Anti-corrosion ntawm galvanized steel yeeb nkab welding: Tom qab kev kho deg, tshuaj tsuag kub zinc. Yog tias galvanizing tsis tuaj yeem nyob ntawm qhov chaw, koj tuaj yeem ua raws li qhov chaw tiv thaiv corrosion: txhuam epoxy zinc-nplua nuj primer, epoxy micaceous hlau nruab nrab xim, thiab polyurethane topcoat. Lub thickness hais txog cov qauv tsim nyog.

Nta ntawm galvanized steel yeeb nkab txheej txheem
1. Kev ua kom zoo dua ntawm sulfate galvanizing: Qhov zoo ntawm sulfate galvanizing yog tias qhov kev ua haujlwm tam sim no siab li 100% thiab tus nqi tso nyiaj yog ceev, uas yog unmatched los ntawm lwm yam txheej txheem galvanizing. Vim tias cov txheej txheej crystallization tsis zoo txaus, lub peev xwm dispersion thiab sib sib zog nqus plating muaj peev xwm tsis zoo, yog li nws tsuas yog tsim rau cov kav dej electroplating thiab cov xov hlau nrog cov duab geometric yooj yim. Cov txheej txheem sulfate electroplating zinc-hlau alloy optimizes cov txheej txheem sulfate galvanizing ib txwm, khaws tsuas yog cov ntsev zinc sulfate tseem ceeb, thiab muab pov tseg rau lwm cov khoom. Nyob rau hauv cov txheej txheem tshiab, tus nqi tsim nyog ntawm hlau ntsev yog ntxiv los ua ib lub zinc-hlau alloy txheej los ntawm thawj ib txheej hlau. Lub reorganization ntawm cov txheej txheem tsis tsuas yog txhawb nqa qhov zoo ntawm cov txheej txheem qub ntawm kev ua haujlwm siab tam sim no thiab ceev deposition tus nqi tab sis kuj zoo heev txhim kho lub peev xwm dispersion thiab sib sib zog nqus plating muaj peev xwm. Yav dhau los, complex qhov chaw tsis tuaj yeem plated, tab sis tam sim no ob qho tib si yooj yim thiab complex qhov chaw tuaj yeem plated, thiab kev tiv thaiv kev ua tau zoo yog 3 mus rau 5 npaug siab dua li ntawm ib qho hlau. Kev xyaum ntau lawm tau ua pov thawj tias qhov nruam electroplating ntawm cov xov hlau thiab cov kav dej muaj cov hmoov nplej zoo dua thiab ci dua li cov qub qub, thiab tus nqi xa tawm sai. Cov txheej tuab ncav cuag qhov yuav tsum tau ua hauv 2 mus rau 3 feeb.

2. Kev hloov pauv ntawm sulfate zinc plating: Sulfate electroplating ntawm zinc-hlau alloy tsuas yog khaws cov ntsiab lus ntsev zinc sulfate ntawm sulfate zinc plating, thiab cov khoom seem xws li txhuas sulfate thiab alum (potassium aluminium sulfate) tuaj yeem ntxiv nrog sodium hydroxide thaum lub sijhawm plating tov kev kho kom tsim insoluble hydroxide nag lossis daus rau kev tshem tawm; rau cov organic additives, hmoov activated carbon yog ntxiv rau adsorption thiab tshem tawm. Qhov kev ntsuam xyuas qhia tau hais tias aluminium sulfate thiab potassium aluminium sulfate yog qhov nyuaj rau tshem tawm tag nrho ntawm ib zaug, uas muaj kev cuam tshuam rau lub ci ci ntawm txheej, tab sis nws tsis loj heev thiab tuaj yeem noj nrog kev tshem tawm. Lub sijhawm no, qhov ci ntsa iab ntawm txheej tuaj yeem rov qab los. Cov tshuaj tuaj yeem muab ntxiv raws li cov ntsiab lus ntawm cov khoom uas yuav tsum tau ua los ntawm cov txheej txheem tshiab tom qab kev kho mob, thiab kev hloov pauv tiav.

