Chii chinonzi fiberglass?

Mafuta egirazi anoshandiswa zvakanyanya nekuda kwemutengo wavo-zvinobudirira uye zvivakwa zvakanaka, kunyanya mune indasitiri yemasendimita. Pakutanga kwezana ramakore rechi 18, veEuropean vakaziva kuti girazi raigona kupfava kuita mafambiro ekusuka. Bhokisi remubhokisi reFrance Napoleon rakatove nemachira ekushongedza akagadzirwa neFiberglass. Girazi machira ane miviri miviri uye zvipfupi zvipfupi kana maruva. Mafirti egirazi anowanzoshandiswa muzvinyorwa zvekushandisa, mabhandi erabha, mabhandi anodzora, etc.-motels, etc. pfupi mafuru anoshandiswa mune isina-kurwadza mats, engineering purasitiki 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 yakasimbiswa polymers ine kirasi hombe yemhando dzakasiyana dzemhando dzegirazi, dzakadai seyakafutisa tambo,Yakachekwa machira, akarukwa mats, 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.

girazi fiber zvivakwa

Hunhu hukuru hwegirazi fiber zvinosanganisira zvinotevera zvinhu:

Hazvisi nyore kutora mvura:Girazi fiberKo kudzvanywa kwemvura uye hakuna kukodzera kuti nguo, nekuti ziya racho harizobatwi, kuita kuti vanosekerere kunzwa; Nekuti zvinyorwa hazvina kukanganiswa nemvura, hazvizotyire.

Inelasticity: Nekuda kwekushaikwa kweElasticity, mucheka une zvishoma zvisingabvumirwe kutambanudza uye kupora. Naizvozvo, ivo vanoda kurapwa kwepasi kuramba kupenya.

Simba rakakwirira:Fiberglass yakasimba kwazvo, ingangoita yakasimba se kevlar. Nekudaro, kana mafaira abvise mumwe nemumwe, anotyora uye anokonzeresa mucheka kuti atore chitarisiko cheshaggy.

Insulation: Muchipfupi fiber fomu, fiberglass ndeye yakanakisa insulator.

Kudhirowa: Mota inodonha zvakanaka, ichivaita ivo vane machira.

Kupisa kupokana: Magirazi machira ane hombe kupisa kupesana, anogona kumira tembiricha kusvika 315 ° C, haina kukanganiswa nechiedza chezuva, bleach, blecheria, zvipembenene kana alkalis.

Inosimba:Girazi machira vanokanganiswa ne hydrofluorgic acid uye hot phosphoric 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.

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 machira Iva nezvivakwa zvakadai seyakaderera kunyorova, simba rakanyanya, kupisa kupokana uye kuderera dielectric nguva dzose, kuriita kuti varegedze kusimbiswa kwemabhodhi edunhu redunhu uye kusimbisa varnish.
