Intshayelelo
I-Glass Fiber eQiniswa nePolycarbonate(I-GFRPC) ivele njenge-frontrunner kwindawo yezinto eziphezulu zokusebenza, amashishini achukumisayo anamandla akhethekileyo, ukuqina, kunye nokungafihli.Ukuqonda inkcazo kunye nokudityaniswa kwe-GFRPC kubalulekile ukuxabisa iipropati zayo ezimangalisayo kunye nezicelo ezahlukeneyo.
Ukuchaza i-Glass Fiber Reinforced Polycarbonate (GFRPC)
I-Glass Fiber Reinforced Polycarbonate (GFRPC) yimpahla edibeneyo edibanisa amandla kunye nokuqina kweefayili zeglasi kunye ne-ductility kunye nokucaca kwe-polycarbonate resin.Le ngxubevange yeepropati inika i-GFRPC iseti eyodwa yeempawu eziyenza ibe sisixhobo esifunwa kakhulu kuluhlu olubanzi lwezicelo.
Ukuphonononga iNdibaniselwano yeGlass Fiber Reinforced Polycarbonate (GFRPC)
I-synthesis ye-Glass Fiber Reinforced Polycarbonate (GFRPC) ibandakanya inkqubo yamanyathelo amaninzi adibanisa ngokucophelela iifayili zeglasi kwi-polycarbonate matrix.
1. Ukulungiswa kweFayibha yeglasi:
Iintsinga zeglasi, icandelo eliqinisayo le-GFRPC, zenziwe ngesanti ye-silica, ubutyebi bendalo obuyintabalala kuqweqwe loMhlaba.Isanti ihlanjululwa kuqala kwaye inyibilikiswe kumaqondo aphezulu, malunga ne-1700 ° C, ukwenza iglasi etyhidiweyo.Le glasi ityhidiweyo iye inyanzelwe ngemilomo ecolekileyo, yenze imicu emincinci yeglasi.
Idayamitha yale micu yeglasi inokwahluka ngokuxhomekeke kwisicelo esifunwayo.Kwi-GFRPC, iintsinga zihlala kuluhlu lwe-3 ukuya kwi-15 ye-micrometer ububanzi.Ukuphucula ukunamathela kwabo kwi-polymer matrix, iifiber zeglasi zifumana unyango olungaphezulu.Olu nyango lubandakanya ukusebenzisa i-agent yokudibanisa, njenge-silane, kumphezulu wefiber.I-ejenti yokudibanisa idala amabhondi ekhemikhali phakathi kweefayili zeglasi kunye ne-polymer matrix, ukuphucula ukugqithiswa koxinzelelo kunye nokusebenza ngokubanzi.
2. Ukulungiselela iMatrix:
Izinto zematrix kwi-GFRPC yipolycarbonate, ipolymer ye-thermoplastic eyaziwa ngokungafihli, ukomelela, kunye nokuxhathisa impembelelo.Ipolycarbonate iveliswa ngepolymerization reaction ebandakanya iimonomers ezimbini eziphambili: bisphenol A (BPA) kunye nephosgene (COCl2).
Ukusabela kwe-polymerization ngokuqhelekileyo kuqhutyelwa kwindawo elawulwayo kusetyenziswa i-catalyst ukukhawulezisa inkqubo.Isiphumo se-polycarbonate resin yi-viscous liquid kunye nobunzima obukhulu be-molecular.Iipropati ze-polycarbonate resin, ezifana nobunzima be-molecular kunye nobude be-chain, zinokuthi zilungelelaniswe ngokulungelelanisa iimeko zokusabela kunye nenkqubo ye-catalyst.
3. Ukudibanisa kunye nokuxuba:
Iifiber zeglasi ezilungisiweyo kunye ne-polycarbonate resin zihlanganiswa kwisinyathelo sokudibanisa.Oku kubandakanya ukuxuba ngokucokisekileyo kusetyenziswa ubuchule obufana ne-twin-screw extrusion ukufezekisa ukusabalalisa okufanayo kweentsinga ngaphakathi kwe-matrix.Ukusasazwa kweentsinga kuchaphazela kakhulu iimpawu zokugqibela zemathiriyeli edibeneyo.
