Njengoba sonke sazi, i-potassium chloride ne-zinc chloride amasawoti ayinhloko esixazululo se-zinc acid plating. Ngakho-ke sisilawula kanjani isilinganiso sokuhlushwa se-potassium chloride ne-zinc chloride ebhavini lapho sintula izimo zokuhlaziya enqubweni yokukhiqiza yokusebenzisa izithako ze-acid zinc plating?
Ngokokuhlangenwe nakho kwesayithi nezici ye-BZ-528, i-i-acid zinc plating additive, i-Bigley Technology ihlaziye lezi zinyathelo ezintathu ezilandelayo:
1. Indlela yokuminyana. Kusisombululo se-zinc acid plating, ukugcwala kwe-potassium chloride kungu-180 ~ 220g/L, okungaphezulu kakhulu kokuhlushwa kwe-zinc chloride ne-boric acid. Ngakho-ke, singasungula indlela yokulawula i-potassium chloride njengosawoti oyinhloko, okungukuthi, sebenzisa imitha yokuminyana enobubanzi obungu-1.10 ~ 1.20 ukukala ukuminyana kwesisombululo sokucwenga, nokulawula ukuminyana kwesisombululo sokucwenga phakathi kuka-1.16~ 1.20. Lapho ukuminyana kwesisombululo se-plating kungaphansi kuka-1.16, ukuhlushwa kwesisombululo sokucwenga akwanele, futhi i-potassium chloride, i-zinc chloride ne-boric acid idinga ukungezwa; Uma ukuminyana kwesisombululo sokucwenga kungaphezulu kuka-1.20, ukugxila kwesisombululo sokucwenga kuphezulu kakhulu futhi kudinga ukuhlanjululwa ngamanzi.
2. Indlela yokwengeza isikali. Ngenxa yokuthi isilinganiso sokuhlushwa se-zinc chloride ne-potassium chloride esixazululweni sokucwenga singaba ngu-3: 1, i-zinc chloride ne-potassium chloride ekhishwa ku-workpiece futhi ihlungiwe ngesikhathi sokukhiqiza nayo iyasetshenziswa ngokwalesi silinganiso. Ukuze silondoloze ibhalansi yesilinganiso sazo, singakwazi ukwengeza i-potassium chloride ne-zinc chloride ngokwalesi silinganiso. Ngisho noma kukhona ukuchezuka kwengxenye esixazululweni sokucwenga, ukuchezuka kungancishiswa ngokungeza i-potassium chloride ne-zinc chloride ngokwale ngxenye.
3. Indlela ye-Hull groove. Nakuba indlela yokuminyana kanye nendlela yokulinganisa ingagcina ukuqina kwesisombululo sokucwenga isikhathi eside enqubweni yokukhiqiza, isilinganiso sokuhlushwa se-potassium chloride ne-zinc chloride esixazululweni sokucwenga sizoba nokuphambuka okuthile. Ngakho-ke, kuyadingeka ukwenza njalo ukuhlolwa kweseli ye-Hull noma ukuhlolwa kweseli elincane ekhambi lokucwenga ukuze kuqinisekiswe isimo sesisombululo sokucwenga futhi wenze izinguquko.
Ngakho-ke, ngaphandle kwezimo zokuhlaziya inqubo yokukhiqiza yokusebenzisa i-asidi zinc. Plating izithasiselo, singakwazi ukulawula isilinganiso sokuhlushwa potassium chloride kanye zinc chloride okugeza ngokuvumelana ngenhla izinyathelo ezintathu ukugcina ukuzinza okugeza. Uma unentshisekelo ku-izithako ze-acid zinc plating, sicela uxhumane no-Bigley customer service ukuze uthole amasampula amahhala kanye nolwazi oluningiliziwe lobuchwepheshe!
Uma ufuna ukwazi okwengeziwe mayelana nokufaka ama-galvanizing, ungachofoza ukuze ubuke i-Electroplating Encyclopedia.
