Abstract

PURPOSE: Provided are yellow earth and charcoal construction products(board, brick and air filter) using sodium silicate, an aqueous ceramic binder, instead of conventional binders. The resultant products produced by drying(<=130deg.C) and forming has air-permeability, dampproofing, far infrared emission and good strength. CONSTITUTION: The yellow earth and charcoal products are produced by the following steps; grinding yellow and charcoal, and screening; adding an aqueous ceramic binder, sodium silicate, which is ground and screened; drying at less than 130deg.C; pressing under the high and the low pressure for high strength products such as bricks, blocks, tiles, etc. and low strength products such as industrial filters, respectively; drying at less than 130deg.C.

Description

High strength molding of ocher and charcoal products using aqueous ceramic binders {Ceramic Bonding Mechanics of yellow clay and Carbon black members.}

The present invention is an aqueous ceramic binder whose main theme is sodium silicate based on ocher and charcoal materials (boards, bricks and industrial air filter), and meets the unique function of ocher and char at low temperature below 130 degrees Celsius and meets the construction materials standard. It relates to a method of manufacturing.

Conventional building materials have solidified organic binders and cements as main binders, but the physical properties of loess have resulted in poor compressive and tensile strengths or impaired the intrinsic function of the main materials. It is an unsatisfactory technology for building materials, although it fulfills the inherent function of ocher, but it has low strength and high shrinkage rate, so it is cracked and weak in water.

Loess belonging to clays with an average particle size of 0.002 mm or less containing a colloid with a particle size of 0.1 to 0.001 micron, and having a pore area of 30 to 90% between the particles, Obtaining a suitable product did not meet the standard by the existing low-temperature manufacturing method, but the present invention is solid by applying ceramic coating on the outside of the ocher subunit particle group, which is pulverized and screened for product use, using an aqueous ceramic binder based on sodium silicate. When the film is formed, the subunit particle group treated with the film is mixed with the ceramic binder in a predetermined ratio, press-molded and desorbed by a hydraulic molding machine, and dried at a low temperature of 130 degrees Celsius or less. Fine pores in the process of evaporation of moisture in the product Is formed has an air-permeable.

The indoor humidity control function of the ocher is made through pores, and the moisture absorption and release is made in a group of small particles that are firmly coated to prevent cracking of the product, thereby making use of the characteristics of the ocher itself and producing products that meet the construction material standard. It is to provide a manufacturing method.

Charcoal is also porous. Charcoal varies from material to material, but typically has a surface area of 300 square meters per gram. To make architectural and industrial materials (bricks, boards, and wheels) out of this amazing hole of charcoal, you need to make the most of the charcoal's unique features. Depending on the product, the outside of the small particle group, which is crushed and screened, is firmly coated with a ceramic binder having a large number of vents. It is to provide a manufacturing method for producing a product conforming to the standard.

Looking at the manufacturing method of the present invention in detail as follows.

That is, the manufacturing method of the present invention is composed of the first and second processes, as illustrated in Figure 5 in the first step in the grinding process of the main material ocher or charcoal in accordance with the product characteristics, and the addition of the functional screen Mixing and mixing the stirred and mixed main body and the member with the aqueous ceramic binder, which is the main body of sodium silicate, by mixing and pulverizing at a predetermined ratio, and drying to 130 degrees C or less, a ceramic-coated subunit particle group can be obtained as illustrated in FIG. .

In the secondary process, a predetermined film particle group and a predetermined ceramic binder are mixed and agitated according to the product specification, and molded and desorbed at high pressure and low pressure according to the product specifications, and dried to 130 degrees Celsius or less. Likewise, high density high strength products, ie bricks, appendixes, tiles, boards, etc. can be obtained, and in the case of low pressure molding, low density high strength products, ie, air flow rate selection and thickness dimension selection selection, as illustrated in FIG. 4. Produce industrial wheel rudders.

The present invention is a manufacturing method of molding the mineral of the porous microparticles with a silicate-based ceramic binder

First, it does not destroy the structure of the material itself, thereby maintaining the functionality as it is.

Second, it is economical and competitive in other products because it is processed at low price with aqueous ceramic binder and low temperature.
