Ifihan ti Quartz Fiber:
Agbara fifẹ 7GPa, modulus fifẹ 70GPa, mimọ SiO2 ti okun quartz jẹ diẹ sii ju 99.95%, pẹlu iwuwo ti 2.2g / cm3.
O jẹ ohun elo okun inorganic rọ pẹlu ibakan dielectric kekere ati resistance otutu giga. Quartz fiber yarn ni awọn anfani alailẹgbẹ ni aaye ti iwọn otutu giga-giga ati afẹfẹ afẹfẹ, o jẹ aropo ti o dara fun E-gilasi, silica giga, ati okun basalt, aropo apa kan fun aramid ati okun carbon. Ni afikun, olùsọdipúpọ imugboroja laini jẹ kekere, ati modulu rirọ n pọ si nigbati iwọn otutu n pọ si, eyiti o ṣọwọn lainidii.

Pṣiṣe:
1. Dielectric-ini: kekere dielectric ibakan
Okun Quartz jẹ awọn ohun-ini dielectric ti o dara julọ, paapaa awọn ohun-ini dielectric iduroṣinṣin ni awọn igbohunsafẹfẹ giga ati awọn iwọn otutu giga. Pipadanu dielectric ti okun quartz jẹ 1/8 nikan ti D-gilasi Ni 1MHz. Nigbati iwọn otutu ba kere ju 700 ℃, dielectric ibakan ati ipadanu dielectric ti okun quartz ko yipada pẹlu iwọn otutu.
2.Agbara otutu-giga giga, igbesi aye gigun ni iwọn otutu ti 1050 ℃-1200 ℃, rirọ otutu 1700 ℃, resistance mọnamọna gbona, igbesi aye iṣẹ to gun
3. Itọpa ina gbigbona kekere, kekere imugboroja igbona nikan 0.54X10-6/ K, eyiti o jẹ idamẹwa ti okun gilasi lasan, mejeeji sooro ooru ati idabobo ooru
4. Agbara giga, ko si micro-cracks lori dada, agbara fifẹ to 6000Mpa, eyiti o jẹ awọn akoko 5 ti okun silica giga, 76.47% ti o ga ju ti E-glass fiber
5. Iṣẹ idabobo itanna to dara, resistivity 1X1018Ω · cm ~ 1X106Ω · cm ni iwọn otutu 20 ℃ ~ 1000 ℃. Ohun elo idabobo itanna bojumu
6. Awọn ohun-ini kemikali iduroṣinṣin, ekikan, ipilẹ, iwọn otutu ti o ga, otutu, nina resistance resistance. Idaabobo ipata
