1. Sulfuric acid Sida mid ka mid ah warbaahinta xoogga leh, sulfuric acid waa walxo ceeriin oo warshadeed oo muhiim ah oo leh tiro aad u ballaaran oo la isticmaalo. Daxalka sulfuric acid oo leh heerkul kala duwan iyo heerkulku aad ayuu u kala duwan yahay. Sulfuric acid ee la ururiyey oo leh uruurin ka sarreeya 80% iyo heerkul ka yar 80 ℃, birta kaarboonka iyo birta tuurtu waxay leeyihiin iska caabin daxaleed oo wanaagsan, laakiin kuma habboona sulfuric acid socodka xawaaraha sare leh. Kuma haboona in loo isticmaalo sida walxo bamka; biraha caadiga ah sida 304 (0Cr18Ni9) iyo 316 (0Cr18Ni12Mo2Ti) ayaa xadiday isticmaalka warbaahinta sulfuric acid. Sidaa darteed, bambooyinka lagu qaado sulfuric acid waxaa inta badan laga sameeyaa bir shub ah oo silikon sare leh (ay adag tahay in la shubo iyo habsocodsiinta) iyo birta-daawaha sare (daawaha 20). Fluoroplastics waxay leeyihiin iska caabin wanaagsan oo aysiidh sulfuric ah, iyo valves-ka leh fluorine ayaa ah doorasho dhaqaale badan.
2. Aashitada loo yaqaan 'Acetic acid' waa mid ka mid ah walxaha ugu wasakhaysan asiidhka organic. Birta caadiga ah waxay si ba'an ugu daxaloobaysaa aashitada acetic dhammaan xajmiyada iyo heerkulka. Birta aan lahayni waa wax aad u fiican oo u adkaysta aashitada. 316 bir ah oo ka kooban molybdenum sidoo kale waxay ku haboon tahay heerkulka sare iyo uumiga acetic acid. Shuruudaha loo baahan yahay sida heerkul sare iyo fiirsashada sare ee acetic acid ama ay ku jiraan warbaahinta kale ee daxalaysa, alwaaxyada birta aan daxalka lahayn ee Alloy-ka sare ama valves fluoroplastic ayaa la dooran karaa.
3. Hydrochloric acid Inta badan walxaha birta ah uma adkeysanayaan daxalka aashitada hydrochloric (oo ay ku jiraan walxo kala duwan oo bir ah), iyo ferro-molybdenum-silicon-sare waxaa loo isticmaali karaa oo kaliya hydrochloric acid ee ka hooseeya 50 ° C iyo 30%. Ka soo horjeeda walxaha birta ah, inta badan walxaha aan biraha ahayn waxay leeyihiin iska caabin wanaagsan oo u adkaysta hydrochloric acid, sidaas darteed caagadaha caagga ah iyo caagagga caagga ah (sida polypropylene, fluoroplastics, iwm.) ayaa ah doorashada ugu fiican ee qaadista hydrochloric acid.
4. Nitric acid. Inta badan biraha ayaa si degdeg ah ugu daxaloobay nitric acid. Birta aan-dhalatada lahayn waa shayga ugu badan ee loo isticmaalo nitric acid. Waxay leedahay iska caabin wanaagsan oo daxalka ah oo dhan dhammaan uruurinta nitric acid heerkulka qolka. Waxaa mudan in la xuso in birta aan nadiifka ahayn ee ay ku jirto molybdenum (sida iska caabbinta daxalka ee 316, 316L) ee nitric acid ma aha oo kaliya ka hooseeya birta caadiga ah (sida 304, 321), iyo mararka qaarkood xitaa ka hooseeya. Heerkulka sare ee nitric acid, titanium iyo titanium alloy alaabta ayaa badanaa la isticmaalaa.
