Basalt Fiber
Basalt faibha inoramba iine faibha inotorwa kubva kune yakasikwa basalt. Ibwe rebasalt mu1450 ℃ ~ 1500 ℃ mushure mekunyunguduka, kuburikidza neplatinamu-rhodium alloy waya yekudhirowa leakage plate yakakwirira-kumhanya kudhonza yakagadzirwa neinoenderera fiber. Rudzi rwemhando yakachena yebasalt fiber kazhinji ine brown. Basalt faibha rudzi rutsva rwezvakatipoteredza zvine hushamwari zvakasvibira yakakwirira-inoshanda fiber zvinhu, iyo inoumbwa nesilika, alumina, calcium oxide, magnesium oxide, iron oxide uye titanium dioxide uye mamwe maokisi.Basalt inoenderera fiberkwete chete ine simba repamusoro, asi zvakare ine zvakasiyana-siyana zvemhando yepamusoro senge magetsi ekudzivirira, corrosion resistance, high temperature resistance and so. Mukuwedzera, nzira yekugadzirwa kwebasalt fiber yakasarudza kubudisa tsvina shoma, kusvibiswa kuduku kune zvakatipoteredza, uye chigadzirwa chacho chinogona kusvibiswa zvakananga mumamiriro ezvinhu mushure memarara, pasina kukuvadza, saka ndeyechokwadi yakasvibirira, inochengetedza zvakatipoteredza zvinhu. Basalt inoenderera mberi fibers yakashandiswa zvakanyanya mufiber-yakasimbiswa composites, friction materials, shipbuilding materials, heat-insulating materials, indasitiri yemotokari, high-temperature filtration machira, uye minda yekudzivirira.
Hunhu
① Zvigadzirwa zvakakwana
Basalt fiberinogadzirwa ne basalt ore yakanyungudutswa uye yakadhonzwa, uye basalt ore paPasi nemwedzi inzvimbo dzakachengeterwa chinangwa, kubva pamitengo yezvinhu zvakadzikira.
② zvinhu zvine hushamwari zvakatipoteredza
Basalt ore chinhu chechisikigo, hapana boron kana imwe alkali simbi oxides inoburitswa panguva yekugadzira, saka hapana zvinhu zvinokuvadza zvinonaya muutsi, mhepo haizokonzere kusvibiswa. Uyezve, chigadzirwa chine hupenyu hurefu, saka irwo rudzi rutsva rwegirinhi inoshanda yekudzivirira nharaunda ine mutengo wakaderera, kuita kwepamusoro uye kuchena kwakanaka.
③ Kupisa kwakanyanya uye kuramba kwemvura
Inoenderera mberi basalt fiber inoshanda tembiricha yemhando inowanzo 269 ~ 700 ℃ (kupfavisa poindi ye960 ℃), nepo girazi faibha ye60 ~ 450 ℃, tembiricha yepamusoro yekabhoni fiber inogona kungosvika 500 ℃. Kunyanya, basalt fiber mu600 ℃ basa, simba rayo mushure mekuputika rinogona kuramba richichengetedza 80% yesimba rekutanga; shanda pa860 ℃ pasina shrinkage, kunyange kana kupisa kwekushisa kweakanakisa mineral wool panguva ino mushure mekuputika kunogona kungochengetwa pa50% -60%, girazi remvere rinoparadzwa zvachose. Carbon fiber inosvika mazana matatu ℃ pane CO uye CO2 kugadzirwa. Basalt fiber pa70 ℃ pasi pekuita kwemvura inopisa inogona kuchengetedza simba rakakwirira, basalt fiber mu1200 h inogona kurasikirwa nechikamu chesimba.
④ Kugadzikana kwakanaka kwemakemikari uye kusagadzikana kwemarara
Inoenderera mberi basalt fiber ine K2O, MgO) uye TiO2 uye zvimwe zvikamu, uye izvi zvikamu zvekuvandudza kemikari corrosion kuramba kwefiber uye kushanda kwemvura kunobatsira zvakanyanya, inoita basa rakakosha. Zvinonyanya kubatsira kana zvichienzaniswa nekemikari kugadzikana kwegirazi fibers, kunyanya mualkaline uye acidic media zvakanyanya pachena basalt fibers mune yakazara Ca (OH) 2 mhinduro uye simende uye mamwe alkaline midhiya inogonawo kuchengetedza yakakwirira kuramba kune alkali corrosion performance.

