Kev tsim cov phosphating zaj duab xis nyob ntawm ntau yam, xws li cov ntsiab lus ntawm cov tshuaj, qhov kub thiab txias, lub sijhawm, thiab lwm yam.

2. Alkaline electrolytic polishing txheej txheem rau txhuas

alkaline electrolytic polishing txheej txheem ntawm txhuas yog txheej txheem ntawm polishing nto ntawm txhuas cov ntaub ntawv los ntawm electrolysis nyob rau hauv ib tug alkaline tov. Cov txheej txheem no tuaj yeem txhim kho qhov smoothness thiab ci ntsa iab ntawm cov ntaub ntawv txhuas, thaum tshem tawm cov teeb meem me me thiab oxide txheej ntawm qhov chaw. Nyob rau hauv cov txheej txheem ntawm electrolytic polishing, txhuas ua hauj lwm raws li lub anode thiab tau txais qhov kev txiav txim ntawm tam sim no nyob rau hauv lub electrolytic cell, reacting nrog anions nyob rau hauv cov tshuaj kom ua tiav lub hom phiaj ntawm polishing. Cov nyhuv ntawm electrolytic polishing nyob ntawm seb muaj pes tsawg leeg ntawm electrolyte, tam sim no ceev, kub, thiab lwm yam.

3. Ib puag ncig tus phooj ywg tshuaj polishing ntawm txhuas thiab txhuas alloys

Ib puag ncig tus phooj ywg tshuaj polishing ntawm txhuas thiab txhuas alloys yog txheej txheem uas siv ib puag ncig tus phooj ywg chemical reagents los polish rau saum npoo ntawm cov ntaub ntawv txhuas. Piv nrog rau cov txheej txheem ntxuav cov kua qaub thiab polishing, ib puag ncig tus phooj ywg cov txheej txheem polishing siv cov tshuaj muaj kev nyab xeeb dua thiab muaj cov pa phem tsawg. Cov txheej txheem no tshem tawm cov oxide txheej thiab cov av ntawm qhov chaw ntawm txhuas los ntawm cov tshuaj tiv thaiv, thaum ua rau saum npoo du thiab tiaj tus. Qhov zoo ntawm ib puag ncig tus phooj ywg tshuaj polishing yog kev ua haujlwm yooj yim, tus nqi qis, thiab ib puag ncig tus phooj ywg.

4. Electrochemical nto ntxiv dag zog rau kev kho mob ntawm txhuas thiab nws cov alloys

Electrochemical nto ntxiv dag zog rau kev kho mob ntawm txhuas thiab nws cov alloys yog txheej txheem ntawm kev tsim cov yeeb yaj kiab ntxiv dag zog rau saum npoo ntawm cov ntaub ntawv txhuas los ntawm cov txheej txheem electrochemical. Cov zaj duab xis ntxiv dag zog no tuaj yeem txhim kho qhov tawv tawv, hnav tsis kam, thiab corrosion kuj ntawm cov ntaub ntawv txhuas. Electrochemical nto ntxiv dag zog rau kev kho mob suav nrog ntau txoj hauv kev xws li anodizing thiab micro arc oxidation. Ntawm lawv, anodizing yog ib qho ntawm feem ntau siv txoj kev, uas tsim ib tug ntom aluminium oxide zaj duab xis nyob rau saum npoo los ntawm subjecting txhuas raws li lub anode rau tam sim no nyob rau hauv lub electrolytic cell. Cov txheej ntawm alumina zaj duab xis no tsis tsuas yog muaj kev ua tau zoo heev, tab sis kuj tuaj yeem tau txais cov xim nplua nuj los ntawm kev kho mob tom ntej xws li dyeing.

5. Nto kho tshuab rau YL112 aluminium alloy

YL112 aluminium alloy nto kho tshuab yog tshwj xeeb nto kho tshuab tsim rau YL112 aluminium alloy cov ntaub ntawv. Cov thev naus laus zis no suav nrog cov kauj ruam xws li pretreatment, anodizing, thiab sealing kev kho. Kev kho mob ua ntej tsuas yog tshem tawm cov roj stains thiab oxide txheej ntawm cov ntaub ntawv txhuas, muab lub hauv paus zoo rau kev kho mob tom qab anodizing. Anodizing kev kho yog cov txheej txheem ntawm kev sib sau ua ib qho xim pleev xim rau sab nrauv ntawm txhuas hauv cov khoom siv hluav taws xob tshwj xeeb thiab cov khoom zoo nkauj. Kev kho sealing yog ib kauj ruam tom ntej ua haujlwm los txhim kho corrosion kuj thiab stability ntawm oxide zaj duab xis.

Lub hom phiaj ntawm kev kho aluminium alloy nto:

Lub hom phiaj tseem ceeb ntawm kev kho deg rau aluminium alloys yog txhawm rau txhim kho cov khoom siv corrosion, hnav tsis kam, zoo nkauj, thiab ua haujlwm. Vim yog qhov cuam tshuam ntawm aluminium alloys rau corrosion thiab hnav hauv qhov chaw siv, kev kho deg yog qhov tseem ceeb tshwj xeeb. Kev kho qhov saum npoo tuaj yeem txhim kho corrosion kuj ntawm aluminium alloys thiab txhim kho lawv lub neej kev pab cuam; Tib lub sijhawm, nws tuaj yeem txhim kho qhov hnav tsis kam ntawm aluminium alloys thiab txhim kho lawv cov hnav tsis kam; Tsis tas li ntawd, los ntawm kev kho saum npoo av, aluminium alloys tuaj yeem tau txais txiaj ntsig nrog kev zoo nkauj tshiab thiab kev ua haujlwm kom tau raws li qhov xav tau ntawm ntau qhov chaw.

1. Kev tiv thaiv saum npoo ntawm aluminium alloy: Kev kho deg tuaj yeem tiv thaiv qhov chaw ntawm aluminium alloy los ntawm ib puag ncig ib puag ncig xws li huab cua ntub, ultraviolet hluav taws xob, tshuaj, thiab lwm yam, txhim kho corrosion kuj thiab huab cua tsis kam ntawm aluminium alloy.
