Description

鋁合金陽極處理硫酸電解液分析系統 Aluminum alloy anode treatment sulfuric acid electrolyte analysis system

本發明係關於一種電解槽液成分檢驗,尤指一種透過計算公式分析電解槽液成分濃度之鋁合金陽極處理硫酸電解液分析系統。 The present invention relates to an electrolytic bath liquid composition inspection, especially an aluminum alloy anode treatment sulfuric acid electrolyte analysis system for analyzing the electrolytic bath liquid composition concentration through calculation formula.

鋁及鋁合金在大氣中雖能自然形成一層氧化膜,但膜薄(40~50A)而疏鬆多孔,為非晶態的、不均勻也不連續的膜層,不能作為可靠的防護一裝飾性膜層。隨著鋁製品加工工業的不斷發展,在工業上越來越廣泛地採用陽極氧化或化學氧化的方法,在鋁及鋁合金製件表面生成一層氧化膜,以達到防護一裝飾的目的。 Although aluminum and aluminum alloys can naturally form an oxide film in the atmosphere, the film is thin (40~50A) and loose and porous. film layer. With the continuous development of the aluminum product processing industry, anodizing or chemical oxidation methods are more and more widely used in the industry to form an oxide film on the surface of aluminum and aluminum alloy parts to achieve the purpose of protection and decoration.

其中,陽極氧化處理是利用電化學的方法,在適當的電解液中,以鋁合金零件為陽極,不鏽鋼、鉻、或導電性電解液本身為陰極,在一定電壓電流等條件下,使陽極端表面發生電解氧化反應,從而使工件表面獲得陽極氧化膜的過程。 Among them, anodizing treatment is the use of electrochemical methods. In an appropriate electrolyte, aluminum alloy parts are used as the anode, stainless steel, chromium, or the conductive electrolyte itself is the cathode. Under certain voltage and current conditions, the anode terminal is The electrolytic oxidation reaction occurs on the surface, so that the surface of the workpiece obtains an anodized film.

目前國內外廣泛使用的陽極氧化工藝就是硫酸陽極氧化,和其他方法相比他在生產成本、氧化膜特點和效能上都具有很大優勢,它成本低、膜的透明性好、耐腐蝕耐摩擦性好、著色容易等優點。它是以稀硫酸作電解液,對產品進行陽極氧化,膜的厚度可達5um-20um,膜的吸附性好,無色透明,工藝簡單,操作方便。 At present, the widely used anodizing process at home and abroad is sulfuric acid anodizing. Compared with other methods, it has great advantages in production cost, oxide film characteristics and performance. It has low cost, good film transparency, corrosion resistance and friction resistance. Good sex, easy to color and so on. It uses dilute sulfuric acid as the electrolyte to anodize the product, the thickness of the film can reach 5um-20um, the film has good adsorption, colorless and transparent, simple process and convenient operation.

陽極氧化過後氧化膜的品質決定了產品的品質-精緻的外 觀、耐磨耐腐蝕的特性,所以在生產過程中,操作條件要求十分嚴格,鋁和鋁合金的陽極氧化膜(AAO)的成膜影響因素包含: The quality of the oxide film after anodization determines the quality of the product-exquisite exterior Therefore, in the production process, the operating conditions are very strict. The factors affecting the film formation of the anodic oxide film (AAO) of aluminum and aluminum alloys include:

(1)電解液成分-游離硫酸濃度 (1) Electrolyte composition - free sulfuric acid concentration

游離硫酸濃度對氧化膜的阻擋層厚度、電解液的導電性和對氧化膜的溶解作用、氧化膜的耐蝕性和耐磨性以及後續處理的封孔品質都將產生一定影響。游離硫酸濃度高,對氧化膜的溶解作用大,形成的阻擋層則薄,維持一定電流密度則所需的電壓降低;當游離硫酸濃度低時阻擋層則厚,所需的電壓升高。另外,硫酸濃度高,對氧化膜的溶解作用大,氧化膜的膜孔錐度大、外層孔徑增大,使封孔困難,容易產生粉化的現象,但適當的濃度有利於染色速度,所以要依各自需求設定。 The concentration of free sulfuric acid will have a certain influence on the thickness of the barrier layer of the oxide film, the conductivity of the electrolyte and the dissolution of the oxide film, the corrosion resistance and wear resistance of the oxide film, and the sealing quality of the subsequent treatment. When the concentration of free sulfuric acid is high, the dissolving effect on the oxide film is large, and the formed barrier layer is thin, and the voltage required to maintain a certain current density decreases; when the concentration of free sulfuric acid is low, the barrier layer is thick, and the required voltage increases. In addition, the high concentration of sulfuric acid has a great dissolving effect on the oxide film, the taper of the film pore of the oxide film is large, and the outer pore diameter increases, making it difficult to seal the hole and easy to produce the phenomenon of chalking, but the appropriate concentration is conducive to the dyeing speed, so it is necessary to Set according to your needs.

