Izindlela Zokususa Ukugqwala: Ukupholisha Ngesandla Nokuhlanza Amakhemikhali

 

Amabheringikuyizingxenye ezinembile emishinini yemishini. Ukugqwala akugcini nje ngokuthinta ukunemba kokusebenza kodwa kungasheshisa nokuguguleka. Ukushaywa ngesando noma ukuphoqa ukugqwala kungabangela umonakalo owengeziwe. Izindlela zesayensi zokulungisa kufanele zilungiselelwe isimo esithile: ukugqwala okuncane kunconywa ngokwelashwa okubucayi ngesandla, kuyilapho ukugqwala okukhulu kudinga ukuhlanzwa kwamakhemikhali ajulile. Ngezansi kunezindlela ezimbili ezisebenzayo nezisebenzayo zokususa ukugqwala.

 

1. Ukupholisha Ngesandla: Ukulungiswa Okuthambile, Kufanelekela Ukugqwala Komphezulu

Uma kukhona ukubola okuncane noma amabala kuphela ku-oxidation noma amabala ku-ibhereubuso, ukupholisha ngesandla kungabuyisela isiphetho esibushelelezi ngaphandle kokusebenzisa amakhemikhali anamandla.

 

Ukupholisha kokuqala: Sebenzisa i-sandpaper encane engu-000-grit noma indwangu ethambile ye-emery ukuze uhlikihle ngokulinganayo indawo egqwalile eduzeibhereumjaho, ukugwema ukucindezela okukhulu okungase kubangele imihuzuko.

 

Ukupholisha Okulinganisiwe: Khetha inhlanganisela yokupholisha ngokusekelwe ebunzimeni bokugqwala, kancane kancane ithuthuka kusukela kokukhuluphele kuya kokuncane. Ngokugqwala okungajulile, inhlanganisela yokupholisha eqediwe ingasetshenziswa ngqo.

 

Ireferensi Ye-Abrasive Paste Eyenziwe Ekhaya: Abasebenzisi abanolwazi bangaxuba i-chromium chloride, i-sodium silicate, kanye ne-stearic acid ngezilinganiso ezifanele ukudala indawo yokupholisha ephumelela kakhulu ukuze kuthuthukiswe imiphumela yokupholisha. Le ndlela inikeza izinzuzo zokulawula futhi ayilimazi i-substrate, okwenza ifaneleke kakhulu ekugcinweni kwama-bearings anembe kakhulu noma izingxenye ezincane.

 

 

2. Ukuncibilika Kwamakhemikhali: Ukususwa Okunamandla Kokugqwala Kokugqwala Okujulile

 

Uma ungqimba lokugqwala lujiyile noma lunezimbobo, ukupholisha ngokomzimba akuphumelelanga futhi kunzima ukukususa ngokuphelele. Ukususwa kokugqwala ngamakhemikhali kufanele kusetshenziswe ukususa ngokushesha i-oxide ngokusebenzisa impendulo yesisombululo.

 

Inqubo Ejwayelekile Yokusebenza:

 

Ukuhlanza kwangaphambili: Kususa uwoyela nokungcola ukuqinisekisa ukuthintana okuphumelelayo phakathi kwesisombululo samakhemikhali esilandelayo kanye nobuso bensimbi;

 

Ukuhlanza Amanzi Ashisayo: Kuphakamisa izinga lokushisa lomsebenzi ukuze kube lula ukusebenza okulinganayo kwe-asidi;

 

I-Pickling Soak: Isebenzisa isisombululo sokususa ukugqwala okuhlanganisiwe esiqukethe i-chromic anhydride, i-phosphoric acid, noma i-sulfuric acid, kanye nezithibi zokugqwala ezingeziwe ukuvikela insimbi eyisisekelo;

 

Ukulawula Izinga Lokushisa: Kushisa isisombululo se-pickling ku-60–95°C (kuye ngokuthi sinjani) ukuze kwandiswe kakhulu izinga lokusabela;

 

Ngemva kokwelashwa: Ngemva kokucwiliswa, ukuhlanza ngamanzi abandayo, ukungathathi hlangothi kwe-alkaline, ukuvimbela ukugqwala, kanye nokuvala uwoyela kokugcina kwenziwa ukuze kuvinjelwe ukungcoliswa kwesibili.

 

Amathiphu Okuphepha: Uketshezi olune-asidi luyagqwala kakhulu. Gqoka njalo imishini yokuzivikela lapho uphatha futhi usebenza endaweni enomoya omuhle. Amanzi angcolile kumele ancishiswe ngokwemithetho futhi akufanele alahlwe ngokunganaki.

 

Kungakhathaliseki ukuthi ufuna ukupholisha izandla ngendlela ethambile noma ukuhlanza ngamakhemikhali ngendlela ephumelelayo, isihluthulelo sisekusebenziseni ikhambi elifanele lesimo esifanele. Ukwazi ukukhetha amathuluzi ngendlela efanele, ukulandelana kwenqubo, kanye nezinqubo zokuphepha ngeke nje kwandise impilo yokuthwala kodwa futhi kuzoqinisekisa ukusebenza kwemishini okubushelelezi nokuthembekile. Ekunakekelweni kwansuku zonke, kunconywa ukuthi kunikezwe kuqala izindlela ezingangenisi kakhulu futhi kusetshenziswe kuphela izindlela zamakhemikhali uma kudingeka ukuze kufezwe imigomo emibili yokubuyisa ukusebenza kanye nokuvikelwa kwezinto.
