What’s the Difference Between Industrial Grade MgO and Pharma Grade MgO?

   The industrial grade MgO is a kind of industrial raw material. According to the different products, the magnesium oxide has different contents. In industry, Meishen Technology has special industrial grade magnesium oxide. For the food grade magnesium oxide and pharmaceutical grade magnesium oxide, it also has special content and character. However, many people still do not know the difference between industrial grade MgO and Pharma grade MgO. So, let’s talk about it.

   The magnesium oxide produced by Hebei Meishen Technology Co., Ltd has passed the GMP certification. The executive standard is Chinese Pharmacopoeia(CP2010). It is special magnesium oxide used for medicine. The appearance of it is white powder. What’s more, it can neutralize alkalescence and increase magnesium ion content. In medicine, it is used as antacid and laxative to treat hyperacidity, the stomach and duodenum ulcer. In addition, it can used in medical stopper industry. In general case, the light and active magnesium oxide both can be used.

   It is relatively complex for the industrial grade magnesium oxide. Because the magnesium oxide has many applications in industry. The executive standard of special magnesium oxide used for adhesive is HG/T3928-2007HG/T2573-2006. It is also white powder. In adhesive, it can be used as scorch retarder, vulcanizer and acid-acceptor. According to the different requirements of fitness, activity, heavy metal, black-and-white points, mechanical impurity, clarify, tensile strength, curing speed, resistance to elevated temperatures, discoloration and sediment and scorch safety, it can adjust all times.

   Through the above description, you should know the differences between the two in the rough. As a matter of fact, there are a lot of knowledge about magnesium oxide. Therefore, many people still didn’t know it clearly. You can directly contact with customer service of Meishen Technology. It is a professional magnesium oxide manufacturer. Or you can visit this company. It is better to communicate. 

Why to Test Magnesium Oxide’s Active?

According to the characteristics, magnesium oxide can be divided into active magnesium oxide and light magnesium oxide. For the magnesium oxide’s activity, is it need to be tested? Does the different active lead different materials? As a professional magnesium oxide manufacturer, we can say yes. Therefore, it is necessary to test magnesium oxide. Now, let’s talk about the detail:

1. After purchasing magnesium oxide, you should think about the store patterns. Affected by storage condition and environment humidity, the magnesium oxide is very reactive with the water in the air and carbon dioxide. The activity will be decreased gradually. The longer store time, the worse condition of losing the activity.

Therefore, in order to assure magnesium products’ quality, you should match the scientific molar ratio according to the magnesium oxide’s actual active content. In addition, you should adjust formula in time.

1. The the magnesium ore have different calcination temperature of ore grade, calcining technology and talcum powder. So the magnesium oxide have different active content. During the working process of magnesium products, only the active magnesium oxide participates in a reaction.

How to Detect Magnesium Oxide in Magnesium Hydroxide?

   The testing result of magnesium oxide is always constrained by many factors. Sometimes it has higher error.　　

   1. You should master environment temperature in the different seasons. The test environment temperature has great influence on test data, especially the difference in winter. Therefore, in order to effect solution concentration and titration speed, you should control indoor temperature strictly.  

   2. The measure of titration end point is accurate. The speed near to end point of titration must be slow. In order to make sure the end point is accurate, you should carefully observe the changeable indicator color.

   3. The timing and calibration about concentration of the standard solution. You should use zinc oxide to benchmark solution concentration with EDTA. The concentration of solution is 4. And it should according to the standard of Ministry of Chemical Industry.

The Special Magnesium Oxide Used in Cable

   The magnesium insulation cable is a kind of new cable with seamless copper tube outer layer. The centrality is filled with magnesium oxide powder, and the conductor is sub-thread copper rod. It has many advantages, such as high temperature resistance, fireproofing, anti-explosion, inflaming retarding, small outside diameter, high mechanical strength, long life and need not independent earth lead. Therefore, magnesium insulation cable has been widely applied in the environment with risk, scurviness and high temperature, for example, nuclear power station, metallurgy, chemical engineering, mine, etc. Over the years, with the flourish of different skills and crafts, the magnesium oxide cable is also used in civil architecture, like high-rise buildings, airport, wharf, underground and so on.

The advantage of magnesium insulation cable

   1. Preventing fires thoroughly.

   The magnesium insulation cable is nonflammable. When the temperature achieves 250℃, it can operate for a long time. When the temperature achieves 1000℃, it also can insist to operate normally for 30 minutes. Therefore, it won’t bring fire. Even in the case with fire, the magnesium insulation cable need not to change if flame temperature is lower than melting point temperature of copper. In addition, in the case of fire, it won’t create toxic fumes and gases.

   2. Strong ability of overload protection

   When the circuit overload, the cable won’t be damaged as long as the heat can not achieve copper’s melting point. Even if it is punctured at moment, the magnesium oxide crystal won’t form carbides. After the overload eliminates, the functions of cable would not change and operate normally.

   3. High operating temperature

   Because the melting point temperature of magnesium oxide crystal in insulating layer is higher than the melting point temperature of copper. Therefore, for the cable, the highest temperature of long operation can achieve 250℃. In the short term, it can operate regularly at nearly cooper’s melting temperature.

   4. Good explosion-proof function and antisepsis function

   Due to the protecting bush is solid drawn steel pipe, magnesium oxide cable has many functions, such as prevent water, inoisture, oil and the damage of chemicals. In addition, the copper pipe has proper mechanical strength. So it has a better explosion-proof function.

   5. Long life

   The magnesium insulation cable is composed of inorganic data. So there can be no question on insulation aging. Its using life is more than three times as much to general cable.

   6. Higher flexibility

   As a magnesium oxide supplier, we can tell you the magnesium insulation cable can be set on crane span structure with general cable. It is always more flexible than general cable laying and saves the investment of cable bridge. In this way, it drops project cost as well.

Magnesium Oxide Used in Adhesive

   The active magnesium oxide is one of the important raw material of chloroprene rubber adhesive agent. The activity of magnesium oxide reflects the reaction capacity between magnesium oxide and chloroprene rubber adhesive agent. The activity of active magnesium oxide is usually presented by iodine absorption value(mgT2lg). It is low activity when the iodine absorption value is lower than 40(mgIz/g). The middle activity is between 40 to 100 of the iodine absorption value. When the iodine absorption value is higher than I0, it is the high activity. Generally speaking, the high quality neoprene adhesive needs magnesium oxide with high activity.

   The polychloroprene adhesive is an important type in fluoro rubber adhesive with large production and extensive use. It has many advantages, such as large initial adhesion, high bonding strength, flexible adhesive layer and good elasticity. What’s more, it has impact resistance, water resistance, oil resistivity, alkali resistance, acid resistance and solvent resistance. Of course, it has good anti-ozone, ageing resistant, durability and fire resistance. Therefore, it can bond many metal material and non-metallic material. For example, it can be used to bond rubber, leather, fabric, artificial leather, wood, beton, asbestos and so on. It is especially appropriate for the bonding between above materials and different materials like metal, plastic and so on. In addition, it has three types. There are solvent type, emulsion type and non-solvent type. Among the three, the solvent type of chloroprene rubber adhesive agent has the widest applications. And the he solvent type of chloroprene rubber adhesive agent can be divided into heat curing type and cold bonding type. At present, the most widely-used neoprene adhesive is solvent and cold bonding type adhesive.
