Refractory Cement Mortar

Refractory mortar tuaj yeem muab faib ua peb pawg hauv qab no raws li cov ntaub ntawv sib txawv:
(1) Ceramic bonded refractory mortar, uas yog ib qho sib xyaw ua ke ntawm refractory nplua aggregate thiab ceramic binder (yas av nplaum). Nws yog xa mus rau hauv lub xeev qhuav thiab yuav tsum tau ntxiv nrog dej ua ntej siv. Nws yog hardened los ntawm ceramic bonding ntawm high kub.
(2) Hydraulically bonded refractory mortar yog ib qho kev sib xyaw ua ke ntawm cov khoom siv hluav taws xob zoo thiab cov khoom siv hydraulic (cement) uas ua lub luag haujlwm tseem ceeb hauv kev khi. Lub xeev tus me nyuam tsuas yog qhuav thiab siv tau tom qab ntxiv dej. Tsis tas yuav cua sov thaum hardening.
(3) Chemically bonded refractory mortar yog ib qho sib xyaw ua ke ntawm refractory nplua aggregate thiab tshuaj binders (inorganic, organic-inorganic, organic). Nws yog xa mus rau hauv slurry los yog qhuav daim ntawv thiab hardens hauv qab no lub ceramic bonding kub. Raws li lub hardening kub, hom refractory mortar no yuav muab faib ua ob hom: cua-hardening thiab thermo-hardening. Air-hardening refractory av nplaum feem ntau yog tsim los ntawm cov khoom cua-hardening xws li iav dej. Kub-hardening refractory mortar feem ntau yog tsim nrog kub-hardening binders xws li phosphoric acid los yog phosphate. Tom qab hardening, qhov no thermosetting refractory mortar tsis tsuas yog muaj lub zog siab ntawm ntau yam kub, tab sis kuj muaj cov yam ntxwv ntawm me me shrinkage, nruj pob qij txha, thiab muaj zog corrosion kuj.
