E ngotsoe ka 2016-06-22 Zinc flake coating Ke mofuta o mocha oa koae ea ho hanyetsa kutu, e se e sebelisoa haholo, ts'ebetso ea ho roala li-zinc flake haholo-holo ke lisebelisoa tsa motheo, ho hloekisoa, ho senya, ho roala, ho futhumatsa pele, ho phekola, ho pholile.
1. Degreasing: workpiece holim'a lokela ho degreased, ka kakaretso e na le litsela tse tharo: manyolo solvent degreasing, metsi-based degreasing moemeli, phahameng mocheso carbonization degreasing.Whether degreasing ka ho phethahetseng atlehang, tla ka ho toba ama adhesion tsa barbotage.
2. Derusting le deburring: workpiece le mafome kapa burr ba ka tieo thibetsoe ka ho toba barbotage, lokela ho feta derusting le deburring tshebetso, tshebetso ena ne ho molemo ho sebelisa mokhoa oa mechine, qoba acid e ho thibela embrittlement haedrojene.
3. Coating: workpiece ka mor'a degreasing le derusting lokela ho qoela, fafatsa kapa borashe kapele.
4. Pre-heating: workpiece le zinki flake barbotage pente ka holim'a metsi lokela ho pele ho futhumatsa metsotso e 10-15 kapele tlas'a mocheso oa 120 + 20 ℃, ho etsa barbotage mokelikeli metsi e mouoane.
5. Ho phekola: workpieces ka mor'a ho futhumatsa pele ho lokela ho phekola tlas'a 300 ℃ mocheso o phahameng, nako ea ho phekola metsotso e 20-40, e ka boela ea phahamisa mocheso ka nepo ho khutsufatsa nako ea ho folisa.
6. Cooling: Lisebelisoa ka mor'a ho folisoa li tlameha ho pholile ka ho feletseng ka mokhoa oa ho pholisa bakeng sa ho tsosolosa kapa ho hlahloba thepa e felileng.
