Scratch-Resistant PU / PA imizingo ya aluminiyumu kuri sisitemu yo mu bwoko bwa Sun Shading Sisitemu

Inyubako yo kugenzura izuba hanze - cyane cyane moteri yimpumyi ziva hanze (EVB) hamwe na sisitemu yo gutwika izuba yo mu bwoko bwa Venetiya - ikora munsi yubushyamirane bukabije hamwe nizuba rihoraho. Bitandukanye no gukuta urukuta ruhagaze, abakunzi ba aluminiyumu hamwe nibice bigenda bihindagurika bikomeza guhindagurika, kuzunguruka buri munsi, hamwe no guhindagurika k'umuyaga.

Kugira ngo wirinde inkovu zitaragera, kwambara ku nkombe, no kwangirika kw'irangi, abakora ibicucu ku isi baragenda bava mu myenda gakondo bajya kuri Polyurethane-Polyamide (PU / PA) ibishishwa bya aluminiyumu..

Hano haribisobanuro byubuhanga byerekana impamvu PU / PA coil coating chemistry itanga uburyo butagereranywa bwo guhangana, guhuza imiterere, no kuramba kubwoko bwa sunset yo mu bwoko bwa Venetiya.

Ikibazo cya Tekinike: Kwambara Dynamics Yimpumyi Zinyuma

Sisitemu yo mu bwoko bwa Veneziyani itanga izuba ryihariye risaba ibyuma byabugenewe:

1. udupande tw’akayagaIntera

2. Micro-Particle Abrasion : Umukungugu, umucanga, nuduce twumuyaga dukora nkibintu byangiza mugihe cyizuba rya buri munsi, bigenda bigabanuka buhoro buhoro.

3. Kwunama gukabije : Ibice bya kijyambere bya Venetiya biranga Hemmed Edges (nka C, ishusho ya Z, cyangwa S ishusho ya S) byakozwe kugirango byongere ubukana n’umuyaga. Ipfunyika ntoya micro-crack kuri radiyo ifunganye.

Ipitingi ya PU / PA ikemura ibyo bibazo muguhuza umugongo ukomeye wa Polyurethane hamwe na micro-amasaro ya polyamide..

Nigute PU / PA Coating Chemistry Irinda Ibice bya Venetiya

 irangi risoza : PU Matrix + Polyamide (PA) Ibice < AW-3005 / 3105/3004 H46 / H48) <- Imbaraga Zitanga Umusaruro & 平整度 umvange wa aluminiyumu Yinyuma (Epoxy / PE 

1. Kugabanya Polyamide Ibice Kugabanya Kugabanuka

Kwishyira hamwe kwa micronized polyamide sisitemu ikora microscopique yimiterere hejuru. Iyi mikoro yo kwisiga-mikoro igabanya cyane coefficente yo guterana iyo ibice byanyuze hejuru cyangwa kuruhande rwa gari ya moshi, bikagera ku gipimo cyo kurwanya ≥ 20 N.

2.

Gukora C-shusho ya Z cyangwa Z-hanze yinyuma ya Venetiya bisaba kuzunguruka neza hamwe na radiyo ifatanye. Ipitingi ya PU / PA itanga ubuhanga budasanzwe, igera ku gipimo cya 0T kugeza kuri 1T itagabanije micro-yamenetse cyangwa gutakaza gufatira hamwe ( ASTM D3359). Ibi birinda kwinjiza ubuhehere no kwangirika kumunwa wakozwe.

3. UV Guhagarara & Kugumana Ibara

Sisitemu yo kugicucu yo hanze itwara imirasire y'izuba. Yakozwe hamwe na polyurethane iramba cyane hamwe na pigment ya organic organique, impuzu za PU / PA zigumana amabara akomeye (ΔE <0.5) kandi ikarwanya kunyerera mugihe kirekire cya UV.

Kugereranya tekinike: Substrates ya sisitemu yo hanze ya Venetiya

Substrate Metallurgie: Guhitamo Amavuta meza na imiterere y’umvange

Kugirango ugumane uburinganire bwuzuye hejuru yidirishya ryagutse utagabanije, guhuza impuzu za PU / PA hamwe na metallurgie ya aluminiyumu ni ngombwa:

Guhitamo Amavuta : EN AW-3005, 3105, cyangwa 3004 (Urukurikirane rwa Al-Mn-Mg kugirango rutange umusaruro mwinshi hamwe no kurwanya ruswa yo mu kirere).

imiterere y’umvange​ ​ ​

ubugari bw’igipfundikizo : irangi risoza 20-25 µm (Ubunini bwa Filime Yumye: 25-28 µm).

Icyerekezo cy'ubugari : 0,20 mm kugeza kuri 0,45 mm (Ubugari bwihariye bwagabanutse kugera kuri ± 0,05 mm).

Uzamure Igicuruzwa cyawe Igicucu

Kugaragaza ibishishwa bya aluminiyumu ya PU / PA ya sisitemu yo kugenzura imirasire y'izuba yo mu bwoko bwa Veneziyani itanga igihe kirekire ikora neza, irangi rya zeru mu gihe cyo gukora ibizunguruka, hamwe no kuramba hejuru kurwego rwo hejuru rwubucuruzi n’imiturire myinshi.

Saba Impapuro za Tekiniki Impapuro & Icyitegererezo

Ukeneye ibishishwa bya PU / PA byuzuye bya aluminiyumu bihuye na geometrike yawe ya shitingi? Menyesha itsinda ryacu ryo kugurisha ibicuruzwa bya tekinike uyu munsi kugirango wakire impapuro za tekiniki, amakarita ya swatch, hamwe nicyitegererezo cyo kwemeza umusaruro wawe.
