Iingenelo ezili-10 eziphezulu zeBasalt Fiber

I-Basalt Fiber: Iingenelo ezili-10 eziphezulu

Ifayibha yeBasaltyifayibha yefilamenti eqhubekayo eyenziwe ngendalo Ilitye leBasalt. Ilitye liyanyibilika kwi-1450°C-1500°C lize emva koko litsalwe nge-platinum-rhodium alloy bushing ngesantya esiphezulu. I-fiber ye-basalt ecocekileyo idla ngokuba mdaka. Luhlobo olutsha lwe-fiber engaphiliyo, enobuhlobo nokusingqongileyo, esebenza kakhulu eyenziwe yi-oxides efana ne-silicon dioxide, i-aluminium oxide, i-calcium oxide, i-magnesium oxide, i-iron oxide, kunye ne-titanium dioxide. I-fiber eqhubekayo ye-basalt ayinamandla aphezulu kuphela kodwa ikwaneempawu ezintle ezifana nokufakelwa kombane, ukumelana nokugqwala, kunye nokumelana nobushushu obuphezulu. Ngaphezu koko, inkqubo yayo yemveliso ivelisa inkunkuma encinci kunye nongcoliseko lokusingqongileyo, kwaye imveliso elahliweyo inokonakala ngokwendalo ngaphandle komonakalo, okwenza ibe yinto eluhlaza ngokwenene kwaye inobuhlobo nokusingqongileyo. I-China idwelise i-fiber ye-basalt njengenye yeefayibha ezine ezibalulekileyo zophuhliso (kunye ne-carbon fiber, i-aramid, kunye ne-polyethylene enobunzima obukhulu kakhulu) kwaye iphumelele kwimveliso yemizi-mveliso. I-fiber ye-basalt eqhubekayo ngoku isetyenziswa kakhulu kwii-composites eziqiniswe yi-fiber, izixhobo zokungqubana, ukwakha iinqanawa, ishishini leemoto, kunye nezicelo zobushushu obuphezulu kunye nokukhusela.

1. Izinto ezisetyenziswa gwenxa ezininzi

   Ifayibha yeBasalt yenziwe ngelitye lebasalt, elifumaneka ngobuninzi eMhlabeni naseNyangeni. Oku kugcina iindleko zezinto eziluhlaza ziphantsi.

2. Izinto Ezinobuhlobo Nokusingqongileyo

   I-Basalt Ilitye liyinto yendalo. Inkqubo yalo yokuvelisa ayikhuphi i-boron okanye ezinye ii-alkali metal oxides, ngoko ke uthuli nomsi azinazo izinto eziyingozi kwaye azingcolisi umoya. Le mveliso ikwahlala ixesha elide, nto leyo eyenza ukuba ibe yinto entsha eluhlaza engabizi kakhulu, esebenza kakuhle, kwaye icocekile.

3. Ubushushu obuphezulu kunye nokuxhathisa amanzi

   Iqhubekeka ifayibha yebasalt ingasebenza kubushushu obubanzi obuphakathi kwe -269°C ukuya kwi-700°C (eneqondo lokuthambisa eliyi-960°C). Oku kungcono kune-gifayibha yelass (-60°C ukuya kwi-450°C) kunye ne-carbon fiber (ubuninzi kwi-500°C). Okuphawulekayo kukuba, i-basalt fiber igcina i-80% yamandla ayo okuqala emva kokusebenza kwi-600°C kwaye ayinciphi kwi-860°C. Ikwagcina amandla aphezulu emva kokuvezwa emanzini ashushu angama-70°C.

4. Uzinzo oluGqibeleleyo lweeKhemikhali kunye nokumelana nokugqwala

   Ifayibha yeBasalt iqulethe izinto ezifana neK₂O, MgO, kunye neTiO₂, eziphucula kakhulu ukumelana kwayo nokugqwala kweekhemikhali kunye namanzi. Izinzile ngakumbi kwiikhemikhali kunefayibha yeglasi, ingakumbi kwiindawo ze-alkaline kunye ne-asidi. Ifayibha yeBasalt ibonisa ukumelana okungcono ngakumbi nokugqwala kwe-alkali kwizisombululo zeCa(OH)₂ ezigcweleyo kunye nesamente.

5. I-Modulus ephezulu ye-Elastic kunye ne-Tensile Strength

   I-modulus ye-elastic ye-basalt fiber (9100-11000 kg/mm) iphezulu kune-fiber ye-E-glass, i-asbestos, i-aramid, i-polypropylene, kunye ne-silicon fibers. Amandla ayo okutsalwa (3800-4800 MPa) makhulu kune-fiber ye-carbon ekhuphayo enkulu, i-aramid, i-PBI fiber, i-steel fiber, i-boron fiber, kunye ne-alumina fiber, kwaye iyafana ne-fiber ye-S-glass. Ngobuninzi be-2.65-3.00 g/cm³ kunye nobunzima be-Mohs obuyi-5-9, inika ukumelana nokuguguleka okuhle kunye nokuqina kokutsalwa. Amandla ayo oomatshini adlula kakhulu iifiber zendalo kunye nezokwenziwa, nto leyo eyenza ukuba ibe yinto efanelekileyo yokuqinisa.

6. Ukusebenza Okugqwesileyo Kokugquma Isandi

   I-fiber ye-basalt eqhubekayo ineempawu ezibalaseleyo zokufunxa isandi kunye nengxolo. I-coefficient yayo yokufunxa isandi iyanda kakhulu ngokuphindaphindiweyo. Umzekelo, into efunxa isandi eyenziwe ngeefayibha ze-basalt ezinobubanzi obuyi-1-3 μm (enobunzima obuyi-15 kg/m³ kunye nobukhulu obuyi-30 mm) inee-coefficients zokufunxa isandi eziyi-0.05-0.15 kwi-100-300 Hz, 0.22-0.75 kwi-400-900 Hz, kunye ne-0.85-0.93 kwi-1200-7000 Hz.

7. Iipropati eziBalulekileyo zeDielectric

   Ifayibha yebasalt eqhubekayoUkumelana nomthamo we-'s volume kuphezulu kakhulu kune-E-glass fiber, nto leyo eyinika iipropati ezintle ze-dielectric. Nangona ilitye le-basalt liqulethe phantse i-0.2% ye-conductive oxides, unyango olukhethekileyo lomphezulu olunee-size agents lunokunciphisa i-dielectric loss tangent nge-50% xa kuthelekiswa ne-glass fiber, kwaye ukumelana nomthamo walo kuphezulu.

8. Ukuhambelana kweSilicate yendalo

   Iyasasazeka kakuhle kwaye inamathelana ngokuqinileyo nesamente kunye nekhonkrithi. Ukwanda kwayo kobushushu kunye nee-coefficients zokuqina zihlala zihambelana, kwaye inokumelana okuhle kwemozulu.

9. Ukufunxwa komswakama ophantsi

   I-Basalt fiber inezinga lokufunxwa komswakama elingaphantsi kwe-0.1%, eliphantsi kune-aramid fiber, i-rock wool, kunye ne-asbestos.

10. Ukuqhuba okuphantsi kobushushu

    Ulawulo lobushushu lwe-basalt fiber yi-0.031-0.038 W/m·K, engaphantsi kune-aramid fiber, i-aluminium silicate fiber, i-E-glass fiber, i-rock wool, i-silicon fiber, i-carbon fiber, kunye ne-stainless steel.
