Fiberglass ke eng?

Likhoele tsa khalase li sebelisoa haholo ka lebaka la theko e tlaase le thepa e ntle, haholo-holo indastering ea metsoako.Khale koana lekholong la bo18 la lilemo, Maeurope a ile a hlokomela hore khalase e ka ohloa hore e be likhoele bakeng sa ho loha.Lekese la Moemphera oa Fora Napoleon le ne le se le ntse le e-na le masela a khabisitsoeng a entsoeng ka fiberglass.Likhoele tsa khalase li na le likhoele le likhoele tse khutšoane kapa li-flocs.Li-filaments tsa khalase li atisa ho sebelisoa ka thepa e entsoeng ka motsoako, lihlahisoa tsa rabara, mabanta a conveyor, li-tarpaulins, joalo-joalo. Likhoele tse khutšoanyane li sebelisoa haholo-holo ho limmete tse sa lohiloeng, li-plastiki tsa boenjiniere le lisebelisoa tse kopantsoeng.

Glass fiber e na le thepa e ntle ea 'mele le ea mochini, bonolo ba ho qapa, le litšenyehelo tse tlase ha li bapisoa lecarbon fiberetsa hore e be thepa ea boikhethelo bakeng sa lits'ebetso tse kopaneng tsa ts'ebetso e phahameng.Likhoele tsa khalase li entsoe ka li-oxide tsa silica.Likhoele tsa khalase li na le lisebelisoa tse ntle haholo tsa mochini tse joalo ka ho se brittle, matla a phahameng, ho satalla ho tlase le boima bo bobebe.

Khalase ea fiber li-polymers tse matlafalitsoeng li na le sehlopha se seholo sa mefuta e fapaneng ea likhoele tsa khalase, joalo ka likhoele tsa longitudinal,likhoele tse khaotsoeng, meseme e lohiloeng, ledimmete tse sehiloeng, 'me li sebelisetsoa ho ntlafatsa thepa ea mechine le ea tribological ea metsoako ea polymer.Likhoele tsa khalase li ka fihlella likarolo tse phahameng tsa mantlha, empa bofokoli bo ka etsa hore likhoele li robehe nakong ea ts'ebetso.

thepa ea khalase ea fiber

Litšobotsi tse ka sehloohong tsa fiber ea khalase li kenyelletsa lintlha tse latelang:

Ha ho bonolo ho monya metsi:Khalase ea fibere thibela metsi 'me ha e tšoanelehe bakeng sa liaparo, hobane mofufutso o ke ke oa kenngoa, o etsa hore ea apereng a ikutloe a le metsi;hobane thepa ha e amehe ke metsi, e ke ke ea fokotseha.

Inelasticity: Ka lebaka la khaello ea elasticity, lesela le na le ho otlolla ho fokolang le ho hlaphoheloa.Ka hona, ba hloka phekolo ea holim'a metsi ho hanela ho sosobana.

Matla a Phahameng:Fiberglass e matla haholo, e batla e lekana le Kevlar.Leha ho le joalo, ha likhoele li hohlana, lia robeha ’me li etsa hore lesela le be le ponahalo e shaggy.

Insulation: Ka mokhoa o mokhuts'oane oa fiber, fiberglass ke insulator e ntle haholo.

Drability: Likhoele li hohla hantle, li etsa hore e be tse loketseng likharetene.

Ho hanyetsa Mocheso: Lithapo tsa khalase li na le mocheso o phahameng oa mocheso, li ka mamella mocheso ho fihlela ho 315 ° C, ha li amehe ke khanya ea letsatsi, bleach, baktheria, hlobo, likokoanyana kapa alkalis.

E ka etsahala:Likhoele tsa khalase li angoa ke hydrofluoric acid le hot phosphoric acid.Kaha fiber ke sehlahisoa se entsoeng ka khalase, likhoele tse ling tse tala tsa khalase li lokela ho sebetsoa ka hloko, joalo ka lisebelisoa tsa ho roala ka tlung, hobane likhoele tsa fiber li fokola 'me li ka phunya letlalo, kahoo li-gloves li lokela ho apesoa ha u tšoara fiberglass.

Tšebeliso ea fiber ea khalase

Fiberglass ke sesebediswa sa inorganic se sa tjheng mme se boloka hoo e ka bang 25% ya matla a sona a pele ho 540°C.Lik'hemik'hale tse ngata li na le phello e fokolang holim'a likhoele tsa khalase.Inorganic fiberglass e ke ke ea bōptjoa kapa ea senyeha.Likhoele tsa khalase li angoa ke hydrofluoric acid, hot phosphoric acid le lintho tse matla tsa alkaline.

Ke sesebelisoa se setle sa insulating ea motlakase.Masela a fiberglass e na le thepa e kang ho monya mongobo o tlase, matla a phahameng, ho hanyetsa mocheso le ho lula ha dielectric, ho etsa hore e be li-reinforcements tse loketseng bakeng sa liboto tsa potoloho tse hatisitsoeng le li-varnish tse sireletsang.
