Fiberglass e na le melemo e mengata e kang matla a phahameng le boima bo bobebe, ho hanyetsa mafome, ho hanyetsa mocheso o phahameng, le ts'ebetso e ntle ea ho thibela motlakase. Ke e 'ngoe ea thepa e kopaneng e sebelisoang haholo. Ka nako e ts'oanang, Chaena hape ke mohlahisi e moholo ka ho fetisisa lefatšeng oa fiberglass.
1. Fiberglass ke eng?
Fiberglass ke thepa e seng ea tšepe e sa pheleng e nang le ts'ebetso e ntle haholo. Ke minerale ea tlhaho e nang le silika e le thepa e tala ea mantlha, e eketsang lisebelisoa tse tala tsa oxide ea tšepe e itseng. Kamora ho kopanya ka ho lekana, e qhibilihisoa mochesong o phahameng, 'me khalase e qhibilihisitsoeng e phalla ka har'a nozzle e lutlang. , tlas'a ts'ebetso ea matla a ho hula ka lebelo le phahameng, e huloa 'me e pholisoa ka potlako ebe e tiea hore e be likhoele tse ntle haholo tse tsoelang pele.
Bophara ba monofilament ea fiberglass bo tloha ho li-micron tse 'maloa ho isa ho li-micron tse mashome a mabeli, e leng se lekanang le 1/20-1/5 ea moriri. Sehlopha se seng le se seng sa likhoele tsa faeba se entsoe ka li-monofilament tse makholo kapa esita le tse likete.
Litšobotsi tsa motheo tsa fiberglass:
Ponahalo ke sebopeho se kang cylindrical se nang le bokaholimo bo boreleli, karolo e tšekaletseng ke selikalikoe se felletseng, 'me karolo e tšekaletseng e chitja e na le bokhoni bo matla ba ho jara mojaro; khanyetso ea khase le metsi e fetang e nyane, empa bokaholimo bo boreleli bo etsa hore matla a ho kopana ha faeba a be manyane, e leng se sa lumellaneng le motsoako le resin; bongata ka kakaretso bo ka har'a 2.50-2.70 g/cm3, haholo-holo ho itšetlehile ka sebopeho sa khalase; matla a ho tsikinyeha a phahame ho feta likhoele tse ling tsa tlhaho le likhoele tsa maiketsetso; thepa e robehang habonolo, bolelele ba eona ha e robeha bo bonyenyane haholo; khanyetso ea metsi le khanyetso ea asiti li betere, ha khanyetso ea alkali e le tlase haholo. Phapang.
2. Tlhophiso eafaebakhalase
Ho tloha sehlopheng sa bolelele, e ka aroloa ka fiberglass e tsoelang pele, fiberglass e khutšoanyane (fiberglass e bolelele bo tsitsitseng) le fiberglass e telele (LFT).
3. Tšebeliso ea fiberglass
Fiberglass e na le matla a ho thapolla a phahameng, modulus e phahameng ea ho tenyetseha, ho se chese, ho hanyetsa lik'hemik'hale, ho monya metsi hanyane, le ts'ebetso e ntle ea ts'ebetso. , e sebelisoa haholo masimong a fapaneng.
Fiberglass ea kantle ho naha e arotsoe ka mekhahlelo e mene ho latela tšebeliso ea sehlahisoa: thepa ea ho matlafatsa bakeng sa polasetiki ea thermosetting e matlafalitsoeng, thepa ea ho matlafatsa fiberglass bakeng sa thermoplastics, thepa ea ho matlafatsa samente ea gypsum, thepa ea masela ea fiberglass, eo ho eona thepa ea ho matlafatsa e etsang 70-75%, thepa ea masela ea fiberglass e etsang 25-30%. Ho latela tlhoko e tlase, meralo ea motheo e etsa hoo e ka bang 38% (ho kenyeletsoa liphaephe, ho tlosa letsoai metsing a leoatle, ho futhumatsa ntlo le ho thibela metsi, paballo ea metsi, jj.), lipalangoang li etsa hoo e ka bang 27-28% (likepe, likoloi, terene e lebelo le phahameng, jj.), 'me lisebelisoa tsa elektroniki li etsa hoo e ka bang 17%.
Ka bokhutšoanyane, masimo a ts'ebeliso ea fiberglass ka kakaretso a kenyelletsa lipalangoang, thepa ea kaho, indasteri ea motlakase, indasteri ea mechini, indasteri ea peterole, setso sa boikhathollo le theknoloji ea ts'ireletso ea naha.
