Basa Rakakosha reSurface Energy
Munzvimbo yemakwikwi yedhijitari uye yedhijitari yedhijitari, kuwana mhando yepamusoro yekudhinda, kunamatira, uye kusimba kwakakosha. Kiyi, asi kazhinji iri pasi-yakagadziridzwa, chinhu mukutsvaga uku isimba repamusoro re substrate. Sheet-zvishandiso zvakavakirwa, kubva pamapepa akavharidzirwa nemafirimu ekugadzira kusvika kune mapolymer anogona kuodza, anowanzoratidza simba rakaderera, zvichiita kuti kusanyorova uye kunamira kweingi nemabhachi. Corona discharge treatment yakagara yakasimbiswa senzira inoshanda kwazvo yekugadzirisa pamusoro kugadzirisa dambudziko iri. Nekupa inodzorwa plasma kurapwa, corona varapi vanowedzera simba repamusoro rezvinhu, nekudaro vachishandura kudhinda uye kuita kwavo.
Kunzwisisa Zvinokosha Kurapa Corona
Kurapwa kweCorona inzira yekunatsiridza pamusoro inoshandisa-tembiricha yekuburitsa corona plasma kupa shanduko muhunhu hwenzvimbo. Maitiro acho anosanganisira kugadzira munda weplasma pakati pe electrode uye roller yakadzika pamusoro peiyo substrate inopfuura. Iyi plasma inodyidzana nepamusoro peiyo substrate, ichigadzira mapoka anoshanda epolar (senge carbonyls uye mahydroxyls) ayo anowedzera zvakanyanya pamusoro pesimba uye kuwedzera kunyorova. Pamaapplications ekudhinda, izvi zvinoturikira kune mamwe mayunifomu inki kuisa pasi, yakasimba kubatana, uye nekunatsiridza kukurumidza kudhinda.
Kubudirira kwekurapa kunoyerwa mu dynes/cm (pamusoro pesimba). Mafirimu epolymer asina kurapwa, semuenzaniso, anogona kunge aine simba repamusoro rakadzika se30-35 dynes/cm, nepo kudhinda kwakaringana kuchiwanzoda mazinga ari pamusoro pe40-50 dynes/cm. Kurapa kweCorona kunogona kukwidziridza hunhu uhu kusvika padanho rinodiwa, zvichiita kuti kunyange inki dzinonetsa dzemvura-dzinonamatira zvinobudirira kune substrates sepolylactic acid (PLA).
Optimization Parameters yeSheet-Maererano neMa substrates
Kunatsiridza marapirwo e corona hakuna-saizi imwe-inokwana-zvese. Pamashizha-anodhinda padhijitari nedhijitari, zvakati wandei zvakakosha zvinofanirwa kucheneswa:
1. Substrate Kuumbwa uye Porosity:Chiyero chekurapa chinofanira kufananidzwa nezvinhu. Mafirimu asiri{{1}asina porous synthetic films (eg, PET, OPP) anoda kurapa kwakasiyana pane maburi, mapepa akavharidzirwa kana biodegradable fibrous webs. Kupfuura{{5}bepa rekurapa kunogona kukanganisa mafiibha, ukuwo -pamafirimu ekurapa achizopa kusanamira zvakanaka.
2. Kurapa Simba Density (Watts/ft²/min):Iyi ndiyo core parameter inodzora dhigirii rekugadziriswa kwepasi. Higher power density inowedzera simba repamusoro zvakanyanya. Makorona emazuva ano anorapa ane -ane powered ceramic electrode anobvumira kunyatso kudzora pamusoro pekuchinja uku, zvichiita kuti optimization yeimwe substrate neingi misanganiswa.
