I-10 ephezulu yezinto ezilungileyo ze-Basalt Fiber

IFayibha yeBasalt: Izinto ezili-10 eziluncedo

I-basalt fiberyintsinga yefilament eqhubekayo eyenziwe ngendalo Basalt Rock. Ilitye liyanyibilika kwi-1450 ° C-1500 ° C kwaye emva koko litsalwe nge-platinum-rhodium alloy bushing ngesantya esiphezulu. I-basalt fiber ecocekileyo idla ngokuba mdaka. Ludidi olutsha lwe-inorganic, eco-friendly, ifayibha yokusebenza ephezulu eyenziwe ngeeoksidi ezifana nesilicon dioxide, i-aluminiyam oxide, i-calcium oxide, i-magnesium oxide, i-iron oxide, kunye ne-titanium dioxide. Ifayibha eqhubekayo ye-Basalt ayinawo amandla aphezulu kuphela kodwa ikwaqhayisa ngeepropathi ezigqwesileyo ezinje ngokufakelwa kombane, ukuxhathisa ukubola, kunye nokumelana nobushushu obuphezulu. Ngaphaya koko, inkqubo yayo yokuvelisa ivelisa inkunkuma encinci kunye nokungcoliseka kwendalo, kwaye imveliso elahliweyo inokuthotywa ngokwemvelo ngaphandle kokulimala, iyenze ibe yinto eluhlaza ngokwenene kunye ne-eco-friendly. I-China idwelise i-basalt fiber njengenye yeentsinga ezine eziphambili zophuhliso (kunye ne-carbon fiber, i-aramid, kunye ne-ultra-high molecular weight polyethylene) kwaye iphumelele imveliso yezoshishino. Ifayibha ye-basalt eqhubekayo ngoku isetyenziswa ngokubanzi kwi-fiber-reinforced composite, izinto ezixutywayo, ukwakhiwa kweenqanawa, imboni yemoto, kunye nokushisa okuphezulu kunye nokukhusela izicelo.

1. IiMathiriyeli ezikrwada ezininzi

   Ifayibha ye-basalt yenziwe kwilitye le-basalt, elifumaneka ngobuninzi obubalulekileyo kuMhlaba kunye nenyanga. Oku kugcina iindleko zemathiriyeli ekrwada zisezantsi noko.

2. I-Eco-Friendly Material

   Ibasalt ilitye yinto yendalo. Inkqubo yayo yokuvelisa ayikhuphi i-boron okanye ezinye ii-alkali zentsimbi oxides, ngoko ke uthuli nomsi azinazinto eziyingozi kwaye azingcolisi umoya. Imveliso nayo inobomi obude, okwenza ibe yindleko ephantsi, intsebenzo ephezulu, kunye nokucoca izinto ezintsha eziluhlaza.

3. Ubushushu obuphezulu kunye nokumelana naManzi

   Ngokuqhubekayo i-basalt fiber inokusebenza kuluhlu olubanzi lobushushu obuphakathi kwe -269°C ukuya kuma-700°C (enendawo yokuthamba eyi-960°C). Oku kungaphezulu kune-gifayibha (-60 ° C ukuya ku-450 ° C) kunye ne-carbon fiber (max 500 ° C). Ngokucacileyo, i-basalt fiber igcina i-80% yamandla ayo okuqala emva kokusebenza kwi-600 ° C kwaye ayincitshi kwi-860 ° C. Ikwagcina amandla aphezulu emva kokuvezwa kumanzi ashushu angama-70°C.

4. Uzinzo olugqwesileyo lweMichiza kunye noKuchasana nokuRhwalala

   I-Basalt fiber iqulethe amacandelo afana ne-K₂O, i-MgO, kunye ne-TiO₂, ephucula kakhulu ukuchasana kwayo nemichiza yokubola kunye namanzi. Izinzile ngokwekhemikhali kunefibre yeglasi, ngakumbi kwindawo ene-alkaline kunye ne-asidi. Ifayibha ye-Basalt ibonisa ukuxhathisa okungcono kwi-alkali corrosion kwi-saturated Ca (OH) ₂ isisombululo kunye nesamente.

5. Imodyuli ephezulu ye-Elastic kunye namandla okuqina

   I-Basalt fiber's elastic modulus (9100-11000 kg/mm) iphezulu kune-E-glass fiber, asbestos, aramid, polypropylene, kunye ne-silicon fibers. Amandla ayo obunzima (3800-4800 MPa) inkulu kune-fiber ye-carbon fiber, i-aramid, i-PBI fiber, i-fiber yensimbi, i-boron fiber, kunye ne-alumina fiber, kwaye ifaniswa ne-S-glass fiber. Ngoxinaniso lwe-2.65-3.00 g/cm³ kunye nobunzima be-Mohs be-5-9, inika ukuxhathisa okugqwesileyo kunye nokuqiniswa kokuqina. Amandla ayo omatshini ayodlula lee imicu yendalo kunye neyokwenziwa, nto leyo eyenza ibe yeyona nto ifanelekileyo yokuqinisa.

6. Ukusebenza okugqwesileyo kwezandi zokugquma

   Ifayibha ye-basalt eqhubekayo inesandi esihle kunye neempawu zokufunxa ingxolo. Isandi sayo sokufunxa i-coefficient yonyuka kakhulu ngokuphindaphindiweyo. Ngokomzekelo, isandi esifunxa isandi esenziwe nge-1-3 μm ububanzi be-basalt fibers (enoxinano lwe-15 kg/m³ kunye nobukhulu be-30 mm) ine-coefficients yokufunxa isandi se-0.05-0.15 kwi-100-300 Hz, 0.22-0.75 kunye ne-500 kwi-Hz 40. 1200-7000 Hz.

7. IiPropati zeDielectric eziBalulekileyo

   I-basalt fiber eqhubekayo's umthamo resistivity lulandelelwano ngokobukhulu ngaphezulu kune-E-glass ifayibha, inika iipropati ezibalaseleyo dielectric. Nangona ilitye le-basalt liqulethe phantse i-0.2% yee-oxides eziqhubayo, unyango olukhethekileyo lomphezulu oluneejenti zokulinganisa lunokunciphisa ilahleko ye-dielectric nge-50% xa kuthelekiswa nefayibha yeglasi, kwaye umthamo wayo wokumelana nawo uphezulu.

8. Ukuhambelana kweSilicate yendalo

   Isasaza kakuhle kwaye ibophe ngamandla ngesamente kunye nekhonkrithi. Ukwandiswa kwayo kwe-thermal kunye ne-contraction coefficients iyahambelana, kwaye inokumelana nemozulu elungileyo.

9. Ukufunxa ukufuma okuphantsi

   Ifayibha ye-basalt inezinga lokufunxa ukufuma ngaphantsi kwe-0.1%, engaphantsi kunefayibha ye-aramid, uboya bamatye, kunye ne-asbestos.

10. I-Thermal Conductivity ephantsi

    I-Basalt fiber's conductivity ye-thermal conductivity 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 nensimbi engenasici.
