Kenyelletso ea Quartz Fiber:
Matla a 7GPa, tensile modulus 70GPa, bohloeki ba SiO2 ba fiber ea quartz bo feta 99.95%, ka boima ba 2.2g / cm3.
Ke thepa ea fiber e feto-fetohang e nang le dielectric e tlase e sa fetoheng le mocheso o phahameng oa ho hanyetsa. Khoele ea fiber ea quartz e na le melemo e ikhethang tšimong ea mocheso o phahameng haholo le sebaka sa sefofane, ke sebaka se setle sa E-glass, silica e phahameng, le fiber ea basalt, e nkelang sebaka sa aramid le carbon fiber. Ho feta moo, coefficient ea eona ea ho atolosa e nyenyane, 'me modulus ea elastic e eketseha ha mocheso o ntse o eketseha, e leng ntho e sa tloaelehang haholo.

Ptshebetso:
1. Lintho tsa dielectric: kamehla dielectric e tlaase
Quartz fiber e na le thepa e ntle haholo ea dielectric, haholo-holo thepa ea dielectric e tsitsitseng ka maqhubu a phahameng le mocheso o phahameng. Tahlehelo ea dielectric ea fiber ea quartz ke 1/8 feela ea khalase ea D Ho 1MHz. Ha mocheso o le ka tlase ho 700 ℃, tahlehelo ea dielectric le dielectric fiber ea quartz ha e fetohe ka mocheso.
2.Ho hanyetsa mocheso o phahameng haholo, nako e telele ea bophelo ka mocheso oa 1050 ℃-1200 ℃, mocheso o nolofatsang 1700 ℃, ho hanyetsa mocheso oa mocheso, bophelo bo bolelele ba tšebeletso.
3. Conductivity e tlaase ea mocheso, coefficient e nyenyane ea ho atolosa mocheso 0.54X10 feela-6/K, e leng karolo ea leshome ea fiber e tloaelehileng ea khalase, e sa keneleng mocheso le e sa keneng mocheso
4. Matla a phahameng, ha ho na mapetso a manyenyane holim'a metsi, matla a ho tsitsa a fihla ho 6000Mpa, e leng makhetlo a 5 a fiber e phahameng ea silica, 76.47% e phahameng ho feta ea E-glass fiber.
5. Ts'ebetso e ntle ea ho pata motlakase, ho hanyetsa 1X1018Ω · cm ~ 1X106Ω · cm ka mocheso oa 20 ℃ ~ 1000 ℃. Sesebelisoa se loketseng sa insulating ea motlakase
6. Lintho tse tsitsitseng tsa lik'hemik'hale, acidic, alkaline, mocheso o phahameng, serame, ho otlolla ho hanyetsa ho tšoarella. Khanyetso ea kutu
