Polyester chips CZ-302
Uhlobo
"JADE" Brand, Copolyester.
Incazelo
I-“JADE” Brand Copolyester “CZ-302″ ye-polyester grade grade chips inokuqukethwe okuphansi kwensimbi esindayo, okuqukethwe okuphansi kwe-acetaldehyde, inani lombala elihle, i-viscosity ezinzile. Ngeresiphi yenqubo eyingqayizivele kanye nobuchwepheshe bokukhiqiza obuthuthukisiwe, umkhiqizo unezici ezinhle kakhulu zokucubungula, izinga lokushisa eliphansi lokucubungula, ububanzi bokucubungula, ukukhanya okuhle kakhulu kanye nezinga eliphezulu lomkhiqizo oqediwe. Ekwenzeni amabhodlela, umkhiqizo unokuwohloka okuncane kanye nokuqukethwe okuphansi kwe-acetaldehyde. Ngenkathi iqinisekisa ukuphepha kanye nenhlanzeko, ingagcina ngempumelelo ukunambitheka okuyingqayizivele kwamanzi ahlanzekile, amanzi amaminerali namanzi acwecwe.
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.
