Ulusi wa basalt ndi ulusi wosapangidwa ndi zinthu zachilengedwe wopangidwa makamaka kuchokera ku miyala yachilengedwe ya basalt. Umakonzedwa kudzera mu njira zosungunula ndi kukoka kutentha kwambiri, zomwe zimapangitsa kuti pakhale mankhwala ndi zinthu zakuthupi zokhazikika. Ulusi uwu umagwiritsidwa ntchito m'magawo osiyanasiyana, womwe umadziwika ndi gwero lake lochuluka la zinthu zopangira komanso njira yosavuta yopangira.

Pofuna kupititsa patsogolo zomangamanga zokhazikika, mapeti opangidwa ndi ulusi wa basalt omwe amagwira ntchito bwino kwambiri asankhidwa kuti akwaniritse zofunikira kwambiri pakusintha madoko ku Europe konse. Opangidwa kuti akwaniritse zofunikira kwambiri za uinjiniya wa m'mphepete mwa nyanja ndi m'madzi, ma geotextiles atsopano a basalt a 750 g/m² ndi 950 g/m² akukonzanso kulimba ndi kulimba kwa chilengedwe pakugwiritsa ntchito kwambiri geotechnical.

Basalt ndi yofala kwambiri ndipo ndi yotsika mtengo m'dziko langa. Mtengo wake wopanga ulusi ndi wotsika, ndipo uli ndi ubwino waukulu poyerekeza ndi ulusi wa mankhwala, ulusi wa kaboni, ndi ulusi wagalasi. Ili ndi kuthekera kwakukulu pamsika ndipo ndi mtundu watsopano wa chinthu chaukadaulo wapamwamba komanso chamtengo wapatali chowonjezera nthawi yatsopano.

Ulusi wa basalt siwokhazikika pa mphamvu zokha, wokhazikika pa kutentha, wopirira kuwonongeka kwa malo olumikizirana, komanso sungawonongeke kwambiri komanso wokhazikika pa kukangana, komanso uli ndi mtengo woyenera. Kugwiritsa ntchito ulusi wa basalt kuzinthu zolimbitsa kukangana sikuti kumawonjezera moyo ndi kutentha kwa zinthu zokangana zamagalimoto, komanso kumathetsa zinthu zosiyanasiyana zosasangalatsa pazida zokangana zamakono, zomwe zimathandiza kuthetsa vuto la kutha kwa kutentha m'mabuleki achikhalidwe amagalimoto, potero kuchepetsa ngozi zamagalimoto.

Ulusi wa basalt, monga ulusi wobiriwira wachilengedwe, umapangidwa kuchokera ku basalt wachilengedwe kudzera mu kusungunuka. Uli ndi ubwino wapadera monga kuchepa kwa mpweya, kusamala chilengedwe, kupepuka, kukana nyengo, komanso mphamvu zabwino kwambiri zamakanika. Pambuyo pa kusintha kwa zinthu zosiyanasiyana komanso kupanga njira zatsopano, wapeza ntchito yayikulu m'munda wa zipangizo zamakabati zamagalimoto, kusintha makina a kabati kuchokera ku mitundu yosiyanasiyana ya kuteteza chilengedwe, magwiridwe antchito, ndi mtengo wake, ndikuyika mphamvu yayikulu pakuyenda kwa mpweya wotsika.

Ulusi wa basalt wachilengedwe komanso wopanda poizoni umapangidwa mwa kusungunula ndi kukoka miyala yamoto. Kuti apange ulusi wa basalt, miyala ya basalt imatenthedwa kufika pafupifupi 1500°C isanakokedwe mu ulusi wopitilira kudzera mu platinum-rhodium alloy spinnerets.

Ulusi wa Basalt wosapindika Nsalu ndi nsalu yopyapyala yolukidwa kuchokera ku ulusi wa basalt wosapindika (wosapindika kapena wopindika pang'ono) pogwiritsa ntchito mapangidwe osavuta monga osalala ndi opindika. Phindu lake lalikulu lili pakusunga bwino mphamvu zamakina ndi magwiridwe antchito a ulusi wa basalt kudzera mu kapangidwe ka "kupindika kochepa + kupitirira kwapamwamba," zomwe zimapangitsa kuti ikhale gawo labwino kwambiri lolimbitsa zinthu zophatikizika.

Ulusi wa basalt umagwiritsidwa ntchito mwamphamvu. Ndiye, kodi ulusi wa basalt umapangidwa bwanji? Ndi ulusi wopitilira womwe umapangidwa ndi kujambula mwachangu kwa zinthu za miyala ya basalt pambuyo poti zasungunuka pa 1450°C mpaka 1500°C kudzera mu platinum-rhodium alloy spinneret. Ulusi wa basalt ndi wabulauni kapena wagolide. Ulusi wa basalt ndi mtundu watsopano wa ulusi wosapangidwa ndi zinthu zachilengedwe, wosamalira chilengedwe, wobiriwira, komanso wothandiza kwambiri. Ndi chinthu chatsopano cha m'zaka za zana la 21 chomwe ndi chobiriwira, chosamalira chilengedwe, komanso chosadetsa, ndipo ndi chimodzi mwa ulusi waukulu anayi wa ku China wothandiza kwambiri. Ulusi wa basalt umasonyeza makhalidwe abwino kwambiri pankhani ya mphamvu, kukana kutentha kwambiri ndi kotsika, kukana dzimbiri, kutchinjiriza kutentha, kutchinjiriza mawu, kuletsa moto, komanso kutchinjiriza mankhwala ndi magetsi.

Pepala lofufuzira lotchedwa “Hierarchical basalt metayarn for ergonomic protective space textiles” linasindikizidwa mu magazini ya Matter ndi gulu la Pulofesa Xia Zhigang ndi Academician Xu Weilin ochokera ku National Key Laboratory of New Textile Materials and Advanced Processing ku Wuhan Textile University, mogwirizana ndi Pulofesa Tao Guangming.

Ulusi wa basalt sumangokhala ndi mphamvu zambiri, kukhazikika bwino kwa kutentha, kukana kuwonongeka ndi zinthu zina, kutopa kochepa, komanso mitengo yokhazikika ya kukangana, komanso ndi mitengo yoyenera. Kugwiritsa ntchito ulusi wa basalt muzinthu zowonjezera kukangana kumapindulitsa pakuwonjezera nthawi ya moyo wa zipangizo zokangana zamagalimoto komanso kukonza kutentha kwawo kogwirira ntchito. Ikhozanso kuthetsa zovuta zosiyanasiyana zomwe zilipo za zipangizo zamakono zokangana, zomwe zimathandiza kuthana ndi vuto la kutentha komwe kumachepa m'mabuleki achikhalidwe amagalimoto, potero kuchepetsa kuchuluka kwa ngozi zapamsewu.
