Amacupa Yamazi Icyiciro PET Resin （PET）
Kumenyekanisha ibicuruzwa
Amacupa yo mu cyiciro cya polyester chip arakenewe mugukora amacupa yo gupakira kumazi meza water amazi yumutungo kamere water amazi yatoboye, amazi yo kunywa 、 uburyohe hamwe na bombo, icupa rya maquillage nibikoresho bya PET nibindi.
Ikirangantego cyibicuruzwa biranga ibyuma biremereye biremereye, ibirimo bike bya acetaldehyde value agaciro keza keza 、 ubwiza buhamye.Hamwe nibikorwa bidasanzwe hamwe nubuhanga buhanitse bwo gukora, ibicuruzwa bifite ibintu byiza byo gutunganya, ubushyuhe buke bwo gutunganya, urugero runini mugutunganya, gukorera mu mucyo no hejuru mubicuruzwa byarangiye.Mugukora amacupa, ibicuruzwa bifite kwangirika gake hamwe nibirimo bike bya acetaldehyde.Nubwo kubungabunga umutekano n’isuku, birashobora kugumana uburyohe bwihariye bwamazi meza asukuye water amazi yubutare namazi meza.

Uburyo busanzwe bwo gutunganya
Kuma birakenewe mbere yo gutunganya gushonga kugirango wirinde ibisigazwa bya hydrolysis.Ibisanzwe byumye ni ubushyuhe bwikirere bwa 160-180 ° C, amasaha 4-6 yo gutura, ubushyuhe bwikime munsi -40 * C.
Ubushyuhe busanzwe bwa barriel hafi 275-293 ° C.
