Kugera ku gukomera gukomeye kandi kwiringirwa hagati yibikoresho bitandukanye biracyari ikibazo gihoraho mubice byubwubatsi hamwe ninganda zikora plastike. Bitewe nububasha buke bwo hejuru, plastike nyinshi - zo gukora - zifite agaciro kubera ubukana bwazo no kurwanya imiti - ni hydrophobique kandi bigoye guhuza, gucapa, cyangwa ikote. Gusiba, gusobanura nabi ibisobanuro, no kugabanuka kwuburinganire bwimiterere mumateraniro yarangiye ni bike mubibazo bishobora guturuka kubibujijwe shingiro. Inganda zakoresheje guca - tekinike yo guhindura isura kugirango izenguruke iyi nzitizi. Muri ibyo, kuvura corona byahindutse ikoranabuhanga ryingenzi mu kuzamura imbaraga za plastike zihuza imbaraga, zitanga igisubizo kinini, cyiza, ndetse n’ibidukikije -.
Ubumenyi bwo kuvura Corona kuri plastikiUbwoko bwo kuvura plasma yo mu kirere bwitwa corona kuvura bukora mugukora amashanyarazi menshi - yumuriro w'amashanyarazi hejuru ya electrode hamwe numuzingo wubutaka substrate ya plastike inyuramo. Hatabayeho guhindura ibintu byinshi biranga ibintu, ubu buryo burahindura cyane ubuso bwibintu kurwego rwa microscopique. Umwuka ukikijwe na ionisiyonike isohoka, itanga plasma irimo radicals yubusa, ion, na electron zifite ingufu. Iyo iyi plasma yinjiye hejuru ya plastike, isenya imigozi ya molekile kandi ikongeramo amatsinda yimikorere ya polar, cyane cyane karubone, hydroxyl, na carboxyl. Imikorere yikoranabuhanga iterwa niyi nzira ya okiside. Ubuvuzi bwa Corona buhindura inshuro imwe - inert, itari - hejuru yinkoni ihinduka imwe yitabirwa cyane mukuzamura polarite nimbaraga. Ubushuhe bwiyongera cyane kurubuga rukora rwakozwe nitsinda rishya ryakozwe. Nkigisubizo, ibifuniko, laminate, ibifata, hamwe na wino birashobora gukwirakwira cyane kandi bigatera imbaraga zikomeye za chimique na physique hamwe na plastike ya plastike. Ihuriro ryiza ryabonetse muburyo bwo kwemeza isano iri hagati yimikorere yimikorere yibikorwa mumatsinda yavuwe hamwe nimbaraga zavuyemo.
Ibyiza byingenzi bya plastiki yibikoreshoGukoresha imiti ya corona itanga inyungu zigaragara, zinyuranye zikemura ibibazo byingenzi byumusaruro. Iterambere ryinshi mumbaraga zingirakamaro ninyungu nyamukuru. Kuvura Corona byemeza intera yizewe kubikoresho bikomatanya, birinda gutandukanya ibice no kongera igihe cyibicuruzwa mugihe plastiki ihujwe nizindi polymers, ibyuma, cyangwa imyenda. Porogaramu kuva kumiterere yimodoka igizwe nuburyo bworoshye bwo gupakira ibintu biterwa nibi. Ubuso buvuwe butuma ibipfundikizo bisumba byose, amabara agaragara, hamwe nigishushanyo mbonera mugucapa no gutwikira. Hafi ikuraho burundu inenge zisanzwe zirimo pinholing, coating delamination, hamwe na wino yikurikiranya, bigabanya imyanda yibikoresho hamwe nogusubiramo amafaranga. Gukoresha impuzu zikora zitanga inzitizi zirwanya ogisijeni, ubushuhe, cyangwa imiterere yumuriro wamashanyarazi bisaba guhora hejuru yubutaka bwa plastiki zikoreshwa mubipfunyika ibiryo cyangwa ibikoresho bya elegitoroniki. Shira kumurongo mubikorwa byo gutunganya nka firime, gucapa, cyangwa kumurongo wa laminating birashobora gushiramo byoroshye kuvura corona ya none. Ibi bivanaho gukenera icyiciro cyihariye - icyiciro cyo gutunganya kandi bigafasha gukomeza, kuri - - gutegura isazi yubutaka, byemeza ubuziranenge buhoraho. Amashanyarazi menshi, nka polyester, polyakarubone, polyolefine (polyethylene, polypropilene), na nylon, arashobora gukoreshwa nubu buryo.
