Aluminium Finish: Technology thiab tswv yim

Painting txhuas thiab lwm yam nonferrous co yog txuam nrog ib co teeb meem muaj feem xyuam rau ceev ceev oxidation. Nyob rau hauv tus ntawm cov pa, ib tug oxide zaj duab xis yog tsim nyob rau hauv ib cov ntaub ntawv uas uas minimizes adhesion ntawm tej txheej, xws li xim tsev thiab primers. Vim hais tias ntawm koj tus kheej no-coloring yog feem ntau luv luv-lived thiab tsis zoo nyob rau hauv qhov zoo tshaj plaws txoj kev.

anodizing

Txawm tias cov niaj hnub ntau yam ntawm primer compositions, lawv tsis muab qhov kev kawm ua hauj lwm, thiab cov xim muaj hlau dhas tawm ib tug txheej ntawm lub slightest kev cuam tshuam.

Yuav kom txhim kho txoj kev adhesion ntawm cov xim muaj hlau thiab txhuas chaw yuav ua tau los ntawm txoj kev anodizing cov hlau. Qhov no txoj kev muaj nyob rau hauv ib tug electrochemical los yog tshuaj kho mob, vim uas txo oxidation siv. Yuav luag tag nrho cov khoom uas tsis yog-ferrous co, coloring nyob rau hauv industrial tej yam kev mob, kis tau los ntawm cov anodizing rau tshwj xeeb pab kiag li lawm.

Ntaub ntawv thiab cov cuab yeej

Tom tsev, koj yuav tau nqa tawm txoj kev ua no los yog siv tshwj xeeb ib tug primer. Hmoov txheej txhuas nrog Anodized yuav siv sij hawm ntau lub sij hawm thiab tsub kom tus nqi, tab sis cov no tsim nyog lub dag zog. Pre-yuav tsum tau npaj cov cuab yeej thiab cov ntaub ntawv, tsis muaj uas nws yog tsis yooj yim sua kom ua tau ib tug ruaj thiab high-zoo finishes:

• tsuag, cov menyuam los yog txhuam;
• ntwav txhuam ntoo nrog ib tug nplua grain loj (yuav tsum tau rau txhuas matting nto);
• ntim rau kev tso kawm ntawm qhov chaw yuav tsum tau kho;
• vinegar rau dilute cov xim muaj hlau muaj pes tsawg leeg;
• aniline;
• txhais tau tias rau degreasing;
• electrolytic muaj pes tsawg leeg cov khoom xyaw (dej, ntsev, ci dej qab zib).

kev kawm ua hauj lwm

Aluminium Xim khoom xyaw pib nrog compound rau lub electrolytic muaj pes tsawg leeg thiab kev npaj ntawm cov tshuaj. Cov nqi ntawm cov dej yuav tsum txaus rau tag nrho cov immersion txhuas lub caij. Cov uas ua kua yog poured mus rau hauv ob tug zoo tib ntim. Ib tug ntawm lawv yog sau dej qab zib nyob rau hauv ib qho ratio ntawm 1 mus rau 5 (dej qab zib thiab dej, ntsig txog), lwm ntsev ntxiv nyob rau hauv tib lub npaum li cas. Ces cov kua twb do kom txog thaum tiav xaus ntawm lub additives. Cov kauj ruam tom ntej yog filtering pes tsawg leeg thiab ib tug compound ntawm ob hlab ntsha. Cov tshuaj yuav tsum sawv ntsug nyob rau lub sij hawm no nws yog ua tau los kho tau cov hlau nto. Roj thiab cov av raug muab tshem tawm nrog ib daim ntaub soaked nyob rau hauv acetone.

Ntxiv mus, tus neeg hais yog rinsed nyob rau hauv khiav dej thiab muab tso rau hauv ib lub taub ntim nrog ib tug daws. Koj thawj zaug yuav tsum hnav hnab looj tes rau kev ruaj ntseg.

