Magnesium oxide mainly plays the following roles in BMC pellets:
Thickener: Magnesium oxide is an inorganic, non-toxic white powder with good water absorption and dispersion. Adding magnesium oxide to BMC aggregates can absorb free monomers in the resin, thereby increasing the viscosity of the resin paste and making it easier to form.
Filler: Magnesium oxide is a heavy filler that can increase the density and strength of BMC pellets.
Heat resistance improver: Magnesium oxide has good heat resistance and can improve the heat resistance and corrosion resistance of BMC aggregates.
In BMC pellets, the dosage of magnesium oxide is generally 5%-15%.
Specifically, the application of magnesium oxide in BMC aggregates includes the following aspects:
Improve the fluidity of BMC aggregates: Magnesium oxide can absorb free monomers in the resin, thereby reducing the viscosity of the resin, making the BMC aggregates easier to flow and facilitate molding.
Improve the strength of BMC pellets: Magnesium oxide is a heavy filler that can increase the density of BMC pellets, thereby improving its strength.
Improve the heat resistance of BMC pellets: Magnesium oxide has good heat resistance and can improve the heat resistance of BMC pellets so that it can still maintain good performance in high temperature environments.
Improve the corrosion resistance of BMC aggregates: Magnesium oxide has good corrosion resistance and can improve the corrosion resistance of BMC aggregates so that it can still maintain good performance in corrosive environments.
The application of magnesium oxide in BMC aggregates has the following advantages:
Low cost: Magnesium oxide is a low-cost filler that can effectively reduce the cost of BMC aggregates.
Excellent performance: Magnesium oxide has good thickening, filling, heat resistance and corrosion resistance, and can meet various performance requirements of BMC aggregates.
Wide range of applications: Magnesium oxide has a wide range of applications in BMC aggregates and can be used to manufacture various BMC products.
Magnesium oxide is an important additive in BMC pellets and plays an important role in improving the performance of BMC pellets.
