1. Chii chinonzi girazi faibha?
Magirazi egirazianoshandiswa zvakanyanya nekuda kwekushandisa mari shoma uye hunhu hwakanaka, kunyanya muindasitiri yekugadzira zvinhu zvinosanganisa makemikari. Kare muzana remakore rechi18, vanhu vekuEurope vakaona kuti girazi raigona kupetwa kuita machira ekuruka. Bhokisi raMambo weFrance Napoleon raive nemachira ekushongedza akagadzirwa nefiberglassMagirazi ane filaments uye mapfupi kana kuti flocs. Filaments egirazi anowanzo shandiswa muzvinhu zvakasanganiswa, zvigadzirwa zverabha, mabhandi ekufambisa, matarpaulins, nezvimwewo. Fibers pfupi dzinonyanya kushandiswa muzvinhu zvisina kurukwa, mapurasitiki einjiniya uye zvinhu zvakasanganiswa.
Hunhu hwegirazi hwefiber hunoyevedza uye hune michina, nyore kugadzira, uye mutengo wakaderera kana tichienzanisa nekabhoni faibhaIta kuti ive chinhu chinosarudzwa pakushandisa zvinhu zvakasiyana-siyana zvine simba guru. Magirazi anoumbwa nemaoxides esilica. Magirazi ane hunhu hwakanaka hwemuchina hwakadai sekusanyanya kuputsika, kusimba kwakanyanya, kuomarara kushoma uye huremu hwakareruka.
Mapolymer akasimbiswa nefiber yegirazi ane mhando dzakasiyana dzefiber yegirazi, dzakadai sefibers refu, fibers dzakachekwa, mat dzakarukwa, uyematinji akachekwa, uye zvinoshandiswa kuvandudza hunhu hwemakemikari uye hwetribological hwepolymer composites. Magirazi egirazi anogona kuwana chiyero chepamusoro chekutanga, asi kuputsika kunogona kukonzera kuti mafirita aputsike panguva yekugadzirisa.
1.hunhu hwegirazi faibha
Hunhu hukuru hwegirazi fiber hunosanganisira zvinotevera:
Hazvisi nyore kunyudza mvura:Fiber yegirazi inodzinga mvura uye haina kukodzera mbatya, nekuti ziya haripindi, zvichiita kuti munhu akapfeka anzwe akanyorova; nekuti jira racho harikanganiswi nemvura, harizodziki
Kusasimba:Nekuda kwekusasimba kwejira, jira iri harina kutwasuka uye kupora zvakanyanya. Saka, rinoda kugadziriswa pamusoro kuti rirambe kukwinya.
Simba Rakakwirira:Girazi reFiberglass rakasimba zvikuru, rakafanana neKevlar. Zvisinei, kana shinda dzikakwizana, dzinotyoka uye dzinoita kuti jira riite serakasvibira.
Kudzivirira:Muchidimbu, fiberglass inodzivirira kupisa zvakanaka.
Kusagadzikana:Matayi acho anomonereka zvakanaka, zvichiita kuti akwanise kushandiswa pamachira.
Kuramba Kupisa:Magirazi epurasitiki haapise zvakanyanya, anogona kutsungirira tembiricha inosvika 315°C, haakanganiswa nezuva, bleach, mabhakitiriya, chakuvhuvhu, zvipembenene kana alkali.
Zvinokanganisa:Magirazi anokanganiswa ne hydrofluoric acid uye hot phosphoric acid. Sezvo fiber iri chigadzirwa chegirazi, mamwe magirazi asina kubikwa anofanira kubatwa nokungwarira, senge zvinhu zvinodzivirira kupisa mumba, nekuti magumo efiber haana kusimba uye anogona kubaya ganda, saka magirovhosi anofanira kupfekwa pakubata fiberglass.
3. Maitiro ekugadzira girazi fiber
Faibha yegiraziifiber isiri yesimbi iyo inoshandiswa zvakanyanya pari zvino sezvinhu zvemaindasitiri. Kazhinji, zvinhu zvekutanga zvefiber yegirazi zvinosanganisira zvicherwa zvakasiyana-siyana zvechisikigo uye makemikari akagadzirwa nevanhu, zvikamu zvikuru ijecha resilica, limestone uye soda ash.
