Apickling usoro na usoro nke ziri ezi enweghị nkebi ígwè anwụrụ

1. Nkenke enweghị nkebi ígwè anwụrụ pickling usoro

Nkenke enweghị nkebi nchara anwụrụ pickling usoro tumadi na-agụnye impregnated acid ịsacha usoro, ịgba acid ịsacha usoro na acid mado nchara mwepụ usoro.Generally, anyị na-eji impregnated acid saa usoro, na ịgba usoro nwere ike ji mee ihe na uka production.Steel akụkụ na-n'ozuzu pickling. na 10% ~ 20% (olu) sulfuric acid ngwọta na okpomọkụ nke 40 C. Mgbe ngwọta nke ígwè ọdịnaya karịrị 80g / L na ferrous sulfate gafere 215g / L, a ga-edochi ude mmiri acid. N'ime ụlọ okpomọkụ, na 20 % ~ 80% (olu) nke hydrochloric acid ngwọta maka ígwè pickling, adịghị mfe ime corrosion na hydrogen kenkuwa phenomenon.Due ka oké corrosive mmetụta nke acid na metal, corrosion inhibitor na-agbakwunyere.Mgbe ihicha, metal elu na-aghọ ọlaọcha ọcha. , na passivate elu ka mma corrosion iguzogide nke igwe anaghị agba nchara.

Iji kpochapụ mgbasa ozi elu ma belata chromatographic peak drag ọdụ, a ga-agwọ onye na-ebu ya na mmiri acid ma ọ bụ alkali na-asachapụ tupu ejiri ya. , nzacha, na-asachapụ na-anọpụ iche, na akpọnwụwo.Acid ịsacha nwere ike wepụ ígwè, aluminum, calcium, magnesium na ndị ọzọ adịghị ọcha na tebụl, ma enweghị ike wepụ silicone mmanya otu. Onye pickling kwesịrị ekwesị maka nyochaa acidic samples.

2.The mmetụta nke kpọmkwem enweghị nkebi ígwè anwụrụ pickling

Wepu mmanụ na nchara nke nkenke enweghị nkebi nchara nchara iji kwadebe maka usoro ọzọ. Na usoro mmepụta, usoro pickling bụ iwepụ akpụkpọ ahụ oxidation n'elu, mgbe ọgwụgwọ lubrication gasịrị (carbon steel-phosphorus saponification, igwe anaghị agba nchara-butter wayo, ọla kọpa aluminum pipe). -mmanụ), na usoro ochie-ọla kọpa), na mgbe ahụ mmịpụta na nhazi miri emi. Ọ bụrụ na ọkpọkọ ígwè anaghị amịpụta, enwere ike inwe oxide na mmanụ n'elu.Mmetọ, phosphoride mmiri mmiri nuklia ike enweghị ike iwepu ha, phosphoride àgwà ga-ebelata.
