Light-burned magnesium balls are flex-resistant, pressure-resistant, high-strength, gas-hard, cementitious materials. They are widely used in national defense, medicine, chemical, papermaking, shipbuilding 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, 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 heavy machinery packaging boxes, packaging bottom beams, high-temperature refractory materials, can also produce beautiful elegant furniture with high gloss, which can be used in the machinery industry. Cast model.
