Daim ntawv thov:
Raws li ib yam ntawm ib puag ncig-phooj ywg hluav taws kub retardant, nws tuaj yeem siv cov nplaim hluav taws kub nyhiab hloov pauv ntawm polyester, thiab cov nplaim hluav taws kub nyhiab polyester zoo ib yam li PET, yog li nws tuaj yeem siv rau txhua yam kev sib tw, nrog cov yam ntxwv zoo li thermal zoo heev. stability, tsis muaj decompound thaum spinning thiab tsis hnov tsw. Nws tuaj yeem siv tau rau hauv txhua daim ntawv thov ntawm PET txhawm rau txhim kho lub peev xwm antistatic ntawm polyester. Qhov ntau npaum li cas rau copolymerization ntawm PTA thiab EG yog 2.5 ~ 4.5%, phosphorus assay ntawm nplaim retarding polyester ntawv yog 0.35-0.60%, thiab LOI ntawm nplaim retarding khoom yog 30 ~ 36%.
