BOPA Yotsatizana Ndi Mbali Zonse Za Corona Yothandizidwa
OA2 ndiye mbali zonse ziwiri za corona zothandizidwa motsatizana za BOPA yokhala ndi zabwino zonse.Nthawi zambiri amagwiritsidwa ntchito ngati wosanjikiza wapakatikati komanso pamwamba ngati zokutira ndi kugwiritsa ntchito zitsulo.
| Mawonekedwe | Ubwino |
| ✦ Good flex crack resistance; ✦ Mphamvu zabwino ndi kukaniza / kukhudzidwa | ✦ Oyenera masanjidwe osiyanasiyana; ✦ Wokhoza kulongedza katundu wolemera, wakuthwa kapena wosasunthika wokhala ndi chitetezo chabwino kwambiri |
| ✦ Chotchinga chachikulu cha gasi; ✦ Ntchito zabwino kwambiri pa kutentha kwakukulu ndi kotsika; ✦ makulidwe osiyanasiyana; ✦ Kumveka bwino; ✦ Kusintha mwamakonda anu | ✦ Wonjezerani moyo wa alumali; ✦ Yoyenera chakudya chozizira ndi pasteurization / kuwira; ✦ Makulidwe opangidwa mogwirizana ndi zofunikira zamphamvu zosiyanasiyana - zotsika mtengo; ✦ Kumva bwino; ✦ Kukwaniritsa zomwe makasitomala amafuna |

OA2 itha kugwiritsidwa ntchito popanga makina osindikizira osinthika mkati mwamitundu itatu (kuphatikiza mitundu 3), kusindikiza m'lifupi.≤1cm ndipo popanda kufunikira kolembetsa kusindikiza, monga thumba lopanda kanthu, thumba la vacuum freeze, thumba lazinthu zam'madzi, ndi thumba la vacuum compression.Zomwe zili pansipa, thumba lamkati la mtedza (walnuts, mbewu za mpendadzuwa, ndi zina zotero) ndi thumba lamkati lazanyama (nkhuku yowotcha yaku Texas, steak, etc.), zotchingira zamagetsi, zoyika zamadzimadzi, monga vinyo, chakumwa, msuzi , thumba losungiramo mkaka wa m'mawere, thumba losungira madzi, supu ya nkhuku ya ginseng, thumba lamafuta, thumba la bokosi, chakudya chamlengalenga, thumba la nsomba zamoyo, nyama yozizira komanso yatsopano, nsomba zam'nyanja, halogen loko yotsekera mwatsopano, etc.
Kulowa Kwamtundu
Ndizosavuta kuchitika mu NY/PE(CPP).Mtundu wa mphete yowira imakhala yofiira komanso yofiirira panthawi yophika.Ngati wosanjikiza wakunja wasinthidwa kukhala PET mphete BOPP, ndiye kuti kulowa kwamtundu ndikosavuta kuchitika.
Zoyambitsa:
Kutentha ndi chinyezi (madzi) ndi zinthu ziwiri zofunika zomwe zimapangitsa kuti mitundu ilowe.
● Utomoni wa nayiloni ndi polima wa thermoplastic kuchokera ku semi-crystalline kupita ku amorphous.Kutentha kumawonjezeka, kusintha kwakukulu kwa dongosolo pakati pa mamolekyu, m'pamenenso kuthekera kwa kusamuka kwa pigment kumakulirakulira.
● Madzi a nayiloni sakanatha kupirira bwino, pamene akuwira, mamolekyu a madzi mu nayiloni mkati ndi kunja, akutsuka zigawo za pigment posindikiza inki.
● Mitundu ina imasungunuka m’madzi.
Malingaliro Ofananira:
✔ Gwiritsani ntchito inki ziwiri zamadzimadzi za polyurethane.
✔ Onjezani mankhwala ochiritsira pa inki yolowetsanso.
