Kuisa lamination isina solvent kwakura mumusika, kunyanya nekuda kwekuedza kwemakambani ekurongedza nevatengesi vezvinhu, kunyanya tekinoroji yekuisa lamination yealuminium yakachena yekudzoreredza zvinhu yave kufarirwa zvakanyanya, uye yatora danho guru pasi pemamiriro ezvinhu ezvakatipoteredza ekutsiva kugadzirwa kwelamination yechinyakare uye kugadzirwa kwelamination yakaburitswa. Makambani ekurongedza anosangana nematambudziko akasiyana-siyana emhando nekuda kwemamiriro akasiyana ezvigadzirwa mumichina, mashandiro, zvinhu zvakagadziriswa, tekinoroji yemhando yepamusoro uye mashandisirwo. Pepa rino richataura nezvedambudziko riripo, iro, kugona kwebhegi kuvhurika uye kutsetseka kwaro.
Semuenzaniso, firimu repolyethylene rakaburitswa nezvikamu zvitatu rinoumbwa nechikamu che corona, chikamu chepakati chinoshanda uye chikamu chepasi che thermal seal. Kazhinji, zvinhu zvinovhurwa uye zvakapfava zvinowedzerwa kune chikamu chinopisa che sealing. Chinhu chinopfava chinotamiswa pakati pezvikamu zvitatu, uye chinhu chinovhurwa hachiwedzere.
Sechinhu chinovhara zvinopisa, zvinhu zvinovhura uye zvinotsvedzerera zvinodiwa pakugadzira zvinhu zvinochinjika pakurongedza. Zvakasiyana zvachose, asi vagadziri vazhinji vemapakeji havanzwisisi kuti zvakafanana.
Chinhu chinowanzo vhurwa chinowanikwa muzvitoro chinonzi silicon dioxide, inova chinhu chisiri cheorganic chinogona kuwedzera simba remufirimu kuti usanyanya kusviba. Vamwe vatengi vanogara vachiona kuti zvikamu zviviri zvepachikwama zvinoita sezvisina kujeka pakati pazvo, kungofanana nemagirazi maviri anopindirana. Uchaona kuti zviri nyore kuvhura nekupukuta, izvo zvinowanzo shaikwa mune zvimwe zvinovhurwa. Uye kunyange vamwe vagadziri vemafirimu havazvishandisi.
Chinhu chinowanzo smooth additive iErucic acid amide, inova hupfu huchena hunowanzo namatira kune lamination roller uye guide roller mu solvent-base laminating process. Kana smooth agent yakawandisa ikawedzerwa panguva ye solvent-free laminating process, imwe inopararira kusvika ku corona layer sezvo tembiricha yekupisa ichiwedzera, zvichikonzera kudzikira kwesimba rekukwesha. Firimu rekutanga re lamination transparent PE rakakweshwa nechena, rinogona kupukutwa ne tissue. Pane nzira yekuongorora nekuyedza kana kudzikira kwesimba rekukwesha kuchikanganiswa nekuwanda kwezvinowedzera zvakapfava, kuisa firimu re laminate rakasimba muovheni pa80℃ kwemaminitsi mashanu, uye wobva waedza simba racho. Kana rikawedzera zvakanyanya, zvinogumiswa kuti kudzikira kwesimba rekukwesha kunokonzerwa nekuwanda kwezvinowedzera zvakapfava.
Kana tichienzanisa nekudzoreredza solvent-base lamination, nzira yekudzoreredza solvent-free lamination iri nyore kwazvo kuwana kuwedzerwa uye kupararira. Nzira yakajairika yekuongorora solvent free laminating rewind ndeyekutarisa kuti dzakatetepa uye dzakachena zvakakwana kuti zvibvumire kufamba kwakanaka kwechipiri kweglue-free-solvent. Kana firimu roller ikamanikidzwa zvakanyanya, chinowedzera chinotsvedza chinogona kutamira kune laminated layer, kana kunyange printing layer. Saka, tinoramba tichivhiringidzika nezvenyaya iyi. Chatinogona kuita kuderedza tembiricha inopora, kuderedza huremu hwekufukidza, kusunungura firimu, uye kuwedzera zvimwe zvinowedzerwa zvakapfava kakawanda. Asi pasina kudzora kwakanaka kwezviri pamusoro apa, glue inonetsa kurapa uye inochengeta mvura. Zvimwe zvinowedzerwa zvakawanda hazvingokanganisi simba rekukwesha kwepurasitiki chete, asiwo zvinokanganisa mashandiro ayo ekupisa.
KANDA NEW MATERIALS yakaburitsa nhevedzano yezvinonamatira kugadzirisa matambudziko aya. Chinonamatira cheWD8117A / B chine zvikamu zviviri chisina zvinonamira chinokurudzirwa zvakanaka. Chave chichisimbiswa nevatengi kwenguva yakareba.
| Maumbirwo | Chiyero chekutanga chekukweshana | Kukweshana kwakapetwa ne laminated |
| PET/PE30 | 0.1~0.15 | 0.12~0.16 |
WD8117A / B inogona kushandiswa kugadzirisa dambudziko rekusasimba zvakanaka kwekubvisa mavanga uye kushanda zvakanaka kwekupisa nekuda kwekuwedzera kwakanyanya kupfava pamusoro pasina kuda kuti mugadziri wefirimu rekutanga azvideredze.
Pamusoro pezvo, WD8117A/B ine zvimwe zvinhu zviviri:
1. Simba rekukwesha reOPP / AL / PE riri pamusoro pe3.5 N, riri pedyo kana kuti rakakwirira kupfuura mamwe manamatisi elaminating ane solvent-base.
2. Kukurumidza kupora. Pasi pemamiriro ezvinhu akakurudzirwa, firimu rekuisa laminating rinogona kupfupisa nguva yekupisa kwemaawa angangoita masere, izvo zvinowedzera kushanda zvakanaka kwekugadzira.
Mukupfupisa, kusarudzwa kwekupedzisira kwe friction coefficient ye composite film kunofanirwa kubva pama static friction coefficients ari pakati pefirimu nesimbi. Mafungiro asiri iwo ekuti zvakaoma kuvhura homwe nekuti hapana zvinowedzerwa zvakakwana zvinofanirwa kuonekwa nekugadziriswa. Tinogona chete kuwana kugadzikana uye zvigadzirwa zvepakeji zvinochinjika zviri nani kuburikidza nekupfupisa kwega kwega uye kugadzirisa.
