Jafe-jafe adhésion ci emballage contemporain
Am produit bu baax te yàgg lu am solo la ci àdduna bi, di emballage yu yomb ak impression lamine. Delamination, wala tàqale ay couche laminée, xeetu gacce la buy gàllankoor defarkat yi, ba noppi di yàq kalite barrière yi, appel estetik bi, ak mujjee ci kaaraange produit bi. Energie surface bu néew mooy màndarga biy faral di indi jafe-jafe yii, boole ci fi yaxxu ci imprimante bi lu ci melni encre buy frotte ak resolusioŋ bu néew. Filmu polymer yu bari yu ñuy jëfandikoo ci emballage, lu ci melni polyethylene (PE) ak polypropylene (PP), mënu ñu lëkkaloo ak encre, revêtement ak adhésif ndax dañuy inert ci wàllu chimie te duñu am porose ci nature bi. Caabi, liggéeyukaay -standard tontu ci jafe-jafe bii mooy xaralay pajum corona, biy mëna aktive surface macceer ngir moytu ay fippu ak garanti performance bu gëna baax.
Science ci pajum Corona: Yokkatal lëkkaloo gi ci def surface yi
Decharge électrique bu am voltage bu kawe, fréquence bu kawe lañuy jëfandikoo ci pajum corona, muy pexem soppi surface bi, ngir yokk energie surface bi ci substrat yi. Energie biy jaar ci zone decharge corona bi dafay indi jafe-jafe ci structure moleculaire bi ci surface matériel bi, muy defar ay site yuy reaktif ba noppi yokk hydrophilité bi. Yooyu gëna mëna tooy lu am solo la ndax dafay tax coating yi, adhésif yi ak encre yi mëna séddale ci anam wu maase ay mbir, ba noppi ñu jegewaale substrat bi, loolu mooy jur interaction chimique ak mechanique yu gëna am doole.
Njariñu liggéey boobu du yàgg. Suñu sukkandikoo ci anam wi ñu koy denc, ay yokk-yokk ci biir filmu polymer bi mën nañu dem ba ci kaw surface bi wàññi energie surface biñ toppatoo ci ay waxtu, ayu-bis wala weer yu néew. Kon dañu wara dugal pajum corona ci ligne de production bi, gëna wóor balaa ñuy jëfandikoo encre wala kol, ngir lamination ak imprime bi gëna baax.
Li am solo ci liggéeyum lamination
Ci tabax yu bari ay couche, delamination dafay am su lëkkaloo bi am ci digganté couche yi dagg. Ni ñuy garantie ni energie surface substrat bi dafa ëpp bu adhésif bi wala couche bi ci wetam, pajum corona bi dafay nekk liiñ bu njëkk ci kaaraange ci gaañ-gaañu bii, ba noppi di jàppale adhésion interlayer bu dëgër.
Laata ñuy njëkka defar lamination extrusion: Balaa substrat bi (lu melni këyit, foil, wala film) di laal rido polymer biy seey, dañu koy njëkka defar ak corona treater. Ngir extrudat bi mëna tooy bu baax ba noppi mën nekk ci substrat bi, fàww ñu def ko.

Njàngale ci parametre yi ngir wóor: Kontrôle bu jaar yoon mooy li am solo ngir paj mi mëna am njariñ. Ci misaal, ngir am tension surface bu doy ci lamination extrusion, fàww nga am voltage bu ëpp 6KV ak doole bu doy (lu melni, bu gëna néew 6KW). Tension surface bu woyof mingi aju ci pajum bu jaarul yoon, te loolu mën na indi ay jafe-jafe yu melni PE coating buy xoosu ak delamination. Rax ci dolli, corona bi dafay setal surface bi ci dindi impureté yi, diw yi ak guus yi, loolu mooy dindi bépp luy tere adhésion bi nekk.
Yokkatal kalite impression bi ak dindi ay fi yaxxu ci impression bi
Ngir imprime bu baax, pajum corona amna solo ni lamination. Encre bu baaxul ci kaw substrat bu am energie surface bu néew mën na jur ay jafe-jafe yu bari.
Encre bu gëna baax ak tànneef yi: Pajum Corona dafay garanti ni encre yi dañuy gëna dëgër ci substrat bi, moytu smudging, flaking, ak fading ci yokk niveau dyne, natt energie surface.
