Xakamaynta tayada ee daahan weyn oo duudduuban galvanized silig

1. Hagaajin cabbirada habka korantada

Si adag u xakamee qiimaha pH ee duubka weynsilig galvanizedqubeyska, cilmi baaris ayaa muujinaysa in size ee qiimaha pH qubeyska si toos ah u saameeyaa tayada daahan silig birta, kontoroolka aan habboonayn ee qiimaha pH keeni doonaa daahan dabacsan.Marka qiimaha pH uu ka weyn yahay 3, dahaarka siliga birta ayaa leh burr ay sababto dendrites ganaax ah, oogadana ma fududa.Cufnaanta hadda si adag ayaa loo xakameeyaa.Laga soo bilaabo qaab-dhismeedka microscopic-ka, cufnaanta hadda jirta, way sii weynaataa kaydinta lakabka zinc, cufan yar oo u dhiganta lakabka zinc.

Taas bedelkeeda, cufanka ion-ku-dhigista, ayaa ka sii fiicnaanaya tayada lakabka zinc.Marka la eego xaalada in lakabka zinc dushiisa uu yahay mid cufan oo dhalaalaya, tayada lakabka zinc halkii unug waa in ay gaaraan 80g / m2, iyo cabbirada habka waa in la hagaajiyaa sida soo socota: cufnaanta hadda waa 16-20A / dm2, xoojinta xajmiga zinc Xalka sulfate waa 500g/L, pH qiimaha waa 2.5-3.0.

2. Hagaajin habka sawirka ee haanta biyaha

Iyadoo si adag loo raacayo sawirka cabbirka cadaadiska yar-yar ee baasaska badan, wadarta guud ee cadaadiska waa 96.48%, taasoo yaraynaysa xoqitaanka lakabka zinc.Dhimashada siliga oo dhan waxay ka samaysan tahay dhinta birta tungsten iyo dhinta polycrystalline.Xagasha koorta shaqada ee sawir gacmeedku waa 12 ° ~ 16 °, dhererka suunka cabbirkuna waa 0.15 dhexroorka fiilada, si loo hubiyo in qallafsanaanta lakabka zinc uu asal ahaan la mid yahay substrate silig bir ah.

Nidaamka wareegga qaboojinta wuxuu isticmaalaa buufin si uu u qaboojiyo dhinta sawirka, wuxuuna ka qaadaa kulayl badan oo ay dhaliso mashiinka sawir-qaadista ee sawirka xawaaraha sare leh ee waqtiga si loo hubiyo tayada fiilada.Xakamaynta cabbirrada habka sawirka: xawaaraha sawirka 10 ~ 12m / s;Xiisadda dabaysha 8 ~ 10N;Dhererka cabbirka 30km;Qeybta guud ee saliidaha waa 3.5 ~ 4.5%;Qiimaha pH ee saliidda 7 ~ 8;Heerkulka saliidda 30 ~ 40 ℃.

Ka dib hagaajinta habka, wax soo saarka ballaaran ee 0.80mm electrosilig bir galvanizedtayada lakabka zinc electro galvanized waxaa lagu xakameeyaa gudahood 80 ~ 90g / m2, kala firidhsan tayada lakabka zinc waa mid aad u yar;Natiijooyinku waxay muujinayaan in celceliska culeyska lakabka zinc uu yahay 14.5g/m2, luminta lakabka zinc wuxuu ka yar yahay 5%, iyo xoogga xajinta ee siliga birta waa 2300 ~ 2500MPa.Ma aha oo kaliya inay si wax ku ool ah u maamusho tayada lakabka zinc ee fiilada birta ceeriin, laakiin sidoo kale waxay yaraynaysaa qashinka aan loo baahnayn iyo kharashka wax soo saarka.
