Ukuphuhliswa kwe-GFRP Stems ukusuka kwimfuno eyandayo yezixhobo ezitsha ezisebenza ngaphezulu, zikhanya ubunzima, ukunganyange okungakumbi kokungasebenzi kakuhle. Ngophuhliso lweSayensi yeZixhobo kunye nokuphuculwa okuqhubekayo kwetekhnoloji yokwenziwa, i-GFRP ifumene ngokuthe ngcembe izicelo ezibanzi zecandelo lahlukeneyo.GFRP ngokubanzi lineI-fiberglasskunye ne-resn matrix. Ngokukodwa, i-GFRP iquka iinxalenye ezintathu: I-fiberglass, i-resn matrix, kunye nearhente edibeneyo. Phakathi kwawo, i-fiberglass yinxalenye ebalulekileyo ye-GFRP. I-fiberglass yenziwa ngokunyibilika kwaye itsile iGlasi, kwaye eyona nto iphambili i-silicon dioksi (sio2). Iintsinga zeglasi zinezibonelelo zamandla aphezulu, ubushushu, ubushushu, kunye nokunganyangeki kosulelo ukubonelela ngamandla kunye nokukhubazeka kwento leyo. Okwesibini, i-risn matrix yi-adhees kwi-gfrp. I-relin esetyenziswayo isetyenziswa imatriki ibandakanya i-polyester, i-Eposyy, kunye ne-feolins. I-Resn Matrix ine-adhees elungileyo, ukumelana nemichiza, kunye nokungaxhathisi kwempembelelo ukulungisa nokukhusela i-fiberglass kunye nokudlulisela imithwalo. Iiarhente ezinkohlakeleyo, kwelinye icala, zidlale indima ephambili phakathi kwe-fiberglass kunye ne-resn matrix. Iiarhente ezinkohlakeleyo zinokuphucula ukubika phakathi kwe-fiberglass kunye ne-resn matrix, kwaye iphucule iipropathi zoomatshini kunye nokuqina kwe-GFRP.
I-General Synthesis Synthesis ye-GFRP ifuna la manyathelo alandelayo:
(1) Ukulungiselela iFiberglass:Izinto zeglasi ziyatshiswa kwaye zinyibilikisiwe, kwaye zilungiselelwe iimilo ezahlukileyo kunye nobukhulu we-fiberglass yeendlela ezinjengokuzoba okanye ukutshiza.
.Ukuphathwa komzimba okanye umphezulu wekhemikhali ye-fiberglass ukuze kwandise ubungqingqwa babo obungaphezulu kunye nokuphucula ubudlelwane obuhlanganyelweyo.
(3) Ukucwangciswa kwe-fiberglass:Hambisa i-fiberglass yangaphambi kokuba iphathwe kwangaphambili kwi-fiberting shalting ngokweemfuno zoyilo ukwenza umsebenzi omiselwe kwangaphambili.
(4) Ukudibana kwakhona i-matrix:I-COATR ye-risn matrix ngokungalinganiyo kwi-fiberglass, inqamle iintsinga zefayibha, kwaye ibeka ii-fibers zinxibelelana ngokupheleleyo neMatrix ye-resen.
(5) Unyango:Ukunyanga i-matrix ye-resin ngokufudumeza, ukucinezela, okanye ukusebenzisa izixhobo ezincedisayo (umz.
(6) Unyango lwasemva kwexesha:I-GFRP enyangekelweyo iphikiswa kwiinkqubo zonyango ezinyangekileyo ezinjengokutyhafiswa, ipolishe, kunye nokupeyinta ukufezekisa umgangatho wokugqibela kunye neemfuno zenkangeleko yokugqibela.
Ukusuka kwinkqubo yokulungiselela ngasentla, inokubonwa ukuba kwinkqubo yeImveliso ye-GFRP, Ulungiselelo kunye nolungiselelo lwe-fiberg lunokuhlengahlengiswa ngokweenkqubo ezahlukeneyo zenkqubo, ii-retin ezahlukeneyo zematriki yezicelo ezahlukeneyo, kwaye iindlela ezahlukeneyo zokulungisa zinokusetyenziselwa ukufezekisa imveliso ye-GFRP yezicelo ezahlukeneyo. Ngokubanzi, i-GFRP ihlala inezinto ezahlukeneyo zepropathi, ezichazwe kwiinkcukacha ezingezantsi:
(1) ukukhanyaI-GFRP ine-gravies ephantsi ethe tyaba ngokuthelekiswa nezinto zentsimbi zemveli, kwaye ke iya kulula. Oku kwenza ukuba kube lula kwiindawo ezininzi, ezinje nge-aerospace, izithuthi, kunye nezixhobo zemidlalo, apho ubunzima besakhiwo esifihliweyo sinokuncitshiswa, sibangelwa kukuphuculwa kwentsebenzo kunye nokusebenza kakuhle kwemali. Isetyenziswe kwizakhiwo, ubume bokukhanya kwe-GFRP bunokunciphisa ngokufanelekileyo ubunzima bezakhiwo eziphakamileyo.
(2) Amandla aphezulu: Izinto ze-figllassYiba namandla aphezulu, ngakumbi amandla abo obuzinxunguphalo kunye namandla abo obuguqukayo. Umdibaniso we-fiber-oqingqiweyo i-wibern matrix kunye ne-fiberglass inokumelana nemithwalo enkulu kunye noxinzelelo, ke izinto eziphezulu zigqwesileyo kwiipropathi zoomatshini.
(3) Ukunganyangeki kwe-corrosion:I-GFRP inesibindi sokunganyangeki kakuhle kwaye ayikhathalelwanga kwimithombo yeendaba ezongalisayo njengeatid, ialkali, kunye namanzi anetyiwa. Oku kwenza ukuba lo mxholo kwiindawo ezahlukeneyo ezinzima zinenzuzo enkulu, njengakwicandelo lobunjineli base manzi, izixhobo zekhemikhali, kunye neetanki zokugcina.
(4) Iipropathi ezifanelekileyo zokuthambisa:I-GFRP ineepropathi ezifanelekileyo zokuthambisa kwaye inokuthi ihambelane nendlela yokuphucula i-elektromagnetic kunye nenkcitho yamandla. Oku kwenza ukuba izinto zisetyenziswe ngokubanzi kwicandelo lobuNjineli boMbane kunye nokuZahlula ngokuthe hla, njengokwenziwe kweeplanga zedolophu, imikhono efakwayo, kunye nezinto ezinodwa zodwa.
(5) Ukumelana nobushushu obulungileyo:I-GFRP inayoUkumelana nobushushu obuphezulukwaye uyakwazi ukugcina intsebenzo yezinzile kwiindawo zobushushu obuphakamileyo. This makes it widely used in aerospace, petrochemical, and power generation fields, such as the manufacture of gas turbine engine blades, furnace partitions, and thermal power plant equipment components.
Kwisishwankathelo, i-GFRP ineengenelo zamandla aphakamileyo, ukunyangwa kokukhanya, iipropathi ezifanelekileyo zokuthambisa, kunye nokuxhathisa ubushushu. Ezi ndawo zenza ukuba zibe yinto esetyenziswayo ekwakhiweni, i-aerospace, inqwelo moya, amandla kunye namashishini emichiza.
