10 Qhov Zoo Tshaj Plaws ntawm Basalt Fiber

Basalt Fiber: 10 Qhov Zoo Tshaj Plaws

Cov fiber basaltyog ib qho fiber txuas ntxiv ua los ntawm cov khoom siv ntuj Pob zeb Basalt. Lub pob zeb yog yaj ntawm 1450 ° C-1500 ° C thiab tom qab ntawd rub los ntawm platinum-rhodium alloy bushing ntawm kev kub ceev. Cov fiber basalt ntshiab feem ntau yog xim av. Nws yog ib hom tshiab ntawm inorganic, eco-friendly, high-performance fiber uas muaj cov oxides xws li silicon dioxide, txhuas oxide, calcium oxide, magnesium oxide, hlau oxide, thiab titanium dioxide. Basalt txuas ntxiv fiber tsis tsuas yog muaj lub zog siab tab sis kuj muaj cov khoom zoo heev xws li hluav taws xob rwb thaiv tsev, corrosion tsis kam, thiab kub siab tiv taus. Ntxiv mus, nws cov txheej txheem tsim khoom tsim cov khib nyiab tsawg kawg nkaus thiab kev ua qias tuaj ib puag ncig, thiab cov khoom pov tseg tuaj yeem lwj tsis muaj kev puas tsuaj, ua rau nws yog cov khoom ntsuab thiab eco-friendly tiag tiag. Tuam Tshoj tau teev cov fiber basalt ua ib qho ntawm plaub lub fibers tseem ceeb rau kev txhim kho (nrog rau carbon fiber, aramid, thiab ultra-high molecular weight polyethylene) thiab tau ua tiav kev lag luam. Cov fiber basalt txuas ntxiv tam sim no siv dav hauv cov khoom sib xyaw ua ke fiber, cov ntaub ntawv sib txhuam, kev tsim nkoj, kev lag luam tsheb, thiab kev siv kub siab thiab kev tiv thaiv.

1. Cov Khoom Siv Raw Ntau

   Cov fiber basalt yog ua los ntawm pob zeb basalt, uas pom muaj ntau heev ntawm lub ntiaj teb thiab lub hli. Qhov no ua rau cov nqi khoom siv raw qis dua.

2. Khoom siv zoo rau ib puag ncig

   Basalt Pob zeb yog ib yam khoom siv ntuj tsim. Nws cov txheej txheem tsim khoom tsis tso tawm boron lossis lwm yam alkali hlau oxides, yog li cov hmoov av thiab pa luam yeeb tsis muaj cov tshuaj lom neeg thiab tsis ua rau huab cua qias neeg. Cov khoom kuj muaj lub neej ntev, ua rau nws pheej yig, ua haujlwm tau zoo, thiab huv si cov khoom siv ntsuab tshiab.

3. Kub thiab Dej Tsis kam

   Txuas ntxiv mus basalt fiber tuaj yeem ua haujlwm hauv qhov kub thiab txias ntau ntawm -269 ° C txog 700 ° C (nrog rau qhov taw tes mos ntawm 960 ° C). Qhov no zoo dua li gcov fiber ntau (-60°C txog 450°C) thiab carbon fiber (siab tshaj 500°C). Qhov tseem ceeb, basalt fiber khaws cia 80% ntawm nws lub zog qub tom qab ua haujlwm ntawm 600°C thiab tsis ntsws ntawm 860°C. Nws kuj tseem khaws cia lub zog siab tom qab raug dej kub 70°C.

4. Kev Ruaj Ntseg Tshuaj Zoo Thiab Kev Tiv Thaiv Kev Kub Ntxhov

   Cov fiber basalt muaj cov khoom xws li K₂O, MgO, thiab TiO₂, uas ua rau nws tsis kam rau tshuaj lom neeg thiab dej. Nws ruaj khov dua li cov iav fiber, tshwj xeeb tshaj yog nyob rau hauv alkaline thiab acidic ib puag ncig. Basalt fiber qhia tau tias nws tsis kam rau alkali corrosion hauv cov tshuaj Ca (OH)₂ saturated thiab cement.

5. Modulus Elastic Siab thiab Tensile Zog

   Basalt fiber lub elastic modulus (9100-11000 kg/mm) siab dua li E-iav fiber, asbestos, aramid, polypropylene, thiab silicon fibers. Nws lub zog tensile (3800-4800 MPa) siab dua li cov carbon fiber loj, aramid, PBI fiber, steel fiber, boron fiber, thiab alumina fiber, thiab zoo ib yam li S-iav fiber. Nrog qhov ceev ntawm 2.65-3.00 g/cm³ thiab Mohs hardness ntawm 5-9, nws muaj kev tiv thaiv zoo heev thiab kev txhawb nqa tensile. Nws lub zog kho tshuab ntau dua li cov ntuj thiab cov khoom siv hluavtaws, ua rau nws yog cov khoom siv txhawb nqa zoo tagnrho.

6. Kev Ua Haujlwm Zoo Tshaj Plaws ntawm Kev Rwb Thaiv Suab

   Cov fiber basalt tas mus li muaj cov yam ntxwv zoo heev ntawm kev nqus suab thiab suab nrov. Nws cov coefficient nqus suab nce ntxiv nrog rau zaus. Piv txwv li, cov khoom siv nqus suab ua los ntawm 1-3 μm txoj kab uas hla basalt fibers (nrog qhov ceev ntawm 15 kg / m³ thiab tuab ntawm 30 hli) muaj cov coefficient nqus suab ntawm 0.05-0.15 ntawm 100-300 Hz, 0.22-0.75 ntawm 400-900 Hz, thiab 0.85-0.93 ntawm 1200-7000 Hz.

7. Cov Khoom Dielectric Tseem Ceeb

   Cov fiber basalt txuas ntxiv musQhov ntim resistivity yog qhov kev txiav txim siab ntawm qhov loj dua li E-iav fiber, muab nws cov khoom dielectric zoo heev. Txawm hais tias pob zeb basalt muaj ze li ntawm 0.2% conductive oxides, kev kho tshwj xeeb saum npoo nrog cov neeg sawv cev sizing tuaj yeem txo qhov dielectric poob tangent los ntawm 50% piv rau iav fiber, thiab nws qhov ntim resistivity kuj siab dua.

8. Kev Sib Tw Sib Xws ntawm Silicate Ntuj

   Nws tawg tau zoo thiab sib txuas nrog cov cement thiab cov pob zeb ua ke. Nws cov coefficients thermal expansion thiab contraction yog sib xws, thiab nws tiv taus huab cua zoo.

9. Kev Nqus Dej Tsawg

   Basalt fiber muaj qhov nqus dej noo tsawg dua 0.1%, uas qis dua li aramid fiber, pob zeb wool, thiab asbestos.

10. Kev Ua Haujlwm Thermal Tsawg

    Basalt fiber lub thermal conductivity yog 0.031-0.038 W / m · K, uas qis dua li aramid fiber, txhuas silicate fiber, E-iav fiber, pob zeb wool, silicon fiber, carbon fiber, thiab stainless hlau.
