Surface Treatment

Kupedzwa kwepamusoro ndeye huwandu hwakawanda hwemaindasitiri maitiro anoshandura pamusoro pechinhu chakagadzirwa kuti uwane chimwe chivakwa. [1] Kupedzisa maitiro anogona kushandiswa ku: kunatsiridza chitarisiko, adhesion kana wettability, solderability, corrosion resistance, tarnish resistance, chemical resistance, wear resistance, kuoma, kushandura maconductivity emagetsi, kubvisa burrs nezvimwe zvinokanganisa pamusoro, uye kudzora kukwesha kwepamusoro. [2] Muzviitiko zvishoma mamwe ematekiniki aya anogona kushandiswa kudzoreredza zvimiro zvepakutanga kununura kana kugadzirisa chinhu. Nzvimbo isina kupera inowanzonzi mill finish.

Hedzino dzimwe dzedzakajairika nzira dzekurapa dzepamusoro:

Anodizing: kupfekedza simbi ine inodzivirira oxide layer. Iyo yekupedzisa inogona kuve yekushongedza, yakasimba, uye inodzivirira ngura, uye inopa nzvimbo iri nani yepende nekunamira. Aluminium ndiyo inonyanya kushandiswa simbi inodizing, asi titanium uye magnesium inogonawo kurapwa nenzira iyi. Iyo nzira ndeye electrolytic passivation process inoshandiswa kuwedzera ukobvu hweyakasikwa oxide layer pamusoro pesimbi. Anodizing inowanikwa mune akati wandei mavara.

Electroplatinginzira yekuisa chidimbu chitete cheimwe simbi kana alloy pamusoro peimwe simbi kana zvimwe zvinhu zvinoshandiswa uchishandisa electrolysis.

Physical Vapor Deposition(PVD) inoreva kushandiswa kweiyo yakaderera-voltage, yakakwira-ikozvino arc yekuburitsa tekinoroji pasi pemamiriro evacuum, kushandisa gasi kuburitsa kufambisa chinangwa uye ionize iyo vaporized zvinhu uye gasi, uchishandisa kukurumidza kwemunda wemagetsi kugadzira Iyo evaporated zvinhu. uye maitiro ayo chigadzirwa anoiswa pane workpiece.

Micro-Arc Oxidation, inozivikanwawo se micro-plasma oxidation, isanganiswa ye electrolyte uye inoenderana nemagetsi paramita. Iyo inotsamira pane pakarepo tembiricha yepamusoro uye yakanyanya kudzvanywa inogadzirwa nearc discharge pamusoro pealuminium, magnesium, titanium uye alloys ayo. Ceramic film layer.

Powder Coatingndiko kupfapfaidza upfu hwekuputira pamusoro peiyo workpiece nehupfu yekupfapfaidza mudziyo (electrostatic spray machine). Pasi pekuita kwesimba remagetsi, hupfu hunofananidzwa adsorbed pamusoro pebasa rekushanda kuti rigadzire poda yekuputira.

Kusvira Bluendeyekuzadza chitunha chese nemuvara glaze, wozobikwa muchoto chinoputika chine tembiricha yechoto inenge 800 ° C. Mucherechedzo wemuvara unonyungudutswa mumvura nejecha-sakasimba, uye mushure mekutonhora, inova ruvara rwakajeka. yakagadziriswa pachitunha. Kupenya, panguva ino, ruvara rwekupenya rwakaderera pane kureba kwewaya yemhangura, saka zvinodikanwa kuzadza iyo ruvara glaze zvakare, uyezve iyo sintered kane kana kashanu, kusvika iyo pateni yazadzwa nesiriki. thread.

Electrophoresisndiyo electrophoretic coating pane yin uye yang electrodes. Pasi pechiito chevoltage, iyo inosungirirwa coating ions inoenda kune cathode uye inodyidzana neiyo alkaline zvinhu zvinogadzirwa pamusoro peiyo cathode kuti igadzire isinganyungudika, iyo inoiswa pamusoro peiyo workpiece.

Mechanical polishinginzira yekupukuta iyo nzvimbo yakakwenenzverwa inobviswa nekucheka uye pamusoro pezvinhu zvakakanganiswa nepurasitiki kuti iwane nzvimbo yakatsetseka.

Shot Blastinginzira inotonhora yekushanda iyo inoshandisa pellet kubhomba pamusoro pechishandiso uye kuisa yakasara yekumanikidza kushushikana kuti iwedzere kuneta simba reworkpiece.

Kuputika kwejechainzira yekuchenesa uye roughening pamusoro peiyo substrate nekukanganisa kwekumhanya-mhanya kwejecha kuyerera, ndiko kuti, kushandisa mweya wakamanikidzwa sesimba rekugadzira yakakwira-speed jet beam yekupfapfaidza high-speed spray (copper ore, quartz). jecha, corundum, simbi jecha, Hainan jecha) Kumusoro kwechishandiso chinogadziriswa, chitarisiko kana chimiro chekunze kweiyo workpiece inoshanduka.

