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(biāo)準(zhǔn)）/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(yáng)極）：氯化鉀1350kg/t（折百）；蒸汽7.5t/t；電耗2150kW·/t；綜合能耗2000kg標(biāo)準(zhǔn)/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(guò)兩者的對(duì)比，可以看出離子膜法產(chǎn)出的產(chǎn)品較隔膜法產(chǎn)品雜質(zhì)相對(duì)少、品質(zhì)高，成本價(jià)稍高，售價(jià)略高，隔膜法制作的產(chǎn)品略低，大家可根據(jù)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.
