Ishishini leprofayili ye-aluminium yemizi-mveliso laseChongqing liphuhlile ngokukhawuleza kwiminyaka yakutshanje, kwaye liye lajongana kancinci kancinci nelizwe liphela. Itekhnoloji ye-anodizing yenye yeendlela ezisetyenziswa kakhulu kwishishini leprofayili ye-aluminium yemizi-mveliso laseChongqing. Abasebenzisi abaninzi abatsha abazi nto ingako malunga nenkqubo ye-anodizing, ngoko makhe sikunike intshayelelo eneenkcukacha.
Ukuhamba kwenkqubo yonyango lwe-oxidation kwiiprofayili ze-aluminium zoshishino eChongqing;
1. Unyango lomphezulu.
Unyango lomphezulu, okwaziwa ngokuba lunyango lwangaphambi komphezulu, kukususa ukungcola kumphezulu weprofayili ye-aluminiyam ngokusebenzisa izinto ezibonakalayo kunye neekhemikhali, ukuze ikwazi ukuvezwa emzimbeni weprofayili ye-aluminiyam, nto leyo elula ukunyanga i-oxidation kumphezulu weprofayili ye-aluminiyam kwinqanaba lokugqibela.
2. Inkqubo yokususa amafutha kumphezulu.
Injongo yenkqubo yokususa amafutha kukususa ii-lubricants zoshishino, ioyile ethintela ukubola kunye nokungcola kokungcola okunamathele kumphezulu weprofayili ye-aluminiyam, ukuqinisekisa ukubola kwe-alkali efanayo kwiprofayili ye-aluminiyam kunye nokucoceka kwetanki yokubola kwe-alkali. Ukuphucula umgangatho wonyango lomphezulu weprofayili ye-aluminiyam.
3. Inkqubo yokugrumba iasidi.
Inkqubo yokugrumba i-asidi yomphezulu kukwenza unyango lokugrumba i-asidi yomphezulu emva kokususa i-aluminiyam profile, kwaye injongo ephambili yokususa kukususa i-oxide eyenziwe yi-oxidation yezinye izinto zesinyithi kumphezulu weprofayili ye-aluminiyam kunye nefilimu ye-oxide eyenziwe ngokwemvelo yiprofayili; Emva kokunyangwa kwe-asidi yomphezulu, kuyimfuneko ukuyihlamba ngoko nangoko, kwaye ubushushu bokuhlamba kufuneka bulawulwe ngama-50℃ kwangethuba ukuze kuthintelwe amabala okuhamba komphezulu weprofayili, uze uyicoce ngamanzi abalekayo. Ngenxa yokuba iprofayili ye-aluminiyam ine-copper, umphezulu uba mnyama emva kovavanyo lwe-asidi yomphezulu, kwaye kufuneka ufakwe kwisisombululo se-nitric acid imizuzu emi-3-5 ukuze wenze umphezulu ube yisilivere ekhazimlayo.
4. Inkqubo yokukrola i-alkaline.
Injongo ephambili yenkqubo yokugrumba i-alkali kukususa izinto eziseleyo kunye neengqimba eziguqulweyo kumphezulu weprofayili ye-aluminiyam ngexesha lokugrumba, kunye nokususa iziphene zokukrwela ezishiyekileyo kumphezulu weprofayili ye-aluminiyam ngexesha lokuxova. Unyango lokugrumba i-alkaline kumphezulu weprofayili ye-aluminiyam ludlala indima ebalulekileyo kumgangatho opheleleyo womphezulu weprofayili ye-aluminiyam.
5. Inkqubo yokungathathi cala.
Injongo yenkqubo yokunganyibiliki kukususa izinto ze-alloy okanye ukungcola okufana nobhedu, i-manganese, isinyithi, i-silicon, njl.njl. ezinganyibiliki kwisisombululo se-alkaline esishiywe kumphezulu weprofayili ye-aluminium emva kokugrumba kwe-asidi kunye nokugrumba kwe-alkali. Ngokubanzi, indlela yokunganyibiliki kwesisombululo se-alkaline esishiywe kwiprofayili ye-aluminium emva kokugrumba kwe-alkali kukusebenzisa isisombululo se-nitric acid esingama-30%-50%. Kwi-alloy ye-aluminium ene-silicon ephezulu, kukhethwa i-asidi exutyiweyo ye-nitric acid kunye ne-hydrogen fluoride enomlinganiselo wevolumu we-1: 3. I-Silicon isabela kunye ne-hydrogen kunye ne-hydrofluoric acid ukuvelisa i-fluosilicic acid, eshiya umphezulu we-aluminium.
6. Unyango lwe-anodizing.
Indlela yonyango lwe-anodic oxidation kukuba isisombululo sisetyenziswe njengesixhobo, kwaye ukukhutshwa kwencam kukhethwa ukwenza ifilimu ye-oxide kumphezulu weprofayili ye-aluminium, ukuze iprofayili ye-aluminium ibe nokumelana nokugqwala okuphezulu. Ngenxa yokuba umaleko okhuselayo ofunyenwe yi-anodic oxidation yeprofayili ye-aluminium unobunzima obuphezulu kunye nokumelana nokugqwala, ubukhulu obuqhelekileyo yi-10-12μ m, nto leyo enokuphucula ngcono ukumelana nokugqwala kweprofayili ye-aluminium kunye nobuhle beprofayili ye-aluminium.
Inkqubo ye-anodic oxidation idlala indima ebalulekileyo kubuhle kunye nokuqina kweeprofayili ze-aluminium zezimboni zaseChongqing.
