Description

How to apply radon blocker

[0001] The present invention relates to a method for applying a radon blocking agent.

[0002] Radon is an inert gas that is identified as one of the causes of lung cancer. It is created after uranium (238U) and thorium (232Th), which exist naturally in rocks and soil of the Earth's crust, undergo several stages of radioactive decay.

[0003] Radon can be released from the ground and enter indoor spaces through cracks in buildings, as well as through building materials. Because radon is an inert gas that does not chemically react at room temperature, capturing and eliminating it through chemical reactions is difficult. Furthermore, because radon particles are smaller than a few nanometers in size, filtering them out is also challenging.

[0004] Therefore, there is a need to develop a technology that can block radon generated from cracks in buildings and building materials from entering indoor spaces.

[0005] The present invention has been devised to solve the above-described needs, and relates to a method for applying a radon blocking agent capable of blocking radon generated from cracks in buildings, building materials, etc. from entering indoors.

[0006] In order to solve the above-described problem, the present invention may include the following configuration.

[0007] A method for applying a radon blocking agent according to the present invention may include a step of preparing a radon blocking agent; a step of spraying the radon blocking agent onto a spray area and applying the radon blocking agent onto the spray area; and a step of drying the radon blocking agent applied onto the spray area.

[0008] In the method for applying a radon blocking agent according to the present invention, the step of applying the radon blocking agent may include the step of spraying the radon blocking agent; and the step of spraying a confined gas into a confined area surrounding the outside of the spraying area.

[0009] In the method for applying a radon blocking agent according to the present invention, the radon blocking agent may include an elastic composite compound.

[0010] In the method for applying a radon blocking agent according to the present invention, the elastic composite compound may be a mixture of 55 to 65 parts by weight of vinylacetate-ethylene copolymer emulsion, 20 to 25 parts by weight of vinyl acetate monomer, 8 to 12 parts by weight of liquid stabilizer, 8 to 12 parts by weight of dihydrogen oxide, 28 parts by weight of an elastic waterproofing agent including 1 to 3 parts by weight of a preservative, 70 parts by weight of Remital, and 2 parts by weight of water.

[0011] In the method for applying a radon blocking agent according to the present invention, the radon blocking agent may include 63 parts by weight of a PVA (Poly Vinyl Alcohol) solution, 30 parts by weight of silicone, 2 parts by weight of SDS (Sodium Dodecycl Sulfate), and 5 parts by weight of nanofiller.

[0012] In the method for applying a radon blocking agent according to the present invention, the PVA solution may be a solution in which distilled water and PVA are mixed in a weight ratio of 8:2. The nanofiller may be zeolite or nanoclay.

[0013] According to the present invention, the following effects can be achieved.

[0014] The present invention can apply a radon blocking agent by spraying it, thereby improving the uniformity of the applied radon blocking agent. Accordingly, the present invention can uniformly impart a blocking effect that prevents radon from entering a room, thereby reducing the amount of radon entering the room.

[0017] Figure 3 is a schematic perspective view showing an enlarged view of the annular air injection member illustrated in Figure 2.

[0018] Figure 4 is a front view viewed in the direction “A” of Figure 2.

[0019] Figure 5 is a schematic side view showing a method for applying a radon blocker according to the present invention in which a restricted gas is injected into a restricted area and the radon blocker is injected only into the injection area.

[0020] Hereinafter, an embodiment of a method for applying a radon blocking agent according to the present invention will be described in detail with reference to the attached drawings.

[0021] Referring to FIGS. 1 to 5, the method for applying a radon blocking agent according to the present invention applies a radon blocking agent to an object, thereby enabling the radon blocking agent applied to the object to block radon generated from the object from entering the room. The object may be an interior wall surface made of a gap in a building, building materials, etc.

[0022] The method for applying a radon blocker according to the present invention can be performed using a spray gun. Before describing an example of the method for applying a radon blocker according to the present invention, the spray gun will be described in detail with reference to the attached drawings.

[0023] Referring to FIGS. 1 to 5, the spray gun may include a main body (100) and a restriction portion (200).

