Adalemba pa 2016-06-22 Kupaka kwa Zinc flake Ndi mtundu watsopano wa zokutira zokana dzimbiri, zakhala zikugwiritsidwa ntchito kwambiri, njira yokutira ya zinc flake makamaka ndizoyambira, kutsitsa, kuwononga, kupaka, kutenthetsa, kuchiritsa, kuziziritsa.
1. Degreasing: workpiece pamwamba ayenera degreased, zambiri ali njira zitatu: organic zosungunulira degreasing, madzi ofotokoza degreasing wothandizila, mkulu kutentha carbonization degreasing.Ngakhale degreasing bwinobwino ogwira, zidzakhudza mwachindunji adhesion wa ❖ kuyanika.
2. Derusting ndi deburring: workpiece ndi dzimbiri kapena burr ndi mosamalitsa analetsa mwachindunji ❖ kuyanika, ayenera pochitika derusting ndi deburring ndondomeko, ndondomeko anali bwino ntchito makina njira, kupewa asidi kupewa hydrogen embrittlement.
3. zokutira:workpiece pambuyo degreasing ndi derusting ayenera kuviika, kupopera mbewu mankhwalawa kapena brushing mwamsanga.
4. Pre-Kutentha: workpiece ndi nthaka flake ℃ ℃ ℃ utoto ℃ ayenera Pre-Kutentha 10-15 Mphindi mwamsanga pansi pa kutentha kwa 120 + 20 ℃, kuti ℃ ℃ ℃ ℃ ℃ ℃ ℃ ℃ ℃ ℃ ℃ ℃.
5. Kuchiritsa: workpieces pambuyo Kutentha chisanadze ayenera kuchiritsa pansi 300 ℃ kutentha, kuchiritsa nthawi 20-40 mphindi, komanso akhoza moyenerera kukweza kutentha kufupikitsa kuchiritsa nthawi.
6. Kuziziritsa: Zida zogwirira ntchito zikatha kuchiritsa ziyenera kuzizidwa bwino ndi makina ozizirira kuti akonzenso kapena kuyang'anitsitsa katundu.
