Fa'asalalau ile 2016-06-22 Zinc flake coating O se ituaiga fou o le corrosion resistance coating, ua faʻaaogaina lautele, zinc flake coating process e masani lava o le mea faavae, degreasing, derusting, coating, preheating, curing, cooling.
1. Degreasing: workpiece luga e tatau ona degreased, e masani lava e tolu auala: soli solvent degreasing, vai-faavae degreasing sui, maualuga vevela carbonization degreasing.Whether degreasing lelei atoatoa, o le a aafia tuusao le pipii o le ufiufi.
2. Derusting ma deburring: o le mea faigaluega ma ele po burr ua matua faasaina le ufiufi tuusao, e tatau ona pasia le derusting ma deburring faagasologa, o lenei faagasologa sa sili atu le faaaogaina o auala masini, aloese mai le acid e puipuia ai le hydrogen embrittlement.
3. Ufiufi: mea faigaluega ina ua uma degreasing ma derusting e tatau ona fufui, fufulu pe fufulu asap.
4. Fa'avevelaina muamua: mea faigaluega fa'atasi ma le zinc flake coating vali i luga e tatau ona mua'i fa'avevela 10-15 minute asap i lalo ole vevela o le 120 + 20 ℃, e fa'alava ai le vai vai.
5. Fa'amālōlōina: mea faigaluega pe a mae'a fa'avevela e tatau ona fa'amalo i lalo ole 300 ℃ maualuga le vevela, fa'amalolo taimi 20-40 minute, e mafai fo'i ona fa'ae'e lelei le vevela e fa'apu'upu'u taimi fa'amalolo.
6. Fa'alili: Mea faigaluega pe a uma ona fa'amalo e tatau ona fa'amalo atoatoa e ala ile faiga fa'amafanafana mo le toe gaosia po'o le siakiina o oloa mae'a.
