Aluminium die casting products surface treatment

Aluminium die casting productspamusoro kurapwa

Aluminium alloy die casting products, kurapwa kwepamusoro kazhinji: kupfapfaidza hupfu (kupfapfaidza hupfu), pendi, kupfapfaidza mafuta, oxidation, sandblasting, electroplating uye zvichingodaro. Maererano nehupamhi uye kupera kwepamusoro kurapwa kwealuminium die castingzvigadzirwa.

1, kupfapfaidza hupfu ndeyekupfapfaidza iyo poda yekuputira pamusoro peiyo workpiece nehupfu yekupfapfaidza michina. Pasi pechiito che electrostatic, hupfu huchave hwakafanana adsorbed pamusoro penzvimbo yebasa kuti iite poda coating. Upfu hwekuputira mushure mekupisa kwakanyanya kubikwa, kuenzana uye kurapa, mune akasiyana mhedzisiro (akasiyana marudzi ehupfu yekuputira mhedzisiro) yekuvhara kwekupedzisira; Kupfapfaidza poda kwakakwirira kudarika kupfapfaidza pendi musimba remagetsi, kunamatira, corrosion resistance, kuchembera kuramba uye zvimwe zvinhu, uye mutengo wayo zvakare wakaderera pane uya wekupfapfaidza pendi ine mhedzisiro yakafanana.

Kupfapfaidza hupfu, kazhinji yakakamurwa kuita hupfu hwekunze uye hupfu hwemukati. Mapeteni anogona kugadziridzwa kune akasiyana mhedzisiro, senge yakatsetseka, jecha, furo, nezvimwe.

2, iyo chaiyo yependi yekubikira maitiro ndeye kushandisa aluminium alloy phosphating mushure mekupfapfaidza, kupfapfaidza mushure mekubika, kupfeka kwakadaro hakungori anticorrosive uye kupenya kupfeka kuramba, hazvisi nyore kudonha.

Aluminium die casting products Surface pretreatment

(1) 1 kubviswa kwemafuta; 2 mvura; 3 derusting; 4 yakagezwa; 5 watch; 6 yakashambwa; 7 phosphating; 8 dzakashambidzwa; 9 dzakashambidzwa; 10 kuomesa;

Yetatu, kupfapfaidza mafuta izita reiyo yepamusoro coating process yezvigadzirwa zvemaindasitiri, mafuta ekupfapfaidza kugadzirisa kazhinji anonyanya kupfapfaidza mafuta epurasitiki, kudhinda kwescreen, pad printing process; EVA, rabha uye rumwe ruvara rweshangu, kudhinda skrini. Iine mutsara wekupfapfaidza, chidzitiro chekudhinda mutsara, pad kudhinda muchina uye zvimwe zvishandiso, uye zvinoenderana nezvinodiwa nevatengi, kugadzirwa kweyepamusoro tembiricha kuramba, friction resistance, UV resistance, alcohol resistance, peturu kuramba uye zvimwe zvigadzirwa. Kugadzirisa chiyero: zvigadzirwa zvemagetsi: zvakajairwa pfapfaidzo pendi, pendi yePU, pendi yerabha (kunzwa pendi), (senge: U dhisiki, MP3, kamera, network peripheral zvigadzirwa uye zvimwe zvigadzirwa zvemagetsi. Inogona kupfapfaidza matambudziko akaoma anowanikwa mukuumba jekiseni, semitsetse yegesi, majoini ekubatanidza, nezvimwewo, vane ruzivo mukupfapfaidza pendi yerabha (pendi yemaoko), vane tekinoroji yependi yemaoko.

4, oxidationAluminium alloy surface oxidation, yakakodzera conductive oxidation, aluminium kana aluminium profiles, yakakodzera anodic oxidation.

Aluminium alloy oxidation ruvara kazhinji yakasikwa, denga rebhuruu

1. Anodic oxidation inoitwa pasi pemamiriro ekukwirira kwepamusoro, iyo inonzi electrochemical reaction process; Conductive oxidation ndeye yakachena kemikari yekuita iyo inoda pasina magetsi asi kunyudzwa mune yemvura mhinduro. 2. Anodic oxidation inotora nguva yakareba, kazhinji maminetsi akawanda, nepo conductive oxidation inongotora masekonzi mashoma. 3. Anodic oxidation firimu ine mamicrons akati wandei kusvika kumakumi e microns, uye yakaoma uye isingapfeki, uye conductive oxidation firimu inogadzirwa chete nezve 0.01-0.15 microns. Iyo haipfeki zvakanaka, asi inoitisa magetsi uye inoramba kuparara kwemuchadenga, zvinova zvakanakira.

5, kuputika kwejecha

Kumwaya jira rejecha pamusoro pechidimbu chealuminium parts inogona kuwedzera friction coefficient yenzvimbo yekusangana uye kuwedzera kuvimbika kwekubatana. Jecha ukobvu, zviyo zvakare zvakasiyana chaizvo.

6, electroplating

Electroplating inzira iyo simbi kana alloy inoiswa pamusoro peiyo workpiece ne electrolysis kuita yunifomu, dense uye cohesive metal layer, iyo inonzi electroplating. Zvichingonzwisiswa, iko kushanduka kwemuviri nemakemikari kana kusanganiswa. Kushandiswa kwe electroplating process yatinowanzo shandisa kune zvinotevera zvinangwa: A. Anti-corrosion B. Dziviriro yekushongedza C. Kudzivirira kusakara!
