Light-burned magnesium balls are flex-resistant, pressure-resistant, high-strength, gas-hard, and cementitious materials. They are widely used in national defense, medicine, chemical, papermaking, shipbuilding and other industries. In the building materials industry, it can be used to make placeboards, particleboards, thermal insulation columns, railings, artificial marble, asbestos tiles, ordinary tiles, wall panels, and flooring. With the advancement of technology, the use of light-burned magnesium powder has become more extensive. It can be used for civil products, light and heavy machinery packaging boxes, packaging bottom beams, high-temperature refractory materials, and can also produce beautiful and elegant furniture with high gloss, which can be used in the machinery industry. Cast model.