⑤ Yakakwirira modulus ye elasticity uye kusimba simba
Iyo modulus ye elasticity yebasalt fiber ndeye 9100 kg/mm-11000 kg/mm, iyo yakakwirira kudarika yealkali-isina girazi fiber, asbestos, aramid fiber, polypropylene fiber uye silica fiber. Kusimba kwesimba rebasalt fiber i3800-4800 MPa, iyo yakakwirira kupfuura iyo hombe kabhoni fiber, aramid fiber, PBI fiber, simbi fiber, boron fiber, alumina fiber, uye inofananidzwa neS girazi fiber. Basalt faibha ine density ye2.65-3.00 g/cm3 uye kuomarara kwakanyanya kwemadhigirii 5-9 pachikero chekuomarara kweMohs, saka ine yakanakisa abrasion resistance uye tensile reinforcement properties. Simba rayo remuchina rinopfuura iro remafibhi echisikigo uye mafibhi ekugadzira, saka chinhu chakakodzera chekusimbisa, uye hunyanzvi hwayo hwemakinari huri kumberi kune ina huru-yepamusoro-inoshanda fiber.
⑥ Yakanakisa ruzha rwekudzivirira kuita
Inoenderera mberi basalt fiber ine yakanakisa kuvharidzira ruzha, kuita kwekurira kwekuita, kubva pafayibha mune akasiyana odhiyo ruzha absorption coefficient inogona kudzidzwa, nekuwedzera kweiyo frequency, yayo inonzwika kunyura coefficient inowedzera zvakanyanya. Zvakadai sekusarudzwa kwedhayamita 1-3μm basalt faibha yakagadzirwa (density ye15 kg/m3, ukobvu hwe30mm) zvinhu zvinobata ruzha, muodhiyo ye100-300 Hz, 400-900 Hz uye 1200-7,000 HZ mamiriro, iyo fiber material inotorwa ~010. 0.22 ~ 0.75 uye 0.85 ~ 0.93, zvichiteerana.
⑦ Yakakosha dielectric properties
Iro vhoriyamu resistivity yekuenderera mberi basalt fiber iodha imwe yehukuru yakakwira kupfuura iyoE glass fiber, iyo ine yakanakisa dielectric properties. Kunyangwe iyo basalt ore iine chikamu chikuru chinosvika 0.2 cheiyo conductive oxides, asi kushandiswa kweakakosha kupinza mumiririri akakosha epamusoro kurapwa, iyo basalt fiber dielectric yekushandisa angle tangent pane girazi fiber iri 50% yakaderera, vhoriyamu resistivity yefiber zvakare yakakwirira kupfuura iyo girazi fiber.

⑧ Natural silicate kuenderana
Kupararira kwakanaka nesamende nekongiri, kusungirirana kwakasimba, coefficient inowirirana yekuwedzera kwekupisa uye kuderera, kumira kwakanaka kwemamiriro ekunze.
⑨ Kutora mwando pasi
Kunwa kwehunyoro hwebasalt fiber iri pasi pe0.1%, yakaderera pane aramid fiber, rock wool uye asbestos.
⑩ Lower thermal conductivity
Thermal conductivity yebasalt fiber ndeye 0.031 W / mK - 0.038 W / mK, iyo yakaderera pane iyo aramid fiber, alumino-silicate fiber, alkali-isina girazi fiber, rockwool, silicon fiber, carbon fiber uye simbi isina tsvina.

Fiberglass
Fiberglass, inorganic isiri-metallic zvinhu zvine mashandiro akanaka, ine zvakawanda zvakasiyana-siyana zvakanaka senge kuvharidzira kwakanaka, kupisa kupisa, kunaka kwekusagadzikana, kusimba kwemagetsi, asi iyo yakashata ndeye brittle uye kushomeka kweabrasion kuramba. Inobva pa chlorite, jecha requartz, limestone, dolomite, boron calcium dombo, boron magnesium dombo nhanhatu mhando dzeores seyakagadzirwa nepamusoro-tembiricha kunyunguduka, kudhirowa, mhepo, kurukwa uye mamwe maitiro mukugadzira dhayamita yemonofilament yayo kwema microns mashoma kusvika kune anopfuura 20 microns, yakaenzana ne1/5, 1/20 bvudzi rebvudzi rimwe nerimwe. mazana kana kunyange zviuru zvemonofilament kuumbwa.Fiberglassinowanzoshandiswa sezvinhu zvekusimbisa muzvinhu zvinosanganiswa, magetsi ekudzivirira zvinhu uye zvigadziriswe zvinopisa, mabhodhi edunhu uye dzimwe nzvimbo dzehupfumi hwenyika.

Material Properties
Melting point: girazi imhando yeisina-crystalline, hapana yakanyungudika yakanyungudika, inotendwa kuti iyo inopfava ye500 ~ 750 ℃.
Nzvimbo yekubikira: inenge 1000 ℃
Kuwanda: 2.4 ~ 2.76 g/cm3
Kana girazi faibha richishandiswa sekusimbisa zvinhu zvemapurasitiki akasimbiswa, chinhu chikuru ndechekusimba kwayo kwepamusoro. Kusimba kwesimba munzvimbo yakajairika i6.3 ~ 6.9 g / d, mamiriro emvura 5.4 ~ 5.8 g / d. Kupisa kupisa kwakanaka, tembiricha inosvika 300 ℃ pane simba rekushaya simba. Iyo ine yakanakisa magetsi ekudzivirira, ndeye yakakwirira-yepamusoro yemagetsi ekudzivirira zvinhu, inoshandiswawo pakugadzira zvinhu uye zvinhu zvinodzivirira moto. Kazhinji inongosvibiswa chete neyakaomeswa alkali, hydrofluoric acid uye yakadzika phosphoric acid.
