Pickling corrosion inhibitor is a special chemical agent used in the pickling process of metal surfaces. Its main principle is to react with the metal surface in an acidic environment to form a protective film, thereby reducing the corrosion rate of the metal surface. The specific principle is as follows: Deoxygenation: Acid pickling corrosion inhibitors…

When using reverse osmosis scale inhibitors, it is usually necessary to follow the following steps: Determine appropriate dosage: Based on water quality analysis and specific reverse osmosis system requirements, determine the appropriate dosage of scale inhibitor. You can refer to the product description or consult a professional for advice. Preparation of scale inhibitor solution: Add…
Flocculants play an important role in wastewater treatment, helping to aggregate suspended particles into larger particles, thereby facilitating subsequent sedimentation and filtration. The following is the application process of flocculants in sewage treatment: Mixing and dosing: Flocculants usually exist in the form of powder or liquid. Firstly, it is necessary to mix the flocculant with…
For the preparation of fungicides, the following are some commonly used ingredients and methods: Bleaching powder (sodium hypochlorite): Bleaching powder is a common disinfectant and fungicide. It can be formulated into a solution for cleaning and disinfecting surfaces, equipment, and utensils. Pay attention to the correct dilution ratio and safety operation requirements when using. Alcohol:…
Reverse osmosis scale inhibitors and circulating water scale inhibitors are two different types of scale inhibitors, with some differences in application scenarios and mechanisms of action: Application scenario: Reverse osmosis scale inhibitor: mainly used in reverse osmosis (RO) systems for water quality treatment in processes such as seawater desalination and pure water preparation. It helps…
