High alumina composite cib
High alumina composite cib
Khoom zoo: siab refractoriness, muaj zog corrosion tsis kam rau acid thiab alkaline slag, siab kub txhua yam muaj zog, siab zog hnav tsis kam, tev tawm ua haujlwm, kub poob siab tsis kam.
khoom piav qhia
High-aluminium composite brick A sintered high-aluminium composite cib yog tus yam ntxwv los ntawm txheej txheej, uas yog tsim los ntawm txheej txheej ua haujlwm thiab txheej rwb thaiv tsev cua sov. Cov cib ua ke yog txheej txheej tsim los ntawm txheej txheej ua haujlwm thiab txheej txheej cua sov, thiab muaj cov hluav taws tiv taus zoo thiab tiv thaiv tshav kub. Cov txheej txheem ua haujlwm thiab txheej rwb thaiv tsev cua sov yog cais ua pawg thiab sib xyaw thaum npaj, thiab tom qab ntawd tsim thiab rho tawm ua ke. Cov txheej txheem ua haujlwm ntawm cov cib sib xyaw muaj lub zog ua kom muaj zog nrog txheej txheej cua sov. Cov txheej txheem ua haujlwm muaj qhov kub thiab txias tiv taus zoo, kua qaub thiab alkali tsis kam, txhuam tsis kam, siab zog, zoo thermal poob siab ruaj khov, ua kom sov tau zoo ua tau zoo thiab muaj zog ntawm txheej txheej cua sov. siab. Cov cib sib xyaw ua ke tuaj yeem ua tau raws li cov kev xav tau thiab siv qhov xav tau ntawm lub qhov cub tawg, tuaj yeem paub txog kev txuag hluav taws xob thiab txo qis kev siv, thiab ua kom lub neej ua haujlwm ntev ntawm lub qhov cub tawg. Txoj kev npaj yog kev tshawb fawb thiab tsim nyog, yooj yim thiab yooj yim rau siv, thiab tsim nyog rau txoj siv hluav taws thiab siv txoj siv lim ntawm lub qhov cub loj loj. Ib qho ntxiv, alumina cov khoom siv cib tau siv dav hauv ntau yam lag luam xws li hluav taws xob, hlau, hlau tsis yog hlau, petrochemicals, iav, cement thiab cov khoom siv hauv tsev.
Kev piav qhia ntawm high-aluminium composite bricks:
1. Nta thiab siv:
Nws muaj qhov ua kom rov zoo dua qub, muaj zog tiv taus xeb rau cov kua qaub thiab alkaline slag, thiab cov cuab yeej siv zog siab ntawm qhov kub thiab txias, yog li nws tau siv dav hauv kev lag luam hlau thiab lwm yam rauv taws. Nws yog tsuas yog siv rau sab hauv ntawm ntau yam khoom siv hluav taws xob cua sov xws li lub qhov cub hluav taws xob, lub qhov cub tawg, lub qhov cub tawg kub, cov tub rog, cov nruas hlau, cov tsheb nqaj hlau, cov cement kilns, cov iav qhov cub, thiab lwm yam. , xis mas thiab lwm yam lag luam.
2. Cov khoom tshwj xeeb: tus qauv, dav thiab tshwj xeeb zoo li tus, tshwj xeeb zoo li tus thiab tshwj xeeb zoo li tus cib.
3. Cov cib ua hluav taws kub yog cov khoom siv hluav taws xob uas muaj cov yam ntxwv thiab qhov loj me. Cov cib hluav taws kub hnyiab muaj cov cua sov zoo thiab tsim nyog rau cov cua kub qhov cub tawg, ntau lub tshuab rhaub dej kub, cov nplaim taws, cov pa luam yeeb, thiab lwm yam. thiab ntxiv rau. Refractory cib feem ntau muab faib ua ob hom, tsis hloov pauv cov duab thiab cov duab puab. Cov khoom siv refractory uas tsis hloov pauv: tseem hu ua castable, nws yog cov hmoov sib xyaw ua ke uas muaj ntau yam sib sau ua ke lossis sib sau ua ke thiab ib lossis ntau tus khi. Thaum siv, nws tau sib xyaw nrog ib lossis ntau cov kua thiab sib tov sib npaug. Qhia kom muaj kev txav mus los. Cov khoom siv ua cov khoom siv hluav taws xob: feem ntau ua cov cib ua hluav taws xob, cov duab uas muaj cov cai tswj hwm, thiab nws kuj tseem tuaj yeem ua tiav ib ntus raws li xav tau thaum tsim thiab txiav.
