Taishan jade English name taishanjade is a serpentine jade produced in Taishan Mountain. According to the "Shan Hai Jing" records: "Taishan is on the top of the jade ····· The water is flowing out, the east stream is injected into the river, and the water is jade. Before the Qin and Han Dynasties, Taishan Jade was famous in China, until the contemporary people wrote "Five Yuezhi", and there are records of "Taishan Fangyuan forty-four, Duozhimei jade".
Taishan jade has a small amount of reserves, and it is called "Zhenshan jade" and "dispelling evil jade". Taishan jade is produced in the western part of Mount Taishan. It has been named by experts. According to the color, it can be divided into three kinds of green jasper, black ink jade and duck egg blue jade spot jade. The hardness is 4.5-6, the relative density is 2.53~2.85, translucent. To micro-transparent. Small black spots (about 2 to 3 mm in diameter) often containing magnetite, and also have pyrite-distributed pyrite with a particle size of less than 1 mm. The latter flashed a little gold after polishing, adding a bit of beauty.
Taishan jade, produced in the foothills of Taishan Mountain, Tai'an City, Shandong Province. The stone is serpentine jade, dense blocky, delicate and warm texture; the color is mainly green, with green, dark green, black and other colors, the stone contains black and yellow spots; translucent to slightly transparent, grease, waxy luster The hardness is about 5.8 degrees. Its varieties are: Taishan Jasper, Taishan Moyu, Taishan Cuiye jade.
Taishan jade was developed earlier, and it has been famous in the pre-Qin period. It is a good material for carving handicrafts. Taishan jade is a kind of serpentine rock, which is a metamorphic ultrabasic magma deposit. It is mainly distributed in Fangzhuang Village and Shishao Village of Daolang Town. It is a symbiotic deposit of Taishan jade, serpentine and chrysotile. The source of serpentine is about 12 million tons. Taishan Moyu: The texture is fine, the color is black and crystal, and it is green in the sunlight. After cutting into a sheet, it shows various transparent or translucent patterns, which is very appreciated. Taishan Jasper: The texture is crystal clear, green is like Xiahe, with dark green, dark green, dark green and other colors, especially fresh green is better. Taishan Cuiye Jade: Also known as Baiyun Jade, the color is as clean as snow, and there is a light green pattern.
Although Taishan jade has this legend since ancient times, where exactly does Taishan jade actually exist? How much is there? There is no exact record. In May 2009, the Fifth Geological Exploration Institute of Shandong Provincial Bureau of Geology and Minerals was located in Taian, Xiqiao, Taishan. During the geological survey of Shila Village, Congee Street, Daiyue District, a large reserve of jade deposits was discovered. According to preliminary estimates, the reserves are over 9 million tons, the deposits are strip-shaped, and the operating area is about 4 square kilometers. It is about 100 meters or less.
The stone is serpentine jade, dense block-like, with a hardness of 5.8 degrees. It is formed in the Taidian sub-unit of the Nanpupo super-element of the Neoarchean Luping period. The lithology is metamorphic ultrabasic rock, forming time 25 Billion 36 million years. The formation process is deep intrusion along the tectonic intrusion, and the magnesium-rich ultrabasic rock is metamorphosed by high temperature gas-liquid, which belongs to metamorphic ultrabasic magmatic deposit.
Matrix body fixed cutters are made from tungsten carbide material. This provides improved wear resistance and erosion.Additionally, they are typically more heavy set as far as cutter count.In applications of high fluid volume or high sand, matrix body PDC bits offer longer life and multiple bit runs.
PDC Drill Bits are equipped with Hardened Alloy Steel base material;High performance PDC-Cutters;Carbide and Diamond gauge protection;Carbide/Diamond Shock Studs;Threaded or Plain Carbide Nozzles for Flushing
Above features are subject to changes and modifications according to customers' requirements.
Matrix Body PDC Bit advantage :
1. Force balanced, resist impact to the blade during high-speed drilling, to make bit work stable.2. Plus wear knot section, reduce collision in the high-speed rotational vibration.
3. Patented matrix formulation, extended bit life.
4. Optimal hydraulic design, easy to move out the drill cuttings and cooling.
5. Equipped with back reaming Cutters.
6. The cutter is high performance to increase the ability of anti-impact and anti-abrasive
Characteristics of Matrix body PDC bits
1.PDC Cutters of different features are selected and bit profile design is optimized to suit different drilling applications in different formations to satisfy different requirement when drilling soft to medium hard formations
2.Cutting structure is force balanced ,non-symmetrical blade and wide gage are designed so that the bit drills more stable and resulting longer working life of the bit
3.Better wear resistance and higher strength of the bit are guaranteed in regard to material and structure by using matrix body material with self-owned intellectual property rights and combining FEA analysis technology.
4.Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.
5.CNC sintering process uses full automatic control. Inside and outside temperature of the bit is monitored during all procedures to fully embody material properties as well as ensure uniformity and stability of product quality.
