Girazi fiber inogona kukamurwa kuita fiber inoenderera, yakatarwa kureba fiber uye girazi mvere zvichienderana nechimiro uye kureba.Zvinoenderana nekuumbwa kwegirazi, inogona kupatsanurwa kuita alkali-isina, makemikari-resistant, yakakwira alkali, yepakati alkali, yakasimba simba, yakakwira elastic modulus uye alkali-resistant (alkali-resistant) girazi fibers.
Izvo zvakakosha zvekugadzira girazi fiber ijecha requartz, alumina uye pyrophyllite, limestone, dolomite, boric acid, soda ash, mirabilite uye fluorite.Nzira dzekugadzira dzinogona kukamurwa kuita zvikamu zviviri: imwe ndeyekuita zvakananga girazi rakanyungudutswa kuita fiber;Imwe ndeyekuti girazi rakanyungudutswa rinogadzirwa kuita mabhora egirazi kana matanda ane dhayamita ye20mm, uye yobva yapiswa uye yakanyungudutswa nenzira dzakasiyana-siyana kugadzira fiber dzakanyanya dhayamita ye3 ~ 80 μ m.Isingaperi-kureba faibha yakagadzirwa nemichina yekudhirowa sikweya nzira kuburikidza neplatinamu alloy ndiro inodaidzwa kuti inoenderera girazi faibha, inowanzozivikanwa sefaibha refu.Discontinuous fibers yakagadzirwa ne roller kana air flow inonzi fixed-length glass fibers, inowanzonzi mapfupi.
Girazi fiber yakakamurwa kuita mamakisi akasiyana zvichienderana nekuumbwa kwayo, zvivakwa uye mashandisiro.Zvinoenderana neyakajairwa giredhi (ona tafura), E-giredhi girazi fiber ndiyo inonyanya kushandiswa uye inoshandiswa zvakanyanya mumagetsi ekudzivirira zvinhu.Kirasi s ndeye fiber yakakosha.
Girazi rinoshandiswa kukuya girazi faibha kugadzira girazi fiber rakasiyana nezvimwe zvigadzirwa zvegirazi.Magirazi ezvikamu zvefibers akatengeswa pasi rose ndeaya anotevera:
E-girazi
Iyo inozivikanwawo segirazi-isina alkali, igirazi reborosilicate.Parizvino, ndiyo inonyanya kushandiswa girazi fiber, iyo ine yakanaka yekuvharisa magetsi uye mechanical properties.Inoshandiswa zvakanyanya mukugadzirwa kwegirazi fiber yekuvharisa magetsi uye girazi fiber yegirazi fiber yakasimbiswa plastiki.Kukanganisa kwayo ndeyekuti zviri nyore kusvibiswa neinorganic acids, saka haina kukodzera kune acid nharaunda.
C-girazi
Girazi fiber tsvimbo, inozivikanwawo segirazi-yepakati-alkali girazi, inoratidzirwa nekunakisisa kwemakemikari, kunyanya acid kuramba, pane alkali-isina girazi, asi kushanda kwayo kwemagetsi hakuna kunaka, uye simba rayo remuchina i10% ~ 20% yakaderera pane iyo alkali-isina girazi fiber.Kazhinji, yekunze yepakati-alkali girazi faibha ine imwe huwandu hweboron trioxide, nepo China yepakati-alkali girazi fiber haina boron zvachose.Munyika dzekunze, yepakati-alkali girazi faibha inongoshandiswa kugadzira girasi-resistant girazi fiber zvigadzirwa, senge girazi faibha pamusoro wakanzwa, uye zvakare inoshandiswa kusimbisa asphalt denga rezvinhu.Nekudaro, muChina, yepakati-alkali girazi faibha account inopfuura hafu (60%) yegirazi faibha kugadzirwa, uye inoshandiswa zvakanyanya mukusimbisa girazi faibha yakasimbiswa epurasitiki uye kugadzirwa kwesefa machira uye kuputira machira, nekuti mutengo wayo ndewe. yakaderera pane iyo alkali-isina girazi fiber uye ine kukwikwidza kwakasimba.
