How to use and maintain pneumatic tools
The so-called pneumatic tool refers to a tool that uses compressed air to drive the air motor to output kinetic energy. It is a kind of hardware product that is often used in modern construction and machinery industry. With pneumatic tools, it will work for people in related industries. Convenient, but the performance and methods of pneumatic tools also need attention, how to use and maintain pneumatic tools? See how Xiaobian can help you!
Methods and techniques for using and maintaining pneumatic tools:
1. Guarantee the correct generation gas supply system: the inlet pressure is at the inlet of the tool (the outlet pressure of the non-air compressor) is generally 90PSIG (6.2Kg/cm^2). The performance of the tool is too high or too low. life. The air intake must contain sufficient lubricating oil so that the air motor in the tool is fully lubricated (a white paper can be placed on the tool exhaust to check for oil stains, which is normal for oil stains). The intake air must be free of moisture. If the air is not air-dried, it is not appropriate.
2. Do not arbitrarily remove the parts of the tool and operate it. In addition to affecting the safety of the operator, the tool may be damaged.
3. If the tool is slightly faulty or cannot be used to achieve the original function, it can no longer be used. Check it immediately.
4. Use all kinds of tools, be sure to follow the various safety regulations and instructions for use.
5, to use the appropriate tools to work, the tool is too large to cause work damage, too small tools can easily cause damage to the tool.
6. Regularly (about once a week) inspect and maintain tools, add butter to the rotating parts such as bearings, and add oil to the air motor.
Of course, in order to ensure that the pneumatic tools will not be damaged during use, Xiaobian recommends that if you do not operate the pneumatic tools at all, it is best to find professional personnel for construction and use.

Matters concerning the export of Graphite
Over the years, China has been the most * big exporter of Natural Graphite products, in deep processing of graphite products technology leading developed countries, is against the natural graphite "with purchase and adopt a generation of" strategy, and technology blockade, natural graphite as a kind of non-renewable resources, with very good foreground countries limit zhi, its export of primary products, such as export carbon rods, artificial graphite, Graphite Block, pre-baked anode, etc., need to be dealt with the dual-use items.
The price of natural Graphite Powder is determined by three main factors: carbon content, moisture and particle size distribution.
1. The higher the carbon content, the greater the purity of graphite, so the price will rise in the form of the acceleration line (i.e., the higher the purity, the more complex the production process, and the higher the price increases).
The larger the scale, the lower the natural content and the higher the price. Conversely, the smaller the particulate matter, the less content in nature and the higher the price. Therefore, for natural graphite, the price of the normal (i.e., the material at the top of the sieve) is high. In the positive eye, the smaller the number, the bigger the scale and the higher the price. In negative eyes, the larger the number, the smaller the scales, the higher the price, the lower the price of negative items.
Artificial graphite HS codes for 3801100090, customs supervision conditions for export license of dual-use items and technologies, when customs clearance in addition to submit normal trade documents, and shall be submitted to the ministry of commerce issued "export license of dual-use items and technologies".
Materials for application of electronic key for dual-use items:
1. Application of electronic key for approval and approval (seal of enterprise official seal and approval seal)
2. Copy of business license (seal of enterprise)
3. Photocopy of the record registration form of foreign trade operator or a copy of the approval certificate of the foreign-invested enterprise (with the official seal of the enterprise)
4. Applicant's identity card and copy of the company's legal person identity card (seal enterprise seal)
5. Service contract (please refer to the representative office or office)
6. Copy of bank payment receipt (wire transfer voucher, bill)
Information on import and export of dual-use items
1. Trade contract
2. Export (import) packing list
3. Certificate of final user and end-use abroad
Application for export license of sensitive items and technologies of the People's Republic of China, etc.
