What industrial chemicals should I order from China?

Basics

China's chemical industry has been developing steadily over the past 10-15 years. The export of goods from this category to the CIS countries is steadily increasing.

Chinese specialists are constantly working on setting up equipment, they use the best raw materials, which allows you to get the final product with virtually no loss. The following are the main product categories that you should pay special attention to.

Graphite PGM

Production is carried out from uncalcined petroleum coke. It can be oil, which has a low ash content, products of secondary processing of petroleum products. Manufacturers monitor the level of cleanliness. It is achieved under the influence of high temperature, under special control is the gaseous environment.

Initially, the coke must be heated to a temperature of +1200 degrees. Then the material is placed in a special autoclave. After that, graphitization is carried out at a temperature of no more than 3000 degrees.

What is the reason for the increased strength? It is associated with the fine-grained structure of graphite. The material can be modified to enhance performance. The impregnation takes place with coal tar pitch or salt solutions.

A common form is a cylinder with a height of 180 mm. In addition, there are even bars with sides of 100 mm. There are many other release options available.

Scopes of PGM graphite

1. Making crucibles for vacuum furnaces.
2. Create electrodes for rigs and machines.
3. The material is used in the production of molds, heaters, grippers, discs.

You can right now buy PGM fine-grained durable graphite on favorable terms. It is offered at a bargain price in China.

About isostatic graphite

The material is devoid of many of the disadvantages inherent in other grades of graphite. Unique technologies made it possible to rid it of anisotropy. This is due to the layered structure. The atoms are parallel to the layers here. Other features to be aware of before purchasing are listed below.

1. Isotropy - physical properties are uniform in all directions.
2. Increased density and firmness.
3. Fine grain.
4. Long service life in demanding environments.
5. Material does not heat up to 700 K.
6. Inert to most chemical compounds.
7. Increased thermal conductivity.
