Detailed Description
The technical solution of the present invention is further described below in specific embodiments.
A high-pressure grouting ceramic slurry comprises a ridge raw material group and a plastic raw material group; the ridge raw material group comprises the following raw materials in parts by weight: 6-13 parts of pyrophyllite, 6-15 parts of Jiangxi porcelain stone, 3-10 parts of raw ore mica sheet, 2-8 parts of potassium-sodium sand, 2-9 parts of sodium sand and 3-10 parts of waste porcelain; the raw materials of the plastic raw material group comprise: 1-8 parts of magnesium mud, 6-15 parts of Fujian kaolin, 4-9 parts of washing mica powder, 2-6 parts of washing black mud, 8-14 parts of Chaozhou washing mud, 3-6 parts of North sea white mud and 2-6 parts of raw ore black mud; the weight part ratio of the ridge raw material group to the plastic raw material group is 0.7-1: 1.
Compared with the high-pressure grouting ceramic slurry in the prior art, the high-pressure grouting ceramic slurry disclosed by the invention has the advantages that the content of clay plastic raw materials is reduced, the content proportion of ridge raw materials such as pyrophyllite, Jiangxi porcelain stone and the like is increased, the filterability and permeability of the high-pressure grouting ceramic slurry can be improved, the strength and thermal shock resistance of a finished product can be improved, moisture contained in the slurry during grouting can be smoothly filtered and discharged by a model, the high-pressure grouting ceramic slurry with optimized components is simpler in raw material components, better in batching operation convenience, better in flowability, stability and filterability, better in thixotropy can be further obtained by adjusting relative viscosity, the slurry absorption speed during high-pressure grouting can be improved, and better forming speed and production efficiency are realized.
It is worth explaining that the raw mica sheet is sheet-shaped, unprocessed and belongs to a ridge raw material; and the washed mica sheets are manually crushed and processed, and quartz of associated minerals which are not crushed is separated out, so that the washed mica sheets belong to plastic raw materials.
The weight part ratio of the ridge raw material group to the plastic raw material group is 0.7-1:1, so that the filterability and drainage speed of the high-pressure grouting ceramic slurry can be increased, and the forming speed is increased; the ridge raw material accounts for too high, the weight part ratio of the ridge raw material group to the plastic raw material group is more than 1:1, and the demolded blank is easy to slightly shake and has a broken corner; the proportion of the ridge raw materials is too low, the weight part ratio of the ridge raw material group to the plastic raw material group is less than 0.7:1, the slurry is easy to thicken, the filterability is not high, the forming speed is slow, the hydrophobicity is not timely, and the green body is easy to soften and collapse.
Further, the particle size of the waste porcelain is less than or equal to 10mm, and the relative viscosity of the high-pressure grouting ceramic slurry is 70-100 Pa.s.
The particle size of the waste porcelain is less than or equal to 10mm, the adverse effect caused by overlarge particle size of waste porcelain slurry particles can be avoided, so that the defects of easy layering, low blank receiving rate, sintering layering bulge and the like generated during blank forming of high-pressure grouting ceramic slurry are avoided, and the recycling of the waste porcelain has better environmental protection significance. The firing performance of the slurry can be improved by adding part of waste porcelain to replace porcelain stone, and the ceramic slurry is not easy to crack after being discharged from a furnace.
The relative viscosity is measured by an Engler viscometer or a torsional viscometer.
The ceramic slurry is a slurry, the slurry is a dispersion system formed by suspending solid materials mainly comprising clay in water, the flow of the slurry belongs to non-Newtonian flow, the numerical value of the relative viscosity is easy to change and is unstable, so the relative viscosity in the pulping process can only be referred to judge the relative stability of the slurry.
Relative viscosity is a measure of the internal resistance to relative movement of different parts of a fluid. When the shear stress per unit area between two planes of relative fluid motion is proportional to the velocity gradient, the flow is newtonian and its viscosity coefficient is constant. However, for suspensions, especially slurries with high solids content or non-spherical particles, to deviate from newtonian flow, the applied shear stress must exceed a certain minimum value before the fluid flow begins after the yield value. Mainly because of the three-dimensional lattice structure formed among particles in the slurry system, the system must be firstly damaged to flow, and the unstable internal structure is point contact. Thus, the slurry has high thixotropy.
