Description

[0001] The present invention relates to a salt farm and construction method,

The present invention relates to a tin salt application method and a salt salt produced therefrom, and more particularly, to a salt tin salt having excellent levelness and flatness using a novel gypsum toughening agent. .

Salt is not only essential for human health maintenance, but also is an indispensable seasoning for flavoring foods, and is used in a variety of ways, such as food storage and raw materials for the chemical industry.

Salt can be categorized into sun salt, rock salt, and processed salt depending on its source, and the salt is a thick, translucent hexagonal crystal made of untreated salt made by evaporating harmful substances together with moisture by wind and sunlight .

On the other hand, purified salt is a crystal of sodium chloride (NaCl) obtained by electrolyzing seawater to remove impurities and heavy metals from ionized membrane.

In Korea, sun salinity is not deep and is produced mainly in the west coast and southern coast where the tidal flats are large, and it is also produced in the Indian Ocean, the Mediterranean coast, the US, and Australia. Because it is rich in minerals and water such as calcium, magnesium, zinc, potassium, iron, etc., it is good for pickling of vegetables and fish. It is mainly used for making kimchi and making soy sauce and soybean paste. It is rich in minerals. It is said to be beneficial.

It is composed of reservoir, evaporation paper (first evaporation paper, second evaporation paper), and crystal paper, and it opens the water gate at high tide and makes concentrated salt water from the evaporation paper and sends it to the crystal paper to get salt crystals. In addition to reservoirs, evaporation sites, and deciduous grounds, the solar salt erosion additionally includes function tanks, salt depots, waterways, and working roads. Most of these reservoirs, evaporation ponds, function tanks, salt depots, waterways, and work roads are exposed to the tidal flats, and are used to cover the tidal flats such as thermal insulation covers, building materials, plywood, It can cause environmental pollution. In addition, the decision paper includes the following items: rust, heat cover debris, sand grains, pests, plant-derived foreign matter from infrastructure for compaction, insoluble matter from coastal tidal flats and tidal flats, In order to prevent such foreign matter from being mixed with the seawater or salt collected for the purpose of compaction, a floor covering material such as a rubber plate, a plastic plate, a tile or a pottery is coated on the surface of the ground, (Patent Document 1). In order to maintain the flatness of the salt plate, a plywood is laid and a rubber plate, a plastic plate and the like are laid down and used.

The seawater supplied to the upper part of the bottom closing member of the tile is evaporated by the solar heat and the wind and the salt is precipitated, and the upper surface of the bottom closing member is scraped off by using a rubber ladle . At this time, the flatness of the bottom finishing member is required to be smooth so that the precipitation of the salt can be smoothly performed, and the friction between the bottom finishing member and the bottom finishing member can be minimized.

Tile and Onggi have excellent flatness, but are expensive, they are easily broken due to low impact resistance and abrasion resistance, and it takes considerable time and expense to replace broken tiles. More than 90% It is the present situation that the main plate is mainly used.

However, floor finishing materials such as plastic flooring can cause environmental pollution through the use of synthetic resin adhesive during construction and can prevent the mites from communicating with the outside air, resulting in the death of life forms in mites and decay of mites. Therefore, generation of gas may bulge the base plate, which may adversely affect the flame-spreading operation. In addition, since periodic replacement work is required for maintenance, there is a problem that not only the cost is high but also a large amount of waste is generated.

Patent Document 2 discloses a flat plate which can maintain the flatness evenly throughout the flatness after being rolled and stored in the form of a roll, and can maintain the flatness of the upper surface while compensating for uneven bending of the bottom. And a manufacturing method thereof is disclosed.

Patent Document 3 discloses a salt batting plate capable of producing a salt of sun salt superior to a conventional PVC salt batting plate and also capable of preventing a harmful problem from occurring by not discharging harmful phthalate compounds to the human body and a manufacturing method thereof.

However, the torsion using the plastic sheet disclosed in the above patent document still has the disadvantages of the torsion sheet using the plastic sheet, which is still a problem.

In order to solve these problems, the present applicant has previously filed a patent application 10-2011-0112723 and 10-2011-0112728. In this prior art, there is a method in which a powdery material is used and a liquid phase is sprayed to solidify It is true that there was a difficulty in forming the horizontal and the flatness.