Cov tsis zoo davhlau ya nyob twg yog kev cob cog rua rau ib tug submerged qhov chaw muaj peev xwm, zoo - ncaj qha mus rau lub ntsiab rau lawv tus kheej. Anodizing tseem rau 2-3 teev kom txog rau thaum ib tug blue-grey zas.

Tsis tas li ntawd, tej zaum nws yuav tsum ua los ntawm txhuas dyeing nyob rau hauv tsev. Lub coloring muaj pes tsawg leeg muaj xws li ntawm 1 liter ntawm kua, 20 grams aniline zas xim thiab 2 ml ntawm vinegar. Cov tshuaj yuav tsum tau rhuab mus rau 80 degrees nrog tas mus li stirring. Cov khoom uas muaj dhau los ntawm lub anodizing txheej txheem yog muab tso rau hauv ib lub taub ntim nrog ib tug coloring muaj pes tsawg leeg rau 15-20 feeb.

Aluminium Xim: Technology

Anodizing tsis yog ib tug yuav tsum-saib lo lus uas peb. Yog hais tias tsim nyog, koj muaj peev xwm ua tsis muaj txoj kev ua no, siv cov primer, uas tso cai rau kom qhov zoo tshaj ntawm cov xim muaj hlau adhesion thiab hlau. txhuas pleev xim rau nrog primer yog ua los ntawm kev siv hauv qab no cov ntaub ntawv thiab cov cuab yeej:

• kerosene, acetone, thiab lwm yam txhais tau tias rau degreasing;
• Tshwj xeeb xim rau hlau;
• primer rau alkyd;
• ntwav txhuam ntoo;
• cov menyuam los yog txhuam.

Aluminium Xim tsev pib nrog kho rau qhov chaw nrog ntwav txhuam ntoo ua rau kom cov adhesion primer. Qhov zoo tshaj plaws kev xaiv yuav ua tau ib tug abrasive nrog ib tug nruab nrab txheej. Tom qab ceev faj sib tsoo khoom yog kho nrog acetone nrog ib daim ntaub, muaj plaub-free daim ntaub. Yuav kom tiv thaiv cov tawv nqaij ntawm ob txhais tes yog tsim nyog los siv hnab looj tes.

Tom ntej no, nyob rau ntawm qhov chaw luam. Nyob rau hauv cov ntaub ntawv no, koj yuav tsum mus faib nws sai sai thiab sai li sai tau tom qab qhov kev kho mob, vim nws muaj feem xyuam rau cov durability thiab kev cia siab ntawm lub txheej. Nws yog pom zoo kom npaj lub primer ua ntej koj pib sanding qhov chaw. Streaks thiab irregularities uas muaj arisen, tom qab ua ntawv thov cov primer, yuav raug tshem tawm los ntawm txoj kev sanding ntawv.

Aluminium Xim no yog ua nyob rau hauv tsawg kawg yog ob khaubncaws sab nraud povtseg, nyob rau ua ntej rau daim ntawv thov ntawm txhua tus ua ntej txheej yuav tsum kiag qhuav.

hmoov coatings

Rau coloring txhuas hmoov muaj pes tsawg leeg kuj yog siv. Nws muab ib tug txhim khu kev qha check txheej nyob rau hauv daim ntawv ntawm ib tug monolithic txheej, tsis tsuas beautifies cov khoom, tab sis kuj txo qhov yuav ua rau corrosion.

Thawj kauj ruam yog npaj qhov chaw. Nyob rau hauv industrial tej yam kev mob nrog qhov chaw muab tshem tawm ntsev thiab impurities, thiab ces rinsed nrog dej. Dhau li ntawm tus txheem degreasing txhuas hmoov xim txheej muaj xws li phosphate, uas tsub kom qhov zoo tshaj ntawm cov hlau thiab xim adhesion.

Ces lub ntsiab yog raug rau kom qhuav nyob rau hauv tus ntawm high kub thiab txias. Ntawm kev tseem ceeb yog lub polymerization txheej txheem, uas muaj nyob rau hauv thov ib tug tshwj xeeb cob txheej nyob rau hauv cov huab cua siab. Lub chaw ua hauj lwm yog ua li cas nrog rau cov kev pab los ntawm lub electrostatic atomizer txoj kev ua nyias txheej nyob rau hauv qhov chaw.

