Chii chinonzi fiberglass?
Fiberglass inoshandiswa zvakanyanya nekuda kwemitengo-inoshanda uye yakanaka zvivakwa, kunyanya muindasitiri yecomposites.Kare muzana remakore rechi18, vanhu vokuEurope vakaziva kuti girazi raigona kusonwa kuita shinda dzokuruka.Fiberglass ine zvese filaments uye mapfupi fiber kana flocs.Girazi filaments inowanzoshandiswa muzvinhu zvakaumbwa, zvigadzirwa zverabha, mabhandi ekufambisa, tarpaulins, nezvimwewo. Mafiinzi mapfupi anonyanya kushandiswa mune zvisiri zvakarukwa, mapurasitiki einjiniya uye zvinhu zvinoumbwa.
Fiberglass 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.Fiberglass ine yakanakisa mechanicha zvimiro senge kusanyanya brittle, kusimba kwepamusoro, kuderera kuomarara uye kureruka huremu.
Fiberglass yakasimbiswa mapolymers ane kirasi hombe yemhando dzakasiyana dzefiberglass, senge longitudinal faibha, akachekwa mafiber, akarukwa mateti, uye akachekwa tambo mats, uye anoshandiswa kuvandudza michina uye tribological zvimiro zvepolymer composites.Fiberglass inogona kuwana yakakwira yekutanga chimiro ratios, asi brittleness inogona kukonzera mafiber kutyoka panguva yekugadziriswa.
Fiberglass properties
Hunhu hukuru hwefiberglass hunosanganisira zvinotevera zvinhu:
Hazvisi nyore kutora mvura: Fiberglass inodzivirira mvura uye haina kukodzera zvipfeko, nokuti jira harizopiwi, zvichiita kuti mutakuri anzwe akanyorova;nokuti zvinhu hazvina kukanganiswa nemvura, hazvizodzike.
Inelasticity: Nekuda kwekushaikwa kwekunyorova, jira rine kushoma kwekuzvarwa kutambanudza uye kupora.Naizvozvo, ivo 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 fibre fomu, fiberglass insulator yakanaka kwazvo.
Drapability: Mafibhi anodonhedza zvakanaka, achiita kuti ave akanakira maketeni.
Heat Resistance: Girazi fibers inodzivirira kupisa kwakanyanya uye inogona kumira kutonhora kusvika ku315 ° C, haibatsirwi nechiedza chezuva, bleach, mabhakitiriya, mold, tumbuyu kana alkalis.
Inobatwa: Fiberglass inobatwa nehydrofluoric acid uye inopisa phosphoric acid.Sezvo fiber iri chigadzirwa chegirazi, imwe fiberglass yakasvibirira inofanira kubatwa nekuchenjerera, semidziyo yekudzivirira yeimba, nokuti fiber inopera haina kusimba uye inogona kubaya ganda, saka magirovhosi anofanira kupfekwa kana uchibata fiberglass.
Kushandiswa kwefiberglass
Fiberglass inorganic material isingapise uye inoramba iine 25% yesimba rayo rekutanga pa540°C.Mazhinji ane diki girazi mhedzisiro pane fiberglass.Inorganic fibers haigoni kuumba kana kuparara.Fiberglass inobatwa nehydrofluoric acid, hot phosphoric acid uye zvinhu zvakasimba.
Iyo yakanakisa magetsi insulating material.Iyo fiber jira ine hunhu hwehunyoro hwepamusoro, kusimba kwepamusoro, kupisa kwakadzika kunyura uye yakaderera dielectric kugara, uye ndiyo yakanaka yekusimbisa zvinhu zvekudhinda magirazi egirazi 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 vemo, zvinhu zvemitambo, aerospace, marine, zvemagetsi, Kumba uye simba remhepo.
