Amaqiniso athakazelisayo - Surfaces
I-galvanizing (izigxivizo / izibophelelo)
Lapho i-galvanizing, insimbi yezimpawu noma ukuvala imbozwe ngendwangu encane ye-zinc isebenzisa inqubo ye-galvanic. Lokhu kusebenza njengesivikelo ekugqwaleni. Imikhiqizo eyenziwe ngamagalani ayifanele ukudla.
Ama-galvanized seal: I-Bednorz seal
I-Chromating, engenambala / eluhlaza okwesibhakabhaka (amakepisi)
I-Chromating iyinqubo yobuchwepheshe obungaphezulu. Isetshenziselwa ukunikeza izindawo zensimbi ngezendlalelo ze-chromate ngokusebenzisa isenzo se-chromic acid. Lesi sendlalelo se-chromate sisebenza ngokuyinhloko ukuvikela ekugqwaleni. Ingase futhi isebenze njengesisekelo samajazi alandelayo noma njengesivikelo se-tarnish.

Okungenambala / Okuluhlaza okwesibhakabhaka izindawo ezine-chromatic azinayo i-chromium (VI) -ayikho futhi ngenxa yalokho I-RoHS iyahambisana. I-workpiece ithola umbala oluhlaza okwesibhakabhaka-osiliva kancane, kuyilapho uhlamvu lwensimbi olungaphezulu lugcinwa ngokuphelele. Ukuvikela ukugqwala ngale nqubo kuphansi ngokuqhathaniswa kunemikhiqizo ephuzi yekhromated equkethe i-chromium (VI).
I-Chromating, ephuzi (amakepisi)
I-Chromating iyinqubo yobuchwepheshe bendawo. Isetshenziselwa ukunikeza izindawo zensimbi ngezendlalelo ze-chromate ngokusebenzisa isenzo se-chromic acid. Lesi sendlalelo se-chromate sisebenza ngokuyinhloko ukuvikela ekugqwaleni. Ingase futhi isebenze njengesisekelo samajazi alandelayo noma njengesivikelo se-tarnish.

Izindawo eziphuzi eziqukethe futhi aziqukethe i-chromium (VI). RoHS kuyavumelana. Ukuvikela ukugqwala ngale nqubo kuphakeme ngokuqhathaniswa kunokwemikhiqizo engenayo i-chromium (VI) eluhlaza okwesibhakabhaka.
I-nickel plating (izigqoko)
Indlela evamile yokuhlinzeka ngensimbi ngokuvikela ukugqwala i-nickel plating. Kuye ngokungezwa kwezithasiselo, ingaphezulu lingahluka (i-matt, i-semi-gloss, icwebezelayo, emnyama).

...vala
Ukwandisa ukuvikelwa kokugqwala, i-nickel ngokuvamile ayisetshenziswa njenge-coating eyodwa, kodwa njengengxenye yesistimu ye-multi-layer, isibonelo ngokuhlanganiswa nethusi noma i-chromium.
I-Powder coating (ukuvalwa)
I-Powder coating uhlobo lokuqedwa kwendawo yensimbi esetshenziswa kakhulu namuhla. Ngesikhathi se-powder coating, ucezu lokusebenza lumbozwe ngopende lwempushana usebenzisa izinqubo ze-electrostatic.

Ngokuphambene nopende omanzi, upende oyimpushana awuncibiliki futhi awukhiphi futhi ngenxa yalokho awuhambisani nemvelo uma kuqhathaniswa. Ingasetshenziswa ezingqimbeni eziwugqinsi futhi inokuguquguquka okukhulu kwendawo. Ngakho-ke ukugcoba kwempushana kuqinisekisa ukuvikeleka okuhle kakhulu kokugqwala nokumelana okuphezulu nokucindezeleka komshini kanye nesimo sezulu ne-asidi.
I-V2A insimbi engagqwali (izinsimbi)
I-V2A insimbi engagqwali evame ukusetshenziswa. Alizwani namanzi kuphela, umhwamuko wamanzi noma umswakama, kodwa futhi nama-asidi aphilayo nama-inorganic abuthaka kanye namazinga okushisa aphezulu kakhulu naphansi kakhulu. Inokupholiseka okuhle kakhulu futhi nokuhleleka okuhle ikakhulukazi ngokudweba okujulile, ukugoqa, ukwakheka kwamaroll, njll.

Insimbi ye-V2A isetshenziswa, phakathi kwezinye izinto, ezimbonini zokudla, ezemithi nezimonyo, ekwakhiweni kwemishini yamakhemikhali, ekwakhiweni kwezimoto, ekwenzeni izinsimbi zokuhlinza nasezikhungweni zenhlanzeko.
Tinning (seals)
I-Tinning ihlanganisa ukufaka ungqimba oluncane lukathayela ensimbi usebenzisa inqubo ye-galvanic. Ukuvikela ekugqwaleni akusebenzi kahle kulokhu kwelashwa okungaphezulu njengokufakwa uthayela, kodwa ama-seal anendawo ehlanganiswe ngothayela aphephile ekudleni.

Ama-tinned seals: Tyden Seal
I-Anodizing (ama-wire seals)
Inqubo ye-anodizing (futhi I-anodising ebizwa) indlela yobuchwepheshe obungaphezulu esetshenziselwa ukwakha ungqimba oluvikelayo ku-aluminium. Insimbi engaphezulu kwayo iguqulwa ibe yi-oxide noma i-hydroxide kusetshenziswa inqubo ye-electrochemical.

...vala
I-anodising yakha ama-micrometer ambalwa azacile kodwa aqine kakhulu avikelayo amelana nesimo sezulu nokugqwala. Izingxenye ze-aluminium anodized nazo zingaba nombala. Ngale njongo, izingulube zombala zishumekwe kungqimba lwe-anodized.
