Pamusoro 10 Zvakanakira zveBasalt Fiber

Basalt Fiber: Pamusoro 10 Zvakanakira

Basalt fiberinoramba iine filament fiber yakagadzirwa kubva kune zvakasikwa Basalt Rock. Dombo rinonyungudutswa pa 1450 ° C-1500 ° C uye robva radhonzwa kuburikidza neplatinum-rhodium alloy bushing nekumhanya kukuru. Pure basalt fiber inowanzoita brown. Imhando itsva ye inorganic, eco-friendly, high-performance fiber inoumbwa nema oxides akaita sesilicon dioxide, aluminium oxide, calcium oxide, magnesium oxide, iron oxide, uye titanium dioxide. Basalt inoenderera mberi fiber haingove nesimba rakakwirira chete asi zvakare inozvirumbidza yakanakisa senge magetsi ekudzivirira, corrosion resistance, uye yakakwirira-tembiricha kuramba. Pamusoro pezvo, maitiro ayo ekugadzira anoburitsa tsvina shoma uye kusvibiswa kwezvakatipoteredza, uye chigadzirwa chakaraswa chinogona kudzikisira zvakasikwa pasina kukuvadzwa, zvichiita kuti chive chakasvibira zvechokwadi uye eco-hushamwari zvinhu. China yakanyora basalt faibha seimwe yeaya mana akakosha mafiber ebudiriro (pamwe nekabhoni faibha, aramid, uye Ultra-yakakwirira molecular uremu polyethylene) uye yakawana kugadzirwa kwemaindasitiri. Inoenderera mberi basalt fiber ikozvino inoshandiswa zvakanyanya mu fiber-reinforced composites, friction materials, shipbuilding, indasitiri yemotokari, uye yakakwirira-yekushisa uye yekudzivirira kushandiswa.

1. Yakawanda Raw Materials

   Basalt fiber inogadzirwa kubva kudombo rebasalt, rinowanikwa muhuwandu hwakakosha paPasi nepamwedzi. Izvi zvinoita kuti mari yemafuta irambe iri shoma.

2. Eco-Hushamwari Material

   Basalt dombo chinhu chechisikigo. Kugadzirwa kwayo hakuburitse boron kana mamwe alkali metal oxides, saka huruva nehutsi hazvina zvinhu zvinokuvadza uye hazvisvibise mhepo. Chigadzirwa chacho chinewo hupenyu hurefu, zvichiita kuti ive yakaderera-mutengo, yepamusoro-soro, uye yakachena zvinhu zvitsva zvakasvibirira.

3. High-Tembiricha uye Mvura Kuramba

   Continuous basalt fiber inogona kushanda mutembiricha yakakura ye -269°C kusvika 700°C (ine kupfava kwe960°C). Izvi zvinopfuura gtsvina fiber (-60 ° C kusvika 450 ° C) uye carbon fiber (max 500 ° C). Zvinoshamisa, basalt fiber inochengeta 80% yesimba rayo rekutanga mushure mekushanda pa600 ° C uye haidzike pa860 ° C. Inochengetedzawo simba repamusoro mushure mekuratidzwa kune 70 ° C mvura inopisa.

4. Yakanakisa Chemical Kugadzikana uye Corrosion Resistance

   Basalt fiber ine zvinhu zvakaita seK₂O, MgO, uye TiO₂, iyo inovandudza zvakanyanya kuramba kwayo kumarara kwemakemikari nemvura. Yakanyanya kugadzikana mumakemikari kupfuura girazi fiber, kunyanya munzvimbo dzine alkaline uye acidic. Basalt faibha inoratidza kunyangwe kurinani kuramba kune alkali corrosion mune yakazara Ca (OH) ₂ mhinduro uye simende.

5. Yakakwira Elastic Modulus uye Tensile Simba

   Basalt fiber's elastic modulus (9100-11000 kg/mm) yakakwirira kudarika yeE-glass fiber, asbestos, aramid, polypropylene, uye silicon fibers. Simba rayo rekusimba (3800-4800 MPa) rakakura kudarika guru-tow carbon fiber, aramid, PBI fiber, simbi fiber, boron fiber, uye alumina fiber, uye inofananidzwa neS-glass fiber. Iine density ye2.65-3.00 g/cm³ uye kuomarara kweMohs ye5-9, inopa yakanakisa kupfeka kuramba uye kusimba kwekusimbisa. Simba rayo remuchina rinopfuura nekure echisikigo uye ekugadzira fiber, zvichiita kuti ive yakanaka yekusimbisa zvinhu.

6. Yakanakisa Inzwi Insulation Performance

   Inoenderera mberi basalt fiber ine yakanakisa ruzha uye ruzha kunyudza zvivakwa. Inzwi rayo rekutora coefficient rinowedzera zvakanyanya ne frequency. Semuenzaniso, chinhu chinobata ruzha chakagadzirwa ne 1-3 μm dhayamita yebasalt fibers (ine density ye15 kg/m³ uye ukobvu hwe30 mm) ine mapikisi ekunyudza anonzwika e 0.05-0.15 pa 100-300 Hz, 0.22-0.75 pa 0.22-0.75 pa 500 040 Hz 50-90. 1200-7000 Hz.

7. Yakakurumbira Dielectric Properties

   Kuenderera mberi basalt fiber's vhoriyamu resistivity chirongwa chehukuru chakakwira kupfuura E-girazi fiber, ichichipa yakanakisa dielectric zvivakwa. Kunyangwe dombo rebasalt riine ingangoita 0.2% conductive oxides, kurapwa kwakakosha kwepamusoro neanoshandisa saizi kunogona kuderedza dielectric kurasikirwa tangent ne50% zvichienzaniswa negirazi fiber, uye vhoriyamu yayo resistivity yakakwira zvakare.

8. Natural Silicate Compatibility

   Inopararira zvakanaka uye inosungirirana zvakasimba nesamende uye kongiri. Kuwedzera kwayo kupisa uye kukanda coefficients inopindirana, uye ine yakanaka yekudzivisa mamiriro ekunze.

9. Low Moisture Absorption

   Basalt faibha ine mwero wekunyudza hunyoro pasi pe0.1%, iyo yakaderera pane aramid fiber, rock wool, uye asbestos.

10. Low Thermal Conductivity

    Basalt fiber's thermal conductivity i 0.031-0.038 W/m·K, iyo yakaderera pane aramid fiber, aluminium silicate fiber, E-glass fiber, rock wool, silicon fiber, carbon fiber, uye simbi isina tsvina.
