Sebopeho le thepa ea fiber ea khalase

Khalase e sebelisoang ho hlahisa fiber ea khalase e fapane le ea lihlahisoa tse ling tsa khalase. Khalase e sebelisoang bakeng sa likhoele tse rekisoang lefatšeng e na le silika, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, joalo-joalo ho ea ka litaba tsa alkali ka khalase, e ka aroloa ka fiber ea khalase e sa lefelloeng ea alkali. (sodium oxide 0% ~ 2%, ea khalase ea aluminium borosilicate) le fiber ea khalase ea alkali e mahareng (sodium oxide 8% ~ 12%), Ke ea khalase ea sodium calcium silicate e nang le kapa ntle le boron) le fiber e phahameng ea alkali ea khalase (e fetang 13% sodium oxide ke ea sodium calcium silicate khalase).

1. Khalase ea E, e tsejoang hape e le khalase e sa lefelloeng ea alkali, ke khalase ea borosilicate. Karolo e sebelisoang ka ho fetisisa ea khalase bakeng sa fiber ea khalase e na le lisebelisoa tse ntle tsa motlakase le thepa ea mochine. E sebelisoa haholo ho hlahisa fiber ea khalase bakeng sa ho kenya motlakase le fiber ea khalase bakeng sa FRP. Bothata ba eona ke hore ho bonolo ho senngoa ke asiti ea inorganic, ka hona ha e loketse tikoloho ea acid.

2. C-khalase, e tsejoang hape e le khalase ea alkali e mahareng, e tšoauoa ka khanyetso e ntle ea lik'hemik'hale, haholo-holo ho hanyetsa acid, ho feta khalase e seng alkali, empa ts'ebetso e mpe ea motlakase le 10% ~ 20% matla a tlase a mochini ho feta fiber e seng alkali khalase. Ka kakaretso, fiber ea khalase ea alkali ea kantle e na le tekanyo e itseng ea boron trioxide, athe fiber ea khalase ea alkali ea China ha e na boron ho hang. Linaheng tse ling, fiber ea khalase ea alkali e bohareng e sebelisoa feela ho hlahisa lihlahisoa tsa khalase tse sa jeng, tse kang khalase ea fiber surface e ikutloang, hape e sebelisoa ho matlafatsa thepa ea marulelo a asphalt. Leha ho le joalo, Chaena, fiber ea khalase ea alkali e bohareng e nka karolo e fetang halofo (60%) ea tlhahiso ea fiber ea khalase 'me e sebelisoa haholo ho matlafatsa FRP le tlhahiso ea lesela le tlamang, Hobane theko ea eona e ka tlaase ho moo. ea alkali free glass fiber, e na le tlholisano e matla.

3. Matla a phahameng a khalase ea fiber e khetholloa ke matla a phahameng le modulus e phahameng. Matla a eona a nang le fiber e le 'ngoe ke 2800mpa, e ka bang 25% e phahameng ho feta ea alkali free glass fiber,' me modulus ea eona ea elastic ke 86000mpa, e phahameng ho feta ea E-glass fiber. Lihlahisoa tsa FRP tse hlahisoang ke bona li sebelisoa haholo indastering ea sesole, sebaka, lihlomo tse thibelang likulo le lisebelisoa tsa lipapali. Leha ho le joalo, ka lebaka la theko e phahameng, e ke ke ea tuma ts'ebelisong ea sechaba, 'me tlhahiso ea lefats'e e ka ba lithane tse likete.

4. Ar glass fiber, e tsejoang hape e le alkali resistant glass fiber, haholo-holo e ntshetswa pele ho matlafatsa samente.

5. Khalase, e tsejoang hape e le khalase e phahameng ea alkali, ke khalase e tloaelehileng ea silicate ea sodium. Ha se hangata e sebelisetsoang ho hlahisa fiber ea khalase ka lebaka la ho se khone ho thibela metsi.

6. Khalase ea E-CR ke khalase e ntlafalitsoeng ea boron le alkali, e sebelisetsoang ho hlahisa fiber ea khalase e nang le acid e ntle le ho hanyetsa metsi. Ho hanyetsa metsi a eona ke makhetlo a 7 ~ 8 ho feta a alkali free glass fiber, 'me ho hanyetsa ha eona ha acid ho molemo ho feta ha fiber ea khalase ea alkali e mahareng. Ke mofuta o mocha o etselitsoeng liphaephe tse ka tlas'a lefatše le litanka tsa polokelo.

7. Khalase ea D, e tsejoang hape e le khalase e tlaase ea dielectric, e sebelisetsoa ho hlahisa likhoele tse tlaase tsa khalase ea dielectric ka matla a matla a dielectric.

Ho phaella ho likarolo tse ka holimo tsa khalase ea fiber, ho hlahile fiber e ncha ea alkali e sa lefelloeng ea khalase lilemong tsa morao tjena. Ha e na boron ho hang, e le ho fokotsa tšilafalo ea tikoloho, empa thepa ea eona ea motlakase le lisebelisoa tsa mechine li tšoana le tsa khalase ea E ea setso. Ho phaella moo, ho na le mofuta oa fiber ea khalase e nang le likarolo tse peli tsa khalase, e 'nileng ea sebelisoa ho hlahisa boea ba khalase. Ho boleloa hore e boetse e na le monyetla oa ho matlafatsa FRP. Ho feta moo, ho na le fiber ea khalase e se nang fluorine, e leng fiber ea khalase e sa lefelloeng ea alkali e ntlafalitsoeng bakeng sa litlhoko tsa ts'ireletso ea tikoloho.
