At the end of the year, stone paper is 23 cheaper

At the end of the year, Chongqing used stone paper, which was 2/3 less expensive than traditional paper. The stone was beaten into diamond fibers close to microns, plus some resin fibers, which were bonded with adhesives, and then made into paper with professional equipment. Of course, this is not ordinary stone, but calcite. Yesterday, it was learned from the working meeting of the Municipal Trade and circulation industry association that this process of papermaking with stone has been settled in Chongqing

there is no need to use a drop of water in the processing process.

it is understood that calcite papermaking technology is currently only used in Japan and Taiwan, China in the world. Compared with traditional fiber papermaking, there is no need to use a drop of water in the processing process of calcite papermaking. After crushing the ore, 20% of the resin fiber is added to form paper. The process is environmentally friendly, and the power consumption is only 35% of the power consumption of traditional papermaking methods

this project has been settled in Wulong, because Wulong has 160 million tons of calcite industrial reserves. Ye Qinglang, President of the municipal commercial trade and Investment Association, said that the total investment of the project reached 1.6 billion yuan, and six calcite and barite ultra-fine powder production lines were constructed in two phases

by the end of 2009, the first phase will be put into operation, reaching an annual output of 100000 tons of papermaking. In the second phase, the total investment of 1.6 billion yuan was completed in 2010, forming a construction capacity with an annual output of 200000 tons, and the annual sales revenue is expected to reach 4 billion yuan

stone powder is as thin as one thousandth of a hair

how can stone become paper? In this regard, ye Qinglang made a comparison with the way of dough

first grind the stone into powder with professional equipment. Because the ground powder needs to be made into paper, it is very fine, and the stone powder is equivalent to microns. Ye Qinglang said. It is understood that 1 micron = 0.001 mm, which is equivalent to one thousandth of the hair. If a particle of this stone powder is placed alone, it is almost invisible to our naked eyes

and these powders are like flour with dough. Combine these powders with resin fibers and some additives with adhesives in Jinan new era Gold Testing Instrument Co., Ltd. and strictly abide by the production rules, which is equivalent to mixing the dough. Then the dough, which will drive and improve the equipment and technology level of relevant industries, will be sent to professional equipment, and the machine will make it into paper

it can be made into coated paper and writing paper

it is understood that due to the rich reserves of calcite in Wulong, Pengshui and Nanchuan of Chongqing, it was almost useless before making paper, and its value was quite low in the view of Pan Xuezhu. In the press operation, if the oil temperature is too high, it needs smooth oil with good oxidation resistance and thermal stability

due to the price of raw materials, it also directly affects the price of products. It is reported that the price of stone paper produced from calcite will be nearly 2/3 cheaper than that made from traditional technology (such as bamboo and wood)

by the end of this year, Chongqing citizens will be able to use coated paper and writing paper made of stone
