Iitshiphusi zePolyester CZ-333
Uhlobo
"JADE" Brand , homopolyester.
Inkcazo
"JADE" Brand homopolyester "CZ-333" iitshiphusi zepolyester zenqanaba lebhotile zinomxholo wetsimbi enzima, umxholo ophantsi we-acetaldehyde, ixabiso lombala olungileyo, i-viscosity ezinzileyo kwaye ilungele ukusetyenzwa. Ngenkqubo eyodwa iresiphi kunye nobuchwepheshe bemveliso ephucukileyo, imveliso, xa isenziwa thermoformed kwi-SIPA, SIDEL, ASB njl njl. kunye ne-fluidity enhle kunye nesantya esiphantsi soxinzelelo-ukukhululwa kwibhotile, isantya esizinzile se-thermal contraction kunye nesantya esiphezulu semveliso egqityiweyo ekwenzeni iibhotile, inokwanelisa imfuno yokuba ibhotile malunga ne-90 ° C kunye nokukhusela iziphuzo ezisuka kwi-discoloration okanye i-oxidization kwixesha lokugcina kunye nokuthintela ukuguqulwa kweebhotile.
Usetyenziso
ngokukodwa ezisetyenziselwa 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.
