Iindaba

I-resin matrix ye-thermoplastic ibandakanya iplasitiki yobunjineli ngokubanzi, kunye ne-PPS ngummeli oqhelekileyo weplasitiki yobunjineli obukhethekileyo, owaziwayo njenge "igolide yeplastiki". Inzuzo yentsebenzo ibandakanya le miba ilandelayo: Ukumelana nobushushu obuhle, iipropathi zoomatshini, ukunganyangeki, kunye nokufakelwa kwe-IL94 V-0. Kungenxa yokuba i-PPs inezibonelelo zentsebenzo ezingentla, kwaye zithelekiswa nezinye iiplasitiki ze-thertolic zobunjineli, ineempawu zokusebenza ngokulula kunye neendleko eziphantsi, ngenxa yoko iba yi-terix efanelekileyo yokufumana izinto ezihlanganisiweyo.

Izixhobo ze-PPS kunye neglasi ye-fiber ye-fiber (SGF) inezibonelelo zamandla aphezulu, ukuxhathisa ubushushu, ilangatye, ukulungiswa ngokulula, iindleko eziphantsi, njl.
I-PPS yandiswa i-fiber ye-fiber ye-fiber (i-LGF) inezibonelelo zokungaphezulu, ifayili ephantsi, ukuchasana nemveliso yemveliso, impompo yamachiza, izixhobo zokupholisa, izixhobo zokusebenza, izixhobo zokusebenza, izixhobo zokusebenza, njl.

Ke yintoni umahluko othile kwipropathi ye-fiber yefibre yeglasi emfutshane (SGF) kunye neglasi ye-fiber yeglasi (LGF) eyomeleze iindidi zePPS?

Ipropathi ebanzi ye-PPS / SGF (i-SGF (i-Sfutshane yeFire) kunye ne-PPS / LGF (i-LGF (i-LGF (i-fiber ende) ithelekiswa. Isizathu sokuba inyibilikisiwe inkqubo yokungangqinelani isetyenziswa kulungiselelo lwegran ye-screw kukuba ukubongwa kwe-fiber tundle ifezekisiwe kubumba bobubi, kwaye i-fiber ayilonakalanga. Okokugqibela, ngokubhekisele ekuthetheni idatha yepropathi yoomatshini kwezi zimbini, kunokubanika inkxaso yezobuchwephesha kwisehlo sesayensi kunye nabasebenzi benzululwazi xa bekhetha izixhobo.

Uhlalutyo lwepropathi yoomatshini
Ukuqiniswa kwe-fibers yongezwa kwi-resn matrix inokwenza i-skeleton exhasayo. Xa izinto ezihlanganisiweyo ziphantsi kwamandla angaphandle, ukunyanzeliswa kweentsinga kunokuyibonisa ngokufanelekileyo indima yangaphandle; Kwangelo xesha, inokufumana amandla ngokuqhekeka, ukungcungcutheka, njl njl.

Xa umxholo we-fiber ye-fiber fiber, iintsinga ezininzi zeglasi kwizinto ezihlanganisiweyo ziphantsi kwamandla angaphandle. Kwangelo xesha, ngenxa yokwanda kwenani leentsinga zeglasi, iMatrix ye-Ressin phakathi kweglasi yeglasi iba mncinci, okukhululekileyo ngakumbi kulwakhiwo lwefayiwe ye-fiber; Ke ngoko, ukwanda kwesiqulatho se-fiber senza ukuba izinto ezihlanganisiweyo zidlulise uxinzelelo ngakumbi kwi-resin kwi-fiber yeglasi engaphandle komthwalo ongaphandle, ophucula iipropathi ezinobungqingiwa.
Iipropathi ezinobungqiwa kunye nezohlobo ze-PPS / ze-LGF eziphezulu ziphezulu kunezo ze-PPs / SGF. Xa iqhezu elinzima lefayibha yeglasi ngama-30%, amandla e-thobile ye-PPPS / SGF kunye ne-PPS / i-LGF i-110NPA kunye ne-122MPA, ngokulandelelana; Amandla aguqukayo ayi-175MPA ne-208MPA, ngokulandelelana; Imodyuli ye-elastic ye-elastic yi-8GPA ne-9GPA, ngokwahlukeneyo.
Amandla ozithobe, amandla atshisiweyo kunye ne-Elastic ye-PRPS / i-LGF inyuswe nge-11.0%, 18.9% kunye ne-11.3%, ngokuthelekisa i-PPS / SGF. Ubude bemigangatho yokugcina i-fiber yeglasi kwi-PPS / ye-LGF yeNcitho iphezulu. Phantsi komxholo wefibre ye-fiber ofanayo, isixhobo esihlanganayo sinenkcaso yomthwalo kunye neepropathi ezingcono zoomatshini.
