The present invention relates to artificial soil, and more particularly, to an antimicrobial artificial soil and a method of manufacturing the same.

In general, soil or gardening clay is used for ornamental flower pots, rooftops, and simple flower beds in homes. These horticultural soils can be largely divided into mixed soils and special soils. Mixed soils include pitlite mixed soils and bark mixed soils. Special soils include rock wool, vermiculite, perlite, sand, and peat moss. (peat moss), conception, flounder, bark, rice husk, hultan or mixtures thereof.

For example, mixed soil is also referred to as culture soil, and refers to soil mixed in such a manner that the soil has good physical properties, breathability, water retention, and maintenance ability, and contains nutrients necessary for plant growth. In particular, the pitlite mixed soil is a horticultural soil made by mixing pit and vermiculite or pearlite, and is light and well sterilized, and its chemical and physical properties are suitable for plant growth. Bark mixed soil is a mixed soil made by mixing bark, sand, and pits of fir, pine, and pit at 3: 2: 1. In addition, horticultural clay is used by mixing perlite and vermiculite on the basis of ripe compost or foliar soil.

As such, despite the presence of various mixed soils, special soils, and artificial soils, the pots and flower beds had to be separately provided with drainage holes at the bottom for draining. If the drainage hole is clogged or not provided, there is a problem that the roots rot because the water does not fall out.

In addition, when a flower bed is formed on the roof of the soil, the weight of the soil imposes a burden on the building or the size of the flower bed is limited.

Other objects, specific advantages and novel features of the invention will become more apparent from the following detailed description and the preferred embodiments described in conjunction with the accompanying drawings.

The invention will now be described in detail with reference to the accompanying drawings, in which preferred embodiments are shown.

(Production method of the first embodiment)

1 is a flow chart showing a method for producing antimicrobial artificial soil according to the first embodiment of the present invention. As shown in FIG. 1, first, 1 part by weight of borax, 1 part by weight of boric acid, and 1 part by weight of soda are mixed with 24 parts by weight of kaolin (S10). Here, borax, boric acid, and soda serve as a melting agent for melting, specifically, 22 kg of borax, 20 Kg of boric acid, and 20 Kg of soda are blended with respect to 480 Kg of a large amount of clay. Borax, boric acid, and soda, as a unit, serve as a melter, and a melter is a substance that facilitates melting of minerals. If the melt agent enters less than the above-described range, the functional aspect of facilitating melting is weakened, which increases the melting temperature and time. In addition, when the melting agent is more than the above-described range, the melting occurs easily, but the function due to the aging is reduced, so that the antimicrobial and far-infrared radiation is significantly reduced.

Then, the blended formulation is heated to a glass transition temperature (glass transition temperature) in the furnace (S12). At this time, the glass transition temperature is about 1,400 ° C., and the glass transition temperature is heated to about 13 hours. At this glass transition temperature, the viscosity of the formulation is about 1012.5 Pa.s and the state represents a sticky flow such as crude syrup or starch syrup.

Then, the heated compound is poured into a pair of rollers to form a plate while passing through and naturally cooled (S14). At this time, the spacing between the rollers may vary depending on the thickness of the desired plate shape. Such natural cooling (or slow cooling) causes hexagonal columnar crystals to grow inside the compound.

Next, the naturally cooled and completely hardened plate-like article is ground into glass crystalline particles having a diameter of 3 mm or less (S16). For this milling, conventionally known shredders can be used.

Then, deburring the crushed particles to blunt the surface of the particles (S18). Since the particles crushed through the crusher are glass crystalline, they have a sharp glass blade or sharp awl on the surface. To blunt these surfaces, the particles are deburred to make the surface soft and dull. This is to prevent planting in flowerpots, injury to hands or tearing of envelopes during distribution. It also protects plant roots from sharp surface conditions. High speed centrifugal choppers can be used for this. Deburred particles may also be used by spraying on the pot (S22).

Then, 3 parts by weight of deburred particles are mixed with respect to 97 parts by weight of soil (S20), and used in a pot (S24). When the deburred particles are smaller than 1 part by weight, the antimicrobial and far infrared ray releasing effects are insufficient, and when the deburred particles are larger than 10 parts by weight, malnutrition in the pollen or smooth root growth may be prevented.

(Manufacturing Method of Second Embodiment)

2 is a flowchart illustrating a method of manufacturing antimicrobial artificial soil according to a second embodiment of the present invention. As shown in Fig. 2, steps S10 to S18 are the same as or similar to the first embodiment. Therefore, such description will be omitted.

The particles (S16) or deburred particles (S18) pulverized to a diameter of 3 mm or less are foamed while being melted in an electric furnace (S30). To this end, it is melted for about 3 hours at a temperature of about 700 ℃, the pressure of about 12 bar is supplied into the electric furnace for foaming. To this end, the expansion ratio is about 5 times. If the air pressure is too high or the foaming ratio is too high, the voids may increase as the foaming volume increases, but if excessive, the voids tend to be filled with soil, so that they cannot be used as volcanic stones or turbulent stones (stones laid on a fire). do.

On the other hand, if the foaming pressure is too low or the foaming ratio is low, the voids are too small to replace the turbulent or volcanic stones, there is a disadvantage that the weight increases.

Then, cut after the natural cooling so that the diameter ranges from 5 mm to 50 mm (S32). It can be cut to a larger extent depending on the size or need of the widely used turbulent or volcanic stone.

Then, mixed 1 to 10 parts by weight of artificial soil foamed with respect to 90 parts by weight of soil or soil (S34). When the foamed artificial soil is less than 1 part by weight, the effect is insignificant, and above 10 parts by weight, it inhibits root growth and lowers economic efficiency. Since the foamed artificial soil has many micropores inside, sufficient oxygen supply is achieved even if it does not contain more than 10 parts by weight.
