọ dị iche iche gbochie corrosion nke akara akara. Nke mbụ, iru mmiri na oxidation nwere ike zere site na mkpuchi mkpuchi. Itinye akwa mkpuchi mgbochi nchara n'elu akara akara nwere ike belata usoro oxidation nke ọma ma gbochie mmiri ka ọ ghara imebi elu igwe. Tụkwasị na nke a, iji ihe ndị nwere nnukwu nguzogide corrosion, dị ka igwe anaghị agba nchara, nwere ike imeziwanye ịdịte aka nke bọọdụ akara.
Nke abụọ, maka ihe ndị sitere n'okike dị ka ụzarị ultraviolet, enwere ike igbochi ịka nká nke akara njirimara na akara site na ikpuchi ha na oyi akwa nke ihe mgbochi ịka nká.