3. Electrode Dhizaini uye Sistimu Kugadziriswa:Sarudzo yepakati peyakagadziriswa-kufara uye yakakamurwa maelectrodhi yakakosha pashizha-pakugadziriswa. Maelectrode akakamurwa anobvumira kurapwa kwepateni kana zonal control, izvo zvakakosha pakurapa nzvimbo dzakati dzebepa kana kugonesa hupamhi hwewebhu hwakasiyana-ku{4}mashandisirwo emapepa. Hunhu hwechifukidziro chedielectric pane yepasi roller zvakare hunokanganisa zvakanyanya kuenderana kwekurapa uye inoderedza zvingangoita arcing kana substrate kukuvara.
4. Kurapa Kufanana uye Kuchembera:Mabatirwo anoenderana pese pese mapepa akakosha pamhando yekudhinda yakafanana. Pamusoro pezvo, mashandiro ekurapa corona anogona kudzikira nekufamba kwenguva-chiitiko chinozivikanwa se "kuchembera." Kugadziridza kunosanganisira kuona kuti chiyero chekurapa chakakwana kuchengetedza kunamatira kwakaringana mukati mekudhinda, kupfekedza, uye kupera-kushandiswa kwehupenyu hwechigadzirwa.
5. Kubatanidzwa ne Press Lines:Kuti zvinyatsoshanda, varapi vekorona vanofanirwa kubatanidzwa zvisina mutsetse mutsetse wekudhinda, kazhinji wakamisikidzwa pamberi pechiteshi chekudhindisa kana chekupotera. Izvi zvinoita kuti substrate iri muchimiro chayo chekugamuchira kana ichisangana neingi.
Mabhenefiti ekushandisa mudhijitari uye Offset Kudhinda
Iko optimization yekurapa kwekorona inopa mabhenefiti anobatika kune ese ari maviri makuru matekinoroji ekudhinda:
Zvekudhinda Offset:Inoita kuti mafuta agare zvakanaka{{0}mainki nemabhachi kune akasiyana siyana-mashizha emafuta, anosanganisira UV-mapepa akaiswa uye akagadzirwa. Izvi zvinoderedza kukweshwa kweinki-kunosimudzira kupenya kweruvara, uye zvakakosha pakurongedzerwa kwemhando yepamusoro{5}uye kudhindwa kwekutengesa.
Zvekudhinda Digital (semuenzaniso, HP Indigo, Inkjet):Ingi zhinji dzedhijitari, kunyanya dzemvura{{0}dzepamusoro nedze latex ingi, dzine tension yakakwira uye inonetsekana nekuramba iine simba rakaderera-. Kurapwa kweCorona kwakakosha pakugonesa-kudhinda kwemhando yepamusoro pamafirimu ekurongedza, mavara, nemabhodhi ehunyanzvi, kuwedzera huwandu hwemashandisirwo emuchina wedhijitari.
Kugonesa Sustainable Materials:Sezvo indasitiri inochinja ichienda kune biopolymers sePLA, kurapwa kwecorona kunopa nzira yakasimba yekupa izvi zvakasikwa zvehydrophobic zvinhu zvinodhinda. Izvi zvinotsigira kutorwa kwemamwe ma substrates akasimba pasina kukanganisa kudhinda kuita.
Mhedziso uye Maitiro Akanakisisa
Kunatsiridza marapirwo ekorona kumashizha{{0}anobva masubstrates imari inyanzvi inoenderana nemhando yakadhindwa, kushanda zvakanaka kwekugadzirwa kwezvinhu, uye kuita zvakasiyana-siyana. Kubudirira kunotsamira pakubatana nevapi vemidziyo vane ruzivo vanogona kupa mhinduro dzakagadzirirwa zvichienderana nehunyanzvi hwekushandisa. MaPrinter anofanirwa kuita yenguva dzose dyne level kuyedzwa kutarisa kushanda kwekurapa uye kugadzirisa masisitimu avo zvinoenderana. Nekuona marapirwo ekorona kwete sechishandiso chete asi semagadzirirwo ekuita, maprinta anogona kuvhura mashandiro epamusoro kubva kune ese masubstrates awo nemashina, achisangana ne-zviri kuramba zvichiwedzera zvinodiwa zvemhando uye hunyanzvi muindasitiri yemifananidzo.
