Raw Materials and Processing Equipment of Spherical Graphite

Spherical graphite This graphite product is made with high-quality natural flake graphite. It also contains advanced processing technology that allows for graphite products to be produced with different levels of fineness and elliptical shape. 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 into small particles. Next, perform the de-angularization process, which will result in an ellipsoid, or spherical, shape. You can get the normal distribution for spherical graphite from the fine powder that is removed during this process.

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, adding too many products to the mix 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. The carbon content of spherical graphite raw materials is a key factor. The higher the carbon, the more expensive the raw materials. Additionally, the purification passes required to remove it will increase, increasing the equipment's wear and tear. Also, the overall cost of the equipment will rise. After practice and accumulation it contains 95%-96% of raw material, and the total cost is the lowest.

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 strong acids, the purification equipment must be resistant to acid and corrosion. Chemical purification must be completed at a particular temperature. The equipment should also have a high resistance to heat.

After the chemical reactions, impurities found in the spherical graphite are dissolved into the reaction solution. They can then be washed. 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 cannot be washed. While the centrifuge offers more washing power and a more effective wash, it also has 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, when the spherical carbonite has been washed and dried, it becomes substandard because of the inclusion of impurities. This is mostly evident in the unqualified indicators about carbon content or trace elements. Drying equipment such as the drying kilns and dryers in microwave ovens is also used.

Reasons for Spheroidization of Spherical Quartz Powder

What is spherical Quartz Powder?

Spherical Quartz Powder, also known by spherical Silica Powder, is an amorphous powder of quartz that has particles that are spherical in form and whose main constituent is silicon dioxide.

Spherical quartz is used primarily for copper clad laminations and epoxy mold compound fillers within large-scale integrated circuit packaging. However, it also has applications across high-tech areas such as aerospace and fine chemicals.

Why is Quartz Powder Spheroidized

1. The surface area of the ball has the lowest value, isotropy is high, film is well mixed with resin, resin is added in small amounts, fluidity is best, filling powder can be as high as 90%, and mass ratios can reach up to 90.5%. The filling speed of silica micropowder can be increased.

The filling rate for silicon micropowder is higher, but the plastic sealing compound's thermal expansion coefficient is lower. The thermal conductivity of the plastic sealing material is also lower, so it's closer to monocrystalline silicon. This will result in better performance.

2. The strength and stress concentration of the plastic sealing compound made from spherical dust is the lowest. The plastic sealing compound made of spherical is stronger than the one made from angular. It has a stress level of 0.6. When the spherical dust plastic sealing compound is used to encapsulate the integrated circuit chips, the yield is High. This makes it difficult to cause mechanical damage during transportation, installation and use.

3. Spherical powder's friction coefficient is low, so the mold wear is very minimal. The mold also has a long service-life. The service life of the mold is doubled when compared to angular powder. The cost of plastic sealing compound packaging molds is high. It is therefore necessary for some to be imported.

4. Silicon micropowder has the ability to strengthen epoxy resin. Spherical powder can also enhance this effect.

The Seven Methods for Preparing Spherical Alumina

Spherical Alumina Spherical alumina is produced by high temperature melting, high spherical rates, and high alpha-phase aluminum oxide content. This product has superior performance in rubber, plastic, and ceramic feedstock. Here is a summary of the methods for preparing spherical-grade alumina. Each method has its own characteristics.

Here are seven ways to prepare spherical aluminum:
1. Various sedimentation method
The precipitation process in homogeneous solutions is a crystal nuclear reaction. After that, the aggregation becomes greater and eventually from the solution from solution, it is usually unbalanced. But, if you lower the concentration of precipitant in homogeneous, even slowly Generation, then large numbers of microcrystals nuclei will be evenly produced. Finally, finely precipitated particle are uniformly distributed in the entire solution and a balanced state can be maintained for a long period of time. Method for average prediction. Al2 (SO4)3, Al (NO3) 3 & urea are used as raw materials. Under the conditions of an oil bath 98°C, the hydroxide produced by slow hydrolysis of Urea is precipitant. After calcination, the size and shape of the precursor particles can be altered by adjusting the proportion of SO422- to NO3-. Al2 (SO4) 3. The obtained colloid particles have a very good shape. This method was used in Al2(SO4) 3 and Urea as raw materials. The spherical (and hollow spherical) alumina powders were prepared under different conditions. A homogeneous precipitation process is possible if the precipitated particles obtained fall within the range for colloid particles. In addition to the conditions of SO42 - present, it is often difficult to finally form a glue of the globiosis in the gelation of sol particles to finally form a globiotype, so people think that this formation of sol-emulsion-condensation Gladle.
2. Sol-emulsion-gel method
This method is based on the sol-gel method. To obtain spherical powder particles from the oil phase, one uses the interface tension of both the oil and the water phases to form small spherical droplets. Aluminum hydrolysis produced the spheroidized powder of alumina. The aluminum hydrolysis process used acetonitrile as a solvent and the octanol (dissolved aluminum) accounted to 50%. The butanol and octanol from dispersed waters accounted respectively for 9% & 1%. Using hydroxypropylcellulose as a dispersant to obtain a spherical g-alumina powder having a very good spherical degree.
3. Drip method
The droplet method is used for binding the alumina sol to the oil layer (usually using petroleum oil, paraffin or mineral oil). The resulting spherical sol particle is then gelled in an alkaline ammonia solution. This is used to improve the sol-emulsion gel method.
4. Use templates
The template method controls the morphology during the production of spherical foodstock. The product is often hollow or has a nuclear-shell structure. The aluminum powder surface is used for simplifying the aluminum powder's surface. While the template method can be used to prepare an air spherical ball sphere, it has limitations. The preparation steps are more involved and require more effort.
5. Gas solve decomposition method
The aerosol decomposition process is usually based upon an aluminum salt. It uses the properties of aluminum alcohol and high-temperaturepyrolysis to make aluminum salt. Next, it uses phase transition to alkoxide gasify, then contact with watervapor. Finally, the high temperature dry or direct high temperatures are picked. This allows for a gas-liquid solid or gas-solid phase transition and forms a spherical powder of alumina. This method is based on complex experimental devices, which include atomizing moiety or reaction moieties.
6. Radio frequency induction plasma method
Radio frequency plasma treatment of alumina dust using radio frequency radiation. This plasma has high energy density and high heating power. It also allows for simple processing of material. The powder is free from any electrodes and therefore not contaminated by electrode evaporation. It is possible for purity to be maintained. Additionally, the plasma torch is heated rapidly and irregularly shaped particles of alumina are sprayed by the feed gas into the plasma torch. Droplets will quickly solidify, creating spherical particle.
7. Jet
The essence and structure of spinal alumina are formed quickly by surface tension. You can divide it into spray heat, spray drying, and spray melting Law, depending on the characteristics of phase transformation. AlCl3, Al2 SO4) 3, Al (NO3) 3 solution form small droplets through atomization. The process also requires a high thermal decomposition temperature of around 900°C. The aluminum salt solution is first mixed with ammonia to form an alkali sol. After that, the spherical product is sprayable at 150 to 240 deg C.

Spherical Quartz SiO2 Pulverization Methods
Flame melting method, plasma heating furnace technique, chemical synthesizer method, and hydrolysis are the most common methods to prepare sphere quartz 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 is also known locally as thermodynamic equilibrium plasma. The plasma's main features include the temperature of the local electrons (Te), ions (Ti), or gas (Tg). 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 : Silica sol emulsion at a specific temperature was treated using ammonia/ammonium bicarbose. The gel was then treated with acid to obtain hydrated, spherical, silica. Finally, the gel was refined and heat-treated in order 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.
