Silica Refractory Cib

1.Resistance rau Acid-Base

silica cib yog cov khoom siv acid refractory uas tiv taus yaig los ntawm cov kua qaub slag thiab CaO, FeO, thiab Fe2O3 oxides. Txawm li cas los xij, silica hluav taws cib tau yooj yim raug mob los ntawm Al2O3 oxide thaum alkali slag tau ua rau nws hnyav heev.

2.Expansibility

Lub thermal conductivity thiab huab hwm coj ntawm silica refractory cib nce ntxiv thaum qhov kev pabcuam kub nce. Thaum lub sij hawm ci, tsis muaj linear tom qab contraction. Tus nqi nthuav dav thaum ci yog kwv yees li 70-75 feem pua ​​​​ntawm tag nrho cov nyiaj nthuav dav ua ntej 300 degree, nrog qhov loj tshaj plaws nthuav tawm ntawm 100 thiab 300 degree. Thaum lub sij hawm ci, SiO2 tau ntsib plaub crystalline daim ntawv inversion cov ntsiab lus ntawm 117, 163, 180270, thiab 573 degree. uas cristobalite feem ntau cuam tshuam ntawm 180 thiab 270 degree.

3.Thermal tsis kam ua haujlwm

Lub silica cib muaj kev ruaj ntseg zoo nyob rau hauv qhov kub siab.Qhov spectrum ntawm daim ntawv thov rau silica refractory cib yog txwv los ntawm nws cov thermal shock tsis kam thiab refractoriness, uas yog nyob ib ncig ntawm 1690-1730 degree. Qhov tseem ceeb tshaj plaws uas cuam tshuam rau lub tshav kub conductivity ntawm silica hluav taws cib yog qhov tseeb ceev. Yuav muaj tsawg dua tom qab nthuav dav thaum ci vim tias qhov qis dua qhov tseeb thiab ntau dua cov txiv qaub hloov dua siab tshiab.

Yuav ua li cas Silica bricks yog tsim?

Tridymite, cristobalite, silica, thiab iav theem yog siv los tsim silica cib, nrog ntuj silica ua cov khoom siv raw. Mineralizer yog ntxiv rau qhov kom muaj nuj nqis, thiab qhov sib tov yog tom qab ntawd nchuav rau hauv tus neeg sawv cev khi.

Kev tsim khoom ntawm Silica Bricks
Silica pob zeb muaj SiO2 cov ntsiab lus ntau dua 96 feem pua ​​​​yog siv los ua silica cib nrog rau molasses, lignosulfite, thiab mineralizers xws li hlau los yog txiv qaub mis nyuj. Cov kauj ruam ntawm kev sib xyaw, molding, ziab, thiab hlawv yog siv los tsim cov silica cib. Cov kab mob txaus ntshai tshaj plaws hauv kev tsim cov silica cib suav nrog Al2O3, K2O, Na2O, thiab lwm yam uas ua rau txo qis qis ntawm refractoriness ntawm cov khoom refractory.

Topower Refractory yog lub chaw tsim khoom muaj koob npe ntawm silica cib uas tuaj yeem muab cov nqi pheej yig, zoo silica cib. Txais tos tiv tauj peb rau kev kwv yees dawb yog tias koj txaus siab rau peb cov silica bricks lossis lwm yam refractory hluav taws cib!
