Introduction to stone paper and popular science




Stone paper is based on limestone mineral resources with large reserves and wide distribution as the main raw material (calcium carbonate content is 70-80%), with high polymer as auxiliary material (content is 20-30%), using polymer interface chemistry and polymerization The characteristic of the material modification is that it is processed through a special process, and then made through polymer extrusion and blow molding processes.

Stone is a new type of material between paper and plastic. It can not only replace some traditional functional paper and professional paper, but also replace most traditional plastic packaging. And it has the characteristics of low cost and controllable degradation, which can save a lot of cost for users without causing pollution. From the perspective of replacing traditional paper parts, it can save a lot of forest resources for the society and reduce the secondary pollution generated in the papermaking process; from the perspective of replacing traditional plastic packaging parts, it can save a lot of strategic resources for the country. (Each ton used can save 2.3 tons of fuel), the product can be degraded after use, and will not cause secondary white pollution. Environmental protection new materials The stone paper industry has a wide range of materials, and the space for product upgrades, technology upgrades, and application areas is very broad. It is a sunrise industry with strong vitality.

Stone paper can protect resources and save energy. The stone paper comes from the mine and does not need to be felled. This is a great protection of the forest. The production process of stone paper mainly uses calcium carbonate as the main raw material. There is no need to add a drop of water throughout the production process, saving precious water resources. At the same time, energy consumption is lower than that of traditional wood pulp papermaking, which helps to improve global warming caused by carbon dioxide. Reduce pollution emissions. The production of stone paper does not require washing with water, strong acids, strong alkalis, and bleaching agents. Therefore, there is no wastewater discharge problem, and no water resources are polluted. Recycling and degradation. After the stone paper is used up, it can be recycled through plastic products. After collection, it can be crushed and squeezed to reproduce colorful plastic bags, flower pots and plastic buckets.
