1. Dab tsi yog kub dipped galvanization?
Kub dipped galvanization yog txheej txheem uas cov hlau dipped rau hauv lub pas dej ua ke ntawm zinc. Txhawm rau ua cov hlau galvanized siv txoj kev no, peb yuav tsum ua raws li 4 kauj ruam: ntxuav qhov chaw, fluxing, kub-dipping & txias.
2. Pre-galvanizing yog dab tsi?
Pre-galvanizing tseem hu ua zeb galvanizing. Cov txheej txheem no yog ze heev rau kub dipped galvanization tab sis ua nyob rau hauv thawj theem ntawm ntau lawm. Nws ib txwm tshwm sim ntawm cov hlau zeb ntawm cov ntaub ntawv uas twb muaj cov duab tshwj xeeb lossis ua ntej txiav rau hauv qhov ntau thiab tsawg thiab ua tiav.
Pre-galvanizing muaj qee cov kauj ruam ntawm kub dipped galvanization xws li ntxuav qhov chaw, dipping rau hauv cov dej kub zinc dej ua ke nrog cov txheej txheem rov qab.
Cov txheej txheem kub-dip galvanizing tiv thaiv cov hlau hauv peb txoj hauv kev tseem ceeb, tab sis tej zaum txoj kev tseem ceeb tshaj plaws yog los ntawm kev ua cov txheej txheej rau cov hlau. Cov zinc nyob rau hauv cov txheej tiv thaiv ua si ua anode rau cov hlau. Tom qab muaj kev kub-dip galvanization, lub peev xwm tiv thaiv tau txhim kho raws li zinc tam sim no dhau los ua ib feem ntawm cov hlau.
Lub caij no, raws li cov khoom ua ntej galvanized muaj cov txheej nyias nyias thiab yuav raug txiav tom qab rau qhov ntau thiab tsawg, kev tiv thaiv kev txi yuav zoo li kub-dip galvanized steel.
| Feature | Kub dipped galvanization | Pre-galvanizing |
|---|---|---|
| Txheej thickness | Cov txheej tuab nrog qhov nruab nrab yam tsawg kawg nkaus ntawm 45-85μm hauv BS EN ISO 1461 | Cov txheej tuab yuav txawv tab sis feem ntau yog circa 20μm rau cov ntawv thiab 20-30μm rau cov hlab thiab cov xov hlau |
| Txheej tsis tu ncua | Nruam txheej ntawm tag nrho cov khoom | Uncoated cheeb tsam ntawm txiav ntug |
| Txheej daim ntawv cog lus | Muaj zog metallurgical daim ntawv cog lus nrog lub hauv paus hlau | Muaj zog metallurgical daim ntawv cog lus nrog lub hauv paus hlau |
| Txheej formability | Kev tsim tom qab kub dipped galvanizing yog tsis qhia raws li nws yuav ua rau lub txheej puas | Cov txheej nyias nyias tuaj yeem tsim ib txwm tsis muaj kev puas tsuaj |
| Txheej txheej | Feem ntau ci tab sis tuaj yeem hloov pauv | Nquag archieve ib lub teeb ci |
| Abrasion tsis kam | Thicker txheej ntawm hard zinc-hlau alloy muab lub siab ua haujlwm rau kev puas tsuaj | Nyias txheej txheej nrog txo tsis kam mus rau abrasion |
| Kev tiv thaiv kev txi | Muab qhov siab tshaj plaws ntawm kev tiv thaiv kev txi | Txo kev tiv thaiv kev txi vim nyias txheej txheej thiab ntawm qee qhov chaw tsis muaj coated (txiav npoo) |
Cov lus kawg
Muaj ntau qhov sib txawv ntawm kub-dipped galvanization thiab pre-galvanizing txheej txheem. Paub txog qhov sib txawv no yuav ua rau peb xaiv txoj kev tsim nyog tshaj plaws & cov khoom lag luam rau koj cov haujlwm. Ntawm tag nrho, nws yog ib txwm tsim nyog los xaiv qhov zoo tshaj plaws galvanized steel khoom ntawm ntau yam kev xaiv ntawm lub khw.
