Amavuta ya Aluminiyumu yo gupakira ibiryo: Kubahiriza FDA na EU 10/2011

Imirongo yoroheje yo gupakira ibiryo yerekana ibikoresho muburyo bukomeye bwo gupima ubushyuhe, imiti, nubukanishi. Ibahasha yo kubika ibiryo igomba kwihanganira ubukonje bukabije, ubushyuhe bwo hejuru bwa retort sterilisation, hamwe no gukomeza guhura nibiryo bya acide, umunyu, cyangwa ibinure bitarinze kumeneka kumubiri cyangwa imiti.

Guhitamo ibyuma byubatswe neza hamwe na inert organic barrière irangiza ningirakamaro mukuzigama ibicuruzwa bishya no kurinda umutekano wibiribwa. Ibisubizo bya aluminiyumu yumuti byujuje ibyangombwa bisabwa kugirango bikore, bitanga inzitizi zuzuye, ubudahangarwa bw’imiti, hamwe n’uburenganzira bwa FDA bukenewe mu gushyigikira gutunganya ibiribwa ku isi, gupfunyika, hamwe n’imiyoboro ikora ibikoresho.

Igikoresho Cyinshi cyo Gupakira

Ubusugire bwimikorere yibiryo byoroshye cyangwa ibikoresho byishingikiriza kumurongo wibyuma cyane. Niba ifumbire mvaruganda irimo micro-imiterere itandukanye cyangwa inenge zubatswe, imikorere yubuzima bwayo iragabanuka cyane.

Metallurgical Alloy Matrix

Bitandukanye nibyapa byubatswe cyangwa impapuro zubatswe ziremereye, matricike yo gupakira yoroheje ikoresha ubuziranenge-buke, ibinini bya aluminiyumu yoroheje igizwe neza kugirango irambure kandi irinde inzitizi imwe.

• 8011 Amavuta (urugero, 8011): Ibipimo ngenderwaho mpuzamahanga kubiribwa byo mu rwego rwo hejuru byoroshye kandi byubaka. Kwiyongera kubintu bya tronc nka fer na silicon bitanga matrike itunganijwe yerekana ibintu byiza cyane, birwanya gucumita, hamwe nubucucike buke bwa pinhole kuri ultra-thin gauges.

• Ubushyuhe bwa Mechanical (O / H18 / H22): Ubushuhe bworoshye bwuzuye (O-ubushyuhe) butanga ibintu byinshi byapfuye kandi bigahungabana cyane kubintu byashushanyije byimbitse hamwe nibishobora gukoreshwa, mugihe igice cyinshi gitanga imbaraga zubaka kurukuta rukomeye.

Ibiribwa byinshi-birinda umutekano Lacquer Ubwubatsi

Gutandukanya burundu insimburangingo ya aluminiyumu ibice byibiryo bya acide cyangwa alkaline mugihe ufunze ogisijeni nubushuhe, imirongo igezweho yimashini ikomeza ya roller-coating ikoresha ultra-thin, sisitemu yo gukingira:

Kugereranya Umutwe-Kuri-Kugereranya: Ibipapuro bisanzwe bipfunyika hamwe na Lacquered Foil

Iyi tekinoroji yubuhanga igereranya yerekana itandukaniro ryimiterere hagati yimpapuro zipfunyitse zambaye ubusa cyangwa zidahagije hamwe nimpapuro zemewe zo mu rwego rwo hejuru:

Ibyingenzi Byibanze Mubiribwa Byinshi-Ibiribwa na Sterile

Imikorere yimikorere ya lacquer yamashanyarazi yemewe itezimbere kubidukikije byihariye nibisabwa kubiribwa bitandukanye mubyiciro byubuzima:

Ibibazo

Q1 :: Nigute feza ya aluminiyumu igera kuri FDA yemewe kubahiriza ibiryo bitaziguye?

Igisubizo : FDA yubahiriza bisaba urwego rwa lacquer organique gutegurwa gusa bivuye mubikoresho fatizo biri munsi ya 21 CFR § 175.300. Filime yakize igomba gutsinda ibizamini bikururwa byimuka ikoresheje simulator yibiryo kugirango igenzure ko nta bintu byangiza byinjira mubiribwa.

Q2: Ni izihe ngaruka zo gukoresha ifu ya aluminiyumu itujuje ubuziranenge cyangwa yambaye ubusa hamwe n'ibicuruzwa birimo aside irike cyane?

Igisubizo: Bare aluminiyumu irashobora gushonga mugihe ihuye nibiryo bifite pH iri munsi ya 4.Iyi reaction itera kwangirika bishobora kwangiza ibahasha yipakira, kubyara gaze ya hydrogène, no guhungabanya umutekano wibiribwa winjiza ioni yicyuma kirenze mubicuruzwa.

Q3: Ipitingi ya lakeri irashobora kwihanganira gufunga inshuro nyinshi cyangwa gufunga ubushyuhe butaziguye?

Igisubizo: Yego. Dingang ikoresha thermoplastique cyangwa yahinduwe ya cololymer ubushyuhe-kashe ya lacquers. Iyi myenda yakozwe kugirango igumane ituze mugihe cyo kubika ariko gushonga no guhuza neza na substrate ya plastike (nka PP, PS, cyangwa PE) muburyo bwo gufunga ubushyuhe.

Q4: Niki 'kubika amavuta, ' niki kandi Dingang yabikuraho gute mugihe cyo gukora?

. Igisubizo Dingang Metal ikuraho burundu inenge muguhindura ibikoresho byose binyuze murwego rwo hejuru rwimashini . Izi sisitemu ziringaniza imihangayiko yimbere kurubuga rwose rwicyuma kugirango hamenyekane neza neza ( <0.5 mm / m gutandukana), birinda ibintu byangiritse cyangwa imiraba igaragara kumashanyarazi yihuta yihuta kandi ikora cassette.

Igisubizo: Yego, ibyiciro 2026 byose byakozwe byemewe PFAS-yubusa. Umurongo wose utwikiriye ukoresha sisitemu yo mumazi igezweho, idafite fluor ya polymer yujuje imipaka igezweho yubuzima bushingiye ku bidukikije mugihe ikomeza gukora inzitizi nziza.

Q6: Lacquer ya BPA-NI ni iki, kandi ni ukubera iki ihitamo kubisabwa bigezweho?

Igisubizo: BPA-NI bisobanura Bisphenol-A Atari Intego, bivuze ko BPA idakoreshwa nkibintu nkana mubushake. Iyi myenda ikundwa kwisi yose kugirango yubahirize ingamba zigezweho zo kwihaza mu biribwa by’iburayi n’Amerika y'Amajyaruguru bibuza BPA mu gupakira ibiryo bitaziguye.

Umwanzuro

Gushakisha ibikoresho byo gupakira ibiryo byinshi cyane bisaba guhuza amavuta hamwe nibikorwa bya lacquer. Mugihe impapuro zisanzwe zikwiranye nibintu byoroshye byumye, byemewe lacquer ya aluminiyumu yifashishije ingirakamaro ya 8011/1000 yuruhererekane rwinshi hamwe na lacquer irinda imipaka itanga imiti irwanya imiti hamwe nigihe kirekire cyumuriro gikenewe mugusaba retort hamwe nibiryo bya acide. Gufatanya na producer uhuriweho nka Changzhou Dingang Metal Material Co., Ltd. yemeza ko umushinga wawe ushyigikiwe nubwiza bwibintu byagenzuwe no kubahiriza kuva master roll kugeza kurangiza.
