Ukwaziswa kwe-Acid Pickling kunye ne-Passivation
Imibhobho yentsimbi isetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yokuqina kwayo okugqwesileyo, ukomelela, kunye nokunganyangeki komhlwa.Nangona kunjalo, ukuqinisekisa ukusebenza kwabo ngokugqibeleleyo kunye nokuphila ixesha elide, kubalulekile ukuphumeza iindlela zonyango ezisebenzayo ezifana nokunyuswa kwentsimbi kunye nokugqithisa.Le blog ijolise ekukhanyeni ukubaluleka kwezi nkqubo ekuphuculeni umgangatho kunye nokuqina kwemibhobho yentsimbi.
Icandelo 1: Yintoni ukuPickling yentsimbi?
I-Steel pickling yinkqubo yeekhemikhali ebandakanya ukukhutshwa kwezinto ezingcolileyo, ezifana ne-rust, scale, kunye ne-oxides, ukusuka kumphezulu wemibhobho yensimbi.Injongo ephambili ye-pickling kukucoca i-metal surface ngokucokisekileyo, ukuyilungiselela unyango olulandelayo olufana ne-passivation.
Ngethuba lenkqubo yokukhetha, iipayipi zensimbi zicwiliswa kwisisombululo esine-acidic, ngokuqhelekileyo siqukethe i-hydrochloric okanye i-sulfuric acid.I-asidi iphendula kunye nokungcola, ukuchithwa kunye nokuwasusa kwintsimbi yentsimbi, ukushiya ukugqiba okucocekileyo kunye nokugudileyo.
Icandelo lesi-2: Inkqubo yokuPickling:
Inkqubo yokukhetha ibandakanya amanyathelo amaninzi okuqinisekisa ukususwa okusebenzayo kokungcola kwimibhobho yentsimbi:
Inyathelo 1: Ukunciphisa: Phambi kokuchola, imibhobho yentsimbi iyacolwa ukuze kususwe nayiphi na ioyile, igrisi, okanye ubumdaka obukhoyo kumphezulu.Eli nyathelo liqinisekisa ukuba i-asidi inokusebenzisana ngokuthe ngqo kunye nokungcola kwindawo yesinyithi.
Inyathelo lesi-2: Ukuntywiliselwa kwe-Acid: Imibhobho eyohliweyo iye intywiliselwe kwisisombululo seasidi esikhayo.Ubude bexesha lokuntywiliselwa kuxhomekeke kwizinto ezifana nodidi kunye nobukhulu bomaleko we-oxide.Ngexesha lokuntywiliselwa, kubalulekile ukubeka iliso kwiqondo lobushushu kunye nokuxinana kweasidi ukufezekisa iziphumo ezifunwayo.
Inyathelo lesi-3: I-Acid Rinse: Emva kwenkqubo yokukha, imibhobho ihlanjululwa kakuhle ngamanzi ukususa nayiphi na i-asidi eseleyo.Eli nyathelo libalulekile ekuthinteleni nakuphi na ukusabela kweekhemikhali okunokuthi kwenzeke ngexesha lonyango lwangaphezulu olulandelayo.
Icandelo lesi-3: Ukubaluleka kokuPickling kwentsimbi:
Inkqubo yokuchola intsimbi ibonelela ngeenzuzo ezininzi kwimibhobho yentsimbi:
1. Umhlwa kunye nokususwa kwesikali: Ukuvuthwa kususa ngokufanelekileyo umhlwa kunye nesikali kumphezulu wentsimbi.Oku kungcola kunokuphazamisa ingqibelelo kunye nokubonakala kwemibhobho, okukhokelela ekugqokeni kwangaphambili kunye nokungaphumeleli kwesakhiwo.
2. Ukuphuculwa kwe-Corrosion Resistance: Ngokususa ukungcola, i-pickling idala indawo ecocekileyo kunye ne-oxide, ephucula ukuxhathisa kwentsimbi kwi-corrosion.Oku kubaluleke ngakumbi kwimibhobho esetyenziswa kwindawo erhabaxa okanye evezwe kwiikhemikhali kunye nokufuma.
3. I-Adhesion eyandisiweyo: I-Pickling ilungiselela umgangatho wentsimbi ngokudala i-texture erhabaxa, evumela ukuba ii-coatings ezilandelayo okanye unyango lubambelele ngokufanelekileyo.Oku kuqinisekisa ukunamathela okungcono kwepeyinti yokukhusela okanye iingubo, ezincedisa ukuhlala ixesha elide lemibhobho yensimbi.
Icandelo lesi-4: Ukuqonda iPasivation:
Emva kokukhetha, imibhobho yensimbi ingena kwinkqubo yokudlula ukwenza i-oxide ekhuselayo kwindawo.Oku kufezekiswa ngokuntywiliselwa imibhobho kwi-agent edlulayo, ngokuqhelekileyo isisombululo esihlanjululweyo se-nitric acid.
I-Passivation yenza ifilimu encinci, ecacileyo ye-chromium oxide kumphezulu wentsimbi, osebenza njengomqobo ngokuchasene nokubola.Lo maleko ukwanceda ekugcineni isibheno sobuhle bentsimbi ngelixa unciphisa umngcipheko wokubola okanye ukuguquka kombala.
ICandelo lesi-5: IiNzuzo zokuPasa:
I-Passivation ibonelela ngeenzuzo ezininzi eziphambili kwimibhobho yentsimbi:
1. I-Corrosion Resistance: Ukuqulunqwa komgangatho okhuselekileyo we-oxide ngokusebenzisa i-passivation kwandisa kakhulu ukuxhatshazwa kwentsimbi, ukuqinisekisa ixesha elide lokuphila kunye nokunciphisa iimfuno zokugcina.
2. Isibheno sobuhle: I-Passivation inceda ukugcina inkangeleko yembonakalo yemibhobho yentsimbi ngokunciphisa amathuba okuba namabala angaphezulu, ukuguquka kombala, okanye amabala erusi.Oku kubaluleke kakhulu kwimibhobho esetyenziswa kwizakhiwo okanye kwizinto zokuhombisa.
3. Impilo kunye noKhuseleko: I-passivation idala indawo engasebenziyo yeekhemikhali, ukunciphisa umngcipheko wokukhupha isinyithi okanye ukungcola, ngokukodwa kwimibhobho esetyenziselwa ukuhambisa amanzi okusela okanye iimveliso zokutya.
Isiphelo:
Ukuqukumbela, ukunyuswa kwentsimbi kunye nokupasa ngamanyathelo abalulekileyo kwiinkqubo zonyango lomphezulu wemibhobho yentsimbi.Ukususwa okusebenzayo kokungcola ngokukhethwa, okulandelwa kukubunjwa kwe-oxide ekhuselayo kwi-passivation, kwandisa kakhulu ukuqina, ukuxhathisa ukubola, kunye nesibheno sobuhle bemibhobho yensimbi.Ngokuqonda ukubaluleka kwezi nkqubo, amashishini anokuqinisekisa ixesha elide kunye nokuthembeka kweepayipi zensimbi kwizicelo ezahlukeneyo, ekugqibeleni zikhokelela ekusebenzeni okuphuculweyo kunye nokwaneliseka kwabathengi.