Jecha resilica rinoshanda segirazi, nepo soda ash ne limestone zvichibatsira kuderedza tembiricha yekunyunguduka. Kuwanda kwemafuta ekuwedzera pamwe chete nekupisa kwakaderera kana tichienzanisa neasbestos ne organic fibers kunoita kuti fiberglass ive chinhu chakagadzikana chinobvisa kupisa nekukurumidza.
Magirazi egirazizvinogadzirwa nekunyungudutsa zvakananga, izvo zvinosanganisira maitiro akadai sekusanganisa, kunyungudutsa, kupomba, kupukuta, kuomesa, uye kurongedza. Batch ndiyo mamiriro ekutanga ekugadzira magirazi, umo huwandu hwezvinhu hunosanganiswa zvakanaka uye musanganiswa wacho unotumirwa kuchoto kuti unyungudike patembiricha yepamusoro ye1400°C. Tembiricha iyi yakakwana kushandura jecha nezvimwe zvinoshandiswa kuita mamiriro akanyunguduka; girazi rakanyunguduka rinozoyerera muchina wekuchenesa uye tembiricha inodzikira kusvika 1370°C.
Munguva yekutenderera kwemagirazi, girazi rakanyunguduka rinobuda nepaburi rine maburi madiki. Rinoiswa mu liner plate rinodziiswa nemagetsi uye tembiricha yaro inodzorwa kuti irambe yakasimba nguva dzose. Mvura inoshandiswa kutonhodza filament payaibuda muburi patembiricha inosvika 1204°C.
Rukova rwegirazi rakanyungudutswa runodhonzwa neunyanzvi muzvinhu zvine dhayamita kubva pa4 μm kusvika 34 μm. Kusimba kunowanikwa uchishandisa muchina wekupeta unomhanya uye girazi rakanyungudutswa rinodhonzwa muzvinhu zvine shinda. Padanho rekupedzisira, makemikari anoputirwa nemafuta, mabhindi uye zvinhu zvinobatanidza zvinoiswa pazvinhu zvine shinda. Kuzora kunobatsira kudzivirira zvinhu zvisina shinda kubva pakukuvadzwa sezvazvinounganidzwa uye zvinoputirwa mumapakeji. Mushure mekusaizi, zvinhu zvine shinda zvinoomeswa muovheni; zvinhu zvine shinda zvinozogadzirira kugadziriswazve kuita zvinhu zvine shinda dzakachekwa, tambo kana shinda.
4.kushandiswa kwegirazi faibha
Girazi reFiberglass chinhu chisina makemikari chisingatsvi uye chinochengetedza inenge 25% yesimba rayo rekutanga pa540°C. Makemikari mazhinji haanyanyi kukanganisa fibers dzegirazi. Fiberglass isina makemikari haizoumbi kana kuora. Fibers dzegirazi dzinokanganiswa ne hydrofluoric acid, hot phosphoric acid uye zvinhu zvine alkaline yakasimba.
Chinhu chakanaka kwazvo chekudzivirira kupisa kwemagetsi.Machira eFiberglassdzine zvinhu zvakaita sekunyorova kushoma, simba guru, kusapisa uye kusachinja-chinja kwe dielectric, zvichiita kuti dzive dzakanakira mabhodhi ecircuit akadhindwa uye mavarnish ekudzivirira kupisa.
Chiyero chakakwirira che fiberglass chesimba-ku-huremu chinoita kuti ive chinhu chakanakisa chekushandisa chinoda simba rakawanda uye huremu hushoma. Muchimiro chemucheka, simba iri rinogona kuva rakasiyana kana kuti rakasiyana-siyana, zvichibvumira kuchinjika mukugadzirwa uye mutengo wezvishandiso zvakasiyana-siyana mumusika wemotokari, kuvaka kwezvivakwa, zvinhu zvemitambo, zvendege, zvemugungwa, zvemagetsi, zvemumba nemhepo.
Dzinoshandiswawo mukugadzira zvinhu zvinosanganisa zvivakwa, mabhodhi edunhu akadhindwa uye zvigadzirwa zvakasiyana-siyana zvine chinangwa chakakosha. Kugadzirwa kwefaibha yegirazi pagore pasi rose kunodarika matani angangoita mamiriyoni mana nehafu, uye vagadziri vakuru iChina (60% yemusika), United States neEuropean Union.
