Tekinoroji yePepa Rakanyoroveswa rePaperjoy Deciphers Core: Kurapwa kweCorona Kunovandudza Sei Kunamira kwePE Coating?
Mukugadzirwa kwe bepa repurasitiki rinoputirwa chikafu, PE coating adhesion inosarudza zvakananga kugara kwenguva refu uye kuchengetedzeka kwechigadzirwa, uye chiratidzo chikuru chekuyera Pepa Rakaviriswa mhando.PaperjoyPepa (Nanning Paperjoy Paper Co., Ltd.) rave richitengesa kunze kwenyika zvinhu zvepurasitiki zvakaputirwa nepepa. Nhasi, rinoongorora tekinoroji yekutanga yekugadzirira kuputirwa neropa – kurapwa kwekorona, richiratidza kuti rinovandudza sei kunamatira kwePE coating uye kudzivirira zvikanganiso zvechigadzirwa.
Kurapwa kweCorona inzira huru yekutanga kurapwa kwechirwere ichi bepa rakanamirwakugadzirwa, nepfungwa yakajeka: Simba remagetsi rine mafrequency akawanda uye high-voltage (voltage 5000-15000V/㎡) rinoshandiswa pakati pe electrode yekuburitsa uye roller yekurapa korona yakatsaurirwa (yakagadzirwa ne silicone rabha kana ceramic, ine resistance yepamusoro-soro, resistance ye ozone uye insulation yakasimba). Kana voltage ikapfuura nepakati pe ionization resistance ye 1-2mm air gap, mhepo inoiswa ionized kuti igadzire huwandu hwakawanda hwe ozone. Ozone inooxidize mamorekuru epamusoro epurasitiki kuti igadzire carbonyl compounds uye peroxides. Panguva imwecheteyo, plasma inokanganisa pamusoro pefirimu, ichipwanya cheni dzepolymer uye ichikonzera oxidative cross-linking reactions – pakupedzisira inovandudza zvakanyanya kushushikana kwepamusoro pefirimu uye inowedzera zvakanyanya kunamira kwemaitiro anotevera ekudhinda, gluing uye lamination.
Chikwata chehunyanzvi chaPaperjoy chinotaura kuti kushandiswa kwemishonga yekurapa corona kunoda kuti munhu anzwisise zvinhu zviviri zvinokosha:
①Mhepo yakasimba uye simba: Mhepo inofanira kugara ichichengetwa pamusoro pe6KV uye simba risingasviki 6KW. Kunyanya panguva yekuburitsa lamination, zvinhu zvepasi zvinofanira kurapwa ne corona yepamusoro. Kusakwana kwemagetsi kana kusakwana kwekugadzirisa kuchaita kuti zvinhu zvepasi zvisakwane, zvichikonzera zvikanganiso zvakaita sekubviswa kwePE coating uye delamination.
②Kuchenesa pamusoro: Kurapa kweCorona kunogona kubvisa mafuta, hunyoro netsvina panguva imwe chete pamusoro pefirimu, kubvisa zvipingamupinyi zvemaitiro anotevera ekunamatira, kunatsiridza kunamira kweinki yekudhinda uye kuderedza mwero wekukanganisa kwezvigadzirwa zvakapedzwa.
Zvichibva pakutsvagurudza kwakadzama pahunyanzvi hwemapepa epurasitiki, Paperjoy yakagadzira sisitimu yekurapa corona yakakura uye mitemo inoshanda yekushanda. Inogona kupa rutsigiro rwehunyanzvi rwakagadziriswa kumabhizinesi ekupakata chikafu pasi rese zvichienderana nezvinhu zvakasiyana, zvinhu zvePE uye zvinodiwa nezvigadzirwa, kusanganisira kugadzirisa corona treatment parameter optimization, mazano ekugadzirisa zvinhu zvepurasitiki uye zvirongwa zvekuvandudza maitiro emhando yepamusoro, kugadzirisa nemazvo matambudziko ekugadzirwa kwevatengi. Kuti uwane mhinduro dzehunyanzvi kana bvunzo dzemuenzaniso, ndapota shanyira webhusaiti yepamutemo yePaperjoy pa www.paperjoypaper.comkuti vabvunzurwe.
