Iitshiphusi zepolyester CZ-333
Uhlobo
"JADE" Brand , homopolyester.
Inkcazo
"I-JADE" I-Brand homopolyester "i-CZ-333" yeetshiphusi ze-polyester zebanga lebhotile zineziqulatho eziphantsi zetsimbi enzima, umxholo ophantsi we-acetaldehyde, ixabiso lombala olungileyo, i-viscosity ezinzileyo kwaye ilungele ukusetyenzwa. Kunye inkqubo iresiphi eyodwa kunye nobuchwepheshe imveliso phambili, imveliso, xa thermoformed kwi SIPA, SIDEL, ASB njl koomatshini bokwenza ibhotile eziphambili phantsi kweemeko jikelele, inezinga eliphezulu tropism, crystallinity ezinzile kunye fluidity elungileyo kunye izinga eliphantsi uxinzelelo-ukukhululwa kwi. ibhotile yonke, isantya se-thermal contraction esizinzile kunye nesantya esiphezulu semveliso egqityiweyo ekwenzeni iibhotile, inokwanelisa imfuno yokuba ibhotile malunga ne-90 ° C kwaye ikhusele iziphuzo ukusuka kwi-discoloration okanye i-oxidization kwixesha lokugcina kunye nokuthintela ukuguqulwa kweebhotile.
Usetyenziso
ngokukhethekileyo esetyenziselwa iibhotile zokuzalisa shushu ngokweziselo zeti、iziselo zejusi yeziqhamo kunye nezinye iziselo eziphakathi zifuna ukuba ibhotile eshushu yokuvala inzala.
Iimeko eziqhelekileyo zokuqhuba
Ukomisa kuyimfuneko ngaphambi kokuba kuqhutywe ukunyibilika ukukhusela i-resin kwi-hydrolysis. Iimeko eziqhelekileyo zokomisa zibubushushu bomoya obuyi-165-185 ° C, iiyure ezingama-4-6 zokuhlala, ubushushu bombethe bungaphantsi -40 ℃. Ubushushu obuqhelekileyo bombhobho malunga ne-285-298 ° C.
