Description

Sintered product of soil

Technical Field

The invention relates to the field of green environment-friendly ecological materials, and particularly provides a soil material sintered product.

Background

The ball clay is a clay mineral containing microcrystalline kaolinite and alpha-quartz particles as main mineral components. Or ball clay, a refractory material. Ball clay is a highly plastic clay rich in organic matter.

The ball clay is very few in the world, a large amount of ball clay minerals exist in Jilin, so the transportation cost is relatively low, the traditional clay sintered product such as pottery needs to be added with various additives to achieve the desired effect, the cost is relatively high due to various additives, the technological process is relatively complex, the processing period is relatively long, the forming is relatively troublesome, the additives possibly bring adverse effects, and the traditional clay sintered product such as pottery is easy to permeate for a long time.

Disclosure of Invention

In view of the above, in order to solve the above problems, the present invention aims to provide a sintered product of earth materials after mixing ball clay and shale.

The technical scheme provided by the invention is as follows: a soil material sintered product comprises the following components in percentage by weight: 60% -70% of ball clay; 30-40% of shale.

Preferably, the ball clay is 60-65% by weight.

Preferably, the weight percentage of the shale is 35% -40%.

Further preferably, the product is prepared by mixing the raw materials according to the above proportion.

The soil material sintered product provided by the invention has the advantages that the raw materials are locally adopted, the transportation cost is saved, the cost is saved, no additive is added, the product is green and safe, the texture is fine, no impurity is contained, the permeability is good, and the forming is convenient.

Drawings

Other features, objects, and advantages of the present invention will become more apparent from the following detailed description of the invention when taken in conjunction with the accompanying drawings and embodiments:

FIG. 1 is a process flow diagram of a soil sintered product according to the present invention.

Detailed Description

The invention will be further explained with reference to specific embodiments, without limiting the invention.

As shown in figure 1, the invention provides a soil sintered product, which comprises the following components in percentage by weight: 60% -70% of ball clay; 30-40% of shale.

The weight percentage of the ball clay is 60-65%.

The weight percentage of the shale is 35-40%.

The product is prepared by mixing the raw materials according to the proportion.

Specifically, the soil sintered product is processed by the following steps before being formed, referring to fig. 1, including:

step 1, selecting shale, washing and crushing the shale;

step 2, selecting ball clay;

step 3, weighing and proportioning the materials obtained in the step 1 and the step 2;

step 4, performing wet ball milling on the mixed material obtained in the step 3 to obtain slurry;

step 5, filtering and deslagging the inner pulp obtained in the step 4;

step 6, filling the slurry obtained in the step 5 into a slurry tank for later use;

step 7, ageing the materials in the step 6;

step 8, injecting the aged raw materials in the step 7 into a mold for molding;

step 9, drying and demoulding the formed product in the step 8 properly;

step 10, the temperature of demoulding in step 9 is sintered at preferably 1100-1250 ℃ and preferably 9-11 hours.

Example 1, testing after selecting a combination of ball clay 70% and shale 30%:

table 1 shows the performance parameters of the sintered earth material article of example 1:

example 2, testing after selecting a combination of 62% ball clay and 38% shale:

table 2 shows the performance parameters of the sintered earth material article of example 2:

example 3, testing after selecting a combination of 60% ball clay and 40% shale:

table 3 shows the performance parameters of the sintered earth material article of example 3:

example 4, testing after selecting a combination of 65% ball clay and 35% shale:

table 4 shows the performance parameters of the sintered earth material article of example 4:

example 5, testing after selecting a combination of 67% ball clay and 33% shale:

table 5 shows the performance parameters for the sintering of the soil of example 5:

according to the examples 1-5, the soil sintered product has water absorption rate floating in a proper interval between 60% -70% of ball clay and 30% -40% of shale, and the national requirement can be met as long as the water absorption rate is less than 1, and according to the table 1-5, the water absorption rate in the interval between 60% -65% of ball clay and 35% -40% of shale reaches a relatively stable effect basically at 0.56%, so that the soil sintered product can be preferably used in the interval between 60% -65% of ball clay and 35% -40% of shale.

Table 6 shows the results of the plastic property measurements of the clay in the local area (Jilin):

for samples 1 or 2 which only represent different grades of ball clay, according to the specification, when the plasticity index is greater than 17, the clay is clay which is sticky soil with few sand grains and has better plasticity because water cannot easily pass through the clay, and the plasticity of the ball clay in the local area is higher as can be obtained through table 6.

The products mixed by the raw materials in the proportion are products or articles in various forms prepared according to the proportion interval, and the products or the articles are all included in the protection scope of the application.

Example 6, in which the product after sintering in step 10 also satisfies the requirements in terms of water absorption per se, in the case of bottles, if a better texture is desired in the interior of the bottle, the product can be connected to the inside of the bottle by means of spraying or glazing, and if a good appearance is desired, the product can be connected to the outside of the bottle by means of external spraying or glazing.

It should be noted that the addition amount of the ball clay and shale in the sintered earth product of the present invention has various embodiments, and the combination with the formulation of other raw materials has various embodiments, which are not exemplified herein, so the above examples are only a few realizable embodiments, the scope of the present invention is not limited to the above examples, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present invention.
