Description
Technical field
The present invention relates to a kind of ceramic packing, especially relate to a kind of high-strength light ceramic filler.
Background technology
Along with modern science and technology, development of modern industry, in the reaction tower of chemical industry and metallurgy industry, in the distillation tower of industrial treatment filtration and pharmaceutical industries, in the washing desulphurization of coking industry, light specific gravity, wettability and adsorptivity are strong, resistance to acids and bases is high, resistance to thermal shocks is good and ultimate compression strength is high, specific surface area is big all to need a large amount of having, the filler of surface difficult drop-off uses and processing intent to reach industry.At present, the packing variety of use is many, and the useful metal material is made, and useful timber is made, and also useful plastics and clay product are made, and in the filler of these kinds, though metal intensity height, its resistance to acids and bases is low, the manufacturing cost height; Though the wood pad low cost of manufacture, it is acid and alkali-resistance not, heatproof not, and ultimate compression strength is low; Though the plastic material filler can acid and alkali-resistance, heatproof not, ultimate compression strength is not high; Characteristics such as the relative above-mentioned materials filler of clay product filler has acid and alkali-resistance and resistance to thermal shocks is good, ultimate compression strength is also higher, can be made into porousness, and cost is also lower, thereby in above-mentioned technical field, obtained using widely.In clay matter filler, because each manufacturer's technical recipe is had nothing in common with each other, its performance also has bigger difference, porosity as filler varies, it is low that ultimate compression strength has height to have, analyze by inquiry and can learn, the subject matter that current clay matter filler exists: the one, the ultimate compression strength of clay matter filler is also not high, the generally the highest 12MPa that is no more than, filling surface falls piece easily and comes off during use, and the shock-resistant and polishing machine of filler is descended, thereby has shortened its filler work-ing life, reduce the absorption carrier surface forming biofilm property of gas-liquid mass transfer, increased the foreign matter content in the gas-liquid mass transfer; Be that clay matter filler porosity is also not high again, the whiteness of surface color is not enough, and anufacturability is not ideal enough.
Summary of the invention
The ultimate compression strength that exists at above-mentioned prior art medium clay soil matter filler is also not high, shock-resistant and polishing machine descends, and the whiteness of surface color is not enough, the dissatisfactory problem of anufacturability, the present invention proposes a kind of not only ultimate compression strength height, shock-resistant and good with polishing machine, long service life, and surperficial whiteness height, the better high-strength light ceramic filler of anufacturability.
The technical problem to be solved in the present invention, the technical scheme of being taked is: the high bauxite clay of described high-strength light ceramic filler, lime carbonate, talcum and five kinds of material components of husk chaff powder are prepared, described high bauxite clay, lime carbonate and steatitic weight percent are: high bauxite clay 75-85%, lime carbonate 8-15%, talcum 3-10%, three oxygen, two aluminium content are not less than 18% in the described high bauxite clay, described husk chaff powder add-on is high bauxite clay, the 10-20% of lime carbonate and three kinds of raw material gross weights of talcum, the weight percent of the Chemical Composition of described high-strength light ceramic filler is: silicon-dioxide 50-60%, aluminium sesquioxide 13-20%, calcium oxide 3-8%, magnesium oxide 10-16%, potassium oxide 1-3%, sodium oxide 0.3-0.8%, ferric oxide≤1%.
High bauxite clay, lime carbonate, talcum and husk chaff powder raw material that high-strength light ceramic filler of the present invention uses are big at China's storage capacity, and it is wider to originate, and can gather materials on the spot.Aluminium sesquioxide content is 18-25% in described high bauxite clay such as Jiangxi Province's Pingxiang City product clay, its high bauxite clay, and dioxide-containing silica is 50-70%; Described talcum major ingredient is silicon-dioxide and magnesium oxide.For improving the plastic manufacturability of filler, be convenient to extruding and make various complicated filler products, in above-mentioned component, can add an amount of plasticity-black earth (have better toughness with the hygrometric state filler, can push complicated filler and be advisable), produce black earth (popular name marine facies mud) as Guangdong.
High-strength light ceramic filler of the present invention is prepared by following processing step:
1, by various crude material technology formula weighings, pour in the ball mill, carry out ball milling,
2, the mixture behind the ball milling is sieved, carries out deironing with tramp iron separator,
3, after sieve, pour it into pulp storage tank,
4, with high pneumatic mortar machine it is sent into the mud cake that presses into suitable moisture content in the slip drying press, and carry out old,
5, become the mud section to store through the vacuum deairing machine white silk,
6, utilize the various product blanks of various mould extrusion moldings, dry naturally again and drying room is dried,
7, burn till under 1180-1260 ℃ of temperature with the coal gas shuttle kiln and be the finished product filler.
After testing, the main performance index of described high-strength light ceramic filler is:
Whiteness: 〉=55 ultimate compression strength:＞12MPa
Pile up voidage (m
3): 60-75% acid fastness: 〉=99%
Fastness to alkali:＞95% water-intake rate: 20-30%
Volume density: 0.8-1.18g/cm
3Igloss amount: 10-12%
Thermostability: test is 5 times in 220-20 ℃ of water, and packing samples does not have cracking phenomena.
The mechanism that high-strength light ceramic filler of the present invention forms is: why ultimate compression strength is also not high for current clay matter filler, be because aluminium sesquioxide content is lower in the existing clay matter filler, dioxide-containing silica is higher, thereby after burning till, microstructure mainly is free quartzy and a small amount of glassy phase in the clay matter filler, this structure is uneven dispersed the layout, thereby its ultimate compression strength is not high, and general ultimate compression strength is no more than 12MPa.When aluminium sesquioxide content is at 13%-20% in the clay matter filler, after burning till, microstructure in its filler is except that free quartzy and a small amount of glassy phase, some mullite crystal also, mullite crystal is tiny buttress shaft shape or needle-like and is evenly distributed in the matrix, and the mullite crystal high temperature creep is little, crystal expands evenly, resistance to chemical corrosion is strong, its matrix intensity is higher, general ultimate compression strength all can surpass 12MPa, thereby can improve ultimate compression strength, erosion resistance and the shock resistance of filler.
The present invention is because in its material component, improved aluminium sesquioxide content in the clay matter filler, make the microstructure of filler more reasonable, thereby can improve the ultimate compression strength of clay matter filler, make filling surface be difficult for falling piece and come off, the surface is acid and alkali-resistance and shock resistance more, helps gas-liquid mass transfer absorption biofilm, not only improve the work-ing life of filler, and reduced the foreign matter content in gas-liquid mass transfer again; Owing in filler, added calcium oxide and talcum, both improved the sintering character of filler, the whiteness of its filler is improved, be owing in filler, added the better husk chaff of pore-forming character powder again, its filler hole increases, and piles up voidage and improves, and packing volume density reduces.
