Taw qhia ntawm Quartz Fiber:

Tensile zog 7GPa, tensile modulus 70GPa, SiO2 purity ntawm quartz fiber ntau yog 99.95%, nrog ceev ntawm 2.2g / cm3.

Nws yog cov khoom siv tau yooj yim inorganic fiber ntau nrog tsis tshua muaj dielectric tsis tu ncua thiab qhov kub tsis kam. Quartz fiber ntau yarn muaj qhov tshwj xeeb zoo hauv thaj tsam ntawm qhov kub thiab txias thiab aerospace, nws yog ib qho zoo hloov rau E-iav, siab silica, thiab basalt fiber, ib nrab hloov rau aramid thiab carbon fiber. Tsis tas li ntawd, nws cov linear expansion coefficient yog me me, thiab elastic modulus nce thaum kub nce, uas yog heev tsawg.

Kev soj ntsuam ntawm cov tshuaj muaj pes tsawg leeg ntawm quartz fiber

Pkev ua haujlwm:

1. Dielectric zog: tsawg dielectric tas li

Quartz fiber ntau yog zoo heev dielectric zog, tshwj xeeb tshaj yog ruaj khov dielectric zog ntawm high zaus thiab kub. Lub dielectric poob ntawm quartz fiber tsuas yog 1/8 ntawm D-iav Ntawm 1MHz. Thaum kub qis dua 700 ℃, qhov dielectric tas li thiab dielectric poob ntawm quartz fiber tsis hloov nrog kub.

2.Ultra-siab kub tsis kam, lub neej ntev ntawm qhov kub ntawm 1050 ℃ - 1200 ℃, softening kub 1700 ℃, thermal shock resistance, ntev kev pab cuam lub neej

3. Tsawg thermal conductivity, me me thermal expansion coefficient tsuas yog 0.54X10^-6/ K, uas yog ib feem kaum ntawm cov iav fiber ntau zoo tib yam, ob qho tib si kub-resistant thiab kub-insulated

4. Lub zog siab, tsis muaj micro-cracks ntawm qhov chaw, lub zog tensile yog txog 6000Mpa, uas yog 5 npaug ntawm cov silica fiber ntau, 76.47% siab dua li ntawm E-iav fiber ntau

5. Zoo hluav taws xob rwb thaiv tsev kev ua tau zoo, resistivity 1X1018Ω·cm ~ 1X106Ω·cm ntawm kub 20 ℃ ~ 1000 ℃. Ib qho zoo tagnrho hluav taws xob insulating khoom

6. Cov khoom siv ruaj khov, acidic, alkaline, kub, txias, stretching durability kuj. Corrosion kuj
