氢氧化钾是常用的化工原料和化工助剂，可以分为食品级、医药级、工业级，根据行业不同的需求而制作相应的产品。目前，氢氧化钾的制作方法有两种工艺，一是隔膜法（金属阳极），二是离子膜法，由于深沉工艺差别，产品质量有一定的差异，而所用原料的消耗也有所区别，本文对各制作工艺中所用原料以及产品消耗进行了粗略统计，以便对两种方法有清洗的对比。
　　Potassium hydroxide is a common chemical raw material and chemical additive, which can be divided into food grade, pharmaceutical grade and industrial grade. According to different needs of the industry, corresponding products are made. At present, there are two methods to make potassium hydroxide, one is the diaphragm method (metal anode) and the other is the ion-exchange membrane method. Due to the difference of the deep-seated process, the product quality is different, and the consumption of raw materials is also different. In this paper, the consumption of raw materials and products used in each process is roughly counted, so as to have a comparison of the two methods.

　　1、离子膜法：氯化钾1350kg/t（折百）；蒸汽2t/t；电耗2000kW·/t；综合能耗1300kg（标准）/t。
　　1. Ion membrane method: potassium chloride 1350kg / T (converted into one hundred); steam 2T / T; power consumption 2000kW · / T; comprehensive energy consumption 1300kg (standard) / T.
　　2、隔膜法（金属阳极）：氯化钾1350kg/t（折百）；蒸汽7.5t/t；电耗2150kW·/t；综合能耗2000kg标准/t。
　　2. Diaphragm method (metal anode): potassium chloride 1350kg / T (100 fold); steam 7.5t/t; power consumption 2150kw · / T; comprehensive energy consumption 2000kg standard / T.
　　通过两者的对比，可以看出离子膜法产出的产品较隔膜法产品杂质相对少、品质高，成本价稍高，售价略高，隔膜法制作的产品略低，大家可根据自身的需求选择。
　　Through the comparison of the two methods, we can see that the products produced by the ion-exchange membrane method are relatively less impurities, high quality, slightly higher cost price, slightly higher price, and slightly lower products produced by the membrane method. You can choose according to your own needs.
