Modified silica sol refers to a type of colloidal solution where silica nanoparticles are suspended in a liquid medium, typically water. These silica nanoparticles are modified or functionalized with various organic or inorganic compounds to alter their surface properties and enhance their performance in different applications. The modification process can involve chemically bonding organic molecules to the surface of the silica particles, which can impart specific functionalities such as hydrophobicity, oleophobicity, or compatibility with certain polymers or solvents. Inorganic modifications may include incorporating metal oxides or other nanoparticles to enhance properties like catalytic activity or mechanical strength. Modified silica sols find widespread use in various industries such as coatings, adhesives, sealants, composites, and catalysts. They offer advantages like improved dispersion, adhesion, and compatibility, making them valuable additives in many formulations.
Hydrophobic silica is a type of silica material that has been chemically modified to repel or be resistant to water. This modification alters the surface properties of silica nanoparticles, making them less prone to interacting with water molecules. The modification process typically involves treating the surface of the silica nanoparticles with hydrophobic compounds, such as alkylsilanes or fluorosilanes. These compounds form a hydrophobic layer on the surface of the silica particles, effectively blocking interactions with water molecules. Hydrophobic silica finds numerous applications across various industries. For example, it is used as an additive in coatings, paints, and sealants to improve water repellency and durability. In the pharmaceutical and food industries, hydrophobic silica can be used as an anti-caking agent to prevent clumping in powdered products. Additionally, it is utilized in rubber and plastic composites to enhance their water resistance and mechanical properties.
Hydrophilic silica is a type of silica material that exhibits a strong affinity for water. Unlike hydrophobic silica, which repels water, hydrophilic silica readily interacts with and absorbs water molecules. The surface of hydrophilic silica nanoparticles is typically functionalized with hydrophilic groups, such as hydroxyl (-OH) groups. These groups enable the silica particles to form hydrogen bonds with water molecules, promoting their dispersion and solubility in aqueous solutions. Hydrophilic silica has various applications across industries. In the pharmaceutical and cosmetic sectors, it is used as an excipient in formulations to improve the dispersibility and bioavailability of active ingredients. In chromatography, hydrophilic silica is employed as a stationary phase for separating polar compounds. It is also utilized in coatings, paints, and adhesives to enhance their rheological properties and adhesion to substrates.
silica gel sand Silica sand is white particle, with main composed by SiO2. It s kind of new material to remove the impurity, oxidant, odor, color out of the crude oil by direct filtration. Well replace the complicated technology of acid, alkali etc. Advantage: After treated, the black oil was bleached into light transparent liquid, the acidity and color matches with National standard. The treated oil can be stored wit longer time without color returning, and stable quality with oxidant stability. These much saved the costs and time. With easier operation,better performance, it s widely recommended to oil refinery plants. Application: Usage: diesel refinery, deodorization, waste engine oil recycling, bio-diesel and other mineral oil refinery. Particle Size: 20-40 mesh, 20-80 mesh, 30-120 mesh, 40-160 mesh, 80-200 mesh, 200- 400mesh, negotiable.
