Hollow Glass Spheres Properties
OVERVIEW Hollow Glass Sphere Hollow Glass Beads(glass micro spheres):
What is hollow glass microsphere(glass micro spheres)?
Hollow glass microspheres(glass micro spheres), sometimes termed microballoons or glass bubbles, have diameters ranging from 10 to 300 micrometers. Hollow spheres are used as lightweight fillers in composite materials such as syntactic foam and lightweight concrete. The hollow glass bead(glass micro spheres) is a kind of specially processed glass bead, which is mainly characterized by smaller density and poorer thermal conductivity than glass bead. It is a new kind of micron-grade light material developed in the 1950s and 1960s. Its main component is borosilicate, with a general particle size of 10~250μm and a wall thickness of 1~2μm. Hollow glass beads are characterized by high compressive strength, high melting point, high resistivity, small thermal conductivity and thermal shrinkage coefficient, etc., and they are known as the "space-age material" in the 21st century.
Hollow glass microspheres, also known as bubbles, microbubbles, or micro balloons, are usually formulated from borosilicate - sodium salt glass mixtures and offer the advantages of low density, high heat and chemical resistance. The walls of glass microspheres are rigid and are usually about 10% thick of the diameter of the spheres. At present, spherical particles have a wide range of densities, from as low as 0.06g/ C3 to as high as 0.80g/ C3, with particle sizes ranging from 5um to 180um. The compressive strength of the hollow sphere is determined by the wall thickness of the hollow sphere and, as expected, the greater the density of the sphere, the higher the compressive strength.The lightweight hollow glass sphere is chemically stable, non-flammable, non-porous, excellent water resistance.

How are Hollow Glass Sphere Hollow Glass Beads (glass micro spheres)Produced? 
How do you make glass microspheres?
1. Glass powder method
The glass powder method uses pre-prepared glass powder containing gases such as SO3 to pass through the flame at the temperature of 1100-1500℃. At this time, SO3 and other gases dissolved in the glass powder overflow from the inside of the glass due to the decrease in solubility and the change in the atmosphere of the kiln. At the same time, the glass powder becomes spherical under high temperature due to the surface tension. The spillage gas is sealed in the spherical particles to form hollow glass beads.
2. Spray granulation method
Spray granulation method is made in advance with special auxiliary reagent (boric acid, urea, ammonium pentaborate) aqueous solution of sodium silicate, and then through the nozzle to the solution injection into the spray dryer, is expected to drop after drying to get a certain particle size of powder particles, the final will be powder particle heating foam-forming hollow glass beads.
3. The droplet method
The liquid drop method adopts the same raw materials as the spray granulation method. The raw materials are 500 copies of sodium silicate (M (SiO2): M (Na2O) =2), and the same amount of 10% ammonium perborate aqueous solution is added. After mixing evenly, the hollow glass beads are sprayed into the spray drying tower.
4. Dry gel method
The alkyl salt was added to dilute hydrochloric acid and decompose with water. After gelation, the gel was dried in two stages at 60℃ and 150℃ and then crushed by a ball mill. After grading, the dried gel powder was obtained, which was foamed in a vertical electric furnace at 1280℃ to prepare hollow glass microspheres.
 
Applications of Hollow Glass Sphere Hollow Glass Beads:

Lightweight Filler Material

Hollow glass beads(glass micro spheres) are widely used as lightweight filler materials in plastics, rubber, coatings and other products due to their light and low-density characteristics. These products usually need to reduce weight cost, improve performance, etc.; hollow glass beads can meet these requirements. In plastic products, hollow glass beads can be used as reinforcing filler material to enhance the products' strength, rigidity and weather resistance. In rubber products, hollow glass beads can be used as reinforcing filler material to improve abrasion resistance, tear-resistance and aging resistance. In coatings, hollow glass beads can be used as pigment filler to improve the covering power and transparency of coatings.

 

Heat Insulation Material

As hollow glass beads(glass micro spheres) have good thermal insulation properties, they can be used to manufacture thermal insulation materials, such as glass wool, vacuum insulation boards and so on. These materials are lightweight, efficient, environmentally friendly, and widely used in construction, aerospace, and other fields. In the field of construction, hollow glass beads can be used to manufacture lightweight thermal insulation and heat preservation boards, which have excellent thermal insulation and heat preservation effects and can effectively reduce the energy consumption and temperature fluctuations of buildings. At the same time, this kind of board also has the advantages of lightweight and environmental protection, which can reduce environmental impact. In the aerospace field, hollow glass beads can be used to manufacture thermal insulation materials for aircraft shells and thermal protection materials for spacecraft. These materials need to maintain stable performance in a variety of complex environments, such as high temperature, low temperature, vacuum, etc. Hollow glass beads are able to meet these requirements due to their unique structure and properties.

 

Electromagnetic wave shielding materials

Hollow glass beads(glass micro spheres) have good transmittance to electromagnetic waves and can be used to manufacture electromagnetic wave shielding materials, such as electromagnetic wave absorbing materials and electromagnetic wave protective clothing. These materials have important application value in electronic equipment, aerospace and other fields. In the field of electronic equipment, hollow glass beads can be used to manufacture electromagnetic wave-absorbing materials and electromagnetic wave protective clothing. Electromagnetic wave-absorbing materials can absorb electromagnetic waves and convert them into heat or other forms of energy, reducing the harm of electromagnetic waves to the human body. Electromagnetic wave protective clothing can protect workers from electromagnetic wave hazards, especially when working in high-frequency electromagnetic fields, and they need to take additional protective measures.

 

Reinforced Composites

Hollow glass beads(glass micro spheres) can be used as reinforcement in composite materials such as glass fiber-reinforced plastics and carbon fiber-reinforced resins due to their high strength, high rigidity and good chemical resistance.

Drug Carrier

A drug carrier is a substance that can slowly release drugs into the human body. A drug carrier needs to have good biocompatibility and safety at the same time; the release rate and concentration of the drug also need to be precisely controlled by hollow glass beads as a drug carrier has the unique advantages of spherical shape and smooth surface characteristics that make it an ideal choice of drug carriers through the drug encapsulated in the hollow glass beads can be realized on the slow release and controlled release of the drug this kind of drug carrier can be used to achieve the slow release and controlled release of the drug. By encapsulating the drug in hollow glass beads, it can realize its slow waiver and controlled release. This kind of drug carrier has a significant application value in the field of drug delivery and controlled release of drugs.

 

Catalyst carrier

A catalyst is a substance that accelerates the reaction speed in a chemical reaction. Usually, it needs to be evenly dispersed in the reactants to play the best role. Hollow glass beads can be used as a catalyst carrier due to their high surface area and good chemical stability. Loading the catalyst on hollow glass beads can improve the dispersion and stability of the trigger and thus enhance the efficiency of the catalytic reaction. This catalyst carrier has essential application value in chemical and environmental protection.
