Isicelo
Njengohlobo olulodwa lwe-fire retardant evumelana nemvelo, ingasetshenziswa ukuguqulwa okungapheli kokubuyisela amalangabi kwe-polyester, futhi ukujikeleza kwe-polyester ebambezela ilangabi kufana ne-PET, ngaleyo ndlela ingasetshenziswa kuzo zonke izinhlobo zesistimu yokuphotha, enezici ezifana ne-thermal ehle kakhulu. ukuzinza, akukho ukubola ngesikhathi sokuphotha futhi akukho phunga.Ingasetshenziswa kuzo zonke izinkambu zohlelo lwe-PET ukuthuthukisa umthamo we-antistatic we-polyester.Umthamo we-copolymerization ye-PTA ne-EG ngu-2.5 ~ 4.5%, i-phosphorus assay yeshidi le-polyester elibambezeleka ngamalangabi ngu-0.35-0.60%, kanti i-LOI yemikhiqizo ebambezela ilangabi ingu-30~36%.
Iphakheji
25kg isigubhu sekhadibhodi noma isikhwama sepulasitiki esifakwe umugqa wesikhwama esilukiwe
Isitoreji
Gcina endaweni epholile, eyomile, enomoya omuhle, kude ne-oxidizer enamandla.
