Kuvandudzwa kweGFRP kunobva mukuwedzera kuri kuita kudiwa kwezvinhu zvitsva zviri kuita zvepamusoro, zvakareruka muhuremu, zvisingaite corrosion, uye simba rakawanda. Nekuvandudzwa kwesainzi yezvinhu uye nekuenderera mberi kwekuvandudza tekinoroji yekugadzira, GFRP yakawana zvishoma nezvishoma zvakasiyana-siyana zvekushandisa munzvimbo dzakasiyana siyana.GFRP kazhinji inefiberglassuye resin matrix. Kunyanya, GFRP ine zvikamu zvitatu: fiberglass, resin matrix, uye interfacial agent. Pakati pavo, fiberglass chikamu chakakosha cheGFRP. Fiberglass inogadzirwa nekunyunguduka uye kudhirowa girazi, uye chikamu chavo chikuru isilicon dioxide (SiO2). Magirazi egirazi ane mabhenefiti ekusimba kwepamusoro, kushomeka kwakadzikira, kupisa, uye marara kuramba kupa simba uye kuoma kune izvo zvinhu. Chechipiri, iyo resin matrix ndiyo inonamatira yeGFRP. Anowanzo shandiswa resin matrices anosanganisira polyester, epoxy, uye phenolic resins. Resin matrix ine yakanaka adhesion, makemikari kuramba, uye kukanganisa kuramba kugadzirisa uye kuchengetedza fiberglass uye kutamisa mitoro. Interfacial agents, kune rumwe rutivi, vanoita basa rakakosha pakati pefiberglass uye resin matrix. Interfacial agents anogona kuvandudza kunamatira pakati pefiberglass uye resin matrix, uye kuwedzera ma mechanic zvivakwa uye kusimba kweGFRP.
General maindasitiri synthesis yeGFRP inoda matanho anotevera:
(1) Fiberglass kugadzirira:Iyo girazi zvinhu zvinopiswa uye kunyungudutswa, uye inogadzirirwa mune akasiyana maumbirwo uye saizi yefiberglass nenzira dzakadai sekudhirowa kana kupfapfaidza.
(2) Fiberglass Pretreatment:Yemuviri kana kemikari yepamusoro kurapwa kwefiberglass kuti iwedzere kushata kwepamusoro uye kunatsiridza kunamatira kwechiso.
(3) Kurongeka kwefiberglass:Govera iyo pre-yakagadziriswa fiberglass mumidziyo yekuumba zvinoenderana nezvinodiwa zvekugadzira kuti ugadzire yakafanotemerwa faibha kuronga chimiro.
(4) Coating resin matrix:Pfekedza resin matrix zvakafanana pafiberglass, pfekedza masumbu efiber, uye isa mafiber mukubatana zvizere neresin matrix.
(5) Kurapa:Kurapa resin matrix nekudziisa, kudzvanya, kana kushandisa zvinhu zvekubatsira (semuenzaniso mushonga wekurapa) kugadzira chimiro chakasimba chemusanganiswa.
(6) Mushure mekurapwa:Iyo GFRP yakarapwa inoiswa kune mushure mekurapa maitiro sekuchekeresa, kukwenenzverwa, uye pendi kuti iwane yekupedzisira yepamusoro yemhando uye chitarisiko chinodiwa.
Kubva pamusoro pekugadzirira maitiro, zvinogona kuonekwa kuti mukugadzirisa kweGFRP kugadzirwa, kugadzirira uye kurongeka kwefiberglass kunogona kugadziriswa maererano nezvinangwa zvakasiyana-siyana, matrices akasiyana-siyana ekushandiswa kwakasiyana-siyana, uye nzira dzakasiyana-siyana dzemashure dzinogona kushandiswa kubudirira kugadzirwa kweGFRP kune zvakasiyana-siyana zvekushandisa. Kazhinji, GFRP inowanzova nemhando dzakasiyana dzezvivakwa zvakanaka, izvo zvinotsanangurwa zvakadzama pazasi:
(1) Huremu:GFRP ine yakaderera chaiyo giravhiti kana ichienzaniswa neyechinyakare simbi zvinhu, uye saka ine huremu huremu. Izvi zvinoita kuti zvive zvinobatsira munzvimbo dzakawanda, senge aerospace, mota, uye zvemitambo zvemitambo, uko huremu hwakafa hwechimiro hunogona kudzikiswa, zvichikonzera kuvandudzwa kwekuita uye kushanda kwemafuta. Inoshandiswa kune zvivakwa zvekuvaka, huremu hwemhando yeGFRP inogona kunyatso kudzikisa huremu hwezvivakwa zvepamusoro.
(2) Kusimba Kwakakwirira: Fiberglass-yakasimbiswa zvinhuvane simba rakakwirira, kunyanya kusimba kwavo uye kushanduka kwesimba. Iko kusanganiswa kwefiber-reinforced resin matrix uye fiberglass inogona kumira mitoro mikuru uye kushushikana, saka izvo zvinhu zvinokunda mumakanika zvinhu.
(3) Corrosion resistance:GFRP ine yakanakisa corrosion resistance uye haibatike nekuora media senge acid, alkali, uye mvura yemunyu. Izvi zvinoita kuti zvinhu zviri munzvimbo dzakasiyana-siyana dzakaoma ive mukana wakakura, senge mumunda weinjiniya yemugungwa, midziyo yemakemikari, uye matangi ekuchengetedza.
(4) yakanaka insulating zvivakwa:GFRP ine yakanaka insulating zvivakwa uye inogona kunyatso patsanura emagetsi uye yekupisa simba conduction. Izvi zvinoita kuti zvinhu zvishandiswe zvakanyanya mumunda weinjiniya yemagetsi uye yekusarudzika yekupisa, sekugadzira mabhodhi edunhu, maredhi ekudzivirira, uye zvinopisa zvekuzviparadzanisa nevamwe.
(5) Kudzivirira kwakanaka kwekupisa:GFRP inekupisa kwakanyanyauye inokwanisa kuchengetedza kushanda kwakadzikama munzvimbo dzepamusoro-tembiricha. Izvi zvinoita kuti ishandiswe zvakanyanya muaerospace, petrochemical, uye minda yekugadzira magetsi, sekugadzira gasi turbine injini blades, partitions yechoto, uye zvinopisa magetsi emidziyo yemidziyo.
Muchidimbu, GFRP ine zvakanakira simba repamusoro, huremu, corrosion resistance, yakanaka insulating properties, uye heat resistance. Izvi zvivakwa zvinoita kuti ive chinhu chinoshandiswa zvakanyanya mukuvaka, aerospace, mota, magetsi, uye maindasitiri emakemikari.
