active magnesium oxide CAS NO.1309-48-4

There are six types of Active Magnesium Oxide(activity-150, activity -120, activity -80, activity -60

Active magnesium oxide has a fine grain size, high content, high activity, stability, quality and other characteristics, primary as butyl rubber, chloroprene rubber, styrene-butadiene rubber and fluorine rubber accelerator and activator.　

 

Active magnesium oxide, molecular formula MgO, relative molecular mass of 40.30. Its chemical composition, physical form and other indicators and common magnesia is not much difference, but some indicators of active magnesium oxide and magnesium oxide general requirements are different; like to have a suitable particle size distribution, mean particle size: <2 μm (2000nm); irregular particle morphology is nearly spherical granules or flakes or crystals; with citric acid (CAA value) marked activity of 12 ~ 25s (the smaller the value the higher activity); activity represented by iodine adsorption of 80 ~ 120 (mgI2/100gMgO); specific surface between 5 ~ 20m3 / g, depending on the specific volume 6 ~ 8.5mL / between g. Furthermore, due to the high activity of this magnesium oxide, readily absorbing water, chemical treatment may be required for protection. In some aspects exhibit special properties not available in conventional materials, so as a new material has been widely used.　　

 

Preparation of high active magnesium oxide is fine inorganic functional materials, electronic components, ink, harmful gas adsorbent important raw materials. Expected to develop cutting edge material for the harsh conditions of high temperature, high corrosion. May be used as paints, cosmetics, paper and packing, plastic and rubber fillers and reinforcing agents and auxiliary materials, electronic materials, etc.Hebei Meishen Chemical Technology Group Co.,Ltd is based on magnesia products , focus on the high-end magnesium salt industry development . Through the development of unremitting efforts for more than ten years,Meishen chemical group becomes the No.1 sales and market share in China,the world's top ten conglomerate companies in single product .