Inganda zikoreshwa mu nganda nibikoresho - Ibisubizo byihariyeKuvura Corona ni ingirakamaro mu nganda zitandukanye aho ibice bya pulasitiki ari ngombwa. Murwego rwo gupakira, iyi niyo porogaramu izwi cyane. Kugirango wizere neza gupakira, gushimisha ubwiza, no gukora inzitizi, firime ya polyolefin (nka PE na PP) isanzwe ikoreshwa na aluminium cyangwa izindi polymers mbere yo gucapa cyangwa kumurika. Mu binyabiziga no mu kirere, guhuza neza intera irakenewe kubintu bitaremereye, bikubiyemo fibre - polymer zishimangirwa. Iyo ibice bigizwe nibikoresho nka polypropilene igizwe na corona ivurwa, imbaraga zo guhuza imbaraga zishimangira gushushanya nyuma, gutwikira, cyangwa guterana hamwe nibindi bikoresho. Ku myenda no kudoda, polyester na polypropilene ni ingero zimyenda yubukorikori ari hydrophobique kandi bigoye kurangiza cyangwa gusiga irangi. Gufatisha imyenda ikora cyangwa laminate, kwihuta kwamabara, no gufata irangi byose byanozwa no kuvura corona kuvura imyenda cyangwa idoda. Muri elegitoroniki, kugirango yemeze neza neza ibyapa byumuzunguruko, ibifuniko bikingira birinda, hamwe na labels, ibice byuzuye bigizwe na polymers yubuhanga nka PET cyangwa PC bakorerwa corona. Kuri fibre yo hejuru -, kuvura corona nintambwe yingenzi muguhindura chimie yubuso bwibikoresho bigezweho, nka firime polyimide cyangwa poly (p - phenylene benzobisoxazole) (PBO) fibre, kugirango bishoboke gukomera cyane mubisumizi murwego rwo hejuru -. Kuvura Corona kubiyigize birashobora no kugira ingaruka kuri rheologiya yo gutunganya ibiti bya fibre / polyethylene yibiti, bikagabanya ubukonje bwashonga ndetse wenda bikanatezimbere nkuko ubushakashatsi bubyerekana.
Gushyira mubikorwa hamwe nibikorwa byizaGutegura neza birakenewe kugirango imiti ya corona ishyirwe mubikorwa neza. Guhuza ibikoresho bya pulasitiki nibisubizo byabigenewe, ibipimo byingenzi birimo guhitamo ingufu zingana, gahunda ya electrode, n'umuvuduko wo kuvura. Mbere yo kohereza - igipimo cyuzuye, birasabwa cyane kwemeza igenamigambi ryo kuvura binyuze mu igeragezwa ukoresheje ingero z'umusaruro. Byongeye kandi, kubungabunga ibikoresho - kugira isuku ya electrode no kwemeza ingufu zituruka - ni ngombwa kugirango tubone ibisubizo byizewe, byororoka. Kugirango bongere imikorere ya sisitemu nigihe cyo hejuru, abakoresha bagomba kubona amahugurwa kubijyanye no gushyiraho neza, inzira z'umutekano, hamwe no gukemura ibibazo by'ibanze.
UmwanzuroKunoza imikorere yimikorere ya plastike, kuvura corona gusohora ni - na - ikoranabuhanga ryukuri, ryiza, kandi ryingenzi. Imbaraga zo guhuza imbaraga, gucapa neza no gutwikira neza, hamwe no kongera ibicuruzwa biterwa ninganda nyinshi byose birashoboka mugusobanukirwa na chimie yo hejuru ya plastiki. Akamaro ko kuvura corona mukwemeza uburinganire bwimiterere nitsinzi ryimikorere yo hejuru -, ibintu byinshi - ibikoresho biziyongera gusa mugihe ibyo bikoresho bizamuka. Kwinjizamo ubu buryo bwo gukoresha tekinoroji ni intambwe yingenzi iganisha ku bwiza no guhanga udushya ku ba injeniyeri n’abakora inganda bashaka kugabanya imipaka y’ibyo bintu bya pulasitiki bishobora gukora.
