Ukuqaliswa kwe-Quartz Fiber:

Amandla e-tensile 7GPa, i-tensile modulus 70GPa, ukucoceka kwe-SiO2 ye-quartz fiber ingaphezulu kwe-99.95%, kunye nobuninzi be-2.2g / cm3.

Iyinto eguquguqukayo yefiber ye-inorganic fiber kunye ne-dielectric ephantsi rhoqo kunye nokumelana nobushushu obuphezulu. Umsonto we-quartz uneenzuzo ezizodwa kwintsimi yobushushu obuphezulu kunye ne-aerospace, iyindawo efanelekileyo ye-E-glass, i-silica ephezulu, kunye nefayibha ye-basalt, ithatha indawo ye-aramid kunye ne-carbon fiber. Ukongeza, i-coefficient yayo yokwandisa i-linear incinci, kwaye i-elastic modulus iyanda xa ubushushu bonyuka, into enqabileyo kakhulu.

1. Iimpawu ze-Dielectric: i-dielectric ephantsi rhoqo

I-quartz fiber ineempawu ezibalaseleyo ze-dielectric, ngakumbi iipropathi ezizinzileyo ze-dielectric kumaza aphezulu kunye namaqondo obushushu aphezulu. Ilahleko ye-dielectric ye-quartz fiber yi-1/8 kuphela ye-D-glass Kwi-1MHz. Xa ubushushu bungaphantsi kwe-700 ℃, i-dielectric engaguqukiyo kunye nelahleko ye-dielectric ye-quartz fiber ayitshintshi kunye nobushushu.

2.Ukumelana nobushushu obuphezulu, ixesha elide kubushushu be-1050 ℃-1200 ℃, ukuthambisa ubushushu be-1700 ℃, ukuxhathisa ukothuka kwe-thermal, ubomi obude benkonzo

3. I-conductivity ephantsi ye-thermal, i-coefficient yokwandisa i-thermal encinci kuphela i-0.54X10-6/ K, esisishumi se-fiber yeglasi eqhelekileyo, zombini ukumelana nobushushu kunye nobushushu obufakwe ngaphakathi

4. Amandla aphezulu, akukho micro-cracks phezu komhlaba, amandla e-tensile afikelela kwi-6000Mpa, ephindwe ka-5 ye-silica fiber ephezulu, i-76.47% ephezulu kune-E-glass fiber.

5. Ukusebenza kakuhle kokufakelwa kombane, ukuxhathisa 1X1018Ω · cm~1X106Ω · cm kwiqondo lokushisa 20 ℃ ~ 1000 ℃. Isixhobo esifanelekileyo sokufakelwa kombane

6. Iimpawu zeekhemikhali ezizinzileyo, i-acidic, i-alkaline, ubushushu obuphezulu, ukubanda, ukuchasana nokuqina. Ukumelana nokubola
