Ukukha
Ngokutsho koxinzelelo oluthile, ubushushu kunye nesantya, iiasidi zisetyenziselwa ukususa ulusu lwe-iron oxide ngemichiza, ebizwa ngokuba yi-pickling.
I-Phosphating:
Inkqubo yokwenza i-phosphate ukutyabeka kumphezulu wesinyithi ngokusebenzisa iikhemikhali kunye neempendulo ze-electrochemical.Ifilimu yokuguqula i-phosphate ebizwa ngokuba yifilimu ye-phosphating.
Injongo: Ukuphucula i-anti-corrosion kunye ne-anti-rust properties kumphezulu wezinto eziphathekayo.Ngexesha elifanayo, ifilimu ye-phosphate eyenziwe njenge-lubricating carrier ine-reaction efanelekileyo kunye ne-lubricant kwaye iyanciphisa i-coefficient ye-friction surface ye-procession elandelayo yezinto.Ukuphucula ukunamathela kwepeyinti kwaye ulungiselele inyathelo elilandelayo.
Saponification:
Emva kokuba i-workpiece i-phosphating, i-stearate kunye ne-zinc phosphate ifilimu umaleko kwisisombululo esintywiliselwe kwi-saponification bath isabela ukwenza i-zinc stearate saponification layer.Injongo: Ukwenza umaleko we-saponification kunye ne-adsorption egqwesileyo kunye ne-lubricity kumphezulu wezinto eziphathekayo, ukwenzela ukuba kube lula inkqubela phambili egudileyo yeteknoloji yokucubungula elandelayo.
Indlela ye-pickling rust kunye nesikali yindlela esetyenziswa kakhulu kwintsimi yezoshishino.Injongo yokususa i-rust kunye ne-oxide scale ifezekiswa ngumatshini wokuhlutha i-asidi kwi-oxide ye-dissolution kunye ne-corrosion ukuvelisa igesi ye-hydrogen.Ezona zixhaphakileyo zisetyenziswa ekuchongeni yi-hydrochloric acid, i-sulfuric acid, kunye ne-phosphoric acid.Iasidi yenitric ayifane isetyenziswe kuba ivelisa igesi yenitrogen dioxide eyityhefu ngexesha lokuchola.I-Hydrochloric acid pickling ilungele ukusetyenziswa kumaqondo aphantsi, akufanele idlule i-45 ℃, kufuneka idibanise isixa esifanelekileyo se-acid inhibitor.Isantya sokuchola i-sulfuric acid kwiqondo lobushushu eliphantsi sicotha kakhulu, sifanelekile ukusebenzisa kwiqondo lobushushu eliphakathi, iqondo lobushushu 50 – 80 ℃, sebenzisa i-concentration ye-10% – 25%.I-advanteji ye-phosphoric acid pickling kukuba ayiyi kuvelisa iintsalela ezidliwayo, ezikhuselekileyo, kodwa ukungahambi kakuhle kwe-asidi ye-phosphoric yindleko ephezulu, isantya esicothayo sokuchola, ukusetyenziswa ngokubanzi kwe-10% ukuya kwi-40%, kunye nobushushu bokucubungula ubushushu obuqhelekileyo ukuya kuma-80 ℃.Kwinkqubo yokuchola, ukusetyenziswa kwe-acids edibeneyo kuyindlela esebenzayo kakhulu, njenge-hydrochloric acid-sulfuric acid exutywe ne-asidi, i-phosphoric acid-citric acid exutywe.
Umgca wokukhetha owenziwe nguWuxi T-control uvalelwe ngokupheleleyo kwaye uzenzekelayo.Inkqubo yokuvelisa iqhutyelwa kwitanki evaliweyo kwaye ihlukaniswe nehlabathi langaphandle;inkungu ye-asidi eveliswayo ikhutshwa yinqaba yenkungu ye-asidi yonyango lokucoca;inkqubo yokuvelisa yodwa kwimpilo ye-Impact yomsebenzisi;ulawulo oluzenzekelayo, ukusebenza kakuhle kwemveliso, imveliso enkulu, ilungele imveliso enkulu, imveliso esembindini;ulawulo oluzenzekelayo lwekhompyutha yeeparamitha zenkqubo, inkqubo yokuvelisa ezinzileyo;xa kuthelekiswa nomgca wokuvelisa we-phosphating wangaphambili, kuphuculwe kakhulu ukusebenza, kodwa kwakhona ngokugqithisileyo Umhlaba unciphisa ukungcoliseka kwendalo.
