1. Sulfuric acid A matsayin daya daga cikin kafofin watsa labaru mai karfi mai lalata, sulfuric acid shine muhimmin kayan masana'antu tare da amfani mai yawa. Lalacewar sulfuric acid tare da yawa daban-daban da yanayin zafi ya bambanta sosai. Don maida hankali sulfuric acid tare da maida hankali sama da 80% da zafin jiki kasa da 80 ℃, carbon karfe da simintin gyare-gyaren da kyau lalata juriya, amma shi bai dace da high-gudun gudãna sulfuric acid. Bai dace da amfani dashi azaman abu don bawul ɗin famfo ba; bakin karfe na yau da kullun kamar 304 (0Cr18Ni9) da 316 (0Cr18Ni12Mo2Ti) suna da iyakacin amfani ga kafofin watsa labarai na sulfuric acid. Don haka, bawul ɗin famfo don jigilar sulfuric acid yawanci ana yin su ne da ƙarfe mai ƙarfi na siliki (wanda ke da wuyar jefawa da sarrafawa) da babban ƙarfe mai ƙarfi (alloy 20). Fluoroplastics suna da mafi kyawun juriya ga sulfuric acid, kuma bawul ɗin da aka yi da fluorine shine zaɓi mafi tattalin arziki.
2. Acetic acid yana daya daga cikin abubuwa masu lalata a cikin kwayoyin acid. Karfe na yau da kullun zai lalace sosai a cikin acetic acid a kowane yanayi da yanayi. Bakin karfe kyakkyawan abu ne mai jurewa acetic acid. 316 bakin karfe mai dauke da molybdenum shima ya dace da yanayin zafi mai zafi da Dilute acetic acid tururi. Don buƙatun buƙatu kamar babban zafin jiki da babban taro na acetic acid ko ɗauke da wasu kafofin watsa labarai masu lalata, za'a iya zaɓar manyan bawul ɗin bakin karfe ko bawul ɗin fluoroplastic.
3. Hydrochloric acid Yawancin kayan ƙarfe ba su da juriya ga lalata hydrochloric acid (ciki har da kayan ƙarfe daban-daban), kuma babban silicon ferro-molybdenum za a iya amfani dashi kawai a cikin hydrochloric acid da ke ƙasa da 50 ° C da 30%. Sabanin kayan ƙarfe, yawancin kayan da ba na ƙarfe ba suna da kyakkyawan juriya ga hydrochloric acid, don haka bawul ɗin roba da bawul ɗin filastik (irin su polypropylene, fluoroplastics, da sauransu) sune mafi kyawun zaɓi don jigilar hydrochloric acid.
4. Nitric acid. Yawancin karafa suna saurin lalacewa a cikin nitric acid. Bakin karfe shine abu mafi jurewa nitric acid da aka fi amfani dashi. Yana da kyakkyawan juriya na lalatawa ga duk yawan adadin nitric acid a cikin zafin jiki. Yana da daraja ambaton cewa bakin karfe dauke da molybdenum (kamar The lalata juriya na 316, 316L) zuwa nitric acid ba kawai kasa da talakawa bakin karfe (kamar 304, 321), da kuma wani lokacin ma kasa. Don yawan zafin jiki na nitric acid, titanium da kayan gami na titanium yawanci ana amfani da su.
