Imported diamond mining machine

1. In the cave, if you have a list of admission, find five stones, go to Qingmu forest to find koala identification, and have a mining machine.

2. Considering the cost, man-made stone is better, both granite and quartz can be used. However, if only one or two pieces are needed, it is difficult to find man-made stone of black diamond color, because the cost of color matching is relatively high; There is no requirement for color effect to be ignored

other issues need to be considered: aging, processing and installation (rounded corners are required to test the processing technology; The hardness of the stone to be processed on site needs to be considered), the beauty (artificial stone can be made similar to natural stone),

3.

diamond wire saw, also known as diamond wire, refers to the use of electroplating process or resin bonding method to fix diamond abrasive on the wire

There are mainly two types of tools:

1. Electroplating type: a linear superhard tool made by depositing a layer of metal (generally nickel and nickel cobalt alloy) on the metal wire by electroplating and consolidating diamond abrasive in the metal. Metal coating is bond, diamond abrasive is used for cutting

The electroplated diamond wire saw can be made into different diameter and length according to the need; Wire saw can be installed on different equipment to form different processing methods, such as reciprocating cycle (saw frame), high-speed band saw, wire cutting and so on. For the processing of hard and brittle materials, wire saw can not only cut thin sheets, but also process curved surfaces, and can also be used for the study of small holes. At present, Nanjing sanchao New Material Co., Ltd. is a relatively mature enterprise in domestic proction of electroplated diamond wire saw, with early R & D investment and strong technical strength

2. Resin type: the diamond abrasives are consolidated on the metal wire by using resin as binder

4. Diamond grinding wheel you only need to provide size specifications, your requirements, manufacturers can help you customize. It's better for you to provide more detailed parameters, so that the manufacturer can adjust the hardness and mesh of the diamond head, so as to meet your requirements. Generally, the effect is not very good. The best grinding wheel should be selected according to the proct you grind. If you need to, you can contact me.

5. Generally speaking, it is through good news. If there is good news, it will rise, but not necessarily. The rise of bitcoin, Ruitai coin, qianjinka and Laite coin is generally e to good news, but now the role of good news is not so big.

6. A: in fact, Z & Y diamond grinding wheel should not be imported.

7. According to the 2018 China customs declaration manual, the HS code of diamond cutting machine is 8461500090, the export tax rebate rate is 17%, and the value-added tax is 17%; The most favored nation tariff is 12%, the common nation tariff is 50%, and the customs supervision condition is none, indicating that the Customs has no special supervision condition for the import or export of the goods
data required for export customs declaration: customs declaration form, packing list, invoice, contract and power of attorney for customs declaration
data required for import: Bill of lading, certificate of origin, packing list, invoice, contract, power of attorney for customs declaration and other data considered necessary by the customs.

8. What tools do you need

9. Title: emery
subject or key words: Materials Science
content
in 1891, American Acheson mixed clay and coke in an iron bowl in an attempt to convert carbon into diamond by electric arc. But the result is that there is a hexagonal crystal near the electrode, which is different from the cubic octahedron of natural diamond. Acherson thought that it might be a new compound formed by the reaction of carbon and alumina in clay. Because there is a kind of alumina mineral called corunm in nature, he combined the two English words of carbon and corunm as the name of this new compound, which was translated into "Emery" by Chinese scholars. Later it was known that this compound was silicon carbide, which was formed by the reaction of silicon dioxide in clay with carbon at high temperature
the cell is face centered cubic structure, each cell contains four C atoms and four Si atoms. The structure is similar to that of diamond
the hardness of silicon carbide ranks the fourth in inorganic materials after diamond, boron carbide and cubic boron nitride. At present, high density silicon carbide can be obtained by hot pressing sintering. It has high strength and good oxidation resistance, and does not deform at high temperature. It can be used as turbine blade of high temperature gas turbine, as wear-resistant sealing material, as nozzle of rocket nozzle and light bulletproof material.

10. Like other units, there are no strict professional restrictions, but most of them are public health professionals, including clinical professionals. However, it should be noted that after entering the hospital, it is generally not allowed to test for the qualification of doctors, but only for the title of public health, such as health professional management and prevention.
