Chii chinonzi fiberglass?
Magirazi eFiber anoshandiswa zvakanyanya nekuda kwekushandisa mari shoma uye hunhu hwakanaka, kunyanya muindasitiri yekugadzira zvinhu zvinosanganisa makemikari. Kare muzana remakore rechi18, vanhu vekuEurope vakaona kuti girazi rinogona kurongedzwa kuita machira ekuruka. Magirazi eFiber ane filaments uye mafupi fibers kana flocs. Filaments egirazi anowanzo shandiswa muzvinhu zvinosanganisa makemikari, zvigadzirwa zverabha, mabhandi ekufambisa, matarpaulins, nezvimwewo. Fibers pfupi dzinonyanya kushandiswa muzvinhu zvisina kurukwa, mapurasitiki einjiniya uye zvinhu zvinosanganisa makemikari.
Hunhu hwakanaka hwemagirazi efiberglass uye hwemakanika, nyore kugadzira, uye mutengo wakaderera kana tichienzanisa nekabhoni fiber zvinoita kuti ive chinhu chinosarudzwa pakushandisa zvinhu zvine simba guru. Magirazi efiber anoumbwa nemaoxides e silica. Fiberglass ine hunhu hwakanaka hwemakanika senge kusanyanya kuputsika, simba rakawanda, kuomarara kushoma uye huremu hwakareruka.
Mapolymer akasimbiswa nefiberglass ane mhando dzakasiyana dzefiberglass, dzakadai semafiber enguva refu, fibers dzakachekwa, mat dzakarukwa, uye mat strand dzakachekwa, uye anoshandiswa kuvandudza hunhu hwemakeniki uye tribological hwepolymer composites. Fiberglass inogona kuwana high initial aspect ratios, asi brittleness inogona kukonzera fibers kutyoka panguva yekugadzirisa.
Hunhu hwegirazi refiberglass
Hunhu hukuru hwe fiberglass hunosanganisira zvinhu zvinotevera:
Hazvisi nyore kunwisa mvura: Fiberglass inodzinga mvura uye haina kukodzera mbatya, nekuti ziya harizonyungudike, zvichiita kuti munhu akapfeka anzwe akanyorova; nekuti jira racho harina kukanganiswa nemvura, harizonyungudike.
Kusasimba: Nekuda kwekusasimba, jira harina kusimba zvakanyanya uye harina kusimba zvakanyanya. Saka, rinoda kugadziriswa pamusoro kuti rirambe kukwinya.
Simba Rakanyanya: Fiberglass yakasimba zvikuru, inenge yakasimba seKevlar. Zvisinei, kana shinda dzikakwizana, dzinotyoka uye dzinoita kuti jira riite serakatetepa.
Kudzivirira: Muchidimbu, fiberglass inodzivirira kupisa zvakanaka.
Kugona kudhonzeka: Matayi acho anodhonzeka zvakanaka, zvichiita kuti akwanise kushandiswa pamachira.
Kusapisa: Magirazi anodzivirira kupisa zvakanyanya uye anogona kutsungirira tembiricha inosvika 315°C, haakanganiswa nezuva, bleach, mabhakitiriya, chakuvhuvhu, zvipembenene kana alkalis.
Zvinokanganisa: Fiberglass inokanganiswa ne hydrofluoric acid uye hot phosphoric acid. Sezvo fiber iri chigadzirwa chakagadzirwa negirazi, fiberglass isina kubikwa inofanira kubatwa nokungwarira, senge zvinhu zvinodzivirira imba, nekuti magumo efiber haana kusimba uye anogona kubaya ganda, saka magirovhosi anofanira kupfekwa pakubata fiberglass.
Kushandisa fiberglass
Fiberglass chinhu chisina kuchena chisingatsvi uye chinochengetedza 25% yesimba rayo rekutanga pa540°C. Mazhinji acho haana simba guru pagirazi pafiberglass. Fiber dzisina kuchena hadzizoumbe kana kuora. Fiberglass inokanganiswa ne hydrofluoric acid, hot phosphoric acid nezvimwe zvinhu zvakasimba.
Ichinhu chakanaka kwazvo chinodzivirira kupisa chemagetsi. Jira refaibha rine hunhu hwehunyoro hwakawanda, simba rakawanda, rinonyungudutsa kupisa kwakaderera uye harina dielectric yakawanda, uye chinhu chakakodzera chekusimbisa kudhinda magirazi nemavarnish 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 zvinhu zvemumba, zvinhu zvemitambo, zvemuchadenga, zvemugungwa, zvemagetsi, zvemumba nemhepo.
