Description
본 발명은 도금욕 침적롤의 드로스 세정액 조성물에 관한 것이고, 특히 도금욕 침적롤(roll) 표면의 용사층을 손상시키지 않고 세정을 행하여, 롤 표면에 부착한 드로스(dross) 등의 부착물을 효과적으로 제거할 수 있는 드로스 세정액 조성물에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dross cleaning liquid composition of a plating bath immersion roll, and in particular, cleaning is carried out without damaging the sprayed layer on the surface of the plating bath immersion roll, thereby adhering a deposit such as dross attached to the roll surface. The present invention relates to a dross cleaning liquid composition that can be effectively removed.
종레에 연속 용융아연 도금공정은 생산성과 경제성이 우수하기 때문에 얇은 강판의 부식방지를 위한 일반적인 피막형성 공정으로 알려져 있다. 그런데, 도금욕에 침적된 도금장치와 도금소재인 강판은 용융아연과 반응하여 심하게 부식되어 금속간 화합물이나 산화물을 형성하게 되는데 이를 드로스라 한다.The continuous hot dip galvanizing process on a bell is known as a general film forming process for preventing corrosion of thin steel sheets because of its excellent productivity and economic efficiency. However, the plating apparatus deposited on the plating bath and the steel plate, which is a plating material, are severely corroded by reacting with molten zinc to form an intermetallic compound or oxide, which is called dross.
이러한 드로스는 작업중 통판과 물 회전에 의해 도금욕 내에서 교반, 부상 및 유동되면서 롤 표면에 계속적으로 부착 또는 고착하여 제품에 덴트(dent)성 표면결함 및 프레스 가공시 흠집을 유발하는 요인으로 작용한다.This dross is a factor that causes dent surface defects and scratches during press working by continuously adhering or sticking to the roll surface while stirring, floating, and flowing in the plating bath by rotating the plate and water during operation. .
한편, 용융도금욕 침적롤의 표면은 내식성 및 내마모성을 위해 용사처리가 되어 있으므로, 용사피막을 손상시키지 않고 드로스를 제거하는 방법이 필요하다.On the other hand, since the surface of the hot dip coating roll is sprayed for corrosion resistance and wear resistance, a method of removing dross without damaging the thermal spray coating is required.
이와 같이 드로스를 제거하기 위한 기술은 도금욕에서 꺼내진 롤 표면을 가열하면서 망치로 충격을 가하는 충격박리 방법과 비교적 고농도의 산용액에 침적시켜 드로스를 용해시키는 용해박리 방법(JP 95-90528, JP 95-224365) 등이 공지되어 있다.As such, the technique for removing dross is an impact peeling method in which a surface of a roll taken out of the plating bath is heated and hammered and a dissolution peeling method in which dross is dissolved by depositing in a relatively high concentration of acid solution (JP 95-90528). JP 95-224365).
그러나, 상기 충격박리 방법은 롤 표면 부착 드로스의 미세한 부분까지는 제거하기 힘들 뿐 아니라 충격에 의해 용사층이 손상되는 문제가 있다. 또한, 용해박리 방법은 드로스가 부착된 롤을 1.5∼10wt%의 황산 또는 염산 용액에 20∼180분 침적하는 방법(JP 95-90528)과 인산용액을 롤 표면에 분사하는 방법(JP 95-224365) 등이 공지되어 있다. 그러나, 이러한 방법들은 모두 산에 의해서 롤의 축수 부분과 같은 비용사면이 부식되는 문제와 용사층이 열화되는 문제 그리고 일부 불용성 드로스가 잔존하는 문제를 수반하므로 적합하지가 않다.However, the impact peeling method is difficult to remove even the minute portion of the roll surface attached dross, and there is a problem that the sprayed layer is damaged by the impact. In addition, the dissolution separation method is a method of immersing a dross-coated roll in a solution of 1.5-10 wt% sulfuric acid or hydrochloric acid for 20 to 180 minutes (JP 95-90528) and spraying a phosphoric acid solution on the roll surface (JP 95-224365). ) And the like are known. However, all of these methods are not suitable because they involve acid corrosion problems such as the bearing part of the roll, deterioration of the spray layer, and the problem of some insoluble dross remaining.
