Description

Reel type plating equipment {APPARATUS FOR PLATING REEL TYPE MATERIAL}

The present invention relates to a reel-type plating device.

In general, a film is formed on the surface of a steel sheet for various purposes such as strengthening heat resistance and corrosion resistance. There are several methods for forming a film by coating a steel sheet, but the coating operation is performed continuously in the coil state. To do this, a method of passing a steel sheet through a plating tank in which a coating solution containing the material to be coated is stored is mainly used.

In the case of this plating method, the user must continuously process the plating solution and wash the raw materials that require plating, thereby reducing the efficiency of plating.

The technology behind the present invention is disclosed in Republic of Korea Patent Registration No. 10-1481606 (announced on January 12, 2015).

The present invention was developed to solve the above problems, and its purpose is to provide a reel-type plating device for seamlessly plating reel-type materials in a small space.

According to an embodiment of the present invention, a reel supply unit that unwinds and supplies a reel wound on a supply pulley through an uncoiler, is provided at a certain length and is spaced apart from the reel supply unit, and collects the supplied reel and supplies it to the recovery pulley. It is provided between a winding reel recovery part and the reel supply part and the reel recovery part, and includes a reel plating part for plating the reel.

The reel plating unit is each divided into at least one zone, and each zone is formed of a plurality of three stages, and the three stages may be formed in a turn manner.

The reel plating section is formed of a turn 1 stage, a turn 2 stage, and a turn 3 stage, wherein the turn 1 stage is formed of an electrolytic degreasing zone, an electrode washing zone, an oxidation treatment zone, and an ultrasonic cleaning zone, and the turn 2 stage is a first It is formed of a high-speed nickel plating zone and a second high-speed nickel plating zone, and the turn 3 stage can be formed of a gold plating zone and a washing and sealing zone.

The reel plating unit may further include a flushing frame for treating the used solution and a wastewater tank for receiving wastewater that has been processed in the flushing frame at a lower side of the third stage of the turn.

According to the present invention having the above method and features, the reel supply unit, reel plating unit, and reel recovery unit are combined into one device, so it can be placed and used in a narrow space.

In addition, the reel plating portion is formed in a plurality of stages to plate reel-type materials, allowing plating to proceed more quickly in a smaller area than when plating is arranged in a row.

In addition, the area of the reel plating part can be changed and used depending on the plating method, so it can be used correspondingly for a plurality of plating methods.

Figure 1 is a configuration diagram for explaining a plating device according to an embodiment of the present invention, Figure 2 is a diagram for explaining a reel plating unit according to an embodiment of the present invention, and Figure 3 is a diagram according to an embodiment of the present invention. This is a drawing showing the sewer and waste water tank.

1 to 3, the plating device 100 according to an embodiment of the present invention includes a reel supply unit 110, a reel plating unit 120, and a reel recovery unit 130. This plating device 100 is used to provide plating on the surface of the reel while moving the reel, and plating the reel multiple times without stopping the movement of the reel.

The reel supply unit 110 unwinds the reel wound on the supply pulley in the form of a skein through an uncoiler and supplies it to the reel plating unit 120. At this time, the reel is a reel-type material that is wound around the supply pulley in the form of a skein, and the supply pulley is continuously unwound to be provided to the reel plating part. Additionally, the reel wound on the supply pulley is unwound through an uncoiler, and the reel that passes the uncoiler may be formed to have a straight shape so as not to include curvature. Through this uncoiler, the reel wound around the supply pulley can be unwound to more smoothly provide plating on the surface of the reel in the reel plating unit 120, which will be described later.

Next, the reel plating portion 120 is formed in plural pieces into a turn 1 stage 121, a turn 2 stage 122, and a turn 3 stage 123, each of which has a turn 1 stage 121 and a turn 2 stage 122. ) and the turn 3 stage 123 are formed into a plurality of different zones to proceed with different stages.

First, the first stage of the turn (121) is formed of an electrolytic degreasing zone, an electrode washing zone, an oxidation treatment zone, and an ultrasonic cleaning zone, and the second stage of the turn (122) is formed of a first high-speed nickel plating zone and a second high-speed nickel plating zone. The turn 3 stage (123) is formed of a gold plating area, a washing area, and a sealing area.