[0024] The above body (100) can form the overall appearance of the spray gun. A radon blocking agent injection nozzle (110) can be formed at the front end of the body (100). The radon blocking agent injection nozzle (110) can spray the radon blocking agent. The radon blocking agent injection nozzle (110) can spray the radon blocking agent. The radon blocking agent injected by the radon blocking agent injection nozzle (110) can be applied to the object. In this way, since the spray gun can apply the radon blocking agent to the object by spraying the radon blocking agent, the uniformity of the radon blocking agent applied to the object can be improved. Accordingly, the spray gun can uniformly apply a blocking force to the entire object to block radon from entering the room. Accordingly, the spray gun can reduce radon from entering the room. The radon blocking agent injection nozzle (110) can be formed at the center of the front end of the body (100). A radon blocking agent supply hose (120) can be connected to the lower part of the above main body (100).

[0025] The above-described restriction part (200) can inject a restriction gas. The restriction part (200) can inject the restriction gas into a restriction area surrounding the outer side of the injection area, thereby allowing the radon blocking agent sprayed by the radon blocking agent injection nozzle (110) to be applied only to the injection area. Accordingly, the spray gun can prevent the radon blocking agent from scattering and contaminating the surroundings. In addition, the spray gun is implemented so that the worker can easily apply the radon blocking agent only to the desired injection area, thereby contributing to improving the ease and accuracy of the work of applying the radon blocking agent. The restriction part (200) is provided so that the center is connected to the radon blocking agent injection nozzle (110) and circumferentially surrounds the radon blocking agent injection nozzle (110). In this case, a restricted gas supply hose (130) connected to a restricted gas supply source may be mounted via a bracket at the rear end of the main body (100) as a means for supplying restricted gas to the restricted section (200). Accordingly, the restricted gas supply hose (130) may be connected to the restricted section (200). The restricted gas may be compressed air.

[0026] The above-mentioned restriction (200) may include an annular tube (210), a nozzle connection member (220), an air outlet (230), and a hose connection member (240).

[0027] The annular tube (210) may have a diameter larger than the radon blocking agent injection nozzle (110). The annular tube (210) may be formed in an annular shape. The annular tube (210) may have a circular cross-sectional shape.

[0028] The above nozzle connecting member (220) can connect the annular tube (210) to the radon blocking agent injection nozzle (110). The nozzle connecting member (220) can include a nozzle coupling portion (221) and a plurality of ribs (222).

[0029] The nozzle coupling part (221) may be arranged coaxially with the annular tube (210). The nozzle coupling part (221) may be arranged at a predetermined distance from the annular tube (210). The nozzle coupling part (221) may be formed in an annular shape having an inner diameter that can be coupled to the circumference of the radon blocking agent injection nozzle (110).

[0030] The above ribs (222) are arranged radially to the nozzle coupling portion (221) so as to connect the nozzle coupling portion (221) to the annular tube (210).

[0031] The above air outlet (230) may be arranged along the circumferential direction on the annular tube (210) so as to be positioned in the opposite direction of the nozzle coupling portion (221). The restricted gas supplied to the annular tube (210) may be discharged through the air outlet (230).

[0032] The above hose connection part (240) may be provided on one side of the annular tube (210) so as to be in fluid communication with the interior of the annular tube (210). The hose connection part (240) may be connected to the restricted gas supply hose (130).

[0033] In this restriction (200), when the nozzle coupling portion (221) of the nozzle connecting member (220) is coupled to the radon blocking agent injection nozzle (110), the annular tube (210) can be arranged to circumferentially surround the radon blocking agent injection nozzle (110).

[0034] The above spray gun may include a cover body (300).

[0035] The cover body (300) may be formed into a cylindrical shape with one side open. The opposite side of the open side of the cover body (300) may be coupled to the circumference of the radon blocking agent injection nozzle (110). Accordingly, the cover body (300) may be arranged to surround the restriction portion (200), thereby blocking external leakage of the radon blocking agent and the restriction gas.

[0036] Using a spray gun like this, a method for applying a radon blocker according to the present invention can be performed. The method for applying a radon blocker according to the present invention can include the following steps.

[0037] First, a radon blocking agent is prepared (S10). This step (S10) can be accomplished by preparing a radon blocking agent to be applied to the target object. The step (S10) of preparing the radon blocking agent can be accomplished by connecting the radon blocking agent supply hose (120) to the main body (100). In this case, the restricting gas supply hose (130) can be connected to the restricting unit (200).

