Dab tsi yog cov khoom ntim hauv ib lub cua sov hluav taws xob hu ua?

Nag hmo, tus poj niam nug kuv tias: "Yuav Cua Sov Hais Siv Hauv Dej Cua Sov Toog Hluav Taws Xob Hluav Taws Xob?" Kuv ntseeg cov neeg muaj coob tus muaj cov lus nug no. Yog li, cia kuv piav qhia.

Ua ntej, hluav taws xob cua sov cov khoom siv hluav taws xob yog cov khoom. Thib ob, saum npoo ntawm cov cua sov hauv tsev tsis muaj hluav taws xob. Vim li cas qhov no? Cia kuv piav qhia kom meej hauv qab no.

[Duab ntawm hluav taws xob cua kub caij nyoog] lub rwb thaiv tsev saum npoo av thiab tsis - xob hluav taws xob hluav taws xob ntawm lub tshuab hluav taws xob hluav taws xob feem ntau yog vim yog cov khoom siv rau sab hauv. Txoj haujlwm ntawm cov muab tub lim khoom yog:

1. Los muab hluav taws xob rwb thaiv tsev ntawm cov hlau kub thiab raj hlau;

2. Txhawm rau ua cov cua sov tsim los ntawm cov hlau cua kub rau saum npoo ntawm lub raj;

3. Txhawm rau kho qhov chaw ntawm cov cua kub hlau hauv lub raj.

Vim tias cov tub lim cov khoom ua tiav ua tiav cov haujlwm no, peb paub tias cov nplaim hluav taws xob cua sov tsis muaj hluav taws xob. Vim li cas thiaj nyob hauv cov khoom siv no.

Cov ntsiab lus saum toj no piav qhia lub luag haujlwm ntawm tus muab tub lim. Qhov tseeb, tus muab tub lim kuj yuav tsum tau ua kom tau raws li cov cai hauv qab no, feem ntau yog:

Txaus insulation thiab dielectric zog;

Tus coefficient ntawm thermal expansion zoo ib yam li cov cua kub;

Zoo thermal conductivity, piv txwv li, lub siab thermal caperivity coefficient;

Tshuaj lom neeg inertness rau cov khoom cua kub hlau;

Tsawg hygroscopicity (qis hygroscopicity txo rwb thaiv tsev tsis kam);

Kev tiv thaiv kub;

Muaj peev xwm tiv thaiv kom sov hloov pauv;

Cov khoom siv kho txhua yam;

Muaj kev txaus siab thiab tus nqi tsawg.

Ntsib tag nrho cov kev xav tau ib qho kev xav tsis yooj yim, vim tias feem ntau, cov thermal zoo condal kuj tseem yog hluav taws xob coj ua; Kev hluav taws xob rwb thaiv hluav taws xob cov khoom ua rau muaj cov thermal tsawg dua. Yog li ntawd, hauv kev sib piv, feem ntau siv fillers rau hluav taws xob cua sov siv hluav taws xob feem ntau yog peb pawg xuab zeb, hlau nplaum txhuas, thiab magnesium alide, thiab magnesium txhuas. Quartz xuab zeb tsis yog siv thaum lub caij kub ntawm cov cua sov tshaj 400-450℃vim tias nws rwb thaiv tsev tsis kam pib 450 degree. Yog li ntawd, Quartz xuab zeb yog qhov tsis haum raws li ib tug muab tub lim thaum lub qhov cub tawg ntawm cov cua sov tshaj 450 degree.

Magnesium oxide hmoov cov khoom ua pov thawj tsis tu ncua kev hloov kho cov khoom hluav taws xob zoo li qhov kub nce ntxiv. Peb yuav tsum xaiv ntau hom kev sib txawv ntawm cov tshuaj magnesium oxide raws li cov kev ua haujlwm sib txawv.

Cov khoom sib txawv cov ntaub ntawv siv hauv cov hluav taws xob cua sov ncaj qha cuam tshuam lawv tus nqi thiab lub neej. Raws li cov lus hais mus, "Koj tau txais yam koj them!" Qhov ntawd yog txhua yam rau hnub no txog cov npe ntawm cov muab faus rau hauv hluav taws xob cua sov.
