Ndezvipi zvakajairika screw pamusoro pekurapa maitiro?

Maitiro ekugadzira nzvimbo yemusoro pamusoro pechinhu chinotsauka chinosiyana neye substrate maererano neyechinyowani, mumuviri, uye makemikari anozivikanwa sekurapwa kwemusoro. Kurapa kwepasi kunoshandiswa kugutsa zvirevo zvezvinhu zvakaita sechigadzirwa corrosion kuramba, pfeka kurwisa, uye aesthetics.

Kuwedzera kune iyo yekutanga maitiro, kupokana uye kutarisa kwemavara kunofanirwa kuitirwa kana uchisarudza screws. Forscrews.

Zvinoenderana nerudzi rwemukati rwechikara, inogona kukamurwa mumapoka anotevera:

Nhema dzakasviba

Zvakajairika demascrewsinonyanya kusanganisira black oxidation kurapwa, electroplating, uye electrophoresis.

Dema oxidation kurapwa

Black Oxidation kurapwa inzira yakajairika yemakemikari kurapwa, chinangwa ndechekubereka iyo yefirimu yehusiku pane iyo simbi pamusoro yekuparadzanisa mweya uye kudzivirira ngura.

Maitiro acho ndewekushandisa oxidant kune oxidize pamusoro peiyo simbi mune dense uye yakatsiga ferroferrric oxide. Iyi yakatetepa lerroferrric oxide inogona kuchengetedza zvinobudirira mukati mesimbi kubva kune oxidation. Yakakamurwa kuita kupisa kwakadzika uye kupisa kwakanyanya.

Ferroferrer oxide yakaumbwa pakudziya kwakadzika (anenge 350 ° C) yakasviba dema, inozivikanwa seyekuputika. Ferroferrer oxide yakaumbwa ne oxidation pakudziya kwakanyanya (anenge 550 ° C) iSky bhuruu, inozivikanwawo sekurapwa kwacho. Kurapa kwebhuruu kunowanzoshandiswa mukugadzira chombo, uye kurapwa kwakasviba kunowanzoshandiswa mukugadzirwa kwemaindasitiri.

Oxidizing iyo simbi yemhepo kune dense, yakatsetseka ferroferrric oxide inoda iyo yakasimba oxidant. Iyo yakasimba oxidant inoumbwa ne sodium hydroxide, Sodium nitrite, uye Trisodium phosphate. Kana zvashanduka

Electroplating

Electroplating ndiyo nzira yekushandisa electrolysis kuti ive jasi remafirimu esimbi kana mafirimu ezvivakwa. Chinangwa ndechekuvandudza kupfeka kupokana, kupokana, uye aesthetics.

Kune marudzi maviri ezvikamu zvitema: dema zinc plating uye dema nickel plating.

Nhema Zinc yakarongedzwascrews

Dema zinc plating rudzi rweanti-oxidation yekugadziriswa yesimbi, iyo yakakodzera zvigadzirwa zveHardware. Zinc inoitwa nemakemikari uye nyore oxidized uye yakasviba mumhepo. Mushure mekunge organizzing, inobatwa ne chromate yekuvhara kirimita yekushandurwa kwemakemikari pane zinc, kuitira kuti simbi inoshanda iri mumamiriro ezvinhu epasi, ayo ari ekurapa kweZinc Layer. Iyo firimu rePassivation inogona kukamurwa kuita chena

Kazhinji, maitiro ekugadzira electroplating dema zinc iri degreasing-kuchenesa-isina simba acid-electro-yekuchenesa-yekuchenesa-yekushambidza-kusimbisa.

Nhema Nickel Yakarongedzwa Screws

Kazhinji, maitiro eElectroplating dema Nickel deskecing - Kuchenesa - Kuchenesa Acid

Iyo dema nickel yekubatanidza inowanikwa kubva kune dema nickel yekugezera ine 40-60% nickel, 20-30% zinc, 10-15% sarufa, uye inenge 10% organic nyaya. Ruvara rwema dema runokonzerwa nekuvapo kweBlack Nickel Sulfide muCoating nekuda kwekudzikisira kweiyo thiocyanate pane cathode kusunungura sulfide ions. Pasi pemhangura yakawedzerwa mukuita, uye basa guru ndere kuita kuti nickel plating zviri nyore mune post maitiro uye kugadzirisa kupokana kwecrew of the screw.

Electrophoresis

Electrophophoresis inoreva nezvechishandiswa mune zvimedu zvakabhadharwa kuenda kuMagetsi zvemagetsi zvemagetsi zviri pasi pechiitiko chemunda yemagetsi.

