METHODS FOR MANUFACTURING CERAMIC WARE CLAY AND GLAZE USING FORESHORE MUD}

The present invention relates to porcelain bases and glazes, and more particularly to a method for producing porcelain bases and glazes by purifying the soil of the tidal flat.

Pottery is the first human being used as a tool for everyday life by using natural inorganic materials that are preserved on the earth. It is still an important part of the technology-intensive industry in our lives.

The history of ceramics originated from the Neolithic period around B.C.6000, and has led to the industrialization of today through various demands and changes.

Ceramics are classified into earth, ceramics, stone, and porcelain, and it is said that they have the main body of ceramics. The composition of general body is composed of three components of aged soil, silica, feldspar, composition ratio and firing temperature of each raw material. Depending on the ceramics, semi-magnetic nitrogen, and magnetic nitrogen.

In general, ceramics are clay making, collecting clay for ceramics, forming a shape according to the use of ceramics, drying drying moisture, and roasting at around 800 ° C. It is completed by biscuit firing, glazing of glazing on the surface of ceramics, and glaze firing in the temperature range of 1100 to 1300 degrees.

Therefore, the ceramic material should have good viscosity at the time of molding, have high fire resistance to withstand high temperatures, have a low shrinkage rate to prevent cracking, and contain as little iron as possible. On the other hand, if a typical example of the components of the base material for ceramics actually used are shown in Table 1.

The inventors have recognized that tidal soil corresponds to sedimentary clay (secondary clay) deposited by transporting secondary clay, that is, clay (primary clay) produced by weathering and hydrothermal reaction of rocks. As a result of analyzing X-ray Fluorescene (XRF) qualitative and quantitative analysis that the basic ingredients of ceramics as a secondary clay are in very good condition, tidal soil is SiO ₂ , Al ₂ O which is essential for ceramics and glazing Since it contains ₃ , it became aware that its utility is high.

Subsequently, the results of analyzing one example of such tidal flat soil composition (tidal land-09) are shown in Table 1 below.

Therefore, as a result of focusing on the above analysis, the present inventors have developed a method for producing porcelain base by purifying the mud flat soil of the present invention. The manufacturing method of the porcelain base using the present inventors mud flat soil is briefly shown in the flow chart of FIG. Although the present invention is not limited thereto, the present invention will be described with reference to the following.

Hereinafter, the manufacturing method of the base material for ceramics is demonstrated in detail.

The present invention comprises the steps of collecting the raw material by rolling up the mud flat soil;

Washing and deflecting the collected raw materials;

Mixing and pulverizing the washed and defended raw materials;

Classifying and filtration and dehydrating the mixed and ground raw materials to obtain a cake;

It provides a method for producing porcelain porcelain using the mud flat soil comprising the step of aging the refined raw material.

First, the tidal flats are rolled up to collect soil from the tidal flats. At this time, the mud flat soil to be collected is preferably within 50 cm from the surface of the tidal flat. This is because the depth containing the ingredient closest to the components of the porcelain base, and collecting the mudflat soil of depth exceeding this is difficult to obtain the proper components, especially, because the topographical changes of the tidal flat may occur.

The collected tidal-flat soil contains 50 wt% or more of SiO ₂ and 10 wt% or more of Al ₂ O ₃ , and the remainder preferably contains 1 to 3 wt% of the alkali component.

The collected raw material is washed and defended. Water washing is to remove the salt groups contained in the raw material, Elutriation is to remove impurities by sufficiently stirring and dispersing the raw material in water.

After performing the above water washing and defoaming, in order to remove iron from the raw material, further deironing can be performed. When the iron is not removed, some of the metal oxides such as Fe ₂ O ₃ are contained in the substrate, and thus, after firing, color substrates expressing the inherent color of the metal oxide can be produced.

In addition, in the case of de-carburization, the method of de-carburization is changed according to the grinding process. When performing a dry grinding process, permanent magnets are used, and when wet grinding is performed, slipping is performed at the same time as slipping through an electromagnet filter. At this time, the electromagnet filter and the electromagnetizer are used as the electromagnet filter.

The washed and defended raw materials or additionally deferred raw materials are mixed and ground. The mixing is to obtain a homogeneous mixing and stirring suspension, such as emulsions, slips, glazes in the refining process, grinding is to increase the plasticity and specific surface area to make the raw material to the size of the required use. The mixing and pulverization may be mixed by varying the component ratio of the raw material. Mixing by changing the composition ratio as described above can be obtained for the porcelain possession that can give a variety of colors during the manufacture of ceramics.

After the mixing and pulverization, screening and filtration dehydration are performed. The classification is carried out using a sieving, sedimentation separation, mechanical wet classification, liquid cyclone and table beneficiation. The filtration dehydration is performed using a manure filter, a clean filter, a cake filter, a pressure filter, and the like.

The classification and the filtration dehydration are performed to obtain a cake. The cake means a lump of soil containing moisture.

Train the cake. The refining is to ensure uniformity of water and bubbles for the purpose of mixing highly viscous materials, and it is preferable to use a kneader.

Aging is carried out after the above cultivation. This is for the uniformity of moisture and air bubbles in the porcelain holding by packaging for a certain period of time after packaging to prevent the moisture of the refined soil to dry. It is also intended to enhance plasticity due to the propagation of microorganisms in ceramics.

Hereinafter, a manufacturing method of the glaze for ceramics is briefly shown in FIG. 2. The raw material subjected to water washing and defoaming or the raw material de-added thereto may be mixed and ground, classified and filtered, and then mixed with water to prepare a glaze for ceramics. At this time, the mixing ratio of each component will vary depending on the desired state of the glaze.

Looking at the composition range of one example of glaze for ceramics produced by the method of the present invention is shown in Table 3.
