Anodizing puas ua tiav siab - precision ua?

Ib qho kev sib tham txog kev ua tiav ntawm kev ua tiav siab - precision anodizing cov txheej txheem

Anodizing yog ib qho txheej txheem kev kho kom zoo nkauj, dav siv rau kev hloov kho deb ntawm txhuas thiab nws cov alloys. Nrog rau kev nce nqi ntxiv hauv kev lag luam kev lag luam, ua tiav siab {1} Precision tswj nyob rau hauv anodizing cov txheej txheem tau dhau los ua qhov tseem ceeb hauv kev lag luam. This article systematically explores the technical approaches to achieving high-precision anodizing processes from multiple perspectives, including process parameter control, equipment optimization, pre-treatment processes, and post-treatment technologies.

I. Kev tswj hwm cov txheej txheem tsis

Thawj qhov yuav tsum tau ua tiav rau kev ua tiav siab - precision anodizing cov txheej txheem yog tsim kom muaj cov txheej txheem uas tsis raug ntsuas hluav taws xob. Electrolyte kub, tam sim no ceev, voltage, thiab lub sij hawm yog plaub yam tseem ceeb uas cuam tshuam qhov tseeb thiab sab qhov tseeb ntawm cov yeeb yaj kiab oxide.

Qhov kub thiab txias yuav tsum tau tswj hwm rau qhov tseeb ntawm ± 0.5 degree. Cov kev hloov pauv hloov pauv tuaj yeem ua rau cov neeg sib tw ntawm cov yeeb yaj kiab uas tsis sib xws. Ntau - theem cua txias txias thiab muab faib tawm cov sensors kub tuaj yeem txhim kho qhov kub kev tswj qhov kub. Tam sim no ceev tswj yuam kev yuav tsum tsawg dua 3%. Ib qho kev siv hluav taws xob tas li nrog qhov tseeb - lub sij hawm tswv yim tawm tswv yim kom ruaj khov. Qhov voltage fundogressive ntau yuav tsum tau tswj hwm hauv ± 1V. Tshwj xeeb tshaj yog thaum lub hard anodizing, kev hloov me me hauv voltage tuaj yeem cuam tshuam ntau rau cov yeeb yaj kiab hardness. Lub sijhawm ua haujlwm yuav tsum tau tswj hwm nrog qhov ntsuas qhov tseeb mus rau theem thib ob. Ib lub sijhawm siv sijhawm ua haujlwm, ua ke nrog kev txhim kho cov txheej txheem kev paub, kom pom tseeb lub sijhawm tswj.

Ii. Cov Khoom Siv Tshwj Xeeb thiab Kev Tuam Txhab Tsim

Siab - precision anodizing cov txheej txheem muab cov khoom tshwj xeeb xav tau ntawm cov cuab yeej. Lub cell electrolytic yuav tsum tau tsim ntawm corrosion- Cov ntaub ntawv tiv thaiv nrog 0.8μm los txo cov kev ntxhov siab hauv electrolyte. Qhov kev sib txawv ntawm qhov kev ncua deb ntawm cov Cathode thiab anode yuav tsum tsawg dua 1 hli, thiab cov khoom siv hluav taws xob yooj yim yuav tsum tau siv los xyuas kom meej. Lub zog hluav taws xob yuav tsum muaj DC tso tawm nrog lub peev xwm ripple ntawm tsawg dua 1% thiab yuav nruab nrog ntau- theem kev tswj hwm.

Kev tsim qauv qauv yuav tsum muaj kev txiav txim siab ntawm clamping txoj hauj lwm raug thiab ua kev cai coj ua. Tshwj xeeb fixtures yuav tsum xyuas kom meej tias cov txheeb ze cov kev ua haujlwm tsis sib haum xeeb ntawm kev sib cuag sib cuag sib txawv ntawm tsis muaj ntau tshaj 5%. Rau cov workpieces nyuaj, lub cev hluav taws xob sib txuas tau tsim los ua kom tiav cov hluav taws xob hluav taws xob ntau dua.

III. Pretricate txheej txheem optimization

Qhov zoo tshaj ntawm pretreatment ncaj qha cuam tshuam rau qhov precision ntawm anodizing. Txoj kev txheej txheem degreast yuav tsum tshem tawm ntawm cov roj sib txawv, nrog cov roj uas seem ntawm cov yeeb yaj kiab tuab tuab ntawm tsawg dua 10nm. Thaum Alkaline etching, tus nqi corrosion yuav tsum ua tib zoo tswj hwm. Corrosion Inhibitors tuaj yeem siv los ua kom qhov kev hloov pauv tsis pub dhau 5%. Polishing yuav tsum tau ua cov tshuab siv tshuab polishing lossis electrolytic polishing, nyob ntawm qhov kev xav tau kawg. Lub saum npoo av roughness ra yuav tsum tau tswj tsis pub dhau ntawm 0.2-0.4μm.

Rau cov haujlwm ua haujlwm xav kom muaj kev cuam tshuam ntau, tshuaj lom neeg theem tuaj yeem raug ntxiv, siv cov kua txob ntawm 90} 14 degree, thiab lub sijhawm kho kom raug rau tus thib ob. Post -}}}}}}} Cov txheej txheem dej tiv thaiv tsawg kawg 1Mivk los tiv thaiv kom tsis txhob muaj cov tshuaj tsis huv.

