Good scope of application. Through the application of a variety of new technologies, stone paper products have many new characteristics that ordinary paper does not have: such as high strength, anti-fog, oil-proof, insect-proof, long elongation, moisture resistance, corrosion resistance, tear resistance, and folding resistance And so on, so it has a wider range of uses than ordinary paper. The various packaging bags, feed bags, cement bags, clothing bags, raincoats, tablecloths, wallpaper, special paper products, etc. made by it have multiple characteristics such as low price, high load-bearing, waterproof, dustproof, and mothproof. The comprehensive advantages of this kind of packaging. Therefore, the scope of its application theoretically, stone paper seems to be able to replace most of the traditional paper, including cultural paper, industrial paper, packaging paper, information paper and special paper. For example, it is used to print beautiful wall calendars, posters, book covers, illustrations, art books, picture albums, children's books, various exquisitely decorated packaging, paper handbags, labels, trademarks, etc.; and high-end printing for exquisite printing Posters, maps, notebooks, product manuals, textbooks, magazines, etc. In addition, there are special papers such as paper for underwater operations, paper for field operations, paper for underground operations, and paper for military field operations.
Has a huge raw material cost advantage. Traditional papermaking consumes a lot of wood, while stone paper uses calcium carbonate, the most abundant mineral resource in the earth’s crust, as its main raw material. Calcium carbonate is mainly derived from calcite, marble, limestone and other ores, which are extremely abundant in storage in China, and the price is comparable. Cheap, the cost of its ultrafine powder is less than 1/10 of the cost of wood pulp fiber; while the resin polymer material derived from petroleum accounts for only about 25%. When the price of petroleum is not very high (such as the price of crude oil 100 US dollars per barrel), the overall cost of stone paper is significantly lower than that of plant fiber paper. Without including the production cost, the raw material cost of wood pulp fiber paper is about 25% higher than that of stone.
It has obvious environmental advantages and environmental costs. The entire production process of stone papermaking does not need water, does not need to add a large amount of strong acid, strong alkali, bleaching powder and many organic chlorides, and saves several important pollution links such as cooking, washing, bleaching and drying compared with the traditional papermaking process.