Tom qab inking txhuas khoom uas muab tso rau hauv ib tug tshwj xeeb cua sov thiab rhuab rau 200 degrees rau 10-15 feeb. Tua ntawm tus txheej tshwm sim thaum lub sij hawm txias ntawm cov hlau.

Cov kev siv tshwj xeeb cov cuab yeej thiab furnaces complicates tus txheej txheem ntawm painting rau cov hmoov formulations nyob rau hauv lub tsev, uas yog vim li cas nws yog feem ntau hloov los ntawm anodizing.

Hmoov txheej tau nyob rau hauv tej txhuas yam. Cov feem ntau lug mas yuav kis tau tus txheej txheem rau txheej qhov chaw uas yog npaj rau kev siv ntawm kub txog li 220 degrees.

coloring tsuag

Ua ntej daim ntawv thov ntawm no technology siv ib tug txheej txheem cov ntaub ntawv uas npaj, rau Piv txwv li nyob rau hauv anodizing. Ntxiv nta muaj nqis ntsoov teev yuav tsum tau soj ntsuam txaus ncua deb ntawm tus nto thiab lub zais pa, thiab thov ib tug plurality ntawm khaubncaws sab nraud povtseg. Txij li thaum lub yav dhau los txheej deposition yuav tsum muaj tsawg kawg yog 20 feeb, tab sis tom qab ntawd tej zaum yuav loj rau cov nram no xim txheej. Cov nab npawb ntawm cov khaubncaws sab nraud povtseg mas nws txawv ntawm painting khoom zoo thiab cov lag luam kom paub meej. Nyob rau nruab nrab, nws yuav sib txawv nyob rau hauv cov kab 3-15 depositions.

nta

Nws yog ib qho tseem ceeb tsis tau hnov qab txog tus nyob tuav lub tog raj kheej, nws yuav pab tau kom tsis txhob txia thiab stains. Nyob rau hauv tej rooj plaub muaj tej zaum yuav txhaws ntawm lub nozzle. Rau tu nws yog tsim nyog los tig lub raj mis thiab txau cov muaj pes tsawg leeg rau lub point, kom txog thaum ib tug pob tshab muaj pes tsawg leeg yuav tshwm sim.

Tom qab kawm tiav ntawm cov xim nyob rau hauv lub xub ntiag ntawm residues yuav tsum tau muab tshem tawm rau ib qho chaw muaj kev tiv thaiv los ntawm tshav ntuj. Cov cuab yeej siv yog ntxuav nrog ib tug hnyav. Painting ntawm txhuas nyob rau hauv ib tug zoo li yam, tsis hais txog ntawm cov ntaub ntawv uas siv rau cov hauj lwm.

yam xim

Cov tshwm sim zaum kawg yog los ntawm tsis tsuas ua tau raws li nrog tag nrho cov subtleties ntawm kev ua hauj lwm, tab sis kuj zoo thiab cov yam ntxwv ntawm lub xim. Qhov tseem ntau lub xeev muaj ob peb qho kev xaiv:

• Ib tug acrylic muaj pes tsawg leeg raws resistant rau kev puas tsuaj los ntawm dej thiab huab kub. Xim yog thov tshaj lub primer txheej.
• Epoxy manufactured siv tshwj xeeb resins, vim uas nws muaj cov yam ntxwv xws li durability thiab lub dag lub zog.
• Aniline yog Ameslikas tsim rau cov textile kev lag luam. Qhov no xim yog zoo tagnrho rau txhuas khoom uas hais tias tau dhau lub anodization txheej txheem. Tab sis nws tsis yog tsis muaj drawbacks, nyob rau hauv particular, muaj pes tsawg leeg muaj tsawg kuj mus ya raws thiab tshav ntuj.
