Yakatumirwa pa 2016-06-22 Zinc flake coating Irudzi rutsva rwekupotera kwekupotera, yave kushandiswa zvakanyanya, zinc flake coating process kunyanya ndiyo base zvinhu, degreasing, derusting, coating, preheating, kurapa, kutonhora.
1. Degreasing: workpiece pamusoro inofanira kunge yakasvibiswa, kazhinji ine nzira nhatu: organic solvent degreasing, mvura-based degreasing agent, high temperature carbonization degreasing.Kuti degreasing inonyatsoshanda, ichakanganisa zvakananga kunamatira kwekuputira.
2. Derusting uye deburring: workpiece pamwe ngura kana Burr vanonyatsorambidzwa yakananga unhani, anofanira kupfuura derusting uye deburring muitiro, muitiro uyu akanga nani kushandisa michina nzira, kudzivisa asidhi kudzivirira hydrogen embrittlement.
3. Coating: workpiece pashure degreasing uye derusting inofanira kunyura, kumwaya kana kukwesha nokukurumidza.
4. Pre-kupisa: workpiece ne zinc flake coating pendi pamusoro pepamusoro anofanira pre-kupisa 10-15 maminitsi ASAP pasi tembiricha 120 + 20 ℃, kuita unhani mvura mvura evaporation.
5. Kurapa: workpieces pashure pre-kupisa anofanira kurapa pasi 300 ℃ yakakwirira tembiricha, kurapa nguva 20-40 maminitsi, uyewo anogona zvakakodzera kusimudza tembiricha kupfupisa kurapa nguva.
6. Kutonhodza: Zvishandiso mushure mekurapa zvinofanirwa kutonhodzwa zvakazara nekutonhodza sisitimu yekugadziridza kana kupedzwa kwekuongorora zvinhu.
