Isicelo:
Njengenye yeendlela zokuthintela umlilo ezinobuhlobo nokusingqongileyo, ingasetyenziswa njengendlela yokuguqula i-polyester egcina ilangatye lihle, kwaye ukuguquguquka kwe-polyester egcina ilangatye lihle kufana ne-PET, ngoko ke ingasetyenziswa kuzo zonke iintlobo zenkqubo yokujikeleza, ineempawu ezifana nokuzinza okuhle kobushushu, akukho kuqhekeka ngexesha lokujikeleza kwaye akukho vumba. Ingasetyenziswa kuzo zonke iindawo zokusetyenziswa kwe-PET ukuphucula amandla e-polyester amelana ne-static. Umlinganiselo we-copolymerization ye-PTA kunye ne-EG yi-2.5 ~ 4.5%, uvavanyo lwe-phosphorus lwephepha le-polyester egcina ilangatye yi-0.35-0.60%, kwaye i-LOI yeemveliso ezigcina ilangatye yi-30 ~ 36%.
Iphakheji:
Idrama yekhadibhodi engama-25kg okanye ibhegi yeplastiki ephothiweyo
