Sharaxaada
calaamadeeye
Hordhac Product
Daaweynta dusha sare: Habka passivation zinc midabka (c2C) waa la qaatay, dhumucdiisuna waxay tahay 8-15μm, caabbinta daxalka ee tijaabada buufinta milixdu waa in ka badan saacadaha 72, kaas oo leh labadaba ka hortagga daxalka iyo qurxinta.
Waxqabadka: Marka la barbar dhigo boolal koronto oo koronto ah oo zinc-plated ah, alaabada midabka zinc-plated waxay leeyihiin iska caabin adag oo daxalka ah ee qoyaanka, wasakhowga warshadaha iyo jawiga kale, iyo muuqaal qurux badan, oo ku habboon bannaanka ama mashaariicda leh shuruudaha muuqaalka sare.
Codsiga: Caadi ahaan loo isticmaalo bay'adaha qallafsan sida buundooyinka, tunnel-yada, iyo injineernimada badda, iyo sidoo kale hagaajinta bannaanka ee qurxinta dhismaha, sida daaqadaha iyo daboolka.
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.
