Cov txheej txheem ntawm cov kav dej galvanized suav nrog kev ua ntej, electroplating thiab post-processing. Qhov cuam tshuam ntawm cov txheej txheem electroplating ntawm qhov zoo ntawm plating kuj cuam tshuam los ntawm ntau yam hauv cov txheej txheem electroplating thiab cov ntaub ntawv. Summed rau rau yam.
1. Zinc: Zinc thiab zinc blocks muaj siab purity thiab nqaim lub teeb. Tsheb steel daim hlau yooj yim dua kom tau cov txheej tuab nrog cov ntsiab lus hlau qis. Thaum lub purity ntawm zinc block tsawg dhau lawm, lub teeb yuav loj dua, thiab cov tuab ntawm zinc txheej hauv cov kev cai yuav ntev dua, uas ua rau cov ntsiab lus hlau ntau hauv zinc txheej.
2. Muaj ob qhov teebmeem ntawm sodium hydroxide thiab sodium hydroxide. Thaum cov ntsiab lus ntawm sodium hydroxide siab dhau lawm, cov txheej txheem kev ua haujlwm ntawm qhov kub thiab txias tuaj yeem tshwm sim. Thaum cov ntsiab lus ntawm sodium hydroxide tsawg dhau thiab cov tshuaj tsis raug kho, cov txheej txheem yuav txo qis.
3. Cov ntsiab lus hlau: Thaum cov ntsiab lus hlau siab dhau lawm, cov ntsiab lus hlau hauv cov txheej txheem yuav tsim nyog dua, thiab qhov ci ci ntawm passivation thiab cov khoom tsis muaj; Cov ntsiab lus tsis tshua muaj hlau yuav ua rau cov ntsiab lus tsis tshua muaj hlau nyob rau hauv zinc txheej, corrosion kuj ntawm lub rooj tsav tsheb lub rooj tsavxwm, thiab ua rau lub rooj tsav tsheb lub rooj tsav tsheb muaj kev tiv thaiv corrosion, thiab ua rau lub rooj tsav tsheb muaj kev tiv thaiv corrosion, thiab ua rau lub rooj tsav tsheb corrosion kuj thiab ua rau lub tsheb daim hlau. tsis kam thiab ua rau lub tsheb boards thiab ua rau lub tsheb board kuj thiab ua rau lub tsheb daim hlau tsis kam thiab ua rau lub tsheb phaj. Qhov saum npoo ntawm lub tsheb tsim polystumin. Torion
4. Polishing: Tam sim no ntau lub teeb sib xyaw los ntawm ZF-100A thiab ZF-100B. Cov concentration ntau dhau yuav ua rau kom lub nkig ntawm cov txheej. Tsawg dhau yuav ua rau thaj tsam qis tam sim no txheej yog qhov tsawg thiab tsis muaj kev mob siab rau.
5. Qhov kub thiab txias yuav txo tau qhov kev so ntawm cov txheej txheem kev kho cov kua plating, nce cov ntsiab lus hlau ntawm cov txheej txheej plating, thiab tsis sib xws passivation; thaum cov tshuaj tiv thaiv kub qis, qhov siab-tam sim no ntom ntom ntawm qhov kub hnyiab hauv lub sijhawm luv. siab. Ua rau qeeb qeeb.
6. Cathode txav ceev: Nws yog ib qho tsim nyog los xyuas kom meej tias cov txheej txheem cathode plating nyob rau hauv lub xeev ntawm kev txav. Yog hais tias lub zog txav ceev heev, cov txheej txheem plating nyob rau hauv qhov chaw siab tam sim no yuav ntxhib; Yog tias qhov kev txav nrawm dhau qeeb, cov ntaub ntawv ntws yuav raug tsim, thiab txheej txheej plating tsis sib npaug.
Galvanized yeeb nkab rau galvanized hlau. Lawv yog cov electrolytic nyob rau hauv cov tshuaj zinc, thiab ces tso rau ntawm qhov chaw ntawm lub raj los tsim ib tug square, uniform, nplua-galvanized hlau txheej. Piv nrog rau lwm yam hlau, zinc yog ib tug poj niam txiv neej hlau uas yooj yim yaj nyob rau hauv acid thiab alkali, thiab yog yooj yim electrolytic los ntawm hlau ions nyob rau hauv cov tshuaj. Thaum lub sij hawm ua cov galvanized square kav, cov saum toj no yam yuav tsum tau txiav txim siab nyob rau hauv thiaj li yuav tsim tsim nyog galvanized galvanized yeeb nkab khoom.
