Kev tsim cov txheej txheem rau Wrought Hlau Fencing

Txiav → Forging → Ornamental Bending → Vuam & Sib dhos → Sib tsoo → Kub-dip Galvanizing → Polishing → Txau xim → Cub ci → Kho kom zoo nkauj tiav txheej → Clear Coat Application → Ntim. Anti-kev kho xeb thiab txheej txheem ntws rau wrought hlau railings: Kub-dip galvanizing yog qhov zoo tshaj plaws thiab siv tau los tiv thaiv- txoj kev xeb rau wrought hlau railings. Nws koom nrog kev sib koom ua ke ntawm kev sib tsoo hauv cov zinc molten los ua zinc- hlau alloy txheej thiab cov zinc txheej ntshiab ntawm qhov chaw, yog li cais cov hlau los ntawm oxidation. Txoj kev no muaj kev tiv thaiv - xeb lifespan ntau tshaj 20 mus rau 50 xyoo yam tsis tas yuav tsum tau kho; nws muaj kev nyab xeeb, txhim khu kev qha, thiab sawv cev rau qhov zoo tshaj plaws los tiv thaiv- xeb tshuaj rau cov khoom hlau wrought.

Kub-dip Galvanizing txheej txheem ntws
1. Ua ntej- kev tshuaj xyuas thiab kev kho mob: Tshawb xyuas cov khoom ua haujlwm rau cov txheej txheem tsim nyog (rau qhov cua, zinc ntws, thiab kev ncua); soj ntsuam cov qib ntawm xeb thiab txiav txim siab seb puas muaj cov kab mob paug tuaj yeem raug tshem tawm los ntawm hydrochloric acid (cov kab mob xws li xim lossis roj yuav tsum raug tshem tawm ntawm kev kub hnyiab, sib tsoo, lossis alkaline ntxuav).
2. Degreasing (Alkaline ntxuav): Siv cov cuab yeej siv cua sov kom tshem tawm cov roj, cov coatings, thiab lwm yam khoom siv los ntawm qhov chaw ua haujlwm.
3. Kev yaug dej: Tshem tawm alkaline residue thiab lwm yam khoom txuas los ntawm qhov chaw ua haujlwm.
4. Pickling: Tshem tawm xeb, zeb nplai, thiab lwm yam khoom paug.
5. Tshaj tawm -kev tshuaj xyuas thiab kev kho mob: Ntsuas cov txiaj ntsig pickling; rov qab pickling yog tias cov txheej txheem pib tsis txaus, lossis rov- kho thiab rov qab dua yog tias ua ntej- kev npaj pickling tsis txaus.
6. Kev yaug dej: Tshem tawm cov kua qaub thiab lwm yam khoom txuas los ntawm qhov chaw ua haujlwm.
7. Flux daim ntawv thov: Ntxuav lub workpiece nto dua kom nws tsis rov- xeb ua ntej galvanizing.
8. Kev ziab: nce qhov kub ntawm lub workpiece kom tshem tawm cov dej noo ntau dhau, tiv thaiv kev tawg thaum lub sij hawm txheej txheem galvanizing. 9. Kub-dip galvanizing: Lub workpiece yog immersed nyob rau hauv molten zinc ntawm 440℃-470℃rau ib lub sij hawm tshwj xeeb ua ntej muab tshem tawm, uas ua rau cov hlau zinc coworking txheej ntawm ntshiab zinc coworking txheej {{5}.
10. Passivation: Txhim kho lub workpiece nto tiv thaiv atmospheric corrosion thiab ncua qhov pib ntawm xeb dawb.
11. Kev ua kom txias: Tiv thaiv kom txias sai thiab kev cog lus uas tuaj yeem ua rau tawg hauv cov qauv hlau hauv paus.
12. Ua tiav: Tshem cov zinc nodules thiab zinc tshauv adhering rau txheej txheej.
13. Kev tshuaj xyuas: Kev tshuaj xyuas thiab ntsuas cov txheej txheem, nrog rau kev kuaj pom ntawm lub workpiece.
