1. One ton stone paper can save 20 trees.
2. One ton stone paper can save 280Kw /H electric energy .
3. One ton stone paper can save 7480 gallons clean water.
4. The stone paper production area was only 1/10 of the traditional fiber factory.
5. Stone paper production need only circulating cooling water, the traditional fiber paper produce a large amount of waste water.
RICH MINERAL PAPER HISTORY
Stone paper is also called rich mineral paper which is made mainly from dusty stone with 15% percent polyethylene and 5% percent adhesive. This kind of paper is waterproof, hard and uninflammable, and the most important thing is that there is no need to cut trees, which is very environmental.
The paper made from stone looks ordinary from the appearance, but if you write something and immerse it in water for ten minutes, the character is same as before, and the paper still can be written when you make it dry. If you burn rich mineral paper and general paper at the same time, you will find that the general paper burns to the ground quickly , on the contrary, fire of rich mineral paper is becoming smaller and smaller till it puts out.
The technology was developed successfully in domestic in the 1970s. However, it failed to get promoted because of the neglect to environmental protection and the situation of cost at that time. In recent years, rich mineral paper has made some breakthrough in the aspect of technology so that the reversal of cost took place and it is widely used now, such as notebook, paper bags and plates. At the time of taking environmental protection seriously, the technology will draw much attention from people gradually.
The new kind of paper is made from much inorganic mineral powder and little plastic resin whose function is similar to traditional wood pulp paper. It has got patents in more than forty countries, China, America, England, France, Germany, Italia, Australia and Canada and so on. Its working process is a unpolluted way without cutting trees, using water, discharging of gas and wastewater. Besides, rich mineral paper is recyclable. It will turn into dust after isolation without waste and then return to nature. It meets the standard of American Food and Drug Administration.
The types of rich mineral paper
According to the above-mentioned target markets, at present, there are different kinds of paper because of their nature differences. The main four kinds are: RP, SP, TR, TS, JG and JM.
The differences of rich mineral paper
The new wood free pulp mineral paper takes environmental protection cost, raw material, machinability, market acceptance and futurity into consideration. Although it can't totally take traditional paper's place, it has the similar quality to traditional paper with the physical property of composite paper. We make a comparison among wood pulp paper, composite paper and rich mineral paper.
The features of rich mineral paper
Good quality and low cost
Extensive uses. It can not only take traditional paper's place but also has good absorbency, waterproofness and foldability, and it is easy to bind.
It can replace opaque PVC, PP, PE and PET plastic film to cut cost, and is also suitable for making disposable goods like various packing bags, shopping bags, reticule, plates and cups.
For other specific printing purposes.
The characteristics of rich mineral paper
The development in paper characteristics of rich mineral paper includes safety, physical property and other characteristics. Its main characteristic is waterproof, anti-fog, grease proofing and insect prevention, and in the aspect of the physical property, its tearing resistance and folding resistance is better than wood pulp paper. We make analysis according to its characteristics, needs and the target market for future development.
Rich mineral paper's absorbency of ink is good, and its inkjet printing is waterproof and cannot be etched because of nano stone batter. The definition of rich mineral paper is higher even up to 2880dpi because of its fibreless. There is no color cast and decoloration because chemical action will not take place with ink without the membrane. In general, the 720dpi accuracy of rich mineral paper amounts to the 140dpi accuracy of traditional paper.
The working and recycle process of rich mineral paper
Rich mineral paper is turning stone minerals into powder with plastic and auxiliaries instead of wood pulp paper and plastic film. The main ingredient of this environmental paper is 80% percent mineral substance ( stone powder). This patent is worked out with calcium carbonate fro marble mine in Hualien area in Taiwan and environmental PE material, then the paper that meets standard with good quality and low cost was developed successfully after the process of mixing raw material, prilling, film building and coating. At the same time, it can replace the present paper with high cost and high order.
Besides, this series of paper can recycle, even if it is thrown in nature, mineral flour will be resolved and returned to nature after irradiating without pollution.
The uses of rich mineral paper
Decorative wallpaper, carton, paper box, coated paper, cigarette paper, label, card, advertising decoration paper and flat envelope; in special aspects, such as field operation paper, underwater operation paper, undermine operation paper and military paper. Its uses are really wide and it also will be wider with the development of paper technology. The cost of rich mineral paper goods is lower 20-30 percent than alternative paper goods with powerful competitiveness and bright market prospect.