In addition, in the tulle welding by the above-mentioned prior application, the hardness of the surface of the salt plate was not satisfactory, and there was also a problem in that the tulle welding operation was not smooth.

Accordingly, the present inventors have found that there is no fear that waste will be generated without blocking communication with the outside air of mud, there is no fear of environmental pollution by using environment-friendly materials, periodic replacement work is not required for maintenance, The present inventors have developed a method for producing a new salt-applied salt plate which is excellent in flatness and has a high hardness on the surface of the salt plate and thus can be more easily worked.

The present invention also provides a method for constructing a useful salt plate having a workability, a productivity, and an economical efficiency since it is possible to control the viscosity required for working conditions by mulling a dull solidification.

Therefore, an object of the present invention is to provide an excellent torsion-inducing method and a torsion constructed according to the method.

In order to accomplish the above object, the present invention provides a method for torsionally dissolving a composition comprising a solid phase solidifying agent selected from the group consisting of blast furnace slag fine powder, fly ash, aluminum ash, volcanic ash, providing a first and _{second, M 2 O˙SiO 2 ˙Al 2 O} 3 ˙H 2 O (M = K, Na, or Ca), for the water and the liquid sodium silicate to Na ₂ O in the liquid sodium silicate, 10 to 20 By weight of concentrated sulfuric acid to form a sodium silicate salt and adding 20-30 wt% of the total weight of water to dissolve the sodium silicate salt and further adding a salt, oxide or hydroxide containing an alkaline earth metal Preparing a second agent containing an inorganic binder using liquid sodium silicate and mixing the second liquid phase and the mint to form a mortar of mortar type and then adding and mixing the first agent, ; A piercing step of piercing the bottom floor of the salt plate to be constructed; A pouring step in which the mixture is poured into the perforated layer to form a salt plate; A solidification step in which the formed salt plate is allowed to stand for 4 hours or more to solidify; A coating step of applying a coating agent to the surface of the dried salt plate; And the like.

Further, another feature of the present invention provides a torsion constructed according to the present invention.

Another aspect of the present invention provides the salt of the present invention prepared in the torsion method.

Hereinafter, the present invention will be described in more detail.

All technical terms used in the present invention are used in the sense that they are generally understood by those of ordinary skill in the relevant field of the present invention unless otherwise defined. In addition, preferred methods or samples are described in this specification, but similar or equivalent ones are also included in the scope of the present invention. The contents of all publications described herein as prior art are incorporated herein by reference in their entirety.

The inventors of the present invention have conducted studies to solve the problems of conventional tile, ongyo, and plastic top plate used as a bottom closing member in the production of a salt plate of a conventional salt, And the method of solidifying it by an environmentally friendly method. In addition, it has been realized that an inorganic material, which has never been used to make a salt plate by solidifying a conventional salt deposit, is applied as a red solidifying agent and the salt deposit of the salt is solidified by an environmentally friendly method. When a salt plating of a salt is solidified by an environmentally friendly method, a salt plating can be produced in an environmentally friendly and economical manner while maintaining the advantage obtained from a conventional method of preparing a salt plating of a salt by spreading a tile, a pottery, and a plastic plating.

Accordingly, in one aspect of the present invention,

A first agent comprising a solid phase solidifying agent selected from the group consisting of blast furnace slag powder, fly ash, aluminum ash, volcanic ash, and a combination thereof, is provided and M ₂ O ₂ SiO ₂ ˙Al ₂ O ₃ ˙H ₂ O (M = K, Na, or Ca), water and liquid sodium silicate are reacted with 10-20% by weight of concentrated sulfuric acid relative to Na ₂ O in liquid sodium silicate to form sodium silicate A second agent comprising an inorganic binder using sodium silicate soda prepared by adding 20-30 wt% of the total weight of water to dissolve the sodium silicate salt and further adding a salt, oxide or hydroxide containing an alkaline earth metal, Mixing the second liquid phase and the mint to form a mortar-like mallet, and then injecting and mixing the first agent;

A piercing step of piercing the bottom floor of the salt plate to be constructed;

A pouring step in which the mixture is poured into the perforated layer to form a salt plate;

A solidification step in which the formed salt plate is allowed to stand for 4 hours or more to solidify;

A coating step of applying a coating agent to the surface of the dried salt plate; The method comprising the steps of:

The "mollusks" described herein are sediments of more than 70% clay-sized particles, meaning mud that is present in the tidal-flat of the sea.

