Matrix muaj pes tsawg leeg. Lub matrix muaj pes tsawg leeg muaj qhov cuam tshuam tseem ceeb ntawm daim ntawv thov kub, kub-kub txhua yam muaj nuj nqi, thiab sintering muaj nuj nqi ntawm refractory castables. Lub matrix yuav tsum muaj xws li qis K2O thiab Na2O cov ntsiab lus bauxite clinker, tswj tus nqi ntawm cov cement, optimize cov khoom xyaw, thiab ua rau cov matrix ntawm refractory castables kwv yees cov tshuaj muaj pes tsawg leeg ntawm mullite (A3S2). Ntawd yog, kho cov ntsiab lus ntawm Al2O3 thiab SiO2 hauv matrix los tsim mullite ntawm qhov kub thiab txias thiab ua rau me ntsis ntim nthuav dav, txhawm rau txhim kho thermal poob siab thiab lub zog kub.
Siab zog thiab siab aluminium castable
Fusion tus neeg sawv cev. Ntshiab calcium aluminate cement yog siv los ua tus neeg sawv cev fusion, thiab nws cov khoom tseem ceeb yog CaO. Al2O3 calcium aluminate muaj qhov decomposition kub ntawm 1600 degree, kev ua haujlwm siab, ib txwm agglutination tus nqi, ceev hardening tus nqi, siab pib lub zog, thiab tsis meej nce nyob rau hauv lub zog tom qab; Tus nqi ntawm hydration thiab hardening kuj qeeb, nrog qis pib lub zog thiab tom qab lub zog.
Tom qab hydration thiab agglomeration ntawm cov cement, nws yog ib qho tsim nyog yuav tsum tau sib koom ua ke ntawm cov khoom sib xyaw thiab hmoov ua ke nrog kev koom tes ntawm tsawg dua 5% Kev koom tes hauv qhov tsim nyog ntawm micro hmoov
Dispersant. Koom nrog qhov tsim nyog tus nqi ntawm dispersant (dej txo tus neeg sawv cev tuaj yeem ua rau kom muaj kev tawg ntawm micro hmoov hauv cov khoom siv casting, nce qhov kev ncua deb ntawm cov khoom, thiab txo lub ntiajteb txawj nqus thiab kev sib txhuam quab yuam)