(2)電解液成分-鋁離子濃度 (2) Electrolyte composition - aluminum ion concentration

鋁離子濃度增加時,會影響到游離酸的導電度,而使得成膜效率變差,當鋁離子含量太高時會影響氧化膜的品質,使得氧化膜的耐磨性和耐蝕性都會下降。 When the concentration of aluminum ions increases, the conductivity of the free acid will be affected, and the film formation efficiency will be deteriorated. When the content of aluminum ions is too high, the quality of the oxide film will be affected, and the wear resistance and corrosion resistance of the oxide film will decrease.

(3)槽液溫度。 (3) The temperature of the bath liquid.

在陽極氧化過程中,會持續產生熱量,必須對槽液進行冷卻降溫,以維持固定溫度範圍,該溫度又以氧化膜的需求來設定。溫度較低時,所產生的膜比較硬,隨著溫度升高,膜較軟比較不容易破裂且較容易染色但因為染色速度太快容易有顏色不均的問題,而且膜的外層硬度較低。高溫產生的膜容易出現“粉化”現象。 During the anodizing process, heat will continue to be generated, and the bath must be cooled to maintain a fixed temperature range, which is set according to the needs of the oxide film. When the temperature is low, the resulting film is relatively hard. As the temperature increases, the film is softer and less prone to cracking and is easier to dye. However, because the dyeing speed is too fast, it is easy to have uneven color problems, and the hardness of the outer layer of the film is relatively low. . The film produced at high temperature is prone to "powder" phenomenon.

(4)氧化電壓以及氧化電流密度 (4) Oxidation voltage and oxidation current density

陽極氧化的氧化電壓決定氧化膜的膜孔的數量、孔徑大小,低電壓生 成的膜孔徑小、孔數多,而高電壓使膜孔徑大,但孔數少。在一定範圍內高電壓有利於生成緻密、均勻的膜。氧化電流密度與生產效率有直接的關係。當採用較高氧化電流密度時,得到預定厚度氧化膜所需時間可以縮短,生產效率高,相對的需要較大的電源供應量,而且需要較大功率的冷卻系統。此外氧化電流密度過高,使膜厚波動大,吊掛點的通電量過大會引起工件“燒傷”。膜層耐蝕性、耐磨性與電流密度的關係也很大。 The oxidation voltage of anodic oxidation determines the number and pore size of the film pores of the oxide film. The resulting membrane has a small pore size and a large number of pores, while the high voltage makes the membrane pore size large but the number of pores is small. A high voltage within a certain range is beneficial to the formation of dense and uniform films. The oxidation current density is directly related to the production efficiency. When a higher oxidation current density is used, the time required to obtain an oxide film with a predetermined thickness can be shortened, the production efficiency is high, and a relatively large power supply is required, and a high-power cooling system is required. In addition, the oxidation current density is too high, which makes the film thickness fluctuate greatly, and the excessive current of the hanging point will cause the workpiece to be "burned". The corrosion resistance and wear resistance of the film are also closely related to the current density.

(5)電解槽液攪拌 (5) Stirring of electrolytic bath solution

為了使陽極氧化槽液溫度和濃度均勻,即時將氧化膜附近的大量熱量帶走,避免溫度持續累積容易產生氧化膜粉化的現象,一般在陽極氧化過程中對槽液進行攪拌。 In order to make the temperature and concentration of the anodizing bath liquid uniform, immediately take away a lot of heat near the oxide film, and avoid the phenomenon that the continuous accumulation of temperature is likely to cause the phenomenon of oxide film pulverization. Generally, the bath liquid is stirred during the anodization process.

(6)陽極氧化時間 (6) Anodizing time

氧化時間的控制根據硫酸濃度、槽液溫度、電流密度、鋁材質、鋁工件對氧化膜厚度和性能的要求來決定。假設每條生產線各自的的操作溫度和槽液條件和預設的電流密度i是固定的,只需試驗將各材質的成膜係數K,然後依膜厚公式δ=K*Q=K*i*t,依膜厚δ推算所需陽極處理的時間。 The control of the oxidation time is determined according to the sulfuric acid concentration, the bath temperature, the current density, the aluminum material, and the requirements of the aluminum workpiece on the thickness and performance of the oxide film. Assuming that the respective operating temperature and bath conditions of each production line and the preset current density i are fixed, it is only necessary to test the film formation coefficient K of each material, and then according to the film thickness formula δ=K*Q=K*i *t, the required anodic treatment time is estimated according to the film thickness δ.

