Imikhiqizo ye-aluminium die casting surface treatment

Imikhiqizo ye-aluminium die castukwelashwa kwendawo

Imikhiqizo ye-aluminium alloy die casting, ukwelashwa okungaphezulu ngokujwayelekile: ukufafaza okuyimpushana (ukufafaza ngempushana), upende, ukufutha uwoyela, i-oxidation, i-sandblasting, i-electroplating nokunye. Ngokusho ukushuba kanye isiphetho ukwelashwa surfacei-aluminium die castingimikhiqizo.

1, ukufutha ngempushana kuwukufafaza i-powder coating ebusweni bomsebenzi wokusebenza nge-powder spraying equipment. Ngaphansi kwesenzo se-electrostatic, impushana izokhangiswa ngokulinganayo phezu kwendawo yokusebenza ukuze yakhe ukunamathela okuyimpuphu. Ukufakwa kwe-powder ngemva kokubhaka okuphezulu kokushisa, ukulinganisa nokuphulukisa, kube yimiphumela ehlukene (izinhlobo ezahlukene zemiphumela yokugcoba impushana) ye-coating yokugcina; Ukufafaza kwe-powder kuphakeme kunokudweba umdwebo emandleni emishini, ukunamathela, ukumelana nokugqwala, ukumelana nokuguga nezinye izici, futhi izindleko zakhona nazo ziphansi kunezo zokudweba kwesifutho ngomphumela ofanayo.

Ukufuthwa kwempushana, ngokuvamile kuhlukaniswa kube yimpushana yangaphandle nempushana yasendlini. Amaphethini angalungiswa emiphumeleni ehlukahlukene, njengokubushelelezi, isihlabathi, igwebu, njll.

2, inqubo yokubhaka upende wangempela ukusebenzisa i-aluminium alloy phosphating ngemuva kokufafaza, ukufafaza ngemuva kokubhaka, ukunamathela okunjalo akuyona nje i-anticorrosive futhi ekhanyayo ukumelana nokugqoka, akulula ukuwa.

Imikhiqizo ye-Aluminium die Casting Pretreatment ebusweni

(1) 1 ukususwa kwamafutha; 2 amanzi; 3 ukuphefumula; 4 wageza; 5 iwashi; 6 wageza; 7 phosphating; 8 wageza; 9 wageza; 10 ukomisa;

Okwesithathu, ukufuthwa kwamafutha yigama lokucutshungulwa kwe-surface enamathela yemikhiqizo yezimboni, ukucutshungulwa kokufafaza uwoyela ngokuvamile okukhethekile ngokufafaza uwoyela wepulasitiki, ukuphrinta kwesikrini, ukuphrinta kwephedi; I-EVA, irabha nomunye umbala wezinto zezicathulo, ukuphrinta kwesikrini. Ngomugqa wokufafaza, umugqa wokuphrinta kwesikrini, umshini wokuphrinta wephedi nezinye izinto zokusebenza, futhi ngokuya ngezidingo zamakhasimende, ukukhiqizwa kokumelana nokushisa okuphezulu, ukumelana nokungqubuzana, ukumelana ne-Uv, ukumelana notshwala, ukumelana nophethiloli neminye imikhiqizo. Ukucutshungulwa kobubanzi: imikhiqizo ye-elekthronikhi: upende ojwayelekile wesifutho, upende we-PU, upende werabha (upende wokuzwa), (ofana ne-U disk, MP3, ikhamera, imikhiqizo yenethiwekhi ye-peripheral neminye imikhiqizo ye-elekthronikhi. Ingafafaza izinkinga ezinzima ezihlangabezane nazo ekubunjweni komjovo, njengemigqa yegesi, amalunga okuhlanganisa, njll., abe nolwazi lokufafaza upende wenjoloba (upende wesandla), ube nobuchwepheshe bokuphinda upende ngesandla.

4, i-oxidationI-aluminium alloy surface oxidation, ilungele i-oxidation conductive, i-aluminium noma iphrofayili ye-aluminium, ifanele i-anodic oxidation.

Umbala we-aluminium oxidation we-aluminium ngokuvamile ungokwemvelo, uluhlaza okwesibhakabhaka

1. I-anodic oxidation yenziwa ngaphansi kwesimo se-voltage ephezulu, okuyinqubo yokusabela kwe-electrochemical; I-conductive oxidation ukusabela kwamakhemikhali okumsulwa okungadingi ugesi kodwa ukucwiliswa esixazululweni esiwuketshezi. 2. I-anodic oxidation ithatha isikhathi eside, ngokuvamile amashumi emizuzu, kuyilapho i-conductive oxidation ithatha imizuzwana embalwa. 3. Ifilimu ye-anodic oxidation inama-microns ambalwa kuya kumashumi ama-microns, kanye nefilimu eqinile futhi engagugi, kanye ne-conductive oxidation ekhiqizwa cishe ama-microns angu-0.01-0.15. Ayigqoki kahle kakhulu, kodwa iqhuba ugesi futhi imelana nokugqwala kwe-atmospheric, okuyinzuzo yayo.

5, ukuqhunyiswa kwesihlabathi

Ukufafaza ungqimba lwesihlabathi ebusweni beingxubevange ye-aluminium pubuciko bungathuthukisa i-coefficient yokungqubuzana kwendawo yokuxhumana futhi kuthuthukise ukwethembeka koxhumano. Ukujiya kwesihlabathi, okusanhlamvu nakho kuhluke kakhulu.

6, i-electroplating

I-Electroplating iyinqubo lapho insimbi noma i-alloy ifakwa phezu kwendawo yokusebenza nge-electrolysis ukuze kwakheke ungqimba lwensimbi olufana, oluminyene noluhlangene, olubizwa nge-electroplating. Ngokuqondakala kalula, kuwushintsho olungokomzimba namakhemikhali noma inhlanganisela. Ukusetshenziswa kwenqubo ye-electroplating ngokuvamile siyisebenzisela lezi zinhloso ezilandelayo: A. Anti-corrosion B. Umhlobiso ovikelayo C. Ukuvimbela ukuguga!
