Raw Materials and Processing Equipment of Spherical Graphite

/ / no Comments

Spherical graphite This graphite product is made with high-quality natural flake graphite. The graphite surface is modified by advanced technology to produce graphite products that have different finenesses and elliptical spherical shapes. Spherical graphite has the properties of high electrical conductivity and high crystallinity.
Spherical graphite The processing principle is: First, you need to pulverize natural flake graphite powder to a size that can be used for particle size. Then, you will need to de-angularize the material so it becomes ellipsoid, or spherical. The fine powder that is removed during this process can be separated and the normal distribution for spherical Graphite can then be obtained.
Selection criteria spherical graphite, raw materials

The particle size of the spherical graphite material should be suitable. Too fine a particle size results in higher costs. A smaller particle size can affect the yield of spherical graphite. Additionally, too many auxiliary items will increase the price of raw materials. Study have shown that it is easier to use spherical-graphite-making raw materials with a particle size between -100 and -100 mesh.

A very important aspect of spherical-graphite raw materials is their carbon content. Higher carbon contents mean higher costs for raw materials. The lower the carbon content, you will need to use more purification passes. In turn, equipment will wear faster and cost more. It is composed of 95%96% of the raw materials and has the lowest comprehensive cost after practice and accumulation.

Selection criteria for spherical-graphite processing equipment

The airflow vortex-pulverizer is more used in the spherical processing. This has both the performance for pulverization as well as the ability to de-angularize. It is important to consider the quality of the equipment when selecting grading equipment.

Graphite anode material for lithium-ion batteries must be at least 99.95%. Purification is an essential part of the production process. Chemical purification is the most common method of producing high-purity, spherical graphite. Since the chemical raw materials used in the production process are all strong acidic, the purification equipment must be both corrosion-resistant and acid-resistant. Chemical purification must be completed at a particular temperature. The equipment should also have a high resistance to heat.

After the chemical reactions, the impurities within the spherical graphite are dissolved into the reaction solution. Only then can the impurities be removed by washing. The most common washing equipment in this process is the filter press and centrifuge. The filter press offers many benefits, such as a higher recovery rate, low running material, low labor intensity and safety. However, it has a limited washing effect and can leave dead corners behind that can not be washed. While the centrifuge offers more washing power and a more effective wash, there are some drawbacks. Combining them works well.

The spherical Graphite after being washed is dried to remove moisture. It is also controlled below 0.5%. The most common problem with drying is secondary pollution. That is, after the spherical carbonite has been washed, it is dried to remove moisture. It is then dried to reduce the moisture level below 0.5%. Drying equipment such as the drying kilns and dryers in microwave ovens is also used.

What is Spherical Quartz SiO2 Powder?

/ / no Comments

Introduction to Spherical Quartz siO2 Powder Spherical powder of quartz Also known as Spherical silicon powder Amorphous quartz is a powder of amorphous silica. The individual particles are spherical. It is white in color, with uniform particle sizes, good transparency, chemical and thermal stability, safety, insoluble in water, and has high levels of safety.
Quartz powder in spheres It is used to make large-scale integrated circuit packaging. It is also used for high-tech applications such as aerospace, fine chemicals and daily cosmetics.

Physicochemical properties of Spherical Quartz SiO2 powder
Quartz powder in spheres It offers the benefits of a smooth surface and large specific area.
First of all, the powder is fluid and can be stirred with resin to form an even film. The resin can be added in small amounts, but the amount of quartz powder used for filling is substantial. The mass fraction can go up to 90.5%. The more quartz powder added to the mix, the lower its thermal conductivity. Additionally, the less thermal expansion coefficient the plastic sealing material has, the higher the performance of electronic components.
Second, the stress in spherical granules is less than that in angular granules. Also, the strength and stress concentrations of plastic sealants made from spherical Quartz powder are the lowest and highest. The yield is high when integrated circuit chips are encapsulated in spherical-powder plastic packing material. This makes it difficult to cause mechanical damage during transportation, installation and use.
Third, because the surface of the powder is smooth, it has a low friction coefficient, wear is minimal and molds can last for more than one time.

Spherical Quartz SiO2 Pulverization Methods
Flame melting method, plasma heating furnace technique, chemical synthesis and hydrolysis are the most common methods to prepare spherical powder.
1. Flame melting method Ball formation is achieved by using a high temperature flame gun that emits 1600-2000 high temperatures flame. The powder then absorbs heat from the flame and becomes molten. This heat is transferred to the powder inside, which is completely molten. Surface tension causes the object to always move to the stable condition, while the spherical shape is the most stable, in order to accomplish the product's purpose.
2. Plasma heating furnace method Hot plasma (also known as local thermodynamic balance plasma) is characterized by the presence of a local electron (Te), an ion(Ti), or a gas (Tg). These features are nearly identical. The thermal plasma category includes arc plasma, high-frequency and induction plasma.
High-frequency plasma melting is an efficient method of producing spherical quartz. The method uses moderate temperatures, stable control, high yield, and a high yield to achieve a higher level of spheroidization. Similar to the flame melting method, its principle and procedure are the same. The only difference is that the plasma generator is switched from a high-temperature heat source.
3. Chemical synthesis At a specific temperature, silica sol was treated with ammonia/ammonium bicarbose in order to obtain spherical gel. The gel was then treated with acid to produce hydrated spherical Silica. Finally, it was refined and heat-treated to obtain spherical Silica powder. It has low uranium and is easy for people to agglomerate.
4. Hydrolysis is a method : Add the liquid SiCl4 and deionized water with different dipersants at constant speed. The hydrolysate can then be stirred with a quartz rod at high speed. After washing, drying, and filtering, the hydrolysate has been dried, dehydrated to a constant weight in an oven at 100-200 degrees Celsius, and then transferred to the high temperature sintering furnace. High-temperature dehydroxylation at different temperatures can result in high-purity spherical quartz crystal powder.

Spherical alumina can be classified as thermal interface material, thermal-conductive engineering plastics and thermally conductive plastic sealing substances. The thermal interface materials can be used to IC packaging or electronic heat loss. These materials fill in any gaps caused by contact between the materials. This reduces the heat transfer resistance and improves heat dissipation. Inorganic thermal filler sphere alumina is common. Its thermal conductivity can reach 3042W/m K.

Ceramics using Spherical Allumina Powder
The properties of ceramics can be greatly affected by adding spherical amounts of alumina powder to their production processes. Low temperature brittleness in ceramics has a significant impact on their ability to be used for various purposes. For low-temperature plastic ceramics, you can use ceramic materials with spherical aluminum powder. Additionally, ceramics can be made tougher by using spherical-alumina. It can increase the ceramics' toughness by reducing the sintering temperatures and if the powder contains 5.0%.

As a polishing agent, use Spherical Allumina Powder
Spherical or flake-alumina alumina offers better fluidity and dispersion than conventional granular or flake. Because spherical powder abrasives are evenly distributed within polished products, there is no possibility for powder to accumulate in large quantities. The particle surface can also be smooth, which helps avoid scratches and improves polishing.

Spherical Led luminaire Use Both its catalyst and its transporter
High chemical activity is possible because of the large amount of unsaturated chemical bonding and catalytic activ centers that are found on the surface. Spherical Alumina offers the benefits of high chemical activity, low wear, and long service lives. It also boasts a large specific area. It is impossible to replace the performance and characteristics of the catalyst made of spherical aluminum with other materials.
