Carbonated Beverage Bottle Qib PET Resin
Khoom Taw Qhia
Carbonated Beverage qib polyester chips yog TPA-based polyethylene terephthalic copolymer.Nws yog lub siab molecular hnyav polymer rau kev siv dav hauv kev tsim khoom ntim.Nws tuaj yeem siv rau hauv kev tsim cov ntim ntim rau cov dej haus carbonated xws li cola thiab 3-gallon, 5-gallon loj fwj.
Cov khoom lag luam muaj cov ntsiab lus tsis tshua muaj hlau hnyav, cov ntsiab lus qis ntawm acetaldehyde, xim zoo.viscosity ruaj khov thiab zoo rau kev ua haujlwm.Nrog rau daim ntawv qhia cov txheej txheem tshwj xeeb thiab cov cuab yeej siv ntau lawm, ntxiv dag zog rau cov txheej txheem tswj thiab kev tswj kom zoo, cov khoom lag luam nrog cov cuab yeej sib cais zoo heev yog siv los tiv thaiv cov pa roj carbon dioxide los ntawm kev xau, zoo hauv kev ua haujlwm siab, tsis tshua muaj kub ua, dav dav hauv kev ua, zoo heev hauv pob tshab, siab nyob rau hauv cov khoom tiav lawm thiab tuaj yeem tiv thaiv lub raj mis los ntawm kev tawg rau cov dej haus carbonated uas nyob rau hauv lub sijhawm cia thiab nyob rau hauv siab.

Hom kev ua haujlwm
Kev ziab yog tsim nyog ua ntej cov txheej txheem yaj los tiv thaiv cov resin los ntawm hydrolysis.Tej yam kev mob ziab yog huab cua kub ntawm 165-185 ° C, 4-6 teev nyob rau lub sij hawm, dew point kub hauv qab -40 * C.
Qhov ntsuas kub zoo li ntawm 280-298 ° C.
