Ntshiab titanium phaj sov pickling txheej txheem

Cov txheej txheem sov so ntawm cov ntshiab titanium daim hlau thiab strips suav nrog cov txheej txheem ua ntej ntxuav, uas yog tus cwj pwm hauv qhov ntawd: cov txheej txheem sov so ntawm cov ntshiab titanium daim hlau thiab strips kuj suav nrog cov txheej txheem hauv qab no tom qab kev ntxuav ua ntej:
Kev ntxuav dej thiab txheej txheem pickling. Cov txheej txheem ntxuav dej siv dej nrog dej kub hauv thaj tsam ntawm 35 txog 45 degree; Cov muaj pes tsawg leeg thiab cov ntsiab lus ntawm cov tshuaj siv nyob rau hauv cov txheej txheem pickling yog: HNO3: 190 ~ 280g / l; HF: 15 ~ 45g / l; hlau ions nyob rau hauv cov kua qaub Cov ntsiab lus: 10 ~ 35g / l; Pickling lub sij hawm: 1.5 ~ 1.75min, acid kub: 35 degree ~ 45 degree. Qhov no ntshiab titanium phaj sov pickling txheej txheem yuav txo tau tus naj npawb ntawm kev sib txuas ntawm muaj zog acid daws, zoo txo ​​cov re-acidification tus nqi, xyuas kom meej passivation tiv thaiv nto ntawm ntshiab titanium daim hlau, daws qhov teeb meem ntawm macular tsis xws luag nyob rau saum npoo ntawm ntshiab titanium daim hlau. , thiab txhim kho ntau lawm efficiency yam tsis tas yuav tsum tau tshwj xeeb Passivation kev kho mob txo cov nqi ntau lawm.

Ntshiab titanium phaj yog cov khoom siv hlau nrog zoo heev corrosion kuj thiab siab zog. Nws feem ntau yog siv dav hauv kev lag luam chemical, marine engineering, aerospace thiab lwm yam kev lag luam. Sov pickling yog ib qho txheej txheem kev kho mob uas feem ntau siv los tshem tawm cov oxides, cov kab mob thiab lwm yam khoom tsis zoo rau saum npoo ntawm titanium ntshiab thiab txhim kho nws qhov zoo thiab corrosion kuj. Cov hauv qab no yog cov lus qhia luv luv rau cov txheej txheem sov so ntawm cov titanium ntshiab:
Kev Npaj: Xyuas kom cov neeg ua haujlwm hnav cov khoom tiv thaiv tus kheej tsim nyog, xws li tsom iav tiv thaiv, hnab looj tes, khaub ncaws tiv thaiv, thiab lwm yam.
Npaj cov tshuaj uas yuav tsum tau ua. Cov kua qaub feem ntau yog siv rau hauv qhov sov so xws li sulfuric acid, hydrofluoric acid, thiab lwm yam.
Ntxuav qhov chaw: Ua ntej sov so, ntxuav lub ntsej muag ntawm cov titanium ntshiab kom tshem tawm cov plua plav, roj thiab lwm yam impurities ntawm qhov chaw.
Cov tshuaj ntxuav alkaline lossis lwm txoj kev ntxuav kom zoo tuaj yeem siv los xyuas kom meej qhov chaw huv.
Immersion sov pickling: Muab cov ntshiab titanium phaj rau hauv cov kua qaub, feem ntau yog sib xyaw ntawm sulfuric acid thiab hydrofluoric acid. Tswj qhov kub thiab txias. Feem ntau, qhov kub ntawm qhov sov sov yog nyob nruab nrab ntawm 50 degree thiab 80 degree. Qhov tshwj xeeb kub nyob ntawm cov txheej txheem yuav tsum tau ua.
Lub sij hawm kuj tseem ceeb heev, nrog rau lub sij hawm ntxuav feem ntau yog li ntawm kaum feeb mus rau teev kom paub meej tias kev tshem tawm cov oxides saum npoo av thiab cov khoom paug.
Neutralization thiab rinsing: Tom qab qhov sov so ua tiav, cov kua qaub yog neutralized. Cov tshuaj alkaline tuaj yeem siv los ua kom tsis muaj kua qaub.
Yaug cov ntshiab titanium phaj los xyuas kom meej tias tag nrho cov kua qaub yog ntxuav kom tsis txhob acid residue los ua corrosion.
Kev ziab kom qhuav: Cov phaj titanium uas ntxuav huv huv tuaj yeem qhuav los ntawm huab cua kom qhuav lossis lwm yam kev tsim nyog los xyuas kom meej qhov chaw qhuav thiab tiv thaiv kev ua qias tuaj.
Sov pickling yog ib qho kev kho mob saum npoo av rau cov ntshiab titanium, tab sis nws yuav tsum tau muab sau tseg tias cov txheej txheem kev nyab xeeb yuav tsum tau ua raws li nruj me ntsis thaum lub sijhawm ua haujlwm kom tsis txhob muaj kev puas tsuaj rau tib neeg lub cev thiab ib puag ncig. Tsis tas li ntawd, cov txheej txheem tshwj xeeb thiab kev xaiv tshuaj yuav tsum tau hloov kho raws li qhov xwm txheej tiag tiag thiab cov kev xav tau.