In order to prepare the mixture, a mixture of the mud and the second liquid phase collected from the tidal flats is mixed to form a mortar-like mull mortar, and the first agent is added thereto and mixed to prepare a mixture. 1 mixture is preferably 100: 20 to 30.

Herein, the natural fiber layer may be further mixed with the mullite. The natural fiber layer may be mixed with the mullite to have a volume ratio of 5 to 10% or less. The natural fiber layer means that the natural fiber is finely cut to a size of 2 to 10 mm in length and the natural fiber layer is preferably a cut hemisphere as shown in FIG. By further containing the natural fiber layer, it is possible to prevent cracks from being formed in the salt-bearing plate to be completed later.

In the piercing step, a pore is formed by piercing the piercing plate by a piercing roll to form a pore. The pore is formed into a shape having a diameter of 5 to 10 mm at a density of 1 to 2 pore / cm 2, The above mixture is poured into a salt plate and subjected to a flat work.

The method may further include the step of forming a mat layer by laying a natural fiber mat on the pit plate before pouring the mixture.

The mat layer is in the form of a net, and serves to further increase the tensile strength of the mats that are solidified according to the method of the present invention.

The natural fiber mat preferably has a pore size of 0.3-1 cm ^{2 and} has a pile shape to be solidified and a lower layer for communication between the pile and the lower layer. The natural fiber mat may include a matte as shown in Fig. 2, , A natural nonwoven fabric, a cotton mat, or the like can be used.

Preferably, the natural fiber mat is installed on the bottom surface of the mixture, preferably about 0.5-1 cm from the bottom surface of the salt diffusion plate, It is preferable to fix it.

When the mat layer is placed about 0.5-1 cm above the base of the mixture, the mortar-type mixture can penetrate through the pores of the mat-like mat layer to form a hard solid layer across the mat layer, The mat layer is more firmly fixed and the densified layer can be stably formed.

According to the present invention, the bituminous mortar, the bituminous coal, and the bituminous coal may be additionally formed on the mixture.

By further forming the bituminous coal layer, a black layer containing bituminous coal can be formed on the surface during the torsion application. When a black coal tar layer is included, it is particularly preferable to apply a salt evaporation site of a torsion column and a salt plate of a crystal ground. This is because if the distillation sites of the tidal plate and the surface of the crystal substrate are black, the evaporation of the seawater and the increase of the temperature of the concentrated brine are promoted by promoting the water evaporation by efficiently absorbing the radiant heat of the sun in the crystal paper, This is because the process of obtaining crystals can proceed more efficiently.

The content of bituminous coal in the mixture of the first agent, the bituminous coal and the mildite is not particularly limited, but it is preferable that the weight ratio of the bituminous coal to the mixture by mixing the first agent and the mildite is 70 ~ 80: 20 to 30, and the bituminous coal layer is formed by casting to a thickness of about 0.5 to 1 cm at the upper side of the mixture.

If the ratio of the bituminous coal exceeds the above range, the content of the solidifying agent may be insufficient and the solidification may not sufficiently occur, and it may be uneconomical. If the amount of the bituminous coal is less than the above range, You will not be able to.

Further, the bituminous coal layer can provide a functional salt plate that, when mixed with powders such as functional materials (elvan, pozzolan, clay, charcoal) and the like, is mixed with the bituminous material to provide a specific component according to the added substance.

The first agent used in the method of the present invention is a powder catalyst and the second agent should be separated into separate containers in the form of solidified mixed water and the first agent and the second agent should be used together And can function as a solidifying agent.

The blast furnace slag powder is a slag produced when pig iron is made from iron ore in a blast furnace, and impurities other than iron are collected, and it is known that 500 to 1,000 kg per 1 ton of pig iron is produced.

