Talking about purchasing reactive magnesium oxide, as a professional magnesium oxide supplier and manufacturer, Meishen has something need to be mentioned. The activity we usually called is refers to the degree of reaction, while activity is determined by the thickness of magnesium oxide solid particles. Compared with ordinary magnesium oxide, the requirements for active magnesium oxide is different. For example, the appropriate particle size distribution, the average particle size:< 2 μm (2000nm); microscopic morphology is irregular particles or nearly spherical particles or crystal plate; the activity represent by citric acid (CAA) is 12~25s (the higher of the value, the lower active); the activity represent by absorbing iodine value is (80~120mgI2/100gMgO); specific surface area 5~20m3/g; apparent specific volume 6~8.5mL/g.
However in simple words, light magnesium oxide is belong to basic salts, the content of MgO plays an important role for activity. In general,high pure magnesium oxide are made by basic magnesium carbonate in long time of low temperature, special type furnace structure, energy consumption is higher, the finished product has large apparent specific volume, this is what to be noticed.
In China, industrial magnesium oxide roughly can be divided into active magnesium oxide and light magnesium oxide. About the application, active magnesium oxide is widely used in glass fiber reinforced plastic, fluorine rubber, medical rubber stopper, adhesives and other industries. In which, the adhesive industry mainly including neoprene adhesive, such as strongadhesive, contact glue, A90 neoprene glue, and common seen in the market of shoes material and decorative materials. What is more, there are some requirements for the activity of magnesium oxide. For example, the activity of magnesium oxide for glass fiber reinforced plastic≥60-120, the activity of magnesium oxide for fluorine rubber≥120-150, the activity of magnesium oxide for medical rubber stopper≥150, the activity of magnesium oxide for adhesive≥150. According to the different manufacturers, formula and production process, Meishen Technology can custom made the most suitable magnesium oxide kinds for you !
Meishen Technology is professional in producing various magnesium oxide, which can be used in many industries, such as food , medicine, silicon steel sheet, rubber products and so on. If you have any questions about magnesium oxide uses and the matters needing attention, you can consult us at any time. We will reply you within 24 hours.
