Ukushisisa kabusha kwe-CSD PET Resin
Isingeniso Somkhiqizo
I-Fast Reheated CSD PET Resin, elungele ukusebenzisa izinyathelo ezimbili zokufutha amabhodlela okupakisha iziphuzo ezine-carbonated futhi isetshenziswe kabanzi ngabakhiqizi eNingizimu naseNyakatho Melika, eYurophu nase-Coca-cola China.
Ngesikhathi senqubo yokukhiqiza, lolu hlobo lwama-chips lunezici eziyinhloko zokumuncwa okusheshayo kokushisa, ukwehlisa ukusetshenziswa kwamandla, ukwandisa isivinini sokushaywa nokuphumayo, kanye nokwenza ngcono ukusebenza kahle.Ngenxa yeresiphi yenqubo eyingqayizivele kanye nobuchwepheshe bokukhiqiza obuphambili, lo mkhiqizo omusha unezakhiwo ezinhle kakhulu futhi ushiya izindinganiso zokusebenza eziyinhloko njengama-chips ebanga lebhodlela le-Carbonated ayisisekelo engashintshiwe.Umbala walolu hlobo lwama-chips ufiphele kancane, kodwa imikhiqizo yokugcina ihle kakhulu ekukhanyeni.

Izimo Ezijwayelekile Zokucubungula
Ukomisa kuyadingeka ngaphambi kokucubungula ukuncibilika ukuvimbela i-resin kusuka ku-hydrolysis.Izimo ezijwayelekile zokomisa ukushisa komoya okungu-165-185 ℃, isikhathi sokuhlala samahora angu-4-6, izinga lokushisa lamazolo elingaphansi -40 ℃.
Izinga lokushisa lomphongolo elijwayelekile lingaba ngu-280-298 ℃.
