Ivakavuvuli kei na kena vakayagataki na tekinolaji ni photophoresis ni extinction

1. Tekinolaji ni Matte Electrophoretic

Matte electrophoretic technology is a specialized electrophoretic coating process for aluminium profile surface treatment. E vakavuna e dua na lowgloss matte se satin finish mai na resin matting principles while offering excellent weather resistance, veisaqasaqa ni corrosion, kei na cakacaka ni veika bula. Na tikina bibi e oka kina:

Technical Principle

Na uto ni matte electrophoresis e koto ena kena rawati na diffuse reflection via resin matting:

Resin Matting: Vakayagataka na duidui vakalivaliva ena kedrau maliwa na resins ni bonding me bulia na veitikina ni microgel insoluble ena iyaloyalo ni coating. Na veisau ena idusidusi ni refractive ena iyaloyalo yavala e vakavuna na vakanananu diffuse me baleta e dua na revurevu matte.

Bibi ni Molecular: Matte electrophoretic paint has a higher molecular weight (70,000–80,000 g/mol) Vakatauvatani kei na glossy electrophoresis (25,000–40,000 g/mol), ka vakavuna na iyaloyalo vavaku ka kaukauwa cake.

Production Process

Na veikalawa tudei:

1. Veiqaravi taumada: Degreasing, vakasavasavataki alkaline/acid, Neutralization, kei na vakasavasavataki.
2. Anodizing: Anodizing ni sulfuric acid (10–12 μm na vavaku ni iyaloyalo).
3. Rokataki: Singlenickel salt coloring determine final hue.
4. Vakasavasavataki: Katakata (60–80°C) kei na wai batabata savasava (conductivity <50 μS/cm).
5. Electrophoresis: 180–250V voltage, 20–25°C, 2–5 na miniti (15–20 μm coating).
6. Veivakabulai: 160–190°C me 30–40 na miniti (kaukauwa ni iyaloyalo: 4–5H).

 

Veika e Yaco

Gloss Lailai: 60° yaga ni gloss <30 GU, vakalailaitaka na dukadukali ni rarama.

Veisaqasaqa ni Draki: 8,000+ auwa ena vakatotolotaki ni vakatovotovo (vs. 1,500–4,500 na auwa me baleta na coatings tudei).

EcoFriendly: E yavutaki ena wai, lailai na kaburaki ni VOC.

Vakasavasavataki koya: Stainresistant surface.

 

2. Aluminum Anodizing Technology

Anodizing is an electrochemical process that generate a dense oxide layer (Al₂O₃) ena dela ni aluminium, Vakatorocaketaka na veisaqasaqa ni corrosion, Veisaqasaqa ni daramaka, kei na aesthetics.

iVakavuvuli ni Cakacaka

Electrochemistry: Aluminium e cakacaka me anode ena dua na electrolyte acidic (e.g., sulfuric acid):

Anode: \( 2O Al + 3H_2O rightarrow Al_2O_3 + 6H^+ + 6e^ \)

Cathode: \( 6H^+ + 6e^ rightarrow 3H_2↑ \)

Layer Structure:

Itatarovi ni itatarovi: Compact inner layer (0.01–0.1 μm).

Porous Layer: Vale e tautuba ni honeycomb (10%–30% porosity).

Drodro ni iwalewale

1. Veiqaravi taumada: Degreasing → Alkaline etching → Neutralization.
2. Anodizing:

Electrolyte: 15%–20% sulfuric acid.

iVakatagedegede: 12–20V, 1–2 A/dm², 18–22°C, 30–60 miniti (5–25 μm vavaku).

3. Rokataki (Digitaki):

Electrolytic: Masima kaukamea (Ni, Sn) me baleta na varasa/loaloa.

Na Vakarokoroko: Organic dyes for colors.

4. Veivauci: Wai katakata (90–100°C) se iwali batabata ni Ni/F.
