Malingana ndi mawonekedwe ndi kutalika, galasi la galasi likhoza kugawidwa muzitsulo zopitirira, utali wokhazikika ndi ubweya wagalasi;malinga ndi kapangidwe ka galasi, imatha kugawidwa kukhala yopanda alkali, kukana kwamankhwala, alkali wapakatikati, mphamvu yayikulu, zotanuka modulus komanso kukana kwa alkali (alkali resistance) fiberglass, etc.
Zida zazikulu zopangira magalasi opanga magalasi ndi: mchenga wa quartz, alumina ndi pyrophyllite, miyala yamchere, dolomite, boric acid, phulusa la soda, mirabilite, fluorite, etc. Njira zopangira zimagawidwa m'magulu awiri: imodzi ndiyo kupanga galasi losungunuka. mu ulusi;china ndicho kupanga magalasi osungunuka kukhala mipira yagalasi kapena ndodo zokhala ndi mainchesi 20 mm, ndiyeno kutentha ndi kusungunula m'njira zosiyanasiyana kupanga mipira yagalasi kapena ndodo zokhala ndi mainchesi 3 mpaka 3 mm.80μm ulusi wabwino kwambiri.Ulusi wautali wopandamalire wokokedwa ndi njira yojambulira zamakina a platinamu alloy plates amatchedwa ulusi wagalasi wosalekeza, womwe umadziwika kuti ulusi wautali.Ulusi wolekanitsidwa wopangidwa ndi odzigudubuza kapena kutuluka kwa mpweya, wotchedwa fixed-length glass fibers, womwe umadziwika kuti ulusi wamfupi.
Ulusi wagalasi amagawidwa m'magulu osiyanasiyana malinga ndi kapangidwe kake, katundu ndi ntchito.Malinga ndi malamulo a kalasi yokhazikika, Ulusi wagalasi wa E-grade amagwiritsidwa ntchito kwambiri komanso amagwiritsidwa ntchito kwambiri pazida zotchingira magetsi;S-grade ndi fiber yapadera.
Galasi yomwe imagwiritsidwa ntchito popanga fiberglass ndi yosiyana ndi magalasi omwe amagwiritsidwa ntchito pazinthu zina zamagalasi.Nthawi zambiri, magalasi opangira ulusi omwe adagulitsidwa ndi awa:
Mphamvu yayikulu komanso magalasi apamwamba a fiberglass modulus
Amadziwika ndi mphamvu zapamwamba komanso modulus yapamwamba.Mphamvu yake yokhazikika ya fiber imodzi ndi 2800MPa, yomwe ili pafupifupi 25% kuposa ya galasi yopanda alkali, ndipo modulus yake yotanuka ndi 86000MPa, yomwe ndi yokwera kuposa E-glass fiber.Zogulitsa za FRP zomwe zimapangidwa nawo zimagwiritsidwa ntchito kwambiri m'makampani ankhondo, zakuthambo, njanji yothamanga kwambiri, mphamvu yamphepo, zida zoteteza zipolopolo ndi zida zamasewera.
AR fiberglass
Imadziwikanso kuti CHIKWANGWANI chagalasi chosamva alkali, CHIKWANGWANI chagalasi chosamva alkali ndi chinthu cholimbitsa konkriti yagalasi (simenti) (yotchedwa GRC), ulusi wokhazikika kwambiri, komanso cholowa m'malo mwa chitsulo ndi asibesitosi m'malo omwe si. -zigawo za simenti zonyamula katundu.Makhalidwe a ulusi wamagalasi osamva alkali ndi abwino kukana kwa alkali, amatha kukana kukokoloka kwa zinthu zambiri zamchere mu simenti, mphamvu yogwira mwamphamvu, modulus zotanuka kwambiri, kukana, kulimba komanso kupindika, kusayaka, kukana chisanu, kutentha. -kusagwirizana, kusinthasintha kwamphamvu kwa chinyezi, kukana kung'amba bwino komanso kusasunthika, mawonekedwe amphamvu, kuumba kosavuta, etc., ulusi wagalasi wosagwira alkali ndi mtundu watsopano wolimbikitsira wobiriwira komanso wokonda zachilengedwe womwe umagwiritsidwa ntchito kwambiri polimbitsa konkriti (simenti) Zida .
D galasi
Imadziwikanso kuti magalasi otsika a dielectric, amagwiritsidwa ntchito popanga ulusi wagalasi wa dielectric wokhala ndi mphamvu yabwino ya dielectric.
Kuphatikiza pazigawo zagalasi zomwe zili pamwambapa, ulusi watsopano wagalasi wopanda mchere wa alkali tsopano ukupezeka, womwe ulibe boroni, potero umachepetsa kuipitsidwa kwa chilengedwe, koma mphamvu zake zotchingira magetsi ndi zida zamakina ndizofanana ndi galasi lakale la E.Kuphatikiza apo, pali ulusi wagalasi wokhala ndi magalasi awiri, omwe amagwiritsidwa ntchito popanga ubweya wagalasi, komanso akuti ali ndi kuthekera kolimbitsa magalasi a fiberglass.Kuphatikiza apo, pali ulusi wagalasi wopanda fluorine, womwe ndi ulusi wagalasi wopanda mchere wopangidwa kuti uziteteza chilengedwe.

