Summary
Munguva inopfuura hafu yezana remakore, fiber-reinforced composite zvinhu zvakashandiswa zvakanyanya nekuda kwehutano hwavo hwakanaka, uye basa rinokosha rekusimbisa mafiibhi muzvinhu zvakasanganiswa rinozviratidza. Kubva pakuuya kwacomposite zvinhu, mafiibha ekusimbisa akachinja kubva pashinda dzemusikirwo kuenda kune dzakagadzirwa.
Parizvino, iyo inonyanya kusimba fibres inosanganisira girazi fibers, aramid fibers,carbon fibers, etc. Ichi chinyorwa chichasuma maitiro uye kushandiswa kwegirazi fibers yekusimbisa composite.
Chiifiberglass?
Girazi fibers anoshandiswa zvakanyanya nekuda kwekudhura-kushanda uye zvakanaka zvivakwa, kunyanya muindasitiri yecomposites. Kare muzana remakore rechi18, vanhu vokuEurope vakaziva kuti girazi raigona kusonwa kuita shinda dzokuruka. Bhokisi reMambo weFrance Napoleon rakanga ratove nemachira ekushongedza akagadzirwa nefiberglass. Girazi fiber dzine zvese filaments uye mapfupi fiber kana flocs. Girazi filaments inowanzoshandiswa muzvinhu zvakasanganiswa, zvigadzirwa zverabha, mabhandi ekutakura, tarpaulins, nezvimwewo. Mafiinzi mapfupi anonyanya kushandiswa mune zvisiri zvakarukwa, mapurasitiki einjiniya uye zvinhu zvinoumbwa.
Girazi fiber inoyevedza yemuviri uye mekiniki zvivakwa, nyore kugadzira, uye mutengo wakaderera uchienzaniswa nekabhoni fiber inoita kuti ive chinhu chesarudzo chepamusoro-inoita composite application. Girazi fibers inoumbwa neokisidhi ye silica. Girazi faibha dzine yakanakisa mechanicha zvimiro zvakaita sekusanyanya brittle, kusimba kwepamusoro, kuomarara kwakaderera uye kureruka uremu.
Girazi fiber reinforced polymers ine kirasi hombe yemhando dzakasiyana dzegirazi fibers, senge longitudinal fibers, akachekwa fibers, akarukwa mateti, uye.machira akachekwa , uye inoshandiswa kuvandudza michina uye tribological zvimiro zvepolymer composites. Girazi fibers inogona kuwana yakakwira yekutanga chikamu ratios, asi brittleness inogona kukonzera mafiber kutyoka panguva yekugadziriswa.
Tafura inotevera inoratidza mhando dzakasiyana dzegirazi fibers uye zvinyorwa:
Girazi Fiber Properties
Hunhu hukuru hwegirazi fiber zvinosanganisira zvinotevera zvinhu:
Hazvisi nyore kutora mvura: Girazi fiber inodzivirira mvura uye haina kukodzera zvipfeko, nokuti dikita haringasviki, zvichiita kuti munhu akapfeka anzwe akanyorova; nokuti zvinhu hazvina kukanganiswa nemvura, hazvizodzike.
In-elasticity: Nekuda kwekushaya elasticity, jira rine zvishoma inherent kutambanudza uye kupora. Nokudaro, vanoda kurapwa kwepamusoro kuti varambe kuunyana.
High Strength: Fiberglass yakasimba zvakanyanya, inenge yakasimba seKevlar. Zvisinei, kana mafibhi achikweshana, anotsemuka uye anoita kuti jira racho riite shaggy.
Insulation:Muchidimbu fiber fomu, fiberglass yakanaka insulator.
Drapability:Mafibers anonamira zvakanaka, achiita kuti ave akanakira maketeni.
Heat Resistance:Girazi fibers ine high heat resistance, inogona kumira kutonhora kusvika ku 315 ° C, haigadziriswi nechiedza chezuva, bleach, mabhakitiriya, mold, zvipembenene kana alkalis.
Zvinokwanisika: Girazi fiber inobatwa ne hydrofluoric acid uye inopisa phosphoric acid. Sezvo faibha iri chigadzirwa chegirazi, mamwe magirazi egirazi mafibhi anofanirwa kubatwa nekungwarira, senge zvinhu zvemumba zvekudzivirira, nekuti iyo fiber inopera haina kusimba uye inogona kuboora ganda, saka magirovhosi anofanira kupfekwa kana uchibata fiberglass.
