Basalt Fiber
Ulusi wa Basalt ndi ulusi wosalekeza wochokera ku basalt wachilengedwe. Ndi mwala wa basalt mu 1450 ℃ ~ 1500 ℃ utasungunuka, kudzera pa platinamu-rhodium alloy wire chojambulira chotulutsa mbale yothamanga kwambiri yopangidwa ndi ulusi wopitilira. Mtundu wa ulusi woyera wa basalt wachilengedwe nthawi zambiri umakhala wofiirira. Basalt CHIKWANGWANI ndi mtundu watsopano wa inorganic zachilengedwe wochezeka wobiriwira mkulu-ntchito CHIKWANGWANI zakuthupi, amene wapangidwa silika, aluminiyamu, calcium okusayidi, magnesium okusayidi, okusayidi chitsulo ndi titaniyamu woipa ndi oxides ena.Basalt mosalekeza CHIKWANGWANIosati ali ndi mphamvu zambiri, komanso ali ndi zinthu zosiyanasiyana zabwino kwambiri monga kutchinjiriza magetsi, kukana dzimbiri, kukana kutentha kwambiri ndi zina zotero. Kuonjezera apo, kupanga makina a basalt fiber adaganiza zopanga zinyalala zochepa, kuipitsa pang'ono kwa chilengedwe, ndipo mankhwalawa akhoza kuonongeka mwachindunji m'chilengedwe pambuyo pa zinyalala, popanda kuvulaza, kotero ndi zobiriwira zenizeni, zowononga zachilengedwe. Ulusi wosalekeza wa Basalt wakhala ukugwiritsidwa ntchito kwambiri muzophatikizira zolimbitsa ulusi, zida zokangana, zida zomangira zombo, zida zotchingira kutentha, makampani amagalimoto, nsalu zosefera zotentha kwambiri, komanso minda yoteteza.
Makhalidwe
① Zipangizo zokwanira
Basalt fiberamapangidwa ndi basalt ore kusungunuka ndi kukokedwa, ndipo basalt ore Padziko Lapansi ndi mwezi ndi ndithu nkhokwe nkhokwe, kuchokera zopangira ndalama ndi otsika.
② Zinthu zoteteza chilengedwe
Basalt ore ndi zinthu zachilengedwe, palibe boron kapena zitsulo zina zamchere zomwe zimatulutsidwa panthawi yopanga, kotero palibe zinthu zovulaza zomwe zimatuluka muutsi, mlengalenga sichidzayambitsa kuipitsa. Kuphatikiza apo, mankhwalawa amakhala ndi moyo wautali, motero ndi mtundu watsopano wazinthu zobiriwira zoteteza zachilengedwe zotsika mtengo, magwiridwe antchito apamwamba komanso ukhondo wabwino.
③ Kutentha kwakukulu ndi kukana madzi
Kusalekeza basalt CHIKWANGWANI ntchito kutentha osiyanasiyana zambiri 269 ~ 700 ℃ (kufewetsa mfundo 960 ℃), pamene CHIKWANGWANI galasi kwa 60 ~ 450 ℃, kutentha kwambiri mpweya CHIKWANGWANI angafikire 500 ℃. Makamaka, basalt CHIKWANGWANI mu 600 ℃ ntchito, mphamvu pambuyo yopuma akhoza kukhalabe 80% ya mphamvu yapachiyambi; ntchito pa 860 ℃ popanda shrinkage, ngakhale kutentha kukana zabwino mchere ubweya pa nthawi yopuma akhoza anakhalabe pa 50% -60%, magalasi ubweya kotheratu. Mpweya wa carbon pafupifupi 300 ℃ pakupanga CO ndi CO2. Basalt CHIKWANGWANI pa 70 ℃ pansi zochita za madzi otentha akhoza kukhalabe mphamvu, basalt CHIKWANGWANI mu 1200 h akhoza kutaya mbali ya mphamvu.
④ Kukhazikika kwamankhwala abwino komanso kukana dzimbiri
Kusalekeza basalt CHIKWANGWANI lili K2O, MgO) ndi TiO2 ndi zigawo zina, ndipo zigawo zikuluzikulu kuti kusintha kukana mankhwala dzimbiri CHIKWANGWANI ndi ntchito madzi ndi opindulitsa kwambiri, ndi mbali yofunika kwambiri. Ndizopindulitsa kwambiri poyerekeza ndi kukhazikika kwa mankhwala a ulusi wa galasi, makamaka muzochita zamchere ndi za acidic zoonekeratu za ulusi wa basalt muzitsulo zodzaza Ca (OH) 2 ndi simenti ndi zina zamchere zamchere zimatha kukhalabe kukana kwakukulu kwa ntchito ya dzimbiri yamchere.