Etchinginzira inobviswa zvinhu pachishandiswa kemikari kuita kana kukanganiswa kwemuviri. Kazhinji, iyo etching inonzi photochemical etching inoreva kubviswa kwefirimu rinodzivirira redunhu kuti rigadzirwe nekugadzirwa kweplate uye kusimudzira, uye kusangana nemhinduro yemakemikari panguva yekucheka kuti iwane mhedzisiro yekuparara uye ngura, nekudaro kugadzira. mhedzisiro yekusaenzana kana kuchera.

In-Mold Decoration(IMD) inozivikanwawo setekinoroji-isina tekinoroji, tekinoroji inozivikanwa pasi rese yekushongedza pamusoro, pamusoro-yakaomeswa yakajeka firimu, yepakati yekudhinda pateni layer, yekumashure jekiseni layer, inki yepakati, iyo inogona kuita kuti chigadzirwa chirambe chichipokana. Kuti udzivise nzvimbo kuti isakwe, uye kuchengetedza ruvara rwakajeka uye kwete nyore kupera kwenguva yakareba.

Kunze Mold Decoration(OMD) inoonekwa, inobata, uye inoshanda yekubatanidza, IMD yakawedzera yekushongedza tekinoroji, ndeye 3D pamusoro pekushongedza tekinoroji inosanganisa kudhinda, manyorerwo uye simbi.

Laser engravinginonziwo laser engraving kana laser marking, inzira yekurapa kwepamusoro uchishandisa optical misimboti. Shandisa danda relaser kugadzira chiratidzo chisingaperi pamusoro pechinhu kana mukati mechinhu chakajeka.

Pad Printingndiyo imwe yedzakakosha nzira dzekudhinda, ndiko kuti, kushandisa simbi (kana mhangura, thermoplastic plastic) gravure, uchishandisa musoro wakakomberedzwa wakagadzirwa nesilicone rubber material, iyo inki iri paintaglio plate inokwizwa pamusoro pepedhi, uye ipapo pamusoro pechinhu chinodiwa chinogona kudhindwa kudhinda mavara, mapatani, nezvimwe zvakadaro.

Kudhinda Screenndeyekutambanudza jira resiririka, jira rekugadzira kana waya mesh pafuremu, uye kugadzira chidzitiro kudhinda nemaoko-pendi kana photochemical plate kugadzira. Tekinoroji yemazuva ano yekudhinda tekinoroji inoshandisa fotosensitive zvinhu kugadzira chidzitiro chekudhinda nefotolithography (kuitira kuti gomba reiyo skrini yechikamu chepikicha pane iyo skrini yekudhinda ndiro iburi, uye mesh gomba rechikamu chisiri chemufananidzo rakavharika. live). Panguva yekudhinda, iyo inki inotamirwa kune substrate kuburikidza ne mesh ye graphic chikamu ne extrusion ye squeegee kuti iite girafu yakafanana neyepakutanga.

 

Kuendesa Mvuraimhando yekudhinda umo pepa rekufambisa / firimu repurasitiki rine ruvara rwemavara rinoiswa pasi pe macromolecular hydrolysis nekumanikidzwa kwemvura. Maitiro acho anosanganisira kugadzirwa kwepepa rekudhinda rekufambisa mvura, kunyudzwa kwebepa remaruva, kufambisa maitiro, kuomesa, uye zvigadzirwa zvakapedzwa.

Powder Coatingimhando yekuputira iyo inoshandiswa seyakasununguka-inoyerera, yakaoma poda. Musiyano mukuru pakati pependi yemvura yakajairwa uye poda yekuputira ndeyekuti poda yekuputira haidi chinonyungudutsa kuchengetedza binder uye mafirita zvikamu mukuputira uye zvino inoporeswa mukupisa kuti itendere uye iite "ganda". Hupfu inogona kunge iri thermoplastic kana thermoset polymer. Inowanzo shandiswa kugadzira kupera kwakaoma kwakaoma kupfuura pendi yakajairika. Powder coating inonyanya kushandiswa kupfekedza simbi, senge midziyo yemumba, aluminium extrusions, dhiramu hardware uye mota uye zvikamu zvebhasikoro. Tekinoroji nyowani dzinobvumira zvimwe zvinhu, zvakaita seMDF (medium-density fibreboard), kuve hupfu hwakaputirwa uchishandisa nzira dzakasiyana.

Chemical Vapor Deposition(CVD) inzira yekuisa iyo inoshandiswa kugadzira yakakwira mhando, yepamusoro-inoshanda, yakasimba zvinhu, kazhinji pasi pevacuum. Maitiro acho anowanzoshandiswa muindasitiri yesemiconductor kugadzira mafirimu matete.

Electrophoretic Deposition(EPD): Chimiro chechiitiko ichi ndechekuti zvimedu zvecolloidal zvakamiswa mukati memvura yemvura zvinotama pasi pesimba remunda wemagetsi (electrophoresis) uye anoiswa pane electrode. Zvese colloidal zvimedu zvinogona kushandiswa kugadzira yakagadzikana kumiswa uye iyo inogona kutakura mubhadharo inogona kushandiswa mu electrophoretic deposition.
