Ibinyobwa bya Carbone Icupa Icyiciro PET Resin
Kumenyekanisha ibicuruzwa
Ibinyobwa bya karubone ya polyester chip ni TPA ishingiye kuri polyethylene terephthalic copolymer.Nuburemere buke bwa polymer kugirango bukoreshwe muri rusange.Irashobora gukoreshwa mugukora amacupa yo gupakira kubinyobwa byoroshye bya karubone nka cola na litiro 3, amacupa manini 5.
Ikirangantego cyibicuruzwa biranga ibyuma biremereye biremereye, ibirimo bike bya acetaldehyde, agaciro keza keza.Ubwiza buhamye kandi bwiza bwo gutunganya.Hamwe nibikorwa bidasanzwe hamwe nubuhanga buhanitse bwo gukora, gushimangira kugenzura no gucunga neza, ibicuruzwa bifite umutungo mwiza wo kwigunga bigira akamaro mukurinda dioxyde de carbone kumeneka, byiza mukurwanya umuvuduko, gutunganya ubushyuhe buke, murwego runini mugutunganya, byiza muri gukorera mu mucyo, hejuru yikigereranyo cyibicuruzwa byarangiye kandi birashobora gukumira neza amacupa kumeneka kubinyobwa bya karubone biri mugihe cyo guhunika kandi munsi yigitutu.

Uburyo busanzwe bwo gutunganya
Kuma birakenewe mbere yo gutunganya gushonga kugirango wirinde ibisigazwa bya hydrolysis.Ibisanzwe byumye ni ubushyuhe bwikirere bwa 165-185 ° C, amasaha 4-6 yo gutura, ubushyuhe bwikime munsi -40 * C.
Ubushyuhe bwa barriel hafi 280-298 ° C.
