Hluav taws xob ceramics:
Cov kab hluav taws xob yog ib hom inorganic insulating khoom. Nws cov txiaj ntsig zoo li tus ncej insulator feem ntau yog nyob rau hauv nws txoj kev laus zoo, muaj zog ib puag ncig siv tau, muaj zog acid thiab alkali corrosion kuj, thiab hluav taws xob thiab txhua yam muaj zog. Nyob rau hauv 100 xyoo dhau los, nws yog ib qho ntawm cov khoom siv tseem ceeb rau cov ncej insulators. Txawm li cas los xij, vim tias tus nqi siab ntawm kev tsim khoom thiab kev thauj mus los, nrog rau cov pa phem thaum lub sijhawm tsim khoom, nws tsis tshua muaj siv los ua cov khoom siv rau cov ncej insulators tom qab qhov tshwm sim ntawm cov ntaub ntawv tshiab hauv xyoo tas los no.
Toughened iav:
Tempered iav kuj yog ib hom inorganic insulating khoom. Nws qhov kev ua tau zoo zoo ib yam li cov hluav taws xob ceramics, zoo heev hauv kev laus tiv thaiv thiab corrosion kuj, thiab kev ua haujlwm siab. Tam sim no, hluav taws xob ceramics tau raug hloov los ua ib qho ntawm cov khoom siv tseem ceeb rau cov ncej insulators hauv ntau qhov chaw.
Synthetic silicone roj hmab:
Qhov pom tseeb zoo ntawm hluavtaws silicone roj hmab yog lub zog siab thiab lub teeb yuag. Tom qab ib qho kev hloov kho, qhov kev tiv thaiv corrosion yuav zoo heev, thiab cov nqi ua haujlwm siab heev. Txawm li cas los xij, piv nrog rau thawj ob cov ntaub ntawv, kev txhim kho ntawm kev pib qeeb, qhov kev thov tsis tau nthuav dav.