이에 본 발명자들은 상기 종래 세정액의 문제점을 해결하기 위해 연구와 실험을 거듭하고 그 결과에 근거하여 본 발명을 제안하게 된 것으로, 본 발명은 세정시 비용사면의 부식, 용사층의 열화 및 불용성 드로스의 잔존 문제를 현저히 제거시킬 수 있는 세정액 첨가제를 첨가한 드로스 세정액 조성물을 제공하는데 그 목적이 있다.In order to solve the problems of the conventional cleaning solution, the present inventors have repeatedly studied and experimented and proposed the present invention based on the results. The present invention provides a corrosion of the cost slope during cleaning, deterioration of the sprayed layer, and an insoluble dross. It is an object of the present invention to provide a dross cleaning liquid composition to which a cleaning liquid additive capable of remarkably eliminating the problem of residual addition is added.
상기 목적을 달성하기 위하여, 본 발명에 따르면 첨가제가 함유된 도금용 침적롤의 드로스 세정액에 있어서, 상기 첨가제는 아세트산[CH3COOH] 및 1-클로로옥타데칸[CH3(CH2)17C1] 중에서 선택된 1종 또는 2종의 화합물과 상용 부식억제제의 혼합물로 이루어져 있는 것을 특징으로 한다.In order to achieve the above object, according to the present invention, in the dross cleaning liquid of the plating roll containing the additive, the additive is acetic acid [CH 3 COOH] and 1-chlorooctadecane [CH 3 (CH 2 ) 17 C1 ] A mixture of one or two compounds selected from commercially available corrosion inhibitors.
이하, 본 발명을 더욱 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
일반적으로, 침적롤 표면에 부착되어 있는 아연 및 미량의 Fe-Al-Zn 계 드로스를 유기산 또는 무기산 수용액으로 세정하면 아연을 제외한 드로스 성분이 잘 용해되지 않는다.In general, when the zinc and trace amounts of Fe—Al—Zn based dross attached to the immersion roll surface are washed with an aqueous solution of an organic acid or an inorganic acid, dross components other than zinc are not easily dissolved.
그러나, 본 발명에 따른 첨가제가 상기 유기산 또는 무기산 수용액에 추가로 첨가되어 있는 경우에는, 드로스의 분해반응이 촉진되어 세정능이 향상되고, 본 발명에서는 이러한 세정액의 첨가제로서 다음과 같은 물질들을 특정하고 있다.However, when the additive according to the present invention is additionally added to the aqueous organic or inorganic acid solution, the decomposition reaction of the dross is promoted to improve the cleaning performance, and in the present invention, the following substances are specified as additives of the cleaning liquid. have.
먼저, 본 발명에서는 아세트산[CH3COOH]을 첨가제로 사용한다.First, acetic acid [CH 3 COOH] is used as an additive in the present invention.
상기 아세트산은 특히 드로스의 분해반응을 촉진하는 효과를 가지고 있으며, 아연의 용해반응도 어느 정도 촉진시킨다. 그 함량이 0.05g/L 미만으로 함유되면 그 효과가 충분히 발휘되지 못하고, 20g/L를 초과하면 효과가 포화되므로 이 이상의 첨가는 경제성을 저하시키기 때문에 바람직하지 못하다 따라서, 본 발명에서는 상기 아세트산이 유기산 또는 무기산 수용액으로 구성된 세정액에 0.05-20g/L의 범위로 함유되는 것이 바람직하다.The acetic acid in particular has the effect of promoting the decomposition reaction of dross, and also to some extent to promote the dissolution reaction of zinc. If the content is less than 0.05 g / L, the effect is not sufficiently exhibited. If the content is more than 20 g / L, the effect is saturated. Therefore, the addition of more than this is not preferable because it lowers the economic efficiency. Therefore, in the present invention, the acetic acid is an organic acid. Or it is preferable to contain in the washing | cleaning liquid which consists of aqueous inorganic acid solution in the range of 0.05-20 g / L.
