The article "On Several Current Generation Methods of Slightly Acidic Hypochlorous Acid Water" was eventually published in three parts. During this period, we received calls and letters from teachers, scholars, users, colleagues and other friends. Thank you for your support and encouragement! Thank you for your corrections and instructions! Due to the limited word count for the published articles, many errors have not been corrected. We apologize for any inconvenience. Many friends said: Most of the content in the article was exchanged when they met before, and they didn't feel it deeply at that time. But after using the Fangxin equipment for a while and reading this article again, they found that they had a systematic understanding and new experience of the generation method of slightly acidic hypochlorous acid water. Everyone also raised some detailed issues they encountered during the usage process one after another for communication. Here, some representative questions are selected and answered collectively as follows: Question: Which generation method has a better sterilization effect? Answer: Firstly, regarding the sterilization effect of these methods, when using them specifically, you can check the third-party test report provided by the supplier. Secondly, in terms of the composition of the products, although the main content of the bactericidal component is hypochlorous acid, different generation methods may also produce oxides of different contents (which also have bactericidal properties). Some people think that containing multiple bactericidal components might make the sterilization more comprehensive. Some people also believe that when the antibacterial components are complex and directly used for food disinfection, they may react with certain components in the food, posing a food safety risk. Ultimately, whether it is the sterilization effect or food safety, it depends on whether the content values of specific substance components meet the relevant standards? As long as the content value of the product is within the standard range, it is qualified and safe. So, "Which generation method has a better sterilization effect after all?" I really can't answer this question. In the field of disinfection, I'm also a student. More experience and data are needed from teachers, experts, scholars and experienced people in this field.

2. Q: Why does my device consume more hydrochloric acid than the "over 100 grams of HCl" mentioned in the text? Answer: The Cl- conversion rate of this method is particularly high. Basically, it consumes over 100 grams of HCl to generate 1 ton of slightly acidic hypochlorous acid water with an effective chlorine concentration of 100 PPM. In some countries around the world, concentrated hydrochloric acid contains 36%HCl, while in others it contains 32%HCl. There are both 6%HCl and 3%HCl when using dilute hydrochloric acid. The "HCl" in my text refers to 100% HCl. Multiply the amount of hydrochloric acid consumed by the equipment by the actual concentration of hydrochloric acid. The actual consumption is consistent with the value in the text, and there is no difference. Our electrolytic conversion rate is very high, and it can usually be approximately calculated at a 100% conversion rate.   3. Q: Why is the effective chlorine content in my hypochlorous acid water qualified, but the chloride ion level is low? Answer: The original text [(3) How to prepare slightly acidic hypochlorous acid water with high concentration of available chlorine?] The effective chlorine detector is used to measure the concentration of chloride ions with a valence of 0 and above, while the chloride ion detector is used to measure the concentration of chloride ions with a valence of -1. The process of generating hypochlorous acid water is to convert the negative one-valent chloride ions into positive one-valent chloride ions. Therefore, under the condition of the same effective chlorine content, the lower the concentration of negative one-valent chloride ions in slightly acidic hypochlorous acid water, the better. A lower concentration indicates a higher conversion rate, lower residue, and no corrosion, suggesting that the electrolysis technology and process are better. Please refer to the self-test data of the slightly acidic hypochlorous acid water produced by the customer:

Effective chlorine content: 112mg/L

【 Concentration of negative one-valent chloride ions 27ppm】

Here, I would like to express my special gratitude to "Meticulous care, coming for beauty!" The self-inspection pictures provided by Abacho Medical Technology Co., Ltd. are welcome for everyone to extend and read [Abacho Initiates a 'Green Disinfection' Technology Revolution to Produce Long-lasting 'Green Disinfection' Products]. Readers are also welcome to test the relevant data of its self-produced slightly acidic hypochlorous acid water. Let's analyze and exchange together.   Note: The detection picture shows the brand, model and reading of the detection instrument, which only indicates the authenticity of the data source.   Supplementary explanation: For the method of electrolyzing dilute hydrochloric acid, it is generally believed that the three indicators of available chlorine concentration, pH and chloride ion content are interrelated and interdependent (that is, when the available chlorine concentration increases, pH decreases and chloride ion content rises). The electrolysis technology and process of the Fangxin version (please keep it confidential and do not disclose it to those with information) have transformed these three indicators into independent parameters, which are controllable and adjustable.   4. Q: How does Fangxin achieve the stability of slightly acidic hypochlorous acid water? Answer: (5) How to solve the stability of available chlorine content in slightly acidic hypochlorous acid water? If slightly acidic hypochlorous acid water is prepared and used immediately, its validity period is sufficient. However, if it is a disinfectant for sale on the market, among all the testing indicators, there are usually concerns about the stability test, that is, whether the validity period can meet 12 months or more? There are many formulas and processes for achieving the stability of slightly acidic hypochlorous acid water. Our technical process is just one of them. We believe that the comprehensive indicators might be very good. There are also many factors affecting stability, and the testing cycle for each batch is quite long. In response to customer demands, we are still conducting some related experiments up to now. We also sincerely welcome everyone to visit, offer guidance and communicate.
