Niki Gitera Gupfundikanya no Gukata Irangi kuri Disiki ya Aluminium?

Disiki ya aluminiyumu isize amabara ikoreshwa cyane mubikoresho byo guteka, ibikoresho byo kumurika hamwe nibikoresho byo gushushanya. Gukuramo ibishishwa hamwe no gukata amarangi byaho ni byo bikunze kugaragara mubibazo byujuje ubuziranenge mu bicuruzwa no nyuma yo kugurisha. Izi nenge zikomoka ku nenge zo mu nda imbere, kubanza kubuvura bidakwiye, gutera imiti no gukiza, ibikoresho byo gutwikira bidahuye, hamwe n’isuri rirerire ry’ibidukikije. Iyi ngingo itondekanya kandi igasobanura impamvu zose zitera munsi yimitwe isobanutse.

1. Inenge Yumurage wa Aluminium Disc Substrates

Ubusanzwe Ubuso bwa Oxidation ya Aluminium

Imiterere karemano yumubiri nubumara bya aluminiyumu nimpamvu zambere zihishe zitera kwifata nabi. Ubwa mbere, aluminiyumu yambaye ubusa ubwayo ikora firime yuzuye, yoroshye ya inert alumina mumasegonda nyuma yo guhura numwuka. Iyi ultra-thin oxide layer ntigira imiterere ya microporome, ibuza guhagarika imashini hagati ya molekile irangi hamwe nicyuma cyuma, bikavamo ahantu hanini cyane nyuma yigihe gito cya serivisi.

Ibisigisigi bisigaye biva mu gutunganya ubukonje

Icya kabiri, disiki ya aluminiyumu yinganda nyinshi igumana amavuta asigara hamwe nubutaka bwa micro nyuma yo gushyirwaho kashe. Amavuta yihishe yafashwe mumikoro aciriritse buhoro buhoro nyuma yo gukira, kumena intera ihuza primer na aluminium.

Imikorere idahwitse ya mashini

Byongeye kandi, ubukana bwa substrate butaringaniye buterwa no guhuza ibipimo bidahuye biganisha ku gipimo cyo kwagura ubushyuhe bwa asimmetrike. Iyo ubushyuhe buhindagurika, disiki ya aluminiyumu ihinduka gato mugihe irangi rikomeye ridashobora kurambura icyarimwe, bikurura inkombe.

2. Ubuso budahagije Mbere yo kuvura mbere yo gutera

Kugabanuka Kutuzuye no Gusukura Ubuso

Ubuvuzi butujuje ubuziranenge bufite hejuru ya 60% yo kunanirwa gukuramo ibicuruzwa byinshi. Mbere yo kuvura byuzuye birimo gutesha agaciro, kurigata alkali, kwoza amazi no kuvura firime. Kugabanuka kutuzuye ni ikosa ryo hejuru rikunze kugaragara: ibintu bigabanya ubukana buke cyangwa igihe kidahagije cyo kunanirwa gukuramo amavuta yo gushushanya, ivumbi hamwe nu icyuya cyamaboko gisigaye muburyo bwo gutondeka intoki. Ibyo bihumanya bigize urwego rwo kwigunga hagati ya substrate na primer, biganisha ku kubyimba no gukonjesha.

Filime yujuje ibyangombwa ya firime

Byongeye kandi, kuvura bidakwiye ni ngombwa. Chromate idahagije cyangwa zirconium igihe cyo guhindura itanga firime ihagarikwa, idashobora kubaka imiti ya covalent ihuza aluminium na primer. Filime ihindagurika cyane nayo itera guhangayika imbere no gusiba.

Umwanda usigaye nyuma yo koza

Hanyuma, amazi asigaye yanduye kumazi atuzuye yogejwe asiga ibibanza byumunyu wa microscopique, bitera kwangirika kwamashanyarazi munsi yumwenda.

3. Gutera nabi hamwe nubushyuhe bwo hejuru bwo gukiza

Imikorere idakwiye

Ibikorwa byo gutera imiti bitujuje ubuziranenge bitera mu buryo butaziguye. Niba intera ya spray intera iri kure cyane, ibice bya irangi atomize bitakaza imbaraga za kinetic mbere yo kwizirika hejuru ya disiki, bigakora irangi rito-adhesion irangi ryoroshye rishobora gucikamo ibice bito. Ubunini bukabije bwa firime buganisha kumutego wimbere; ibisigazwa bisigaye bihindagurika buhoro nyuma yo gukira no kubyara imihangayiko yo kugabana igifuniko.

