Kusindikiza Mwamakonda Pang'onopang'ono Kupaka Makanema Apulasitiki Ochapira Zotsukira Sachet Pamanja Sopo Wochapira Ufa Kulongedza Mafilimu

Zida zotsuka filimu yotsuka ufa (filimu yosungunuka m'madzi) nthawi zambiri imakhala PET / PE ndi PET / NY / PE, ndipo imathanso kuphatikizidwa ndi zina zowonongeka kapena zogwira ntchito. Pakatikati pa kapangidwe kazinthu izi ndikuteteza chilengedwe, chitetezo ndi magwiridwe antchito. Zotsatirazi ndizopindulitsa zake zenizeni:

1. PET/PE wochapira ufa wopukuta filimu Wosanjikiza wakunja: PET (polyethylene terephthalate)

Amapereka mphamvu zamakina apamwamba, kukana kwa puncture ndi kusindikiza. Oyenera makina onyamula othamanga kwambiri. Ndipo mawonekedwe a PET ndi oyenera kusindikiza molondola kwambiri, zomwe zimapangitsa kuti zinthu ziwoneke bwino.

Wosanjikiza wamkati: PE (polyethylene) Amapereka kusindikiza kutentha, kusinthasintha komanso kukana chinyezi. Chosanjikiza cha PE chikhoza kusindikizidwa kutentha kutentha pang'ono kuti muwonjezere bwino ma phukusi. Imatchinga nthunzi wamadzi ndikuletsa ufa wochapira kuti usanyowe ndi kusungunuka.

2. PET/NY/PE filimu yochapa ufa wochapira Wosanjikiza wakunja: PET (polyethylene terephthalate)

Amapereka kusindikiza ndi mphamvu zamakina.

Zosanjikiza zapakati: NY (nayiloni, PA) Zowonjezera zotchinga (oxygen, fungo). Wosanjikiza wa NY amatha kuletsa mpweya, chinyezi ndi fungo, kukulitsa moyo wa alumali wa chotsukira. Imakhala ndi kukana kwambiri pobowola, yosamva kutulutsa komanso kuvala kwamayendedwe, ndipo ndiyoyenera zotsukira zomwe zimagwira ntchito kwambiri: monga zotsukira zomwe zimakhala ndi ma enzymes okonzekera ndi zonunkhira, kuteteza kuti zosakanizazo zisagwire ntchito.

Mkati wosanjikiza: PE (polyethylene) Amapereka kutentha kusindikiza ndi kufewa. Zida zotsuka filimu yotsuka ufa (monga PVA) zimakwaniritsa zofunikira za zinthu zamakono zotsuka pogwiritsa ntchito mawonekedwe a chitetezo ndi osakhala kawopsedwe, chotchinga chogwira ntchito kwambiri, kamangidwe katsopano, ndi zina zotero, kuthetsa zowawa zamapaketi achikhalidwe, ndipo ndizoyenera makamaka pamsika wogula wogula womwe umayang'ana pa chitukuko chokhazikika komanso chosavuta.
