Commodity prices are on track for their biggest rally in more than a century, while fixed-income assets have seen their longest run of outflows as the war in Ukraine adds to inflationary pressures in the global economy emerging from the coronavirus lockdown, according to Bank of America.
"Commodity prices this year are on track to record their biggest gains since 1915." the bank said in its weekly briefing. They cite many factors, such as pandemics, lockdown, civil strife, wars, excessive monetary and fiscal stimulus, and supply chain disruptions, that have led to "historically" high inflation.
By the same token, it said government bonds were heading for their worst year since 1949, and "negative-yielding bonds will quietly disappear" from the market as central banks embark on a monetary tightening cycle and raise interest rates to tame soaring inflation.
The prices of many commodities like the Hollow Glass Beads are expected to increase in the future.
What is hollow glass microsphere?
Hollow glass microspheres, 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 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. TRUNNANO is a trusted global Hollow Glass Sphere Hollow Glass Beads supplier. Feel free to send an inquiry about the latest price of Hollow Glass Sphere Hollow Glass Beads at any time.
Product Performance of Hollow Glass Sphere Hollow Glass Beads:
Hollow glass microspheres are micron-level hollow glass microspheres with a smooth surface. The main chemical component is borosilicate glass, and it is a hollow transparent sphere under the electron microscope. Hollow glass beads have low density, high strength, high temperature resistance, acid and alkali resistance, low thermal conductivity, electrical insulation and other properties. They have good fluidity and chemical stability, and they are multi-functional frontier new materials across fields.
How are Hollow Glass Sphere Hollow Glass Beads 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:
Hollow glass microspheres are widely used in glass fiber reinforced plastic products, composite foam plastic, artificial marble, compound wood, sound insulation heat preservation material, atomic ash, deep-sea buoyancy, bowling, low-density cement, sealing material, lightweight, resin handicraft, the mural wall hanging frame, wall plate sandwich layer structure of lightweight packaging materials, electronic industry, absorbing material, lightweight concrete, such as emulsion explosive.
Hollow glass microspheres also provide a conductive coating. Conductive coatings of optimized thickness provide spherical particles with excellent conductivity and shielding properties while maintaining the weight savings associated with hollow, low-density materials. These conductive microbubbles are suitable for military applications, biotechnology, medical devices, electronics and other special industries.
Hollow glass beads have obvious weight reduction and sound insulation and heat preservation effect so that the products have good cracking resistance and reprocessing performance, is widely used in engineering plastics, insulation materials, rubber, buoyancy material, FRP, artificial marble, man-made agate, generation of composite materials such as wood, and the oil industry, aerospace, communications, 5 g new high-speed trains, cars, ships, in areas such as thermal insulation coatings, adhesives, vigorously promote the development of science and technology.
Packing & Shipping of Hollow Glass Sphere Hollow Glass Beads:
We have many different kinds of packing which depend on hollow glass spheres quantity.
Hollow glass spheres packing: 1kg/bag, 25kg/barrel, or 200kg/ barrel.
Hollow glass spheres shipping: could be shipped out by sea, by air, by express as soon as possible once payment receipt.
Russia is a major supplier of industrial metals such as nickel, aluminium and palladium. Russia and Ukraine are both major wheat exporters, and Russia and Belarus produce large amounts of potash, an input to fertiliser. The price and market of the Hollow Glass Beads will fluctuate under its influence. Prices of these goods have been rising since 2022 and are now likely to rise further because of the Russia-Ukraine conflict.