然而,先前電解液的分析方法都是採用滴定法,請配合參閱第3圖所示: However, the previous analysis methods for electrolytes were all based on titration, please refer to Figure 3 for details:

總酸濃度(g/L):取5ml電解液樣品放到250ml燒杯中,利用純水稀釋至150ml,利用磁石攪拌器攪拌,滴入5滴酚酞指示劑,用1(N)氫氧化鈉溶液滴定至溶液由無色變成粉紅色(pH值≒8)即為滴定終點,紀錄X(N)氫氧化鈉溶液的消耗量A(ml)。 Total acid concentration (g/L): Take 5ml of electrolyte sample into a 250ml beaker, dilute to 150ml with pure water, stir with a magnetic stirrer, drop 5 drops of phenolphthalein indicator, use 1(N) sodium hydroxide solution Titrate until the solution changes from colorless to pink (pH value≒8), which is the end point of the titration, and record the consumption A (ml) of X(N) sodium hydroxide solution.

總酸濃度(g/L)=9.8*A*X Total acid concentration (g/L)=9.8*A*X

游離酸濃度(g/L)、鋁離子濃度(g/L):取5ml電解液樣品放到250ml燒杯中,利用純水稀釋至150ml,利用磁石攪拌器攪拌,滴入5滴酚酞指示劑,加入2g氟化鉀(KF),用1(N)氫氧化鈉溶液滴定至溶液由無色變成粉紅色(pH值≒8)即為滴定終點,,紀錄X(N)氫氧化鈉溶液的消耗量B(ml)。 Free acid concentration (g/L), aluminum ion concentration (g/L): Take 5ml of electrolyte sample into a 250ml beaker, dilute to 150ml with pure water, stir with a magnetic stirrer, drop 5 drops of phenolphthalein indicator, Add 2g potassium fluoride (KF), titrate with 1(N) sodium hydroxide solution until the solution changes from colorless to pink (pH value≒8) is the titration end point, record the consumption of X(N) sodium hydroxide solution B (ml).

游離硫酸濃度(g/L)=9.8*B*X Free sulfuric acid concentration (g/L)=9.8*B*X

鋁離子濃度(g/L)=1.8*(A-B)*X Aluminum ion concentration (g/L)=1.8*(A-B)*X

於是,先前的滴定方法,需要較多的時間、設備、以及藥劑費用,人員操作過程容易有取樣誤差還有滴定終點的判斷誤差,造成分析結果的落差,而且無法運用到線上監控。 Therefore, the previous titration method requires more time, equipment, and pharmaceutical costs, and the personnel operation process is prone to sampling errors and judgment errors of the titration end point, resulting in a gap in the analysis results, and it cannot be applied to online monitoring.

有鑑於此,本發明人於多年從事相關產品之製造開發與設計經驗,針對上述之目標,詳加設計與審慎評估後,終得一確具實用性之本發明。 In view of this, the inventor of the present invention has been engaged in the manufacture, development and design of related products for many years, aiming at the above-mentioned goals, after detailed design and careful evaluation, finally came up with a practical invention.

When the concentration of free sulfuric acid is within the set standard, it can be directly produced and sampled regularly for calculation; on the contrary, when the concentration of free sulfuric acid is insufficient or too high, the concentration of sulfuric acid needs to be re-adjusted and sampled again. The values of conductivity, temperature and specific gravity in the electrolytic bath liquid are calculated and analyzed through the calculation framework, so that the free sulfuric acid concentration, total acid concentration and aluminum ion concentration in the electrolytic bath liquid can reach the set range, so as to be able to quickly and accurately Determine the composition of sulfuric acid electrolyte to prevent artificial problems from causing differences in analysis results.

本發明係提出以導電度、溫度、比重三個物理參數直接分析硫酸電解液的成分:游離硫酸濃度(g/L)、總酸濃度(g/L)、鋁離子濃度(g/L)。計算架構如下: The present invention proposes to directly analyze the composition of sulfuric acid electrolyte by three physical parameters of conductivity, temperature and specific gravity: free sulfuric acid concentration (g/L), total acid concentration (g/L), aluminum ion concentration (g/L). The computing architecture is as follows:

When the concentration of free sulfuric acid is added to the electrolytic cell, the concentration of free sulfuric acid is increased, so that the concentration of free sulfuric acid reaches the set range; on the contrary, if the concentration of free sulfuric acid and aluminum ion is too high, replace the electrolytic cell solution. , and reconfigure the ratio of sulfuric acid and pure water to make the concentration of free sulfuric acid and aluminum ion reach the set range.

