Kuvura Corona kumafirime ya plastike nubuhanga bwibanze bukemura ibibazo bidafatika bya firime - polar. Itezimbere imbaraga zubuso bwa firime binyuze mubikorwa bibiri byumubiri nubumashini, igashyiraho urufatiro rukomeye mubikorwa bizakurikiraho nko gucapa, kumurika, no gutwikira. Inzira yose isaba kugenzura neza gutahura hejuru yubutaka, kuboneza ibikoresho, gushiraho ibipimo, kugenzura ingaruka, no kubungabunga umutekano kugirango ubuvuzi bwiza buhamye kandi bujuje ibyifuzo byinganda.
Incamake yo kuvura Corona
Filime ya plastike ahanini ntabwo - polar polymers. Iyo itavuwe, ubuso bwabo bwo hejuru ni 29 - 33 ingoma / cm, bigatuma bigora wino hamwe nudusimba gushiraho ubumwe bukomeye. Ubuvuzi bwa Corona bukoresha umurongo muremure - wumuriro mwinshi wumuriro wamashanyarazi kugirango uhindure ikirere, bigere kumyuka yumubiri hamwe na chimique polarite ihindurwe hejuru ya firime, byongera cyane uburemere bwubuso bugera kuri 38-52 ingoma / cm, bikemura neza ikibazo cyo gufatira hamwe.
Ihame shingiro ririmo amashanyarazi menshi - yumurongo mwinshi - amashanyarazi atanga amashanyarazi akomeye akora amashanyarazi akomeye hagati ya electrode na roller ya corona, ionizing molekile zo mu kirere muri plasma -. Iyo plasma yibasiye hejuru ya firime, ikora nanoscale 凹凸 inyubako ikoresheje ingaruka za elegitoronike, ikongera ubuso bwihariye, mugihe icyarimwe itangiza amatsinda ya polar nka karubone na hydroxyl binyuze mumyuka ya okiside, byongera ingufu zubutaka. Ubu buryo bubiri butanga firime ivuwe hamwe nubushobozi bwa ankoring hamwe nubushobozi bwa adsorption.
Ugereranije no kuvura ibirimi no kuvura imiti, kuvura corona bitanga ibyiza nkibikorwa byoroshye, ingaruka zishobora kugenzurwa, igiciro gito, kandi nta byuka bihumanya. Irakwiriye cyane cyane kumurongo wo hejuru - yihuta kandi ikaba yarabaye inzira isanzwe munganda nko gupakira ibintu byoroshye, firime za elegitoroniki, no gucapa, bikubiyemo ubwoko bwa firime nyamukuru harimo LDPE, PP, BOPP, na PET.
Gutegura no Kuringaniza Ubuso
Mbere yo kuvurwa, birakenewe kumenya uburemere bwambere bwa firime hamwe nagaciro kagenewe, hanyuma utegure ibikoresho nibikorwa kugirango wirinde kuvura buhumyi biganisha kubisubizo bibi cyangwa kwangirika kwa firime.
Ibisanzwe bya firime hejuru yuburemere nibi bikurikira: Filime ya LDPE isaba kwiyongera kuva kuri 29-31 ingoma / cm kugeza kuri 38-40 ingoma / cm; Filime ya HDPE kuva 30-32 kugeza 39-41 ingoma / cm; Filime ya PP kuva 30-32 kugeza 40-42 ingoma / cm; Filime ya BOPP kuva 31-33 kugeza 40-42 ingoma / cm; PET firime kuva 40-42 kugeza 48-52 ingoma / cm.
Uburyo bwo gutahura hejuru yubutaka burimo uburyo bwo gupima ikaramu ya dyne, nuburyo bworoshye kuri - kumenya urubuga; uburyo busanzwe bwo kuvanga ibizamini ukurikije DIN ISO 8296, nukuri kandi nibyingenzi byo gusuzuma ubuziranenge bwa laboratoire; nuburyo bwa BOPP kaseti uburyo bwo guca urubanza rwambere.
Pre - imyiteguro yo kuvura ikubiyemo igenzura ryumutekano wibikoresho, yemeza ko hashingiwe ku mashanyarazi y’umuriro mwinshi -, nta ruswa cyangwa ibintu by’amahanga kuri electrode, imikorere isanzwe ya sisitemu yohereza imyuka ya ozone, no guhuza inzira ya firime kugirango habeho kugenda neza no gukuna -. Ibipimo byambere bigomba gushyirwaho ukurikije ubwoko bwa firime, ubunini, nubugari.
Ibikoresho Iboneza na Parameter Gushiraho Kuvura Corona
Imikorere yo kuvura corona ishingiye kubikoresho byombi nibikoresho byiza. Ni ngombwa gusobanukirwa imikorere ya buri kintu, gushiraho neza ibipimo byingenzi, no kugenzura no guhindura mugihe nyacyo - kugirango tumenye neza kandi buhamye.
Ibikoresho bigizwe nibice byinshi byingenzi: amashanyarazi menshi - amashanyarazi, sisitemu ya sisitemu, ihindura ingufu za AC hejuru - inshuro nyinshi - isohoka rya voltage; sisitemu ya electrode, irekura ingufu - ingufu z'amashanyarazi; umugozi wo kuvura corona, ukora nka dielectric; sisitemu yohereza imyuka ya ozone, yashyizwe hejuru ya electrode; na sisitemu yo kohereza firime, yemeza ko firime inyura ahakorerwa ubuvuzi kumuvuduko uhoraho.
Ibikorwa byingenzi byingenzi hamwe nuburyo bwo gushyiraho ibitekerezo birimo imbaraga zo kuvura, zibarwa na formula yihariye aho coefficient de power itandukana nubwoko bwa firime; icyuho cya electrode, mubisanzwe 1-3mm; inshuro, inzira nyamukuru 18-30kHz; n'umuvuduko wo kuvura, byahinduwe muguhuza imbaraga.