I-twin-screw extrusion yindlela eqhelekileyo yokudibanisa i-GFRPC.Kule nkqubo, iifiber zeglasi kunye ne-polycarbonate resin zondliwa kwi-twin-screw extruder, apho zixhomekeke kwi-chearing mechanical kunye nobushushu.Amandla okucheba aqhekeza izithungu zemicu yeglasi, zisasazeke ngokulinganayo kwintlaka.Ubushushu bunceda ukuthambisa i-resin, ukuvumela ukusasazeka kwefiber engcono kunye nokuhamba kwe-matrix.
4. Ukubumba:
Umxube odityanisiweyo we-GFRPC uye wabunjwa ube kwimilo enqwenelekayo ngokusebenzisa ubuchule obahlukeneyo, kubandakanywa ukubumba inaliti, ukubumba ucinezelo, kunye ne-extrusion yamaphepha.Iiparamitha zenkqubo yokubumba, ezifana nobushushu, uxinzelelo, kunye nezinga lokupholisa, lichaphazela kakhulu iimpawu zokugqibela zezinto eziphathekayo, izinto ezichaphazelayo ezifana ne-fiber orientation kunye ne-crystallinity.
Ukubumba isitofu bubuchule obusetyenziswa ngokubanzi ekuveliseni amacandelo e-GFRPC antsonkothileyo ngokuchaneka okuphezulu.Kule nkqubo, umxube we-GFRPC otyhidiweyo utofwa phantsi koxinzelelo oluphezulu kwi-mold mold cavity.I-mold ipholile, ibangela ukuba izinto ziqiniswe kwaye zithathe ubume be-mold.
Ukubumba ukunyanzeliswa kulungele ukuvelisa amacandelo e-GFRPC amcaba okanye alula.Kule nkqubo, umxube we-GFRPC ubekwe phakathi kweehafu ezimbini zokubumba kwaye uphantsi koxinzelelo oluphezulu kunye nobushushu.Ubushushu bubangela ukuba izinto zithambe kwaye zihambe, zizalise i-mold cavity.Uxinzelelo ludibanisa izinto eziphathekayo, luqinisekisa ukuxinana okufanayo kunye nokusabalalisa ifayibha.
I-extrusion yamaphepha isetyenziselwa ukuvelisa amaphepha e-GFRPC aqhubekayo.Kule nkqubo, umxube we-GFRPC otyhidiweyo unyanzeliswa ngokufa kwe-slit, ukwenza iphepha elincinci lezinto eziphathekayo.Iphepha liyapholiswa kwaye lidluliselwe kwiirola ukulawula ubukhulu kunye neempawu zayo.
5. Emva kokulungiswa:
Ngokuxhomekeke kwisicelo esithile, amacandelo e-GFRPC anokuthi afumane unyango lwasemva kokulungiswa, okufana nokuqhotyoshwa, ukwenziwa kwemishini, kunye nokugqitywa komphezulu, ukunyusa ukusebenza kwawo kunye nobuhle.
I-Anealing yinkqubo yonyango lobushushu ebandakanya ukufudumeza kancinane imathiriyeli ye-GFRPC kubushushu obuthile kwaye emva koko uyipholise kancinci kancinci.Le nkqubo inceda ukukhulula uxinzelelo olushiyekileyo kwizinto eziphathekayo, ukuphucula ukuqina kwayo kunye ne-ductility.
Umatshini usetyenziselwa ukwenza iimilo ezichanekileyo kunye neempawu kumacandelo e-GFRPC.Iindlela ezahlukeneyo zobuchwephesha, ezinje ngokungqusha, ukujika, kunye nokugrumba, zinokusetyenziswa ukufikelela imilinganiselo enqwenelekayo kunye nokunyamezelana.
Unyango lokugqiba umphezulu lunokuphucula inkangeleko kunye nokuqina kwamalungu e-GFRPC.Olu nyango lunokubandakanya ukupeyinta, ukucwenga, okanye ukufaka isambatho esikhuselayo.
