It features a design that significantly improves both surface area and compressive strength when compared to the standard Raschig ring. These rings offer exceptional resistance to acids and high temperatures, making them highly versatile for a wide range of industrial applications.&#10;&#10;Thanks to their robust structure, Ceramic Mini Lessing Rings resist corrosion from a variety of inorganic acids, organic acids, and solvents (except hydrofluoric acid). Additionally, they can perform reliably under extreme temperature conditions, whether high or low. This makes them an ideal choice for use in industries such as chemicals, metallurgy, coal gas, and oxygen production. These rings are commonly used in drying columns, absorption towers, cooling towers, and scrubbing towers.&#10;&#10;Produced through a rigorous calcination process lasting 24 hours, with a sintering temperature exceeding 1000\u00baC, Ceramic Mini Lessing Rings are inert, ensuring long-lasting performance in demanding environments.&#10;<\/p>\n<h4>Key Features &#038; Benefits<\/h4>\n<p>&#10;<\/p>\n<ul>&#10; \t<\/p>\n<li><strong>High Resistance<\/strong>: Excellent resistance to acids, alkalis, and heat, ensuring durability in harsh conditions.<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Large Flux<\/strong>: Capable of handling large flow rates, ensuring efficient operation.<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Faible perte de charge<\/strong>: Offers reduced pressure drop for optimized performance.<\/li>\n<p>&#10; \t<\/p>\n<li><strong>High Mass Transfer Efficiency<\/strong>: Ensures superior mass transfer, enhancing process efficiency.<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Robust Strength<\/strong>: Built to withstand significant compression forces, providing excellent structural integrity.<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Large Voidage<\/strong>: Ensures ample space for gas and liquid phases, maximizing efficiency.<\/li>\n<p>&#10;<\/ul>\n<p>&#10;<\/p>\n<h4>Wide Range of Applications<\/h4>\n<p>&#10;Ceramic Mini Lessing Rings are suitable for both high and low-temperature operations, making them an incredibly versatile solution for various industries, including:&#10;<\/p>\n<ul>&#10; \t<\/p>\n<li><strong>Industrie chimique<\/strong>: Used in drying and absorption towers.<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Metallurgy Industry<\/strong>: Ideal for applications requiring efficient heat and mass transfer.<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Coal Gas Industry<\/strong>: Excellent for gas treatment processes.<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Oxygen Production<\/strong>: Plays a key role in oxygen-producing systems.<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Environmental Solutions<\/strong>: Frequently used in scrubbing towers for air purification.<\/li>\n<p>&#10;<\/ul>\n<p>&#10;These ceramic rings excel in mass transfer applications and as heat transfer media in regenerative thermal oxidizers (RTOs), ensuring effective energy use and waste treatment.&#10;<\/p>\n<h4>Composition chimique<\/h4>\n<p>&#10;<\/p>\n<ul>&#10; \t<\/p>\n<li><strong>SiO2 + Al2O3<\/strong>: > 92%<\/li>\n<p>&#10; \t<\/p>\n<li><strong>CaO<\/strong>: < 1.0%<\/li>\n<p>&#10; \t<\/p>\n<li><strong>SiO2<\/strong>: > 76%<\/li>\n<p>&#10; \t<\/p>\n<li><strong>MgO<\/strong>: < 0.5%<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Al2O3<\/strong>: > 17%<\/li>\n<p>&#10; \t<\/p>\n<li><strong>K2O + Na2O<\/strong>: < 3.5%<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Fe2O3<\/strong>: < 1.0%<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Other Impurities<\/strong>: < 1%<\/li>\n<p>&#10;<\/ul>\n<p>&#10;<\/p>\n<h4>Physical Properties<\/h4>\n<p>&#10;<\/p>\n<ul>&#10; \t<\/p>\n<li><strong>Absorption de l'eau<\/strong>: < 0.5%<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Moh\u2019s Hardness<\/strong>: > 6.5 (on the Mohs scale)<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Porosit\u00e9<\/strong>: < 1%<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Acid Resistance<\/strong>: > 99.6%<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Specific Gravity<\/strong>: 2.3-2.4 g\/cm\u00b3<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Alkali Resistance<\/strong>: > 85%<\/li>\n<p>&#10; \t<\/p>\n<li><strong>Max.
