Abstract
Description
The present invention relates to a zeolite for increasing bibbing force for promoting growth and promoting rooting in soil used in grass composition, and more particularly, to a method for producing zeolite having higher physical stability than natural zeolite, The present invention relates to a method for producing a zeolite which meets the physical and chemical performance required for the soil used in the composition and which moreover fulfills the physical demands required for natural grass composition in supplying zeolites rich in bouncy and moisture, to be.
In building natural grass, the physical properties required for the soil should be permeability, porosity, bending strength, and moisture. Especially, when making lawns such as golf course or playground, Weathering stability.
Especially, in the lawn care, frequent watering and fertilization of the pods are required, which requires resistance.
As described above, in order to meet the demand, it is general to complete the soil in the form of a gravel layer, an intermediate layer and a soil layer by separating and sorting gravel, silica sand, crushed stone, .
The materials such as gravel and silica used in the grass composition have a relatively high toughness but relatively low moisture and brittleness.
Therefore, there has been a difficulty in frequent irrigation and fertilization due to materials such as gravel and silica which have low water holding capacity and low bending strength for the maintenance and maintenance of lawn. Furthermore, due to frequent irrigation, the fertilizer component is easily leached from the surface, resulting in difficulty of lawn management and eutrophication of drainage.
In order to solve such difficulties, it has been known as a solution to add natural zeolite having high moisture resistance and brittleness to gravel and silica used for the soil used in the lawn composition.
However, when natural zeolite is added to the soil, it must have weathering stability due to its chemical stability, and it must have compressive strength and abrasion strength to support the diaphragm load due to its physical stability.
In 2004, the American Golf Association (USGA) allowed zeolite as a porous inorganic improving agent for golf course lawn formation. However, materials with a physical test result of less than 40 as a result of LA Ablation Test (ASTM C-131) It is recommended to use in soil. As natural zeolite, micropores have been formed on the zeolite structure in order to satisfy such conditions, and it has been particularly difficult to attain wear strength.
Thus, Patent Application No. 10-2011-0129794 discloses a method for producing a zeolite in which a natural zeolite is impregnated with a boron compound solution, dried and fired to form vitreous on the surface thereof.
However, the use of the boron compound alone in a product produced by such a method may cause excessive boron damage due to boron overdissolution in the soil, and there is a limit to increase the physical and chemical performance simply by forming a thin glass on the surface of the zeolite.
Disclosure of Invention Technical Problem [10] Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a zeolite- The present invention provides a zeolite having a higher abrasion strength as a physical property as a soil composition in a grass composition. Another object of the present invention is to provide a method for preparing a soil composition in a grass composition.
In one embodiment, the natural zeolite is pulverized, the granular particles are separated and sorted to a predetermined size, and the granular zeolite selected is dried, impregnated with a solution of potassium carbonate (K2CO3) dissolved in purified water in a predetermined amount and impregnated with natural zeolite The solution is concentrated and the water is evaporated to allow the natural zeolite to be supported and coated with potassium, and then dried sufficiently and calcined at a predetermined temperature to increase the abrasion strength of the natural zeolite. .
Accordingly, the present invention provides a process for producing zeolite, comprising the steps of: (a) screening and separating natural zeolite by sieving each particle, (b) firstly drying the granular zeolite sorted and separated, (d) impregnating the dried zeolite with a solution of potassium carbonate (K2CO3) A step of secondarily drying the zeolite by evaporating only water in the solution impregnated with zeolite, a step of calcining the second dried zeolite, and a step of spontaneously cooling the calcined zeolite to obtain a zeolite And a manufacturing method thereof.
Also, the present invention is a method for producing zeolite as a soil composition for lawn composition, wherein the granular zeolite has a size of 0.3 mm to 20 mm.
The present invention is a method for producing zeolite as a soil composition for lawn composition, characterized in that the solution is 5 to 15% by weight of the purified water in the solution containing potassium carbonate.
Also, the present invention is a method for producing zeolite as a soil composition for lawn composition, wherein the calcination temperature is 950 ° C to 1100 ° C in the step of calcining the secondary dried zeolite.
In the natural grass composition, the zeolite according to the present invention can provide a soil composition having a high abrasion strength while retaining its inherent physical properties such as brittleness and water retention, and having resistance to abrasion by man or machine.

FIG. 2 is a flow chart
Hereinafter, the configuration of the present invention will be described in detail as follows.
In order to explain the preferred embodiments of the present invention, the thicknesses of the lines and the sizes of the components shown in the attached drawings may be exaggerated or omitted for clarity and convenience of description, Terms to be given are terms defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator.
Fig. 1 is a photograph showing the wear test of potassium carbonate treated zeolite and untreated zeolite under the same condition, and Fig. 2 is a process flow chart of the present invention.
In the present invention, natural zeolite is pulverized, separated by a predetermined sieve, and natural zeolite selected and separated is sufficiently dried. At this time, the drying method is naturally dried or heated and dried at a temperature of less than 500 ° C.
The zeolite thus dried is impregnated with a solution in which 5 to 15% of potassium carbonate is dissolved in purified water by weight.
The amount of potassium carbonate is preferably 8 to 12% by weight based on the weight of the purified water.
At this time, the amount of the solution in which potassium carbonate is dissolved is about 80 to 150% of the weight of the dried zeolite. However, if the amount of the solution is small, it is difficult to uniformly carry and apply the potassium to the zeolite. If there is a large amount of solution, it is difficult to dry the zeolite by evaporating the water by concentration
Therefore, the solution in which potassium carbonate is dissolved is preferably 90 to 100% of the weight of the zeolite to be impregnated.
The zeolite carrying and coating the potassium carbonate is evaporated to a sufficient degree to be secondarily dried, then calcined, and then naturally cooled to complete the present invention.
At this time, the firing temperature should be set to be higher than the melting point of potassium carbonate, so that the abrasion strength and compressive strength of the zeolite can be set high. However, if the firing temperature is too high, the bending strength and moisture retention of the zeolite deteriorate.
Therefore, the firing temperature is suitably 950 to 1100 占 폚, and more preferably 980 to 1050 占 폚.
As a result, the zeolite obtained by the present invention having a relatively high abrasion strength can be supplied as a soil composition to the grass composition.

The solution was immersed in a solution of 15 g of potassium carbonate in 300 cc of purified water and allowed to stand at room temperature for about 12 hours. Then, the water was evaporated at normal pressure to 90 ° C to sufficiently dry the zeolite. The time was maintained, and it was naturally cooled after firing.
Example 3 .
Natural zeolite collected from Sangjeongri 59, Donghae-myeon, Pohang-city, Gyeongbuk Province, was crushed and separated into 6 mesh sieves, except for 6 meshes or more, except that 14 mesh sieved zeolite was removed from the granular zeolite at 980 ℃ for 2 hours After holding and firing, it was naturally cooled.
Comparative Example 1 .
200 g of the zeolite of Example 1 and 70 g of alumina ceramic balls having a diameter of 3 mm were charged together and sealed in a hard plastic polyester bottle having a diameter of about 7.5 cm and a height of about 14 cm to obtain a mixture of 200 g of the zeolite of Example 3, Were charged together in a rigid polyester plastic bottle of the same size as described above and then rotated under the same conditions at a rpm of 60 to 90 for about 98 hours to prepare a 14 mesh sieve having a weight of 14 mesh or less. Respectively.
