Okugeza kukagesi ngezandla zakhe. I liner kanye Ukushisa okugeza kukagesi

emagama latayelekile "zegolide", "isiliva-kuhlinzwa", "i-chrome" noma "nickel" isivele siqine isichazamazwi yomuntu yesimanje, futhi beqonda kubo cishe ngokuzenzakalelayo. Akekho ngisho ecabanga ukuthi wonke la mazwi ukufihla ubuchwepheshe kuzovumela umuntu ukufinyelela ezingeni impucuko yesimanje - Electroplating.

Electroplating - yini le nqubo?

Inqubo electrochemical lapho i kagesi kuyinto sebethule izinsimbi ku- surface akhethiwe, ngokuthi Electroplating. inqubo enjalo singasebenza iyiphi into, ngisho non-izinsimbi. Lokhu kwakuwumnikelo ka-juqu for ukusetshenziswa kabanzi Plating kulezo zimboni. Nayo ukwazi ukudambisa, isilivere-chrome kuhlinzwa noma yiziphi izinto ennobling ukubukeka kwabo zokuhlobisa noma ekushintsheni izakhiwo ngokomzimba futhi amakhemikhali ebusweni ngendlela luyingxenye esisebenzayo (ukwandisa bafake ukumelana, ukuthuthukisa ukumelana abezindaba nolaka futhi t. D.). Isisetshenziswa nansi okugeza kukagesi.

izinhlobo Plating

Kunezinhlobo ezimbili zama-lobu buchwepheshe ziye kabanzi hhayi kuphela amagatsha amaningi umkhakha yesimanje, kodwa futhi ekhaya. Umsuka - electroforming - ihlose ukwakha amakhophi ngqo into imali Laphezu yalezi metal. Okwesibili, ezivamile futhi ekhaya emsebenzini, ukuhlinzeka mncane - akukho mkhulu kunokhalo unwele lomuntu - lokunameka bonke ubuso into bese ubizwa Electroplating.

Uyini okugeza Plating?

Njengoba izinqubo kukagesi kwenzeka ngenxa electrolysis Yiqiniso, ukuthi wasebenzisa izixazululo electrolytic kanye nemishini ekhethekile mechanical kagesi kanye. okugeza kukagesi - inhlanganisela yazo zonke lezi zitho inqubo, kodwa izingxenye eziyinhloko, okuyinto sokukhula, kukhona isixazululo (electrolyte) , futhi umthamo ngoba. Lokhu kubalulekile ikakhulukazi uma kukhona inkulumo mayelana nokusetshenziswa Electroplating noma electroforming ekhaya.

Ukuze iziqukathi electroforming bayanda izidingo jikelele okuyinto, naphezu kweqiniso lokuthi lezi izinhlobo zezitsha zokuphatha kugcwele yonke banayo ngokuqinile ukuhambisana. Bafanele Friend futhi engenawo amakhemikhali ukuze ikhambi esetshenziswa, wakwazi ukugcina izimo edingekayo ezishisayo (Ukushisa Electroplating zokugeza kanye nokupholisa Kumele alawulwe), kanye ukhululekile futhi ephephile ukusebenza. Nakubhavu zenziwa ngezinto ezahlukene.

Izindlela ukuhlaziya Plating zokugeza

Ngenxa yokusebenza isikhathi yesimanje kukhona amathuba amasha ukuhlaziya electrolyte esetshenziswayo Electroplating. Kubalulekile yalokho ezinhle inqubo, iyunifomu ngaphezulu bese enamathela okuhlala. Ukuhlaziya Electroplating zokugeza e ngezimo esiphila kuzo kungase kwenziwe usebenzisa zamakhemikhali physico-chemical izindlela. Esimeni sesibili, izifundo photometric, polarographic, amperometric nezindlela potentiometric ezinikeza imiphumela engcono uma izama yokwakheka electrolyte.

Ukuvikelwa amathangi kukagesi

Enye yezinkinga izinqubo electrochemical - kuyisivikelo amathangi emiphumeleni elimazayo yesixazululo electrolyte (acid noma alikhali) lapho electrolysis kwenzeka. Uma okugeza wenziwe impahla kokungathathi hlangothi ezifana plastic, akunankinga. Kodwa lokhu kungenzeka kuphela uma amavolumu encane. Uma sithatha ukufakwa ezimbonini ke Electroplating izimboni isixazululo isitsha esenziwe metal. Kulokhu, kunesidingo ukuze bazivikele:

- contact necebo ukuthi ihlinzeka ukuphila isikhathi eside;

- ukugqwala metal, kudala ukungcola ngokungadingekile isixazululo;

- ukuhlanekezela nokuguqulwa emkhakheni kagesi.

