M'munda wa zosungunulira zopanda zosungunulira, kutentha kwambiri kwakhala vuto lovuta zaka zingapo zapitazi.Pamodzi ndi chitukuko cha zida, zomatira ndi matekinoloje, zosungunulira-free laminating kwa pulasitiki ndi pulasitiki pansi 121 ℃ retorting wapeza ntchito kwambiri pakati opanga ma CD osinthasintha.Kuphatikiza apo, kuchuluka kwa mafakitale omwe amagwiritsa ntchito PET/AL, AL/PA ndi Plastic/AL pa 121 ℃ kubweza kukukula.
Pepalali lidzayang'ana pa chitukuko chaposachedwa, malo owongolera panthawi yopanga komanso zomwe zidzachitike m'tsogolo.
1. Zatsopano zatsopano
Zikwama zobwezeretsa tsopano zagawidwa m'mitundu iwiri ya magawo, pulasitiki / pulasitiki ndi pulasitiki / aluminiyamu.Malingana ndi zofunikira za GB/T10004-2008, njira yobwezera imatchedwa theka la kutentha (100 ℃ - 121 ℃) ndi kutentha kwakukulu (121 ℃ - 145 ℃) miyeso iwiri.Pakali pano, zosungunulira-free laminating waphimba 121 ℃ ndi pansi 121 ℃ yotseketsa mankhwala.
Kupatula zida zodziwika bwino za PET, AL, PA, RCPP, zomwe zimagwiritsidwa ntchito pazigawo zitatu kapena zinayi zoyala, zida zina monga makanema owoneka bwino, obweza PVC amawonekera pamsika.Ngakhale palibe kupanga kwakukulu ndi kugwiritsa ntchito, zidazo zimafunikira nthawi yochulukirapo komanso kuyesedwa kochulukirapo kuti zigwiritsidwe ntchito kwambiri.
Pakadali pano, zomatira zathu za WD8262A/B zakhala zikuyenda bwino pagawo laling'ono PET/AL/PA/RCPP, lomwe lingafikire 121 ℃ kubweza.Pagawo lapulasitiki/pulasitiki PA/RCPP, zomatira zathu WD8166A/B zimakhala ndi ntchito zambiri komanso milandu yopangidwa.
Mfundo yovuta ya laminating yopanda zosungunulira, yosindikizidwa PET/Al tsopano yathetsedwa ndi WD8262A/B yathu.Tidagwirizana ndi ogulitsa zida zingapo, kuyezetsa ndikuwongolera nthawi zikwizikwi, ndipo pamapeto pake tidapanga WD8262A/B ndikuchita bwino.M'chigawo cha Hunan, makasitomala athu ali ndi chidwi chachikulu pa Aluminium retorting laminates, ndipo ndizosavuta kwa iwo kupanga mayeso.Pagawo losindikizidwa la PET/AL/RCPP, zigawo zonse zimakutidwa ndi WD8262A/B.Pamagulu osindikizidwa a PET/PA/AL/RCPP, PET/PA ndi AL/RCPP amagwiritsidwa ntchito WD8262A/B.Kulemera kwake kumakhala pafupifupi 1.8 - 2.5 g / m2, ndipo liwiro liri pafupi 100m / min - 120m / min.
mankhwala Kangda zosungunulira-free tsopano akwaniritsa patsogolo kwambiri pansi 128 ℃ ndi kusunga zovuta kwa 135 ℃ ngakhale 145 ℃ kutentha kutentha retorting mankhwala.Kukaniza mankhwala kumafufuzidwanso.
KUYESA KWA PERFORMANCE
| CHITSANZO | SUBSTRATES | KUPANDA MPHAMVU PAKATI PA 121℃ KUBWERETSA |
| WD8166A/B | PA/RCPP | 4-5N |
| WD8262A/B | AL/RCPP | 5-6N |
| WD8268A/B | AL/RCPP | 5-6N |

Zovuta:
Vuto lalikulu popanga matumba a aluminiyamu osanjikiza anayi ndikupeza kuphatikiza koyenera kwa zinthu zosiyanasiyana, kuphatikiza mafilimu, zomatira, inki ndi zosungunulira.Makamaka, kupanga PET/AL yosindikizidwa kwathunthu ndi gawo lakunja ili ndilovuta kwambiri.Tinkakumana ndi milandu iyi kuti, tikatenga zinthu kuchokera kwa makasitomala kupita ku labotale yathu ndikuyesa zinthu zonse kuphatikiza zida, palibe cholakwika chomwe chidapezeka.Komabe, tikaphatikiza zinthu zonse, magwiridwe antchito a laminates anali osakhutiritsa.Pokhapokha pamene matekinoloje onse, zipangizo, zipangizo zili pansi pa ulamuliro, gawo lapansi likhoza kupangidwa bwino.Fakitale ina ikhoza kupanga gawo lapansi izi sizikutanthauza kuti aliyense angathe kuchita bwino.
2. Malo owongolera panthawi yopanga
1) Kulemera kwake kumakhala pafupifupi 1.8 - 2.5 g / m2.
2) Chinyezi chozungulira
Chinyezi cham'chipinda chikuyenera kuwongolera pakati pa 40% -70%.Madzi omwe ali mumlengalenga adzachita nawo zomwe zomatira, chinyezi chachikulu chidzachepetsa kulemera kwa zomatira ndi kubweretsa zina zazing'ono, zomwe zimalimbikitsa ntchito ya retorting kukana.
3) Zokonda pa laminator
Malinga ndi makina osiyanasiyana, makonda oyenera monga kupsinjika, kupanikizika, chosakanizira ayenera kuyesedwa kuti apeze ntchito yoyenera ndikupanga laminates kukhala lathyathyathya.
4) Zofunikira zamakanema
Kuyenda bwino, mtengo wokwanira wa dyne, kuchepa ndi chinyezi ndi zina zonse ndizofunikira pakubweza laminating.
3. Zochitika zamtsogolo
Pakalipano, kugwiritsa ntchito zosungunulira zopanda zosungunulira kumayikidwa pamatumba osinthika, omwe ali ndi mpikisano woopsa.Pamfundo zaumwini, pali njira zitatu zopangira lamination wopanda zosungunulira.
Choyamba, chitsanzo chimodzi chokhala ndi ntchito zambiri.Chinthu chimodzi chimatha kupanga magawo ambiri opanga ma CD osinthika, omwe amatha kupulumutsa nthawi yambiri, zomatira komanso kuwonjezera mphamvu.
Kachiwiri, ntchito zapamwamba, zomwe zimapereka kukana kwakukulu kwa kutentha ndi mankhwala.
Pomaliza, chitetezo cha chakudya.Tsopano zosungunulira zopanda zosungunulira zimakhala ndi zoopsa zambiri kuposa zosungunulira-base lamination chifukwa zimakhala ndi zoletsa pazinthu zogwira ntchito kwambiri monga 135 ℃ retorting pochiches.
Koposa zonse, laminating yopanda zosungunulira ikukula mwachangu, matekinoloje atsopano ochulukirapo atuluka.M'tsogolomu, zosungunulira zopanda zosungunulira zimatha kutenga akaunti yayikulu pamsika wamapaketi osinthika ndi magawo ena.
