Engeri Ebyuma bya Corona gye Bilongoosaamu Amasoboza ag’okungulu okulongoosa okukuba ebitabo mu ngeri ya Laminated
Okunywerera okutuukiridde kwa yinki oba ebizigo ku substrates kikulu nnyo mu high-stakes field of laminated printing. Ekiyungo kino kisalibwawo amasoboza ag’okungulu, ekintu ekikulu naye oluusi ekibuusibwa amaaso. Olw’amasoboza gazo amatono ag’okungulu, firimu za polyethylene (PE), empapula za kraft, ne firimu nnyingi ez’obuveera bizibu okufuka n’okusiba. Kino kye kiseera ekyuma kya Corona eky’okukuba ebitabo mu ngeri ya laminated we kifuuka ekikulu ennyo mu yinginiya. Nga bakyusa ddala engeri z’ebintu eby’okungulu, ebyuma ng’ebyo bikola ku ngulu kwabyo. Kino kyanguyiza okukuba ebitabo, kinyweza lamination bonds, era okukkakkana nga kivaamu ebintu ebisembayo eby’ekika ekya waggulu.
Sayansi w’okukola ku ngulu
Okufuluma kw’amasannyalaze okwa frequency enkulu-kusiigibwa okubuna electrode ne dielectric-covered roller mu kyuma kya Corona okukuba ebitabo mu laminated. Nga bwe kitambula mu kitundu kino eky’okufulumya corona, empewo eyeetoolodde substrate-eyinza okuba omukutu gw’empapula oba firimu ya pulasitiika-ekola ionize n’efuuka pulasima. Ayoni n’obusannyalazo obw’amasoboza amangi- okuva mu pulasima eno bikuba ku ngulu w’ekintu, ne bituukiriza emirimu ebiri emikulu. Okusooka, ziggyawo layers z’ensalo enafu n’obutundutundu obutono okuva kungulu. Ekyokubiri, era mpozzi ekisinga obukulu, zikola ebitundu ebikola ennyo ku ngulu kwa polimeeri nga zikutula enkolagana ezikwata molekyo wamu. Ebifo bino bikola mangu enkolagana ne okisigyeni ow’omu bbanga, ne byongera ebibinja ebikola eby’enjuba (nga ebibinja bya haidrokisi ne kaboni) ku ngulu. Enkola eno eyongera nnyo ku masoboza ag’okungulu ag’ekintu, n’ekikyusa okuva mu mbeera ey’amasoboza amatono, agatali-okusiba okudda mu mbeera ey’amasoboza amangi-, ey’okusiiga esinga obulungi mu lamination n’okukuba ebitabo.
Okugatta n’ebiva mu nkola z’okukuba ebitabo mu ngeri ya Laminated
Waliwo enkola nnyingi ez’okujjanjaba corona, era esobola okukozesebwa ku bitundu eby’enjawulo eby’olunyiriri lw’okufulumya okukuba ebitabo ebikoleddwa mu laminated okukola ku nsonga ezimu.
Pre-Print Treatment: Nga tonnaba kukuba, firimu oba empapula substrate erina okulongoosebwa. Amasoboza ag’okungulu ag’okwongerako gakakasa nti yinki zinywerera bulungi era ne zisaasaana mu ngeri y’emu, ekiziyiza ensonga ng’okusiiga, langi entono, n’okuseeyeeya kwa yinki. Ekintu ekiwedde ekikubiddwa kigumira nnyo okwonooneka, kirina langi ezimasamasa, n’ebifaananyi ebisongovu.
Okuteekateeka Lamination: Okukola ekiyungo ekiwangaala-era ekitamenyeka, kikulu nnyo okujjanjaba substrate emu oba zombi nga tonnaba kukola lamination. Amaanyi g’ebikuta n’obuwangaazi bw’ekizimbe ekikoleddwa mu laminated byongerwa nnyo olw’ekifo ekikola, ekikakasa nti ekyesiiga kirina okukwatagana okusinga obulungi n’okukwatagana kw’eddagala. Oba okozesa enkola ezikwata ku puleesa- oba ebisiiga eby’ebbugumu, kino kituufu. Kino kikulu nnyo naddala ku mirimu egy’amaanyi nga laminate erina okugumira situleesi n’embeera y’obudde, gamba ng’okupakinga okukuuma.
Okutegeka Enkola y’Ebivaamu Ebisinga Obulungi: Abajjanjaba Corona bategekebwa mu ngeri ez’enjawulo okutuukiriza ebyetaago by’okufulumya. Ku layini ezigenda mu maaso, ez'obunene-volume n'okukuba laminating, enkola eziri mu layini zigattibwa ddala mu kkubo ly'omukutu. Kino kisobozesa obujjanjabi ku-the{4}}spot awatali kuyimiriza kukola. Olina ebirala ebirala eby'okukola n'emisinde egy'enjawulo, emisinde egy'ennono, oba emisinde egy'obunene obwa wakati-nga okozesa ebyuma ebijjanjaba corona eby'ekika kya batch-. Nga kisobozesa abaddukanya okutereeza vvulovumenti, frequency, n’obudde bw’okubikkulwa ku buli batch, kikakasa nti buli kintu kifuna obujjanjabi obutuufu era kyanguyiza okukebera omutindo wakati w’okudduka.
Ebirina okulowoozebwako ku Bukuumi n’Omutindo
Olina okulondoola buli kiseera ebintu ebiwerako eby’emirimu n’eby’ekikugu okusobola okufunamu ennyo mu kyuma kya Corona okukuba ebitabo mu ngeri ya laminated. Okufuna amasoboza ag’okungulu agaagala (agatera okupimibwa mu dynes/cm) awatali kwonoona substrate nga ogijjanjaba ekisukkiridde-, olina okuba n’obuyinza obutuufu ku parameters z’okulongoosa nga power density (watts per square foot), electrode gap, ne web speed. Okugatta ku ekyo, okulabirira ebyuma bino kikulu nnyo. Kuno kw’ogatta okuyonja obuuma obuyitibwa electrodes ne dielectric rollers buli kiseera okuyimiriza arc-outs n’okukuuma eriiso ku miwendo gya ozone. Kino kiri bwe kityo kubanga okufuluma kwa corona kukola ozone, eyeetaaga okufulumizibwa obulungi okuva mu kifo we bakolera. Okugoberera enkola zino ennungi tekikoma ku kukakasa nti ebintu biba bya mutindo gwa waggulu, naye era kifuula ekifo we bakolera okuba eky’obukuumi eri abakozi.
Mu bufunze, ekyuma kya Corona eky’okukuba ebitabo mu ngeri ya laminated kitundu kikulu nnyo mu kukuba ebitabo okw’omulembe mu laminated ekisobozesa okufuna omutindo ogwa waggulu. Kigonjoola ebizibu by’okunywerera ebintu bingi ebipakinga n’okukuba ebitabo bye birina nga kirongoosa mu ngeri ya ssaayansi amasoboza ag’okungulu aga substrates. Tekinologiya ono akosa butereevu enkola y’ebintu, okumatizibwa kwa bakasitoma, n’obulungi bw’okukola ng’akola ebiwandiiko ebitangaala era ebiwangaala-ebiwangaala n’ebikozesebwa ebikoleddwa mu laminated ebinywevu era ebyesigika. Nga ssaayansi w’ebintu agenda atereera n’obwetaavu bw’okuyimirizaawo bwe bweyongera, obusobozi bw’okukola obulungi era mu ngeri efugibwa ku ngulu bujja kweyongera okuba obukulu eri ebirowoozo ebipya mu makolero g’okukuba ebitabo n’okupakinga.
