Amashanyarazi yahanaguweho Aluminiyumu kubikoresho bikoreshwa: Ibyingenzi bya tekinike

Amabuye asukuye ya aluminiyumu ni ibikoresho by'ibanze byo mu rugo rwohejuru ibikoresho byo mu rugo (urugero, firigo, amashyiga, ingofero, hamwe na konderasi). Bitandukanye na aluminiyumu isanzwe isukuye, igomba kuba yujuje ubuziranenge bwo kugaragara, kuramba, gutunganywa, no kubahiriza ibidukikije kugira ngo ihuze n’ibidukikije bigoye (ubushyuhe bwinshi, ubushuhe, imyotsi y’amavuta) hamwe n’ibitekerezo by’abaguzi ku miterere n’ubuziranenge. Hano haribintu byingenzi byingenzi bisabwa.

1. Kugaragara Kugaragara Kugaragara & Guhuza Imiterere

Ubwiza bwibonekeje kandi bwitondewe bugena byimazeyo ibyiyumvo byibikoresho byo murugo, hamwe no kwihanganira zeru kubusembwa bukomeye.

Imyenda isukuye imwe

• Imirongo yimisatsi iterekanwa (0.05–0.1mm z'ubugari) igomba guhoraho, ihamye mubwimbitse, kandi idafite imirongo yamenetse, imirongo, cyangwa ingano zingana. Nta bishushanyo bigaragara, amenyo, cyangwa inenge ku cyiciro A (nyamukuru kigaragara) hejuru.

Kugenzura Indabyo & Ibara

• Urumuri ruto-ruciriritse (60-90 GU) kugirango rurangire neza, rutagaragaza; ibara rihoraho muri ΔE≤1.5 kugirango wirinde icyiciro-cy-chromatic aberration. Indangururamajwi zirimo inyenyeri ya feza, umukara wa matte, na champagne zahabu.

Kurwanya Urutoki & Byoroshye-Kuri-Isuku

• Igikoresho cyihariye cyo kurwanya urutoki (urugero, oleophobic resin) cyemeza ko urutoki, irangi ryamavuta, n ivumbi bishobora guhanagurwa nigitambaro cyumye, bikomeza kugaragara neza mubikoni birimo amavuta.

Ubuso

• Ra≤1.6μm kugirango ikorwe neza, yoroshye idafite impande zikarishye.

2. Kuramba Kuruta Ibikoni Bikomeye

Ahabanza pan Ibikoresho bigomba kwihanganira igihe kirekire cyamavuta, ubushuhe, ubushyuhe bwinshi, hamwe no guterana burimunsi nta kwangirika.

Kurwanya ruswa nziza cyane:

• Ikizamini cyo gutera umunyu: hours300 amasaha (NSS itabogamye) idafite ingese cyangwa igipfundikizo.

• Kurwanya acide, alkalis, hamwe nogukoresha ibikoresho: Ntabwo byatewe nabasukura igikoni gisanzwe (pH 4-10); nta ibara cyangwa gukuramo nyuma yo kwibiza amasaha 24.

• Kurwanya ubuhehere: Nta shusho cyangwa okiside nyuma yamasaha 500 kuri 85 ° C na 95% RH.

Kwambara Kwinshi & Kurwanya Kurwanya:

• Gukomera cyane: ≥2H (ikaramu yikaramu) kugirango wirinde ibishushanyo bya buri munsi biturutse ku isuku cyangwa guhura.

• Kurwanya abrasion:, 000 5.000 cycle (Ikizamini cya Taber) hamwe no kwambara gake kandi ntagaragazwa na substrate ya aluminium.

• Ubushyuhe bwumuriro: Ihangane -40 ° C kugeza kuri 120 ° C utarinze gutwikirwa, guturika, cyangwa guhindura ibara - birakenewe cyane ku ziko no gufunga.

3. Gusobanura neza ibipimo bifatika kandi bitunganijwe

Ikibaho gisaba kwihanganira byimazeyo guterana hamwe no gushiraho (kunama, kashe) nta byangiritse.

Ubworoherane

• Umubyimba (0.4–1.0mm) ± 0.02mm; uburinganire ≤0.5mm / m kugirango wemeze neza hamwe nibikoresho bikoreshwa.

Imiterere ihebuje:

• T-kugoreka: 0–1T (nta gutwikisha ibice nyuma ya 180 ° yunamye).

• Kurambura: ≥8% yo kurwanya kashe no gushushanya byimbitse udatanyaguye.

Ibikoresho bya mashini bihamye

• Imbaraga zingana 115–165N / mm⊃2 ;; gutanga umusaruro ≥100N / mm² yo gutunganya buri gihe.

  4. Substrate-Yera-Yuzuye & Coating Quality

  Sisitemu shingiro ya aluminium na coating igena kuramba kuramba no gukora.

  Guhitamo Amavuta

• Ahanini 1xxx (aluminiyumu yera, urugero, 1050/1100) cyangwa 3xxx (aluminium-manganese, urugero, 3003) ibivanze - biremereye, byoroshye, kandi birwanya ruswa.

  Kwerekana ubuziranenge

• Nta pinholes, ibiyirimo, cyangwa okiside yo hejuru; imiterere yintete imwe yo gukaraba neza.

Sisitemu yo gutwikira:

• Primer: Epoxy resin (5-10 mm) kugirango ifatanye cyane kandi irinde ruswa.

• Ikoti hejuru: Polyester ( PE ) cyangwa fluorocarubone ( PVDF , 20-30 mm) kugirango irwanya ikirere kandi ituze amabara; PVDF ikunzwe kubikoresho byo murwego rwohejuru.

• Adhesion: ≥Icyiciro 0 (ikizamini cyambukiranya) kugirango wirinde gukuramo mugihe cyo gutunganya cyangwa gukoresha.

5. Kubahiriza ibidukikije

Kubahiriza amahame y’ibidukikije ku isi ni itegeko ku bikoresho byo mu rugo.

Kwubahiriza RoHS

• Ubuntu bwa sisitemu, mercure, kadmium, chromium ya hexavalent, PBBs, na PBDEs.

VOC yo hasi & Formaldehyde

• Ibidukikije byangiza ibidukikije bifite imyuka ya zeru ya ferdehide hamwe na VOC <100g / L, guhura na GB 18585 na EU EN 71-3.

100%

• Aluminium substrate hamwe nigitambaro birashobora gukoreshwa neza, bigahuza nintego zirambye zo gukora.

Umwanzuro

Amabuye yogejwe ya aluminiyumu kubikoresho byo munzu nibikoresho byo murwego rwohejuru bihuza igishushanyo mbonera, kuramba, no kurengera ibidukikije. Ibisabwa byihariye byibanda ku guhuza imiterere, kurwanya urutoki byoroshye gusukura, kwangirika / kwambara, gutunganya neza, no kubahiriza icyatsi - ibyo byose ni ingenzi mu kuzamura ubuziranenge n’isoko ry’ibikoresho byo mu rugo.

Niba ukeneye ibicuruzwa bya aluminium coil / urupapuro, nyamuneka twandikire kugirango tuganire byinshi.

Dingang Irangi rya aluminiyumu ni choie yawe nziza mugace kibyara umusaruro.

Dingang - Uruganda rwumwuga Kumurongo wa Aluminium Alloy Coating Umuzingo wa aluminiyumu / Urupapuro Kuva 2002

Murakaza neza kutubaza niba hari icyo usabwa kuri coating aluminium coil / urupapuro.
