Description

Partially CLOSED SHADING DEVICE FOR BLOCKING SCATTERING DUST IN SHIP STRUCTURES

The present invention is a partially closed type shielding device for blocking scattering dust of ship structures, and scattering dust and by-products It is an invention that prevents leakage to the outside.

On the surface of the ship, there are sand, oil components, mill scale, metal oxides (rust), etc. which are incorporated during manufacture, processing, and/or installation or formed during operation. Mill scale refers to a black or black-brown oxide film formed on the surface of steel when a steel material such as carbon steel is heated and processed to 800° C. or higher. In particular, as the operating time of the facility elapses, corrosion occurs on the outer plate of a ship made of a corrosive metal such as iron or iron alloy, and inevitably, an oxide of these metals, for example, iron oxide, which can be referred to as rust or scale (Hereinafter, mill scale, rust, or scale is simply referred to as 'scale' for convenience) is formed and begins to deposit on the surface. When such scale is deposited on the shell plate of a ship, the flow of fluid flowing in the shell plate is locally stagnated, which can cause a decrease in facility design efficiency and even a safety accident due to pressure generation. In addition, if the corrosion of the ship's shell plate due to scale formation accelerates, damage to equipment and ship accidents may occur.

Therefore, in order to obtain the normal design efficiency of the facility and to prevent possible accidents, the ship's shell should be kept clean before starting normal operation or on a regular basis, and if necessary, the ship's shell should be repaired through painting. For this purpose, it is necessary to remove and repair foreign substances such as scale and grease on the ship's shell by selecting and implementing the most suitable pre-treatment method according to the characteristics and conditions of the facility.

Painting work for repairing the ship's shell requires a pre-jeopardy work.

Pre-treatment operation, commonly referred to as surface treatment, is important for the optimum life of the paint, and for long-term protection, the surface must be treated with good and permanent adhesion in mind, and the surface is cleaned for adhesion of the paint it is necessary to do

In addition, since proper pretreatment determines the success or failure of coating, polishing and pretreatment should be considered in a close relationship. There are degreasing, derusting (cheongrak) and chemical conversion treatment methods for pretreatment.

This pre-treatment process removes scale such as rust, while scattering dust such as dust is generated. Fugitive dust not only causes pollution of the surrounding environment, but also has a problem of damaging public health and air environment resources.

In order to solve these problems of scattering dust, the Ministry of Environment publishes scattering dust management manuals and checklists to prevent harm to public health and the environment caused by scattering dust, and strives to preserve air environment resources sustainably.

However, the scattering dust generated from the outer plate of the ship is being directly discharged into the atmosphere without a specific outlet by working in an open space.

To solve this problem, a sprinkler wheel and dust collector are used to solve this problem, but there is a limit to dust collection due to the characteristic of an open space.

Therefore, when working on the ship's shell, it is necessary to close the working surface to prevent the spread of scattering dust, and to efficiently collect and process scattering dust in the ship structure. the current situation.

A basket 110 or a scaffold is installed and used.

The present invention closes a part of the outer plate of the ship to form a shielding space to prevent scattering dust and by-products generated during work in the shielded space from leaking to the outside,

In the state in which the present invention is installed in the high-altitude vehicle 100, it is moved to the outer plate of the ship that requires work.

Referring to FIG. 7 , the adjusting part 430 of the cylinder part 400 is connected to the mesh part 210 to move the mesh part 210 in the direction of the shell plate of the ship to bring the mesh part 210 into contact with the shell plate of the ship. to shield part of the outer plate.

This prevents scattering dust and by-products from leaking to the outside, and it can be tightly closed in response to the curvature of the outer plate of the ship.

Here, the other end 433 of the adjusting unit of the cylinder part 400 is in magnetic contact with the outer plate of the ship, and is magnetically contacted and coupled to the outer plate of the ship to increase the coupling force, and the mesh portion 210 is also in contact with the outer plate of the ship during work. It can be fixed so as to be in contact with

The operator can carry out the shell plate work of the ship inside the blocking booth unit 300, and in proceeding the shell plate operation, the scattering net 200 is a risk factor that may occur in the shell plate of the ship, that is, barnacles, attachments, Corrosive material bounces on the inner surface of the blocking booth 300 and absorbs the kinetic energy that bounces off the user through the repulsive force, thereby significantly reducing the risk of injury.

This may be implemented differently according to the intention of a designer and a user, and may be applied differently, such as a conventional ventilation device, a purification device, and an air conditioner.

The operator collects scattering dust, which is a by-product of the ship's shell work, inside the blocking booth unit 300, and it can be collected through an appropriate process treatment.

In addition, even if paint is sprayed for painting work and washing of the ship's shell, it is collectively collected through the hopper unit 500 to prevent contamination of the planting environment and also prevent environmental pollution.

In addition, the blocking booth unit 300 of the present invention has a disadvantage in that it is vulnerable to corrosion because it is mainly in contact with factors that can cause various corrosion, such as the ocean, pretreatment agents, and solvents.

Accordingly, a coating layer is formed on the surface of the blocking booth unit 300 of the present invention through an anti-corrosion coating to prevent corrosion.

The coating layer (not shown) is to be coated using a coating composition, and the coating layer using the coating composition may exhibit an anti-corrosion effect. Specifically, the coating layer is formed on the surface of the blocking booth unit 300 by the coating layer to prevent external exposure of the blocking booth unit 300, and contains a metal with a higher ionization tendency than the blocking booth unit 300. , it is possible to prevent corrosion of the blocking booth unit 300 .

