Graphite flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

The effect of battery dedicated graphite as negative electrode on lithium ion power battery fast charge performance

Method for manufacturing low-density expanded graphite blocks using flexible graphite

In recent years, various types of low-density carbon graphite materials have been actively studied, including carbon (graphite) foam made of mesophase pitch or polymer resin, and carbon nano foam formed when carbon materials are ablated by high repetition rate pulsed laser. Expanded graphite is also a low-density carbon graphite material. Due to the simple preparation process, low production cost, and convenience for large-scale industrial production of expanded graphite, research on expandable graphite has continued to deepen in recent years. The following editor from Jinhui Graphite Company introduced the method of making low-density expanded graphite blocks by soaking flexible graphite in concentrated acid:The worm like shape and weak macroscopic structure of expanded graphite limit its application. If a stable and expandable graphite block can be made, it will be beneficial for expanded graphite to play its role as a functional material for adsorption, insulation, thermal conducti

1. Prevention of strong corrosion of flame direct -injection engine graphite products side and bottom 砣;2. Use the entire process to turn the graphite boat once a week to improve the use period of graphite products;3. A proper interval should be kept in the middle of the graphite boat and the furnace wall, and graphite products should be put in the middle of the furnace;4. Pull out the coal ash and sticky conditions in the form of the form should be gently patted to prevent damaging graphite products;5. In the transportation conditions, it is necessary to hold it lightly, and it is strictly forbidden to fall;6.

What is the difference between expansion graphite and expansion graphite?

1. Expanded graphite crystal is a typical laminar -like carbon material. Put other alien particles such as atoms, molecules, ion, and even atoms into the crystal graphite layer in physical or chemical methods to generate a new layered compound , Called inter -laminate compounds, can expand graphite. Can expand graphite and expansion graphite are different. Seal the sealing strip should choose expansion graphite.2. After the fire -resistant glass grouting, it is divided into two cases: glass rupture and glue. The glass rupture is caused by the small and small strength of the glass, or the glass area is too large. Generally, the grouting process can be solved. That shows that the quality of the glass glue you choose, or the glass glue is caused by completely solidifying. Specific questions can leave a message for me to discuss privately.
