Chii chinonzi pamusoro pekurapa kwealuminium profile?

Mushonga wepamusoro unosanganisira chifukidziro kana muitiro wekuti chifukidziro chinoshandiswa kune kana muzvinyorwa.Kune akasiyana ekurapa epamusoro anowanikwa ealuminium, imwe neimwe iine zvinangwa zvayo uye mashandisiro anoshanda, sekuve anoyevedza, anonamira zvirinani, kana corrosion resistant, nezvimwe.

Nekuramba kuchivandudzwa kwemararamiro evanhu, zvinodikanwa zvekutaridzika uye ruvara rwemagonhi nemahwindo zviri kuramba zvichikwira, uye nekunatsiridza zvishoma nezvishoma kwealuminum yekugadzira tekinoroji, kumwe kurapwa kwakaoma kwepasi kwave kubudirira.Iyo aluminium pamusoro pekurapa maitiro atinowanzo kuona anosanganisira electrophoresis, anodizing, poda coating, PVDF coating, huni tsanga zvichingodaro.

1. Electrophoresis

Electrophoresis ndiyo electrophoretic coating pane cathode uye anode.Pasi pechiito chevoltage, iyo inochaja yekubatisa ion inoenda kune cathode uye inodyidzana nealkalinity inogadzirwa pane cathode pamusoro kuti igadzire zvisinganyungudika zvinhu, izvo zvinoiswa pamusoro peiyo workpiece.Aluminium profile electrophoresis inoreva maitiro ekuisa iyo extruded aruminiyamu alloy mu electrophoresis tank, uye kugadzira dense resin firimu pamusoro mushure mekupfuura neakananga ikozvino.Electrophoretic aluminium profiles inopenya zvakanyanya uye ine girazi mhedzisiro, iyo inovandudzawo kusagadzikana kwekuora.
Process Flow:

Electrolysis (kuora) ➤ Electrophoresis (kutama, kutama) ➤ Electrodeposition (kunaya) ➤ Electroosmosis (kupererwa nemvura)

2. Anodizing

Anodized aluminium profiles inoreva maitiro ayo aruminiyamu uye alloys ayo anoumba oxide firimu pane aruminiyamu zvigadzirwa (anodes) pasi peiyo inoenderana electrolyte uye chaiwo maitiro mamiriro pasi pechiito cheyakaiswa ikozvino.Nekudaro, iyo oxide firimu inoumbwa pamusoro peanodized aluminium yakasiyana neyakajairwa oxide firimu, uye anodized aluminium inogona kudhayiwa ne electrolytic coloring.Kuti ukunde hurema hwealuminium alloy pamusoro kuoma, kusapfeka, nezvimwewo, kuwedzera huwandu hwekushandisa, uye kurebesa hupenyu hwesevhisi, tekinoroji yekurapwa kwepamusoro yave chinongedzo chakakosha mukushandiswa kwealuminium alloys, uye anodic oxidation tekinoroji. parizvino ndiyo inonyanya kushandiswa uye yakabudirira.ye.

Process Flow:

Kubvisa mafuta ➤ Chemical Polishing ➤ Acid Corrosion ➤ Stripping Black Film ➤ Anodizing ➤ Pre-Dyeing Treatment ➤ Kudhaya ➤ Kuvharira ➤ Kuomesa

Musiyano uripo pakati peanodizing uye electrophoresis: anodizing inoiswa oxidized kutanga yozoiswa ruvara, nepo electrophoresis yakanyatso ruvara.

3. Poda yehupfu

Shandisa electrostatic poda yekupfapfaidza midziyo yekupfapfaidza iyo poda yekuputira pamusoro peiyo workpiece.Pasi pekuita kwesimba remagetsi, hupfu huchave hwakafanana adsorbed pamusoro pechiso chebasa rekuita kuti rigadzire poda yehupfu.Yakasiyana-siyana yekupedzisira coatings.Mhedzisiro yekupfapfaidza yakakwira zvakanyanya kune yekupfapfaidza maitiro maererano nemagetsi simba, adhesion, corrosion resistance, uye kuchembera kuramba.

Process Flow:

Pamberi pekurapwa ➤ kumwaya ➤ kubika mushonga

4. PVDF Coating

PVDF Coating imhando yekupfapfaidza kwemagetsi, inovawo nzira yekupfapfaidza mvura.Iyo fluorocarbon yakapfapfaidza coating inoshandiswa ndeyekubikira polyvinylidene fluoride resin sechinhu chepasi kana nesimbi aruminiyamu poda semuvara.Kune dzakamiswa uye semi-yakamiswa mhando.Iyo yakamiswa mhando ndeye pre-kurapwa uye kupfapfaidza yealuminium zvinhu, uye zvigadzirwa zvealuminium zvinomiswa panguva yekurapa.Iyo yemhando yepamusoro yefluorocarbon coating ine simbi inopenya, yakajeka mavara uye ari pachena matatu-dimensional maitiro.

Process Flow:

Magadzirirwo asati aitwa kurapa: kubvisa uye kusvibisa aruminiyamu ➤ kugeza ➤ alkali washing (kubvisa mafuta) ➤ kugeza ➤ pickling ➤ kugeza ➤ chromizing ➤ kugeza ➤ kugeza mvura yakachena

Kupfapfaidza: kupfapfaidza primer ➤ topcoat ➤ pendi yekupedzisa ➤ kubheka (180-250℃) ➤ kuongorora kunaka

Musiyano pakati pe electrostatic poda kupfapfaidza uye fluorocarbon spraying: poda kupfapfaidza kushandisa poda spraying michina (electrostatic spraying muchina) kupfapfaidza upfu unhani pamusoro pemvura workpiece.Pasi pechiito chemagetsi akamira, hupfu huchave hwakafanana adsorbed pamusoro peiyo workpiece kuti igadzire poda coating layer.Fluorocarbon spraying imhando yekupfapfaidza kwemagetsi, inovawo nzira yekupfapfaidza mvura.Inonzi fluorocarbon spraying, uye inonzi curium oil kuHong Kong.

5. Zviyo zvehuni

Huni yekufambisa zviyo profil yakavakirwa pakupfapfaidza poda kana electrophoretic pendi, zvinoenderana nemusimboti wekushisa kwepamusoro sublimation kupisa kupinza, kuburikidza nekupisa uye kudzvanywa, iyo huni yezviyo pateni papepa rekutamisa kana firimu rekutamisa rinokurumidza kutamiswa uye kupinda kune maprofiles ane yakapfapfaidzwa kana electrophoresis.Iyo yehuni-zviyo profil inogadzirwa ine yakajeka magadzirirwo, akasimba matatu-dimensional maitiro, uye anogona kuratidza zviri nani manzwiro echisikigo ezviyo zvehuni.Icho chinhu chakanaka chekuchengetedza simba uye zvakatipoteredza kutsiva huni hwechinyakare.

Process Flow:

Sarudza substrate ➤ Peta bepa rekudhinda zvehuni ➤ Kavha bhegi repurasitiki ➤ Vacuyumu ➤ Kubika ➤ Kubvarura bepa rekudhinda ➤ Chenesa pasi

Rui Qifeng anogona kubata nekubata kwakasiyana kwakaomarara kwepamusoro kurapwa kwezvinhu zvekuvaka.Hunhu hwepamusoro uye mitengo inonzwisisika, tinogamuchirwa kuti uwedzere kubvunza.
