Abstract
A porous ceramic body is prepared through such steps as mixing granular basic ceramic material with organic adhesive, uniformly stirring, die pressing to shape, drying, and high-temp sintering to make the ceramic particles be sintered together. Its resultant porous ceramic features optimal structural strength, low cost, higher permeability and filtration.
Description
The present invention relates to the ceramic technology field, refer in particular to method for making of a kind of porous ceramic body and products thereof.
Ceramic body is widely used in agricultural and plants the filter material of the medium of planting, agricultural fertilizer, pesticide slow-release carrier, fishery cultivating water quality, cultures the filter material that the filter material of make the bed at the bottom of the pond material, general family, industry, off gas treatment and catalyst carrier and metal casting are used.The method for making of ceramic body is divided into three kinds substantially:
First kind is the method for making of traditional monomer-type ceramic body, make imporous ceramic particle body by ceramic base material with weight or other modes, it supplies the usefulness of planting or filtering of planting of agricultural fishery mostly, because this its structure of monomer-type ceramic body is not had a porousness, and its whole surface area is less, cause permeability reduction, filter effect is relatively poor etc., so moisture and air can't be kept somewhere on ceramic particle, farming is planted and the beneficial bacterium of the decomposition fertilizer of fishery grows up and can't provide the moisture of suitable foot and air to supply with to help, value and effect in the use are relatively poor, cause inconvenience and puzzlement in the use.
Second kind is the ceramic body method for making that is extruded into pattern, and it mainly is that ceramic base material mixing tackiness agent is formed a mixture, and with the honeycomb structure of this mixture via the vertical section net, extruding is the ceramic body of strip.The ceramic particle body of its more above-mentioned traditional monomer-type has preferable perviousness and filterableness, can keep more water and air, uses the situation that goes up easy generation breakage but this kind is extruded into the ceramic body of pattern, so the efficient of using is lower.
The third is the porous ceramic bodies method for making of soaking paste formation type, it is with the cavernous body dipping ceramic mud of foaming, and then after extruding, remove unnecessary ceramic mud, then carry out drying, and remove this polymer sponge body with high temperature or chemical agent, make the porous ceramic body of tool, the effect of its use is better than above-mentioned two kinds, but, cause integral intensity relatively poor, so easily produce breakage when using because that its hole distributes is more closely knit, and because hole is too trickle, the situation that Yi Sheng blocks cause work-ing life shorter, and cost is comparatively high.
The object of the present invention is to provide method for making of a kind of porous ceramic body and products thereof.With granular ceramic base material and an amount of organic binder bond mixing and stirring, be molded into required shape, drying, again through high temperature sintering, make the surface clinkering of particulate state ceramic base material become porous ceramic body, reach and have better structural strength and with low cost, and have the purpose of perviousness and filterableness.
The object of the present invention is achieved like this: 1, a kind of method for making of porous ceramic body is characterized in that this manufacture method comprises the steps:
(1) puddle bonding:
Ceramic base material is ground into particulate state, adds an amount of organic binder bond mixing and stirring, this particulate is neglected the required pore size of ceramic body greatly and difference;
(2) compression molding:
(1) mixture is inserted in the mould of desired shape, impose the gravity moulding;
(3) drying:
With the forming composition of (two) universal method drying;
(4) sintering:
The drying and moulding thing placed carries out sintering in the high temperature sintering kiln, with between each bonding ceramic particle that depends on fully clinkering be integral, each intergranular careful hole constitutes porous open hole slot, this sintering temperature is 300-1000 ℃, the time is 30-60 minute;
(5) finished product: sintering after the finishing and the check, eligible is a finished product.
The add-on of this organic binder bond is advisable so that granular ceramic base material is bonded to each other.
That this drying means comprises is air-dry, dry or dry.
A kind of porous ceramic body, the porous ceramic body that forms by sintering behind most ceramic particle mould-formings with careful open hole slot.
Major advantage of the present invention is: have better structural strength and with low cost, and have the effect of perviousness and filterableness.
The present invention is further described below in conjunction with preferred embodiment and accompanying drawing:
Fig. 1 is a manufacturing process synoptic diagram of the present invention;
Fig. 2 is a product schematic perspective view of the present invention;
Fig. 3 is a product diagrammatic cross-section of the present invention;
Consult Fig. 1, manufacture method of the present invention comprises the steps:
(1) puddle bonding:
Ceramic base material is ground into particulate state, add an amount of organic binder bond mixing and stirring, this particulate is neglected the required pore size of ceramic body greatly and difference, when needing macrovoid, be ground into larger particles, when needing the fine porosity, be ground into than small-particle, the add-on of this organic binder bond is advisable so that granular ceramic base material is bonded to each other;
(2) compression molding:
(1) mixture is inserted in the mould of desired shape, impose the gravity moulding;
(3) drying:
With the forming composition of (two) universal method drying, that this drying means comprises is air-dry, dry or dry;
(4) sintering
The drying and moulding thing placed carries out sintering in the high temperature sintering kiln, with between each bonding ceramic particle that depends on fully clinkering be integral, each intergranular careful hole constitutes porousness, this sintering temperature is 300-1000 ℃, the time is 30-60 minute;
(5) finished product:
Sintering after the finishing and the check, eligible is a finished product.
Consult Fig. 2-Fig. 3, the ceramic body made from method of the present invention 2 adds tackiness agent 4 bonding mould-formings for most ceramic particles 1, porous ceramic body 2 through sintering formation with careful open hole slot 3, it has preferable structural strength, 1 of each particle has bigger open hole slot 3 continuously, ceramic body 2 has good penetration, filters and give birth to and adsorptivity, whole surface-area is bigger, exactly the moisture of enough maintenance appropriateness and air are in ceramic product 2, the beneficial bacteria growing space of decomposing fertilizer is provided, is applicable to agricultural cultivation and various Filters.
