The dry granulation process of pharmaceutical and food grade magnesium oxide refers to mixing magnesium oxide powder prepared by wet method with auxiliary agents such as binders, dispersants, lubricants, etc. under anhydrous or low-moisture conditions, and then granulating the powder through granulation equipment. A method of producing particles of a certain particle size and shape. […]

Technical field: The present invention relates to a process method for preparing high purity magnesium oxide, and in particular relates to a method for preparing high purity magnesium oxide with low chlorine root content. Background Technology: Magnesium oxide is an ionic compound, which is a white solid at room temperature, and high purity magnesium oxide

Magnesium oxide is generally divided into high-purity magnesium oxide and active magnesium oxide. Different models of magnesium oxide have different uses. Let’s take a look at the differences between high-purity magnesium oxide and active magnesium oxide. High-purity magnesium oxide generally refers to content greater than 98%. Under high-temperature conditions, high-purity magnesium oxide has good electrical

The main preparation processes for magnesium oxide for cover glass are as follows: 1. Magnesium hydroxide method: Using natural dolomite or magnesite as raw materials, magnesium hydroxide is obtained through calcination, digestion, filtration, drying, calcination and other processes, and then high-temperature melting, cooling, crushing, sieving and other processes are used to obtain magnesium hydroxide. magnesium.

Nano magnesium oxide is a material with broad-spectrum antibacterial activity and has the advantages of low toxicity, high heat resistance, and environmental friendliness. In recent years, research on the application of nano magnesium oxide in antibacterial materials has made great progress. Antibacterial mechanism of nano magnesium oxide The antibacterial mechanisms of nano magnesium oxide mainly

I. Overview Chlorinated polyethylene is a polymer material generated through chlorination substitution reaction in high-density polyethylene. It is a white powder, non-toxic and odorless. According to its structure and use, it can be divided into resin-type chlorinated polyethylene (CPE) and rubber-type chlorinated polyethylene (CM). 2. What key indicators should be paid attention to when adding
