Kuzunguza amavuta / gusiga amavuta ni ngombwa mugukonjesha gukonje kumpapuro za aluminiyumu, bigabanya kugabanya ubushyamirane, gukora akazi keza no kuzamura ubwiza bwubutaka. Ibisigazwa bya peteroli biguma kuri substrate yambaye ubusa nyuma yo kuzunguruka.

Kubara ibara - ryakozwe na aluminiyumu, substrate inyura mbere yo kuvura (gutesha agaciro, guhinduranya ibintu) ikurikirwa na primer na top - gushushanya hamwe no gukiza ubushyuhe bwinshi.

Niba ibikoresho bya aluminiyumu byinjira bitwara cyane - ibisigazwa byamavuta;

Niba pre - kuvura gutesha agaciro bidahagije;

Niba uburemere - igice cyamavuta yibice bidahindagurika neza mugihe cyo gutwika ifuru;

micro - ingano ya hydrocarbon lubricants irashobora gufatwa hagati ya aluminium substrate na polymer coating layer, itagaragara mumaso.

Icyitonderwa cyingenzi: neza - umusaraba - uhujwe, gutwikira neza bikora nka bariyeri. Amavuta asigaye yafashwe munsi yijwi ntashobora gukoraho ibiryo. Ingaruka zivuka mugihe igifuniko gifite micro - ibice, pinholes, gufatana nabi, kubyimba cyangwa kunanirwa gusaza mugihe cyanyuma - koresha gutunganya cyangwa serivisi.

2. Ibiribwa bishoboka - Ingaruka zo kwanduza ziterwa no kuzunguruka - Ibisigazwa bya peteroli

Ibisigara ntibizahita bitera umwanda; ibyago biterwa nurwego rusigaye, uburinganire bwubushuhe, ubushyuhe bwa serivisi nibiryo media itangazamakuru ryitumanaho (ibinure, aside, ibinyobwa bisindisha). Uburyo nyamukuru bw’ibyago byashyizwe ku rutonde hepfo:

Kwanduza Ibyiyumvo (Byinshi Bidasanzwe Non - Guhuza)

Mugihe cyo gushyushya cyangwa kubikwa igihe kirekire, ibice bihindagurika biva mumavuta yafashwe bishobora kwimuka binyuze muri micro - inenge mubiribwa. Ibi bizana amavuta, yatwitse - amavuta cyangwa impumuro nziza, guhindura uburyohe bwibiryo nimpumuro nziza. Kwanga Sensory bikunze kugaragara muri LFGB nibindi biribwa - guhuza ibizamini byubahirizwa, kabone niyo imiti - kwimuka kwimibare yimibare iri mumipaka.

Ibyimuka byimiti

Amabuye y'agaciro - amavuta - ashingiye kumavuta arimo hydrocarubone ivanze. Iyo inzitizi yo gutwikira yananiwe, imyunyu ngugu - amavuta - hydrocarubone ishobora kwimuka mu binure - matrices y'ibiryo. Ibice byinshi - molekile - uburemere bwibice byamavuta birashobora kandi kugabanuka munsi yubushyuhe bwo hejuru cyangwa gukiza - gukoresha ubushyuhe, bikabyara ihindagurika rishya ryibicuruzwa.

Ubwiza butaziguye - Urunigi rwo kunanirwa

Kuzunguruka cyane - ibisigazwa byamavuta byangiza substrate yubushuhe. Ibi bigabanya guhinduka - gutwikira ubuziranenge no gutwikira performance imikorere ya adhesion. Gupfundikanya ibintu, kubyimba cyangwa micro - pinholes byongeye gufungura imiyoboro yimuka ya substrate - yanduza impande zibiryo - hejuru yabantu.

Kwibutsa bidasanzwe

Iyo ibara - risize aluminium coil ikoreshwa kubitari - ibiryo side impande zombi zihura gusa, kuzunguruka food ibiryo bisigaye byamavuta risk ibyago byumutekano ntibisanzwe. Kugenzura ibisigazwa bikaze ni itegeko gusa kubicuruzwa bitwikiriye - uruhande cyangwa inyuma - byambaye ubusa side uruhande rw'icyuma ruzahuza ibiryo mu buryo butaziguye cyangwa butaziguye.

3. Ibisigisigi byisi - Kugenzura no kubahiriza ibisabwa

Nta kubaho kwisi yose ihuriweho 'kuzunguruka limit amavuta asigara ' kumabara - yashizwemo ibishishwa bya aluminium. Ibisabwa kugenzura biva mubiribwa - kuvugana - amabwiriza yibikoresho, substrate - hejuru - hejuru yisuku hamwe namavuta - ibikoresho - amategeko yo kwemeza.

Amerika FDA Ibisabwa

Munsi ya FDA 21 CFR §178.3910, amavuta azunguruka akoreshwa mu biribwa - guhuza ibyuma bigomba gukoresha FDA - ibice byemewe. Amavuta yose asigaye ku biryo surface guhuza ubutare ntibishobora kurenga 0,015 mg / in⊃2; (≈ 23.2 mg / m²) kubiryo byanyuma - ingingo zandikirwa.

Icyitonderwa cyinganda: iyi ni finale limit ingingo ntarengwa. Aluminium - inganda zikora ibicuruzwa bifata intera ndende yinjira - substrate imipaka kugirango hasigare umutekano muke.

Umuryango w’ubumwe bw’ibihugu by’Uburayi & LFGB

Amabwiriza y’ubumwe bw’ibihugu by’Uburayi 1935/2004 ashyiraho ibiryo rusange - guhuza - inshingano zifatika. Umuryango w'ubumwe bw’ibihugu by’Uburayi 10/2011 ugenga plastike ating gutwikira, byerekana muri rusange - kwimuka - kugabanya OML ≤10 mg / dm². Nubwo idashyizeho umubare wihariye 'kuzunguruka - ibisigazwa byamavuta ' kubutaka bwicyuma, ingingo yarangiye igomba gutsinda ibizamini bya organoleptic (impumuro - uburyohe) no kwimuka - kwerekanwa kubintu bitari nkana - byongeweho (NIAS).

Ubudage LFGB bushira uburemere bwo gusuzuma ibyumviro. Ndetse hasi - urwego rwafashwe ruzunguruka - amavuta ahindagurika arashobora gutera ikizamini cyuzuye. Abahinduzi b’ibihugu by’i Burayi bakunze kwerekana aluminiyumu yinjira isigaye - intego ya peteroli ≤5 mg / m², ibiryo bihendutse - intego y'ibikoresho ≤3 mg / m², bipimwa na infragre - spekitroscopi solvent - uburyo bwo kuvoma.

Igipimo cy’igihugu cy’Ubushinwa

GB 4806.9 kubicyuma - ibiryo - ibikoresho byo guhuza byibanda cyane - ibyuma - kugenzura kwimuka. Mugihe nta gutandukanya kuzenguruka - amavuta - igisigara cyagaciro gisobanuwe, ingingo zirangiye ntizifite umunuko udasanzwe kandi zujuje ibisabwa - kwimuka. Substrate - isuku isabwa ishyirwa mubikorwa binyuze muruganda - inzira - kugenzura ibisobanuro byibiribwa - urwego rwa aluminium shingiro.
