氢氧化钾现在被广泛的进行使用，在产品的制造方法中，有一种叫做隔膜电解的方法。那么隔膜法氢氧化钾浓度是多少？该方法的制造步骤和该方法制造出来的成品又可以应用于哪些方面？以下就由小编来为大家详细的解释一下吧:

Potassium hydroxide is now widely used. Among the manufacturing methods of products, there is a method called diaphragm electrolysis. What is the concentration of potassium hydroxide in diaphragm method? What are the manufacturing steps of the method and the finished products produced by the method? The following is a detailed explanation by the editor:

隔膜法所得氢氧化钾浓度为10%～11%，需通过蒸发浓缩和冷却澄清，制得含45%～50%氢氧化钾溶液;也可继续在熬碱锅中浓缩，经脱色，制得固体氢氧化钾，或经制片成片状氢氧化钾产品。

The concentration of potassium hydroxide obtained by diaphragm method is 10%~11%, which needs to be concentrated by evaporation and clarified by cooling to prepare potassium hydroxide solution containing 45%~50%; It can also be concentrated in the alkali boiling pot and decolorized to obtain solid potassium hydroxide or flaked potassium hydroxide products.

隔膜电解法的原料氯化钾在化盐槽中溶解成饱和溶液。当加热到90℃的时候，单独加入碳酸钾，苛性钾，氯化钡除钙，镁和硫酸盐等杂质。经过沉淀然后去渣。用盐酸中和。将280~315g/l氯化钾溶液预热70~75℃,然后电解得到氢氧化钾。

The raw potassium chloride of diaphragm electrolysis is dissolved into a saturated solution in the salt dissolving tank. When heated to 90 ℃, potassium carbonate, caustic potash and barium chloride are added separately to remove impurities such as calcium, magnesium and sulfate. After sedimentation, the slag is removed. Neutralize with hydrochloric acid. Preheat 280~315 g/l potassium chloride solution to 70~75 ℃, and then electrolyze to obtain potassium hydroxide.

含量分析：

Content analysis:

精确称取试样约1.5g，溶于40mL新煮沸并冷却后的水中，冷15℃，加酚酞试液（TS-167）数滴，用1mol/L硫酸滴定。在粉红色消失时，记录所耗的酸量，加甲基橙试液（TS-148）数滴，继续滴定呈现持续不褪的粉红色。记录滴定所需酸的总体积。每1mol/L硫酸相当于总碱量（以KOH计）56.11mg。

Accurately weigh about 1.5g of the sample, dissolve it in 40mL of newly boiled and cooled water, cool it to 15 ℃, add several drops of phenolphthalein test solution (TS-167), and titrate it with 1mol/L sulfuric acid. When the pink color disappears, record the amount of acid consumed, add a few drops of methyl orange test solution (TS-148), and continue titrating until a persistent pink color appears. Record the total volume of acid required for titration. Each 1mol/L of sulfuric acid is equivalent to 56.11mg of total alkali (calculated by KOH).

氢氧化钾隔膜法得到的产品浓度是百分之十到百分之十一，需要蒸发浓缩且冷却澄清。配制含百分之四十五到五十的产品溶液；也可以在碱煮锅中浓缩。经过脱色制备固体产品或者是压片成片状的产品。

The concentration of the product obtained by the potassium hydroxide diaphragm method is 10% to 11%, which requires evaporation, concentration and cooling for clarification. Prepare a product solution containing 45 to 50 percent; It can also be concentrated in an alkali boiler. After decolorization, solid products are prepared or pressed into sheets.
