Dab tsi yog qhov ua haujlwm ntawm kev txiav lub tshuab hluav taws xob hluav taws xob cua sov raj?

Kauj ruam kawg hauv kev ua hluav taws xob cua kub tub rog tau sib khi. Ntau tus neeg muas zaub nug, dab tsi yog lub hom phiaj ntawm kev txiav hluav taws xob hluav taws xob cua sov? Niaj hnub no, peb mam piav qhia.

Nyob rau hauv cov qauv ntawm hluav taws xob cua sov raj, qhov chaw nruab nrab ntawm cov hlau uas tsis kam ntim nrog cov hmoov ua ke nrog cov hmoov ua ke nrog cov hmoov ua ke (feiyu ib txwm siv siab {{ Thaum qhuav thiab ntom, tus muab tub lim no muaj cov kev ua haujlwm zoo thiab rwb thaiv tsev.

Txawm li cas los xij, nws cov kev ua tau zoo drawbback yog nws hygroscopicity. Thaum cov tub lim cov khoom siv raug nthuav tawm ntawm ob xaus ntawm lub raj nqus dej noo, nws cov hluav taws xob rwb thaiv tsev ua haujlwm yuav raug txo qis. Qhov no yuav ua rau hluav taws xob conduction rau saum npoo ntawm lub raj hluav taws xob hluav taws xob cua sov, ua cov phom sij nyab xeeb.

Tsis tas li ntawd, thaum magnesium oxide hmoov nqus dej noo, qee qhov nws yuav hydrate (tshwj xeeb yog cov chaw tsis zoo lossis tsis tiav lossis tsis tiav crystallization).

Rau hluav taws xob cua kub taub hau, lub raj qhib kev nqus cov feem ntau noo noo thiab yog lub nquag ua kom tau. Thaum noj ntawm lub raj qhib, nws nyuaj dua rau cov dej noo nqus mus rau cov khoom siv ua kom deb ntawm cov raj qhib kev khiav dim. Qhov no tuaj yeem ua rau lub raj hluav taws xob hluav taws xob ua kom tsis txhob rov zoo li nws cov rwb thaiv tsev txawm tias muaj hluav taws kub thiab ua kom sov. Qhov tseeb, noo noo nyob rau hauv lub raj tuaj yeem txawm vaporize thiab nthuav dav vim kub, ua rau lub raj ntsa mus rau kev thawb lossis tawg.

Rwb thaiv tsev txo qis thaum ua kom yaa dej, thiab cov coarsening ntawm cov molecular hais tom qab kev rov ua hluav taws xob rov qab ua hluav taws xob tsis kam. Rau ob qho laj thawj no, qhov xaus ntawm lub raj hluav taws xob cua sov yuav tsum tau muab ntim.
