Raws li ob sab phlu ntawm lub cub qaum, nws tsis yog tsuas yog yuav rau cov yaig ntawm cov khoom kub hauv cov khoom kub thiab plua plav roj av, tab sis kuj yuav tsum tau ua kom zoo thermal rwb thaiv tsev ua haujlwm. Tom qab xyoo ntawm cov kev tshawb fawb tau zoo thiab kev txhim kho lub zog ua kom muaj zog, thiab cov khoom siv thermal ua tau zoo, ua kom cov kev txhim kho ntawm kev txhim kho ntawm kev ua hluav taws xob hauv lub Kiln. Ib qho ntxiv, peb qhov kev tshwj xeeb tsim hauv cib hom thiab Masonry txoj kev lees paub qhov kev ua tau zoo tag nrho ntawm tag nrho ob lub ntsej muag. Tom qab tau siv nyob rau hauv ntau pellet, txiv qaub, roj av coke, hmoov dawb, nws tau ua tiav lub zog zoo-txuag hluav taws xob thiab lub neej pabcuam ntau tshaj 2 xyoos. Nws tau txhim kho cov kev pab nyiaj txiag rau cov neeg siv thiab cov nqi tswj xyuas tau zoo, thiab tau raug lees paub thiab qhuas los ntawm cov neeg siv.
Teb cov tshuaj xilns feem ntau yog tsim nrog ib-txheej siab-aluminium lossis alkaline cib. Vim yog lawv lub siab thermal conductivity, lub kiln plhaub kub yog siab (txog 300 degree), ua rau muaj kev kub ntxhov loj thiab muaj zog siv hluav taws xob. Txawm hais tias ob-txheej los yog ntau-txheej masonry cov ntawv xws li rwb thaiv tsev txheej yuav txo tau cov txheej txheem cloal, thiab xoob, muaj kev sib cav sib ceg, thiab cov thwv cib tsis zoo los poob lossis txawm vau. Kev siv cov kab cib uas sib xyaw muaj peev xwm daws tau cov teeb meem no. Cov txheej hnyav thiab txheej txheem ib nrab yog ua ke rau hauv ib qho, uas tsis yog txo qis lub ntsej muag kub, tab sis kuj ua kom muaj kev ncaj ncees ntawm lub cev hauv lub caij sib hloov thaum lub sijhawm sib hloov thaum lub sijhawm sib hloov. Nyob rau tib lub sijhawm, nws kuj tuaj yeem txo qhov hnyav ntawm cov kab, uas tau txais txiaj ntsig rau kev ua haujlwm ntawm lub teb chaws cub.
Cov khoom lag luam
Tus yuam sij rau kev txhim kho cib nyob hauv kev ruaj ntseg thiab lub zog ntawm kev sib koom tes ntawm cov txheej hnyav thiab lub teeb txheej txheem. Los ntawm kev sim, nws paub tias qhov hnyav thiab lub teeb ci sib xyaw ua ke yuav tsum ua kom tau raws li ob qho xwm txheej hauv qab no:
(1) Cov ntaub ntawv ntawm hnyav thiab Semi-lub teeb Matrix siv rau kev sib txuas yuav tsum muaj zoo ib yam. Nws yog qhov nyuaj kom tau txais cov khoom zoo sib xyaw zoo thaum ob yam khoom sib txawv ntawm qhov sib txawv loj yog qhov sib xyaw.
(2) Qhov sib txawv hauv cov khoom ntom ntom ntawm cov khoom siv hnyav thiab ib nrab teeb yuav tsum tsis txhob loj dhau. Qhov sib txawv loj hauv cov ntom ntom ntom yuav ua rau tawg ntawm kev sib koom ua ke vim tsis sib haum hluav taws xob shrinkage. Tom qab ntau qhov kev ntsuam xyuas, lub ntim ntom ntawm lub teeb khoom zoo nrog mullite alkali-resistant bricks yog qhov feem ntau haum rau ntawm 1.8g / cm3.
1. Composite cib tsim
LOJ COLNING CLOCKS feem ntau ua nrog rab riam-ntug cib Lub teeb ci semi-lub teeb ntawm cov cib ntau yog feem ntau 80mm tuab thiab sib xyaw ua ke nrog cov txheej txheej hnyav, raws li muaj nyob hauv daim duab hauv qab no.
2. Khoom Npaj Khoom
Cov ntaub ntawv hnyav thiab cov khoom siv teeb pom kev sib xyaw ua ke thiab muab faib ua ke thaum muaj 630T nias thiab ziab, raug rho tawm haujlwm rau 810. Cov txheej txheem kev sim ntsuas ntawm lub teeb txheej txheej ntawm cov cib cib hauv cov cib muaj teev nyob hauv qab no.

Qhov kev hloov kub ntawm kub hloov tau cov kev hloov pauv yog nqa tawm raws li qhov kub thiab txias ntawm 1200 degree hauv thaj chaw tua hluav taws thiab qhov chaw huab cua kub ntawm 30 degree. Lub cim Kiln lub ntsiab yog teev nyob rau hauv cov lus hauv qab no. Los ntawm kev suav, nws tuaj yeem pom tias kev siv cov cib ntau zaus tuaj yeem txo cov cua kub thiab txo cov cua sov noj ntau dua 5%.
