The so-called Pharmaceutical Intermediates, refers to the production of pharmaceutical products in the process, the use of raw materials, materials, accessories and other intermediate products. In fact, some of the chemical synthesis process for the chemical raw materials or chemical products. This chemical products, do not need the production license of drugs in the ordinary chemical plant can be produced, as long as some of the level, can be used for the synthesis of drugs.

When choosing arc-shaped slide wire should pay attention
When selecting arc-shaped slide wires, precautions should be taken:
1. Radius size
When making arc safety slide lines, the minimum required radius is 1.5 meters. If the radius is too small, the current collector may not turn normally, resulting in power failure.
2. Accessories calculation
Because of the curvature of the curved arc contact line, the requirements for the bracket are higher than those for the straight section. Especially the smaller the radius, the greater the bracket density needs to be.
3. Installation requirements
Before making the arc-shaped trolley line, it is necessary to determine which side of the trolley the trolley line is mounted on. Because the inner and outer sides have different required trolley line radii, it is best to provide accurate drawings to avoid unnecessary trouble.
4. Model selection
Generally, there are no large requirements for the power of mobile equipment for arc bending. Therefore, there are tubular safety wire contacts and unipolar safety wire contacts. The choice of model can be determined based on the current size and installation space. If the current carrying capacity is greater than 120A And there is enough space for installation. It is recommended to use a single-pole safety wire. If the installation space is limited or the current is very small, a multi-pole safety wire can be selected.
