Problems solved by technology

In addition, the production process of existing thermal insulation materials or thermal insulation materials is relatively complicated. For example, magnesium silicate requires three steps of polymerization. First, it needs to be soaked (about 4 hours) before the synthesis reaction (about 90 minutes), and then add pearls. after rock, resynthesis