Ibipimo byerekana amafilime atandukanye nibi bikurikira: kuri firime ya LDPE, coefficient 0.8-1.2, inshuro zisanzwe 18-22kHz; kuri firime ya HDPE, 1.0-1.5, 20-24kHz; kuri firime ya PP, 1.2-1.8, 22-26kHz; kuri firime ya BOPP, 1.5-2.0, 24-28kHz; kuri firime ya PET, 2.0-2.5, 26-30kHz.
Nukuri - kugenzura no guhinduka birimo kugenzura byihuse kumurongo hamwe n'ikaramu ya dyne buri minota 30; kugenzura neza hamwe nibisanzwe byamazi buri masaha 2-4; no guhindura ubwenge ukoresheje sisitemu yo kugenzura kumurongo kugirango igenzurwe neza.
Kugenzura Ingaruka zo Kugenzura hamwe nibitekerezo byakurikiyeho
Kohereza - kwivuza, kugenzura - kugenzura ni ngombwa kugira ngo habeho gukora neza, mu gihe wirinda ingaruka zo kwangirika kw’ingaruka mu gihe cyo gutunganya nyuma kugira ngo ibicuruzwa byanyuma bishoboke.
Uburyo bwo kuvura uburyo bwo kugenzura buva kuri macro kugeza kuri micro: gupima neza uburemere bwikigereranyo ukoresheje uburyo busanzwe bwamazi yikizamini; isesengura ryimiterere yimiti ukoresheje ESCA cyangwa ATR - FTIR; microscopique morphologie kwitegereza ukoresheje SEM; n'ibizamini bifatika byo gukoresha nko gucapa / laminating ibizamini.
Ibyingenzi byingenzi kugirango bitunganyirizwe nyuma harimo kugenzura igihe, nkuko ingaruka zo kuvura zigenda zangirika mugihe, bisaba kurangiza inzira ikurikira mumasaha 24; kurinda umwanda, bisaba ababikora kwambara ifu - uturindantoki na firime kubusa hamwe na firime ya PE mugihe cyo gutwara; ubuvuzi bwa kabiri kuri firime zabitswe kurenza amasaha 48 cyangwa yanduye; no guhuza impagarara, aho inzira zitandukanye zisaba urwego rutandukanye.
Kwirinda no gukemura ingaruka mbi zishobora kugerwaho hifashishijwe uburyo bwiza bwo kuvura, muri - umurongo wa corona, hamwe no gukurikirana iyangirika.
Ibikorwa byo Kurinda Umutekano Ibisobanuro no Kubungabunga
Kuvura Corona birimo voltage nini na ozone, bisaba kubahiriza byimazeyo amategeko yumutekano no gufata neza ibikoresho kugirango igihe kirekire - gikore neza.
Ibikorwa byingenzi byumutekano bikenerwa harimo kurinda ubutaka, hamwe no kumenya buri cyumweru kurwanya ibitaka; kurinda ozone, hamwe na deteri ya ozone yashyizwe mumahugurwa; hejuru - kurinda voltage, bisaba guhagarika amashanyarazi no kwemeza gusohora mbere yo kubungabunga; gukumira umuriro no guturika, kurinda aho bivuriza ibikoresho bitwikwa; no kurinda umuntu ku giti cye, bisaba abashoramari kwambara inkweto zifunguye hamwe nikirahure kirinda.
Ibikoresho byo gufata neza ibikoresho birimo guhanagura buri munsi hejuru ya electrode hamwe na Ethanol ya anhydrous; kugenzura buri cyumweru hejuru ya - umuyoboro wa kabili uhuza no kugerageza sisitemu yo gukonjesha; buri gihembwe cyoza icyuho cya electrode no kugenzura ibyuma bya corona; no gusimbuza buri mwaka insinga nini za - no kumenya umuyaga mwinshi wa ozone.
Incamake n'Ikoranabuhanga
Kuvura Corona kumafirime ya plastike ninzira aho ibisobanuro byerekana intsinzi. Intambwe yose, uhereye kumiterere yubushyuhe bugaragara kugeza kumiterere, kuva kugenzura ingaruka kugeza kubungabunga umutekano, bisaba kugenzura neza kugirango ugere ku ntego z'umusaruro wo gufatira hamwe, gutakaza bike, no gukora neza.
Kugeza ubu, tekinoroji yo kuvura corona iratera imbere igana ubwenge no kuzigama ingufu. Ibikoresho byubwenge birashobora gukoresha AI algorithms yo guhanura ibipimo, kugabanya intoki. Ingufu {2} Kumenya inzira zose zikoranabuhanga bifite akamaro kanini kubucuruzi bwa firime ya plastike kugirango bongere ubwiza bwibicuruzwa no kugabanya ibiciro.
Hefeng, nkumukorikori wabigize umwuga mubushinwa, arashobora gutanga inama nziza ya Plastike ya Corona cyangwa ibikoresho byo kuvura plasma bishingiye kubicapiro byabakiriya (nka firime ya plastike, impapuro, impapuro zicyuma). Ibikoresho byacu bishyigikira ibipimo byahinduwe, hamwe na moderi isanzwe mububiko bwo gutanga vuba. Mbere yo gutanga amasoko, abakiriya barashobora gusaba Ingero zubusa kugirango bapime neza. Dutanga Priceliste isobanutse hamwe na cote, kandi kugura byinshi byujuje ibyangombwa byo kugura kugabanywa, gufasha abakiriya gukemura ibyapa bidahagije ku giciro gito.
