Q: Lub cev lub cev ua haujlwm dab tsi ntawm zinc txheej ua si?
A: Coolate Corrosive Media
Lub zinc txheej (feem ntau ntshiab zinc lossis zinc alloy) yog nruj, acid thiab alkali uas txwv tsis pub muaj rowing ntawm substrate .
Cawv ntawm txheej tuab tuab
Corrosion kev tawm tsam yog ncaj qha cuam tshuam nrog lub thickness ntawm zinc txheej {}} qhov ntau dua cov txheej txheem tuab, ntev dua cov txheej txheem kav ntev.
Q: Lub luag haujlwm yog lub chaw tiv thaiv hluav taws xob ntawm zinc txheej ua si?
A: Thaum lub zinc txheej puas yog vim cov khawb, hnav thiab kua muag txheej, cov txheej txheej zinc thiab txheej zinc thiab cov roj teeb.
Zinc, raws li anode, yog corroded ua ntej, yog li tiv thaiv cov hlau substrate li cathode {0} .
Txawm hais tias lub zinc txheej yog ib nrab puas tsuaj, kev xeb ntawm cov txheej txheem hluav taws xob tseem tuaj yeem ncua rau lwm cov tshuaj pleev pob zeb (xws li npib tsib xee) .
Q: Yuav ua li cas lub corrosion resistance ntawm galvanized coils ua nyob rau hauv cov cheeb tsam sib txawv?
A: {1. nyob deb nroog / chaw qias neeg dawb
Tus nqi corrosion yog tsawg kawg thiab zinc txheej yuav ruaj khov rau lub sijhawm ntev {}
2. Nroog / Chaw Kho Mob
Tus nqi ua xeb yog nce los ntawm cov kuab paug thiab cov txheej txheem nitrogen tuaj yeem tseem ua kom zoo dua corrosion los ntawm kev sib sau ua yeeb yam corrosion) .
3. chaw nres nkoj
Cov tshuaj tsuag ntsev ntau lub zog ua kom nrawm nrawm nrawm ntawm cov kab ke
Q: Cov tshuaj lom neeg tsis kam ntawm galvanized coils xav tau?
A: {1. kua qaub thiab alkali tsis kam
Lub zinc txheej yog yooj yim corroded nyob rau hauv dilute acids (xws li sodium hydroc acci acid thiab citric acid thiab citric acid nyob rau hauv kev ua zaub mov noj).
{{0 {}} tsis kam rau cov kuab tshuaj muaj kuab
Cov txheej zinc yog qhov tsis txaus siab rau cov kuab tshuaj yeeb yaj kiab xws li roj, thiab yog tsim nyog rau cov duab kos duab thiab luam ntawv (xws li cov tshuab hluav taws xob) tsev) {}}}
Q: Yuav ua li cas ntxiv txhim kho lub corrosion tsis kam ntawm Galvanized coils los ntawm cov txheej txheem kev kho mob?
A: {1. chromate passivation
Hauv cov txheej txheem ib txwm muaj, cov yeeb yaj kiab passivation yog tsim nyob rau ntawm lub zinc Txheej Kuj (xws li nce cov tshuaj lom neeg lub cav, nws yog maj mam tshem tawm .
{{02. chromium-pub dawb passiveation (cov txheej txheem hloov tshiab)
Siv cov txheej txheem zoo ib puag ncig xws li kev ua si, titanate, thiab kev tiv thaiv kev tiv thaiv, thiab ua raws li kev tiv thaiv ib puag ncig, thiab ua raws li ROHS .
3. roj lossis ntiv tes ua haujlwm kho
Cov roj roj ntau heev lossis cov txheej txheem organic los tiv thaiv cov txheej txheem zinc thaum muaj kev sib tsoo nrog cov khoom siv hauv tsev xws li cov khoom vaj rooj tog thiab rooj tog {}
