Koqweqwe lwawo

Enamel,njengomhlobiso wesikhathi eside okhona kanye nezinto ezivikelayo, isetshenziswa kabanzi ekukhiqizeni izimboni kanye nempilo yansuku zonke.Akuyona nje inhle futhi ihlala isikhathi eside, kodwa futhi inokuqina okuhle kwamakhemikhali nokumelana nokugqwala.Ngokombono wokukhiqizwa kwezimboni, inqubo yokukhiqiza koqweqwe lwawo kuyinqubo eyinkimbinkimbi ehlanganisa isayensi yezinto zokwakha, ubunjiniyela bamakhemikhali, nobuchwepheshe bokucubungula okuhle, okubandakanya ukukhethwa kwezinto ezingavuthiwe, ukulungiswa, ukumbozwa, nokudubula.

1. Incazelo kanye nokwakheka koqweqwe lwawo

Uqweqwe lwawo luyinhlanganisela eyenziwe ngokuncibilikisa izinto eziyingilazi ezingaphili ku-matrix yensimbi nokuyicwilisa emazingeni okushisa aphezulu.Izingxenye eziyinhloko zifaka i-glaze (i-silicate, i-borate, njll.), ama-colorants, ama-fluxes, nama-ejenti aqinisayo.Phakathi kwazo, i-glaze iyisisekelo sokwenza ungqimba lwe-koqweqwe lwawo, olunquma izakhiwo ezingokwenyama namakhemikhali zoqweqwe lwawo;Ama-colorants asetshenziselwa ukuxuba imibala;I-Flux isiza ukugeleza kwe-glaze ngesikhathi senqubo yokudubula, iqinisekisa ubuso obushelelezi be-glaze;Izithuthukisi zithuthukisa amandla emishini kanye nokunamathela kwe-coating.

2. Ukulungiswa kwezinto zokusetshenziswa

Isinyathelo sokuqala ekukhiqizeni koqweqwe lwawo ukukhethwa kanye nokuphathwa kusengaphambili kwezinto zokusetshenziswa.I-substrate yensimbi ngokuvamile yenziwe ngensimbi, insimbi, i-aluminium, njll., futhi impahla efanele nokuqina kufanele kukhethwe ngokuvumelana nezidingo zohlelo lokusebenza.Ukulungiswa kwe-glaze kuhilela ukuxuba izinto ezihlukahlukene zokusetshenziswa ngokulingana, ukuzigaya ngezinga elithile lokuqina, ukuqinisekisa ukufana kanye nekhwalithi yokugqoka kokugcina.Kulesi sigaba, ukuhlolwa okuqinile kwempahla eluhlaza kuyadingeka ukuze kuqinisekiswe ukuthi akukho ukungcola, ukuze kungathinti ikhwalithi nokusebenza koqweqwe lwawo koqweqwe lwawo.

3. Ukwelashwa kwendawo

Ngaphambi kokumbozwa, i-substrate yensimbi idinga ukuhlanzwa futhi iphathwe ukuze kukhishwe amafutha, isikhumba se-oxide, nokunye ukungcola.Izindlela ezivamile zihlanganisa ukususa amafutha, ukugeza i-asidi, i-phosphating, njll. Lesi sinyathelo sibalulekile ekuthuthukiseni amandla okubopha phakathi koqweqwe loqweqwe lwawo kanye ne-substrate yensimbi.

4. inqubo Enamelling

Inqubo yokumboza ingahlukaniswa ngezigaba ezimbili: indlela eyomile kanye nendlela emanzi.Izindlela ezomile ngokuyinhloko zihlanganisa ukufafaza kwempushana ye-electrostatic kanye nokucwiliswa kombhede wokucwiliswa kombhede, ezifanele ukukhiqizwa okuzenzakalelayo okukhulu, okungalawula ngempumelelo ukujiya kokunamathela, futhi kuvumelana nemvelo.Indlela emanzi ihlanganisa ukumbozwa kwama-roll, i-dip coating, kanye ne-spray coating, ezifaneleka kakhulu izimo eziyinkimbinkimbi kanye nokukhiqizwa kwenqwaba encane, kodwa ijwayele ukungcoliswa kwemvelo kanye nezinkinga zokumboza ezingalingani.

