iindaba

I-resin matrix ye-thermoplastic composites ibandakanya iiplastiki zobunjineli eziqhelekileyo kunye nezikhethekileyo, kwaye i-PPS ngummeli oqhelekileyo weeplastiki ezikhethekileyo zobunjineli, ezaziwa ngokuba "yigolide yeplastiki".Iinzuzo zokusebenza ziquka le miba ilandelayo: ukumelana nobushushu obugqwesileyo, iipropati ezilungileyo zemishini, ukuxhathisa ukubola, kunye nokuzitshisa ukuya kwinqanaba le-UL94 V-0.Ngenxa yokuba i-PPS inezibonelelo zokusebenza ezingentla, kwaye xa ithelekiswa nezinye iiplastiki zobunjineli be-thermoplastic ezisebenza kakhulu, ineempawu zokusetyenzwa lula kunye neendleko eziphantsi, ngoko iye yaba yeyona matrix yeresin egqwesileyo yokwenza izinto ezidibeneyo.

I-PPS kunye ne-fiber yeglasi emfutshane (SGF) izinto ezidibeneyo zineenzuzo zamandla aphezulu, ukumelana nobushushu obuphezulu, i-flame retardant, ukusetyenzwa lula, ixabiso eliphantsi, njl.
I-PPS i-fiber yeglasi eyandisiweyo (LGF) izinto ezidibeneyo zineenzuzo zokuqina okuphezulu, i-warpage ephantsi, ukuxhathisa ukukhathala, ukubonakala kwemveliso enhle, njl. ii-impellers kunye neeShell, iinxalenye zesixhobo sekhaya, njl.

Ngoko ke zeziphi iiyantlukwano ezithile kwiipropati zefiber yeglasi emfutshane (SGF) kunye nefiber yeglasi ende (LGF) eyomeleziweyo yePPS imidibaniso?

Iipropati ezibanzi zePPS/SGF (ifiber yeglasi emfutshane) iicomposites kunye nePPS/LGF (ifiber yeglasi ende) yathelekiswa.Isizathu sokuba i-melt impregnation inkqubo isetyenziswe ekulungiseleleni i-screw granulation kukuba ukufakelwa kwe-fiber bundle kufunyenwe kwi-mold impregnation, kwaye i-fiber ayonakaliswa.Ekugqibeleni, ngokuthelekiswa kwedatha yeempawu zemishini ezimbini, inokubonelela ngenkxaso yobugcisa kwisicelo-icala labasebenzi besayensi kunye nobuchwepheshe xa bekhetha izinto.

Uhlalutyo lwepropati yomatshini
Iifiber zokuqinisa ezongezelelweyo kwi-matrix ye-resin zingenza i-skeleton exhasayo.Xa izinto ezidibeneyo zixhomekeke kumandla angaphandle, iifayili zokuqinisa zinokuthwala ngokufanelekileyo indima yemithwalo yangaphandle;ngelo xesha, inokuthatha amandla ngokuqhekeka, i-deformation, njl., kwaye iphucule iimpawu zemishini ye-resin.

Xa i-glass fiber content inyuka, iifiber zeglasi ezininzi kwizinto ezidibeneyo zixhomekeke kumandla angaphandle.Ngexesha elifanayo, ngenxa yokunyuka kwenani leefayili zeglasi, i-matrix ye-resin phakathi kweefayili zeglasi iba yincinci, eyenza ngakumbi ukwakhiwa kweefreyimu zeglasi eziqinisiweyo;ngoko ke, ukwanda komxholo wefiber yeglasi kwenza ukuba izinto ezidibeneyo zidlulise uxinzelelo olungakumbi kwi-resin kwi-fiber yeglasi phantsi komthwalo wangaphandle, ophucula ngokufanelekileyo iimpawu zokuxinana kunye nokugoba kwezinto ezidibeneyo.
Iimpawu zokuqina kunye ne-flexural zePPS/LGF composite ziphezulu kunezo zePPS/SGF ezidibeneyo.Xa i-mass fraction ye-glass fiber yi-30%, amandla okuqina e-PPS / SGF kunye ne-PPS / LGF edibeneyo yi-110MPa kunye ne-122MPa, ngokulandelanayo;Amandla e-flexural yi-175MPa kunye ne-208MPa, ngokulandelelana;Imoduli ye-flexural elastic yi-8GPa kunye ne-9GPa, ngokulandelelanayo.
Amandla okuqina, amandla okuguquguquka kunye ne-flexural elastic modulus ye-PPS / LGF composite zonyuswe ngo-11.0%, 18.9% kunye ne-11.3%, ngokulandelanayo, xa kuthelekiswa ne-PPS / SGF edibeneyo.Ubude bezinga lokugcinwa kwefiber yeglasi kwizinto ezihlanganisiweyo zePPS/LGF ziphezulu.Ngaphantsi komxholo wefayibha yeglasi efanayo, imathiriyeli edibeneyo inokumelana nomthwalo onamandla kunye neempawu ezingcono zoomatshini.