Mutha kugawa magalasi a fiberglass m'magulu osiyanasiyana, kutengera zida zomwe zimagwiritsidwa ntchito komanso kuchuluka kwake.
Nayi mitundu 7 yosiyanasiyana ya magalasi a fiberglass ndikugwiritsa ntchito pazinthu zatsiku ndi tsiku:
Galasi la alkali (A-glass)
Soda galasi kapena soda laimu galasi.Ndilo mtundu wa fiberglass womwe umagwiritsidwa ntchito kwambiri.Magalasi a alkali amakhala pafupifupi 90% ya magalasi onse opangidwa.Ndiwo mtundu wofala kwambiri ndipo umagwiritsidwa ntchito popanga zotengera zamagalasi, monga zitini ndi mabotolo a chakudya ndi zakumwa, ndi magalasi a pawindo.
Ziwiya zophikira zopangidwa ndi galasi la soda ndi chitsanzo chabwino cha galasi A.Ndi yotsika mtengo, yotheka kwambiri, komanso yovuta.Ulusi wagalasi wamtundu wa A ukhoza kusungunukanso ndi kufewetsanso kangapo ndipo ndi mitundu yabwino yagalasi yobwezeretsanso magalasi.
Magalasi osamva alkali AE-glass kapena AR-glass
Galasi la AE kapena AR limayimira galasi losamva alkali, lomwe limagwiritsidwa ntchito ngati konkriti.Ndi chinthu chopangidwa ndi zirconia.
Kuwonjezera kwa zirconia, mchere wovuta, wosatentha kutentha, kumapangitsa kuti galasi la fiberglass likhale loyenera kugwiritsidwa ntchito mu konkire.Galasi la AR limalepheretsa kusweka kwa konkriti popereka mphamvu komanso kusinthasintha.Komanso, mosiyana ndi chitsulo, sichichita dzimbiri mosavuta.
Galasi la Chemical
Magalasi a C kapena magalasi a mankhwala amagwiritsidwa ntchito ngati minofu yakunja kwa mapaipi ndi zida zosungira madzi ndi mankhwala.Chifukwa cha kuchuluka kwa calcium borosilicate yomwe imagwiritsidwa ntchito popanga magalasi, imawonetsa kukana kwa mankhwala m'malo owononga.
Magalasi a C-galasi amasunga bwino mankhwala ndi kapangidwe kake m'malo aliwonse ndipo samamva bwino ndi mankhwala amchere.
Dielectric galasi
Ulusi wagalasi wa Dielectric (D-glass) amagwiritsidwa ntchito kwambiri pazida zamagetsi, zophikira, ndi zina zotero.Ndi mtundu wabwino wa fiberglass chifukwa cha kuchepa kwake kwa dielectric.Izi ndichifukwa cha kukhalapo kwa boron trioxide mu kapangidwe kake.
Galasi lamagetsi
E-glass kapena E-fiberglass nsalu ndi muyezo wamakampani womwe umapereka malire pakati pa magwiridwe antchito ndi mtengo.Ndi zinthu zopepuka zophatikizika zomwe zimagwiritsidwa ntchito muzamlengalenga, zam'madzi ndi mafakitale.Katundu wa magalasi a E-magalasi ngati chitsulo cholimbitsa chapangitsa kuti ikhale yokondedwa kwambiri ndi zinthu zamalonda monga zobzala, mabwato osambira, ndi mabwato.
E-magalasi mu ulusi wa ubweya wagalasi amatha kupangidwa kukhala mawonekedwe kapena kukula kulikonse pogwiritsa ntchito njira yosavuta yopangira.Popanga zisanachitike, zinthu za E-glass fiber zimapangitsa kuti zikhale zoyera komanso zotetezeka kugwira ntchito.
Magalasi apangidwe
Magalasi opangidwa (S glass) amadziwika chifukwa cha makina ake.Mayina amalonda a R-glass, S-glass ndi T-glass onse amatanthauza mtundu womwewo wa fiberglass.Poyerekeza ndi E-glass fiber, ili ndi mphamvu zolimba kwambiri komanso modulus.Fiberglass iyi idapangidwa kuti igwiritsidwe ntchito m'mafakitale oteteza komanso oyendetsa ndege.
Amagwiritsidwanso ntchito popanga zida zolimba za ballistic.Chifukwa mtundu wagalasi wagalasi umagwira ntchito kwambiri, umangogwiritsidwa ntchito m'mafakitale apadera okhala ndi ma voliyumu ochepa opanga.Zimatanthauzanso kuti S-glass ikhoza kukhala yokwera mtengo.
Advantex fiberglass
Mtundu uwu wa fiberglass umagwiritsidwa ntchito kwambiri m'mafakitale amafuta, gasi ndi migodi, komanso m'mafakitale amagetsi ndi ntchito zam'madzi (machitidwe ochotsa zonyansa ndi zonyansa).Zimaphatikiza mawotchi ndi magetsi a E-glass ndi kukana kwa dzimbiri kwa asidi E, C, R mtundu wa magalasi ulusi.Amagwiritsidwa ntchito m'malo omwe zomanga zimakhala zosavuta kuchita dzimbiri.