⑤ High modulus ya elasticity ndi kulimba mphamvu
The modulus of elasticity of basalt fiber ndi 9100 kg/mm-11000 kg/mm, yomwe ndi yapamwamba kuposa ya alkali-free glass fiber, asbestos, aramid fiber, polypropylene fiber ndi silica fiber. Kulimba kwamphamvu kwa basalt fiber ndi 3800-4800 MPa, yomwe ndi yokwera kuposa ya tow carbon fiber, aramid fiber, PBI fiber, chitsulo, boron, 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 madigiri 5-9 pa sikelo ya kuuma kwa Mohs, motero chimakhala ndi kukana kwabwino kwa abrasion komanso kulimbitsa mphamvu. Mphamvu zake zamakina zimaposa kwambiri ulusi wachilengedwe ndi ulusi wopangidwa, motero ndizomwe zimalimbitsa bwino, ndipo zida zake zabwino kwambiri zamakina zili patsogolo pazigawo zinayi zazikulu zogwira ntchito kwambiri.
⑥ Kuchita bwino kwambiri kotsekereza mawu
Ulusi wopitilira wa basalt umakhala ndi kutsekereza kwamawu, kutulutsa mawu, kuchokera ku fiber mumitundu yosiyanasiyana ya mayamwidwe amawu kumatha kuphunziridwa, ndi kuchuluka kwa ma frequency, mayamwidwe ake amawu amawonjezeka kwambiri. Monga kusankha kwa m'mimba mwake 1-3μm basalt CHIKWANGWANI chopangidwa ndi (kachulukidwe 15 kg/m3, makulidwe a 30mm) zida zoyamwitsa mawu, muzomvera za 100-300 Hz, 400-900 Hz ndi 1200-7,000 HZ, mikhalidwe ya fiber material ~ 010. 0.22 ~ 0.75 ndi 0.85 ~ 0.93, motero.
⑦ Zodziwika bwino za dielectric
Voliyumu resistivity ya basalt fiber mosalekeza ndi dongosolo limodzi la ukulu kuposa laE glass fiber, yomwe ili ndi mphamvu zabwino kwambiri za dielectric. Ngakhale miyala ya basalt ili ndi gawo lalikulu la pafupifupi 0,2 la oxides conductive, koma kugwiritsa ntchito mankhwala apadera olowetsera apadera pamwamba, basalt fiber dielectric mowa ngongole ya tangent kuposa ulusi wamagalasi ndi 50% m'munsi, kuchuluka kwa resistivity kwa CHIKWANGWANI ndikwapamwamba kuposa ulusi wagalasi.

⑧ Kugwirizana kwachilengedwe kwa silicate
Kubalalitsidwa kwabwino ndi simenti ndi konkriti, kulumikiza mwamphamvu, kokwanira kofananira kwakukula kwamafuta ndi kutsika, kukana kwanyengo yabwino.
⑨ Kuchepetsa kuyamwa kwa chinyezi
Mayamwidwe a chinyontho cha basalt fiber ndi ochepera 0.1%, otsika kuposa ulusi wa aramid, ubweya wa miyala ndi asibesitosi.
⑩ Kutsika kwa matenthedwe
Thermal conductivity ya basalt fiber ndi 0.031 W / mK - 0.038 W / mK, yomwe ndi yotsika kuposa ya aramid fiber, alumino-silicate fiber, alkali-free glass fiber, rockwool, silicon fiber, carbon fiber ndi chitsulo chosapanga dzimbiri.

Fiberglass
Fiberglass, zinthu zopanda zitsulo zopanda zitsulo zomwe zimagwira ntchito bwino, zili ndi zabwino zambiri monga kutchinjiriza bwino, kukana kutentha, kukana kwa dzimbiri, mphamvu zamakina apamwamba, koma choyipa chake ndi chosalimba komanso chosakanizidwa ndi abrasion. Zimatengera chlorite, mchenga wa quartz, miyala yamchere, dolomite, miyala ya boron calcium, miyala ya boron magnesium mitundu isanu ndi umodzi ya ores monga zopangira ndi kutentha kwambiri kusungunuka, kujambula, kupindika, kuluka ndi njira zina popanga makulidwe ake a monofilament kwa ma microns angapo mpaka ma microns oposa 20, ofanana ndi 1/5, 20 bundle imodzi ya tsitsi. mazana kapena masauzande a monofilament.Fiberglassnthawi zambiri amagwiritsidwa ntchito ngati zida zolimbikitsira muzinthu zophatikizika, zida zotchinjiriza zamagetsi ndi zida zotenthetsera matenthedwe, matabwa ozungulira ndi madera ena achuma cha dziko.

Zinthu Zakuthupi
Kusungunuka: galasi ndi mtundu wa sanali crystalline, palibe malo osungunuka, amakhulupirira kuti kufewetsa mfundo 500 ~ 750 ℃.
Malo otentha: pafupifupi 1000 ℃
Kachulukidwe: 2.4 ~ 2.76 g/cm3
Ulusi wagalasi ukagwiritsidwa ntchito ngati zolimbikitsira mapulasitiki olimbikitsidwa, chinthu chachikulu ndikulimba kwake. Kulimba kwamphamvu mumkhalidwe wokhazikika ndi 6.3 ~ 6.9 g / d, kunyowa 5.4 ~ 5.8 g / d. Kutentha kwa kutentha ndikwabwino, kutentha mpaka 300 ℃ popanda mphamvu. Ili ndi zotchingira bwino kwambiri zamagetsi, ndi zida zapamwamba zamagetsi zamagetsi, zomwe zimagwiritsidwanso ntchito popanga zida ndi zida zotchingira moto. Nthawi zambiri zimangowonongeka ndi alkali, hydrofluoric acid ndi phosphoric acid.
