Surface kurapwa nzira uye maitiro emhangura bar copper chubhu

1. Pendi iyomhangura bar
Iri hunyanzvi nderekubvisa hunyanzvi hwekudzokera kumashure, hachiwanzo shandiswa izvozvi. Maitiro: Matatu-chikamu AC redunhu bhazi richapendwa nependi nhema, uye kodhi kodhi ichanamirwa munzvimbo dzinoonekwa. Chikamu A chichava yero, chikamu B chichave chegirini, uye chikamu C chichava chitsvuku. Mutsetse usina kwawakarerekera kana mutsara usina kwawakarerekera uchapendwa nependi yeblue.
2. Tin plating pabhawa remhangura
Zvakanakira: muitiro mukuru. Short operation cycle, inowanzoshandiswa. Kushaya simba: kureba kwenguva yakareba bvudzi rakasviba, maoko haakwanisi kuita. Kwete kudzivirira kwezvakatipoteredza!
Kuyerera kwemaitiro: kupenya kwepamusoro, kubviswa kwemafuta uye kumwe kugadzirwa → kugeza mvura yakachena → kuputira yakakwira Pb-Sn alloy tepi yekugeza mvura → kugeza mvura yakachena → tin plateting → pombi yemvura yekupfapfaidza yekugeza → neutralization (Na2HPO4+Na3PO4)→ tepi mvura yekupfapfaidza yekugeza → dip stearic mvura yekupfapfaidza → dhibha mvura yemvura yakachena → kugeza mvura yakaomeswa → tap washing mvura yekugeza.
3. Bhara remhangura rakaputirwa nemumiririri wekudzivirira
Mabhenefiti: kuchengetedza iyo copper bar primary color, yakaderera zvishoma pane mutengo wetin plating. Zvakaipa: Kutenderera kwenguva refu kwekushanda.
Kuyerera kwemaitiro: kupukuta kusati kwarapwa → kugeza mvura yakachena → pickling passivation workpiece → kuomesa hunyoro →JLR-510 kudzivirira kurapwa → inoyerera mvura yekuchenesa → kunyudzwa nemvura inopisa (inenge 100 ℃, kushandiswa kupisa workpiece, chinangwa chekubuda kwemvura kana kuomesa) → kuomesa → kurongedza kuvharwa.
Pipe yemhangura otomatiki inomonereka uye mutsara wekusunungura inoratidzirwa mukuti inosanganisira mudziyo unomonereka, mudziyo unotsigira, mudziyo wekuchenesa, mudziyo wekuyera uye mudziyo unomonereka unoiswa zvakatevedzana uchitevedza nzira yekufamba yepombi yemhangura mukuita mhepo nekusunungura. Imomo, mudziyo wekusunungura, mudziyo wekusunungura wechubhu yekuvhura yemhangura; Copper chubhu inotsigira mudziyo, mudziyo wekutsigira unoshandiswa kutsigira yekusunungura mudziyo mushure mekusunungura chubhu yemhangura;
