Txhawm rau ua kom tau raws li cov kev cai tshwj xeeb ntawm cov haujlwm sib txawv, peb muab ntau yam txheej txheej txheej txheej txheej txheem raws li kev nyab xeeb hauv zos thiab kev xav tau ntawm kev lag luam. Peb muab kev kho deg customized rau tag nrho peb cov khoom, raws li cov neeg siv khoom nyiam, thaum tseem muab cov lus pom zoo.
Anodizing vs. hmoov txheej
Cov lus hauv qab no qhia txog kev sib piv ncaj qha ntawm anodizing thiab hmoov txheej txheej txheej txheej txheej.
| Anodizing | Hmoov Txheej |
| Ua tau nyias nyias, txhais tau tias tsuas yog hloov me ntsis rau qhov ntev ntawm qhov. | Muaj peev xwm ua tiav cov tsho tuab, tab sis nws yog qhov nyuaj heev kom tau txais ib txheej nyias. |
| Zoo ntau yam xim hlau, nrog rau kev ua tiav. | Ntau yam txawv txawv hauv cov xim thiab textures tuaj yeem ua tiav. |
| Nrog rau cov khoom siv electrolyte kom zoo, anodizing yog ib puag ncig zoo heev. | Tsis muaj cov kuab tshuaj cuam tshuam rau hauv cov txheej txheem, ua rau nws zoo heev rau ib puag ncig. |
| Zoo heev hnav, khawb, thiab corrosion kuj. | Zoo corrosion kuj yog tias qhov saum npoo tsis sib xws thiab tsis muaj kev puas tsuaj. Tau hnav thiab khawb tau yooj yim dua li anodizing. |
| Resistant rau xim fading ntev npaum li cov xim xaiv tau haum UV tsis kam rau daim ntawv thov thiab raug kaw kom zoo. | Heev tiv taus cov xim fading, txawm tias thaum raug UV teeb. |
| Ua rau aluminium nto hluav taws xob tsis muaj hluav taws xob. | Qee qhov hluav taws xob conductivity hauv txheej tab sis tsis zoo li liab qab aluminium. |
| Yuav ua tau tus txheej txheem kim. | Ntau tus nqi-zoo dua li anodizing. |
Aluminium ib txwm tsim ib txheej nyias ntawm oxide ntawm nws qhov chaw thaum raug huab cua. Cov txheej txheem oxide no tsis muaj zog, txhais tau tias nws tsis ua rau ib puag ncig ib puag ncig - thiab nws tiv thaiv tag nrho cov hlau los ntawm cov khoom.
Anodizing
Anodizing yog kev kho saum npoo rau txhuas qhov chaw uas siv qhov zoo ntawm cov oxide txheej los ntawm thickening nws. Cov kws kho mob siv cov khoom txhuas, xws li ib qho extruded, submerge nws mus rau hauv lub da dej electrolytic, thiab khiav ib qho hluav taws xob los ntawm nws.
Los ntawm kev siv txhuas ua cov anode hauv Circuit Court, cov txheej txheem oxidation tshwm sim ntawm qhov chaw ntawm cov hlau. Nws tsim cov oxide txheej tuab dua li qhov tshwm sim ib txwm muaj.
Hmoov txheej
Hmoov txheej yog lwm hom kev ua tiav siv rau ntau yam khoom siv hlau. Cov txheej txheem no ua rau muaj kev tiv thaiv thiab kho kom zoo nkauj ntawm qhov chaw ntawm cov khoom kho.
Tsis zoo li lwm daim ntawv thov txheej (piv txwv li, pleev xim), hmoov txheej yog txheej txheem thov qhuav. Tsis siv cov kuab tshuaj, ua cov hmoov txheej txheej ib puag ncig zoo rau lwm yam kev kho kom tiav.
Tom qab ntxuav ib feem, tus kws kho mob siv cov hmoov nrog kev pab los ntawm rab phom tsuag. Cov phom no siv cov nqi hluav taws xob tsis zoo rau cov hmoov, uas ua rau nws nyiam rau cov hlau hauv av. Cov hmoov tseem txuas nrog rau cov khoom thaum nws kho nyob rau hauv qhov cub, tig cov hmoov txheej rau hauv ib qho zoo, txheej txheej.
