Hluav taws xobfiberglass ntaubntaub npuag

Electronic qib iav fiber ntau daim ntaub siv nyob rau hauv cov iav muaj pes tsawg leeg yog aluminium carbon silicate, feem ntau hu uaalkali dawb iav, thoob ntiaj teb hu ua E iav, uas yog hluav taws xob insulating iav.

Cov iav tsis ua haujlwm yog hais txog txhuas code silicate iav nrog alkali hlau oxide cov ntsiab lus tsawg dua 1%. Lub khob no yog thawj zaug tsim los rau kev siv hluav taws xob, tab sis nws daim ntawv thov tam sim no tau dhau mus dhau qhov ntawd thiab tau dhau los ua ib tus qauv iav thoob ntiaj teb, suav nyiaj rau 80-90% ntawm tag nrho cov khoom lag luam thoob ntiaj teb.

Tam sim no, cov iav muaj pes tsawg leeg ntawm E iav fiber ntau tsim nyob rau hauv tag nrho cov teb chaws nyob rau hauv lub ntiaj teb no yog roughly tib yam, thiab nws cov ntsiab Cheebtsam yog tag nrho cov Yog li, A0, Cao ternary system. Qhov hnyav feem pua ​​tsuas yog hloov pauv hauv qhov me me. Qhov kev hloov pauv yog kwv yees li hauv qab no: Si02 53% -56%; A20, 14% mus rau 18%. Ca0 20% 24%; Na20 + K0 0.5% ~ 1.0%; B0, 5% rau 10

Cov hluav taws xob rwb thaiv tsev kev ua tau zoo ntawm cov ntaub ntawv hluav taws xob iav fiber ntau yog siab heev. Nyob rau hauv chav tsev kub, nws ntim resistivity thiab nto resistivity yog ntau tshaj 10″0.cm. Ntawm qhov zaus ntawm 10 ° H, lub dielectric poob lub kaum sab xis ntawm 4 yog 1.1 × 10-. Daim ntawv thov ib txwm dielectric e yog 6.6, thiab alkali dawb iav fiber ntau muaj lub zog siab, thiab nws lub zog tshiab ecological zog yog txog 3.5GPa. Lub elastic modulus yog 730CPa. Nws yog tsim nyog hais tias cov hlau oxide nyob rau hauv iav muaj pes tsawg leeg yog Na, 0

Cov ntsiab lus ntawm + K20 yog qhov tseem ceeb cuam tshuam rau kev ua haujlwm hluav taws xob rwb thaiv tsev ntawm iav fiber. Txhawm rau txhim kho cov hluav taws xob rwb thaiv tsev ntawm iav fiber ntau, cov ntsiab lus ntawm alkali hlau oxides hauv cov iav iav yuav tsum tau tswj nruj me ntsis.

Kev ntsuam xyuas tau ua pov thawj tias cov ntsiab lus ntawm Nap0 + K, 0 hauv iav fiber ntau txo los ntawm 1.6% mus rau 0.5%. Tom qab ntawd lub ntim tsis kam ntawm iav fiber ntau tuaj yeem nce los ntawm 10 qhov ntau
