The present situation of polycrystalline diamond composite film industry is that the composite material of polycrystalline diamond thin layer adhered to the hard alloy substrate is called diamond composite film, codenamed PDC. With diamond polycrystalline diamond compact with extremely high wear resistance and cemented carbide of high impact, and diamond layer can always maintain sharp cutting edges, thus in the oil and geological drilling in soft to medium hard formations, the effect is very good. The diamond content in the composite film is as high as 99%, so the diamond layer is extremely hard and has excellent abrasion resistance. The hardness of the diamond is (6.5 ~ 7) x 104 mpa, or even higher. Its thickness is very thin, general control is about 0.5 ~ 1 millimeter. It is welded to the drill bit, its cutting edge is sharp and always self - sharp, also known as micro cutting tool bit. Because of its superiority, the composite film has been developed and produced at home and abroad. American GE company is the first to launch compound in the manufacturer of the chip, its main products are compax, produce stratapax again, after the latter for drilling is special product, its wear resistance than high l00 ~ 150 times of hard, can be comparable to natural diamond. Others, such as South Africa and Japan, introduced different types of composite films in the 1970s and 1980s. China began to be developed in the early 1980 s, PDC in 1975, chengdu tool developed by FJ series with PDC tool, in 1979, developed by Beijing artificial crystal JYF type PDC blade, in 1981, guiyang our 6 developed the JFS - F series PDC blade, in 1987, zhengzhou institute of abrasives grinding successfully developed the oil drilling with PDC, 1988 for small batch production, commodity code JFZR, in 1990 to form a new company to realize large-scale production, greatly accelerate the PDC to popularize and apply in our country. Up to now, the domestic PDC specification is complete, basically can meet the needs of national economy development. Clever and core of polycrystalline diamond compact monitoring and the industry has many years of market research, clever and real time control of the polycrystalline diamond compact core industry market law of development and the latest dynamic, a large number of closed agglomeration crystal diamond compact industry market and the latest information of enterprise development, accurate and timely integration of polycrystalline diamond compact status of development of the industry at present. Combined with years of polycrystalline diamond compact the law of development of the industry, experts and research team integrated a lot of information, integration of the "2015-2020 China polycrystalline diamond compact industry present situation and investment analysis report, for future development of polycrystalline diamond compact industry trends and make a clear analysis and forecast the prospect of investment.
