Hebei Messi Biology Co., Ltd. stated that nano magnesium oxide is a new type of functional fine inorganic material that has emerged with the development of nano material technology. Its particle size is between 1-1000nm. It is widely used in electronic ceramic materials, medicine, food, cosmetics, acid gas adsorbents, catalyst carriers and other fields, with broad application prospects and huge economic potential.
There are many methods for preparing nano powders internationally, and their classification standards are not uniform. They can be divided into wet and dry methods according to preparation conditions, granulation and crushing methods according to preparation processes, gas phase method, liquid phase method and solid phase method according to the aggregation state of the material, and chemical method and physical method according to whether the preparation process is accompanied by chemical reactions. At present, the reports on the preparation of nano magnesium oxide at home and abroad mainly include liquid phase precipitation method, sol-gel method, alcohol salt hydrolysis method, electrolysis method, gas phase method, solid phase method, etc.
Magnesium oxide and nano magnesium oxide are also used in rubber, feed, sunscreen cosmetics and other products. Nano magnesium oxide is a comprehensive upgrade of magnesium oxide, which has a great improvement on the products used after the upgrade. Everyone knows that there are three main aspects to measure the quality of magnesium oxide: 1. High specific surface area; 2. Small particle size; 3. High activity.
In the rubber field, especially in the production of radial tires and transparent rubber products, magnesium oxide is an excellent vulcanization activator. Large specific surface area and strong activity can significantly improve the thermal conductivity, wear resistance, tear resistance, tensile strength, smoothness and other indicators of the product, and if high-quality nano magnesium oxide is used, its dosage can be saved by 30-50%, greatly reducing the product cost. For the automobile tire manufacturing industry, high-quality nano magnesium oxide is undoubtedly a better choice.
Magnesium oxide is indispensable for sunscreen skin care products. The main purpose of sunscreen is to prevent ultraviolet rays from damaging the skin. The sunscreen strength of sunscreen skin care products is directly related to the particle size of magnesium oxide. The smaller the particle size of the material, the less damage to the skin caused by ultraviolet rays. At the same time, if the particle size of the material is too large, it will not be evenly spread on the skin, which will make the skin too white and unnatural, which is fatal to skin care products. Therefore, for cosmetics, we undoubtedly choose higher quality nano magnesium oxide!
