Kev kho deg Thiab Pickling txheej txheem Technology Ntawm Titanium Rods

Raws li ib qho tseem ceeb ntawm titanium cov ntaub ntawv ua tiav, qhov zoo ntawm qhov chawtitanium barsncaj qha txiav txim siab txog kev pabcuam kev ua haujlwm thiab kev pabcuam lub neej ntawm cov khoom. Nyob rau hauv cov txheej txheem kev kho cua sov ntawm titanium rods, zoo nto kho kom zoo nkauj titanium khoom 'kev ua tau zoo.

I. Vim li cas thiaj yuav tsum tau kho qhov saum npoo?

Titanium rods tsim xoob, tsis zoo sib txuas oxide nplai thaum cua sov (reacting nrog huab cua oxygen, nitrogen, hydrogen), uas cuam tshuam corrosion tsis kam, qaug zog, thiab nto uniformity - ua rau muaj kev pheej hmoo rau aerospace. Cov kab mob hauv av / oxide txheej tuaj yeem ua rau tib neeg tsis lees paub rau kev cog ntoo kho mob. Deg tsis xws luag nyob rau hauv petrochemical pipelines yuav ua rau to. Tsis tas li ntawd, cov txheej txheem kho deg cuam tshuam cov txheej txheem tom ntej xws li txheej thiab vuam.

 

II. Hom Titanium Rod Surface Treatment

 

(I) Kev kho tshuab

Kev kho tshuab yog ib txoj kev kho mob yooj yim uas tshem tawm qhov tsis xws luag, oxide nplai thiab cov kab mob ntawm titanium rods los ntawm kev ua lub cev.

Kev sib tsoo thiab polishing feem ntau yog siv los tshem tawm cov micro- tsis xws luag xws li khawb thiab tawg ntawm cov titanium rods thiab txhim kho qhov chaw tiav.

Sandblasting siv siab - ceev dav hlau abrasive (xws li alumina, quartz xuab zeb) los cuam tshuam rau saum npoo ntawm titanium rods.

Tumbling kev kho mob yog tsim rau kev kho deg ntawm batch titanium rods.

 

(II) Tshuaj Kho Mob

Siv cov tshuaj reagents los teb cov titanium pas nrig qhov chaw rau tu, hloov kho, los yog tiv thaiv zaj duab xis tsim. Cov txheej txheem feem ntau muaj xws li pickling (feem ntau siv), tshuaj polishing, thiab tshuaj hloov dua siab tshiab zaj duab xis kev kho mob, nrog pickling dissolving nto oxides, impurities, thiab roj stains thiaj li yuav restore ib tug huv hlau tsos thiab txhim khu corrosion kuj los ntawm ib tug nyias oxide zaj duab xis.

 

(III) Kev Kho Electrochemical

Siv cov anodic dissolution ntawm titanium rods hauv electrolyte kom tshem tawm deg micro- tsis xws luag thiab kom tau zoo dua nto tiav thiab flatness.

 

(IV) Vapor Deposition Treatment

Tso cov yeeb yaj kiab ua haujlwm zoo rau saum npoo ntawm titanium pas nrig nrog cov pa roj - theem tshuaj tiv thaiv lossis cov txheej txheem ntawm lub cev, suav nrog lub cev vapor deposition (PVD), tshuaj vapor deposition (CVD), thiab lwm yam.

 

III. Titanium qws Pickling txheej txheem Technology

 

(I) Pickling Solution Formula

Lub hauv paus: Titanium pas nrig (ntshiab titanium, titanium alloy), nto oxide nplai thickness, raws li kev kho mob

Cov txheej txheem pickling: Hydrofluoric acid-nitric acid (dav siv), hydrofluoric acid-sulfuric acid

Hydrofluoric acid (HF): Dissolves titanium thiab nws cov oxides; cuam ​​tshuam pickling ceev

HF concentration: 1% -5%

(siab=ntau dhau corrosion/pitting; qis=qis efficiency / unremoved scale)

Nitric acid (HNO₃): Oxidizes inhibit HF corrosion ntau dhau; aids uniform passivation zaj duab xis tsim

HNO ₃ concentration: 10% -20%

Yeem additives: Corrosion inhibitors (txo matrix corrosion), surfactants (txhim kho cov roj emulsification / cleanliness)

 

(II) Tswj cov txheej txheem tseem ceeb

Pickling kub: 20-50℃(tsis txhob siab / qis heev)

Pickling lub sij hawm: 5-30 feeb (kho los ntawm oxide nplai thickness; paub meej los ntawm sampling)

Acid tov kev khiav ceev: xyuas kom zoo ncig (rau tag nrho kev sib cuag thiab kev tshem tawm cov khoom tawm)

 

(III) Pickling Process Flow

Cov txheej txheem ntawm titanium pas nrig pickling muaj xws li: pretreatment → pickling → dej ntxuav → passivation → ziab.

 

 

 

IV. Yav tom ntej Optimization

Composite kev kho mob: Muab ntau yam thev naus laus zis ("sandblasting + pickling + anodizing", "electropolishing + plasma spraying") kom ua tiav cov txiaj ntsig zoo, xws li kev txhim kho corrosion thiab pob txha muaj peev xwm, haum rau cov khoom siv kho mob.

Cov txheej txheem ntsuab : Ua kom zoo rau cov tsoos pickling tsis xws luag nrog qis -toxicity/low-emission technologies, piv txwv li citric acid-hydrofluoric acid system, acid-dawb txoj kev xws li laser (tsis muaj kuab paug, siab precision) thiab ultrasonic tu.

Cov txheej txheem ntse: Xaiv kev saib xyuas online (tseem- lub sijhawm tshawb pom cov kua qaub, thiab lwm yam) thiab PLC / neeg hlau thev naus laus zis kom paub meej qhov kev hloov pauv, tsis siv neeg ua haujlwm, thiab txhim kho kev kho mob sib xws.
