Amacupa ashyushye yuzuye Icupa rya PET Resin
Kumenyekanisha ibicuruzwa
Amacupa ashyushye yuzuye ya polyester chip yatunganijwe kandi yakozwe cyane cyane kumacupa yuzuye ashyushye ukurikije ibyo binyobwa byicyayi drink ibinyobwa-umutobe wimbuto nibindi binyobwa byubwoko buciriritse bisaba kuba icupa rishyushye kugirango sterilisation.
Ikirangantego cyibicuruzwa biranga ibyuma biremereye biremereye, ibirimo bike bya acetaldehyde value agaciro keza k'ibara vis Ubwiza buhamye kandi bwiza bwo gutunganya.Hamwe nimikorere idasanzwe hamwe nubuhanga buhanitse bwo gukora, ibicuruzwa, iyo bishyizwe muri SIPA 、 SIDEL 、 ASB nibindi imashini zikora amacupa mubihe rusange, ifite umuvuduko mwinshi wa tropisme, kristu ihamye hamwe namazi meza hamwe nigipimo gito cyo kurekura ibibazo muri icupa ryose, igipimo cyogukwirakwiza ubushyuhe bwumuriro nigipimo cyinshi cyibicuruzwa byarangiye mugukora amacupa, birashobora guhaza icyifuzo cyo guterwa amacupa kuri 90 ° C kandi bikarinda ibinyobwa guhinduka amabara cyangwa okiside mugihe cyo kubika kandi bikarinda ihinduka ryamacupa.

Uburyo busanzwe bwo gutunganya
Kuma birakenewe mbere yo gutunganya gushonga kugirango wirinde ibisigazwa bya hydrolysis.Ibihe byumye ni ubushyuhe bwikirere bwa 165-185 ° C, amasaha 4-6 yo gutura, ubushyuhe bwikime munsi -40 0C.
Ubushyuhe busanzwe bwa barriel hafi 285-298 ° C.
