The first advantage of stone paper is that it has the advantage of raw materials. paper stones,Traditional papermaking consumes a lot of wood, while stone papermaking uses calcium carbonate, the most abundant mineral resource in the earths crust, as the main raw material. Second, there are environmental advantages. The entire production process of stone papermaking does not require water, which saves pollution links compared with traditional papermaking processes. At the same time, the incineration and recycling of stone paper will not produce black smoke, and the remaining inorganic mineral powder can also return to the earth and nature. Disadvantages of stone paper 1. Dust (floating dust) problems in the production process of stone papermaking The second is the problem of raw materials. The raw material used is mainly calcium carbonate, which has poor natural regeneration ability. The third is the issue of recycling. The minerals contained in this product can be embrittled, decomposed and returned to nature, but it is impossible to concentrate and return to use. like: Characteristics of stone papermaking process What impact does stone paper have on the environment? |