First, the electrolytic degreasing zone removes contaminants from the reel material and activates the metal surface at the same time. It is degreased by electrolysis using direct current, alternating current, and PR current, which are mainly alkaline degreasing methods. This electrolytic degreasing zone is designed to completely remove dirt on the surface of the reel material and activate the metal surface, and activation is achieved by electrolyzing the component at the anode. In other words, oxygen generated at the anode penetrates the dirt and promotes the removal of these pollutants. Additionally, anodic electrolysis can prevent electrodeposition of impure metals that interfere with plating adhesion. In addition, if the reel material has an oxide film on heat-treated products, welded parts, etc., a double electrolysis method is used depending on the degree of the oxide film. In this case, anodic electrolysis is performed (after pretreatment if necessary), and then the oxide film is removed through pickling. The smarts formed in are removed in the second electrolytic degreasing (final degreasing). The first electrolytic degreasing zone is intended to remove grease and dirt that may interfere with scale removal.

Next, the electrode washing area is immersed in a thin pickling solution as a post-treatment process of electrolytic degreasing to neutralize alkaline residues. That is, in the case of electrolytically degreased reel-type material, it has alkalinity, and if alkalinity continues to exist in the reel-type material, plating problems may occur during later plating, so the alkalinity is neutralized using an acidic solution.

Next, the oxidation treatment area is used to form an oxide film on the reel-type material, and the ultrasonic cleaning area cleans the reel-type material using ultrasonic waves.

Next, the first high-speed nickel plating zone is performed to provide corrosion resistance and improve hardness of the reel-type material, and is electroplating in which nickel ions are deposited on the surface of the reel-type material through electric current. Through this high-speed nickel plating, reel-type materials can be first coated. And when the first high-speed nickel plating zone is completed, the reel-type material is washed using the same washing liquid used in the electrode washing zone previously. At this time, the first high-speed nickel plating can proceed with nickel plating in less than 30 seconds. As plating progresses in this way, the speed of nickel plating can be improved.

Next, in the second high-speed nickel plating zone, further plating is performed using nickel, similar to the first nickel plating zone. As shown in Figure 2, the second high-speed nickel plating zone is formed longer than the first high-speed nickel plating zone in order to plate nickel on the reel-type material through the second high-speed nickel plating.

And when the second high-speed nickel plating zone is completed, foreign substances present on the surface of the reel-type material are removed through electrode washing and ultrasonic washing.

Next, the gold plating area is an area where gold is plated, and gold is plated on the reel-type material on which nickel plating has been completed. Gold plating is used to increase the conductivity of reel-type materials.

In addition, when gold plating is completed, the reel-type material is moved to the washing and repair area. This cleans the surface of the reel-type material on which gold plating has been completed and prevents the plated raw materials present on the surface of the reel-type material from being exported to the outside. We carry out sealing to minimize it.

In addition, the reel plating unit 120 includes a washing frame 124 that processes the solution used on the lower side of the turn 3 stage 123 and a waste water tank 125 that accommodates wastewater that has been processed in the washing frame 124. can do. This washing frame 124 reprocesses the plating solution previously used in the plating area, and in the case of a reusable solution, it is reused in the plating area, and for the plating solution that cannot be reprocessed, the solution is provided to the waste water tank 125. Then, when the waste water tank 125 exceeds a certain amount, the user can replace and reuse the waste water tank 125, and the flushing frame 124 can also be replaced and reused when the treatment capacity is exceeded.

Next, the reel recovery unit 130 dries the reel-type material for which plating has been completed through the reel plating unit 120 and simultaneously winds it around a recoiler into a skein.

The reel supply unit 110 and reel recovery unit 130 supply and retrieve reel-type materials at the same speed, and can preferably provide a moving speed of 35 m/min (35 m per minute). At this time, if the speeds of the reel supply unit 110 and the reel recovery unit 130 are formed differently, the supply of reel-type material may become unstable, which may interfere with reel plating and cause malfunction of the plating device 100. there is.

In addition, in the present invention, the reel plating unit 120 operates by setting a zone for performing a plurality of different steps in the turn 1 stage 121, turn 2 stage 122, and turn 3 stage 123, but the plating process If the type changes, the area can be rearranged to proceed with another plating. That is, the reel plating unit 120 can be provided by changing the zones of the first turn stage 121, the second turn stage 122, and the third turn stage 123. In this way, each stage of the reel plating unit 120 can be changed and provided according to the plating method, so that it can correspond to a plurality of plating methods.

And, as shown in FIG. 1, it may include a regeneration device. The regeneration device in the present invention purifies the used solution through a filter and provides the purified solution back to the reel plating unit 120. By reusing the solution through a regeneration device, the amount of wastewater generated during plating can be reduced.

In addition, the plating device 100 of the present invention is automatically controlled, so that the reel moves from the top to the bottom as it progresses to turn 1, turn 2, and turn 3, and each stage is equipped with a plating and washing tank. Because it is included in an integrated form, plating can be carried out at a faster rate than the existing independent plating method.

