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 inyanzeliswe 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 ziphantsi konyango. Olu nyango lubandakanya ukusebenzisa i-agent yokudibanisa, njenge-silane, kumphezulu wefiber. I-ejenti yokudibanisa idala iibhondi zeekhemikhali 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 kwepolymerization 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. Ukuhanjiswa 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 kakhulu ekuveliseni amacandelo e-GFRPC antsonkothileyo ngokuchaneka okuphezulu komgangatho. Kule nkqubo, umxube we-GFRPC otyhidiweyo utofwa phantsi koxinzelelo oluphezulu kwi-mold mold cavity. I-mold ipholile, ibangela ukuba izinto ziqiniswe kwaye zithathe isimo sobumba.
Ukubumba ukunyanzeliswa kukulungele ukuvelisa amacandelo e-GFRPC alula 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, umatshini, kunye nokugqitywa komphezulu, ukunyusa ukusebenza kwawo kunye nobuhle.
I-Anealing yinkqubo yonyango lobushushu ebandakanya ukufudumeza kancinane imathiriyeli ye-GFRPC ukuya kubushushu obuthile kwaye emva koko uyipholise kancinane. Le nkqubo inceda ukukhulula uxinzelelo oluseleyo 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.