high simba girazi fiber
Iyo inoratidzirwa nepamusoro simba uye yakakwirira modulus.Simba rayo rimwechete rinosimba i2800MPa, iyo inenge 25% yakakwirira kudarika iyo alkali-isina girazi fiber, uye elastic modulus yayo i86000MPa, iyo yakakwirira kudarika yeE-glass fiber.Zvigadzirwa zveFRP zvinogadzirwa nazvo zvinonyanya kushandiswa muindasitiri yemauto, nzvimbo, bulletproof nhumbi dzokurwa uye zvemitambo.Nekudaro, nekuda kwemutengo wakakwira, haigone kuve yakakurumbira mukushandiswa kwehurumende ikozvino, uye nyika inobuda ingangoita zviuru zvematani.
AR girazi fiber
Iyo inozivikanwawo se alkali-resistant glass fiber, alkali-resistant glass fiber is the rib material of glass fiber reinforced (simende) kongiri (GRC for short), inova 100% inorganic fiber uye inotsiva simbi neasbestos mune isiri-load. -kutakura simenti zvikamu.Alkali-resistant glass fiber inoratidzwa neakanaka alkali resistance, inobudirira kuramba kukoromoka kwezvinhu zvakakwirira-alkali mu simenti, yakasimba grip, yakanyanyisa kunyungudika modulus, kupindirana kwesimba, kusimba kwesimba uye kubhenda simba, kusapisa kwakasimba, chando kuramba, tembiricha uye. humidity shanduko yekudzivirira, yakanakisa kutsemuka kuramba uye kusamira, yakasimba designability uye nyore kuumba.Alkali-resistant glass fiber imhando itsva inoshandiswa zvakanyanya mukusimba kwepamusoro yakasimbiswa (simende) kongiri.
Girazi
Iyo inozivikanwawo seyakakwira alkali girazi, igirazi resodium silicate girazi, risingawanzo shandiswa kugadzira girazi fiber nekuda kwekushomeka kwayo kwemvura.
E-CR girazi
Iyo yakagadziridzwa boron-isina uye alkali-isina girazi, iyo inoshandiswa kugadzira girazi faibha ine yakanaka acid inodzivirira uye kusamira kwemvura.Kupokana kwayo kwemvura kuri nani ka7-8 pane iyo alkali-isina girazi faibha, uye yayo asidi kuramba iri nani kupfuura yepakati-alkali girazi fiber.Iri rudzi rutsva rwakanyanya kugadzirirwa mapaipi epasi pevhu uye matangi ekuchengetedza.
D girazi
Iyo inozivikanwawo seyakaderera dielectric girazi, inoshandiswa kugadzira yakaderera dielectric girazi fiber ine yakanaka dielectric simba.
Pamusoro peiyo iri pamusoro pegirazi fiber components, itsva alkali-isina girazi faibha yakabuda, iyo isina boron zvachose, nokudaro kuderedza kusvibiswa kwezvakatipoteredza, asi ayo emagetsi ekudzivirira uye mechanical properties akafanana neaya echinyakare E-girazi.Mukuwedzera, kune rudzi rwegirazi fiber ine zvikamu zviviri zvegirazi, iyo yakashandiswa mukugadzirwa kwegirazi mvere, uye inonzi inokwanisa kuita seFRP kusimbisa.Pamusoro pezvo, kune fluorine-isina girazi fiber, inova yakagadziridzwa alkali-isina girazi faibha yakagadziridzwa kuitira kuchengetedza kwezvakatipoteredza zvinodiwa.
Kuziva yakakwira alkali girazi fiber
Nzira iri nyore yekuongorora ndeyekubika fiber mumvura inopisa kwemaawa 6-7.Kana yakakwira alkali glauber's salt fiber, mushure mekufashaira mvura, faibha iri muwarp uye weft directions ichange yave.
Zviyero zvese zvakasununguka.
Zvinoenderana nezviyero zvakasiyana, kune nzira dzakawanda dzekuisa girazi fibers, kazhinji kubva pakuona kwehurefu uye dhayamita, kuumbwa uye kuita.
