Niki Kwisukura Mbere Yashushanyije imizingo ya aluminiyumu ？

Kwiyuhagira mbere yo gutwikisha ibishishwa bya aluminiyumu ni ubwoko bushya bwinyubako nibikoresho byinganda byerekana igifuniko kidasanzwe gikoreshwa hejuru yubutaka bwa aluminiyumu, kibaha ubushobozi bwo guhita basukura ikizinga. Binyuze mu miterere ya fotokatalitike cyangwa superhydrophobique yububiko, inshuro zo gukora isuku yintoki ziragabanuka cyane, kuburyo bikwiriye cyane cyane inyubako ndende, ibikoresho byo hanze, nibindi bihe aho kubungabunga bigoye.

Ibisobanuro bya tekiniki na sisitemu yo gutunganya

Substrate na Coating Compression

Guhitamo Substrate:

Ibyiciro bisanzwe: 1100 yuzuye ya aluminium (yoroheje), 3003 aluminium-manganese (irwanya ingese), 5052 aluminium-magnesium alloy (imbaraga-nyinshi). Ubugari bwa coil mubusanzwe buri hagati ya mm 1000 na 1500, hamwe n'ubugari kuva kuri 0.15 kugeza kuri mm 2.0.

Ubuso Mbere yo Kuvura: Chromate cyangwa chromate idafite pasivasi ivura ikoreshwa mugutezimbere ibifuniko (igipimo cya 0-murwego rwo kwipimisha kwambuka).

Amahame ya tekinike n'ubwoko bwo gutwikira

PVDF ating Igifuniko: fluoride polyvinylidene ( PVDF ) gutwikira ni bumwe mu buhanga bwibanze bwo kwisukura ibishishwa bya aluminiyumu. Ubuso bwacyo bworoshye hamwe na UV irwanya ruswa, irwanya ruswa igabanya umukungugu hamwe n’umwanda uhumanya, bigatuma ushobora kwisukura ukoresheje amazi yimvura cyangwa ikirere gisanzwe.

Igikoresho cya Nano-Kwiyuhagira: Ibicuruzwa bimwe bifashisha nano-tekinoroji mu kuzamura hydrophobicite yubutaka hamwe nubushobozi bwo kwangirika kwa fotokatike, bikarushaho kunoza imikorere yo kwisukura.

Ikarita yo kwisukura yikarita yubuhanga:

Ubwoko bw'ikoranabuhanga	Ibigize	Ihame ry'isuku	Ubuzima busanzwe
Ubwoko bwa Photocatalytic (TiO₂)	Dioxyde ya Nano-titanium	Munsi yumucyo UV, ibora ibinyabuzima, kandi amazi yimvura yoza ibisigazwa. Birasaba gukora urumuri (gukora neza ≥90%)	Imyaka 10-15
Ubwoko bwa superhydrophobique	Fluorocarbon resin + nano-silane	Ubuso bw'amazi atemba ahuza inguni> 150 °, ikizinga kigenda gitemba amazi, kandi gishobora no gutandukana kubera uburemere bwumukungugu mubidukikije byumye.	Imyaka 8-12
Ubwoko bwimikorere	TiO₂ + superhydrophobic	Ihuza kwangirika kwa fotokatike hamwe na hydrophobi yo kwisukura, ikwiranye nikirere cyose (ikomeza 60% yo kwisukura ndetse no mubihe byijimye cyangwa imvura)	Imyaka 15–20

Ibyiza byuburyo bwo gutwikira

Gukomeza kuzunguruka: Gukoresha igipfundikizo - gutekesha umurongo uhuza umusaruro (umuvuduko ugera kuri 50-100 m / min), hamwe nikosa ryo guhuzagurika ≤5 μ m, hamwe nubushobozi bwikubye inshuro eshatu ugereranije no gutwikira ibikoresho.

Guhuza nyuma yo gutunganya: Nyuma yo gukira, igifuniko gishobora kwihanganira gutunganywa nko 180 ° kunama no kuzunguruka (urugero, gukora impapuro zometseho imbaho ​​cyangwa imbaho ​​zometseho), kandi imikorere yacyo yo kwisukura ntikibangamiwe no guhindura ibintu.

