Kugwiritsa ntchito
Monga mtundu umodzi wa zozimitsa moto wochezeka ndi chilengedwe, zitha kugwiritsidwa ntchito kusinthidwa kosatha kwamoto wochepetsetsa wa poliyesitala, ndipo kupindika kwa poliyesitala wamoto kumakhala kofanana ndi PET, motero kumatha kugwiritsidwa ntchito mumitundu yonse ya makina ozungulira, okhala ndi mawonekedwe abwino kwambiri amatenthedwe. kukhazikika, osawola panthawi yozungulira komanso osanunkhiza. Itha kugwiritsidwa ntchito m'magawo onse ogwiritsira ntchito PET kuti apititse patsogolo mphamvu ya antistatic ya polyester. Mlingo wa copolymerization wa PTA ndi EG ndi 2.5 ~ 4.5%, phosphorous assay wa flame retarding poliyesitala pepala ndi 0.35-0.60%, ndi LOI wa flame retarding mankhwala ndi 30-36%.
