1. Ndeipi girazi fiber?
Girazi machirainoshandiswa zvakanyanya nekuda kwemutengo wavo-zvinobudirira uye zvakanakira zvivakwa, kunyanya mune indasitiri yemanyoro. Pakutanga kwezana ramakore rechi 18, veEuropean vakaziva kuti girazi raigona kupfava kuita mafambiro ekusuka. Iyo bhokisi revaFrench Emperor Napoleon rakatove nemachira ekushongedza akagadzirwafiberglass. Girazi machira ane miviri miviri uye zvipfupi zvipfupi kana maruva. Mafirita egirazi anowanzoshandiswa muzvinyorwa zvekushandisa, mabhandi erabha, mabhandi anodzora, etc. motrocs, etc. mapfupi mafuru anoshandiswa mune isina-yakarukwa emalts, engineering mapuranga uye zvigadzirwa.
Girazi fiber inonakidza yemuviri uye michina yezvimiro, kusununguka kwehunhu, uye mutengo wakaderera uchienzaniswa necarbon fiberZviitire izvo zvinyorwa zvekusarudza kune yakakwirira-performancument incompositions. Mahara egirazi anoumbwa oxides of silika. Magirazi maFlass ane zvakanakisa manhamba akadai sekuve akaderera brittle, simba rakanyanya, rakaderera kuomarara uye kurema kwehuremu.
Girazi fiber rakasimbiswa polymers rine kirasi hombe yemhando dzakasiyana dzemhando dzegirazi, dzakadai seyakafudza machira, machira akachekwa, akarukwa, uyeakachekwa makatambara, uye anoshandiswa kuvandudza michina uye yetatu zvivakwa zve polymer caposite. Girazi machira anogona kuwana huwandu hwekutanga hwekutanga ratios, asi brittleness rinogona kukonzera mafaira ekupwanya panguva yekugadzirisa.
1.Mhando yegirazi fiber
Hunhu hukuru hwegirazi fiber zvinosanganisira zvinotevera zvinhu:
Hazvisi nyore kutora mvura:Girazi fiber kudzokorora kwemvura uye hakuna kukodzera kupfeka, nekuti ziya haribve, kuita kuti munhu anyoro anonzwa kunyorova; Nekuti izvo zvinyorwa hazvina kukanganiswa nemvura, hazvizorega
Inelasticity:Nekuda kwekushaikwa kwekushamisika, mucheka une zvishoma zvisingabvumirwe kutambanudza uye kupora. Naizvozvo, ivo vanoda kurapwa kwepasi kuramba kupenya.
Simba rakakwirira:Fiberglass yakasimba zvakanyanya, zvingangoita yakasimba se kevlar. Nekudaro, kana mafaira abvise mumwe nemumwe, anotyora uye anokonzeresa mucheka kuti atore chitarisiko cheshaggy.
Insulation:Muchapfupi fiber fomu, fiberglass ndeye yakanaka insulator.
Kudzvinyirira:Mota dzinodzora tsime, dzichiita kuti vakwanise kuita machira.
Kupisa kupesana:Misha yegirazi ine yakakwirira kupisa kupesana, inogona kumira tembiricha kusvika 315 ° C: Hazvina kukanganiswa nechiedza chezuva, bleach, blecheria, zvipembenene kana alkalis.
Inosimba:Magirazi maFlass anokanganiswa ne hydrofluorgic acid uye inopisa phosphhoric acid. Sezvo iyo fiber chigadzirwa-chakavakirwa chigadzirwa, mamwe mafaira egirazi anofanirwa kubatwa nehanya, akadai seyakajeka emishini, nekuti mafaira anofanirwa kubaya ganda, saka magurovhosi anofanirwa kupfekwa kana achibata fiberglass.
3. Kugadzira maitiro egirazi fiber
Girazi fiberis is is is is-simbi fiber iyo parizvino inoshandiswa zvakanyanya sezvinhu zveindasitiri. Kazhinji, zvinhu zvekutanga zvegirazi zvegirazi zvinosanganisira zvakasiyana-siyana zvichidyungisa zvichangoitika zvemaminerari uye zvakagadzirwa nemurume, zvikamu zvikuru zviri silica jecha, limestone nesoda ag.
