Impamvu PU / PA Yashizweho imizingo ya aluminiyumu ni Zahabu Zahabu kuri idirishya rifunga rizunguruka Sisitemu

Mugihe uhitamo ibyuma byabugenewe byabugenewe kugirango izuba ryimbere ryizuba hamwe nububiko bwububiko bwa roller, amatsinda yamasoko nababikora bahura nibibazo byinshi byubuhanga. Ibikoresho byubatswe byubatswe bigomba kwihanganira imishwarara ya UV, ihindagurika ryubushyuhe bwibidukikije bwihuse, kugabanuka kwimyuka yo mu kirere, hamwe no guhora mukibazo cya mashini mugihe cyo gukora no gukora buri munsi.

Mugihe ibipimo bisanzwe bya Polyester ( PE ) na Polyvinylidene Fluoride ( PVDF ) bitwikiriye bikenera imyubakire yagutse, Polyurethane-Polyamide (PU / PA) ikozwe muri aluminiyumu yerekana ko ari zahabu yihariye ya sisitemu yo hanze ikora neza.

Hano haribintu byubwubatsi byerekana impamvu PU / PA coil coating chemistry itanga impagarike nziza yo kurwanya ibishushanyo, guhinduranya ibintu, no guhindagurika kwigihe kirekire.

Ubuhanga bwa Chimie Inyuma ya PU / PA: Yashizwe Kumurongo no Guhangayika

Imikorere isumba iyindi ya PU / PA ikomoka kuri materix ya polymer ihuza ikomatanya resin ya polyurethane hamwe na polyamide ihuza ibice:

Matrix ya Polyurethane (PU) : Itanga ubunyangamugayo bwubatswe, guhuza molekile yuzuye, no kurwanya cyane imiti n’imishwarara ya UV. Umuyoboro wa polyurethane ukora umugongo utoroshye, woroshye urwanya gucika munsi yimikorere iremereye.

Guhindura Polyamide (PA) Guhindura Ibice : Ibice bya polyamide bikwirakwijwe neza muri kote yose. Mugihe cyo gukira, utwo dusaro duto dukora ubuso bugabanya cyane coefficente yo guterana.

 irangi risoza PE umvange wa aluminiyumu 

Muri porogaramu yo gufunga porogaramu, imyirondoro ya slat ikomeza kunyerera hagati yizunguruka no kuzunguruka. Ikoti risanzwe ryoroshye akenshi rirwara gukuramo no gutwika hejuru mugihe. Imyitwarire yo kwisiga ya micro-polyamide yongeraho ikuraho ubushyamirane hagati, ikomeza ubuso bwuzuye hejuru yibihumbi.

 Ibyiza bya Tekiniki Byiza Kubakora Shutter

1. Igishushanyo kidasanzwe & Mar Kurwanya (Gukomera Scratch ≥ 20N)

Mugihe cyo gutondekanya umwirondoro, guhoraho-kuzunguruka, no kwihuta kwihuta guterana, hejuru ya coil irangi irangi ihura nicyuma-cyuma. Ipitingi ya PU / PA igera ku ikaramu ikaramu ya 2H - 3H mugihe ikomeje guterana hejuru. Ibi birinda amanota yo hejuru no kwangirika mugihe cyo gukora no mumirima.

2. Ihinduka ryinshi rya T-Bend idafite Micro-Cracking

Gukora aluminiyumu yamashanyarazi bisaba radiyo igufi kandi igororotse neza.

Ipitingi isanzwe irashobora guteza imbere kuvunika mikorobe ku murongo uhetamye, bikagaragaza insimburangingo ya aluminiyumu mbisi kandi igahita yihuta.

Sisitemu ya PU / PA igera ku gipimo cya 0T kugeza kuri 1T itagabanije cyangwa ngo itakaze ifata rya kaseti ( ASTM D3359), byemeza ko inzitizi yo gukingira ikomeza kuba ntamakemwa ku mpande zikarishye.

3. Isumbabyose ya Polyurethane Ifuro

Amashanyarazi yimashini yishingikiriza kuri polyurethane yatewe inshinge (PUR / PIR) ifuro ya furo yo kubika ubushyuhe no kugabanya amajwi. Ikoti yo gukingira ikingira ingofero ya PU / PA yateguwe kugirango ihuze imiti na sisitemu ya polyurethane. Ibi birinda gusibanganya hagati ya aluminiyumu nigikoresho cyo kubika mugihe cyamagare yubushyuhe.

4. UV Ihamye & Kurwanya Kurwanya

Byakozwe hamwe na polyurethane yo mu rwego rwohejuru hamwe na pigment iramba idasanzwe, sisitemu ya PU / PA yerekana amabara meza cyane (Δ E <0.5batch idahwitse) hamwe no kugenzura ububengerane bwizuba ryinshi. Yageragejwe kwihanganira amasaha arenga 1.000 yumunyu utabogamye (NSS) ukurikije ISO 9227, aluminiyumu ya PU / PA irwanya neza imyanda no kwangirika kwangiza ibidukikije ku nkombe n’inganda.

Ibisobanuro bya tekiniki Kugereranya: PU / PA na PE v. PVDF

Basabwe Alloy & Mechanical Parameter

Kugirango ugere kubintu byiza kandi birwanya imitwaro muburyo bwo gufunga, guhuza ibishishwa byiza hamwe nubushyuhe hamwe na PU / PA ni ngombwa:

Ibishushanyo mbonera : EN AW-3005, 3105, cyangwa 3004 (Urukurikirane rwa Al-Mn-Mg kugirango imbaraga zongerewe umusaruro no kurwanya ruswa).

imiterere y’umvange Imiterere : / H48 H46

ihanganiriro ry’ubugari​

Gukora neza no gutanga ibyiringiro

Guhitamo iburyo bwa PU / PA bikozwe muri aluminiyumu ituma ibikorwa bikora bidafite aho bihuriye, ibiciro byo hasi mugihe cyo gushushanya, hamwe nabakiriya ba zeru bavuga kubijyanye no gukuramo hejuru cyangwa gusiga irangi.

Waba urimo gukora idirishya ryoroshye ryo guturamo cyangwa inzugi zumutekano zubucuruzi ndende, gutunganya ibicuruzwa neza - harimo ubugari bwagutse, guhuza ibara munsi yurugero rukomeye ΔE, hamwe na firime ikingira - byemeza ubuziranenge buhoraho kuva kuri coil kugeza kubicuruzwa byarangiye.

Saba Tekinike Ibisobanuro & Ibikoresho by'icyitegererezo

Urebye kugirango uhindure umurongo wawe wo gufunga umurongo hamwe na PU / PA ikora cyane ya coil ya aluminium? Menyesha itsinda ryacu ryubuhanga bwo kohereza ibicuruzwa hanze uyu munsi kugirango ubone ibisobanuro birambuye bya TDS, imbonerahamwe y'amabara, hamwe na coil y'icyitegererezo ijyanye na geometrie yawe.