Ukuvikelwa enjalo ingase ikuhlinzeke ngamanye Electroplating zokugeza abami olwenziwa polymeric ishidi izinto esebenzisa hot air Welding.

Ukwenza ikhaya-Plating zokugeza

Abafisa ukuba evele lashukumisa ekhaya lakho noma igalaji impela eningi. Kodwa-ke kufanele kuqashelwe ukuthi le nqubo akuphephile. evala Iyingozi futhi kuqhume, izixazululo ezonakalisayo ngisho anobuthi, ukusetshenziswa kukagesi kwenza kube nzima ngokombono ukuphepha. Kodwa imisebenzi elula njengokwenza Plating ithusi, i-chrome Plating, nickel Plating okugeza izinto ezincane ingalandwa ngokurhaba. Futhi ngisho esimweni esinjalo, izidingo ezibalulekile eziningana kumele kwenziwe:

- I-esitsheni isixazululo kumele ukuqina, engenawo amakhemikhali kanye Kwe-dielectric Heating;

- edingekayo ukupholisa;

- khona imali eyanele ngamanzi acwebileyo - inqubo elula kudinga ukusetshenziswa mayelana ezinhlanu izona;

- khona isitsha futhi indlela zokuyithena imfucuza Liquors futhi effluents.

Samuntu elula okugeza Plating tingentiwa amathini plastic, wayinquma cap kusuka entanyeni kanye nokuqinisa indlela enhle ezinhlangothini impahla abalwazi kahle ulimi. Ngokulandelayo, udonga amandla asikiwe, ukuguga noma yezimoto iwindi lwezimpawu. Isinyathelo esilandelayo ukukhweza ikhava ngosizo upiyano buxhomeke komunye uhlangothi ibhokisana lokugcina itiye noma ikhofi kanye Ukugunda ukugibela ikhava odongeni ngakolunye uhlangothi lomkhumbi. Umlomo esivalweni exhunywe kwi-hose zokususa umusi out - qeda elula.

Manje okusadingeka kwenziwe engxenyeni engenhla bomkhumbi line cutoff for ezintathu-imbobo contact izinduku. Ngenduku desirably eyenziwe ipayipi ngethusi 10-20 mm ububanzi, obukhulu ngabafaka kangcono. plyuschatsya uphela kuzo ngemibhobho futhi babhola izimbobo ukuxhuma izigxobo kusukela kwamandla. On induku, ibekwe eduze emaphethelweni hang anode amapuleti futhi axhunyiwe emthonjeni omuhle. Induku emaphakathi okwesikhashana okuyingxenye, kuyinto cathode exhunywe kwi-lead ezimbi. zamanje futhi voltage akhethiwe kuncike umthamo okugeza.

AmaSu okuzenzela Electroplating zokugeza

Indlela elula isikimu Plating okugeza kuhlanganisa ingqikithi imisebenzi emithathu: wokulungiselela inqubo empeleni galvanizing futhi aliqede. Eyokuqala liqukethe yokuhlanza, degreasing, etching abese ezipholisha bento noma ingxenye - ukuqeqeshwa. Isinyathelo sesithathu ivumela ukuletha kakade camera nge ungqimba metal entweni "lezimpahla" hlobo, by passivation, futhi buffing t. D. operation ngamunye kufanele kuqedwe ngokuhlanza impahla ngamanzi abandayo futhi ihlanzekile. Futhi uma izinto okucutshungulwe izixazululo ane-alikhali, qiniseka ukwenza izingubo, ashisayo, amanzi kuqala bese abandayo.

Into, edingekayo ukuze elingenamikhono, ixhunywe umqhubi amadivayisi ezimbi (cathode) bese ngihlaliswa le electrolyte. Phambili omuhle ixhumeke electrode ka enamathela metal (anode), nakho lokhu iwela isixazululo. Electrolysis ukwenza anode encibilikayo (+) kanye metal imali kwi workpiece, le cathode (-).

Inani Electroplating ekukhiqizeni yesimanje

okugeza kukagesi, lapho electroforming noma Electroplating inqubo, yezomnotho kokubili ingane kwenqubekela phambili, kanye nokushayela yayo amandla. Ngenxa sibonga electroplated ezinengilazi ngcono izici futhi indlela izingxenye, kunciphisa izindleko zokukhiqiza yabo abayifunayo ukunemba eliphakeme conjugation inyuka ukugqoka ukumelana naso futhi kwenze ukugqwala ukumelana bayanda.
