Isicelo
Njengolunye uhlobo lwesithako somlilo esivikela imvelo, singasetshenziswa ukuguqulwa kwe-polyester okuhlala njalo okubambezela ilangabi, futhi ukuqina kwe-polyester ebambezela ilangabi kufana ne-PET, ngakho-ke singasetshenziswa kuzo zonke izinhlobo zesistimu yokuphotha, ngezici ezifana nokuzinza okuhle kakhulu kokushisa, ukungaboli ngesikhathi sokuphotha kanye nokunganuki. Singasetshenziswa kuzo zonke izinkambu zokusetshenziswa kwe-PET ukuthuthukisa amandla e-polyester amelana ne-static. Umthamo we-copolymerization we-PTA kanye ne-EG ungu-2.5~4.5%, ukuhlolwa kwe-phosphorus kweshidi le-polyester elibambezela ilangabi lingu-0.35-0.60%, kanti i-LOI yemikhiqizo ebambezela ilangabi ingu-30~36%.
Iphakheji
Isikhwama sekhadibhodi esingu-25kg noma isikhwama sepulasitiki esilukiwe esinophahla
Isitoreji
Gcina endaweni epholile, eyomile, enomoya omuhle, kude ne-oxidizer enamandla.
