Types of products impregnated with graphite

(1) Small specification graphite electrodes and joint blanks, various specifications of graphite anodes, fine structure, high-strength, and high-density graphite. These products need to have high density and strength, as well as low electrical resistivity, so the baked semi-finished products are first impregnated with coal tar pitch and then graphitized.(2) Diaphragm type salt solution electrolysis cell graphite anode. Graphite anodes impregnated with coal tar pitch can generally last for 8-9 months, while graphite anodes that are not impregnated can only last for 5-6 months. The main reason for affecting the lifespan of graphite anodes is that the electrolyte penetrates into the pores of the anode, while hydroxide ions, sulfate ions, and hypochlorite ions in the electrolyte discharge on the anode, generating primary oxygen. This initial oxidation reaction of oxygen on the anode causes chemical corrosion, which accounts for about half of the loss. Additionally, chemical corrosion weak

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.

How much temperature can the high -temperature -resistant graphite board be held?

How much temperature can the high -temperature -resistant graphite board be held? Graphite and golden steel are a kind of homogenic alien in carbon. There are many types of graphite products manufactured by graphite raw materials, such as graphite rods, graphite molds, high temperature resistance graphite boards, etc. The structure of high -temperature graphite board is an atomic crystal. In the middle of the oxygen atom, it is connected to a covalent price to cause a porous material that stabilizes the positive hexagon. The covalent single -key is a ion key with high keys that can be damaged with high mechanical energy.Many consumers will ask, how much temperature can high temperature resistant graphite board be held?From the perspective of characteristics, high -temperature graphite boards can resist high temperature, and there is no all problem at 1200 degrees. The more high -quality graphite board can bear high temperature above 3000 degrees. High temperature resistance graphite b

Types, properties, and uses of mechanical carbon graphite products

Mechanical carbon graphite products are carbon graphite materials used as structural components in various machinery, including various graphite bearings, graphite sealing rings, graphite piston rings, graphite sliding plates, and graphite brake friction plates.According to different production processes, mechanical carbon graphite products are mainly divided into 7 categories: (1) carbon graphite; (2) Electrochemical graphite; (3) Resin impregnated carbon and electrochemical graphite; (4) Carbon and electrical graphite impregnated with metal; (5) Carbon graphite material with resin as binder; (6) Metal - graphite material; (7) Flexible graphite material.Mechanical carbon graphite products can work in corrosive media within the temperature range of -200~2000 ℃ and operate normally without lubricating oil at high motion rates. They have self-lubrication, good wear reduction performance, high thermal conductivity and heat shock resistance, low linear expansion coefficient, and good mech

The shortcomings and prevention of graphite mold heat treatment process

What should I pay attention to when applying graphite machinery and equipment

1. Be careful when transporting or hanging. Do not drag and drag it on the ground. Do not pry up or use a galvanized steel wire rope to be tied immediately. Essence2. After the total installation, when welding or oxygen cutting of the steel case, it should be ensured that the safety of graphite and hydraulic sealing should be ensured (water can be injected in the shell), otherwise graphite should be removed.3. When connecting the external flanges, it is not forcibly installed. When the foot bolts are tight, the symmetry is symmetrical.4. The export and export valve of the opening and closing machine equipment should be slow to prevent the significant impact of raw materials.5. The application of materials, temperature and work pressure in applications should be strictly strictly in accordance with the requirements of the design plan.6. For the electric heater, when driving, you should first pass the raw material and pass the vapor; when used as a cooling or cooler, you should first pa

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

How is high carbon graphite made?

The flotation method for extracting high carbon graphite has the lowest energy consumption, reagent consumption, and cost in mineral purification. This is the biggest benefit of flotation method for purifying high carbon graphite. But when using flotation method to purify graphite, it can only make infinite progress in the grade of graphite. Regarding flake graphite, it is not only impossible to dissociate its complete monomer, but also not beneficial for maintaining the large scale of graphite. To obtain high carbon graphite with a carbon content of over 99%, it is necessary to use chemical methods to purify the graphite.（1） High carbon graphite alkali acid purification method. The carbon content of graphite purified by alkaline acid method can reach over 99%, with characteristics such as low one-time investment, high product grade, and strong process adaptability. It also has strong universality. The purification of non-metallic minerals can accept the advantages of alkaline acid me

How to distinguish whether Gwangba is clean and tidy?

1. Determine that the graphite boat has no acid and alkali ingredients. (After immersion, you can use pH to detect water or graphite boats that have been used as neutralized to determine the results of the cleaning.)2. Check out the surface layer, graphite guarding point and graphite boat, and whether there are residues of silicon nitride.3. Try the ceramic stick and porcelain sleeve with the dust -free paper -free paper -free paper -free paper.Remarks: The above rules are distinguished under the processing process of all normal washing boats. When the ceramic stick is broken during the whole process of laundering, the insistence is too large, and it needs to be immediately disassembled to prevent everything that endangers the graphite boat. Normal application.
