Description
Technical field
The present invention relates to ceramic, be specifically related to a kind of production method of Attapulgite porous ceramics drain casting method.
Background technology
Development along with science and technology and suitability for industrialized production, problems such as the energy, resource, the disposal of three wastes come into one's own more, porous ceramic film material because have that porosity height, air permeance resistance are little, controllable bore diameter, cleaning and regeneration is convenient and characteristics such as high temperature resistant, high pressure, resistant to chemical media corrosion, be used widely in fields such as oil, chemical industry, pharmacy, food, environmental protection and water treatments at present.Especially high-tech sectors such as biochemical industry, fine chemistry industry, energy and material develops rapidly, liquid, solid Research of Separation Technique and exploitation are proposed higher requirement, and high score more and more causes people's attention from the porous filtering technology and the porous ceramics filtering material of precision, high operational efficiency.
The ceramic body that the slip casting method shaping is produced is strict to the specification of quality of mud, the mud that casting is used must have good flowability, thixotropy, stability and perviousness, is guaranteeing under the mobile prerequisite, water ratio is low as far as possible, also requires not contain in the mud bubble.
The mud that the drain casting method is used, its relative density is smaller during than solid casting, the stability requirement height of mud, degree of thickening is unsuitable too high, the particle fineness of mud is thinner, in common ceramic process, be easy to reach above-mentioned condition, but for producing the porous ceramics product, not only require the natural generating portion pore of energy in the base substrate making processes, also will avoid the too high meeting of sintering temperature to make part holes sealing or disappearance, sintering temperature is too low, causes the intensity of ceramic product low, therefore raw and auxiliary material and the production method to porous ceramics has strict requirement, need take into account the void content and the intensity of ceramic product.
Summary of the invention
The objective of the invention is to overcome weak point in the prior art, a kind of production method of Attapulgite porous ceramics drain casting method is provided.
The production method of Attapulgite porous ceramics drain casting method is: will stir to mud after the batch mixes and leave standstill earlier, drying, the demoulding, drying, oven dry, middle temperature are burnt till with carrying out in the slow injection model of the mud after leaving standstill, middle high temperature burns till with high temperature and burns till the stage, base substrate after burning till slowly cools off, and is packaged as the finished product of Attapulgite porous ceramics.
The batching of Attapulgite porous ceramics drain casting method is made up of attapulgite clay, ripe flint clay, diatomite, plant stalk powder, coal grain, micronized polyethylene alcohol powder, yellow soda ash and water.
Attapulgite clay be a kind of layer of chain-like structure contain Shuifu County's zeopan clay mineral, crystal is needle-like, fibrous or fiber collection shape because the inner porous of attapulgite clay road, specific surface is big, can reach 500m
2More than/the g, help improving the porosity in the porous ceramic articles.
Attapulgite clay soil property exquisiteness has oily soapy, and light weight, property are crisp, and fracture is conchoidal or irregular shape, and water-absorbent is strong, tool viscosity and plasticity-when wet, and its viscosity can reach more than the 3000mPas, helps the bonding between the starting material; Magnesium oxide in the attapulgite clay can weaken in the ceramic base substrate because the yellow that Fe and Ti compound are produced, and promotes the translucency of porcelain base, improves the physical strength of base substrate.
Attapulgite clay has unique dispersing property, suspension is met dielectric medium and do not produced flocculation sediment, and dry post shrinkage is little, does not produce be full of cracks, and has good, the high temperature resistant and anti-good properties such as saline and alkaline of thixotropy;
Also contain a spot of hydromica, quartz, feldspar, kaolinite, sepiolite and opal in the attapulgite clay, these compositions are used for developing the Attapulgite expensive goods and belong to the impurity class, be to need to get rid of through the screening of purifying, and in the present invention, these compositions are the plasticity-that helps regulating Attapulgite porous china clay in powder, reduce the dry shrinkage of base substrate, shorten time of drying and prevent blank deformation.
Flint clay is the multiple mixture that contains aluminosilicate, main chemical compositions is silicon-dioxide and two kinds of oxide compounds of aluminium sesquioxide, ripe flint clay is that the flint clay raw ore forms after high-temperature calcination, ripe flint clay whiteness and luminosity are good, it is even to have quality, compact structure, volume stability, the refractory temperature high strength is big, in water, be difficult for disperseing, plasticity-is hanged down and characteristics such as water-intake rate is little, ripe in the present invention flint clay is used for improving the content of the aluminium sesquioxide of Attapulgite porous china clay in powder, it is low to avoid into the porcelain temperature, reduce the distortion that porous ceramic articles produces when burning till, can prevent that also porous ceramic articles from producing the atrophy in aperture in sintering process.
Diatomaceous mineral composition mainly is opal and mutation thereof, secondly is clay mineral-hydromica, kaolinite and mineral chip, and quartz, feldspar, biotite and organic matter etc. are arranged in the mineral chip; Diatomite has exquisiteness, loose, light weight, porous, water-absorbent and the strong characteristics of perviousness, helps improving porous ceramic articles mesoporosity rate.
Yellow soda ash is used for that in the present invention Attapulgite porous china clay in powder batching is carried out sodium modification to be handled, and can improve the plasticity-and the adhesive property of Attapulgite porous china clay in powder.
Plant stalk powder is the flour of wearing into after being dried by timber tankage, paddy rice, wheat, rape, seeding corn and other crops straw and accessory substance, be a kind of pore-forming material in the present invention, use Attapulgite porous china clay in powder to make the base substrate of porous ceramics, after the intravital plant stalk powder of base produces the burning volatilization in sintering process, in base substrate, stay less pore.
The coal grain adopts stone coal to pulverize, and is a kind of pore-forming material in the present invention, uses Attapulgite porous china clay in powder to make the base substrate of porous ceramics, after the intravital coal grain of base produces the burning volatilization in sintering process, stays bigger pore in base substrate.
Micronized polyethylene alcohol powder is soluble in water, is a kind of softening agent in the present invention, helps increasing the cohesiveness and the plasticity-of Attapulgite porous china clay in powder.
The present invention is achieved by following technical proposals:
