Recently, a customer inquired about the magnesium oxide used in phenolic resin.
However, the customer is only a trader, so he does not know about the detailed information. Therefore, Hebei Meishen Technology Co., Ltd. takes this opportunity to tell you about the magnesium oxide used in phenolic resin and other related knowledge about magnesium oxide.
Magnesium oxide was added into phenolic resin and polymerized resin to catalyze and absorb acid.
A special coating for mechanical equipment is the use of magnesium oxide high temperature resistance properties to improve the shading rate and reflectivity of the coating. Requirements for magnesium oxide: MgO≥93%, CaO≤1.0%, apparent volume ≥ 7mL /g. Note: good whiteness, large volume easy to use. Polymer resin light and active magnesium oxide, light magnesium oxide: content is 93-95%, active magnesium oxide: content is 88-92%, suction 唺 value 120-150.
The more magnesium oxide used in the same particle, the greater the total interface between the two phases and the faster the reaction rate.
Similarly, with the same amount of magnesium oxide, the total interface of the two phases with large particles is smaller than that of the two phases with small particles. Therefore, although the dosage is the same, the reaction rate with small particles is good.
Hebei Meishen Technology Co., Ltd. is a high-tech private joint-stock enterprise, specializing in the development and production of magnesium oxide.
At present, we mainly have three series of magnesium oxide, magnesium carbonate and magnesium sulfate, with a total of more than 300 products, among which there are a number of patented products and domestic exclusive production products, the product quality has reached or exceeded the international advanced standards, and now we are mainly sold to India, Spain, Italy, South Korea and other countries in bulk to meet customers' demand for magnesium oxide.
