How to solve the corrosion of the device in the scale graphite?

How to avoid the corrosion of the equipment on the equipment, thereby reducing equipment investment and maintenance costs, and improving production efficiency and profits is a problem that each chemical enterprise always needs to solve. Many products are resistant to corrosion but not high temperature, but scales graphite has both advantages. The following editors will introduce the problem of the device corrosion in detail how to solve the equipment of the scales:1. Excellent thermal conductivity. Scales graphite also has good thermal conductivity. It is the only non -metallic material with a thermal conductivity higher than the metal. The thermal conductivity coefficient is 2 times that of carbon steel and 7 times that of stainless steel. Therefore, it is suitable for heat transfer equipment.2. Excellent corrosion resistance. Various types of carbon and graphite have excellent corrosion resistance to all concentrations of hydrochloric acid, phosphate, and hydrofluoric acid, includin

Graphite crucibles have good thermal conductivity and high temperature resistance

Graphite crucibles have good thermal conductivity and high temperature resistance. During high-temperature use, their coefficient of thermal expansion is small, and they have certain strain resistance for rapid heating and cooling. Strong corrosion resistance to acid and alkaline solutions, with excellent chemical stability.But the following points should be noted:1. To avoid damage to the graphite crucible caused by impact or falling from a height. Be careful when using, handle with care, and take a look at the surrounding environment.2. The graphite crucible must be strictly protected from moisture and must be stored in a dry place or on a wooden frame.3. Prevent strong corrosive flames from directly spraying the sides and bottom of the crucible.4. Before use, it is necessary to heat bake and dry

Key elements that endanger the sales of graphite anode board

The key element of the sales of graphite anode plates Graphite anode board itself is a kind of conductive material. As a conductive, the name is the anode oxidation. Graphite anode plate is a type of electrolytic material. Compared with other anode oxide materials, there is no doubt its advantages. Simply speaking, the application field is wide, organic chemistry is stable, heat -resistant and heat transfer performance is better!Graphite anode boards occupy a large part of the annual sales of my company, which shows that the corporate graphite anode board products have a certain degree of recognition in the sales market. In addition, the sales of graphite anode oxide products have gradually soared.Each product is an industry that it uses, except for the graphite anode plate! It is necessary to improve the characteristics of the graphite anode plate itself and the scope of use. Graphite anode specifications in the field of electrolytic aluminum industry with large amounts and electropl

Talk about the hazard factors before the use of graphite.

Talking about the dangers of the storage hazards before the use of graphite crickets, the harm of the natural environment of Graphite to the performance of the natural environment is accumulated over time, and the harm is very large. Generally, it is stipulated that it is stored in a natural environment that is clean and irritable. Let's put it on the fixed wooden shelf to support the molten aluminum graphite. Difficulty in transportation, although graphite has very good thermal resistance, it is a very very easy to crush object. In the whole process of application and transportation, it is necessary to pay attention, and it should not make it a serious injury and other conditions.The value in the sales market is not very high, in fact, it is wrong to think so. Graphite looks very simple, it is commonly used in installing a variety of liquid state. However, in the industry lacks it, it will have a very large problem. Except for the industry's chemical manufacturing industry, it is no

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

Graphite powder is a very widely used industrial material

Graphite manufacturer's graphite powder is a very widely used industrial material. It is obtained by crushing and grinding through high -purity graphite. After screening, the type of graphite powder is key basis. The more the number of sieve networks, the thinner the particle size, the higher the price. In the past, the technical strength of our country could not be achieved, and high -end graphite powder depends on imports. However, at this stage, Chinese manufacturing companies have introduced overseas cutting -edge powder and grinding machines to produce fine graphite powder around the world. EssenceGraphite manufacturers' various graphite powder, moisturizing graphite powder, conductive graphite powder, nano -technology graphite powder, high pure graphite powder, graphite sieve nets are: 150 mesh, 425 mesh, 1000 mesh, 3000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 6500 mesh, 12500 mesh, 15000 mesh, etc. The

Several physical and chemical indicators that need to be understood when selecting graphite materials

Graphite is an allotrope of elemental carbon, where each carbon atom is surrounded by three other carbon atoms (arranged in a honeycomb like pattern with multiple hexagons) that are covalently bonded to form covalent molecules. Due to its excellent properties, graphite is used to make many materials. Below are several physical and chemical indicators that need to be understood when selecting graphite materials:1. Average particle diameter of the materialThe average particle diameter of a material directly affects its discharge condition. The smaller the average particle size of the material, the more uniform the discharge of the material, the more stable the discharge condition, and the better the surface quality. For forging and die-casting molds with low surface and precision requirements, it is usually recommended to use materials with coarser particles; For electronic molds with high surface and precision requirements, it is recommended to use an average particle size of 4 μ Mater
