A separator is a permeable membrane placed between a battery's anode and cathode. The main function of a separator is to keep the two electrodes apart to prevent electrical short circuits while also allowing the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell.
Bagged Salt is a kind of chemical product applied to the melting of ice. It has important applications in some industrial places and environmental fields. The bagged salt can reduce the freezing point of snow and thus melt the snow layer faster.
The Azoxystrobin market is one type of funbicide of Strobilurin. Azoxystrobin is a systemic, broad-spectrum fungicide that was first introduced in 1998. It inhibits spore germination and is used on grape vines, cereals, potatoes, apples, bananas, citrus, tomatoes and other crops.
Architectural acoustics (also known as room acoustics and building acoustics) is the science and engineering of achieving a good sound within a building and is a branch of acoustical engineering. Architectural acoustic panel is used to reduce noise and control sound in many different spaces. They come in a large variety of sizes, types and colors.
Anti-fog coatings are a type of hydrophilic coatings which contain polyvinyl alcohol in their formulation. These coatings help disperse small droplets of fog formed due to the condensation of water and are therefore also known as non-mist coatings. Anti-fog coatings are transparent, abrasion-resistant, and durable in nature; and thus do not degrade even after extensive usage.
It is ideally suited for surfaces where prevention of fogging and frosting is needed. The coating may be used on sports and safety goggles, glasses, face shields, respirators, outdoor signage, camera heads, environmental enclosures, windows, mirrors, windshields, displays, and other applications where fogging needs to be mitigated.
The chemical composition of the aluminium-scandium master-alloy is 2% scandium and the balance is 99.7% aluminium. The master alloy is used to add scandium to Al-Mg-Zr containing alloys, which are used in the form of sheet and plate. These sheets and plates are mainly used by aircraft manufactures. The scandium content in the aluminium sheet and plate varies from 0.2-0.4% scandium.
Aluminium scandium containing alloys combine high strength, ductility, weld-ability, improved corrosion resistance and a lower density (as a result of the magnesium in the alloy). The combination of all these properties makes aluminium-scandium containing alloys extremely suitable for aerospace industry.
Aluminium powder is powdered aluminium. This was originally produced by mechanical means using a stamp mill to create flakes. Subsequently, a process of spraying molten aluminium to create a powder of droplets was developed by E. J. Hall in the 1920s. The resulting powder might then be processed further in a ball mill to flatten it into flakes for use as a coating or pigment. Aluminium powder is non-toxic and is not harmful unless injected directly in a major blood vessel such as the aorta Aluminium powder, if breathed in, is not particularly harmful and will only cause minor irritation. The melting point of aluminum powder is 660 °C.
Alloy steels are made by combining carbon steel with one or several alloying elements, such as manganese, silicon, nickel, titanium, copper, chromium and aluminum. These metals are added to produce specific properties that are not found in regular carbon steel. The elements are added in varying proportions (or combinations) making the material take on different aspects such as increased hardness, increased corrosion resistance, increased strength, improved formability (ductility); the weld ability can also change.
Aliphatic Isocyanates (ADI) are specialty intermediate chemicals used primarily to make polyurethane coatings, adhesives & sealants and elastomers. They belong to the family of isocyanate which contains R–N=C=O group, along with alicyclic isocyanate and aromatic isocyanate.
Hexamethylene diisocyanate (HDI), isophorone diisocyanate (IPDI) and methylene dicyclohexyl diisocyanate or hydrogenated MDI (H12MDI) is three common types of aliphatic diisocyanates.
