Ekukhiqizweni kwezimboni. Ama-Casters, njengengxenye ebalulekile yobuchwepheshe bayo bokwelapha ubuso kubalulekile ukuthuthukisa ubuhle, ukuqina kanye nokumelana nokugqwala komkhiqizo. Ukuhlanza ubuso njengokwelashwa okuvamile kobuso. Kusetshenziswa kabanzi ekwelapheni ubuso kwama-alloys e-caster. Lesi sihloko sizochaza izindlela eziningana ezivamile zokuhlanza ubuso, okuhlanganisa i-cyanide galvanizing, i-zincate galvanizing, i-chloride galvanizing, kanye ne-sulfate galvanizing. Kwenzelwe ukunikeza abafundi ireferensi yobuchwepheshe ephelele.
1, i-Cyanide galvanization
I-Cyanide galvanizing, ngenxa yamandla ayo aphezulu okuhlakazeka kanye nekhwalithi enhle yokubopha. Ngesinye isikhathi yayinesikhundla esibalulekile embonini yokubopha ngogesi. Kodwa-ke. Ngenxa yemvelo enobuthi obukhulu be-cyanide ngokwayo kanye nosongo olungase lube khona emvelweni. Ukusetshenziswa kwayo kunqunyelwe kakhulu. Noma kunjalo, ukuthuthukiswa kwezinqubo zokubopha ngogesi ezine-cyanide ephansi (i-microcyanide). Okwenza kube nokwenzeka ukuqinisekisa ikhwalithi yomkhiqizo ngenkathi kunciphisa izingozi zemvelo. Ngaphansi kwenqubo yokubopha ngogesi ene-cyanide, ikhwalithi yomkhiqizo ihle kakhulu ngemva kokubopha ingxenye yehadiwe ye-caster. Ikakhulukazi ngemva kokuba ukubopha ngombala sekuphelile, imibala ihlala ikhanya isikhathi eside.
2, imigomo nemigomo ehlobene ne-zincate galvanized caster welding
Inqubo ye-zincate galvanizing iyindlela engcono kakhulu kune-cyanide galvanizing. Njengamanje, zihlukaniswe kakhulu ochungechungeni lwe-"DPE" lwe-Wuhan Institute of Materials Protection kanye nochungechunge lwe-"DE" lwe-Guangdian Institute. Zombili zi-zincate galvaning ezinezithasiselo ze-alkaline. Zinezici zesakhiwo se-columnar lattice se-plating, ukumelana okuhle kokugqwala, futhi zifanelekela i-color galvanizing. Ukwakheka kwayo okuvamile kufaka phakathi i-NaOH, i-ZnO, kanye nezinye izithako ezithile. Isibonelo, inhlanganisela ye-"DPE-II" kanye ne-ethanolamine. Le nqubo idinga ukulawulwa okuqinile kokwakheka kwesisombululo se-plating kanye nezimo zenqubo, njenge-pH, izinga lokushisa, kanye nobuningi bamanje, ukuqinisekisa ikhwalithi ye-plating. Ngemuva kokuthi umkhiqizo uphume ethangini, kufanele udlule ochungechungeni lwezinyathelo zangemva kokucubungula, njengokugeza, ukupholisha, ukudlulisa umoya kanye nokomisa ukuze uthole imiphumela emihle.
3, i-chloride galvanization
Inqubo yokugaya i-chloride isetshenziswa kabanzi embonini yokugaya ihadiwe ye-caster. Iphesenti lingaphezu kuka-40%. Ukubonakala kwenqubo okungabonakali (okuluhlaza okwesibhakabhaka noma okumhlophe kwesiliva) kufana nokwe-chrome plating. Futhi izindleko ziphansi kakhulu. Izindlela ezijwayelekile zokugaya i-chloride zifaka i-KCl, i-ZnCl_2, i-H_3BO_3 (i-buffer), kanye nezibani ezithile. Le nqubo ifaneleka kakhulu ekukhanyeni okumhlophe (okuluhlaza okwesibhakabhaka, okumhlophe kwesiliva). Phakathi kwazo, ukubomvu kwesiliva ngenxa yombala wayo ozinzile. Ngokuvamile kukhethwa njengokukhetha kokuqala. Kodwa-ke, kubalulekile ukuqaphela ukuthi ukumbozwa kwe-Chloride galvaning, lapho kuvezwa emoyeni isikhathi eside, yi-membrane ethambekele ekushintsheni kombala. Kuthinta ukubukeka kanye nokumelana nokugqwala komkhiqizo. Ngakho-ke. Emsebenzini, kuyadingeka ukuthatha izinyathelo ezifanele ukuvimbela ukubola kombala.
4, i-sulfate galvanization
Inqubo ye-sulfate galvanizing, enezindleko zayo eziphansi kanye nokufaneleka kwayo kokugoba okuqhubekayo (isb., ucingo, umcu, njll.). Indawo embonini ye-electroplating. Izinhlobo ezijwayelekile zale nqubo zifaka i-ZnSO_4, i-H_3BO_3, kanye nezibani ezithile. Inani le-pH lokugoba kwe-sulfate ngokuvamile lilawulwa phakathi kuka-4.5 no-5.5. Ngokulungisa ukwakheka kwesisombululo sokugoba kanye nezimo zenqubo, ukugoba kwe-A okunokumelana okuhle nokugqwala nokukhanya kungatholakala. Kodwa-ke. Uma kuqhathaniswa nezinye izinqubo zokugoba, ukugoba kwe-Sulfate kungaba ngaphansi kancane ngokwe-gloss kanye nokufana kokugoba.
amazwi okuphetha
Ngamafuphi. Ama-casters ahlanganiswa ngezindlela ezahlukahlukene. Indlela ngayinye inezinzuzo zayo ezihlukile kanye nobubanzi bokusetshenziswa. Empeleni. Kufanele isekelwe endaweni ethile yokusetshenziswa kanye nezidingo zokusebenza kwe-caster. Khetha inqubo efanele yokufaka i-galvanizing. Okwamanje. Ngemithethonqubo yezemvelo eqinile kanye nentuthuko kwezobuchwepheshe bokufaka i-plating, inqubo yokufaka i-galvaning enobungani nemvelo, esebenza kahle futhi engabizi kakhulu izoba yindlela yokuthuthukiswa kwesikhathi esizayo.
