1. Chii chinonzi fiber yegirazi?
Girazi fibersanoshandiswa zvakanyanya nekuda kwekudhura-kushanda uye zvivakwa zvakanaka, 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 akagadzirwafiberglass. 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 yemagetsi zvivakwa, nyore kugadzira, uye mutengo wakaderera uchienzaniswacarbon fiberita kuti ive chinhu chesarudzo chepamusoro-inoshanda 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.
1.maitiro egirazi fiber
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
Inelasticity: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.
3. Kugadzira nzira yegirazi fiber
Girazi fiberis a non-metallic fiber 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.
Girazi fiberszvinogadzirwa nekunyunguduka kwakananga, kunosanganisira maitiro akadai sekusanganisa, kunyungudika, kutenderera, kupeta, kuomesa, uye kurongedza. Batch ndiyo mamiriro ekutanga ekugadzira magirazi, umo huwandu hwezvinhu hwakanyatsosanganiswa uye ipapo musanganiswa unotumirwa kuchoto 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 mhepo inomhanya kwazvo uye girazi rakanyungudutswa rinodhonzwa kuita filaments. Muchikamu chekupedzisira, makemikoro ekuputira emafuta, mabhanhire uye ekubatanidza anoshandiswa kune filaments. Kuzora kunobatsira kuchengetedza mafilaments kubva paabrasion sezvaanounganidzwa uye kukuvadzwa mumapakeji. Mushure mekuyera, fiber inoomeswa muchoto; mafilaments anobva agadzirira kuti aendeswe kugadziridzwa kuita shinda dzakachekwa, rovings kana shinda.
4.kushandiswa kwegirazi fiber
Fiberglass chinhu chisingapise uye chinochengeta 25% yesimba rayo rekutanga pa540°C. Mazhinji makemikari ane zvishoma zvaanoita pagirazi fibers. Inorganic fiberglass haigoni kuumba kana kushatisa. Girazi fibers inobatwa nehydrofluoric acid, hot phosphoric acid uye yakasimba alkaline zvinhu.
Iyo yakanakisa magetsi insulating material.Fiberglass machiravane zvivakwa zvakaita senge kuderera kwemwando, kusimba kwepamusoro, kupisa kupisa uye yakaderera dielectric kugara, zvichiita kuti ive yakanaka 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.
