Was Ist Der Unterschied Molekularsieb 3a 4a 5a 13x

Was ist Molekularsieb?
Molekularsiebe sind synthetische kristalline Zeolithe, in denen die Atome in einem bestimmten Muster angeordnet sind. Im Inneren weist die Struktur viele Hohlräume auf, die durch kleinere Poren einheitlicher Größe miteinander verbunden sind. Diese Poren können nur Moleküle gleicher und kleinerer Größe aufnehmen und in die Hohlräume leiten, daher der Name Molekularsieb.Get more news about Molekularsieb 4a,you can vist our website!

Die Wasserdampfadsorptionseigenschaften unterscheiden sich stark von denen von Kieselgel. Molekularsiebe kann bis zu etwa 20 Gew.-% Wasser adsorbieren, bevor die relative Luftfeuchtigkeit der Umgebungsluft signifikant ansteigt. Jede weitere Erhöhung verursacht einen starken Anstieg der relativen Luftfeuchtigkeit.

Diese Eigenschaften ermöglichen es Molekularsieben, einen sehr niedrigen Taupunkt (-50°C für 10 Gew.-% adsorbiertes Wasser) aufrechtzuerhalten. Das Material hat auch die Fähigkeit, Wasserdampf schnell zu adsorbieren und ist in der Lage, eine hohe Adsorptionseffizienz bei hohen Temperaturen von bis zu 90°C aufrechtzuerhalten
Molekularsieb ist eine anorganische Aluminosilikatverbindung, die hohen Temperaturen standhalten kann und eine gute thermische Stabilität aufweist, die eine bequeme Regeneration bietet und viele Male wiederverwendet werden kann. Das Skelett wird nicht durch Mikroorganismen oder dergleichen zersetzt. Die Hauptkomponenten des Skelettteils des Molekularsiebs sind Silizium-Sauerstoff-Tetraeder und Aluminium-Sauerstoff-Tetraeder. Da die Wertigkeit von Aluminium 3 ist, ist die Wertigkeit eines Sauerstoffatoms im Aluminium-Sauerstoff-Tetraeder AlO4 nicht ausgeglichen, so dass der gesamte Aluminium-Sauerstoff-Tetraeder gebändert ist. Es hat eine negative Ladung. Um die elektrische Neutralität aufrechtzuerhalten, müssen positiv geladene Metallionen in der Nähe des Aluminiumoxid-Tetraeders vorhanden sein, um seine negative Ladung auszugleichen. Zwischen den positiv geladenen Metallionen und dem negativ geladenen Molekularsiebgerüst wird ein starkes elektrisches Feld erzeugt, das einen großen Einfluss auf die Adsorptionsleistung des Molekularsiebs hat. Die Adsorptionskapazität von Molekularsieben für polare Substanzen ist viel stärker als die von unpolaren Substanzen. Gleichzeitig besitzen sie durch die Einwirkung eines starken elektrischen Feldes für Substanzen mit Doppelbindungen oder großen π-Bindungen auch ein erhebliches Adsorptionsvermögen durch induzierte Polarisation. Im Allgemeinen gilt, je mehr Ladung das Kation trägt, desto kleiner der Ionenradius, desto stärker das erzeugte elektrische Feld, desto größer die Induktionswirkung auf Doppelbindungen und desto größer die Adsorptionskapazität für solche Substanzen.

Molekularsiebe werden als feste Adsorptionsmittel in der chemischen Industrie verwendet, und die adsorbierten Substanzen können desorbiert werden, und die Molekularsiebe können nach Gebrauch regeneriert werden. Wird auch zum Trocknen, Reinigen, Trennen und Rückgewinnen von Gasen und Flüssigkeiten verwendet. Seit den 1960er Jahren wird es als Cracking-Katalysator in der Erdölraffinerieindustrie verwendet, und jetzt wurde eine Vielzahl von Molekularsiebkatalysatoren entwickelt, die für verschiedene katalytische Prozesse geeignet sind. Es gibt zwei Arten von Molekularsieben: natürliches Zeolith und synthetisches Zeolith.â‘  Die meisten natürlichen Zeolithe werden durch die Reaktion von vulkanischem Tuff und tuffhaltigem Sedimentgestein in Meeres- oder Seeumgebungen gebildet. Derzeit gibt es mehr als 1000 Arten von Zeolitherzen, von denen 35 wichtiger sind, die häufigsten sind Klinoptilolith, Mordenit, Erionit und Chabazit. Hauptsächlich in den Vereinigten Staaten, Japan, Frankreich und anderen Ländern verbreitet, fand China auch eine große Anzahl von Mordenit- und Klinoptilolith-Lagerstätten, Japan ist das Land mit der größten Menge an natürlichem Zeolithabbau.â‘¡Da natürlicher Zeolith durch Ressourcen begrenzt ist, eine große Anzahl von synthetischen Zeolithen werden seit den 1950er Jahren verwendet.