SILICA jecha anoita segirazi raimbova, nepo Soda Ash uye Limestone Batsira kudzikisa tembiricha yekunyungudika. Iyo yakaderera coeff fermans yekuwedzera yakasanganiswa neyakaderera yekubatanidza kuenzaniswa neasbestos uye organic fibers inoita fiberglass zvinhu zvakaderera zvinosimbisa kupisa nekukurumidza.
Girazi machirainogadzirwa nekunyungudika kwakananga, iyo inosanganisira maitiro akadai sekuwedzera, kunyungudika, kupururudza, kufukidza, uye kurongedza, uye kurongedza. Batch ndiyo yekutanga mamiriro ekugadzira girazi, mune iyo huwandu hwenyama dzakanyatso kusanganiswa uye ipapo musanganiswa wacho unotumirwa kuchirimo chekunyungudika pakudziya kwakanyanya kwe1400 ° C. Uku tembiricha kwakakwanira kushandura jecha uye zvimwe zvinongedzo kuita nyika yakanyungudutswa; Girazi rakanyungudutswa rinobva raiyerera mumhepo uye tembiricha inodonha kusvika ku130 ° c.
Munguva yekupururudza kwegirazi machira, girazi rakanyungudutswa rinoyerera nepakati nemakomba akanaka kwazvo. Iyo liner ndiro inotsamwiswa nemagetsi nemagetsi uye tembiricha yayo inodzorwa kuti ichengetedze tarisiro yekugara. Iyo jet yemvura yaishandiswa kutonhora iyo files sezvo iyo yakawana iyo sleeve pane tembiricha yeanenge zana nemakumi mashanu c.
Rwizi rwakasarudzika rwegirazi rakanyungudutswa muchina unokwezverwa kuita mafaira ane diamita kubva ku4 μm kusvika 34 μm. Kunetsana kunopihwa uchishandisa yakakwira mhepo yemhepo uye girazi rakanyungudutswa rinokweverwa muzvivakwa. Muchikamu chekupedzisira, matsika emakemikari ezvinyorwa, mabhendi uye macompling vamiririri vanoiswa kune mafirita. Lubrication inobatsira kuchengetedza mafirita kubva ku learasion sezvo ivo vakaunganidzwa uye vanga mumapaketi. Mushure mekurongedza, mafambi aoma mune ovheni; Mafirita anobva agadzirira kuenderera mberi achigadzira mumachira akachekwa, marwadzo kana yarns.
4.kushandiswa kwegirazi fiber
Fiberglass Icho chinhu chisiri chekormic chisina kupisa uye chengetedza zvinenge makumi maviri neshanu muzana wekusimba kwayo kwekutanga pa540 ° C. Mazhinji makemikari ane zvishoma mhedzisiro pamarara egirazi. Inorganic fiberglass haizoumbwa kana kuderera. Magirazi egirazi anokanganiswa ne hydrofluorgic acid, inopisa phosphhor acid uye yakasimba alkaline zvinhu.
Icho chinhu chakanakisa chemagetsi chinosimbisa zvinhu.Fiberglass machiraIva nezvivakwa zvakadai seyakaderera kunyorova, simba rakanyanya, kupisa kupokana uye kuderera dielectric nguva dzose, kuriita kuti varegedze kusimbiswa kwemabhodhi edunhu redunhu uye kusimbisa varnish.
Iyo yakakwira simba-kune-uremu chiyero cheFiberglass inoita kuti ive yakanakisa zvinyorwa zvekushandisa zvinoda simba rakanyanya uye huremu hushoma. In textile form, this strength can be unidirectional or bidirectional, allowing flexibility in design and cost for a wide range of applications in the automotive market, civil construction, sporting goods, aerospace, marine, electronics, Home and wind energy.
Ivo zvakare vanoshandiswawo mukugadzirwa kwezvivakwa zvemhando, vakadhindwa mabhodhi ematunhu uye akasiyana-siyana ezvigadzirwa. Iyo nyika yepagore yegoridhe fiber kugadzirwa ndeye mando anenge mamirioni 4,5, uye varairidzi vakuru china (60% yemusika chikamu), United States neEuropean Union.
