Lub cev muaj zog rwb thaiv tsev thiab kev tswj cov cai
Qhov kev ntseeg tau thiab kev pab cuam ntawm kev ua hauj lwm ntawm kev ua hauj lwm nyob ntawm seb qhov loj ntawm cov khoom siv insulating. Cov txheej txheem yooj yim rau kev ua tau zoo ntawm cov khoom siv insulating muaj hluav taws xob kev ua haujlwm, kev kub thiab kev ua haujlwm. Cov khoom hluav taws xob ntawm Ms. reference insulating cov ntaub ntawv yog luv luv hauv lub tweet dhau los. Niaj hnub no peb piav lub tshav kub tuaj thiab kev kho khoom thiab yog yooj yim. Qha cov kev cai numbering.
Kub tshav kub ntawm cov ntaub ntawv insulating
Txij li thaum lub cev muaj zog ua rau lub cev tsis sov vim lub sijhawm poob haujlwm, cov khoom siv insulating siv yuav tsum muaj cov cua kub zoo. Lub tshav kub tsis txaus ntawm cov khoom siv insulating ncaj qha txiav txim qhov tso cai kub nce ntawm lub tshuab. Raws li cov hluav taws xob-resistant insulating khoom, nws muab faib ua xya qib. Txhua qib tshav kub-resisting qib sib raug mus ua qee yam txwv kev siv kub. Hauv qab no kub, cov khoom siv hluav taws xob yuav siv tau ntev ntev yam tsis cuam tshuam nws cov kev ua tau zoo. Tsis tas li ntawd, cov khoom siv insulating yuav tsum muaj cov thermal conductivity thiab lub peev xwm loj kub. Loj lub cev muaj zog loj kuj yuav tsum tau ua kom txoj hlua khov ntawm cov khoom siv thev naus laus zis nyob ze ntawm cov khoom siv hluav taws xob kom tsis txhob muaj kev puas tsuaj thaum lub sij hawm thermal expansion thiab contraction.
Mechanical cov khoom ntawm insulating cov ntaub ntawv
Thaum cov kauj thiab cov cua ntsawj yog nyob rau hauv txheej txheem ntawm kev hnav khaub ncaws, sib sau thiab ntaus, thiab thaum lub cav khiav, lub rwb thaiv tsev yuav raug rau ntau yam kev txhawj xeeb, yog li muab cov khoom tsim nyog rau cov khoom siv insulating, xws li tensile, compressive thiab bending tsis kam. , kev sib zog ua haujlwm, lub zog, thiab lwm yam zoo li ntawd. Yog tias cov khoom siv cuab yeej insulating tsis zoo, nws yooj yim ua rau kev poob qis hauv kev hluav taws xob vim kev ua haujlwm. Muaj lwm txoj cai rau kev siv tshuaj insulating, xws li tsawg hygroscopicity; tsis kam mus rau acid, alkali, thiab roj; zoo acidity lossis lwm yam tshuaj uas yooj yim ionized; thiab yooj yim ntawm kev ua.
Yog tias koj xav yuav lub cav kiv cua, thov hu rau AC Fan Motor.