較佳地,該分析系統係於該電解槽建立一自動取樣機,該自動取樣機內建導電度計、溫度計以及比重計,利用遠端線上操控方式操作該自動取樣機取得該電解槽液中的導電度、溫度以及比重參數,再將參數套入該計算架構內進行計算分析,俾能求得游離硫酸濃度、總酸濃度以及鋁離子濃度者,達到線上取樣監控的效果,省下人工取樣的時間;又該分析系統係於該電解槽更搭配有硫酸自動加藥機以及鋁離子分離酸回收系統,當經該計算架構計算出游離硫酸濃度不足時,俾能經由該硫酸自動加藥機將硫酸添加至該電解槽內;此外,當經該計算架構分析出游離硫酸濃度及鋁離子濃度太高時,則能經由該鋁離子分離酸回收系統將硫酸回收,並穩定鋁離子濃度者。 Preferably, the analysis system is to establish an automatic sampling machine in the electrolytic cell, and the automatic sampling machine has built-in conductivity meter, thermometer and hydrometer.

為使 貴審查委員對本發明之目的、特徵及功效能夠有更進一步之瞭解與認識,以下茲請配合【圖式簡單說明】詳述如後: In order to enable your examiners to have a further understanding and understanding of the purpose, features and effects of the present invention, please describe in detail as follows in conjunction with [Brief Description of Drawings]:

首先,先請參閱第1圖所示,一種鋁合金陽極處理硫酸電解液分析系統,係應用在分析電解槽液的成分濃度,包含一導電度計、一溫度計以及一比重計,用以量測電解槽液中的導電度、溫度以及比重等物理參數,再將上述所測得之導電度(CS-A-T(mS/cm))、溫度(T(℃))、比重(DS-A-T(g/ml))經由一計算架構進行計算分析,以取得電解槽液中之游離硫酸濃度(g/L)、總酸濃度(g/L)以及鋁離子濃度(g/L),經該計算架構所計算出的數據再依據電解槽液所需游離硫酸濃度、總酸濃度以及鋁離子濃度的設定標準判定濃度是否充足。 First of all, please refer to Figure 1, an aluminum alloy anode treatment sulfuric acid electrolyte analysis system, which is applied to analyze the component concentration of the electrolytic bath liquid, including a conductivity meter, a thermometer and a hydrometer for measuring The physical parameters such as conductivity, temperature and specific gravity in the electrolytic bath solution, and then the conductivity (C SAT (mS/cm)), temperature (T (°C)), specific gravity (D SAT (g/ml) measured above )) is calculated and analyzed through a calculation framework to obtain the free sulfuric acid concentration (g/L), the total acid concentration (g/L) and the aluminum ion concentration (g/L) in the electrolytic bath solution, which are calculated by the calculation framework The obtained data is then used to determine whether the concentration is sufficient according to the set standards of free sulfuric acid concentration, total acid concentration and aluminum ion concentration required by the electrolytic bath solution.

以導電度、溫度、比重三個物理參數直接分析硫酸電解液的成分:游離硫酸濃度(g/L)、總酸濃度(g/L)、鋁離子濃度(g/L)。計算架構如下: The composition of sulfuric acid electrolyte is directly analyzed by three physical parameters of conductivity, temperature and specific gravity: free sulfuric acid concentration (g/L), total acid concentration (g/L), aluminum ion concentration (g/L). The computing architecture is as follows:

其分析系統之運作流程實施例,再請參閱第1圖所示,導電度、溫度、比重取樣時係依序利用該導電度計、溫度計以及比重計從該電解槽取樣,將取樣之數據經計算架構計算分析後,當電解槽液中的成分游 離硫酸濃度、總酸濃度以及鋁離子濃度在設定範圍內時,即可直接進行電解成膜作業,並定時取樣進行計算分析;反之,當取樣之數據經計算架構計算分析後呈現游離硫酸濃度不足之情況時,俾再將硫酸添加至電解槽中,以達到游離硫酸濃度設定的範圍;此外,當取樣之數據經計算架構計算分析後呈現游離硫酸濃度及鋁離子濃度太高的情況時,則必須抽換電解槽液,並重新調配硫酸與純水的比例,以符合游離硫酸濃度以及鋁離子濃度所設定之濃度範圍。 An example of the operation flow of its analysis system, please refer to Figure 1 again. When sampling conductivity, temperature and specific gravity, the conductivity meter, thermometer and hydrometer are used to sample from the electrolytic cell in sequence. Computational Architecture After calculation and analysis, when the components in the electrolytic bath When the sulfuric acid concentration, total acid concentration and aluminum ion concentration are within the set range, the electrolytic film formation operation can be carried out directly, and sampling is carried out regularly for calculation and analysis; on the contrary, when the sampled data is calculated and analyzed by the calculation framework, the free sulfuric acid concentration is insufficient.
