Sei zinc alloy kufa-yekukanda vagadziri kugadzirisa mweya Bub Bubb？

Zinc alloy ialloy inoumbwa ne zinc yakawedzerwa nezvimwe zvinhu. Zinc alloys ari nyore kuumba, ane purasitiki yakasimba, mutengo wakaderera, hukuru hwekugadzirisa, uye huwandu hwakawanda hwekushandisa. Nekudaro, iwo matambudziko ekupupa (electroplating uye kupfapfaidza) eJiangmen zinc alloy die castings mamwe matambudziko. Saka sei kugadzirisa chikonzero blistering? Mapoinzi anotevera:

1. Chigadzirwa dhizaini

Kana dhizaini yezinc alloy die-casting zvigadzirwa zvatanga, zvinodikanwa kuti utarise chiteshi chekudyisa, slag discharge port uye exhaust kumisikidza yekufa-casting mold. Nokuti nzira inoyerera ye workpiece yekudyisa uye slagging yakatsetseka, hapana mhepo inopindira, hapana mavara emvura, uye hapana rima mabhubhu, izvo zvinokanganisa zvakananga kana inotevera electroplating blisters. Akakodzera kudya uye slagging. Iyo mold inofa-yakakandwa. , Hapana mavara emvura.

 2. Kuvandudzwa kwekufa kukandira mold

Mukugadzirwa kwemafa-casting molds, iyo tonnage, kudzvanywa, kusakwana kudzvanywa, uye kushomeka kwekupera kwemuchina wekuumbwa kunofanirwawo kutariswa. Hazvina mhosva kuti kusati kwaitwa kurapwa kweplating kunogadziriswa sei, pane nguva dzose 20-30% inoputika. Iyo mold yakavharwa uye yakachinjirwa kuita maPiece mashoma, hapana kubhuroka zvakare mushure mekuputirwa.

3. Pre-kurapwa kwepamusoro

Iyo pre-kurapwa pamusoro pemvura yekupukuta, yekupuruzira paste, uye oxide layer haina kucheneswa, uye kazhinji inokunguruka. Iyo zinc alloy die-casting mushure mekukunguruka inopenya. Vazhinji vashandi vari mu electroplating chirimwa pickling process inotorwa zvisina tsarukano. Iyo polishing agent yakanamirwa pamusoro haina kushambidzwa, uye blistering inowanzoitika. Mukuwedzera, iyo calender inoshandiswa necalendering uye polishing plant inewo hukama hukuru, uye mamwe ma surfactants mu calender anonetsa kushambidza.

4. Kana chigadzirwa chinopinda alkali mhangura

Chigadzirwa chisati chapinda mu alkali copper plating tangi, zinc alloy die-casting parts zvichine firimu dema risina kubatwa ne oxide film kubvisa wakisi nemafuta. Nokudaro, kubviswa kwe membrane kunokosha zvikuru. Mumakore ekutanga, inogona kubviswa nekushandisa anti-staining munyu. Ikozvino kudzivirira kwezvakatipoteredza hakubvumiri kubuda kwemvura yakasvibiswa ine anti-staining munyu.

5. Alkali copper plating tank

Kune akawanda organic zvinhu mu alkaline copper plating tangi, uye kune akawanda tsvina, uye yemahara cyanide haisi muhuwandu. Edza zvinongedzo zvealkaline mhangura tangi kuti uone kana sodium cyanide yakaderera kana iyo sodium hydroxide yakakwira! Zvakanyanya kukosha, zvinokurudzirwa kubata kabhoni kamwe chete mazuva 3-5.

6. Conductivity yealkali copper cylinder

Iko conductivity yealkaline copper cylinder yakakoshawo. Kunyangwe iyo anode yakanyungudutswa nemazvo uye anode yemhangura ndiro yakakwana zvinozotungamira mukupupuma.

7. Chigadzirwa chacho chinoputika mushure mekubuda muchoto

Inogona kukonzerwa nekushisa kusina kuenzana kwevheni, ndiko kuti, kutonhora kwakanyanya. Nekuda kwekushaikwa kwekusimba panguva yekukanda kufa, zviri nyore kuti asidhi ipinde mumvura yakasvibiswa trachoma ye zinc alloy die castings. Iyo asidhi uye zinc zvicharamba zvichibata makemikari kunyange kana paine pamusoro pekuvhara, ichigadzira huwandu hwakawanda hwehydrogen H. . Kana kudzvanywa kwemukati kwakakwira kupfuura kudzvanywa kwemhepo Kusvika kumwero wakati, kuwedzera tembiricha yepamusoro kunoburitsa mabhuru.