Gukiza bidasanzwe Ubushyuhe nigihe

Gukiza kudahuza ni ikindi kintu cyingenzi. Kudakiza bisobanura guhuza bituzuye guhuza molekile ya resin, bigatuma igifuniko cyoroshye kandi cyoroshye gukuramo. Gukiza cyane ku bushyuhe bwo hejuru cyane byangiza microstructure ya aluminium kandi bigatera umunaniro ukabije, hagati aho bigatuma firime irangi icika. Ipfunyika zoroshye ntizishobora kunanirwa kugongana cyangwa kugongana mugihe cyo gupakira no gutwara, bikaviramo gukata kuri disiki ya aluminium.

4. Ibikoresho bidahuye hagati yo gusiga irangi no guhuza ibice

Primer idahuye na Aluminium Substrate

Imikorere idahwitse ya sisitemu itera gutinda gukuramo amezi 1-3 nyuma yo kubyara. Ubwa mbere, rusange rusange yibanze ntabwo igenewe aluminiyumu. Bitandukanye na substrate yicyuma, aluminiyumu isaba aside irwanya fosifati yibikorwa bifite imbaraga. Ubusanzwe primers ntishobora kugera kuri molekuline hamwe na firime ya aluminium.

Imikoranire idahuye hagati ya Primer na Topcoat

Icya kabiri, ibara ridahuye hejuru yikoti hamwe na primer biganisha kuri interlayer delamination. Sisitemu zitandukanye (polyester, epoxy, fluorocarbon) zifite igipimo cyo kugabanuka kidahuye mugihe cyo gukira, bigatera impagarara zo hagati.

Imiterere idahwitse ya Topcoat Yarangiye

Icya gatatu, amakoti meza atagaragara neza arimo ifu yuzuza cyane, igabanya guhindagurika. Kuri disiki ya aluminiyumu isaba gukurikira cyangwa gutunganywa gutunganywa, impuzu zidahinduka zizacika kandi zishire kumurongo uhetamye ako kanya.

5. Nyuma yumusaruro wangiritse no kwangiza ibidukikije

Ibyangiritse muburyo bwa Logistique no Gukemura

Kwangirika hanze muri logistique hamwe na serivise yerekana ibintu bitinze kurangi. Guteranya kwa mashini nimpamvu nyamukuru yubukorikori: gutondekanya mu buryo butaziguye disiki ya aluminiyumu idafite impapuro zirinda impapuro zitanga ibimenyetso byerekana ibishushanyo byaguka bikabura. Kugongana kunyeganyega mugihe cyo gutwara inyanja nabyo byangiza impuzu.

Kumara igihe kirekire Hanze Ibidukikije

Kubidukikije, imirasire yigihe kirekire ya UV isenya iminyururu ya molekuline kandi igasaza igifuniko, bikagabanya ubukana bwubutaka. Umunyu mwinshi hamwe nimvura ya acide itera galvanic kwangirika mugutwikira micro-scratches. Ibicuruzwa byangirika byiyongera mubunini no gutondekanya irangi ridahwitse, bikora ahantu hagaragara.

Amagare yo gusiganwa ku magare

Imihindagurikire yubushyuhe bwo hejuru nubushyuhe buke irusheho kongera kunanirwa kwa adhesion bitewe na coefficient yo kwagura ubushyuhe bwa aluminium na irangi.

6. Umwanzuro

Gufata ibishishwa no gukata kuri disiki ya aluminiyumu ni ibintu byinshi byananiranye. Substrate okiside hamwe nibisigara byanduye bitera ingaruka zihishe, mugihe mbere yo kuvura no gukiza byangiza burundu. Kutabangikanya ibintu byihutisha gusibanganya, kandi ibintu byubukanishi nibidukikije bitera inenge zigaragara. Iterambere rigamije harimo uburyo bwuzuye bwuzuye mbere yo kuvurwa, guhuza aluminiyumu yihariye yo gutwikira hamwe nibipimo byiza byo gukiza birashobora gukuraho hejuru ya 90% yinenge nziza.
