RD activated clay is an inorganic mineral adsorbent with strong adsorption properties, mainly made from bentonite and processed through a series of refined processing methods. It usually appears as a white or grayish-white powder, odorless and tasteless, with good fluidity, adsorption performance, and chemical stability. 
　　Features and Advantages 
　　● Strong adsorption performance: Activated clay has a developed pore structure and a large specific surface area, exhibiting strong adsorption capacity for pigments, colloids, odorous substances, and various organic impurities in oils and fats. In the oil refining process, it effectively removes pigments and impurities from oils and fats, lightening the color, improving the quality, and achieving high adsorption efficiency and speed. 
　　● Good chemical stability: At room temperature, it does not react violently with acids, alkalis, and other chemicals, exhibiting good chemical stability. It maintains stable performance under different process conditions, ensuring consistent and reliable adsorption effects. 
　　● High decolorization rate: It excels particularly in oil decolorization, effectively removing pigments from various animal and vegetable oils and fats (such as rapeseed oil, soybean oil, peanut oil, palm oil, etc.). The decolorization rate can reach over 90%, resulting in clear and bright oils that meet the standards of high-quality oils. 
　　● Excellent filtration performance: Activated clay particles are uniform, forming a loose filter cake structure during use with good air permeability and low filtration resistance, facilitating filtration operations, improving production efficiency, and reducing filtration costs. 
　　● No secondary pollution: The product itself does not contain toxic or harmful components and does not introduce new impurities or harmful substances into the treated materials during adsorption, ensuring the safety of the treated products. After proper treatment, the used waste clay can be recycled or disposed of safely, minimizing environmental impact. 
　　● Wide applicability: It is not only suitable for decolorization and refining in the oil industry but also widely used in various fields such as chemicals, environmental protection, food, and pharmaceuticals, meeting the adsorption and purification needs of different industries. 
　　Application Areas 
　　● Oil industry: It is a key auxiliary agent in oil refining, widely used in the decolorization, deodorization, and purification of vegetable oils, animal oils, and mineral oils. It effectively removes pigments such as chlorophyll and carotenoids, as well as phospholipids, soapstock, and odorous substances, improving the quality, stability, and shelf life of oils and fats to meet edible or industrial use standards. 
　　● Chemical industry: In chemical production, it can be used for the refining and purification of various organic compounds, such as decolorizing and purifying organic solvents like benzene, toluene, and xylene to remove impurities and colored substances. It can also be used for refining chemical products (such as lubricating oil, paraffin wax, and fatty acids) to improve product purity and quality. 
　　● Environmental protection field: It can be used in wastewater treatment to adsorb and remove organic pollutants and heavy metal ions from wastewater, reducing the pollution level. In waste gas treatment, it can adsorb odorous substances and some harmful gases from waste gas to purify the air environment. 
　　● Food industry: In addition to oil refining, it can also be used for decolorization and purification of foods such as sugars, wines, and juices. For example, in sugar production, it can remove pigments and impurities from sugar liquid, improving the purity and whiteness of sugar. In juice processing, it can remove turbidity and pigments from juice, making the juice clear and transparent. 
　　● Pharmaceutical industry: In the purification and refining of pharmaceutical intermediates, it can be used to remove impurities and colored substances, improving the purity and quality of pharmaceutical products to ensure the safety and effectiveness of drugs. 
　　Product Specifications 
　　Various specifications of activated clay products can be provided according to customer needs, mainly including the following: 
　　● Particle size: Common particle size specifications include 1-2MM particles, with a 200-mesh pass rate ≥95% and a 325-mesh pass rate ≥90%, adjustable according to customer's specific process requirements. 
　　● Decolorization rate: Depending on the application scenario, the decolorization rate of the product can be divided into ordinary grade (decolorization rate 80%-85%), first-grade product (decolorization rate 85%-90%), and superior grade (decolorization rate ≥90%).
