Ikibazo cya Adhesion mugupakira kijyambere
Mu bice byo gutwika no gutwika, kugera ku gukomera gukomeye, kwizerwa hagati ya firime ya polymer nizindi nzego (nk'impapuro, impapuro, cyangwa ibice bya pulasitike) ni ikibazo cyibanze ariko gikomeje. Polimeri nka polyethylene (PE) na polypropilene (PP) iba idafite imiti kandi idakoreshwa, ifite ingufu nkeya, bigatuma irwanya ubwuzuzanye hamwe na wino, ibifuniko, hamwe nibifatika. Ibi biranga bigira ingaruka ku buryo butaziguye ubuziranenge, kuramba, n'imikorere y'ibicuruzwa byanyuma, uhereye ku gupakira ibiryo byoroshye kugeza kuri pouches. Kugira ngo dutsinde iyi nzitizi, inganda zafashe imiti myinshi ya corona isohoka nkigikorwa gikomeye, muri - umurongo wo gutangiza umurongo.
Siyanse Yinyuma Yumuti wa Corona: Gukora Ubuso
Ubuvuzi bwa Corona bukora mukugaragaza hejuru ya firime ya plastike hejuru ya - voltage yumuriro mwinshi mumashanyarazi. Uku gusohora gukora plasma ikungahaye kuri electron zifite ingufu, ion, na radicals yubusa hejuru yibikoresho. Uburyo bwibanze bwo kunonosora neza ni kwinjiza ogisijeni - ikubiyemo amatsinda akora ya polar (nka karubone) kumurongo wa polymer binyuze mumyuka ya okiside. Iyi nzira yongerera neza ingufu zubuso hamwe na polarite ya plastike.
Ubuso bwa polarite yongerewe imbaraga buteza imbere imiyoboro ya kabiri ya chimique, nkimbaraga za van der Waals hamwe n’imikoranire ya dipole, hamwe nyuma yo gutwikira, wino, cyangwa ibifatika. Nkuko bigaragazwa nubushakashatsi bwakozwe kuri firime polyethylene, kuvura corona birashobora kongera imbaraga zingirakamaro, hamwe no gupima imbaraga zishishwa ziva kumurongo utari muto kuri firime zitavuwe zikagera kumurongo wingenzi post-. Iri hinduka kurwego rwa microscopique rihoraho kubuzima bwateganijwe bwo kubika ibicuruzwa kandi ni ingenzi cyane kugirango habeho gusohora - yubatswe cyangwa yometseho ibintu bikomeza ubunyangamugayo bwabo.
Ibyingenzi Byingenzi muri Extrusion Coating na Lamination
Gushyira mu bikorwa imiti ya corona ni ngombwa mu bintu byinshi by'ingenzi mu guhindura inzira:
1. Gufata Amashanyarazi:Iyo polymer yashongeshejwe (urugero, LDPE) isohorwa kuri substrate yimuka nkibipapuro cyangwa fayili, kuvura hejuru yubutaka mbere byerekana neza neza no guhuza polymer ushonga. Ibi bisubizo muburyo bumwe, pinhole {{3} ating gutwikira ubusa kubikoresho byo gupakira hamwe na barrière.
2. Filime - kugeza - Kumurika Filime:Kurema ibintu byinshi - byubatswe (urugero, guhagarara - hejuru ya pouches), corona ivura isura imwe cyangwa yombi ya firime ni itegeko kugirango ugere kumurongo ukomeye, urambye ukoresheje ibice bifatanye. Ibi birinda gusiba kandi byemeza ubudakemwa.
3. Gutezimbere Kwandika:Mbere yo gucapa kuri firime ya pulasitike, kuvura corona byemeza ko wino yubahiriza neza kandi ikarwanya guswera cyangwa guhindagurika, ibyo bikaba ari ngombwa mu kubika amakuru yerekana ibicuruzwa no gupakira.
4. Gufata neza imikorere:Mubisabwa bisaba gutwikira imitungo ya barrière (urugero, UV irwanya, gazi ya gazi), ubuso buvuwe butanga inanga ikenewe kuriyi nzego.
Gushyira mu bikorwa inganda n'ibikoresho
Ubuvuzi bwa Corona bwahindutse muburyo bwambere bwo kuvura hejuru yubutaka bwo kuvoma no guhindura inganda bitewe nubwizerwe, imikorere, kandi bikwiranye numurongo mwinshi -. Inzira isanzwe yinjizwa muburyo bwo gukuramo cyangwa guhindura umurongo.
Ibikoresho bisanzwe, akenshi bishingiye kuri sisitemu ya dielectric barrière ya sisitemu (DBD), itangwa nabakora inganda zikomeye ku isi. Abavuzi bagizwe na sisitemu ya electrode hamwe na dielectric - umuzingo utwikiriye ibikoresho byurubuga. Urwego rwo kuvura rushobora kugenzurwa neza muguhindura ibipimo nkimbaraga, inshuro, numuvuduko wurubuga. Kubice bitatu - ibipimo bya pulasitike bikoreshwa mubisabwa bimwe na bimwe, imiti yihariye ya rotora corona nayo yatunganijwe.
Inyungu n'ingaruka zinganda
Gukoresha cyane imiti ya corona bitanga inyungu zifatika nibikorwa byiza:
Kongera umusaruro wibicuruzwa:Ifasha umusaruro mwinshi - imikorere yamuritswe kandi isize ibikoresho hamwe nimbaraga zisumba izindi, ubudahangarwa bwa kashe, hamwe nubwiza bwanditse.
Kugabanya imyanda:Mugukuraho hafi kunanirwa bitewe no kudafatana nabi, nko gusiga nabi, gutwika igishishwa - kuzimya, cyangwa gutandukana kwa laminate, inzira igabanya cyane imyanda yibikoresho hamwe nigihe cyo gukora.
Guhindura Ibikoresho:Iremera abahindura gukoresha igiciro - cyiza, hejuru - imikorere ya polyolefine mugusaba porogaramu zisaba ubundi ibikoresho bihenze cyangwa bigoye.
Kubahiriza n'umutekano:Kubiribwa, ubuvuzi, nubuvuzi bwa farumasi, kwizerwa ntabwo ari - byumvikanyweho kugirango habeho inzitizi zidafite ishingiro no gukumira umwanda, bityo hubahirizwe amahame akomeye y’umutekano.
Kuvura Corona gusohora bikomeje kuba tekinoroji yibikorwa bya plastiki ihindura inganda, bikemura neza ibibazo bikomeye byo gufatira hamwe no gutwika. Muguhindura burundu imiterere yubuso bwa polyolefine binyuze muri okiside no kwinjiza amatsinda ya polar, ifungura ubushobozi bwabo bwose bwo gukora ibintu biramba, bikora, kandi birebire - bifite ireme - ibikoresho byubaka. Mugihe ibyifuzo byo gupakira bikomeje kugenda bihinduka muburyo bukomeye kandi burambye, uruhare rwibikorwa bikomeye kandi bikora neza nko kuvura corona bizarushaho kuba intandaro yo gutsinda.
