Kev siv ntawm Anodizing hauv Rail Transit

Anodizing yog cov cuab yeej kho saum npoo uas tsim cov oxide zaj duab xis ntawm cov hlau nto los ntawm cov txheej txheem electrochemical, thiab nws tau siv dav hauv kev tsheb ciav hlau. Cov thev naus laus zis no tuaj yeem txhim kho qhov kev tiv thaiv corrosion, hnav tsis kam, rwb thaiv tsev, thiab zoo nkauj ntawm cov ntaub ntawv hlau, muab kev lees paub tseem ceeb rau kev ua haujlwm ntev - lub sijhawm txhim khu kev qha ntawm cov khoom siv tsheb thauj mus los. Tsab ntawv xov xwm no yuav tham txog cov ncauj lus kom ntxaws txog cov ntawv thov tshwj xeeb ntawm anodizing hauv kev thauj mus los thiab nws cov txiaj ntsig zoo.

I. Txheej txheem cej luam ntawm Anodizing Technology

Anodizing yog txheej txheem kev kho mob electrochemical, feem ntau siv rau txhuas thiab nws cov alloys. Nws lub hauv paus ntsiab lus yog muab cov txhuas qhov chaw ua lub anode nyob rau hauv ib qho electrolyte, thiab siv ncaj qha tam sim no los ua ib qho oxidation cov tshuaj tiv thaiv ntawm aluminium nto, ua ib tug tuab aluminium oxide zaj duab xis. Cov oxide zaj duab xis no muaj cov yam ntxwv hauv qab no:

1. High hardness: oxide zaj duab xis hardness tuaj yeem ncav cuag HV300-500, txhim kho qhov hnav tsis kam.

2. Corrosion kuj: Alumina muaj cov tshuaj ruaj khov thiab tuaj yeem tiv taus qhov yaig ntawm qhov chaw, noo noo, thiab tshuaj lom neeg tawm.

3. Rwb thaiv tsev cov khoom: Cov oxide zaj duab xis muaj cov khoom siv rwb thaiv tsev zoo heev thiab cov nplaim hluav taws kub.

4. Cov qauv ntxeem tau: Cov yeeb yaj kiab uas tsis muaj oxide muaj cov qauv microporous, yooj yim rau cov xim tom qab los yog sealing kev kho mob.

Nyob ntawm seb hom electrolyte thiab cov txheej txheem tsis, anodizing tuaj yeem muab faib ua ntau hom, xws li sulfuric acid anodizing, oxalic acid anodizing, thiab chromic acid anodizing. Ntawm lawv, sulfuric acid anodizing yog dav siv nyob rau hauv rail tsheb thauj mus los teb.

II. Daim ntawv thov tseem ceeb ntawm Anodizing hauv Rail Transit

1. Lub Cev Lub Cev Cov Khoom Siv Khoom Siv

Rail tsheb thauj mus los feem ntau siv cov ntaub ntawv aluminium alloy hauv lawv lub cev. Anodizing tseem ceeb txuas ntxiv lub neej kev pab cuam ntawm cov khoom no:

- Lub Cev Lub Cev Lub Cev: Tawm los ntawm cua, nag, thiab atmospheric corrosion, anodizing tuaj yeem txuas lub tsheb lub cev lub neej los ntawm ntau tshaj 10 xyoo.

- Roof Structure: Raug rau qhov chaw hnyav, oxide zaj duab xis tiv thaiv corrosion thiab UV aging.

- Qhov Rooj Ncej: Feem ntau qhib thiab kaw qhov chaw sib txhuam; oxide zaj duab xis txhim kho hnav tsis kam.

2. Cov khoom siv sab hauv

Rail transit tsheb sab hauv trim Cheebtsam yuav tsum tsis tsuas yog durability tab sis kuj zoo nkauj:

- Tes tuav thiab railings: nquag kov thaj chaw los ntawm cov neeg caij tsheb; anodizing txhim kho hnav tsis kam thiab ntiv tes tiv thaiv.

- Rooj Ncej: Cov kabmob dynamic loads; oxide zaj duab xis txhim kho kev qaug zog.

- Lub Hnab Racks: Yuav tsum muaj kev sib txhuam hnyav; anodizing nce hardness.

3. Cov Khoom Siv Hluav Taws Xob

Rail transit hluav taws xob systems muaj cov cai nruj heev rau rwb thaiv tsev thiab corrosion kuj:

- Conductor Rail Insulation Brackets: Anodizing muab cov rwb thaiv tsev zoo heev.

- Hluav taws xob enclosure: Tiv thaiv luv luv Circuit Court thiab corrosion tshwm sim los ntawm huab cua puag ncig

- Cov teeb liab system Cheebtsam: Ua kom muaj kev ruaj ntseg thiab kev ntseeg tau ntawm cov teeb liab kis

4. Bogie system

Lub bogie yog ib qho tseem ceeb ntawm cov tsheb ciav hlau thauj mus los, ua haujlwm nyob rau hauv ib puag ncig hnyav:

- Bogie Cheebtsam: Tiv thaiv kev co thiab cuam tshuam; oxide zaj duab xis txhim kho kev tiv thaiv kev ntxhov siab corrosion

- Braking system Cheebtsam: Nyob rau hauv qhov kub thiab txias ib puag ncig, oxide zaj duab xis tswj kev ruaj ntseg

III. Technical zoo ntawm anodizing nyob rau hauv rail transit

1. Ntsuas qhov hnyav thiab lub zog

Rail Transit tseem ceeb tshaj qhov tsim qauv tsim kom txo tau lub zog siv. Anodizing aluminium alloys tuaj yeem txo qhov hnyav thaum tuav lub zog txaus thiab kav ntev. Cov oxide zaj duab xis bonds khov kho rau lub substrate, tiv thaiv txheej tev tawm.

2. Kev ua tau zoo ib puag ncig

Piv rau cov txheej txheem electroplating ib txwm, anodizing yog ib puag ncig zoo dua:

- Tsis siv cov tshuaj phem xws li chromium.

- Kev kho dej khib nyiab yooj yim, ua rau muaj kuab paug tsawg.
