Ni irihe tandukaniro riri hagati yuburabyo hagati ya matte, gloss-gloss hamwe nicyuma gisukuye ibara ryometse kuri aluminiyumu？

Ibisobanuro

Ibara ryometse kuri aluminiyumu ni ibikoresho byoroheje byo gushushanya bikoreshwa cyane mu rukuta rwububiko bwububiko, sisitemu yo hejuru mu nzu, imbere yimodoka imbere hamwe nibikoresho byo murugo. Ububengerane, busobanurwa nkubushobozi bwubuso bwo kwerekana ibyabaye bidasanzwe urumuri, nicyo kintu cyihariye cyo gutandukanya ibintu bitatu byingenzi bivura hejuru: matte, gloss-gloss hamwe nicyuma gisukuye. Iyi ngingo igereranya ibipimo byuzuye byerekana ububengerane, uburyo bwo kwerekana urumuri, uburyo bwo gutwikira ibintu hamwe n’ibikomoka ku mikorere ishingiye ku gipimo cya 60 ° cyo gupima glosse yemejwe n’inganda zitunganya aluminiyumu, ikanasesengura ibintu byakoreshejwe kuri buri kurangiza.

1. Inganda zipima Inganda Ibipimo Byibara rya Aluminiyumu

Amakuru yose yuzuye muri iyi mpapuro akurikiza ibipimo bya ISO 2813, ikoresha urumuri rwa 60 ° rw'urumuri kugira ngo hamenyekane buri gihe ibyuma bisize ibyuma, impande zose zipimisha ku bakora inganda za aluminium. Ibice byerekana ububengerane bigaragazwa nkibice bya gloss (GU), aho 100 GU igereranya indorerwamo isanzwe hamwe nibisobanuro byuzuye. Bitandukanye n'ibikoresho bikozwe muri pulasitiki, imirongo ya aluminiyumu isize ibara igumana igice cya substrate metallic igaragaramo na nyuma yo gutwikisha ibinyabuzima, biganisha ku mategeko yihariye yo guhindagurika kw'ibara ritandukanye n'ibikoresho bitari ibyuma. Ibice bitatu birangiza byagenwe byuzuye glossing yagenzuwe ninganda zikora aluminiyumu:

• Ibara ryibara ryometse kuri aluminiyumu: 5-40 GU

• Ibara ryinshi-ryuzuyeho ibara rya aluminiyumu: 80-95 GU

• Ibara ry'icyuma ryogejwe ryometseho imirongo ya aluminium: 35-60 GU

2. Ibiranga uburabyo hamwe nuburyo bwiza bwo gutekereza

2.1 Ibara rya Matte Yometseho Aluminiyumu: Kugaragaza Diffuse na Gloss idasanzwe

Imyenda ya aluminiyumu ifata materi polyester (PE) cyangwa fluoride ya polyvinylidene (PVDF) ikingira hamwe na microscopique silika itandukanijwe neza imbere ya firime irangi. Ubuso bwa microscopique bwerekana ihindagurika ridasanzwe rya convex-convex iri munsi ya microne 10. Iyo urumuri rugaragara rumurikira hejuru, hejuru ya 90% yumucyo wibyabaye bigenda bikwirakwizwa aho gutekereza cyane. Mubigaragara, ubuso bwerekana ibintu byoroshye, igihu kitari cyiza na zeru zeru. Mu ntera ya 5-40 GU, imirongo ya matte yo hasi (5-20 GU) ikuraho ibimenyetso byose byerekana ibyuma byerekana, mugihe imirongo yo hagati ya matte (20-40 GU) igumana intege nke zishingiye kumyuma ya aluminium. Kurangiza ntibishobora kubyara indorerwamo isobanutse yibintu bikikije ibihe byose.

Amabuye maremare ya aluminiyumu akoresha amakariso adafite umusemburo wo hejuru utagaragara neza utarinze guhuza inyongeramusaruro, uhujwe ninshuro eshatu zipfundikirwa hamwe nubushyuhe bwo hejuru bukiza. Irangi rya firime irangi igenzurwa munsi ya microne 0.8, igera hafi yindorerwamo. Kurenga 85% byumucyo wibyabaye bitanga ibitekerezo byihariye kumurongo ugaragara. Hamwe nuburabyo hejuru ya 80 GU, hejuru irashobora gukora indorerwamo itagaragara yerekana inyubako, amatara nabakozi. Munsi yizuba ryizuba, kwibanda kumurongo bitanga urumuri rugaragara, bitera umunaniro ukabije. Hagati aho, uburebure buringaniye bwongerera utuntu duto duto nko gushushanya hamwe nuduce twumukungugu, bigatuma ubusembwa bugaragara cyane kuruta matte.