The high-pressure grouting ceramic slurry with the relative viscosity of 70-100 Pa.s has good thixotropy, is convenient to transport and cannot be softened and collapsed by slight vibration. The viscosity change of the slurry after being stored for a certain time is not too large, otherwise, the slurry is inconvenient to convey and store, the slurry is easy to thicken and inconvenient to inject if the thixotropy of the slurry is too large, and the slurry is easy to collapse when a green body is molded if the thixotropy of the slurry is too small.
And the slurry sucking speed cannot be increased when the relative viscosity is too high, and collapse or incomplete defect of a blank is easy to occur during grouting when the relative viscosity is too low.
Further, the slurry suction speed of the high-pressure grouting ceramic slurry during grouting is 0.2-0.25 ㎥/h.
The slurry suction speed of the high-pressure grouting ceramic slurry is 0.2-0.25 ㎥/h, and the ceramic blank has no incomplete appearance or deformation and collapse after the ceramic blank mold is grouted. Compared with the prior art before improvement, the pulp suction speed is greatly improved by 0.12-0.15 ㎥/h, and the forming speed and the production efficiency can be better.
Further, the invention also provides a preparation method of the high-pressure grouting ceramic slurry, which is characterized by comprising the following steps of:
s1), preparing the raw material components of the high-pressure grouting ceramic slurry according to the weight parts to prepare a mixture;
s2), wherein the waste porcelain is added as a raw material and needs to be crushed, and the particle size of the waste porcelain is less than or equal to 10 mm;
s3) adding water into the mixture, uniformly stirring, carrying out ball milling by using a ball mill, and confirming that the viscosity of ball-milled slurry reaches a set range value through detection to prepare slurry;
s4) screening the slurry to obtain the high-pressure grouting ceramic slurry.
The preparation method has simple process, better flow operation operability and low production cost.
Further, the step of crushing the waste porcelain in step S2 is as follows:
p1) carrying out coarse crushing on the waste porcelain by using a jaw crusher until the particle size of the waste porcelain is 10-20 mm; p2) adopting a hammer mill to finely crush the waste porcelain material prepared in the step P1 until the particle size of the waste porcelain material is less than or equal to 10 mm;
p3) screening the waste porcelain material obtained in the step P2 by a drum screen to obtain the waste porcelain with the grain size less than or equal to 10 mm.
The waste porcelain can ensure that the crushed granularity is relatively uniform through coarse crushing and fine crushing, can obtain better utilization rate, and removes the overlarge part of the grain diameter through a rolling screen so as to avoid influencing the efficiency and the effect of ball milling.
Further, the rotation speed of the ball mill in the step S3 is 13-16r/min, and the ball milling time is 8-10 h.
The low-speed ball milling of 13-16r/min is adopted, and the aim of completely mixing and slurrying the raw materials is achieved through ball milling of 8-10 h. Too fast or too short time, the poor blank forming collapse is easy to occur when the raw material is not completely mixed and slurried.
Further, the water adding amount in the step S3 is 30 to 40 parts by weight.
The water addition in step S3 is for the purpose of slurrying, so the amount of water added should not be too much as it can be slurried.
Further, the slurry particles in step S3 have a particle size of less than 30 μm, and particles with a particle size of less than 20 μm account for more than 75% of the total weight.
The particle size of the slurry particles in the step S3 is less than 30 μm, and the particles with the particle size of less than 20 μm account for more than 75% of the total weight. The prepared slurry has better fluidity, is not easy to scratch and has good stability. The small particles have high processing difficulty and no economic benefit, and the micropores of the die are easily blocked.
Further, the sieving process in step S4 includes: and (3) screening and deironing by using a three-dimensional rotary vibration screen, ageing the mixed slurry after screening and deironing for 7 days, and then screening and deironing the aged mixed slurry again.
After sieving and removing iron, secondary refining is carried out, namely aging and secondary sieving and removing iron are carried out, the aging can make the high-pressure grouting ceramic slurry more uniform, and the plasticity, the suspension property and the fluidity are improved; and sieving again to remove iron, and further removing iron-containing substances and other impurities.
Further, the aperture of the screen of the three-dimensional rotary vibration screen is 80 meshes.
After the slurry is filtered by the rotary vibrating screen with the aperture of the screen mesh of 80 meshes, the slurry particles with the particle size of less than 20 microns account for more than 75 percent, and the slurry particles are distributed to the middle 10 microns and concentrated, so that the defects of easy layering, low blank yield, sintering layering and bulging and the like during the molding of ceramic blanks manufactured by high-pressure grouting due to large particle size of the slurry particles can be avoided.
