IBottle ezaliswe shushu kwiBanga le-PET Resin Umfanekiso ofakiweyo
  • IBottle ezaliswe ngokushushu kwiBanga le-PET Resin

IBottle ezaliswe ngokushushu kwiBanga le-PET Resin


  • Iimpawu kunye nokusebenza:Ine-orientation ephezulu ekhuthazwayo, i-crystallinity ezinzileyo, ukulula ukulawula ukuhanjiswa kobunzima bodonga, ukukhutshwa koxinzelelo oluphantsi-ireyithi eseleyo yebhotile yonke, kunye ne-stable shrinkage ye-thermal ekuvuthelweni kwebhotile.Ukongeza, ziichips ezinikezelweyo zeebhotile ezizaliswe kushushu eziphuhliswe kwaye zenzelwe isiselo esiphakathi esifuna unyango lokuzalisa inzala eshushu.
  • Imiba yesicelo:Iibhotile zesiselo seti, ijusi kunye nezinye iziselo zemidiya ezifuna unyango lokuvala inzala eshushu.
  • Iimathiriyeli ekrwada eziphambili:PTA, MEG, IPA

    Iithegi zeMveliso

    Intshayelelo yeMveliso

    Iitshiphusi zepolyester zebanga elishushu ezizaliswe zibhotile ziye zaphuhliswa kwaye zaveliswa ngokukodwa kwiibhotile zokuzalisa ezishushu ngokweziselo zeti, iziselo zejusi yeziqhamo kunye nezinye iziselo zodidi oluphakathi zifuna ukuba ibhotile eshushu yokuvala inzala.

    /isicelo/

    Uphawu lwemveliso lubonisa umxholo wentsimbi enzima ephantsi, 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 oluzinzileyo kunye fluidity elungileyo kunye izinga eliphantsi uxinzelelo-ukukhululwa kwi. ibhotile yonke, isantya esizinzile se-thermal contraction kunye nesantya esiphezulu semveliso egqityiweyo ekwenzeni iibhotile, inokwanelisa imfuno yokuba ibhotile malunga ne-90 ° C kwaye ikhusele iziphuzo ekuguqulweni kombala okanye i-oxidization ngexesha lokugcina kunye nokuthintela ukuguqulwa kweebhotile.

    Iimeko zoLungiselelo oluqhelekileyo

    Ukomisa kuyimfuneko ngaphambi kokuba kuqhutywe ukunyibilika ukukhusela i-resin kwi-hydrolysis.Iimeko zokumisa eziqhelekileyo zibushushu bomoya be-165-185 ° C, iiyure ezingama-4-6 zokuhlala, ubushushu bombethe bungaphantsi -40 0C.

    Ubushushu obuqhelekileyo bombhobho malunga ne-285-298 ° C.