5. Ukushiswa

Umkhiqizo oboshwe udinga ukushiswa ekushiseni okuphezulu, okuyisinyathelo esibalulekile sokwenza ungqimba lwekhwalithi ephezulu ye-koqweqwe lwawo.Izinga lokushisa lokudubula ngokuvamile liphakathi kuka-800 ° C no-900 ° C, kuya ngefomula ye-glaze kanye nohlobo lwe-substrate.Phakathi nenqubo yokudubula, i-glaze iyancibilika futhi imboze ngokulinganayo indawo yensimbi.Ngemva kokupholisa, yakha ungqimba oluqinile nolubushelelezi koqweqwe lwawo.Le nqubo futhi idinga ukulawulwa okuqinile kwezinga lokushisa, isikhathi sokuvala, nezinga lokupholisa ukuze kuvinjelwe ukwenzeka kweziphambeko njengokuqhekeka namabhamuza.

6. Ukuhlolwa kwekhwalithi kanye nokucubungula ngemva kokucubungula

Ngemuva kokudubula, imikhiqizo yoqweqwe lwawo kumele ihlolwe ikhwalithi eqinile, okuhlanganisa nokuhlolwa kokubukeka, ukuhlolwa kokubola, ukuhlolwa kwamandla emishini, njll. Imikhiqizo engafanelekile idinga ukulungiswa noma ukuchithwa.Ukwengeza, kuye ngokusetshenziswa okuhlosiwe komkhiqizo, ezinye izinyathelo ezifana nokuhlanganisa nokupakishwa zingadingeka.

7. Inkambu yohlelo lokusebenza

I-enamel isetshenziswe kabanzi emikhakheni eminingi ngenxa yokusebenza kwayo okuhle kakhulu.Embonini yemishini yasendlini, njengamahhavini, imishini yokuwasha, izifudumezi zamanzi, njll., i-koqweqwe lwawo alugcini nje ngokujabulisa futhi kulula ukuyihlanza, kodwa futhi imelana nokushisa okuphezulu nokugqwala.Emhlobiso wezakhiwo, amapuleti ensimbi ye-enamel avame ukusetshenziselwa izindonga zangaphandle, imigudu, iziteshi zesitimela, njll ngenxa yemibala yazo ecebile kanye nokumelana nesimo sezulu esiqinile.Ngaphezu kwalokho, imishini yezokwelapha, okokusebenza kwamakhemikhali kanye neminye imikhakha nayo isebenzisa kakhulu imikhiqizo yoqweqwe lwawo, isebenzisa ngokunenzuzo ukuzinza kwayo okuhle kwamakhemikhali kanye nezici ezilula zokubulala amagciwane.

Isiphetho

Sekukonke, ukukhiqizwa kwemboni yoqweqwe lwawo kuyinqubo eyinkimbinkimbi ehlanganisa amasu endabuko nobuchwepheshe besimanje.Imikhiqizo yayo eqediwe ayibonisi nje kuphela inhlanganisela ephelele ye-aesthetics nokusebenza, kodwa futhi ibonisa inqubekelaphambili yesayensi yezinto ezibonakalayo kanye nobuchwepheshe bokukhiqiza.Ngokuthuthuka okuqhubekayo kobuchwepheshe, imikhiqizo yoqweqwe lwawo ibheke endaweni evumelana nemvelo, ephumelelayo, futhi enemisebenzi eminingi, ihlangabezana ngokuqhubekayo nezidingo zemikhakha ehlukene.

Noma yimuphi umbuzo mayelana nezingxenye ze-Casting, Forging noma Machining, sicela ukhululeke ukuxhumana nathi nganoma yisiphi isikhathi.
