Everyone subconsciously believes that all chemical raw materials are toxic, so many people will want to stay away as long as they come into contact with chemical materials. So is magnesium oxide harmful to the body? Liaoning Magnesium Oxide
Put the cup in a drying oven with adjusted temperature (110°C) and bake for more than 2 hours, and then adjust the oven to 150°C to dry the sample to a constant weight.
Activity calculation method: active content of magnesium oxide=【(W—100)/45】X100%
In the formula, 100 is the weight of the sample before hydration; W is the weight of the sample after hydration; 45 is the conversion factor.
Note: In order to obtain a more accurate value, you can take 3 copies of 100g magnesium oxide assay, add the obtained active content value, and divide by 3.
[Daily chemicals]: facial cleanser, beauty cream, lotion, shampoo, toothpaste, shower gel, facial mask, etc.
[Feed veterinary medicine]: canned pets, animal feed, nutrient feed, genetically modified feed research and development, aquatic feed, vitamin feed, veterinary drug products, etc.
[Experimental reagents]: Can be used for various experimental research and development, etc.
Magnesium oxide has a very wide range of uses. Light burned magnesium powder can be used in areas such as special magnesium oxide for tires, special magnesium oxide for medical rubber stoppers, and magnesium oxide nets for adhesives. Therefore, magnesium oxide is more than a ton for its special oxidation in tires. We may not be very familiar with some specific uses of magnesium. Here I will introduce you to it: light burnt magnesia powder
1. Function: It acts as scorch inhibitor, vulcanization accelerator, acid absorbent (halogenated butyl rubber will release hydrogen chloride during the vulcanization process), filler, high temperature resistance, fire retardant, abrasion resistance, and corrosion resistance.
2. Requirements for magnesium oxide: MgO≥92%, CaO≤1.5%, apparent specific volume between 4.5-5.5ml/g, hydrochloric acid insoluble matter ≤0.2%, sieve residue ≤0.01%, moisture content ≤0.5%, Water-soluble matter ≤1.0%, loss on ignition ≤5.0%; (magnesium oxide has a certain activity which is beneficial to improve product quality, and can extend the scorch time and improve the flexibility and wear resistance of the product).
The main purpose of the product: Light burnt magnesia ball is a new type of converter steelmaking slagging material made of light burnt magnesia powder as raw material and pressed into balls. The light-burned magnesia ball is mainly used as the slag protection component regulator of the converter slag splash protection. Because of slag splash protection
The furnace requires the slag to have suitable viscosity and refractoriness.