Lithium grease, cleaning/deoxidizing, precision lubrication, oxidation/corrosion protection, excellent wear and pressure resistance, high dripping point, Temps; -40 to 260 C.
Copper particles: Contains copper particles assist in breaking up oxidation and corrosion. Copper is conductive. Other particles available; without particles, aluminum, quartz, graphite, graphite/quartz and Teflon.
Provides cleaning/deoxidizing and additional protection; Infused with DeoxIT Dx100L, which allows the fluid to mechanically bond to the metal surfaces. It cleans surfaces over time and coats and re-coats, even when surfaces are disturbed (vibration or mechanical movement). It is a non-conductive fluid that enhances conductivity. No other grease does this!
Ideal for applications in all industries; Audio/Video, Computers, Heavy Equipment, Automotive, Communications, Marine, Electrical, Energy, Photography, Security, Medical, Avionics, etc.
USES - ELECTRICAL & MECHANICAL: Antennas, battery terminals, Bearings, Buss bars, chain/sprockets, commutators, conductor rails, conductors, contactors, disconnects, doors/closures, drying & processing equipment, hatch closures, high amperage/high voltage, lifts, cranes, rack & pinion, robotics, power tools, relays & switches, slide bushings, O-rings/seals, worm gears, etc.

Whether you have a mechanical or electrical device, wouldn't you want to clean the surfaces while you lubricate? DeoxIT L260D Greases take care of both. The lithium grease is infused with our DeoxIT Dx100L fluid. It has the unique ability to lift off oxidation and corrosion from metal surfaces without harming surfaces. Unlike other aggressive chemicals, that remove layers of metal, possibly changing design specifications, DeoxIT L260D is gentle to the surface and works slowly to lift off contaminants. It keeps working until most if not all of the oxidation is lifted. The mechanical action of the device then displaces the contaminants away from the metal-to-metal connection. When you first apply the L260D Grease, the DeoxIT fluid molecularly bonds to the metal, sealing and lubricating the metal surfaces, so even when the grease eventually separates from the surfaces, the DeoxIT Dx100L fluid is still protecting the surfaces. DeoxIT Greases keep working when other greases stop!

Molecular Sieve 4A: A Key Player in Industrial Processes

Molecular sieves are a type of desiccant that have unique properties making them ideal for certain industrial processes. One such molecular sieve that is widely used is the 4A molecular sieve.Get more news about Molekularsieb 4a,you can vist our website!

The 4A molecular sieve, also known as zeolite 4A, is a type of aluminosilicate that has a three-dimensional pore structure. The '4A' refers to the pore size of this molecular sieve, which is approximately four angstroms. This specific pore size allows the 4A molecular sieve to selectively adsorb certain molecules while excluding others, based on their size.

One of the primary uses of the 4A molecular sieve is in the drying of gases and liquids. Its ability to adsorb water vapor is unparalleled, making it an excellent choice for applications that require extremely low humidity levels. For instance, in the natural gas industry, 4A molecular sieves are used to dry natural gas to prevent the formation of gas hydrates during transportation.

In addition to drying, the 4A molecular sieve is also used in size-selective catalysis. The uniform and small pore size of the 4A molecular sieve makes it an excellent catalyst for certain reactions where only small molecules are desired as the product.

The 4A molecular sieve is also used in the purification of gases. It can selectively adsorb contaminants based on their size, effectively purifying the gas. This is particularly useful in industries where high purity gases are required, such as in the semiconductor industry.

Despite its numerous industrial applications, the 4A molecular sieve is also environmentally friendly. It is non-toxic, chemically stable, and can be regenerated and reused, reducing its environmental impact.

In conclusion, the 4A molecular sieve is a versatile and valuable tool in various industrial processes. Its unique properties and environmental benefits make it an indispensable part of modern industry. As we continue to strive for efficiency and sustainability, the role of tools like the 4A molecular sieve will only become more important.
