Liaoning Longmagnesium Technology Co., Ltd. Activated magnesium oxide is a functional inorganic material developed in recent years, which can have different uses based on its activity level. Active magnesium oxide can be divided into high activity, active, and low activity magnesium oxide based on its iodine absorption value. High active magnesium oxide is mainly used for medical Butyl rubber bottle stopper, medium active magnesium oxide is mostly used for neoprene, and low active magnesium oxide is mostly used for acid wastewater treatment, flue gas desulfurization, etc.
With the upgrading of industrialization and the demand and development of the technical functional material market, a series of fine magnesium oxide products have been developed and produced, mainly used for nearly ten varieties, including advanced lubricating oil, advanced tanning alkali grade, food grade, pharmaceutical, silicon steel grade, advanced electromagnetic grade, and high-purity magnesium oxide.
For laypeople, how to measure the related activity of magnesium oxide? Adhesive specific magnesium oxide mesh gives us some steps:
1. In the inventory of magnesium oxide, take 100 grams of magnesium oxide samples from different corners and positions (not less than 3 places), and mix them evenly.
2. Accurately weigh 100g of magnesium oxide powder from the mixed powder and place it in a constant weight dry beaker. Add 400g of pure water to make it completely wet.
3. Place the cup in a drying oven with a set temperature (110 ℃) and let it dry for more than 2 hours. Then, adjust the oven to 150 ℃ and dry the sample to constant weight. Activity calculation method: The activity content of magnesium oxide is [(W-100)/45] X 100%, where 100 is the weight of the sample before hydration; W is the weight of the sample after hydration;
Magnesium oxide has high activity, light weight and looseness, and is widely used in flame retardants and medicine. It is one of the functional materials with promising development prospects. Light burned magnesium oxide is a widely used product with a high yield of inorganic substances. According to their uses, they are mainly divided into several categories: fused magnesium oxide, industrial magnesium oxide, heavy magnesium oxide, friction material specific magnesium oxide, pharmaceutical magnesium oxide, and metallurgical magnesia. Its magnesium oxide content greater than 99.0% is referred to as high-purity magnesium oxide. So, what are the advantages and gaps in China's magnesium oxide production? Light burned magnesium oxide
After investigating the reasons for the price increase this time, some analysts believe that the environmental shutdown of many magnesium oxide manufacturers has become the direct cause of product price increases, but the most fundamental reason is weak demand. Nearly 60% of domestic magnesium oxide products are used in the tire market. Due to the continuous regulation of the rubber market by the government, the tire market has also been affected, becoming the main cause of weak demand for magnesium oxide. In addition, the weak macroeconomic recovery pattern has not provided strong support for the demand side. It is expected that if driven by Magnesia, the industry's price increase trend will continue, and more and more small and medium-sized manufacturers will stop production or even exit the industry. 1. The large center air-cooled composite burner for light burned magnesium powder is composed of a heat-resistant steel air-cooled framework and refractory materials, which is resistant to high temperature, wear resistance, long service life, and a combustion power of 5-15GJ/h. Provides a powerful central flame for the center of the roasting zone. The problems of insufficient central air flow, uneven temperature distribution, central burning and edge over burning of lime kiln (lime kiln) are solved. The increase in production and quality of TGS lime kiln (lime kiln) is conducive to the large-scale production of lime kiln (lime kiln). It can provide stable and high-quality activated lime (lime) for steelmaking.
