The Production Process of Active Magnesium Oxide
Active magnesium oxide is mainly used in Rubber, Tyre, Adhesive, Convey Belt, Fluororubber, Magnetic Material, Medical Rubber Stopper and other industries. Hebei Meishen Chemical Technology Co.,LTD as the largest magnesium oxide production base in China, next we would like to tell us the production process of active magnesium oxide.
1.The formation of active magnesium oxide. In the process of magnesite calcination, due to technology, operators and other factors, the kiln temperature is different. When the temperature reaches 400-600 degrees, the internal structure of active magnesium oxide is loosened, the spaces between the crystals is the most, at this time, the activity of magnesium oxide present the highest.
2. When the temperature reaches 400-600 degrees, the activity is medium. The spaces between the crystals is becoming smaller, which reaches the best range of magnesium cement reaction. And when the temperature reaches or greater than 900-1000 degrees, it will form a burned magnesia, the activity is very low even none. Within a certain range, the higher of the activity, the better of the quality. But it is not suitable for subcooling magnesium oxide, when it has higher activity, the reaction is more intense, lead to the finished product poor quality, easily breakage and lower strength.
3. Active magnesium oxide, in other words, is the magnesium oxide with hydration ability.

The Production of Active Magnesium Oxide
Active magnesium oxide is a very important kind of chemical materials, except to being used as fire retardant, but also it has other widely usages. Now we will introduce the production methods of high active magnesium oxide.
This process has the characteristics of short circulation, easy operation and low cost, then what you get has high activity. Meanwhile pay attention to some problems.
1.Holding time and calcination temperature are the main factors influencing activity. With the extension of heat preservation time and the increases of calcination temperature, magnesium oxide crystal shape is becoming more and more complete. Translate metastable amorphous into closely, complete crystal crystal structure, the activity gradually lower.
2.In order to get active magnesium oxide, you should control reasonably the time of sample inside furnace. The key to get high active magnesium oxide is that controlling heat preservation time and calcination temperature to ensure complete decomposition of magnesium hydroxide and restrain the growth of the magnesium oxide crystals.
3.The microstructure of magnesium oxide has a big influence on its macroscopic properties.

Some Important Characteristics of Magnesium Oxide in Silicon Steel Sheet
1.The activity of magnesium oxide
In order to improve the response capacity of MgO and SiO2, magnesium oxide must have the activity. Nano magnesium oxide have the greatest activity, so use it can improve the production of silicon steel.
2.The particle structure of magnesium oxide
In order to improve the bulk density of the surface of silicon steel sheet, the particle structure must tend to approximate spherical, because the ball has the advantage of close packing. Magnesium oxide used in the surface of silicon steel sheet can play a good role.
3.Particle size distribution of magnesium oxide
Magnesium oxide serous is smeared on silicon steel sheet, then after drying it will curled up into tubular. In the process, magnesium oxide is required of good permeability.
Different magnesium oxide have different influence in silicon steel sheet production. You had better choose the suit type for you. More information, you can consult us.

High active magnesium oxide for Fluororubber
Active magnesium oxide plays the role of acid absorption in fluororubber production, for the purpose of speeding up the sulfide. The second, magnesium oxide can increase the bonding performance with metal skeleton, heat-resistant quality and so on. Inhale iodine value is the key to judge the performance of magnesium oxide in acid absorption. Under normal circumstances, the larger Inhale iodine value, the stronger ability of acid absorption. For example, when used as acid acceptor, you only add three copies of high active magnesium oxide is OK, but if you add lower active magnesium oxide, you need add five copies, even more.
Magnesium oxide and zinc oxide are common used as acid acceptor. When adding zinc oxide, usually used same amount of dibasic lead phosphite in water resistance rubber. While magnesium oxide is used in high heat resistance rubber. Lead oxide is often used in acidproof rubber. Calcium oxide, or together with magnesium oxide is used as low compression and deformation rubber. Calcium hydroxide and active magnesium oxide are the main acid-acceptor.
The more applications of active magnesium oxide, you can consult our online customer service or send a massage to our email. We will reply for you as soon as possible.

Magnesium Oxide for Glass Fiber Reinforced Plastic
Hebei Meishen Chemical Technology Co.,LTD is professional in manufacturing different specifications magnesium oxide, which is suitable for all kinds of industries, like Tyre, Wire, Catalyst, Plate Glass, Silicon Steel, Rubber, Adhesive and other production. We have rich production experience and technology guidance.
Next we will introduce Magnesium Oxide for Glass Fiber Reinforced Plastic. It is a white amorphous powder, MgO≥95%, CaO≤1.5%, Iodine adsorption value 80~120mgI2/gMgO. Its plays an important role in thickening agent, curing time modifier, strengthen the brightening agent. Generally speaking, active magnesium oxide is the best choice for producing Glass Fiber Reinforced Plastic products. It's worth noting that we need adjust the content of magnesium oxide with the changes of climate. If the activity is high, FRP thickening is faster; otherwise if the activity is low, glass fiber reinforced plastic sheet will become soft, so that it is not easy to dry. In fact, the need of activity is higher in winter than summer.