PVDF txheej
PVDF coatings haum ntawm fluorocarbon tsev neeg ntawm cov yas, uas tsim cov ntawv cog lus uas tsis tshua muaj tshuaj lom neeg thiab thermally ruaj khov. Qhov no ua rau qee qhov PVDF txheej txheej sib txawv kom ua tau raws li qhov xav tau nruj heev (xws li AAMA 2605) nrog tsawg kawg fading nyob rau lub sijhawm ntev. Tej zaum koj yuav xav tsis thoob li cas cov txheej txheem no siv tau.
PVDF Daim Ntawv Thov Txheej Txheem
PVDF txheej rau txhuas yog siv rau hauv ib lub rooj pleev xim los ntawm cov kua tshuaj txau phom. Cov kauj ruam hauv qab no qhia tag nrho cov txheej txheem rau ua kom tiav cov txheej txheem PVDF zoo:
- Kev npaj nto- Txhua txheej txheej zoo yuav tsum tau npaj zoo. Zoo PVDF txheej adhesion yuav tsum tau ntxuav, degreasing, thiab deoxidizing (tshem xeb) aluminium nto. Superior PVDF coatings ces yuav tsum tau daim ntawv thov ntawm chrome-raws li hloov dua siab tshiab txheej yuav tsum tau thov ua ntej lub primer.
- Primer- Cov primer zoo stabilizes thiab tiv thaiv cov hlau nto thaum txhim kho adhesion rau saum txheej.
- PVDF Sab saum toj txheej- Cov xim pigment yog ntxiv nrog rau daim ntawv thov txheej txheej saum toj kawg nkaus. Sab saum toj txheej pab muab cov txheej tiv thaiv kev puas tsuaj los ntawm tshav ntuj thiab dej, nrog rau kev nce ntxiv ntawm kev puas tsuaj. Lub txheej yuav tsum tau kho tom qab cov kauj ruam no. Cov txheej txheej saum toj kawg nkaus yog txheej tuab tshaj plaws hauv PVDF txheej txheej.
- PVDF Clear Txheej- Hauv 3-txheej PVDF txheej txheej txheej txheej, txheej txheej kawg yog txheej txheej ntshiab, uas muab kev tiv thaiv ntxiv los ntawm ib puag ncig thiab tso cai rau cov xim ntawm lub tsho sab saum toj los ntawm tsis muaj kev puas tsuaj. Cov txheej txheej no kuj yuav tsum tau kho.
Yog tias xav tau rau qee yam kev siv, 2-coat lossis 4-coat txheej txheem tuaj yeem siv los hloov 3-coat txoj kev tau piav qhia saum toj no.
Cov txiaj ntsig tseem ceeb ntawm kev siv PVDF txheej
- Ntau tus phooj ywg ib puag ncig ntau dua li dip txheej, uas muaj cov tshuaj tsis haum cov organic (VOCs)
- Resistant rau hnub ci
- Resistant rau corrosion thiab chalking
- Resistant hnav thiab abrasion
- Ua kom muaj xim sib xws (tiv thaiv fading)
- Siab tsis kam mus rau tshuaj thiab kuab paug
- Ntev ntev nrog kev saib xyuas tsawg
Sib piv PVDF thiab Powder Coatings
Thawj qhov sib txawv ntawm PVDF txheej thiab hmoov txheej yog PVDF txheej:
- Siv cov tshuaj pleev xim ua kua dej, thaum cov hmoov coatings siv electrostatically siv hmoov
- Yog thinner dua cov hmoov txheej
- Muaj peev xwm kho tau ntawm chav tsev kub, thaum cov hmoov txheej yuav tsum tau ci
- Yog tiv taus tshav ntuj (UV hluav taws xob), thaum cov hmoov txheej yuav ploj mus dhau sijhawm yog tias raug
- Tsuas tuaj yeem muaj matte tiav, thaum cov hmoov txheej tuaj yeem tuaj yeem ua tiav ntau yam xim thiab ua tiav
- Cov nqi ntau dua li cov hmoov txheej, uas pheej yig dua thiab tuaj yeem txuag tau tus nqi ntxiv los ntawm kev rov siv dua cov hmoov txau
Kuv Puas Yuav Tsum Coated Architectural Aluminium Nrog PVDF?
Nws tuaj yeem nyob ntawm koj daim ntawv thov tiag tiag tab sis yog tias koj xav tau cov khoom siv ruaj khov, ib puag ncig tiv taus, thiab siv tau ntev extruded lossis dov aluminium, PVDF txheej yuav yog rau koj.
