氢氧化钾现在被广泛的进行使用，那么你对这个产品又了解了多少呢？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呢？
Potassium hydroxide is widely used now. How much do you know about this product? Among the manufacturing methods of products, there is a method called diaphragm electrolysis. What is the concentration of potassium hydroxide in the membrane process?
氢氧化钾一般采用两种工艺流程，一种是隔膜法(金属阳极)，另一种是离子膜法。虽然这两种工艺流程的流程基本相同，但有些细节差别很大。因此，为了准确地区分它们之间的差异，我们需要正确地掌握它们的过程的具体方法来确定质量差异。
Generally, two processes are adopted for potassium hydroxide, one is diaphragm method (metal anode) and the other is ion-exchange membrane method. Although the processes of these two processes are basically the same, some details are quite different. Therefore, in order to accurately distinguish the differences between them, we need to correctly grasp the specific methods of their processes to determine the quality differences.
隔膜电解(金属阳极)制备氢氧化钾的工艺流程简述如下：将满足电解需要的精制氯化钾水溶液连续注入金属阳极电解槽，用直流电电解产生阴极室流出物，经蒸发器蒸发浓缩得到液体产品，经连续浓缩、脱色、压片得到固体产品。
The process flow of diaphragm electrolysis (metal anode) to prepare potassium hydroxide is briefly described as follows: the refined potassium chloride aqueous solution meeting the electrolysis needs is continuously injected into the metal anode electrolytic cell, and the cathode chamber effluent is generated by direct current electrolysis. The liquid product is obtained by evaporation and concentration in the evaporator, and the solid product is obtained by continuous concentration, decolorization and tablet pressing.

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氯化钾溶液预热至70~75℃,然后电解得到氢氧化钾。
Potassium chloride, the raw material of the diaphragm electrolysis method, is dissolved into a saturated solution in the salt tank. When heated to 90 ℃, add potassium carbonate, caustic potassium and barium chloride separately to remove impurities such as calcium, magnesium and sulfate. After sedimentation, the slag is removed. Neutralized with hydrochloric acid. Preheat 280 ~ 315g / L potassium chloride solution to 70 ~ 75 ℃, and then electrolyze to obtain potassium hydroxide.
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。经过脱色制备固体产品或者是压片成片状的产品。
The concentration of potassium hydroxide obtained by the diaphragm method is 10% ~ 11%, and the solution containing 45% ~ 50% potassium hydroxide can be prepared by evaporation concentration and cooling clarification; It can also be concentrated in the alkali boiling pot and decolorized to produce solid potassium hydroxide or flaked potassium hydroxide. Solid products are prepared by decolorization or pressed into sheets.