The fly ash refers to fly ash collected from a flue gas of a boiler that burns pulverized coal with a dust collector. The spherical particle size is similar to that of cement, and alumina and silica are the main components and are known to be used as an admixture of concrete .

The aluminum ash is a substance generated in an aluminum smelter.

The solid-state solidifying agent can be obtained from steel mills, power plants, aluminum smelters, etc., and is commercially available at present (Goroslagel SC-h) It is known not to have.

The component M ₂ O.SiO ₂ ˙Al ₂ O ₃ ˙H ₂ O (M = K, Na, or Ca) contained in the second agent is a geopolymer binder which is prepared by the method described in Korean Patent Application No. 2011-52939 And may be commercially available (Young Il Hwasung sc-201, ECO-100).

The gypsum solidifying agent is prepared by mixing a liquid second agent thoroughly with mullite to form a mull mortar which is in the form of a mortar, mixing the first mullite powder with the first agent, and allowing the first and second agents to react, In this case, the mats are solidified together and the mats are solidified as a result. When the first mats are added to the mallet and mixed for about 4 hours to 2 days, the mats can be solidified.

In order to solidify the mullite with the gypsum hardener, firstly the second agent is added in a range of 50 to 70% by weight of the mullite to be solidified and sufficiently mixed to form a mortar-like mullite, By weight and 20 to 50% by weight of the mallow mortar.

The above-mentioned torsion-type construction method can be used for constructing a torsion such as a reservoir, evaporation paper, and crystal paper. In addition, in any torsion-proof infrastructure including a functional tank, a salt warehouse, a waterway, Lt; / RTI > Particularly, it can be usefully used for the construction of a salt plate of a crystal paper.

FIG. 3 is a flow chart showing steps of a method of applying a salt of the present invention, and FIGS. 4 to 8 are schematic diagrams of a step of a method of implementing a method of applying a salt of the present invention.

a. Mixture (mild mortar) preparation step

In order to make fine mortal, a second liquid form is added to the mullite in a range of 50-70% of mullite weight, mixed into a container, and mixed with a stirrer to prepare a martal mortar.

The viscosity of mint mortar is added by adding or subtracting the second agent so that workability is easy. Here, the natural fiber layer (the cut natural fiber ratio 5-10%, see FIG. 1) may be mixed and mixed together when the second agent and the midge are mixed.

When the second mortar is prepared by mixing the second part 1: 0.8-1.5% as the first part and the second part by weight, the solidified mixture is solidified as a mixture (2).

b. Step

It is preferable to first remove foreign matter and contaminants from the surface of the tidal flats and planarize the surface of the tidal flats prior to developing the mixture (2) in the tidal flats (1) in the tidal flats in a certain area where the tidal flats are to be formed.

In order to planarize the tidal flats, a process of flattening the tidal flats according to any method known in the art such as seawater input, horizontal operation, and drying is performed can do.

FIG. 3 shows a schematic view of a tidal flat section where the pierced hole 4 is formed, in which the pier layer 1 is flattened.

This type of mortar is to be used when mallet mortar is put into the mallet.

The perforation can be made with any size of density while forming voids of any size that allow the mixture to be well injected into the mud. Preferably, the pores having a diameter of 5 to 10 mm can be formed at a density of 1 to 2 pores / cm ² . The perforation work may be performed in any manner, or may be performed using any perforated lawn machine known in the art.

c. Step of casting

The mixture 2 is poured into the mud layer 1 punched in the piercing step and the mixture 2 is in the form of a mortar so that it can smoothly flow into the hole 4 from the puddle layer where the puddle is formed and can be fixed .

Here, before placing the mixture 2, a natural fiber mat is laid on the basal plane of the mud layer 1, which is selectively punched, by about 0.5-1 cm, and fixed by a fixing means such as a fixing pin, The fiber mat layer 2-1 can be formed.

5, the mixture 2 flows into the mattress hole 4 through the matte layer 2-1 and is introduced into the mixture 2 as a whole And is in a form including the mat layer 2-1 so that the mat layer 2-1 is solidified in a state including the mat layer 2-1.