Yemagetsi dema ndeyekushandisa kwemunda wekunze wemagetsi kuti uite zvimedu zvekuti zvidimbu uye zveshuwa zvakamiswa muElectropharesis Solution Electrophoretic dema inoshandiswa zvakanyanya muindasitiri, kutora iyo dema maitiro semuenzaniso: Degreasing - Kuchenesa - Pelephoretic Paint - Kuoma. Inogona kukamurwa muAnocic Electrophoresis (Resin inova isina kunaka ion mushure meinkazation) uye Cathodic Electrophoresis (Resin inova yakanaka ion mushure meElectrophoresis). Kuenzaniswa neyakaitwa pendi, ine chekuita nekuvaka zvakanyanya, kusvibiswa kushoma uye kukuvadza nharaunda uye kupokana kwaro kune imwe nguva yemunyu kana mari uye kupokana kwekuita kwavo kwakafanana neiyo yerudzi rwechiratidzo.

White yakarongedzwa zviyero

Zviitiko zvevachena zvakaringana zvinonyanya kusanganisira electroplating chena nickel, chena zinc, zvichingodaro.

Electroplating White Zinc

White Zinc yakarongedzwascrews

Maitiro ekugadzira electroplating White Zinc iri degreasing-kuchenesa-isina simba acid activation-Electro-emagetsi-kuchena-kuchenesa-kuchenesa. Musiyano weBlack Zinc ndewekuti hapana pendi-inosimbisa pendi, uye mhinduro yepamberi yakasiyanawo. White Shona

Iyo Corrostion Kudzvinyirira yeZinc White iri nani pane iyo yeWhite INICEL, uye kutaridzika kwayo yakasviba pane iyo ye chena nickel.

Electroplating White Nickel

White Nickel Yakarongedzwa Screws

Maitiro ekugadzira electroplating chena nickel is degreasing - kuchenesa - kushaya simba acid. Maitiro ekugadzira electroplating chena nickel uye electroplating dema nickel zvakafanana, mutsauko wakarara mumamiriro ezve extroplating solution, pasina kuwedzera kweZinc Sulfide.

Mamwe mavara akaiswa mavara

Ruvara rwakatsemurwascrews

Iyo plating yemamwe mavara inonyanya kusanganisira bhuruu zinc, green zinc, ruvara rwezin, uye dcromet.

Iyo Electroplating maitiro ebhuruu zinc uye green zinc yakaenzana neiyo yeiyo chena zinc. Blue Zinc is a Passvated Zinc oxide firimu rine 0.5-0.6 mg / dm2 yetatu tromium. Green Passivation iri nekuda kwekuti iyo sosi yepasirivation ine phosphate ion, uye iyo yakasvibirira girini inoumbwa ne chromate uye phosphate.

Iyo Corrostion Kudzvinyirira yeBlue Zinc iri nani pane iyo yeWhite Zinc, uye iyo Corrostion Kudzvinyirira yeGreen Zinc iri nani pane iyo yebhuruu zinc.

Ruvara Zinc ane hukama hwakanaka hwekugadzirisa. Maitiro ePassivation ndeye: Kugera - Kuchenesa - 2% -3% Nitric Acid Kuti Ubvise Chiedza - Kuchenesa Chando Passivation - Kuchenesa - Kuchenesa Kukweva. Kunyanya kudziya kwekushisa panguva yekuchinja kuchaguma nekunonoka kufema firimu kuumbwa uye mutete ruvara firimu. Tembiricha yakakwira ichaita kuti firimu rive rakakura uye rakasununguka, uye kuderera hakuzove kwakasimba. Zvakanakisa kudzora zvakatenderedza makumi maviri neshanu madhigiri kuti uone kuti iwe unowana iwo mavara akafanana kwenguva yakati. Mushure mekusaruka, inoda kubikwa kuti uvandudze kuderedza uye kupokana kwefirimu.

Dachromet

DACROMET IYO RWIRY RINOGADZIRA-CORROSION DZINOGONESA NEZINC Powder, Aluminium Powder, Chromic Acid, uye Mvura Inodhonza seyakavimbika. Iyo yekufambisa inoyerera ndeye organc solvent degreasing - mechancal polising - kupfira - kubheka - kusvetuka - kubheka - kuoma.

Kubatsira kweDacromet ndiko kuti kupokana kwehutori kwakanaka kwazvo, asi kukanganisa ndiko kuti kuunganidzwa hakuna kufanana.

Sarudza yakavimbika funceners mugadziri
