Kugwiritsa ntchito
Monga mtundu umodzi wa choletsa moto chomwe sichiwononga chilengedwe, chingagwiritsidwe ntchito posintha polyester yoletsa moto nthawi zonse, ndipo kusinthasintha kwa polyester yoletsa moto kuli kofanana ndi PET, motero chingagwiritsidwe ntchito m'njira zosiyanasiyana zozungulira, chokhala ndi mawonekedwe abwino kwambiri a kutentha, chosawonongeka pakuzungulira komanso chopanda fungo. Chingagwiritsidwe ntchito m'magawo onse ogwiritsira ntchito PET kuti chiwongolere mphamvu ya polyester yoletsa moto. Mlingo wa copolymerization wa PTA ndi EG ndi 2.5 ~ 4.5%, phosphorous assay ya pepala la polyester yoletsa moto ndi 0.35-0.60%, ndipo LOI ya zinthu zoletsa moto ndi 30 ~ 36%.
Phukusi

Malo Osungirako
Sungani pamalo ozizira, ouma, komanso opumira bwino, kutali ndi chotenthetsera champhamvu.
