Usha biinanka ku dhejisan zinc madow
Iyada oo loo marayo daaweynta dareeraha passivation madow (c2D) oo ka kooban milix qalin ah ama cusbo naxaas ah, filim passivation madow ayaa la sameeyay oo dhumucdiisu tahay 10-15μm. Kharashku waa sarreeyaa laakiin muuqaalku waa mid gaar ah.
Sharaxaada
calaamadeeye
Hordhac Product
Habka: Iyada oo loo marayo daaweynta dareeraha passivation madow (c2D) oo ka kooban milix qalin ah ama cusbo naxaas ah, filim passivation madow ayaa la sameeyay oo dhumucdiisu tahay 10-15μm. Kharashku waa sarreeyaa laakiin muuqaalku waa mid gaar ah.
Waxqabadka: Iska caabbinta daxalka ayaa ka fiican zinc midabka leh, gaar ahaan heerkulka sare ama deegaanka huurka sare. Way deggan tahay oo waxay leedahay iska caabin xidhid gaar ah. Waxay ku habboon tahay muuqaallada gaarka ah sida qurxinta iyo nuugista kulaylka qorraxda.
Codsiga: Isku xirka saxda ah ee qaybaha baabuurta (sida biinanka masaxaha), qalabka farsamada ee dhamaadka-sare, iyo munaasabadaha meesha dabar goynta ama faragelinta elektromagnetic-ka loo baahan yahay.
Isbarbardhigga daaweynta dusha sare iyo talooyinka xulashada
| Habka daaweynta | Midabka | Kala duwanaanta dhumucda | Tijaabada buufinta milixda | Iska caabbinta daxalka | Xiro iska caabin | Xaaladaha codsiga muhiimka ah |
| Electrogalvanization | Cadan qalin ah / buluug-cad | 5-12μm | 24-48 saacadood | Guud ahaan | Dhexdhexaad | Deegaanka qallalan ee gudaha, isku xirka farsamada caadiga ah |
| Dajinta zinc midabka leh | Midabka qaanso-roobaadka | 8-15μm | In ka badan 72 saacadood | Wacan | Dhexdhexaad | Banaanka, qoyaanka ama jawi khafiif ah oo daxalka leh |
| Dajinta zinc madow | Madow | 10-15μm | In ka badan 96 saacadood | Aad u fiican | Wacan | Heerkulka sare, huurka sare ama muuqaalada qurxinta |
Soo jeedinta xulashada:
Arrimaha deegaanka: Darista zinc-midabka leh ama dajinta zinc-ka madow ayaa la door bidaa meelaha qoyan ama warshadaha; Electrogalvanizing waxaa lagu dooran karaa deegaanka gudaha ee qalalan.
Shuruudaha culeyska: Xaaladaha culeyska sarreeya, waxaa lagama maarmaan ah in la doorto boodhadhka fidinta ee darajooyinka ku habboon (sida 8.8 ama ka sarreeya) marka loo eego miiska qeexitaanka, oo fiiro gaar ah u yeelo saameynta habka galvanizing ee guryaha farsamada (sida galvanizing kulul-kuleelka ayaa laga yaabaa inay keento hoos u dhac ku yimaada xoogga xajinta ee ku saabsan 5-10%).
Shuruudaha deegaanka: Darista zinc-midabka leh iyo darista zinc-ga madow waxa ku jiri kara chromium hexavalent waana in ay u hoggaansamaan awaamiirta deegaanka sida RoHS; galvanizing qabow (electrogalvanizing) waxay leedahay waxqabad deegaan oo ka fiican oo kuma jiraan biro culus.
Shuruudaha muuqaalka: Ku dhejinta zinc-ka midabka leh ama dhejiska zinc-ka madow ayaa doorbidaya muuqaallada qurxinta, iyo electrogalvanizing ayaa loo dooran karaa isticmaalka guud ee warshadaha.
