Polyester chips CZ-302
Uhlobo
"JADE" Brand, Copolyester.
Incazelo
I-“JADE” Brand Copolyester “CZ-302″ ye-polyester yebanga lebhodlela chips inokuqukethwe okuphansi kwensimbi esindayo, okuqukethwe okuphansi kwe-acetaldehyde, inani lombala elihle, i-viscosity ezinzile. Ngeresiphi yenqubo eyingqayizivele kanye nobuchwepheshe bokukhiqiza obuthuthukile, umkhiqizo unezici ezinhle kakhulu zokucubungula, izinga lokushisa eliphansi lokucubungula, ububanzi obubanzi bokucutshungulwa, ukucaca okuhle kakhulu kanye nokwehla okuphezulu kokuqukethwe kwebhodlela okuqediwe, ekwenzeni izinga lomkhiqizo omncane oqediwe. I-acetaldehyde, ngenkathi iqinisekisa ukuphepha nenhlanzeko, ingagcina ukunambitheka okuyingqayizivele kwamanzi ahlanzekile, amanzi amaminerali kanye namanzi acwengekile.
Izinhlelo zokusebenza
Alungele ukwenza amabhodlela okupakisha amanzi ahlanzekile, amanzi amaminerali emvelo, amanzi acwecwe, amanzi okuphuza, iziqukathi zokunambitheka namaswidi, ibhodlela lezimonyo kanye nezinto ze-PET sheet.
Izimo ezijwayelekile zokucubungula
Ukomisa kuyadingeka ngaphambi kokucubungula ukuncibilika ukuvimbela i-resin kusuka ku-hydrolysis. Izimo ezijwayelekile zokomisa ukushisa komoya okungu-160-180 ° C, isikhathi sokuhlala samahora angu-4-6, izinga lokushisa lamazolo lingaphansi -40 ℃. Izinga lokushisa lomphongolo elijwayelekile lingaba ngu-275-293°C.
