1. Sulfuric acid Seimwe yemagetsi akasimba anoodza, sulfuric acid yakakosha maindasitiri emafuta ane huwandu hwakawanda hwekushandisa. Kuora kwe sulfuric acid ine huwandu hwakasiyana uye tembiricha zvakasiyana. Kune concentrated sulfuric acid ine concentration pamusoro pe80% uye tembiricha isingasviki 80 ℃, carbon steel necast iron zvine good corrosion resistance, asi haikodzere high-speed kuyerera sulfuric acid. Hazvina kukodzera kushandiswa sechinhu chepombi valves; simbi dzakajairwa dzisina tsvina dzakadai se304 (0Cr18Ni9) uye 316 (0Cr18Ni12Mo2Ti) dzine mashoma ekushandisa sulfuric acid media. Nokudaro, mavharuvhu epombi ekutakura sulfuric acid anowanzogadzirwa ne-high-silicon cast iron (yakaoma kukanda nekugadzirisa) uye yakakwirira-alloy simbi isina tsvina (alloy 20). Fluoroplastics ine kuramba iri nani kune sulfuric acid, uye mavharuvhu ane fluorine-aned isarudzo ine hupfumi.
2. Acetic acid ndechimwe chezvinhu zvinopisa zvakanyanya muorganic acids. Simbi yakajairika ichave yakasvibiswa zvakanyanya muacetic acid pane zvese zvakadzika uye tembiricha. Simbi isina tsvina yakanakisa acetic acid inodzivirira zvinhu. 316 simbi isina tsvina ine molybdenum inokodzerawo kupisa kwakanyanya uye Dilute acetic acid mhute. Nekuda kwezvinodiwa senge tembiricha yakakwira uye yakanyanya kuwanda kweacetic acid kana iine imwe corrosive media, yakakwirira alloy Stainless simbi mavharuvhu kana fluoroplastic mavharuvhu anogona kusarudzwa.
3. Hydrochloric acid Zvizhinji zvesimbi zvinhu hazvigadziriswi nehydrochloric acid corrosion (kusanganisira zvakasiyana-siyana zvesimbi isina tsvina), uye yakakwirira-silicon ferro-molybdenum inogona kushandiswa chete muhydrochloric acid pasi pe50 ° C uye 30%. Kusiyana nemidziyo yesimbi, zvinhu zvakawanda zvisiri zvesimbi zvine kunaka kwekusagadzikana kwehydrochloric acid, saka mavharuvhu erabha nemavharuvhu epurasitiki (senge polypropylene, fluoroplastics, nezvimwewo) ndiyo sarudzo yakanaka yekutakura hydrochloric acid.
4. Nitric acid. Masimbi mazhinji anokurumidza kuodzwa mu nitric acid. Stainless simbi ndiyo inonyanya kushandiswa nitric acid inodzivirira zvinhu. Iyo ine yakanaka corrosion resistance kune ese maconcentrations e nitric acid patembiricha yemumba. Zvakakosha kutaura kuti simbi isina tsvina ine molybdenum (yakadai seThe corrosion resistance of 316, 316L) kune nitric acid haisi yakaderera kune yakajairwa simbi isina tsvina (yakadai se304, 321), uye dzimwe nguva kunyange yakaderera. Pakupisa kwepamusoro nitric acid, titanium uye titanium alloy zvinhu zvinowanzo shandiswa.
