The shortcomings, problems and innovations of various generation methods In addition to the first method, Yantai Fangxin also offers the other four types of micro-acidic hypochlorous acid water generators. As long as the customer needs us, we will accept any customized requirements. While adhering to the unchanged manufacturing of four types of micro-acidic hypochlorous acid water generators, Fangxin has made innovative changes to some specific implementation processes and methods. Even though domestic and foreign experts generally believe that the stability of the effective chlorine content in micro-acidic hypochlorous acid water is poor and that it is produced and used on the spot, Fangxin has broken through this. 1) Fangxin's zero innovation and zero breakthrough in the sodium hypochlorite solution acidification method This kind of equipment has a low manufacturing cost and there was a certain demand in the past few years. However, the author believes that this approach is unlikely to yield breakthrough technologies. It is mostly about drawing on some similar implementation technologies from different industries and optimizing the generation process. It was not until a gathering that the author learned that a peer could come up with a grand and intimidating name for "a liquid-liquid mixing process". This is truly a highly technical job, making one realize that innovation in words is also a manifestation of a company's strength. To quote a golden saying by Bai Yansong: The Chinese language can be repeatedly "reinvented". Is there any character you don't recognize? No. But when she recombined the Chinese characters that we are all very familiar with, she created the artistic conception that "everyone has in their hearts but no one can write about it".   2) Fang Xin's innovation and breakthrough in the ion-exchange membrane method for the chlor-alkali industry This kind of equipment is extremely expensive. If the cost of the tank is not reduced, the equipment of this type is basically in high demand but in short supply. Apart from foreign countries, there is basically no domestic demand.