2.3 Amabuye asukuye Ibara ryometseho Aluminiyumu: Icyerekezo kivanze

Ibyuma bya aluminiyumu yajanjaguwe biratandukanye cyane nubundi bwoko bubiri bitewe nubushakashatsi bwakorewe mbere. Ababikora bakoresha ibyuma byuma bidafite umuyonga kugirango bahanagure insimburangingo ya aluminiyumu kugirango bakore umurongo uhoraho ugereranije na micro-grooves ifite intera ya mm 0.1-0.3 mbere yo gutwikira. Ububengerane bwacyo nibyerekezo bivanze byerekanwe: urumuri ruringaniye numurongo wahanaguwe rutanga imbaraga zidasanzwe zo gutekereza, mugihe urumuri rutandukanijwe kumirongo isukuye rutanga ibitekerezo byo gukwirakwiza. Muri rusange urumuri rwuzuye rugwa hagati ya matte na gloss-hejuru kuri 35-60 GU. Mu buryo bugaragara, ifite urumuri rutaringaniye: ubuso bugaragaza urumuri rwiza cyane iyo urebye icyerekezo cyo guswera, hamwe nijwi ryijimye ryijimye iyo urebye neza. Bitandukanye na matte yuzuye irangiza, igumana imiterere itandukanye yicyuma aho kuba igihu kiboneye.

3. Gutunganya Impamvu Zitera Ubunini

3.1 Kurangiza Matte: Guhuza Ibice Kuvanga no Gukiza-Urwego rwo hasi

Moss gloss ihindurwa nigipimo cyifu ya organic organique muri topcoat. Ifu yo hejuru ya porojeri igabanya imikorere iringaniza mugihe cyo gukira, ikora microscopique yubatswe. Imyenda ya PVDF ifite gloss igumya kurenza PE; gloss attenuation iri munsi ya 3 GU nyuma yimyaka 20 yo hanze, ikwiriye gukoreshwa igihe kirekire.

3.2 Kurangiza-Gloss Kurangiza: Gufata neza Roller hamwe no gukiza umukungugu

Umucyo mwinshi ushingiye kumahugurwa adafite ivumbi hamwe nisuku iri hejuru yicyiciro 10,000. Umukungugu muto uzatera kugabanuka kwimbere. Nyuma yambere yibanze yambere hamwe no gutwikisha amabara, ikoti iringaniye ikoreshwa hejuru inshuro ebyiri kugirango yuzuze substrate micro-pits. Ubushyuhe bwo gukiza bwiyongereyeho 15 ℃ ugereranije nibicuruzwa bya matte kugirango byihutishe umuvuduko wa firime kandi bikureho impanuka.

3.3 Kurandura Ibyuma Kurangiza: Substrate Texturing ikurikirwa na Transparent Thin Coating

Gloss yamenetse yiganjemo imiterere ya substrate aho gusiga irangi. Ikoti yo hejuru ikoreshwa ni ultra-thin yoroheje irangi ryicyuma gifite uburebure bwa 5-8 mm gusa, bitazaba bitwikiriye imirongo yasunitswe. Gupfundikanya cyane bizuzuza micro-grooves kandi bikureho itandukaniro ryurumuri rwerekezo. Nyuma yo gukaraba passivation ivura irasabwa kwirinda okiside yaho iganisha kumurabyo udahuye.

4. Imikorere nogukoresha Itandukaniro Bituruka Kumurabyo

5. Umwanzuro

Itandukaniro ryibanze ryibara ryibara ryibara rya aluminiyumu itatu rituruka kuri microscopique morphologie hamwe nuburyo bwo kwerekana urumuri. Ibicuruzwa byinshi-gloss biranga ibintu byihariye byerekana kandi byerekana indorerwamo hamwe na 80-95 GU; ibicuruzwa bya matte biranga gukwirakwiza kwuzuye no kwerekana igihu gike-gloss hamwe na 5-40 GU; ibikoresho byogejwe byicyuma biranga icyerekezo kivanze nicyerekezo giciriritse kuri 35-60 GU. Muguhitamo gufatika, ibisabwa kugirango urumuri rugenzure rugena imikoreshereze ya matte, urwego rwohejuru rwiza rwo gushushanya rusobanura imikoreshereze-yuzuye-gloss, hamwe nicyuma cyubwiza bwubwiza busaba ikoreshwa ryicyuma. Ababikora bagomba guhuza uburyo bwo gutwikira hamwe nuburyo bwo kwitegura hakurikijwe amatara hamwe nibisabwa kugirango babungabunge ububengerane.
