Q: Yuav ua li cas xaiv cov txheej txheej hauv cov chaw sib txawv?
A: Cov txheej txheem corrosive (c 5- m): zinc-coating yog 5 ~ 10 zaug uas ntshiab zinc {{}
Nruab Nrab Corrosive (C 3- C4): Hot-Dip Galvanizing (25 ~ Promer-Free Pass 15 ~ 30 Xyoos .
Q: Yuav ua li cas txuas tau kev pabcuam lub neej ntawm Galvanized steel?
A: Kev Kho Vaj Tse
Passivation txheej txheem: chromium-pub dawb passivation nce kev pabcuam lub neej los ntawm 10% ~ 30%, uas yuav tsum tau them rau txheej tuab tuab.
Txheej superposition: Thov fluorocarbon toffcoat ntawm zinc-aluminium txheej muaj peev xwm txuas ntxiv rau ntau tshaj 25} m ib puag ncig .
Ua thiab Txij Nkawm
Kev puas tsuaj tsim: kev txiav ntug yog kho nrog zinc-nplua nuj xim (zinc cov ntsiab lus ntau dua lossis sib npaug ntawm 90%), uas tuaj yeem kho tau ntau dua 90% ntawm kev tiv thaiv kev ua haujlwm {}}
Kev soj ntsuam tsis tu ncua: Siv txheej txheej txheej txheej tuab ntawm cov txheej txheem tuab ntawm cov xim tuab ntawm txheej, thiab rov ua rau nws hauv qab no.
Q: Puas yog lub thickness ntawm galvanized txheej fab cuam tshuam cuam tshuam rau lub neej pabcuam?
A: Lub thickness ntawm cov txheej galvanized yog ib qho ntawm cov kev pab cuam corrosive (xws li txheej txheem kev ua haujlwm ntawm lub neej (oxyen, ntsev, acid}) los ntawm kev hu ncaj qha rau tus hlau Substrate. Qhov ntau dua nws yuav siv cov xov xwm corrosive kom nkag mus rau cov txheej txheem, thiab lub neej ntev dua {}}
Q: Cov txheej txheem tom qab kev kho mob tuaj yeem txhim kho cov txheej txheem corrosion tsis kam ntawm zinc txheej tsis nce nws cov tuab?
A: {{1. Kev Kho Mob Passus yog tsim los ntawm Chromate (lossis Chromium-Dawb Passivation tus neeg sawv cev) txhawm rau inhibit Electrochemical corrosion {2}
2. Sealing kev kho mob: ib qho txheej txheem organic (xws li resin) lossis cov kab xev yog siv rau cov txheej thiab txhim kho kev sib cais .
3.} }lal diffusion kev kho mob: xws li cov txheej txheem sib txawv los txhim kho lub peev xwm los tiv thaiv kev kub thiab tshuaj lom neeg.
4.} txheej polyoy, zinc-epyic pleev xim rau, eploic txheej thiab lwm yam kev sib cais ntawm kev tawm tswv yim ntawm corrosive {}}
{{06. nano txheej thev naus laus zis: txau nanes thiab silicon dioxide los ua ib qho ultra-nyias muaj siab tiv thaiv .
Q: Qhov kev cuam tshuam dab tsi ntawm galvanizing kev ntsuas thickness muaj rau cov nqi?
A: Lub thickness ntawm galvanized steel yog nonlinearly zoo correlated nrog kev txhim kho cov khoom siv hluav taws xob (alloy} {} txheej kom txo cov nqi .
