Niki gitera gucika irangi mugihe cyo kunama? Kwirinda Kunanirwa kwa Aluminiyumu

Mu mpapuro zikozwe mu cyuma, ibishushanyo mbonera bya aluminiyumu mbere yo gusiga irangi, bikozwe mu muzingo, kandi bigashyirwaho kashe kugira ngo bitange igisenge gihagaze, imiyoboro y'imvura, imyambaro ya cassette, hamwe n'ubwubatsi. Ariko, abahimbyi bakunze guhura nikibazo cyingenzi: gusiga irangi mbere ya irangi ya aluminiyumu mugihe cyo kunama .

Iyo ibyuma byabanje gusiga irangi bigenda byunama bikabije, firime yo gusiga irangi kumaradiyo yo hanze ihura nibibazo byinshi. Niba uku kurambura kurenze kwifata, microscopique yamenetse (micro-crazing) ikora kumurongo uhetamye. Igihe kirenze, utwo dukoko duto duto twerekana ibyuma biri munsi yubushyuhe, imyunyu yo mu kirere, hamwe n’imyanda ihumanya inganda, biganisha ku gutwika ibishishwa, kwangirika, no kunanirwa mu murima imburagihe.

Gusobanukirwa impamvu gusiga amarangi no gushyira mubikorwa ibikoresho bikwiye, guhitamo ibivanze, hamwe nibisobanuro bifatika bituma abahimbyi bagera kumaradiyo yunamye batabangamiye irangi cyangwa ubwiza.

Fiziki ya Micro-Cracking mugihe cyo gukora impapuro

Mugihe cyo gukora feri yo gukanda cyangwa gukora umuzingo uhoraho, insimburangingo yicyuma hamwe nubutaka bwamabara kama bigira imbaraga zitandukanye.

Hanze Ubuso bwa Tensile Strain & Filime yo Kurenza Imipaka

Iyo urupapuro rwa aluminiyumu yubunini  t  yunamye kuri radiyo r , ubuso bwimbere bugabanuka mugihe ubuso bwinyuma bugira uburebure bukabije . Filime yo gusiga irangi irambuye ugereranije nintera yayo kuva hagati itabogamye. Niba irangi ryirangi ridashobora kurambura nkicyuma kiri munsi, firime irangi iraturika.

Micro-Cracking Dynamics: Crazing, Delamination, na Flaking

• Micro-Crazing: Ibice byimisatsi ya Microscopique bigaragara kumyenda yo hejuru munsi yumuvuduko mwinshi, akenshi bisa nkugutakaza gloss cyangwa umurongo wa chalky kumurongo uhetamye.

• Macro-Cracking: Imvune zimbitse, zigaragara zicamo ikoti hejuru na primer kugeza hasi ya aluminiyumu mbisi yabanje gutunganywa.

• Delamination & Flaking: Bibaho mugihe kumena amarangi biherekejwe no gufata neza primer, bigatuma ibara risiga irangi kure ya substrate mugihe cyo gukora.

Imiterere & Binging Limits Matrix: Coatings na Alloy Tempers

Porogaramu Ifatika Ifatika: Gukora Uruzitiro Rwinshi

Guhitamo ibishishwa bikwiye, sisitemu yo gutwikira, hamwe nubuhanga bwo gukora birinda gusiga amarangi mu nganda zingenzi zikora ibyuma:

Ibibazo

Q1: Niyihe mpamvu nyamukuru itera kumena irangi mugihe uhetamye aluminiyumu yabanje gusiga irangi?

Igisubizo: Impamvu nyamukuru nukunama urupapuro rwarenze urugero rwa firime ntarengwa. Ibi mubisanzwe bibaho mugihe ukoresheje radiyo igoramye ifunze cyane ( 0T ), ukoresheje sisitemu yo gukiza birenze cyangwa ivunaguye, kugoreka ibyuma bikonje, cyangwa guhitamo ubushyuhe bukabije bwibanda kumurongo kumurongo muto.

Q2: Nigute ubushyuhe bwibicuruzwa bidukikije bigira ingaruka kumikorere ya aluminiyumu yabanje gushushanya?

Igisubizo: Ubushyuhe bukonje ( <15 ° C / 59 ° F ) butera irangi ryirangi gukomera, bigatuma rivunika mugihe cyo gukora. Gushyushya ibikoresho kugeza kuri 20 ° C - 25 ° C  bigarura imiterere ihindagurika, bifasha kwirinda gucika mikorobe mugihe cyunamye.

Q3: Ni irihe tandukaniro riri hagati ya 0T yunamye na 2T igoramye?

Igisubizo: A 0T  yunamye bivuze ko ikibaho gishobora kuzinga 180 ° hejuru yacyo ubwacyo nta gusiga irangi cyangwa gufata kaseti. kwa 2T  Kwunama bisaba icyuho kingana n'ubugari bubiri bw'icyuma ( 2t ) imbere ya radiyo yunamye kugirango wirinde kunanirwa.

Q4: Ese kote 3, 35-micron yubaka sisitemu yo gusiga irangi igera kuri 0T?

Igisubizo: Amashusho yerekana irangi ( 35 μ m ) afite uburambe bwo hejuru hejuru mugihe cyo kugunama gukabije. Mugihe sisitemu isanzwe 2-ikoti ( 25 mkm ) igera kuri byoroshye 0T , sisitemu yubaka-3-ikoti isanzwe isaba 1T - 2T  radiyo ya kugirango irinde gucamo mikorobe hejuru.

Q5: Ni ubuhe buryo bwo gusiga amarangi bwiza kuruta imyanda yimvura hamwe nigisenge gihagaze cyizengurutswe?

Umwanzuro

Kwirinda kumeneka amarangi mugihe cyo kugonda aluminiyumu bisaba guhuza chimie iburyo bwa resin, ubushyuhe bukabije, urupapuro rwerekana, hamwe na radiyo. Mugusobanura uburyo bworoshye bwo gutwika PVDF cyangwa HDP hamwe na yemewe 0T - 1T  T-bend , abayihimbye barashobora gutanga imyirondoro ityaye, iramba itarinze guterwa no guturika hejuru cyangwa gusiga irangi ryigihe kirekire.