Ibiranga Ibyingenzi nibyiza bya tekiniki

1. Kwiyuhagira Kwipimisha Ibipimo

Gukuraho Ikirangantego:

Ubwoko bwa Photocatalytic: Kubyuka byamavuta numwuka mwuka wumujyi, igipimo cyo kubora munsi yamasaha 4 yumucyo ni ≥ 95% (bipimishije ukurikije GB / T 23761);

Ubwoko bwa superhydrophobique: Mugihe cyo gukaraba amazi yimvura bigereranijwe, ibisigazwa byibyondo bigabanukaho 80% ugereranije nubusanzwe ( ASTM test D2486 ikizamini).

Kugabanya ibiciro byo gufata neza: Kwambara bisanzwe bisaba koza intoki inshuro 2-33 kumwaka, mugihe ubwikorezi bwo kwisukura bushobora kwagura intera mugihe cyimyaka 3-5, bikavamo kuzigama hejuru ya 60% mumafaranga yo kubungabunga inyubako ndende.

2. Kurwanya Ikirere no Gukingira

Kurwanya UV: Fluorocarubone yo kwisukura yipimishije amasaha 3.000 ya xenon itara ryashaje (itandukaniro ryamabara ΔE ≤ 3), ibereye uturere dushyuha hamwe nizuba ryinshi.

Kurwanya ruswa: Mu bizamini byo gutera umunyu ( ASTM B117), nta ngese ibaho nyuma yamasaha 5.000, ubuzima bwumurimo bukubye kabiri ibyambarwa bisanzwe mubice byinyanja.

Gereranya nimikorere yimyenda isanzwe ya aluminiyumu

Ibipimo	Igikoresho gisanzwe cyabitswe mbere ya aluminium	Kwiyuhagira mbere ya coil ya aluminiyumu (ubwoko bwa Photocatalytic)	Kwiyuhagira mbere ya coil ya aluminiyumu (ubwoko bwa superhydrophobique)
Uburyo bwo Gusukura	Guhanagura intoki / Gukaraba cyane	Kwangirika kwa Photocatalytic + Amazi yimvura	Hydrophobic kuzunguruka + Kumena umukungugu
Amafaranga yo gufata neza buri mwaka	10-15 Amafaranga / ㎡	2-3 Amafaranga / ㎡	3-5 Amafaranga / ㎡
Kurwanya Ikirere	Imyaka 5-10	Imyaka 10-15	Imyaka 8-12
Icyiciro cyo Kurwanya	Icyiciro cya 3 (Ukunda gusiga amanota)	Icyiciro cya 1 (Irwanya gusiga amanota)	Icyiciro cya 1 (Irwanya gusiga amanota)
Ibidukikije bikwiye	Ahantu h'imbere cyangwa handuye cyane	Imirasire y'izuba ryinshi, ahantu handuye cyane ikirere	Ahantu h'imvura, ubushuhe, cyangwa urumuri ruto

Kwiyuhagira mbere yo gutwikisha ibishishwa bya aluminiyumu, binyuze mu guhanga udushya mu ikoranabuhanga ryo gutwikira, byazamuye ibikoresho by’ubwubatsi biva kuri 'passive maintenance' bigera no 'kwisukura.' By'umwihariko mu rwego rwo kuzamuka kw'ibiciro by'umurimo no kurushaho gukenera ibidukikije, babaye igisubizo cyatoranijwe ku mishinga yo hanze. Kuva ku gisenge cy'ikibuga cy'indege kugera ku byapa byo mu mijyi, agaciro kabo ntigashingiye gusa ku kugabanya inshuro zogukora isuku ahubwo no mu kongera igihe cy'ibintu binyuze mu guhangana n'ikirere kirekire, kugera ku 'ishoramari rimwe, amahoro y'igihe kirekire yo mu mutima'. Ku mishinga ishaka gufata neza no kuramba cyane, kwikorera-isuku ya aluminiyumu igenda isimbuza buhoro buhoro ibikoresho byo gutwikira, bihinduka igipimo cyimikorere mubwubatsi bugezweho no gukoresha inganda.
