Ubwino 10 Wapamwamba wa Basalt Fiber

Ulusi wa BasaltUbwino 10 Wapamwamba

Ulusi wa basaltndi ulusi wopangidwa ndi ulusi wopitilira wopangidwa kuchokera ku zinthu zachilengedwe Mwala wa Basalt. Mwala umasungunuka pa 1450°C-1500°C kenako umakokedwa kudzera mu platinum-rhodium alloy bushing pa liwiro lalikulu. Ulusi woyera wa basalt nthawi zambiri umakhala wofiirira. Ndi mtundu watsopano wa ulusi wosapangidwa ndi zinthu zachilengedwe, wochezeka ku chilengedwe, wopangidwa ndi ma oxide monga silicon dioxide, aluminium oxide, calcium oxide, magnesium oxide, iron oxide, ndi titanium dioxide. Ulusi wopitilira wa basalt sumangokhala ndi mphamvu zambiri komanso uli ndi zinthu zabwino kwambiri monga kutchinjiriza magetsi, kukana dzimbiri, komanso kukana kutentha kwambiri. Kuphatikiza apo, njira yake yopangira imapanga zinyalala zochepa komanso kuipitsa chilengedwe, ndipo chinthu chomwe chatayidwacho chimatha kuwonongeka mwachilengedwe popanda kuvulaza, zomwe zimapangitsa kuti chikhale chobiriwira komanso chochezeka ku chilengedwe. China yalemba ulusi wa basalt ngati umodzi mwa ulusi wofunikira kwambiri pakukula (pamodzi ndi ulusi wa kaboni, aramid, ndi polyethylene yolemera kwambiri) ndipo yapanga mafakitale. Ulusi wopitilira wa basalt tsopano umagwiritsidwa ntchito kwambiri muzinthu zomangira zolimbikitsidwa ndi ulusi, zida zokangana, zomangamanga zombo, makampani opanga magalimoto, komanso ntchito zoteteza kutentha kwambiri komanso kutentha kwambiri.

1. Zipangizo Zambiri Zopangira

   Ulusi wa basalt umapangidwa kuchokera ku mwala wa basalt, womwe umapezeka kwambiri padziko lapansi komanso mwezi. Izi zimapangitsa kuti zinthu zopangira zikhale zotsika mtengo.

2. Zinthu Zosamalira Chilengedwe

   Basalt Mwala ndi chinthu chachilengedwe. Kupanga kwake sikutulutsa boron kapena ma alkali metal oxides ena, kotero fumbi ndi utsi sizili ndi zinthu zovulaza ndipo sizimaipitsa mlengalenga. Chogulitsachi chimakhala ndi moyo wautali, zomwe zimapangitsa kuti chikhale chotchipa, chogwira ntchito bwino, komanso choyera.

3. Kutentha Kwambiri ndi Kukana Madzi

   Mosalekeza ulusi wa basalt imatha kugwira ntchito kutentha kwakukulu kuyambira -269°C mpaka 700°C (ndi malo ofewa a 960°C). Izi ndi zabwino kuposa gulusi wa lass (-60°C mpaka 450°C) ndi ulusi wa kaboni (wosapitirira 500°C). Chodziwika bwino n'chakuti, ulusi wa basalt umasunga 80% ya mphamvu yake yoyambirira ukagwira ntchito pa 600°C ndipo suchepa pa 860°C. Umasunganso mphamvu kwambiri ukagwiritsidwa ntchito m'madzi otentha a 70°C.

4. Kukhazikika Kwabwino Kwambiri kwa Mankhwala ndi Kukana Kudzimbiri

   Ulusi wa basalt uli ndi zinthu monga K₂O, MgO, ndi TiO₂, zomwe zimathandizira kwambiri kukana kwake ku dzimbiri la mankhwala ndi madzi. Ndi wokhazikika kwambiri pa mankhwala kuposa ulusi wagalasi, makamaka m'malo okhala ndi alkaline ndi acidic. Ulusi wa basalt umawonetsa kukana bwino kwambiri ku dzimbiri la alkali mu njira zodzaza za Ca(OH)₂ ndi simenti.

5. Modulus Yolimba Kwambiri ndi Mphamvu Yolimba

   Ulusi wa basalt (9100-11000 kg/mm) ndi wapamwamba kuposa ulusi wa E-glass, asbestos, aramid, polypropylene, ndi silicon. Mphamvu yake yokoka (3800-4800 MPa) ndi yayikulu kuposa ulusi wa carbon wokoka waukulu, aramid, ulusi wa PBI, ulusi wachitsulo, ulusi wa boron, ndi ulusi wa alumina, ndipo ndi wofanana ndi ulusi wa S-glass. Ndi kuchuluka kwa 2.65-3.00 g/cm³ ndi kuuma kwa Mohs kwa 5-9, imapereka kukana kwabwino kwambiri kovala komanso kulimbitsa kukoka. Mphamvu yake yamakina imaposa ulusi wachilengedwe komanso wopangidwa, zomwe zimapangitsa kuti ikhale chinthu chabwino kwambiri cholimbitsa.

6. Kugwira Ntchito Kwambiri Poteteza Phokoso

   Ulusi wa basalt wopitilira uli ndi mphamvu zabwino kwambiri zoyamwa phokoso ndi phokoso. Mphamvu yake yoyamwa phokoso imawonjezeka kwambiri ndi pafupipafupi. Mwachitsanzo, chinthu choyamwa phokoso chopangidwa ndi ulusi wa basalt wa 1-3 μm m'mimba mwake (wokhala ndi kachulukidwe ka 15 kg/m³ ndi makulidwe a 30 mm) chili ndi mphamvu zoyamwa phokoso za 0.05-0.15 pa 100-300 Hz, 0.22-0.75 pa 400-900 Hz, ndi 0.85-0.93 pa 1200-7000 Hz.

7. Katundu Wodziwika wa Dielectric

   Ulusi wa basalt wopitiliraKukana kwa voliyumu ya magetsi ndi kwakukulu kwambiri kuposa ulusi wa E-glass, zomwe zimapangitsa kuti ikhale ndi mphamvu zabwino kwambiri za dielectric. Ngakhale kuti miyala ya basalt ili ndi ma conductive oxides pafupifupi 0.2%, mankhwala apadera pamwamba pogwiritsa ntchito ma size agents amatha kuchepetsa kutayika kwa dielectric ndi 50% poyerekeza ndi ulusi wagalasi, ndipo kukana kwake kwa voliyumu nakonso n'kokwera.

8. Kugwirizana kwa Silika Yachilengedwe

   Imafalikira bwino ndipo imalumikizana mwamphamvu ndi simenti ndi konkriti. Kuchuluka kwa kutentha ndi kufupika kwake kumakhala kofanana, ndipo imapirira bwino nyengo.

9. Kunyowa Kochepa kwa Chinyezi

   Ulusi wa basalt uli ndi chiŵerengero choyamwa chinyezi chochepera 0.1%, chomwe chili chotsika poyerekeza ndi ulusi wa aramid, ubweya wa miyala, ndi asbestos.

10. Kutentha Kotsika Kwambiri

    Mphamvu ya kutentha ya basalt fiber ndi 0.031-0.038 W/m·K, yomwe ndi yotsika kuposa aramid fiber, aluminiyamu silicate fiber, E-glass fiber, rock weal, silicon fiber, carbon fiber, ndi chitsulo chosapanga dzimbiri.
