Kub-dip galvanized steel kav yog galvanized kav ua los ntawm immersing steel kav nyob rau hauv molten kua hlau zinc los yog nws alloys. Cov txheej txheem tshwj xeeb suav nrog alkali ntxuav, pickling, rinsing, dipping pab, ziab, thiab kub-dip galvanizing. , sab nraud tshuab, rub tawm, sab hauv tshuab, dej txias, passivation, tshuaj xyuas, thiab lwm yam. Lub ntsiab zoo ntawm cov kav dej kub-dip galvanized yog cov nqi ua haujlwm tsawg, durability, zoo kev ntseeg siab, muaj zog toughness ntawm txheej, txuag lub sij hawm thiab kev siv zog, tsawg. tus nqi pib, thiab kev tshuaj xyuas yooj yim. Cia peb saib cov txheej txheem tsim khoom ntawm kub-dip galvanized steel kav.
Cov txheej txheem ntau lawm ntawm kub-dip galvanized steel yeeb nkab
Kub-dip galvanized steel yeeb nkab, tseem hu ua kub-dip galvanized yeeb nkab, yog cov yeeb nkab steel uas yog galvanized ntawm cov kav hlau dav dav los txhim kho nws cov kev ua tau zoo. Lub hauv paus ntsiab lus ntawm nws cov kev ua thiab kev tsim khoom yog los ua cov hlau molten nrog cov hlau matrix los tsim cov txheej txheem alloy, yog li ua rau cov matrix thiab Plating ua ke ob qho tib si. Yog li cas yog kub-dip galvanized steel yeeb nkab ua tiav? Cov txheej txheem ntws ntawm kub-dip galvanized steel yeeb nkab tau muab faib ua cov kauj ruam hauv qab no:
1. Alkali tu: Qee cov kav hlau steel muaj cov roj stains ntawm lawv qhov chaw thiab yuav tsum tau ntxuav alkaline.
2. Pickling: Siv hydrochloric acid rau pickling kom tshem tawm cov oxide nplai ntawm cov yeeb nkab steel.
3. Rinsing: Feem ntau yog tshem tawm cov residual acid thiab hlau ntsev txuas rau saum npoo ntawm cov yeeb nkab steel.
4. Dip aid: Lub luag haujlwm ntawm flux yog tshem tawm tag nrho cov impurities ntawm qhov chaw ntawm cov yeeb nkab steel, xyuas kom huv si ntawm cov yeeb nkab steel thiab cov kua zinc, thiab tsim cov txheej txheem zoo.
5. Kev ziab: feem ntau yog tiv thaiv cov yeeb nkab steel los ntawm kev nkag mus rau hauv lub lauj kaub zinc thiab ua rau blasting.
6. Kub-dip galvanizing: Qhov kub ntawm cov kua zinc hauv lub lauj kaub zinc yog nruj me ntsis tswj ntawm 450 ± 5 degree. Muab cov yeeb nkab steel rau hauv lub qhov cub galvanizing thiab yob nws mus rau hauv peb lub galvanizing spirals hauv lub tshuab galvanizing. Peb lub spirals muaj cov theem sib txawv. Cov yeeb nkab steel ua inclined rau ntawm kauv. Raws li cov kauv rotates, cov yeeb nkab steel txav mus rau hauv qab los tsim lub kaum sab xis, ces nkag mus rau hauv cov kua zinc, txuas ntxiv mus rau hauv qab, thiab cia li poob rau ntawm txoj kab swb hauv lub lauj kaub zinc; tos kom txog thaum cov yeeb nkab steel yog lifted mus rau cov hlau nplaum Thaum cov menyuam nto dov, nws yuav raug nqus thiab txav mus rau lub rooj rub tawm.
7. Sab nraud tshuab: Cov yeeb nkab steel hla dhau lub nplhaib tshuab sab nraud thiab compresses cua kom tshuab tawm cov kua zinc ntau dhau los ntawm cov yeeb nkab steel kom tau qhov chaw du.
8. Drag tawm: Tsim nyog txo qhov rub tawm nrawm los tswj cov nyiaj zinc thiab txo cov zinc noj.
9. Sab hauv tshuab: tshem tawm cov kua zinc ntau dhau ntawm cov yeeb nkab steel sab hauv kom tau txais ib qho zoo nkauj sab hauv. Cov kua zinc tshem tawm ua cov zinc hmoov rau rov ua dua.
10. Dej txias: Qhov kub ntawm cov dej txias tank yog tswj ntawm 80 degree, thiab cov yeeb nkab galvanized yog txias.
11. Passivation: Passivation kua yog txau thiab tshuab rau hauv cov yeeb nkab tiav kom passivate saum npoo ntawm cov yeeb nkab. Tom qab tshuab los ntawm lub nplhaib sab nraud, cov kua passivation ntau dhau yog tshuab nrog cua compressed.
12. Kev tshuaj xyuas: Cov yeeb nkab steel galvanized ntog ntawm lub rooj zaum tshuaj xyuas. Tom qab kev soj ntsuam, cov xaim galvanized yeeb nkab yog muab tso rau hauv lub pob tawb pov tseg, thiab cov yeeb nkab tiav tau ntim thiab khaws cia rau hauv lub warehouse.
