Silica Cib rau Coke Cub
Silica Cib rau Coke Cub
Siv: siv dav hauv coke qhov cub tsim hluav taws xob, chutes thiab chav sib txuas
Silica cib feem ntau yog cov khoom siv ua kua qaub ua los ntawm tridymite, cristobalite thiab me me ntawm cov seem quartz thiab iav theem.
nta:
Cov ntsiab lus silica siab dua 94%. Qhov tseeb ntom yog 2.35g/cm3. Nws muaj kev tiv thaiv rau acid slag yaig. Lub zog kub siab dua, pib qhov kub ntawm qhov muag muag yog 1620 ~ 1670 ℃. Nws yuav tsis deform tom qab siv sijhawm ntev ntawm qhov kub siab. Tsawg thermal poob siab ruaj khov (1 ~ 4 zaug ntawm kev sib pauv cua sov hauv dej) Ntuj silica tau siv los ua raw khoom, thiab tsim nyog kom muaj cov ntxhia ntxiv los txhawb kev hloov pauv quartz hauv lub cev ntsuab mus rau hauv phosphorite. Maj mam raug rho tawm ntawm 1350 ~ 14 30 ℃ hauv qab txo qhov cua. Thaum rhaub kom 1450 ℃, yuav muaj li 1.5 ~ 2.2% ntawm tag nrho cov ntim nthuav dav. Qhov kev nthuav dav ntxiv no yuav ua rau txiav cov pob qij txha kom nruj thiab ua kom ntseeg tau tias cov masonry muaj huab cua nruj thiab cov yam ntxwv muaj zog. Nyob rau tib lub sijhawm, nws muaj qhov zoo ntawm kev ua haujlwm ntev thiab txo kev siv zog.