And, as shown in Figure 2, a denser is used to maintain the tension of the reel when it is supplied to the plating machine. This denser includes a plurality of rotating rollers, and as the rollers rotate, the reel moves to the surface of the roller to maintain the tension of the reel.

In addition, according to another embodiment, it includes a coating layer applied to the inner surface of each zone, the coating layer is formed of a first layer and a second layer, and the first layer is the inside of the box where odor particles generated during plating are deposited. At the same time as preventing them from adhering to the surface, some odorous particles are removed and a second layer is formed together, preventing scratches on the inside of the loading box by sharp instruments (such as knives) present from the reel plating part 120. Alternatively, by suppressing the formation of dents, it is possible to prevent moisture from entering where there are scratches or dents and causing rust. This first layer includes 10 parts by weight of calcium phosphorylation, 0.3 to 0.89 parts by weight of calcium oxide (Cao), 0.001 to 2.5 parts by weight of copper sulfate (CuSO45H2O), and 0.5 to 3.0 parts by weight of organic and inorganic acids, based on 10 parts by weight of calcium phosphorylation. parts by weight and 0.1 to 0.15 parts by weight of silver oxide, and the second layer contains 10 parts by weight of a perfluorinated compound, 0.11 parts by weight of silicon alkoxide, and octadecyltrichlorosilane based on 10 parts by weight of the perfluorinated compound. It contains 0.5 to 2.0 parts by weight of reactive silane, 0.13 parts by weight of polytetramethylene glycol, 0.1 parts by weight of a photopolymerization initiator, and 2 parts by weight of an organic solvent.

First, phosphorylated calcium is used as a catalyst to increase the reactivity of calcium oxide (CaO), which will be described later, and 10 parts by weight of phosphorylated calcium is preferably used. If less than 10 parts by weight of phosphorylated calcium is used, oxidation, which will be described later, It may reduce the reactivity of calcium, and if more than 10 parts by weight of calcium phosphorylation is used, it may further promote the reaction of calcium oxide, which will be described later, and cause a rejection reaction to other additives. And this phosphorylated calcium can be hydroxyapatite or calcium phosphate.

Next, calcium oxide (CaO) is generally used for sanitary disinfection, and reacts with water to produce a high temperature of 80°C or higher. Based on 10 parts by weight of calcium phosphate, a mixing amount of 0.3 to 0.89 parts by weight of calcium oxide is preferable. If the calcium phosphorylation content is less than 0.3 parts by weight, the sterilizing power of malodor particles that generate bad odors decreases, and on the contrary, if the calcium phosphorylation content is more than 0.89 parts by weight, a unique odor of calcium oxide is generated and other Rejection reactions may occur with additives present in the first layer.

Next, copper sulfate (CuSO ₄ 5H ₂ O) is a composition that removes bad odors and is a blue transparent crystal with a specific gravity of 2.286. In dry air, it gradually loses moisture and turns into powder. At 45℃, it loses 2 molecules of water, at 110℃, it loses 4 molecules of water, and again at 250℃, it loses all water molecules and becomes a colorless anhydride. As a preferred embodiment of the present invention, it is preferable that 0.001 to 2.5 parts by weight of copper sulfate be contained based on 10 parts by weight of calcium phosphorylation. At this time, if less than 0.001 parts by weight of copper sulfate is used, the concentration of copper ions is low, so there is virtually no deodorizing effect on acid odor. Conversely, if copper sulfate is used in excess of 2.5 parts by weight, crystals are formed from the supersaturated copper sulfate solution. The effect of removing bad odors described in the present invention is reduced.

Next, organic and inorganic acids activate the copper and sulfate ions contained in copper sulfate, and organic and inorganic acids such as sulfuric acid, nitric acid, hydrochloric acid, acetic acid, citric acid, salicylic acid, tartaric acid, maleic acid, lactic acid, malic acid, and ascorbic acid. You can choose one or more of them and use them in combination. As a preferred embodiment of the present invention, based on 10 parts by weight of calcium phosphorylation, it is preferable that 0.5 to 3.0 parts by weight of organic and inorganic acids are contained. If these organic and inorganic acids are used in amounts less than 0.5 parts by weight, they fail to activate copper and sulfate ions when applied to odor sources at low concentrations, and if more than 30 parts by weight are used, the solubility of copper sulfate decreases. Crystals precipitate, and by precipitating these crystals, the activation of copper and sulfate ions can be reduced.

