Ubwino 10 Wapamwamba wa Basalt Fiber

Basalt Fiber: Ubwino 10 Wapamwamba

Basalt fiberndi ulusi wosalekeza wopangidwa kuchokera ku chilengedwe Basalt Rock. Mwalawu umasungunuka pa 1450 ° C-1500 ° C ndipo kenako amakokedwa kupyolera mu platinamu-rhodium alloy bushing pa liwiro lalikulu. Ulusi woyera wa basalt nthawi zambiri umakhala wofiirira. Ndi mtundu watsopano wa inorganic, eco-friendly, high-performance fiber wopangidwa ndi oxides monga silicon dioxide, aluminium oxide, calcium oxide, magnesium oxide, iron oxide, ndi titanium dioxide. Ulusi wopitilira wa Basalt sikuti uli ndi mphamvu zambiri komanso umakhala ndi zinthu zabwino kwambiri monga kutsekereza magetsi, kukana dzimbiri, komanso kukana kutentha kwambiri. Kuphatikiza apo, kupanga kwake kumatulutsa zinyalala zochepa komanso kuwononga chilengedwe, ndipo zinthu zomwe zatayidwa zimatha kuipitsidwa mwachilengedwe popanda kuvulaza, ndikupangitsa kuti ikhale yobiriwira komanso yokoma zachilengedwe. China yatchula ulusi wa basalt ngati imodzi mwazinthu zinayi zazikuluzikulu zachitukuko (pamodzi ndi mpweya wa carbon, aramid, ndi polyethylene yapamwamba kwambiri ya molekyulu) ndipo yakwanitsa kupanga mafakitale. Ulusi wosalekeza wa basalt tsopano umagwiritsidwa ntchito kwambiri mumagulu opangidwa ndi fiber-reinforced, friction materials, shipbuilding, makampani oyendetsa galimoto, ndi kutentha kwambiri ndi ntchito zoteteza.

1. Zopangira Zambiri

   Ulusi wa Basalt umapangidwa kuchokera ku thanthwe la basalt, lomwe limapezeka mochuluka kwambiri padziko lapansi ndi mwezi. Izi zimapangitsa kuti mtengo wazinthu zopangira ukhale wotsika.

2. Eco-Friendly Material

   Basalt thanthwe ndi zinthu zachilengedwe. Kapangidwe kake sikutulutsa boron kapena ma alkali metal oxides, motero fumbi ndi utsi sizikhala ndi zinthu zovulaza ndipo siziipitsa mpweya. Zogulitsazo zimakhalanso ndi moyo wautali, zomwe zimapangitsa kuti zikhale zotsika mtengo, zogwira ntchito kwambiri, komanso zoyera zatsopano zobiriwira.

3. Kutentha Kwambiri ndi Kukaniza Madzi

   Zopitilira basalt fiber imatha kugwira ntchito pa kutentha kwakukulu kwa -269 ° C mpaka 700 ° C (ndi malo ochepetsetsa a 960 ° C). Izi ndizoposa gmchere wa fiber (-60 ° C mpaka 450 ° C) ndi carbon fiber (max 500 ° C). Makamaka, ulusi wa basalt umakhalabe ndi 80% ya mphamvu yake yoyambirira itatha kugwira ntchito pa 600 ° C ndipo simachepera pa 860 ° C. Imakhalanso ndi mphamvu zambiri pambuyo poyatsidwa ndi madzi otentha a 70 ° C.

4. Kukhazikika Kwabwino Kwambiri kwa Chemical ndi Kukaniza kwa Corrosion

   Ulusi wa Basalt uli ndi zinthu monga K₂O, MgO, ndi TiO₂, zomwe zimathandizira kwambiri kukana kwa dzimbiri ndi madzi. Ndiwokhazikika pamankhwala kuposa ulusi wagalasi, makamaka m'malo amchere ndi acidic. CHIKWANGWANI cha Basalt chimawonetsa kukana kwabwinoko ku dzimbiri za alkali mu mayankho odzaza a Ca(OH) ₂ ndi simenti.

5. High Elastic Modulus ndi Kulimba Kwamphamvu

   Basalt fiber's elastic modulus (9100-11000 kg/mm) ndi yapamwamba kuposa ya E-glass fiber, asbestos, aramid, polypropylene, ndi silicon fibers. Mphamvu yake yokhazikika (3800-4800 MPa) ndi yaikulu kuposa ya carbon-tow fiber, aramid, PBI fiber, fiber fiber, boron fiber, ndi alumina fiber, ndipo ikufanana ndi S-glass fiber. Ndi kachulukidwe ka 2.65-3.00 g/cm³ ndi kuuma kwa Mohs kwa 5-9, kumapereka kukana kovala bwino komanso kulimbikitsa mwamphamvu. Mphamvu yake yamakina imaposa ulusi wachilengedwe komanso wopangidwa, zomwe zimapangitsa kuti ikhale yolimba kwambiri.

6. Kuchita Kwabwino Kwambiri kwa Sound Insulation

   Ulusi wosalekeza wa basalt uli ndi mawu abwino kwambiri komanso mayamwidwe a phokoso. Mayamwidwe ake amawu amawonjezeka kwambiri ndi pafupipafupi. Mwachitsanzo, chinthu choyamwa phokoso chopangidwa ndi 1-3 μm m'mimba mwake ulusi wa basalt (wokhala ndi makulidwe a 15 kg/m³ ndi makulidwe a 30 mm) imakhala ndi ma coefficients omveka a 0.05-0.15 pa 100-300 Hz, 0.22-0.75 pa 0.22-0.75 pa 040 Hz. 1200-7000 Hz.

7. Zodziwika bwino za Dielectric Properties

   Kusalekeza basalt CHIKWANGWANI's volume resistivity ndi dongosolo la kukula kwake kuposa E-glass fiber, zomwe zimapatsa mphamvu za dielectric. Ngakhale thanthwe la basalt lili ndi pafupifupi 0.2% conductive oxides, chithandizo chapadera chapamtunda chokhala ndi ma saiziing amatha kuchepetsa kutayika kwa dielectric ndi 50% poyerekeza ndi ulusi wamagalasi, ndipo mphamvu yake yolimbana nayo ndiyokwera kwambiri.

8. Kugwirizana kwachilengedwe kwa silicate

   Imabalalitsa bwino ndikumangirira mwamphamvu ndi simenti ndi konkriti. Kukula kwake kwamafuta ndi ma coefficients ocheperako ndi ofanana, ndipo imakhala ndi kukana kwanyengo yabwino.

9. Kuchepa kwa Chinyezi

   Chingwe cha Basalt chimakhala ndi chinyontho chochepera 0.1%, chomwe ndi chotsika kuposa ulusi wa aramid, ubweya wa miyala, ndi asibesitosi.

10. Low Thermal Conductivity

    Basalt fiber's thermal conductivity ndi 0.031-0.038 W/m·K, yomwe ndi yotsika kuposa fiber aramid, aluminiyamu silicate fiber, E-glass fiber, rock wool, silicon fiber, carbon fiber, ndi chitsulo chosapanga dzimbiri.
