Koj puas paub cov yam ntxwv ntawm cov kav dej Galvanized?

(1) Kev tsim khoom huv si tshwj xeeb
Cov yeeb nkab galvanized siv cov txheej txheem sulfate electroplating ntawm zinc-hlau alloy, uas txhais tau tias muaj cov qhov ncaj qha ntawm cov kab ntau lawm thiab cov troughs yam tsis muaj kev nqa tawm lossis dhau ntawm cov tshuaj. Txhua txheej txheem ntawm cov txheej txheem ntau lawm yog tsim los ntawm lub kaw lus ncig. Cov tshuaj hauv txhua lub tank, uas yog cov kua qaub thiab alkali, cov tshuaj electroplating, lub teeb rho tawm thiab cov tshuaj passivation, thiab lwm yam, tsuas yog rov ua dua tshiab thiab tsis xau lossis tso tawm sab nraud lub kaw lus. Cov kab ntau lawm tsuas muaj 5 lub tank ntxuav, uas siv kev ncig. Siv dua thiab tso tawm tsis tu ncua, tshwj xeeb tshaj yog hauv cov txheej txheem ntau lawm uas tsis tsim cov dej khib nyiab yam tsis tau ntxuav tom qab passivation.
(2) Qhov tshwj xeeb ntawm cov khoom siv electroplating
Kev siv electroplating ntawm cov kav dej galvanized thiab electroplating ntawm cov xov tooj liab zoo ib yam li kev siv electroplating tas mus li, tab sis cov khoom siv plating txawv. Lub tank plating yog tsim los nrog cov duab nyias nyias ntawm cov hlau hlau. Lub cev tank ntev, dav tab sis ntiav. Thaum lub sijhawm electroplating, cov hlau hlau hla dhau cov qhov thiab nthuav tawm ntawm qhov chaw kua hauv ib txoj kab ncaj, khaws qhov deb ntawm lawv. Txawm li cas los xij, cov yeeb nkab galvanized txawv ntawm cov hlau hlau vim nws muaj nws tus kheej cov yam ntxwv tshwj xeeb thiab cov khoom siv tank nyuaj dua. Lub cev tank yog tsim los ntawm cov khoom sab saud thiab sab hauv qab. Sab saud yog lub tank plating thiab sab hauv qab yog lub tank cia cov kua, tsim lub cev tank zoo li trapezoid uas nqaim ntawm sab saud thiab dav ntawm hauv qab. Muaj ib txoj kab rau kev ua haujlwm electroplating yeeb nkab galvanized hauv lub tank plating. Muaj ob lub qhov hla ntawm qab ntawm lub tank uas sib txuas lus nrog lub tank cia qis dua, thiab tsim lub kaw lus rov ua dua cov kua plating nrog lub twj tso kua dej. Yog li ntawd, cov kav dej galvanized zoo ib yam li cov hlau hlau electroplating, thiab cov khoom plated yog dynamic. Txawm li cas los xij, tsis zoo li hlau hlau plating, cov tshuaj plating rau cov kav dej galvanized kuj tseem hloov pauv tau.
(3) Kev ua kom zoo dua ntawm sulfate galvanizing
Qhov zoo ntawm sulfate galvanizing yog tias qhov ua tau zoo tam sim no siab txog li 100% thiab qhov nrawm ntawm kev tso tawm yog ceev, uas tsis muaj lwm cov txheej txheem galvanizing sib piv. Vim tias qhov crystallization ntawm lub txheej tsis zoo txaus, qhov muaj peev xwm dispersion thiab qhov muaj peev xwm plating tob tsis zoo, yog li nws tsuas yog haum rau plating cov kav dej thiab cov xov hlau nrog cov duab geometric yooj yim. Cov txheej txheem sulfate electroplating zinc-iron alloy ua kom zoo dua cov txheej txheem sulfate galvanizing ib txwm muaj. Tsuas yog cov ntsev tseem ceeb zinc sulfate khaws cia, thiab cov khoom seem raug pov tseg. Ib qho ntsev hlau tsim nyog ntxiv rau cov mis txheej txheem tshiab los tsim cov txheej txheem zinc-iron alloy los ntawm cov txheej txheem ib leeg thawj. Kev hloov kho ntawm cov txheej txheem tsis yog tsuas yog coj mus rau pem hauv ntej qhov zoo ntawm kev ua tau zoo tam sim no siab thiab qhov nrawm ntawm kev tso tawm sai ntawm cov txheej txheem thawj, tab sis kuj txhim kho qhov muaj peev xwm dispersion thiab qhov muaj peev xwm plating tob. Yav dhau los, cov khoom nyuaj tsis tuaj yeem plated, tab sis tam sim no ob qho tib si yooj yim thiab nyuaj tuaj yeem plated, thiab kev ua tau zoo tiv thaiv kuj yog 3 txog 5 npaug siab dua li cov hlau ib leeg. Kev xyaum tsim khoom tau ua pov thawj tias thaum siv rau kev siv hluav taws xob tas mus li ntawm cov xov hlau thiab cov kav dej, cov noob txheej yog cov zoo dua thiab ci dua li cov thawj, thiab qhov nrawm ntawm kev tso tawm yog ceev. Lub tuab ntawm cov txheej ncav cuag qhov xav tau hauv 2 txog 3 feeb.
(4) Kev hloov pauv ntawm sulfate zinc plating
Kev siv sulfate electroplating ntawm zinc-hlau alloy tsuas yog khaws cia zinc sulfate, cov ntsev tseem ceeb ntawm sulfate zinc plating. Cov khoom seem xws li txhuas sulfate, alum (potassium txhuas sulfate), thiab lwm yam tuaj yeem ntxiv rau hauv lub dab dej plating thaum lub sijhawm kho kom tsim cov dej hydroxide uas tsis yaj. Tshem tawm; rau cov khoom ntxiv organic, ntxiv cov hmoov carbon activated kom tshem tawm lawv los ntawm kev nqus.
Cov kev sim los ntawm cov chaw tsim cov yeeb nkab galvanized tau qhia tias txhuas sulfate thiab potassium txhuas sulfate nyuaj rau tshem tawm tag nrho ib zaug thiab muaj kev cuam tshuam rau qhov ci ntawm lub txheej, tab sis nws tsis loj heev thiab tuaj yeem coj tawm rau kev noj. Lub sijhawm no, qhov ci ntawm lub txheej tuaj yeem rov qab los ntawm kev kho nrog cov tshuaj. Ntxiv cov khoom xyaw xav tau raws li cov txheej txheem tshiab kom ua tiav kev hloov pauv.
