Epoxy yeeb nkab manufacturers piav qhia cov yam ntxwv ntawm ntau yam ntaub ntawv insulating Epoxy yeeb nkab manufacturers piav qhia txog cov yam ntxwv ntawm ntau yam ntaub ntawv insulating
Epoxy yeeb nkab manufacturers piav txog cov yam ntxwv ntawm ntau yam ntaub ntawv insulating:
muaj ntau hom ntaub ntawv insulating, uas tuaj yeem muab faib ua peb pawg: roj, kua thiab khoom. Feem ntau siv roj insulating cov ntaub ntawv suav nrog huab cua, nitrogen, thiab sulfur hexafluoride insulating PC films. Cov ntaub ntawv insulating kua feem ntau suav nrog cov roj ntxhia insulating roj thiab cov roj hluavtaws hluavtaws (silicone roj, dodecylbenzene, polyisobutylene, isopropyl biphenyl, diarylethane, thiab lwm yam). Cov khoom siv insulating tuaj yeem muab faib ua ob pawg: organic thiab inorganic. Organic khoom insulating cov ntaub ntawv muaj xws li insulating xim, insulating kua nplaum, insulating ntawv, insulating fiber ntau cov khoom, yas, roj hmab, varnished varnished kav thiab insulating impregnated fiber khoom, hluav taws xob films, composite khoom thiab nplaum tapes, hluav taws xob laminates, thiab lwm yam Inorganic khoom insulating cov ntaub ntawv mas suav nrog mica, iav, ceramics thiab lawv cov khoom. Nyob rau hauv sib piv, cov khoom insulating khoom muaj ntau haiv neeg thiab tseem ceeb tshaj plaws.
Cov khoom siv hluav taws xob sib txawv muaj qhov sib txawv rau kev ua haujlwm ntawm cov ntaub ntawv insulating. Cov ntaub ntawv rwb thaiv tsev rau cov khoom siv hluav taws xob siab xws li cov motors high-voltage thiab high-voltage cables yuav tsum muaj lub zog tawg siab thiab tsis muaj dielectric poob. Cov khoom siv hluav taws xob uas tsis tshua muaj hluav taws xob siv lub zog siv tshuab, elongation ntawm kev tawg, qib kub tsis kam, thiab lwm yam raws li qhov yuav tsum tau ua.
Cov khoom macroscopic ntawm insulating cov ntaub ntawv xws li hluav taws xob, thermal zog, mechanical zog, tshuaj tsis haum, huab cua tsis kam, corrosion kuj thiab lwm yam khoom muaj ze ze rau nws cov tshuaj muaj pes tsawg leeg thiab molecular qauv. Inorganic khoom insulating cov ntaub ntawv feem ntau yog tsim los ntawm silicon, boron thiab ntau yam hlau oxides, feem ntau ionic qauv, lub ntsiab feature yog kub kub tsis kam, ua hauj lwm kub yog feem ntau siab tshaj 180 ℃, zoo stability, tsis kam mus atmospheric laus, kuj zoo tshuaj thiab ntev kev laus kev ua tau zoo nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb; tab sis siab brittleness, tsis tshua muaj kev cuam tshuam lub zog, siab ua haujlwm siab thiab tsis tshua muaj zog tensile; kev ua haujlwm tsis zoo. Organic cov ntaub ntawv feem ntau yog cov polymers nrog qhov nruab nrab molecular hnyav ntawm 104 thiab 106, thiab lawv cov tshav kub tsis kam yog feem ntau qis dua cov ntaub ntawv inorganic. Lub tshav kub tsis kam ntawm cov ntaub ntawv uas muaj cov nplhaib uas muaj ntxhiab, heterocycles thiab cov khoom xws li silicon, titanium, thiab fluorine yog siab dua li cov ntaub ntawv linear polymer.
Cov yam tseem ceeb uas cuam tshuam rau dielectric zog ntawm cov ntaub ntawv insulating yog lub zog ntawm molecular polarity thiab cov ntsiab lus ntawm polar Cheebtsam. Lub dielectric tas li thiab dielectric poob ntawm cov ntaub ntawv polar yog siab dua li cov ntaub ntawv uas tsis yog-polar, thiab nws yooj yim rau adsorb impurity ions kom nce conductivity thiab txo nws cov dielectric zog. Yog li ntawd, kev saib xyuas yuav tsum tau them rau kev huv hauv kev tsim cov khoom siv insulating kom tsis txhob muaj kuab paug. Dielectrics rau capacitors yuav tsum muaj siab dielectric tas li los txhim kho lawv cov yam ntxwv tshwj xeeb.
