Zatsopano zobiriwira zobiriwira zowoneka bwino za Basalt Fiber

Kodi Basalt Fiber ndi chiyani?
Ulusi wa Basalt ndi ulusi wosalekeza wopangidwa ndi miyala yachilengedwe ya basalt monga zida zazikulu.Ikasungunuka pa 1450-1500 ℃, imakokedwa ndi platinamu-rhodium alloy kujambula bushing pa liwiro lalikulu.Mtundu wake nthawi zambiri umakhala wofiirira ndipo umakhala ndi chitsulo chonyezimira.Zimapangidwa ndi oxides monga silicon dioxide, aluminium oxide, calcium oxide, magnesium oxide, iron oxide ndi titaniyamu woipa.CHIKWANGWANI cha Basalt chili ndi zinthu zambiri zabwino kwambiri monga kulimba kwambiri, kutchinjiriza kwa magetsi, kukana dzimbiri, kukana kutentha kwambiri, kukana kukalamba, ndi zina zambiri, ndipo chimagwirizana bwino ndi chilengedwe ndipo sichimatulutsa kuipitsidwa kwachiwiri.Choncho, ndi zoona zobiriwira mkulu-ntchito zatsopano zoteteza chilengedwe.
dziko langa latchula ulusi wa basalt ngati umodzi mwa ulusi waukulu zinayi (carbon fiber, aramid fiber, ultra-high molecular weight polyethylene, basalt fiber) kuti apange chitukuko chachikulu.Zosowa za ndege ndi magawo ena ali ndi chiyembekezo chogwiritsa ntchito.
Njira yopanga basalt fiber
Mwala wachilengedwe wa basalt wopangidwa ndi kuphulika kwa chiphala chamoto umagwiritsidwa ntchito ngati zopangira, kuphwanyidwa ndikuyika mung'anjo yosungunuka, kutenthedwa mpaka 1450 ~ 1500 ° C, ndipo amakokedwa mwachangu kudzera pa waya wa platinamu-rhodium alloy zojambulajambula, ndi ulusi wa basalt. amapangidwa motere.
Mwachidule, njira yopangira ulusi wa basalt ndi "kukoka" mwala wolimba wa volcanic basalt mu silika pa kutentha kwakukulu.
Kutalika kwa ulusi wa basalt wopangidwa ndiukadaulo womwe ulipo ukhoza kufika 6 ~ 13μm, womwe ndi woonda kuposa tsitsi.
Kapangidwe kake kakuwoneka mu chithunzi pansipa.

Magma osungunuka

Kujambula
Monga amorphous inorganic silicate substance, basalt fiber imakhala ndi nthawi yochepa yopanga, njira yosavuta, yopanda madzi otayira m'mafakitale ndi mpweya wotayirira, komanso mtengo wowonjezera.Imadziwika kuti "green material" m'zaka za zana la 21.

Kuchita bwino kwa basalt fiber
Ulusi woyera wa basalt wokhazikika wachilengedwe umakhala wagolide ndipo umawoneka ngati masilinda osalala okhala ndi gawo lozungulira lozungulira.CHIKWANGWANI cha Basalt chimakhala ndi kachulukidwe kwambiri komanso kuuma kwambiri, chifukwa chake chimakhala ndi kukana kwamphamvu kwambiri komanso kulimba kwamphamvu.Ulusi wa Basalt ndi chinthu cha amorphous, ndipo kutentha kwake kwa utumiki kumakhala -269 ~ 700 ° C (kufewa ndi 960 ° C).Ndi asidi ndi alkali kugonjetsedwa, ali ndi mphamvu UV kukana, otsika hygroscopicity, ndi bwino kukana chilengedwe.Kuphatikiza apo, ili ndi maubwino a kutchinjiriza kwabwino, kusefa kwa kutentha kwambiri, kukana ma radiation ndi permeability yabwino ya mafunde, kukhazikika kwamphamvu kwamafuta, ukhondo wa chilengedwe komanso chiŵerengero chabwino kwambiri cha magwiridwe antchito ndi mawonekedwe ake.

