What are the Industrial Applications of Fumed Silica?

Fumed silica, also known as pyrogenic silica, consists of microscopic droplets of amorphous silica which are fused into branched, chainlike, three-dimensional secondary particles. The substance is composed of submicron-sized spheres which are 40-60% fused into short chains and is heavily chained. Bee Chems is best fumed silica suppliers and manufacturer in the world. Bee Chems produces all grades of fumed silica at very best quality price and in good quantity. The powder has very low bulk density and large surface area which makes it suitable for use in a multitude of applications including:

1. Reinforcement of Elastomers

Many companies use fumed silica as a reinforcing filler in elastomers. Using the chemical, you can see an improvement in their mechanical properties, such as tensile strength, elongation at break and tear resistance. The substance can also help control the influence of temperature on mechanical properties.

2. Toner

Fumed silica can improve the flow characteristics and charge stability of toners, as well as performance enhancements, such as improved resolution and print quality of laser beam printers or plain paper copiers. The substance can also improve the flowability of the dry toner and to minimize the electrostatic charge variation of dry toner.

3. High Temperature Insulation

Fumed silica has extraordinary temperature insulation properties. This is because amorphous silicon dioxide has a very low solid-state conductivity. The space between the particles of the chemical is in the same order as the mean free path dimensions for oxygen and nitrogen molecules. Thermal conductivity drops with decreasing average primary particle size of fumed silica.

4. Adsorbent

With high specific surface area, fumed silica can adsorb gaseous, liquid or solid materials more than any other chemical available on the market. The substance will preferably adsorb those materials which can form hydrogen bond linkages with the silanol groups on its surface or which can interact on an acid-alkali basis.

5. Other Industrial Applications

Fumed silica can be used as an anti-caking agent in powders. The chemical serves as a desiccant and is also used in cosmetics for its light-diffusing properties. The substance is also used as a light abrasive in products like toothpaste. It is also used in the production of cat litter box filler.

If you’re looking to buy commercial grade fumed silica, Bee Chems is your place to go. In addition to fumed silica, the company also offers old box resins, precipitated silica, Co2 absorbent, soda lime absorbent, saffron, lithium hydroxide and various others.

Characteristics and Applications of Activated Alumina

Activated alumina is a porous form of aluminum oxide that is used for various industrial applications. The chemical is mainly used to dry gases which is vitally necessary for safe transportation of volatile gases. Activated alumina is an adsorbent not an absorbent meaning water can be drawn into the pores of activated alumina. Here are some of the vital applications of activated alumina:

1. Catalyst applications

Activated alumina is used for the adsorption of catalysts in polyethylene production, hydrogen peroxide production, as a selective adsorbent for many chemicals including arsenic, in sulfur removal from fluid streams. It is also used as an inert carrier, or substrate for other catalysts.

2. Adsorbent

Activated alumina is a highly effective adsorbent in both gas and liquid applications. This way, the chemical is employed by numerous industries for targeted removal of components from other media. The chemical is well-known for its use in water filtration applications. It is also used in the removal of a variety of other contaminants, including arsenic, lead, and sulfur.

3. Desiccant

Activated alumina is used as the water in the air sticks in between the tiny passages as the air passes through them. The water molecules become trapped so that the air is dried out as it passes through the filter. This process is reversible as when the substance is heated to ~200 °C, it will release the trapped water. This process is called regenerating the desiccant.

4. Defluoridation

Fluorine in water can cause a lot of issues for people. Defluoridation is the removal of fluorine from water. Activated alumina is also widely used to remove fluoride from drinking water. Activated alumina filters can easily reduce fluoride levels from 10 ppm to less than 1 ppm.

5. Other Applications

In high vacuum applications, activated alumina is used as a charge material in fore-line traps to prevent oil generated by rotary vane pumps from back streaming into the system. Its mechanical properties and non-reactivity in the biological environment allow it to be a suitable material used to cover surfaces in friction in body prostheses.

If you’re looking for top grade Activated Alumina, Bee Chems is your place to go. In addition to alumina-based products, the organization also provides colloidal silica, calcium silicate, silica gel-sorbogel, carbex, molecular sieves and various others.

Soda Lime Absorbents (CoxOut™): Characteristics and Applications

Soda lime absorbents (CoxOut™) are absorbers used for removal of Carbon Dioxide (CO₂) and other acid gases. This chemical absorbent mainly contains calcium hydroxide (Ca(OH)₂) and water. The calcium hydroxide reacts with CO₂ to form calcium carbonate which is retained within the absorbent bed. The absorbents are commonly used in breathable and industrial gas applications. The absorbents convert gaseous carbon dioxide (CO₂) to solid calcium carbonate (CaCO₃) which is retained within the substance, thereby removing carbon dioxide from the gas stream. The substance is used in a plethora of applications including:

• In diving rebreathers and saturation dive systems for commercial subsea applications
• In mining industry for closed circuit breathing apparatus and mine refuge chambers
• For removal of carbon dioxide in hyperbaric oxygen treatment chambers
• In submarine atmosphere purification and collective protection for the military
• For compressed air purification, petrochemical (acid gas removal),CO₂ abatement
• To Remove expelled carbon dioxide due to respiration in anesthetic systems
• For removal of carbon dioxide in fire safety apparatus, and mine rescue equipment

There are thousands of suppliers of soda lime absorbers in the market. You need to choose a certified supplier for ethylene absorbers and that can be a challenging task. Therefore, if you are looking to buy soda lime absorbent, Bee Chems is your best choice.

The company provides its soda lime absorbent under the name CoxOut™. For shipping, they provide the absorbers in containers of 500gram, 4.5 kg. Keg, 20 kg. Pail, 35/50 kg. drums. They provide the chemicals in various grades and two types, pink to white and white to purple.

Ethylene Absorbers from Bee Chems Extend the Shelf Life of Fruits, Vegetables and Flowers in a Packaged or Bulk Environment

Ethylene absorbers are made from naturally occurring zeolites that are used to remove unwanted ethylene gas through the oxidation process. The products can preserve the quality and freshness of the produce while in transit or in storage. The absorbers can extend the shelf life of fruits, vegetables and flowers in a packaged or bulk environment.

The products have been proven to slow down fresh produce decay, to prevent mold, rot, and remove odors. Ethylene absorbers are especially important when transporting products that emit high levels of ethylene, are ethylene sensitive or prone to molds. The absorbers are used to protect various food products such as avocados, apples, broccoli, carnations, citrus, kiwi, and many more.

Ethylene absorbers have a plethora of advantages including:

• Eliminate mold, decay, discoloration, wilting, softening, scald, loss of crunch
• Used during post-harvest handling to slow down the ripening process of fruits, vegetables and flowers
• Used during domestic and international shipments via ocean, truck, rail and air
• Can be disposed of as normal waste as they are non-toxic and chemically inert
• Increase the shelf life of the produce is increased substantially
• Improve produce appearance, texture, and nutritional quality
• Eliminate any unpleasant odors