다음으로, 본 발명에서는 1-클로로옥타데칸[CH3(CH2)17C1]을 첨가제로 사용한다. 상기 1-클로로옥타데칸은 상기한 아세트산과 마찬가지로 드로스의 분해반응을 촉진하는 효과를 가지고 있으며, 아연의 용해반응도 어느 정도 촉진시킨다. 그 함량이 0.05g/L 미만인 경우에 그 효과가 충분히 발휘되지 못하고, 20g/L를 초과하면 그 효과가 포화하여 그 이상의 첨가는 경제성을 저하시키기 때문에 바람직하지 못하다. 따라서, 본 발명에서는 상기 1-클로로옥타데칸이 유기산 또는 무기산 수용액으로 구성된 세정액에 0.05-20g/L의 범위로 함유되는 것이 바람직하다.Next, in the present invention, 1-chlorooctadecane [CH 3 (CH 2 ) 17 C1] is used as an additive. The 1-chlorooctadecane has the effect of accelerating the decomposition reaction of dross like acetic acid described above, and also promotes the dissolution reaction of zinc to some extent. If the content is less than 0.05 g / L, the effect is not sufficiently exhibited. If the content is more than 20 g / L, the effect is saturated, and further addition is not preferable because it lowers the economic efficiency. Therefore, in this invention, it is preferable that the said 1-chlorooctadecane is contained in the washing | cleaning liquid which consists of aqueous organic or inorganic acid solution in the range of 0.05-20 g / L.
본 발명에서는 상술한 바와 같은 화합물중 1종을 선택하여 세정액에 함유시킴으로써, 본 발명에서 목적하는 드로스의 세정시 비용사면의 부식, 용사층의 열화 및 불용성 드로스의 잔존 문제를 현저히 제거시킬 수 있다.In the present invention, by selecting one of the compounds described above in the cleaning liquid, it is possible to remarkably eliminate the problems of corrosion of the non-slope, deterioration of the sprayed layer and insoluble dross during the cleaning of the dross desired in the present invention. have.
또한, 본 발명에서는 상술한 바와 같이 화합물 2종을 선택하여 세정액에 함유시킴으로써, 본 발명에서 목적하는 드로스의 세정시 비용사면의 부식, 용사층의 열화 및 불용성 드로스의 잔존 문제를 현저히 제거시킬 수 있다. 이때, 선택되는 2종의 화합물에 대한 배합비율은 목적하는 바에 따라 임의로 행할 수 있으며, 선택된 2종의 화합물은 세정액에 0.05-20g/L의 함유량으로 포함되는 것이 바람직하다. 그 이유는 0.05g/L 이하의 농도에서는 드로스 세정에 미치는 첨가제의 효과가 미미하고, 20g/L를 초과할 경우에는 효과가 포화되어 더 이상의 첨가는 경제성을 저하시키며, 용액의 안정성을 저하시키는 경향을 보이기 때문이다.In addition, in the present invention, by selecting two compounds as described above and containing them in the cleaning liquid, it is possible to significantly eliminate the problem of corrosion of the inclined surface, deterioration of the sprayed layer, and residual insoluble dross during the cleaning of the dross desired in the present invention. Can be. In this case, the compounding ratio for the two selected compounds can be arbitrarily carried out as desired, and the two selected compounds are preferably contained in a content of 0.05-20 g / L in the washing liquid. The reason is that when the concentration is 0.05g / L or less, the effect of the additive on the dross cleaning is insignificant, and when the concentration exceeds 20g / L, the effect is saturated, and further addition decreases the economical efficiency and the stability of the solution. This is because there is a tendency.
상술된 바와 같이, 상기 화합물 중에서 1종 또는 2종의 선택된 첨가제는 물 또는 기타 용액과 혼합하여 용액형이나 분말형으로 농축하여 사용할 수도 있으며, 이들 첨가제를 유기산 또는 무기산 수용액에 첨가하는 경우에도 상술한 바와 같은 함량이 되도록 함유시키는 것이 바람직하다.As described above, one or two selected additives of the compounds may be mixed with water or other solutions to be concentrated and used in solution or powder form, and the above-described additives may be added to an organic or inorganic acid aqueous solution. It is preferable to make it into content as it is.
또한, 상기 화합물 중에서 1종 또는 2종의 선택된 첨가제가 사용되는 산세용부식억제제와 함께 사용되는 경우 그 효과를 더욱 높일 수 있다.In addition, when one or two selected additives of the compound is used together with the pickling corrosion inhibitor is used, the effect can be further enhanced.
이하, 실시예를 통하여 본 발명을 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to Examples.