More specifically, the coating composition of the present invention may include a siloxane-based compound represented by the following Chemical Formula 1; organic solvents, metal compounds and amine compounds:

[Formula 1]

Here, n is an integer from 1 to 100.

When the coating layer is formed on the surface of the blocking booth unit 300 using the coating composition of the present invention, the adhesive force with the blocking booth unit 300 is excellent, so that the coating layer is not easily peeled off by an external force, and the blocking booth unit 300 ), as it contains a metal compound having a higher ionization tendency than that, it can exhibit an excellent anti-corrosion effect.

Specifically, the siloxane-based compound not only exhibits excellent adhesion to the blocking booth unit 300 , but also maintains the viscosity of the coating composition at a certain level to increase moldability and enhance stability.

The metal compound serves as an erosion and corrosion inhibitor that blocks contact with moisture, salt or oxygen. Here, the metal compound may use a metal having a higher ionization tendency than iron in order to act as an erosion and corrosion inhibitor. That is, a metal or alloy such as aluminum (Al), magnesium (Mg), or zinc (Zn) may be used, and zinc (Zn) is mainly used.

The particle size of the metal compound may be 0.1 to 10㎛. When the particles of the metal compound are 0.1 μm or more, the manufacturing cost of the metal compound can be reduced, and when the particles of the metal compound are 10 μm or less, the metal particles can be uniformly dispersed.

The organic solvent is selected from the group consisting of methyl ethyl ketone (MEK), toluene, and mixtures thereof, and preferably methyl ethyl ketone may be used, but is not limited thereto.

The amine compound may include modified aliphatic amines or tertiary amines, and specifically, trimethylamine or aniline may be used. The amine compound may be included in the coating composition to prevent cracking or peeling of the coating film. That is, by increasing the adhesion of the coating layer, the effect of preventing cracking or peeling of the coating film according to use is excellent.

The coating composition may further include a stabilizer as other additives, and the stabilizer may include a UV absorber, an antioxidant, and the like, but is not limited to the above examples and may be used without limitation.

For forming the coating layer, the coating composition may include a siloxane-based compound represented by Formula 1 below; organic solvents, metal compounds and amine compounds.

The coating composition may include 40 to 60 parts by weight of the siloxane compound represented by Formula 1, 20 to 40 parts by weight of the metal compound, and 5 to 15 parts by weight of the amine compound, based on 100 parts by weight of the organic solvent. In the case of the above range, a synergistic effect is expressed to the extent that the water repellency effect due to the interaction of each component has a critical significance, and when it is out of the above range, the synergistic effect is rapidly reduced or almost absent.

More preferably, the viscosity of the coating composition is 1500 to 1800 cP, and when the viscosity is less than 1500 cP, when it is applied to the surface of the blocking booth part 300, it flows down and the formation of the coating layer is not easy, and it exceeds 1800 cP In this case, there is a problem in that the formation of a uniform coating layer is not easy.

[Preparation Example 1: Preparation of coating layer]

1. Preparation of coating composition

A coating composition was prepared by mixing methyl ethyl ketone with a siloxane-based compound represented by the following Chemical Formula 1, zinc and trimethylamine:

Here, n is an integer from 1 to 100.

A more specific composition of the coating composition is shown in Table 1 below.

(unit parts by weight)

2. Preparation of coating layer

Typically, an experiment was conducted using aluminum, which is a metal material that easily corrodes, instead of the blocking booth unit 300 .

After coating the coating composition of DX1 to DX5 on one surface of 10 × 10 cm aluminum, it was cured to form a coating layer.

Experimental example

1. Evaluation of surface appearance

Due to the difference in viscosity of the coating composition, after the coating layer was prepared, sensory evaluation was performed on whether a uniform surface was formed. Whether or not a uniform coating layer was formed was evaluated, and evaluation was performed according to the following criteria.

○: uniform coating layer formation

×: Formation of a non-uniform coating layer

TX1 TX2 TX3 TX4 TX5 sensory evaluation × ○ ○ ○ ×

When the coating layer is formed, if the viscosity is less than a certain level, a flow occurs on the surface of the blocking booth unit 300, so that it is difficult to form a uniform coating layer after the curing process. Accordingly, there may be a problem in that the production yield is lowered. In addition, even when the viscosity is too high, it is difficult to uniformly apply the composition to form a uniform coating layer.

2. Measurement of corrosion properties

In order to confirm the corrosion characteristics, an aluminum plate without a coating layer was used as a control, and corrosion resistance tests were performed using an aluminum plate with a coating layer of TX1 to TX5.

The aluminum plate was immersed in a beaker containing a 10 wt% CuCl2 aqueous solution, and the degree of corrosion was checked over time.

If the generation of hydrogen gas is confirmed with the naked eye, it will mean that corrosion occurs, and it was confirmed whether corrosion occurred until 24 hours had elapsed.

○: Corrosion

×: No corrosion

TX1 TX2 TX3 TX4 TX5 control corrosion occurs ○ × × × × ○

As a result of the experiment, it was confirmed that the control aluminum plate was placed in a beaker and hydrogen gas was generated shortly thereafter, and copper was precipitated in less than 1 hour. In the case of TX1, hydrogen gas was generated after 3 hours, and copper precipitation was confirmed after 6 hours.

In the case of other coating layers, corrosion did not occur even after 24 hours had elapsed, and it was confirmed that there was an excellent effect in preventing corrosion.