Zokwanira zopangira
Ulusi wa Basalt umapangidwa pojambula pambuyo posungunula miyala ya basalt, ndipo nkhokwe za basalt ore padziko lapansi ndi mwezi ndizowona, ndipo mtengo wazinthu zopangira ndi wotsika kwambiri.
Zida Zosamalidwa ndi Malo
Basalt ore ndi zinthu zachilengedwe, palibe boron kapena zitsulo zina zamchere zamchere zomwe zimatulutsidwa panthawi yopanga, kotero palibe zinthu zovulaza zomwe zimatenthedwa muutsi ndi fumbi, ndipo sizidzawononga mlengalenga.Kuphatikiza apo, mankhwalawa amakhala ndi moyo wautali wautumiki, motero ndi mtundu watsopano wazinthu zobiriwira zoteteza zachilengedwe zotsika mtengo, magwiridwe antchito apamwamba komanso ukhondo wabwino.
Kutentha kwakukulu ndi kukana madzi
Opaleshoni kutentha osiyanasiyana CHIKWANGWANI mosalekeza basalt zambiri -269 ~ 700 ° C (kufewetsa mfundo ndi 960 ° C), pamene wa galasi CHIKWANGWANI ndi -60 ~ 450 ° C, ndi pazipita ntchito kutentha kwa mpweya CHIKWANGWANI angafikire 500. °C.Makamaka pamene fiber ya basalt imagwira ntchito pa 600 ° C, mphamvu yake pambuyo pa kusweka imatha kusunga 80% ya mphamvu zake zoyambirira;ikamagwira ntchito pa 860 ° C popanda kuchepa, ngakhale ubweya wa mchere wokhala ndi kukana kwambiri kutentha ukhoza kukhalabe panthawiyi mphamvu pambuyo pa kusweka.50% -60%, ubweya wagalasi wawonongeka kwathunthu.Mpweya wa carbon umatulutsa CO ndi CO2 pafupifupi 300 ° C.Ulusi wa Basalt ukhoza kukhala ndi mphamvu zambiri pansi pa madzi otentha pa 70 ° C, ndipo ulusi wa basalt ukhoza kutaya mphamvu yawo pambuyo pa 1200 h.
Kukhazikika kwamankhwala abwino komanso kukana dzimbiri
Chingwe chosalekeza cha basalt chimakhala ndi zinthu monga K2O, MgO) ndi TiO2, ndipo zigawozi ndizopindulitsa kwambiri pakuwongolera kukana kwa dzimbiri kwamankhwala komanso kusagwira madzi kwa fiber, ndipo zimagwira ntchito yofunika kwambiri.Poyerekeza ndi kukhazikika kwa mankhwala a galasi fiber, ili ndi ubwino wambiri, makamaka muzofalitsa zamchere ndi acidic.CHIKWANGWANI cha Basalt chimathanso kukhalabe ndi kukana kwambiri munjira yodzaza ya Ca (OH) 2 ndi media zamchere monga simenti.Alkali dzimbiri katundu.
High modulus ya elasticity ndi kulimba mphamvu
The elastic modulus ya basalt fiber ndi: 9100 kg/mm-11000 kg/mm, yomwe ndi yapamwamba kuposa ya alkali-free glass fiber, asbestos, aramid fiber, polypropylene fiber ndi silicon fiber.Mphamvu yamphamvu ya basalt fiber ndi 3800-4800 MPa, yomwe ili yokwera kuposa ya carbon fiber, aramid, PBI fiber, chitsulo, boron, ndi alumina fiber, ndipo ikufanana ndi S glass fiber.CHIKWANGWANI cha Basalt chili ndi kachulukidwe ka 2.65-3.00 g/cm3 komanso kulimba kwakukulu kwa 5-9 pa sikelo ya Mohs, motero imakhala yolimba kwambiri komanso yolimba.Mphamvu zake zamakina zimaposa kwambiri ulusi wachilengedwe ndi ulusi wopangidwa, motero ndizomwe zimalimbitsa bwino, ndipo zida zake zabwino kwambiri zamakina zili patsogolo pazingwe zinayi zogwira ntchito kwambiri.
Zabwino kwambiri zotsekera mawu
Ulusi wosalekeza wa basalt uli ndi kutsekereza kwamawu komanso kutulutsa mawu.Zitha kudziwika kuchokera ku mphamvu ya mayamwidwe a ulusi pamayendedwe osiyanasiyana kuti mayamwidwe ake amakokedwe amawu amawonjezeka kwambiri pamene ma frequency akuwonjezeka.Mwachitsanzo, ngati zasankhidwa zoyamwitsa mawu zopangidwa ndi basalt CHIKWANGWANI ndi awiri a 1-3μm (kachulukidwe 15 kg/m3, makulidwe 30mm) CHIKWANGWANI si kuonongeka pansi chikhalidwe Audio pafupipafupi 100-300 Hz. , 400-900 Hz ndi 1200-7 000 HZ.Ma coefficients amayamwidwe a zida ndi 0. 05 ~ 0.15, 0. 22 ~ 0.75 ndi 0.85 ~ 0.93, motsatana.
Zabwino Kwambiri za Dielectric
Voliyumu resistivity ya basalt fiber mosalekeza ndi dongosolo la kukula kwake kuposa la E glass fiber, ndipo ili ndi katundu wabwino wa dielectric.Ngakhale miyala ya basalt imakhala ndi oxide conductive yomwe ili ndi gawo lalikulu la pafupifupi 0.2, pambuyo pa chithandizo chapadera chapamwamba chapadera ndi chonyowetsa chapadera, tangent ya dielectric ya basalt fiber ndi 50% yotsika kuposa ya fiber glass, ndi mphamvu ya resistivity ya fiber. ndipamwambanso kuposa ulusi wagalasi.
Kugwirizana kwachilengedwe kwa silicate
Ili ndi kubalalitsidwa kwabwino ndi simenti ndi konkriti, mphamvu yomangirira yolimba, kukulitsa kwamafuta kosasinthasintha ndi kutsika kokwanira, komanso kukana kwanyengo.
Low hygroscopicity
The hygroscopicity ya basalt fiber ndi yocheperapo 0.1%, yomwe ndi yotsika kuposa ya aramid fiber, rock ubweya ndi asibesitosi.
Low matenthedwe madutsidwe
Thermal conductivity ya basalt fiber ndi 0.031 W/m·K -0.038 W/m·K, yomwe ndi yotsika kuposa ya aramid fiber, aluminiyamu silicate fiber, ulusi wagalasi wopanda alkali, ubweya wa miyala, silicon fiber, kaboni fiber ndi zosapanga dzimbiri. zitsulo.
Poyerekeza ndi ulusi wina, ulusi wa basalt umagwira ntchito bwino pazinthu zambiri.
