Itekhnoloji yokugquma kunye nokuLaminating ye-Hot Melt Adhesive kwiShishini lezonyango

Ngophuhliso lwesayensi netekhnoloji, izixhobo ezininzi ezisebenzayo kunye neemveliso ziyavela kwimarike. I-NDC, ihambelana neemfuno zokuthengisa, isebenzisana neengcali zonyango kwaye iphuhlise izixhobo ezahlukeneyo ezikhethekileyo kwishishini lezonyango. Ingakumbi ngexesha elibalulekileyo xa i-COVID-19 itshabalalisa ihlabathi kwiminyaka emithathu edlulileyo, i-NDC ibonelela ngoomatshini abaqinileyo ukuqinisekisa abavelisi abavelisa izixhobo zokukhusela kwishishini lezonyango. Sikwafumene ukuqatshelwa okuphezulu kunye nendumiso kuluntu kumashishini amaninzi ezonyango nakurhulumente.

Inkqubo yeteknoloji yokugquma ye-NDC inokwahlulwahlulwa ngeendlela ezintathu, sikhetha iteknoloji yokugquma engcono ngokweemfuno zomsebenzi wemveliso kunye neempawu zokuncamathelisa.

1. Itekhnoloji yokuGqithisela iGravure Anilox Roller Transfer Coating

I-Gravure Anilox Roller coating yindlela yendabuko yokugquma, njengetekhnoloji yokuprinta i-gravure. I-hot melt adhesive ifakwa kwilaphu elingalukwanga nge-anilox roller eqoshiweyo ene-slot scraper. Yindlela yokugquma engenakutshintshwa yetekhnoloji yokugquma enepateni, enokufezekisa imfuno yokuphefumla.

Nangona kunjalo, ukuba ufuna ukulungisa ubungakanani be-glue coating, kuya kufuneka utshintshe i-coating roller ngee-anilox rollers ezahlukeneyo ezinzulu nezimile ngendlela eyahlukileyo.

Indlela yokugquma i-Anilox roller ifanelekile kwiintlobo ngeentlobo zeglu, kuquka ne-PUR adhesive, elula ukuyicoca. Ezinye iglu ezinyibilikayo ezishushu zinyibilikiswa lula yile ndlela yokufudumeza evulekileyo.

2. I-Spray (i-adhesive ye-spray engaqhagamshelwanga) Itekhnoloji yokwaleka

Ukutshiza nge-spray coating yindlela eqhelekileyo yokutshiza. Kukho iintlobo ezimbini ze-spray guns: i-spiral spray gun encinci kunye ne-fiber spray gun.

Inzuzo kukuba inokutshizwa ngqo kwizinto ezingamelaniyo nobushushu obuphezulu, kwaye izixhobo zinomoya ovulekileyo, kwaye kulula ukulungisa ubunzima kunye nobubanzi bokutshiza. Le yinzuzo yesibhamu sokutshiza. Ingxaki kukuba umlomo uya kuvalwa ngokungenakuphepheka kwaye kungabi lula ukuwucoca, kwaye kwinkqubo yokuvelisa kuya kubakho ukuvuza kwe-spray kunye ne-glue drop phenomena, eya kubangela iziphene kwimveliso. I-spray coating ayikhuthazwa kwi-PUR hot melt adhesive.

3. Iteknoloji yoQhagamshelo lweSlot Die Breathable Coating

I-contact slot die breathable coating yindlela ephucukileyo yokugquma enokuhlangabezana nobungakanani obuphantsi beglue coating ukuya kubungakanani obuphezulu bokugquma. I-coating ifana kakuhle, i-lamination flat, kulula ukuyilungisa ubunzima beglue kunye nobubanzi beglue. Isetyenziswa kakhulu kwimigca yemveliso yokugquma kunye ne-laminating yezinto zokunxiba zokwahlukanisa/izinto zeteyiphu zonyango ezizincamathelayo, izinto zokuncamathisela zokunxiba zonyango, izixhobo zeplasta yezonyango njl.njl.

I-NDC ifikelele kububanzi bomatshini obuphezulu obuyi-3600mm kubathengi. Isantya sokugquma i-Anilox Roller coating yi-200m/min, isantya sokugquma i-spray esingachukumisiyo yi-300m/min kwaye isantya sokugquma esiphefumlayo esichukumisayo yi-400m/min.

Ubuchwepheshe bufuna imvula, amava kufuneka aqokelelwe, amandla okuvelisa afuna utyalo-mali.

I-NDC isoloko inamathela kwinjongo yayo yokukhuthaza uphuhliso lweteknoloji yokutshiza kunye nokufaka i-hot melt adhesive. Sizinikele ekuboneleleni ngezixhobo ezikhethekileyo kunye nezisombululo zobugcisa kwizicelo ze-hot melt adhesive kumashishini ahlukeneyo.