3. Ceev ceev deposition npaum li cas thiab zoo heev tiv thaiv kev ua tau zoo: Tam sim no efficiency ntawm sulfate electroplating zinc-hlau alloy txheej txheem yog siab li 100%, thiab ceev deposition tus nqi yog unmatched los ntawm tej txheej txheem galvanizing. Kev khiav ceev ntawm lub raj zoo yog 8-12m / min, thiab qhov nruab nrab txheej thickness yog 2m / min, uas yog ib qho nyuaj rau ua tiav nrog nruam galvanizing. Cov txheej yog ci, muag heev, thiab txaus siab rau qhov muag. Raws li lub teb chaws tus qauv GB / T10125 "Artificial Atmosphere Test-Salt Spray Test" txoj kev, cov txheej txheem tsis zoo thiab tsis hloov pauv rau 72 teev; ib qho me me ntawm cov xeb dawb tshwm rau saum npoo ntawm txheej tom qab 96 teev.

4. Cov khoom huv huv tshwj xeeb: Cov yeeb nkab steel galvanized txais cov txheej txheem sulfate electroplating zinc-hlau alloy, uas txhais tau hais tias cov kab ntau lawm yog perforated ncaj qha thiab cov tshuaj tsis tau nqa tawm lossis dhau mus. Txhua tus txheej txheem ntawm cov txheej txheem ntau lawm muaj ib txoj kev ncig. Cov kev daws teeb meem ntawm txhua lub tank, uas yog cov kua qaub thiab alkali, cov tshuaj electroplating, thiab lub teeb thiab passivation tov, tsuas yog siv dua thiab rov siv dua yam tsis muaj dej los yog tawm mus rau sab nraud. Cov kab ntau lawm tsuas muaj 5 lub tso tsheb hlau luam tu, uas yog siv thiab rov siv dua tsis tu ncua, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem ntau lawm yam tsis muaj dej khib nyiab tom qab passivation.

5. Qhov tshwj xeeb ntawm cov khoom siv electroplating: Cov electroplating ntawm galvanized steel kav yog tib yam li cov electroplating ntawm tooj liab hlau, uas yog ob qho tib si txuas ntxiv electroplating, tab sis cov khoom siv plating yog txawv. Lub plating tank tsim rau txoj hlua khi cov yam ntxwv ntawm cov hlau hlau yog ntev thiab dav tab sis ntiav. Thaum lub sij hawm electroplating, cov hlau hlau hla dhau ntawm lub qhov thiab kis tawm ntawm cov kua saum npoo ntawm ib txoj kab ncaj nraim, tswj kev deb ntawm ib leeg. Txawm li cas los xij, galvanized steel kav yog txawv ntawm cov hlau hlau thiab muaj lawv cov yam ntxwv tshwj xeeb. Cov khoom siv tank yog qhov nyuaj dua. Lub tank lub cev yog tsim los ntawm sab sauv thiab qis. Lub sab sauv yog lub plating tank, thiab qhov qis dua yog cov kev daws teeb meem ntawm lub tank, tsim lub cev trapezoidal uas nqaim rau saum thiab dav hauv qab. Muaj cov channel rau electroplating ntawm galvanized steel kav hauv lub plating tank. Muaj ob qhov los ntawm qhov nyob hauv qab ntawm lub tank uas txuas nrog lub tank cia hauv qab, thiab tsim cov txheej txheem plating thiab rov siv dua nrog lub twj tso kua mis submersible. Yog li ntawd, lub plating ntawm galvanized steel kav yog dynamic, ib yam li cov electroplating ntawm hlau nyob ntawm tej. Tsis zoo li electroplating ntawm cov hlau hlau, cov tshuaj plating ntawm electroplated galvanized steel kav kuj tseem muaj zog.
