Abstract
The present invention relates to a kind of is the microporous filtering ceramic of matrix with diatomite, belong to the micropore ceramics class, wherein contain the porosity height, the pottery that the diatomite that specific surface area is big, super-cell and all the other subsidiary material form through the pressure forming roasting, its goods the experiment proved that specific surface area is 1.5-2.5m
2/ g is that the 2-6 of traditional porous filter material doubly is zero with the filtering beverage of these goods, the total plate count of drinking-water, intestinal bacteria; Porosity is 60-80%, and filtration efficiency improves 1-2 doubly; Compressive strength reaches 600-1000kg/cm
2, and can in 0-400 ℃ of temperature range, normally use.
Description
The present invention relates to a kind of is the microporous filtering ceramic of matrix with diatomite, belong to the micropore ceramics class, its goods are suitable for beverage, wine brewing, medicine, edible oil, and all kinds of precisions of aspects such as drinking-water, petrochemical complex, metallurgical machinery lubricating oil, sewage disposal, sterile filtration fashionable dress are used.
In industrial solid-liquid separation, in the defecate and purify operation of liquid, filtration is an important means, filtering accuracy and efficient are directly connected to the quality and the cost of product, yet the plastics of present domestic and international application, corundum, the porous filter elements that titanium and metal powder metallurgy material are made, because these materials itself do not possess microvoid structure, the auxiliary material that adds pore-forming or whipping agent and so in materials processing and element manufacturing processed is many, complex process, big energy-consuming, the manufacturing cost height, the porosity of its goods low (being generally 20～30%), specific surface area is little (to be generally 0.2～0.5M
2/ g) cause filtering accuracy, efficient is low, and more do not reach the precision in the modern industry and the technical requirements of sterile filtration, thereby accurate sterile filtration is the difficult problem that urgency is to be solved, colleague's scientific and technical personnel are carrying out investigative test research, but all do not obtain satisfied result, as the ceramic porous filtering material of russian patent SU-753829, contain clay, kaolin, metal oxide diatom soil (2-20Wt%) and certain mineral filler are to be used for corrosive liquid, gas such as waste gas, the pottery of the filtering element of waste liquid, the pore diameter range of this material is 200～250 μ m.The component of above-mentioned pottery is many, and it is lower that cost height and diatomite are general component concentration, because material does not have microvoid structure, the aperture is bigger, therefore, can not satisfy precision, the sterile filtration requirement.
The object of the present invention is to provide a kind of simpler, energy consumption is low, component is few, cost is low, the porosity of its goods and specific surface area is big, intensity is high, broad application temperature range, and what can reach that precision and sterile filtration requires is the microporous filtering ceramic of matrix with diatomite.
The microporous filtering ceramic that repressed shaping and roasting of the present invention forms, contain poromerics and subsidiary material, its form and content (weight %) as follows:
Diatomite 60-80
Super-cell 18-40
Water glass 0.6-1.5
Soda ash 0.5-1.0
Described diatomaceous granularity is the 80-260 order
Microporous filtering ceramic of the present invention compared with prior art has following advantage and positively effect: manufacturing process is simple, component is few, energy consumption is little, reduce manufacturing cost, and its goods the experiment proved that specific surface area is 1.5-2.5M
2/ g be traditional porous filter material 2-6 doubly, beverage, the total plate count of drinking-water, the intestinal bacteria after these goods filter all are zero; Porosity is 60-80%, and its filtration efficiency improves 1-2 doubly; Compressive strength reaches 600-1000kg/cm
2, and can in 0-400 ℃ of temperature range, normally use, material cost is low, wide material sources.
Embodiments of the invention are described in detail, diatomite is a kind of novel material that just developed in recent years, diatom test spare is an amorphous silica, chemical property is stable, each purpose diatom shell is all very small, be generally the 2-30 micron, housing itself all has microvoid structure, the porosity height, specific surface area is big, therefore selecting diatomite for use is matrix, manufacture method is dried diatomite original ore routinely, pulverize, sizing machine is divided into different grades for making the micropore ceramics that the different accuracy filter criteria requires, prepare burden by the component concentration of prescription then and add water 15-25% in addition and stir, compression moulding, oven dry, the roasting shaping, assembling, the check warehouse-in, (weight %) is:
Diatomite 60-80
Super-cell 18-40
Water glass 0.6-1.5
Soda ash 0.5-1.0
Embodiment 1: ratio of components is (weight %) 100-260 purpose diatomite 80, super-cell 18.3, water glass 1.1, soda ash 0.6, add that water 22% stirs, compression moulding, through 200-220 ℃ of drying, again at 800-900 ℃ of roasting in kilns constant temperature 3 hours, integer, assembling, check warehouse-in
Embodiment 2: ratio of components is that (weight %) 80-100 purpose diatomite 70 diatom auxiliary agents 28.2, water glass 1.1, soda ash 0.7 add that water 25% adopts that the processing condition of embodiment 1 stir again, 820-920 ℃ of constant temperature 3 hours are adjusted in compression moulding, oven dry, maturing temperature, the integer storehouse that becomes to check in.
Embodiment 3: ratio of components be (weight %) 80 purpose diatomite 60,60 purpose diatomite auxiliary agents 38, water glass 1.2, soda ash 0.8 add water 25 with the processing condition of embodiment 1 stir, pressure forming, oven dry, roasting form, become to check in the storehouse.
Claims (2)
1, a kind of is the microporous filtering ceramic of matrix with diatomite, and the microporous filtering ceramic through the pressure forming roasting forms wherein contains poromerics and subsidiary material; The composition (weight %) that it is characterized in that this pottery is:
Diatomite 60-80
Super-cell 18-40
Water glass 0.6-1.5
