Iindlela zokususa umhlwa kwiibheringi: Ukupholisha ngesandla kunye nokucoca ngamakhemikhali

 

Iibheringizizinto ezichanekileyo kwizixhobo zoomatshini. Umhlwa awuchaphazeli nje kuphela ukuchaneka kokusebenza kodwa unokukhawulezisa ukuguguleka. Ukubethela umhlwa ngokungaboniyo okanye ukunyanzela umhlwa kuya kubangela umonakalo ongakumbi. Iindlela zokulungisa zesayensi kufuneka zilungelelaniswe nemeko ethile: umhlwa omncinci uyacetyiswa ngonyango oluthambileyo lwesandla, ngelixa umhlwa omkhulu ufuna ukucocwa ngamakhemikhali anzulu. Ngezantsi kukho iindlela ezimbini ezisebenzayo nezisebenzayo zokususa umhlwa.

 

1. Ukupholisha ngesandla: Ukulungiswa ngobunono, Kufanelekile kwi-Rust yomphezulu

Xa kukho i-oxidation okanye amabala amancinci kuphela kwi-ibhereyithaUmphezulu, ukupolisha ngesandla kunokubuyisela ukugqitywa okugudileyo ngaphandle kokusebenzisa iikhemikhali eziqatha.

 

Ukupholisha kokuqala: Sebenzisa i-sandpaper encinci ye-000-grit okanye ilaphu le-emery elithambileyo ukuze uhlikihle ngokulinganayo indawo enomhlwa ecaleniibhereyithaindlela yokugijima, ukuphepha uxinzelelo olugqithisileyo olunokubangela imikrwelo.

 

Ukupholisha okuHleliweyo: Khetha i-compound yokupholisha ngokusekelwe kubukhali bomhlwa, isiya ikhula kancinci kancinci ukusuka ekubeni rhabaxa ukuya ekubeni ncinci. Kwi-rust enganzulu, i-compound yokupholisha egqityiweyo ingasetyenziswa ngokuthe ngqo.

 

Isalathiso sePaste ye-Abrasive eyenziwe ekhaya: Abasebenzisi abanamava banokuxuba i-chromium chloride, i-sodium silicate, kunye ne-stearic acid ngomlinganiselo ofanelekileyo ukwenza indawo yokupholisha esebenza kakuhle ukuze kuphuculwe iziphumo zokupholisha. Le ndlela inika iingenelo zokulawula kwaye ayonakalisi i-substrate, nto leyo eyenza ukuba ifaneleke ngakumbi ukugcinwa kweebheringi ezichanekileyo okanye izinto ezincinci.

 

 

2. Ukunyibilika kweekhemikhali: Ukususwa okunamandla komhlwa ngenxa yokubola okunzulu

 

Xa umaleko womhlwa utyebile okanye unemingxuma, ukupholisha ngokwasemzimbeni akusebenzanga kakuhle kwaye kunzima ukuwususa ngokupheleleyo. Ukususwa komhlwa ngamakhemikhali kufuneka kusetyenziswe ukususa ngokukhawuleza i-oxide ngokusebenzisa isisombululo.

 

Inkqubo Eqhelekileyo Yokusebenza:

 

Ukucoca kwangaphambili: Kususa ioyile kunye nokungcola ukuqinisekisa ukudibana okusebenzayo phakathi kwesisombululo seekhemikhali esilandelayo kunye nomphezulu wesinyithi;

 

Ukuhlamba ngamanzi ashushu: Kunyusa ubushushu bezinto zokusebenza ukuze kube lula ukusebenza ngokulinganayo kwe-asidi;

 

I-Pickling Soak: Isebenzisa isisombululo sokususa umhlwa esiqulathe i-chromic anhydride, i-phosphoric acid, okanye i-sulfuric acid, kunye nezithinteli zokubola ezongeziweyo ukukhusela isiseko sesinyithi;

 

Ulawulo lobushushu: Ifudumeza isisombululo se-pickling ukuya kuma-60–95°C (kuxhomekeke kwifomyula) ukuze inyuse kakhulu izinga lokusabela;

 

Emva konyango: Emva kokucwiliswa, kuhlanjwa ngamanzi abandayo, kuncitshiswe i-alkaline, kufakwe i-passivation yokuthintela ukugqwala, kwaye kutywinwe ioyile okokugqibela ukuze kuthintelwe i-oxidation yesibini.

 

Iingcebiso zoKhuseleko: Ulwelo oluneasidi ludla ngokugqwala kakhulu. Nxiba izixhobo zokuzikhusela rhoqo xa uphatha kwaye usebenza kwindawo enomoya ococekileyo. Amanzi amdaka kufuneka asuswe ngokwemigaqo kwaye akufuneki alahlwe ngokungakhathali.

 

Nokuba ufuna ukugqiba ukupholisha ngesandla okuthambileyo okanye ukucoca ngeekhemikhali ngokufanelekileyo, isitshixo sisekusebenziseni isisombululo esifanelekileyo kwimeko efanelekileyo. Ukwazi ukukhetha izixhobo ngokuchanekileyo, ulandelelwano lwenkqubo, kunye neenkqubo zokhuseleko akuyi kwandisa ubomi bebhereyitha kuphela kodwa kuya kuqinisekisa ukusebenza kwezixhobo okugudileyo nokuthembekileyo. Ekugcinweni kwemihla ngemihla, kuyacetyiswa ukuba kubekwe phambili iindlela ezingangenisi kakhulu kwaye kusetyenziswe kuphela iindlela zeekhemikhali xa kuyimfuneko ukufezekisa iinjongo ezimbini zokubuyisela ukusebenza kunye nokukhusela izinto.
