Potassium hydroxide is widely used in the industry, because the effect is different, the concentration and dosage of potassium hydroxide are also greatly different. How to judge the concentration and dosage of potassium hydroxide under normal circumstances? Now with xiaobian together to understand it!
Solids should be dissolved to 10% concentration before use （gas mixture or mechanical mixture can be used for dissolution）。 Dosage can be determined according to the turbidity of raw water, specific can be determined according to the pilot test. When potassium hydroxide is used in municipal or industrial sewage, the corresponding dosage and concentration are different.
In order to improve the treatment capacity, it is recommended to ensure dose and effectiveness by moving from small-scale trials to field trials. Mix solid potassium hydroxide （at room temperature） with water in a ratio of 1:3, dilute with 25-30 times water for about 30 minutes, and then operate in water.
Drinking water purification consumption is 1/100,000 of raw water, that is, the consumption of water per thousand tons （solid） is about 15 kilograms of potassium hydroxide. According to the turbidity and content of the water in this area, the amount can be found out through experiments. Do a little test before use to find out how much you need and then add.
Potassium hydroxide is not corrosive at room temperature, but can cause severe corrosion to many metals at high temperature and stress. Equipment and pipeline materials of different concentrations of sodium hydroxide solution at different temperatures are different, and the concentration of sodium hydroxide solution is 0~30%.
Equipment and piping made of a class of materials are generally resistant to corrosion if the temperature is below 50 ° C; However, 0%~30% naOH solution has better corrosion resistance to equipment and pipes made of secondary materials at 50~100℃。
In addition, if we blindly buy potassium hydroxide at a low price, it is difficult to choose a good product, even if we find some products hard to ensure that the quality can meet the requirements.
Therefore, when we choose potassium hydroxide as a high-value chemical, we should look for professional chemical companies to buy it. Professional chemical companies not only guarantee the quality of products, but also provide thoughtful services, such as sample testing, to help us choose the right products better on the way to purchase.
How to judge the concentration and dosage of potassium hydroxide? The above is the explanation of the problem. In addition, we have appropriately extended the relevant content of the product, so that we can better use it by knowing more about its professional knowledge. You can check it out at www.hnwlcs.com!