Next, silver oxide is used to increase the reactivity of copper sulfate, and it is preferable that 0.1 to 0.15 parts by weight of silver oxide is contained based on 10 parts by weight of calcium phosphorylation. Here, when less than 0.1 parts by weight of silver oxide is used, the reaction of copper sulfate is reduced, and when more than 0.15 parts by weight is used, the solubility of copper sulfate is reduced, which may reduce the activation of copper sulfate.

In other words, as the first layer is formed on the inner surface of each zone, calcium oxide reacts with water and generates a high temperature of 80 degrees or more, and sterilization proceeds at the same time. Calcium oxide provides a rapid reaction and at the same time, copper sulfate By forming a high level of reactivity between organic and inorganic acids and activating copper and sulfate ions, bad odors are eliminated. At this time, calcium oxide may be activated by moisture present on the inner surface of each zone, or may be activated through moisture contained in the incoming object.

Next, the second layer is applied to prevent scratches from forming on the inner surface of each zone, prevent moisture from entering the scratched area, and suppress rust from forming on the inner surface of each zone. It is applied to the top surface between the ground floor and the interior surface of each section. This second layer is 10 parts by weight of a perfluorinated compound, based on 10 parts by weight of the perfluorinated compound, 0.11 parts by weight of silicon alkoxide, 0.5 to 2.0 parts by weight of reactive silane containing octadecyltrichlorosilane, and polytetramethylene. It contains 0.13 parts by weight of glycol, 0.1 parts by weight of photopolymerization initiator, and 2 parts by weight of organic solvent.

First, the perfluorinated compound is used as a water-repellent coating agent to prevent moisture or water from entering the inner surface of each area, and is used together with an inorganic antibacterial agent made of inorganic substances. It is desirable to use 10 parts by weight of the perfluorinated compound. However, if the perfluorinated compound is used in an amount less than 10 parts by weight, the water-repellent function may be reduced, and if it is used in an amount greater than 10 parts by weight, a precipitate is formed and the water-repellent coating is damaged. coating power may be lost.

Next, silicon alkoxide is used to increase the binding force of the perfluorinated compound to the inner surface of each zone, and it is preferable to use 0.11 parts by weight of silicon alkoxide based on 10 parts by weight of the perfluorinated compound. If the silicon alkoxide is used in a smaller amount than 0.11 parts by weight, the adhesion of the perfluorinated compound to the inner surface of each zone may be reduced, and if the silicon alkoxide is used in a larger amount than 0.11 parts by weight, the transparency may be reduced. there is.

Next, the reactive silane includes octadecyltrichlorosilane (CH3(CH2)17SiCl3), and is used to facilitate the reaction of silicon alkoxide and to reduce the critical tilt angle. The reactive silane included for this purpose is preferably used in an amount of 0.5 to 2.0 parts by weight, based on 10 parts by weight of the perfluorinated compound. When the reactive silane is used in less than 0.5 parts by weight, the reactivity of the silicon alkoxide decreases, and when it is used in more than 2.0 parts by weight, the critical inclination angle increases and the reactivity decreases.

Next, polytetramethylene glycol has a glass transition temperature of 50 degrees or more and a hardness value of 60 or more. That is, by using polytetramethylene glycol, the second layer can be provided with a high hardness value even at a high temperature of 80 degrees or higher. The polytetramethylene glycol is preferably used in an amount of 0.13 parts by weight, based on 10 parts by weight of the perfluorinated compound. If the polytetramethylene glycol is used in an amount greater or less than 0.13 parts by weight, there is a disadvantage in that it is difficult to have a glass transition temperature and a high hardness value of the second layer.

Next, the photopolymerization initiator is used to cure polytetramethylene glycol by curing it using ultraviolet rays, and is used to accelerate the curing speed. It is preferable to use 0.1 parts by weight of this photopolymerization initiator based on 10 parts by weight of the perfluorinated compound. If the photopolymerization initiator is used in less than 0.1 parts by weight, the curing of the polytetramethylene glycol is not sufficiently formed, and if the photopolymerization initiator is used in more than 0.1 parts by weight, the curing of the polytetramethylene glycol is excessive. This makes it difficult to obtain the desired hardness value.

Next, the organic solvent is used to form polytetramethylene glycol into a liquid substance and may include ether, acetone, or alcohol. It is preferable to have 2 parts by weight of this organic solvent based on 10 parts by weight of the perfluorinated compound. If less than 2 parts by weight of the organic solvent is used, polytetramethylene glycol is less liquefied, and if more than 2 parts by weight of the organic solvent is used, curing of polytetramethylene glycol progresses slowly.

The present invention described above with reference to the accompanying drawings is capable of various modifications and changes by those skilled in the art, and such modifications and changes not limited by the claims should be construed as being included in the scope of rights of the present invention.
