In one preferred embodiment, the density of cordierite is not less than 1.6g/cm3, water absorption rate is not higher than 2%.Violet Green stone density is too low, and the compactness of obtained saggar is poor, influences the intensity of saggar.Water absorption rate is excessively high, illustrates inside cordierite Porosity is higher, can equally influence the intensity of saggar.
Cordierite provided by the invention-corundum bollow ball saggar is mainly with kaolin, talcum, aluminium oxide, specified particle diameter The cordierite of corundum, the corundum bollow ball of specified particle diameter and specified particle diameter is raw material, wherein corundum, corundum bollow ball and cordierite Grain size the quality of saggar is influenced extremely important, grain size is excessive or the too small service life that can make saggar reduces, and only exists In specific particle size range the service life of saggar can just be made to reach optimal in the present invention;Above each raw material cooperates, and prepares The heat resistance and thermal shock resistance of obtained saggar are good, and saggar is less prone to the changes such as oxidation, decomposition, synthesis in use Reaction is learned, chemical stability is good, and is unlikely to deform, good stability of the dimension, and the pressure in saggar is relatively stable, is less prone to brokenly It splits, therefore, saggar has the advantages that service life length is low with use cost;In addition, each raw material sources are wide, cheap, therefore, The production cost of saggar is relatively low.
In one preferred embodiment, mainly it is prepared by the raw material of following mass parts:
9 parts of kaolin, 8 parts of talcum, 3.5 parts of aluminium oxide, grain size are not more than 46.9 μm of 25 parts of corundum, and grain size is not more than 50 parts of the corundum bollow ball of 1mm and 10 parts of the cordierite that grain size is 1-3mm.
The present invention also provides the preparation methods of above-mentioned cordierite-corundum bollow ball saggar, comprise the following steps:
Each raw material of formula ratio is uniformly mixed, then addition bonding agent is uniformly mixed again obtains mixture, mixture It can obtain the cordierite-corundum bollow ball saggar after being molded and burning till.
Above-mentioned preparation method processing step is simple, need to only be uniformly mixed each raw material, adds in after bonding agent and mixes again It is even, then after being molded and burning till to obtain the final product, simple processing, the cordierite being prepared-corundum bollow ball saggar have it is at low cost, The advantages of cost-effective and service life is long.
In one preferred embodiment, bonding agent includes spent pulping liquor, and the addition of spent pulping liquor is 3%-12%. Spent pulping liquor is the discarded object of paper mill discharge, includes lignin and its derivative, can combine each raw material, improves casket The intensity of alms bowl reduces the frictional force between each raw material, so as to improve the density of saggar.The addition of spent pulping liquor combines each raw material Property and its content depending on, be preferably 3%-12%, such as can be, but be not limited to 3%, 3.5%, 4%, 4.5%, 5%, 5.5%th, 6.5%, 7%, 7.5%, 8%, 8.5%, 9%, 9.5%, 10%, 10.5%, 11%, 11.5% or 12%;When adding Enter amount for 3.5% or 11% best results, therefore further preferably addition is 3.5% or 11%.
In the present invention, the addition of above-mentioned spent pulping liquor refers to that spent pulping liquor quality accounts for the percentage composition of mixture quality.
In one preferred embodiment, the addition of spent pulping liquor is 3%-4%, and mixture uses hydro-forming, It is burnt till after shaping.It is different by the liquid medium used, hydro-forming can be divided into hydraulic pressure shaping and oil pressure shaping, the present invention Preferably oil pressure is molded.
In another preferred embodiment, the addition of spent pulping liquor is 10%-12%, and mixture is used and struck out Type or vibrations extrusion forming, after shaping are dried, then reburn into first.
In one preferred embodiment, the temperature burnt till is 1360-1410 DEG C, soaking time 3-5h.Above-mentioned burning Into temperature for example can be, but be not limited to 1360 DEG C, 1365 DEG C, 1370 DEG C, 1375 DEG C, 1380 DEG C, 1385 DEG C, 1390 DEG C, 1395 DEG C, 1400 DEG C, 1405 DEG C or 1410 DEG C;Soaking time for example can be, but be not limited to 3h, 3.5h, 4h, 4.5h or 5h. The above-mentioned temperature burnt till fully has considered the chemical composition and its performance of each raw material, when the temperature burnt till is 1360-1410 DEG C, Can preferably reaction of formation object so that the performance of saggar is more stablized.Temperature is too low, and saggar can not fully be shunk, stomata Rate is higher, and density is relatively low;Phenomena such as temperature excessively high easy generation burning, make to generate micro-crack, strength reduction inside saggar.Heat preservation Time works in coordination with the temperature burnt till, and reaches optimal sintering effect jointly.
Calcining kiln used is burnt till above, can be shuttle kiln, tunnel oven, down-draft kiln or rolling tunnel kiln.
In addition, the present invention also provides above-mentioned cordierite-application of the corundum bollow ball saggar in Production of Ceramics.
Above-mentioned cordierite-corundum bollow ball saggar is applied in Production of Ceramics, due to the cordierite-corundum bollow ball casket Alms bowl has the advantages that at low cost, cost-effective and service life is long, therefore can effectively reduce the production cost of ceramics.
In order to illustrate more clearly of the present invention, with reference to preferred embodiment, the present invention is described further.
