Okwu mmalite nke Quartz Fiber:
Ike tensile 7GPa, modul tensile 70GPa, ịdị ọcha nke SiO2 nke eriri quartz karịrị 99.95%, yana njupụta nke 2.2g / cm3.
Ọ na-agbanwe ihe inorganic eriri ihe nwere ala dielectric mgbe niile na elu okpomọkụ na-eguzogide. Quartz fiber yarn nwere uru pụrụ iche n'ọhịa nke ultra-high okpomọkụ na ikuku ikuku, ọ bụ ezigbo nnọchi maka E-glass, akwa silica, na eriri basalt, nke na-anọchi anya aramid na carbon fiber. Na mgbakwunye, ọnụọgụ mgbasawanye linear ya dị ntakịrị, na modulus na-agbanwe agbanwe na-abawanye mgbe okpomọkụ na-abawanye, nke dị oke ụkọ.

Parụmọrụ:
1. Ngwongwo dielectric: obere dielectric mgbe niile
Fiber Quartz bụ ezigbo dielectric Njirimara, ọkachasị akụrụngwa dielectric kwụsiri ike n'ogo dị elu na oke okpomọkụ. Ọnwụ dielectric nke eriri quartz bụ naanị 1/8 nke D-glass Na 1MHz. Mgbe okpomọkụ dị ala karịa 700 ℃, dielectric mgbe niile na dielectric ọnwụ nke quartz eriri adịghị agbanwe na okpomọkụ.
2.Ultra-elu okpomọkụ eguzogide, ogologo ndụ na okpomọkụ nke 1050 ℃-1200 ℃, nro okpomọkụ 1700 ℃, thermal ujo eguzogide, ogologo ọrụ ndụ
3. Obere conductivity thermal, obere ọnụọgụ mgbasawanye ọkụ naanị 0.54X10-6/K, nke bụ otu ụzọ n'ụzọ iri nke eriri iko nkịtị, ma okpomọkụ na-eguzogide ma na-ekpo ọkụ
4. Ike dị elu, ọ dịghị micro-cracks n'elu, ike mgbawa ahụ ruru 6000Mpa, nke bụ 5 ugboro nke eriri silica dị elu, 76.47% dị elu karịa nke E-glass fiber.
5. Ezigbo mkpuchi mkpuchi eletriki, resistivity 1X1018Ω · cm ~ 1X106Ω · cm na okpomọkụ 20 ℃ ~ 1000 ℃. Ihe mkpuchi ọkụ eletrik dị mma
6. Ngwongwo kemịkalụ kwụsiri ike, acidic, alkaline, okpomọkụ dị elu, oyi, nkwụsi ike na-adịgide adịgide. Nguzogide corrosion