Iyo yemuviri uye yemagetsi zvimiro zveyakajairwa yekutengesa girazi fibers inoratidzwa mutafura pazasi:
Glass Fiber Manufacturing Process
Girazi faibha isiri-simbi faibha iyo parizvino inoshandiswa zvakanyanya sechinhu cheindasitiri. Kazhinji, izvo zvakakosha zvegirazi fiber zvinosanganisira zvakasiyana zvicherwa zvechisikigo uye makemikari akagadzirwa nevanhu, izvo zvakakosha ijecha resilica, limestone uye soda ash.
Silica jecha rinoita segirazi rekare, nepo soda ash uye limestone zvichibatsira kudzikisa tembiricha yekunyungudika. The low coefficient of thermal expansion yakasanganiswa ne low thermal conductivity kana ichienzaniswa neasbestos uye organic fibers inoita kuti fiberglass ive chinhu chakadzikama chine dimensionally chinobvisa kupisa nekukurumidza.
Glass Fiber Manufacturing Process Flow Chart
Girazi fiber inogadzirwa nekunyungudika kwakananga, uko kunosanganisira maitiro akadai sekusanganisa, kunyungudika, kuruka, kupeta, kuomesa, uye kurongedza. Iyo batch ndiyo yekutanga mamiriro ekugadzira magirazi, umo huwandu hwezvinhu hwakanyatsosanganiswa, uye musanganiswa unopihwa muchoto chekunyunguduka pakupisa kukuru kwe1400 ° C. Iyi tembiricha yakakwana kushandura jecha uye zvimwe zvinhu kuti zvive zvakanyungudutswa; girazi rakanyungudutswa rinobva rayerera richipinda muinatsi uye tembiricha inodzika kusvika 1370°C.
Panguva yekutenderedzwa kwemagirazi fibers, girazi rakanyungudutswa rinoyerera richibuda nepakati peruoko rine maburi akanyanya kunaka. Iyo liner plate inopisa nemagetsi uye tembiricha yayo inodzorwa kuchengetedza viscosity inogara iripo. Jeti yemvura yakashandiswa kutonhodza filament payaibuda neruoko patembiricha ingangoita 1204°C.

Rukova rwakawedzerwa rwegirazi rakanyungudutswa rinodhonzwa mumichina ine madhayamita kubva pa4 μm kusvika 34 μm. Tension inopiwa uchishandisa high speed winder uye girazi rakanyungudutswa rinodhonzwa kuita filaments. Muchikamu chekupedzisira, makemikoro ekuputira emafuta, mabhanhire uye ma-coupling agents anoshandiswa kune filaments. Kuzora kunobatsira kuchengetedza mafilaments kubva pakunyungudutswa paanenge achiunganidzwa uye akakuvadzwa mumapakeji. Mushure mekuyera, fiber inoomeswa muchoto; mafilaments anobva agadzirira kuti aendeswe kugadziridzwa kuita shinda dzakachekwa, rovings kana shinda.
Kushandiswa kweGmusikanaFiber
Fiberglass inorganic material isingapise uye inoramba iine 25% yesimba rayo rekutanga pa540°C. Mazhinji makemikari ane simba shoma pagirazi fibers. Inorganic fiberglass haigoni kuumba kana kuparara. Girazi fibers inobatwa nehydrofluoric acid, inopisa phosphoric acid uye yakasimba alkaline zvinhu.
Iyo yakanakisa magetsi insulating material. Machira eFiberglass ane zvimiro zvakaita sekudzika kunyura, kusimba kwepamusoro, kupisa kupisa uye yakaderera dielectric kugara, zvichiita kuti ive yakanakira yekusimbisa yeakadhindwa edunhu mabhodhi uye insulating varnishes.
Iyo yakakwira simba-kusvika-huremu reshiyo yefiberglass inoita kuti ive yakanakisa zvinhu zvekushandisa zvinoda simba rakawanda uye huremu hushoma. Muchimiro chemucheka, simba iri rinogona kunge riine unidirectional kana bidirectional, richibvumira kuchinjika mukugadzira uye mutengo wezvakasiyana siyana zvekushandisa mumusika wemotokari, kuvaka kwevagari, zvinhu zvemitambo, ndege, marine, zvemagetsi, Kumba uye simba remhepo.
Iwo anoshandiswawo mukugadzira maumbirwo emakombisi, akadhindwa edunhu mabhodhi uye akasiyana akakosha-chinangwa zvigadzirwa. Kugadzirwa kwepasi rose kwegirazi faibha kwepagore kunosvika matani 4.5 miriyoni, uye vagadziri vakuru iChina (60% mugove wemusika), United States neEuropean Union. (Kwakabva: Carbon Fiber uye Iyo Yakaumbwa Material Tekinoroji)
