Izinzuzo Eziyi-10 Eziphezulu Ze-Basalt Fiber

I-Basalt FiberIzinzuzo Eziyi-10 Eziphezulu

I-Basalt fiberiyi-filament filament eqhubekayo eyenziwe ngemvelo I-Basalt Rock. Idwala liyancibilika ku-1450°C-1500°C bese lidonswa nge-platinum-rhodium alloy bushing ngesivinini esikhulu. I-fiber ye-basalt emsulwa ivame ukuba nsundu. Luhlobo olusha lwe-fiber engaphili, enobungani nemvelo, esebenza kahle kakhulu eyakhiwe ngama-oxide afana ne-silicon dioxide, i-aluminium oxide, i-calcium oxide, i-magnesium oxide, i-iron oxide, kanye ne-titanium dioxide. I-fiber eqhubekayo ye-basalt ayigcini nje ngokuba namandla aphezulu kodwa futhi inezakhiwo ezinhle kakhulu njengokushisa kukagesi, ukumelana nokugqwala, kanye nokumelana nokushisa okuphezulu. Ngaphezu kwalokho, inqubo yayo yokukhiqiza ikhiqiza imfucuza encane kanye nokungcola kwemvelo, futhi umkhiqizo olahliwe ungonakala ngokwemvelo ngaphandle kokulimala, okwenza kube yinto eluhlaza ngempela futhi enobungani nemvelo. I-China ibhale i-fiber ye-basalt njengenye yezintambo ezine ezibalulekile zokuthuthukiswa (kanye ne-carbon fiber, i-aramid, kanye ne-polyethylene enesisindo sama-molecule esiphezulu kakhulu) futhi ifinyelele ekukhiqizweni kwezimboni. I-fiber ye-basalt eqhubekayo manje isetshenziswa kabanzi ezintweni eziqiniswe yi-fiber, izinto zokungqubuzana, ukwakha imikhumbi, imboni yezimoto, kanye nezicelo zokushisa okuphezulu kanye nokuvikela.

1. Izinto Eziningi Zokusetshenziswa

   I-basalt fibre yenziwe ngedwala le-basalt, elitholakala ngobuningi obukhulu eMhlabeni nasenyangeni. Lokhu kugcina izindleko zezinto zokusetshenziswa ziphansi kakhulu.

2. Izinto Ezinobungani Nemvelo

   I-Basalt Idwala liyinto yemvelo. Inqubo yalo yokukhiqiza ayikhiphi i-boron noma amanye ama-alkali metal oxides, ngakho uthuli nentuthu akunazo izinto eziyingozi futhi akungcolisi umkhathi. Lo mkhiqizo futhi uhlala isikhathi eside, okwenza ube yinto entsha eluhlaza engabizi, esebenza kahle kakhulu, futhi ehlanzekile.

3. Izinga Lokushisa Eliphezulu Nokumelana Namanzi

   Okuqhubekayo i-basalt fiber ingasebenza ebangeni elibanzi lokushisa elisukela ku--269°C kuya ku-700°C (enephuzu lokuthambisa elingu-960°C). Lokhu kungcono kune-gi-lass fiber (-60°C kuya ku-450°C) kanye ne-carbon fiber (ubuningi obungu-500°C). Okuphawulekayo ukuthi i-basalt fiber igcina u-80% wamandla ayo okuqala ngemva kokusebenza ku-600°C futhi ayinciphi ku-860°C. Iphinde igcine amandla aphezulu ngemva kokuvezwa emanzini ashisayo angu-70°C.

4. Ukuqina Kwamakhemikhali Okuhle Kakhulu Nokumelana Nokugqwala

   I-Basalt fiber iqukethe izingxenye ezifana ne-K₂O, i-MgO, ne-TiO₂, ezithuthukisa kakhulu ukumelana kwayo nokugqwala kwamakhemikhali namanzi. Izinzile kakhulu ngamakhemikhali kune-glass fiber, ikakhulukazi ezindaweni ezine-alkaline ne-acidic. I-Basalt fiber ikhombisa ukumelana okungcono nakakhulu nokugqwala kwe-alkaline ezixazululweni ze-Ca(OH)₂ ezigcwele kanye nesamente.

5. I-Modulus Enwebeka Kakhulu kanye Nokuqina Kokuqina

   I-modulus ye-elastic ye-basalt fiber (9100-11000 kg/mm) iphakeme kuneye-fiber ye-E-glass, i-asbestos, i-aramid, i-polypropylene, kanye ne-silicon fibers. Amandla ayo okudonsa (3800-4800 MPa) makhulu kune-fiber ye-carbon-tow enkulu, i-aramid, i-fiber ye-PBI, i-fiber yensimbi, i-fiber ye-boron, kanye ne-alumina fiber, futhi ifana ne-fiber ye-S-glass. Ngobuningi obungu-2.65-3.00 g/cm³ kanye nobunzima be-Mohs obungu-5-9, inikeza ukumelana okuhle kakhulu kokuguguleka kanye nokuqinisa ukudonsa. Amandla ayo okusebenza adlula kakhulu imicu yemvelo neyokwenziwa, okwenza kube yinto efanelekile yokuqinisa.

6. Ukusebenza Okuvelele Kokuvimbela Umsindo

   I-fiber ye-basalt eqhubekayo inezakhiwo ezinhle kakhulu zokumunca umsindo nomsindo. I-coefficient yayo yokumunca umsindo iyanda kakhulu ngokuvama. Isibonelo, into emunca umsindo eyenziwe nge-fiber ye-basalt enobubanzi obuyi-1-3 μm (enobukhulu obuyi-15 kg/m³ kanye nobukhulu obuyi-30 mm) ine-coefficients yokumunca umsindo engu-0.05-0.15 ku-100-300 Hz, 0.22-0.75 ku-400-900 Hz, kanye no-0.85-0.93 ku-1200-7000 Hz.

7. Izakhiwo Ezivelele Ze-Dielectric

   I-fiber ye-basalt eqhubekayoUkumelana nomthamo we-'s volume kuphakeme kakhulu kune-E-glass fiber, okwenza kube nezakhiwo ezinhle kakhulu ze-dielectric. Nakuba idwala le-basalt liqukethe cishe ama-oxide aqhubayo angu-0.2%, ukwelashwa okukhethekile kwendawo enama-size agents kunganciphisa i-dielectric loss tangent ngo-50% uma kuqhathaniswa ne-glass fiber, futhi ukumelana nomthamo wayo nakho kuphakeme.

8. Ukuhambisana Kwemvelo Kwe-Silicate

   Ihlakazeka kahle futhi inamathelana ngokuqinile nesamente kanye nokhonkolo. Ukwanda kwayo kokushisa kanye nama-coefficients ayo ahambisanayo, futhi inokumelana okuhle nesimo sezulu.

9. Ukumuncwa Komswakama Ophansi

   I-Basalt fiber inezinga lokumuncwa komswakama elingaphansi kuka-0.1%, elingaphansi kune-aramid fiber, i-rock wool, kanye ne-asbestos.

10. Ukushisa Okuphansi Kokushisa

    Ukushisa kwe-basalt fiber kungu-0.031-0.038 W/m·K, okuphansi kune-aramid fiber, i-aluminium silicate fiber, i-E-glass fiber, uboya bedwala, i-silicon fiber, i-carbon fiber, kanye nensimbi engagqwali.
