Daim Ntawv Thov:
Ua ib hom tshuaj tua hluav taws uas tsis ua rau ib puag ncig puas tsuaj, nws siv tau rau kev hloov kho polyester uas tiv thaiv hluav taws mus tas li, thiab qhov ua tau ntawm polyester uas tiv thaiv hluav taws zoo ib yam li PET, yog li nws siv tau rau txhua yam kev sib hloov, nrog rau kev ruaj khov zoo heev, tsis muaj decompound thaum sib hloov thiab tsis muaj ntxhiab. Nws siv tau rau txhua qhov chaw siv PET los txhim kho lub peev xwm tiv thaiv hluav taws xob ntawm polyester. Qhov ntau npaum li cas rau kev sib xyaw ua ke ntawm PTA thiab EG yog 2.5 ~ 4.5%, qhov kev ntsuas phosphorus ntawm cov ntawv polyester uas tiv thaiv hluav taws yog 0.35-0.60%, thiab LOI ntawm cov khoom tiv thaiv hluav taws yog 30 ~ 36%.
