Expanded filtration material is a type of material that boasts a porous structure, lightweight design, high strength, and excellent adsorption properties, making it widely applicable in various filtration fields. Its raw materials and technical specifications can vary depending on the specific material used and its intended application. Below is a general introduction to the raw materials and technical specifications of expanded filtration material:
I. Raw Materials
The raw materials for expanded filtration material are diverse and include the following:
Glass Fiber: Glass fiber is a common raw material for expanded filtration material. It is known for its high temperature resistance, corrosion resistance, excellent dimensional stability, and high tensile strength. In particular, E-glass (electrical grade glass) fiber exhibits superior corrosion resistance and folding endurance.
Polytetrafluoroethylene (PTFE): PTFE films are often used as coating materials for glass fiber filter media to enhance surface smoothness, water repellency, breathability, and chemical stability. PTFE emulsions and silicone oils are also commonly used as binders in the production of expanded glass fiber cloth.
Polyurethane: Polyurethane expanded material is a porous material made from polyurethane, offering elasticity and abrasion resistance, suitable for specific filtration requirements.
Polypropylene: Polypropylene expanded material has good corrosion resistance and high-temperature resistance, making it suitable for applications such as chemical storage containers and air filters.
Silicate: Silicate expanded material possesses excellent adsorption properties and chemical stability, commonly used in the manufacture of catalysts and desiccants.
Ceramic: Ceramic expanded material stands out for its exceptional high-temperature resistance and chemical stability, suitable for filtration needs in high-temperature environments.
II. Technical Specifications
The technical specifications of expanded filtration material vary based on the material type and application, but generally include the following aspects:
Density: Expanded filtration materials typically have a low density, which contributes to their adsorption performance and breathability. The specific density value depends on the material type and production process.
Compressive Strength: Compressive strength measures a material's ability to resist deformation under pressure. Expanded filtration material must possess sufficient compressive strength to maintain its shape and integrity during use.
Moisture Absorption: Moisture absorption refers to a material's ability to absorb water. For filtration materials, low moisture absorption helps maintain filtration efficiency and performance stability.
Temperature Resistance: Expanded filtration material must maintain stable performance within a certain temperature range. The temperature resistance varies depending on the material's thermal and chemical stability.
Breathability: Breathability refers to a material's ability to allow gas to pass through. Good breathability is a fundamental property of filtration materials. The specific air permeability value depends on the material's pore structure and pore size.
Dimensional Stability: Expanded filtration material must maintain dimensional stability during use to prevent changes in filtration effectiveness due to dimensional variations.
