Taw qhia rau cov txheej txheem pickling ntawm titanium daim hlau

Titanium phaj pickling yog txheej txheem kev kho saum npoo uas siv los tshem tawm oxides, roj, plua plav thiab lwm yam impurities rau ntawm daim hlau titanium los txhim kho nws qhov zoo thiab weldability. Cov hauv qab no yog cov txheej txheem titanium phaj pickling:

1. Tshem tawm cov roj stains thiab impurities: Ua ntej, tsau cov titanium phaj hauv cov tshuaj alkaline kom tshem tawm cov roj stains thiab lwm cov organic impurities ntawm qhov chaw.

2. Tshem tawm cov oxide txheej: Titanium daim hlau yooj yim tsim ib txheej oxide nyob rau hauv cov huab cua, uas yuav cuam tshuam rau cov vuam thiab kev sib txuas ua haujlwm. Ua ntej tshem tawm cov oxide txheej, titanium phaj yuav tsum tau tsau rau hauv cov kua qaub uas muaj zog, xws li nitric acid lossis hydrofluoric acid, kom tshem tawm cov oxide txheej ntawm qhov chaw.

3. Pickling: Soak lub titanium phaj nrog oxide txheej tshem tawm hauv cov kua qaub, xws li nitric acid los yog sulfuric acid, kom tshem tawm lwm yam impurities thiab oxides kom cov nto mus txog qhov yuav tsum tau ua kom huv si.

4. Neutralization kev kho mob: Tom qab pickling, titanium phaj yuav tsum tau tsau rau hauv ib qho alkaline tov rau neutralization kev kho mob rau neutralize cov acidic tshuaj uas tseem tshuav nyob rau hauv lub pickling txheej txheem thiab xyuas kom meej tias tsis muaj acidic tshuaj nyob rau saum npoo.

5. Kev ntxuav dej: Thaum kawg, lub phaj titanium tau ntxuav tag nrho nrog dej kom ntseeg tau tias tag nrho cov kua qaub thiab alkaline daws tau raug ntxuav kom tsis txhob muaj qhov tsis zoo rau cov txheej txheem thiab kev siv tom ntej.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov txheej txheem pickling suav nrog kev siv cov kua qaub uas muaj zog, thiab cov tshuaj no tuaj yeem tsim kev puas tsuaj rau ib puag ncig thiab cov neeg ua haujlwm. Yog li ntawd, thaum pickling titanium daim hlau, nws yog ib qho tsim nyog yuav tsum nruj me ntsis ua raws li cov txheej txheem kev nyab xeeb, siv cov cuab yeej tiv thaiv tus kheej tsim nyog, thiab pov tseg cov kua khib nyiab kom zoo kom muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig. Tsis tas li ntawd, cov txheej txheem tshwj xeeb thiab kev siv tshuaj yuav txawv ntawm cov tuam ntxhab lossis cov ntawv thov. Yog li ntawd, nws raug pom zoo tias thaum pickling titanium daim hlau, nws yuav tsum tau ua raws li cov kev qhia tshwj xeeb thiab kev khiav hauj lwm cov txheej txheem muab los ntawm cov tuam ntxhab.
