Analyze the overall trend of instrumentation
Natural Graphite, as its name implies, is naturally formed by natural graphite, which is generally found in graphite schist, graphite-gneiss, graphite-bearing schist and metamorphic shale.
Features
The chemical composition of graphite is carbon (C). Naturally produced graphite is rarely pure and often contains impurities, including SiO2, Al2O3, MgO, CaO, P2O5, CuO, V2O5, H2O, S, FeO and H, N, CO2, CH4, NH3, etc. Natural graphite minerals are black, steel gray, striated black; Metallic luster, crypto, dull, opaque; The hardness is isotropic, the vertical cleavage surface is 3 ~ 5, the parallel cleavage surface is 1 ~ 2; Qualitative soft, density is 2.09 ~ 2.23 g/cm3, have the feeling of greasy, easy to contaminate finger. Mineral chip under the transmitted light is generally not transparent, extremely thin can pervious to light, the light green gray, refractive index of 1.93 ~ 2.07, under the reflected light is light gray, reflective pleochroism, Ro gray with brown, Re dark blue gray, reflectivity Ro23 (red), Re5.5 (red), the reflected color, double reflection were significantly, strong heterogeneity, polarization color for straw yellow.
Graphite is a complex six-party double cone, assumes the six-party tabular crystal, common simplex are parallel double, six-party double cone, hexagonal prism, but in good condition with rare crystal forms, the generally show scaly or platy, aggregate density lump, earthy or globular.
Type
The process performance and usage of graphite is mainly depends on the degree of crystallization, in accordance with its natural graphite crystal morphology can be divided into crystalline graphite, Flake Graphite) and aphanitic graphite (earthy graphite) two types of industry.
Crystalline graphite
In the crystalline (scale) graphite ore, the diameter of graphite crystals is greater than 1 mu m. Ore grade is low, but optional; The mineral associated with graphite is usually mica, feldspar, quartz, diopathic stone, diabase, garnet and a small amount of pyrite, calcite, etc., some of which have some useful components, such as rutile and vanadium. The ore is scales, grainy scales or granulocyte structures, flaky, flaky, or blocky structures.
Crystalline (scale) graphite is divided into High Purity Graphite, high carbon graphite, medium carbon graphite and low carbon graphite according to the fixed carbon content.
The high purity graphite (fixed carbon content is greater than or equal to 99.9%) is mainly used for flexible graphite sealing material, nuclear graphite, instead of platinum crucible for chemical reagent melting and lubricant base material, etc.
High carbon graphite (fixed carbon content 94.0% ~ 99.9%) is mainly used for refractory materials, lubricant substrate, brush raw materials, carbon products, battery raw materials, pencil materials, filling materials and coatings, etc.
Carbon graphite (80% ~ 94% fixed carbon content) is mainly used for crucible, refractories, casting materials, foundry coatings, pencil raw materials, battery materials and dyes, etc.
Low carbon graphite (fixed carbon content 50.0% ~ 80.0%) is mainly used for foundry coatings.
Cryptocrystalline graphite
Cryptocrystalline graphite is also called soil graphite or amorphous graphite. In cryptocrystalline graphite ore, graphite crystals are less than 1 mu m in diameter, which are microcrystalline and can only be seen in the electron microscope. High grade of ore, but poor selectable; The mineral associated with graphite is often quartz and calcite; The ore is microscaly - cryptocrystalline structure, block or soil structure.
Cryptocrystalline graphite ore is mainly distributed in contact metamorphic deposits. Actually the diameter graphite flake graphite ore is uneven, the so-called crystalline graphite ore, may also contain the aphanitic graphite, are too many content is often referred to as the mixed type graphite ore, may also contain a small amount of aphanitic graphite quality mineral crystalline flake graphite piece diameter slightly larger than 1 microns.
Cryptocrystalline graphite ore is mainly used in pencil, battery, electrode, graphite emulsion, graphite bearing ingredients and the raw materials of battery carbon rod. The non-ferrous graphite is mainly used for casting materials, refractory materials, dyes and electrode paste.

Instruments and meters will gradually move toward intelligence, networking, and virtualization to meet the development of society and humanity. Instrumentation will be casting a brilliant world in the next decade.
With the parallel development of microprocessors and artificial intelligence technologies, this has given the instrumentation industry an intelligent development, that is to say, intelligent robotic instruments. This intelligent development is also accompanied by the digitization of technology and the level of intelligence. Increased and faster speeds will make people’s lives easier.
For the sake of life's convenience, scientists and technicians will develop instruments in a tiny direction. Just like the development of computers, a small chip can store tens of thousands of commands. This is not just a reduction in volume. It is to increase the accuracy of instrumentation, and the error does not affect the need of production.
Instrumentation also began to advance toward the network, such as: instrumentation automation, multiple instrument networking, multi-media, virtual instrumentation and so on. Combining the latest technology equipment, direct control of instrumentation through wide area networks and local area networks, the company's management, business integration, and application model analysis and other major aspects. Instrumentation companies communicate directly with customers through this platform on the Internet, breaking the limitations of the world and space, direct site information exchange, and expert remote instrumentation maintenance and analysis. High-tech products follow.
With the perfect combination of instrumentation and computer, in order to better satisfy people's satisfaction with the spiritual world and experience the thrill of many people in the world, instrumentation virtualization has begun to develop. It is immersed in accepting objective physical objects and adding a touch of creativity to the United States.
For the overall trend of the instrumentation industry in 2011, the attitude expressed by relevant experts is "cautiously optimistic" - the increase in production and sales will be significantly lower than that in 2010 due to changes in macroeconomics; the increase will be high before and after; the profit growth has been higher than the increase in sales. It is estimated that 2011 will return to normal status. "One thing to note is that the gap between enterprises will obviously increase."