IV. Precision tswj cov electrolyte system

Qhov kev ruaj ntseg ntawm electrolyte muaj pes tsawg leeg yog qhov tseem ceeb rau high - precision machining. Cov sulfuric acid concentration nyob rau hauv sulfuric acid anodizing kev daws yuav tsum tau tswj hwm ntawm 180-200g / u, thiab txhuas ion cov ntsiab lus yuav tsum tsis tshaj 15g / l. Cov ntsuas kub online thiab cov hluav taws xob tsis siv neeg yuav tsum tau siv los tswj cov kev pab cuam sib luag. Rau cov anodizing nyuaj, xws li cov organic acids (xws li oxalic acid thiab malic acid) tuaj yeem ntxiv rau hauv electrolyte los txhim kho zaj duab xis kev ua yeeb yaj kiab. Qhov nyiaj ntxiv yuav tsum tau tswj tsis pub dhau 5-15G / u nrog qhov tseeb ntawm ± 0.5g / l.

Yuav tsum muaj cov txheej txheem hluav taws xob hauv electrolyte nrog ib tug 1μm precision lim, thiab cov teeb meem teeb meem yuav tsum tau tswj hwm kom tsawg dua lossis sib npaug rau 5mg / l. Tus nqi ntws tsawg yuav tsum tau tsim los raws li lub tank loj kom ntseeg tau tias tus nqi ntws ntws thoob plaws lub tank, nrog kev sib txawv ntawm tsis muaj ntau tshaj 10%. Cov thev naus laus zis tshuab hluav taws xob tuaj yeem txuas ntxiv txhim kho zaj yeeb yaj kiab ua yeeb yam. Mem tes zaus yuav tsum tau tswj tsis pub dhau 50-100Hz, nrog kev kho lub luag haujlwm hloov kho ntawm 30-70%.

V. Post - kev kho mob thiab kev siv tshuab

Tshaj tawm -} Kev kho cov kauj ruam yog qhov tseem ceeb rau kev tswj hwm qhov ruaj khov ntawm cov yeeb yaj kiab oxide. Txog kev sib khi txias, cov dej kub yuav tsum tau tswj ntawm 25 ± 1℃rau 20- 30 feeb; Rau kev sib khi thaum tshav kub Rau cov yeeb yaj kiab nyuaj anodized uas tsis tas yuav tsum tau se, ib txoj kev siv hluav taws xob tsawg tsawg tuaj yeem siv ntawm 60-80℃rau 30-60 feeb.

Thaum lub sij hawm dyeing cov txheej txheem, zas xim yuav tsum tau tswj hwm qhov tseeb ntawm {%, thiab qhov kub thiab txias rau kev ntxhov siab sab hauv.

VI. Kev Soj Ntsuam Zoo Thiab Txheej Txheem Tswj

Tsim cov txheej txheem tshuaj xyuas kom zoo yog qhov tseem ceeb los ua kom ua tau qhov tseeb. Zaj duab xis thickness yog ntsuas siv ib qho kev ntsuas tuab tam sim no tuab tam sim no nrog qhov tseeb ntawm ± 1μm; Kev kuaj hardness yog ua siv siv microhardness tester nrog lub nra ntawm 25-50GF; thiab corrosion kuj tau soj ntsuam yog ua raws li cov txheej txheem kev tshuaj tsuag ntsev. Kev tshuaj xyuas sab nraud yog ua tau siv cov cuab yeej 3D ntsuas kev ntsuas, nrog tus yuam sij

Rau cov txheej txheem tswj, SPC cov ntsiab lus txheej txheem tswj tau siv, nrog CPK tus nqi ntawm ntau dua lossis sib npaug rau 1.33 rau cov tsis tseem ceeb. Ib qho kev ua haujlwm ruaj khov ua ke tsim tsa tau tsim kom sau cov ncauj lus kom ntxaws rau txhua pob. Ib qho IES System yog siv rau automated cov ntaub ntawv sau thiab tsom xam cov ntawv thiab kev txhim kho kom raws sijhawm thiab kev txhim kho raws kev sib txawv.

VII. Kev tswj ib puag ncig thiab cov neeg ua haujlwm

Cov txheej txheem ib puag ncig tseem ceeb cuam tshuam txog kev cuam tshuam siab high - precision ua. Qhov ntsuas kub yuav tsum tau tswj hwm ntawm 20 ± 2 degree, av noo ntawm 40-60%, thiab kev nyiam huv cov qib kawm 100,000 tus qauv. Chav fais fab hluav taws xob yuav tsum muaj kev ywj pheej los tiv thaiv kev cuam tshuam hluav taws xob hluav taws xob. Cov neeg ua haujlwm yuav tsum muaj kev cob qhia kev tshaj lij, paub lawv tus kheej cov kev ua lag luam kev ua haujlwm, thiab yauv mus ua haujlwm thiab muaj ntawv pov thawj.

Los ntawm kev siv kev ua haujlwm ntawm cov kev ntsuas kev ntsuas kev ua tau zoo, ua tiav cov hlua khi, sib ntsib ntawm cov khoom siv ua kom zoo xws li aerospace, cov cuab yeej ntsuas, thiab cov khoom siv kho qhov muag. Nrog kev nce qib ntawm automation thiab ntse thev naus laus zis thev naus laus zis yuav kho tau ntxiv, muab cov kev kho kom zoo dua kev kho rau kev tsim khoom lag luam.
