氫氧化鉀是常用的化工原料和化工助劑，可以分為食品級、醫藥級、工業級，根據行業不同的需求而制作相應的產品。目前，氫氧化鉀的制作方法有兩種工藝，一是隔膜法（金屬陽極），二是離子膜法，由于深沉工藝差別，產品質量有一定的差異，而所用原料的消耗也有所區別，本文對各制作工藝中所用原料以及產品消耗進行了粗略統計，以便對兩種方法有清洗的對比。
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、離子膜法：氯化鉀1350kg/t（折百）；蒸汽2t/t；電耗2000kW·/t；綜合能耗1300kg（標準）/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（金屬陽極）：氯化鉀1350kg/t（折百）；蒸汽7.5t/t；電耗2150kW·/t；綜合能耗2000kg標準/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.
通過兩者的對比，可以看出離子膜法產出的產品較隔膜法產品雜質相對少、品質高，成本價稍高，售價略高，隔膜法制作的產品略低，大家可根據自身的需求選擇。
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.