The poured mixture 2 is subjected to a purging operation. In this specification, the term " planarization " refers to an operation of leveling the surface horizontally. Finishers can be used for the planarization. In the present specification, " finishing " refers to a machine that automatically performs horizontal finishing work, and various types of finishing agents are commercially available. Those skilled in the art can appropriately select which finishing agent to use for flattening the tidal flat. You can use the Daewoo machine's secret machine (horizontal work vibrator).

After the flattening process is performed, the surface of the mixture 2 is flattened and then solidified. As shown in FIG. 6, when the surface of the mixture 2 is flattened, It is possible to selectively form the bituminous coal layer 3 including the first agent and the bituminous coal.

In order to form the bituminous coal layer, it is necessary to prepare a mixture of bittern mortar, the first bituminous material and bituminous coal. To manufacture the mixture, a separate bituminous material, a first bituminous material and bituminous coal (functional material) And the mixture for forming the bituminous coal layer (functional material layer) thus formed is uniformly placed on the mixture (2).

Then, the flattening with a finishing agent is carried out to complete the bituminous coal layer 3. The bituminous coal layer is preferably formed to a thickness of about 0.5 to 1 cm.

d. Solidification stage

Then, the flattened tidal flats are left to solidify the mud. It is preferable that the mud is entirely covered with vinyl before solidification. This is to prevent cracks from being generated due to rapid water evaporation during solidification.

If left for about 4 hours to 1-2 days, sufficient solidification may be achieved, and the solidification time may vary depending on the external temperature and humidity.

After sufficient solidification, it is desirable to carry out the following surface polishing work for the production of the crystalline substrate in a salt solution.

First, the surface of the sufficiently solidified salt plate is ground with a grinder (e.g., Daewoo Machinery, DW-420), and then the surface reinforcement is sprayed to further strengthen the surface.

As the surface strengthening agent, it is possible to use a high-concentration salt water or a water-resistant liquid sodium silicate in which a part of Si moieties of a network structure made of SiO ₄ is replaced by one or more additional network structural elements selected from the group consisting of boron, phosphorus and aluminum have.

The water-resistant liquid sodium silicate may be prepared according to the method disclosed in Korean Patent Registration No. 0495299, and preferably a commercially available inorganic binder (NS-TOP ^TM , manufactured by Young Il Chemical Co., Ltd.) may be used.

After the application of the surface strengthening agent, the surface is ground and polished using a grinder (e.g., Daewoo Machinery, DW-420). Thus, once the surface grinding operation is finished, it is properly cleaned with fresh water or seawater and dried.

e. Coating step

After the abrasion is performed as described above, the surface of the salt plate is coated with a coating agent, which is environmentally friendly, has a salt resistance, breathability, abrasion resistance and the like and is highly resistant to ultraviolet rays, and is used with a brush, a painting roller or a spray gun To form a coating layer (5).

Where the coating can be a commonly used surface coating (e.g. SG Industries EXCOAT ^TM ).

After the coating is completed, sufficient curing can be achieved by leaving it for about 4 hours to 1-2 days, and the curing time may vary depending on the external temperature and humidity.

After the coating is sufficiently cured, the surface of the salt plate is polished and polished by a grinder. When finished, the surface of the salt plate is cleaned with fresh water or seawater twice or three times to clean unreacted materials and contaminants, You can complete the substrate.

In another aspect, the present invention provides a torsion constructed according to the method of the present invention.

The tidal field is not limited to a tidal field in which salt is directly produced, such as a salt reservoir, a evaporation field, and a deciduous ground, as well as at least one of a function tank, a salt warehouse, , And particularly preferred is a tribological plate in which a tribological plate of torsion is constructed according to the present invention.

The salt deposit according to the present invention solidifies the mudflats of the tidal flats and can be a more hygienic working environment. Particularly, when the salt of the salt is crystallized in the crystal paper, as in the case of the conventional plastic plate, There is no worry, so you can produce safer sun salt. In addition, while the salt plate manufactured by the conventional plastic plate takes a lot of time and cost for maintenance of the plate, the salt plate according to the present invention does not need to do so, and the salt can be produced economically.