[0038] Next, a radon blocking agent is applied (S20). This step (S20) can be performed by spraying the radon blocking agent into the injection area and applying the radon blocking agent to the injection area. The injection area may correspond to a part of the object. Through the step (S20) of applying the radon blocking agent, the method for applying the radon blocking agent according to the present invention can apply the radon blocking agent to the object by spraying the radon blocking agent, and thus can improve the uniformity of the radon blocking agent applied to the object. Accordingly, the method for applying the radon blocking agent according to the present invention can apply the radon blocking agent to the object so that the blocking force for blocking radon from entering the room is uniformly applied to the entire object. Therefore, the method for applying the radon blocking agent according to the present invention can reduce radon from entering the room. The step (S20) of applying the radon blocking agent may be performed by the radon blocking agent injection nozzle (110) being positioned so as to face the injection area and spraying the radon blocking agent. The step (S20) of applying the radon blocking agent may be repeatedly performed while changing the injection area until the radon blocking agent is applied to all areas requiring application of the radon blocking agent.

[0039] Next, the radon blocker is dried (S30). This step (S20) can be accomplished by drying the radon blocker applied to the injection area. The step (S30) of drying the radon blocker can be performed by drying the radon blocker applied to the injection area at room temperature.

[0040] Here, the step of applying the radon blocking agent (S20) may include a step of spraying the radon blocking agent (S21) and a step of spraying the restricting gas (S22).

[0041] The step (S21) of spraying the radon blocker can be performed by spraying the radon blocker toward the spraying area. The step (S21) of spraying the radon blocker can be performed by spraying the radon blocker using the radon blocker spray nozzle (110).

[0042] The step of injecting the restricting gas (S22) may be performed by injecting the restricting gas into a restricted area surrounding the outside of the injection area. The restricting gas injected into the restricted area through the step of injecting the restricting gas (S22) may prevent the radon blocker injected through the step of injecting the radon blocker (S21) from flying outside the injection area. Accordingly, the method for applying a radon blocker according to the present invention may prevent the radon blocker from flying and contaminating the surroundings. In addition, the method for applying a radon blocker according to the present invention may be implemented so that a worker can easily apply the radon blocker only to a desired injection area, thereby contributing to improving the ease and accuracy of the work of applying the radon blocker. The step of injecting the restricting gas (S22) may form an air curtain in the restricted area by injecting the restricting gas into the restricted area. This air curtain may be formed to surround the injection area. That is, the injection area may be positioned inside the air curtain. The restricting gas may be compressed air.

[0043] The step of injecting the above-mentioned restricted gas (S22) and the step of injecting the radon blocker (S21) may be performed simultaneously. The step of injecting the restricted gas (S22) may start before the step of injecting the radon blocker (S21) and may end later than the step of injecting the radon blocker (S21). Accordingly, the method for applying a radon blocker according to the present invention may start injecting the radon blocker while the restricted gas is being injected, and may stop injecting the radon blocker first and then stop the injection of the restricted gas. Therefore, the method for applying a radon blocker according to the present invention may strengthen the prevention performance for preventing the scattering of the radon blocker, thereby strengthening the prevention power for preventing the surroundings from being contaminated by the radon blocker.

[0044] In the method for applying a radon blocking agent according to the present invention, the radon blocking agent may include an elastic composite compound. The elastic composite compound may be a mixture of vinylacetate-ethylene copolymer emulsion (VAE), vinyl acetate monomer, a liquid stabilizer (solvent naptha), dihydrogen oxide, an elastic waterproofing agent, Remital, and water. In this case, the elastic composite compound may be a mixture of 55 to 65 parts by weight of vinyl acetate-ethylene copolymer emulsion, 20 to 25 parts by weight of vinyl acetate monomer, 8 to 12 parts by weight of liquid stabilizer, 8 to 12 parts by weight of dihydrogen oxide, 28 parts by weight of an elastic waterproofing agent, 70 parts by weight of Remital, and 2 parts by weight of water. The elastic waterproofing agent may include 1 to 3 parts by weight of a preservative.

[0045] In the method for applying a radon blocker according to the present invention, the radon blocker may include a PVA (Poly Vinyl Alcohol) solution, silicone, SDS (Sodium Dodecycl Sulfate), and a nanofiller. In this case, the PVA solution may be a solution in which distilled water and PVA are mixed in a weight ratio of 8:2. The nanofiller may be zeolite or nanoclay. Meanwhile, the radon blocker may include 63 parts by weight of a PVA solution, 30 parts by weight of silicone, 2 parts by weight of SDS, and 5 parts by weight of a nanofiller.

[0046] The present invention described above is not limited to the above-described embodiments and the attached drawings, and it will be apparent to a person skilled in the art to which the present invention pertains that various substitutions, modifications, and changes are possible within a scope that does not depart from the technical spirit of the present invention.
