Intermediates are also called organic intermediates. Use coal tar or petroleum products as raw materials to manufacture intermediate products such as dyes, pesticides, medicines, resins, additives, plasticizers, etc. Because it was originally used to make dyes, it is also called dye intermediates.
Pharmaceutical supplies
Concept
The so-called Pharmaceutical Intermediates are actually some chemical raw materials or chemical products used in the pharmaceutical synthesis process. This kind of chemical product does not require a production license for drugs, and can be produced in ordinary chemical plants. As long as it reaches some levels, it can be used for the synthesis of drugs.
Effect
Pharmaceutical production requires a lot of special chemicals. Most of these chemicals were originally produced by the pharmaceutical industry. However, with the deepening of social division of labor and the advancement of production technology, the pharmaceutical industry has transferred some pharmaceutical intermediates to chemical companies for production. Pharmaceutical intermediates are fine chemical products, and the production of pharmaceutical intermediates has become a major industry in the international chemical industry.
In cell biology, the intermediate refers to the middle part of the gradually disintegrating spindle around the equatorial plane in the late stage of cell division, and the surrounding cytoplasm concentration increases, filling the entire equatorial plane.

In November 2005, the Three Gorges Corporation asked the car company to build a 40-ton wrecker for them and requested delivery in mid-December. At present, including China United, only three domestic manufacturers have the ability to make 40 tons of wreckers, and because the product safety performance is not guaranteed, it is rare to enter the market.
Three years ago, the winning bidder of the production of wreckers started the development of 40 tons of wreckers. However, for various reasons, there was no product for sale. In May last year, the winning bidder turned the project together. The Pudong Special Vehicle Company, the centralized production unit of the Zhonglian Group wrecker, was given research and rectification.
In the case of tight time and heavy tasks, the car company set up a 40-ton wrecker rectification team headed by the chief engineer Liu Guoliang. On the basis of the development of the winning bidder, after more than a month of intense work, it was finally completed on schedule. The rectification and trial mission was successfully carried out on the 19th.
The 40-ton wrecker developed this time is equipped with advanced configuration. It adopts the original Mercedes-Benz chassis imported from Germany, which greatly improves the reliability of the vehicle. It is equipped with an electronic control system and uses the computer to display the working conditions, so that the operator can rotate the arc. The working condition parameters such as the lifting angle are clear at a glance; in addition to the conventional safety device, a torque limiter is additionally installed. Once the weight of the lifting device exceeds the rated weight, the operating system will be automatically cut off; two winches can be installed. It can expand the function of the wrecker, save the ambulance cost of the vehicle, and make the situation that the wrecker and the crane move at the same time become history; expand the scope of work, the maximum working distance is more than 40 meters, and ambulance for complex terrain Work has increased convenience.
At present, the development of wreckers to large and medium tonnage is a trend. The development of the 40-ton wrecker was successful and went to the market, which seized the market opportunity and greatly improved the Pu's ability to develop and manufacture wreckers.
According to the information from the Three Gorges Corporation, the Pudong 40-ton wrecker has successfully carried out three difficult rescues and is in good working condition. At the same time, they also expressed their intention to continue cooperation with Pudong next year.
On December 26, 2005, the marketing department of Pu'er Bus Company received a call from the Three Gorges Corporation. On the phone, a business person in charge of the Three Gorges Corporation was responsible for the performance of the PuTang 40-ton wrecker that was just put into use. Give a high rating.
