Kab lus piav qhia qhov anodized aluminium profile yog dab tsi. Nws tau qhia tias anodizing yog dab tsi thiab yuav ua li cas cov txheej txheem thev naus laus zis no tau ua tiav. Ib qho ntxiv, cov ntaub ntawv tau muab qhia txog kev siv cov khoom anodized, qhov twg lawv xav tau.
Nws yog dab tsi?
Ib tus neeg twg uas tau kawm txog tshuaj lom neeg zoo hauv tsev kawm ntawv yuav nco ntsoov tias txhuas yog ib txwm muaj txheej nrog zaj duab xis nyias. Nws tshwm sim thaum cov hlau nkag mus rau cov pa oxygen, uas txhais tau tias tsis muaj txoj hauv kev kom zam nws qhov tsos. Qee lub sijhawm tshwj xeeb tau ua kom tshem tawm cov khoom hlau ib ntus ntawm cov yeeb yaj kiab no, piv txwv li, ua ntej siv vuam . Txawm li cas los xij, cov kws tshaj lij tau pom tias cov txheej txheem no, nrog rau qhov tsis zoo, tseem nqa qee yam khoom zoo. Raws li lawv qhov kev tshawb fawb, nws muaj peev xwm tsim cov khoom lag luam zoo li anodized aluminium profile.
Cov txheej txheej tawv tawv dua li cov hlau ntshiab thiab txawm tias feem ntau ntawm nws cov hlau phom siv hauv lub neej niaj hnub . Cov qib hnav tsis kam kuj tseem siab dua. Lwm qhov txiaj ntsig tseem ceeb yog qhov yooj yim ntawm kev siv cov organic-based dyes, vim tias zaj duab xis muaj ntau qhov hws. Qhov xwm txheej no tseem ceeb heev rau cov khoom tsim khoom thiab tus kheej cov khoom uas tau tsim los kom muaj kev txhim kho kom zoo nkauj. Cov txheej txheem ntawm kev siv cov yeeb yaj kiab nws tus kheej cuam tshuam nrog kev siv cov txheej txheem hluav taws xob (tab sis ntau ntxiv tom qab ntawd).
Hauv ntau qhov xwm txheej, cov txheej txheem anodized profile muaj qhov ua tiav cov nyiaj zoo lossis ua tiav cov xim dub zoo nkauj - uas ua rau nws muaj peev xwm yuav luag ib txwm txiav txim qhov tseeb ntawm anodizing. Tom qab kev ua tiav, cov khoom siv tau ruaj khov dua thiab ruaj khov. Cov kws tshaj lij kuj tseem ceeb tias nws siv tau nyab xeeb dua li siv cov tshuaj ib txwm tsis muaj txheej ntxiv.
Nws tau pom tias anodized profile yooj yim dua los tswj kom huv thiab huv si. Nws zoo kawg nkaus tiv taus txawm tias cuam tshuam los ntawm cov av noo siab thiab lwm yam tsis zoo.
Kev siv tshuab ntau lawm
Lub npe heev "anodizing" yog vim qhov tseeb tias hauv kev ua haujlwm txheej txheem npog nrog zaj duab xis tshwj xeeb dhau los ua anode. Feem ntau ntawm cov kws tshaj lij xaiv siv dilute sulfuric acid ua qhov nruab nrab tseem ceeb. Nws cov qib saturation tuaj yeem ncav cuag 20%. Kev siv cov ncaj qha tam sim no kuj tseem muaj feem cuam tshuam. Nws lub zog yuav tsum yog los ntawm 1 txog 2.5 A rau 1 dm2, thaum siv qhov hloov pauv tam sim no, yuav tsum tau siv zog 3 A rau 1 dm2.
Tus qauv ua haujlwm kub txog 20-22 degrees . Kev sib txawv ntawm nws yuav tsum tau txhawb los ntawm kev txiav txim siab tshwj xeeb. Hauv qhov tshwj xeeb electroplating da dej, anodes (yog, lawv feem ntau ua tiav ib zaug hauv tus lej loj kom nrawm dua thiab ua kom yooj yim rau cov txheej txheem) tuaj yeem kho lossis tshem tawm. Cov cuab yeej siv nrog cov nqi hluav taws xob tsis sib xws feem ntau yog cov hlau lead, txawm hais tias qee zaum cov qib reagent qib txhuas daim hlau tau siv.
Tseem ceeb: thaj chaw ua haujlwm thiab thaj chaw ua haujlwm txuas yuav tsum zoo ib yam, txwv tsis pub koj suav tsis tau qhov txiaj ntsig zoo.
Nws muaj peev xwm txo qis cov txheej electrolyte cais cov cuab yeej tseem ceeb thiab cov haujlwm ua haujlwm tsuas yog txog qee qhov txwv, txwv tsis pub qhov ua haujlwm tau zoo dua . Nws yuav tsum nkag siab tias cov ntsiab lus kho ntawm cov khoom ua haujlwm tsis tuaj yeem npog nrog txheej tiv thaiv. Lub ntsiab lus no yuav tsum tau sib tham ua ntej. Pendants lossis clamps tsis tuaj yeem raug tshem tawm, lawv yuav nyob li qub kom txog thaum kawg ntawm cov txheej txheem.
Lub sijhawm anodizing cuam tshuam ncaj qha rau qhov ntev ntawm cov khoom. Qee zaum lawv tuaj yeem npog nrog zaj duab xis tiv thaiv hauv 15 feeb. Cov khoom loj feem ntau siv sijhawm li 60 feeb los ua. Thaum cov workpieces raug tshem tawm, lawv raug ntxuav hauv dej ntws. Ib qho ntxiv, kev ua kom tsis muaj tshuaj lom nyob hauv chav da dej tshwj xeeb nrog kev pab ntawm ammonia, thiab tom qab ntawd yuav tsum tau yaug dua; qee zaum kev pabcuam tiav yog ua tiav.
Lwm cov electrolytes tuaj yeem siv nrog rau sulfuric acid. Cov hauv paus ntsiab lus thev naus laus zis tsis txawv, qhov kev txhawj xeeb tsuas yog hloov pauv:
- yam ntxwv ntawm cov khoom siv tam sim no;
- lub sijhawm ntawm cov txheej txheem;
- cov txheej txheej dav dav.
Kev ua tiav yog ua nyob ib puag ncig:
- oxalic acid;
- orthophosphoric;
- chrome;
- ua ke cov organic electrolyte.
Scope ntawm daim ntawv thov
Txoj haujlwm tseem ceeb tshaj plaws uas tau daws thaum anodizing aluminium profile yog txhawm rau txhim kho nws qhov kev tiv thaiv tsis zoo rau ib puag ncig. Yog li ntawd, cov khoom lag luam zoo li xav tau hauv ntau qhov chaw thiab feem ntau siv raws li:
- cov khoom zoo nkauj hauv cov tsev thiab cov qauv;
- cov paib qhia kev;
- cov qauv tshaj tawm;
- qhia sawv;
- tsheb kauj vab ntas;
- railings;
- tsom teeb;
- tuav tes;
- taug kev nce ntaiv thiab cov neeg taug kev;
- rooj zaum;
- knitting koob;
- qhov chaw ntawm tsheb thiab tsheb;
- cua sov reflectors;
- pistons;
- ntas rau partitions thiab cov ntxaij vab tshaus.
