Malinga ndi zida zomwe zimagwiritsidwa ntchito popanga filimu ya poliyesitala komanso kupanga gulu.

Malinga ndi zinthu zosiyanasiyana zopangira ndi zojambula zomwe zimagwiritsidwa ntchito popanga filimu ya polyester zitha kugawidwa m'mitundu iwiri yotsatirayi.

1. Filimu ya Bidirectional Stretch Polyester (BOPET)

Kanema wa BOPET wa General BOPET ndikugwiritsa ntchito zinthu zowala (zomwe zimadziwikanso kuti zida zazikulu zowala, ndiye kuti, zopangira poliyesitala chip titaniyamu wowutsa mudyo zili 0.1%, mutatha kuyanika, kusungunula, kutulutsa, kuponyera ndi kutambasula molunjika komanso kopingasa kwa filimu yapamwamba kwambiri. , yogwiritsidwa ntchito kwambiri).Kanema wa BOPET ali ndi mawonekedwe amphamvu kwambiri, kusasunthika kwabwino, kuwonekera komanso kuwala kwambiri.Zopanda fungo, zosakoma, zopanda mtundu, zopanda poizoni, mphamvu zapadera ndi zolimba;Mphamvu yake yokhazikika ndi 3 nthawi ya filimu ya PC, filimu ya nayiloni, mphamvu ya mphamvu ndi 3 ku 5 nthawi ya filimu ya BOPP, imakhala ndi kukana kovala bwino, kukana kupindika, kukana kwa pinhole ndi kukana misozi;Kutsika kwamafuta kumakhala kochepa kwambiri, pa 120 ℃, kokha 1.25% shrinkage pambuyo pa 15min;Ili ndi katundu wabwino antistatic, zosavuta vacuum aluminization, ndipo akhoza TACHIMATA ndi PVDC kusintha kutentha wake kusindikiza, chotchinga katundu ndi kusindikiza adhesion;BOPET ilinso ndi kukana kwabwino kwa kutentha, kukana kuphika bwino, kukana kuzizira kozizira, kukana mafuta abwino komanso kukana mankhwala.BOPET filimu kuwonjezera nitrobenzene, chloroform, benzyl mowa, mankhwala ambiri sangathe kupasuka.Komabe, BOPET idzaphwanyidwa ndi alkali yamphamvu, ndipo iyenera kutsatiridwa ndikugwiritsa ntchito.Kanema wa BOPET ali ndi mayamwidwe amadzi otsika, kukana madzi abwino, ndipo ndi oyenera kunyamula zakudya zomwe zili ndi madzi ambiri.

2. Unidirectional Stretch Polyester Film (CPET)

General CPET filimu ndi ntchito theka-matting zakuthupi (yaiwisi poliyesitala tchipisi kuwonjezera titaniyamu woipa), pambuyo kuyanika, kusungunuka, extrusion, kuponyera ndi kotalika kutambasula filimu, otsika kalasi ndi mtengo mu filimu poliyesitala, makamaka ntchito piritsi mankhwala. kuyika.Chifukwa chogwiritsa ntchito pang'ono, opanga kupanga zochepa zazikulu, zomwe zimawerengera pafupifupi 5% ya gawo la filimu ya poliyesitala, mabizinesi aku China nawonso amatumizidwa kunja, makulidwe a 150μm.
