Application of para-aramid fiber in composite filter paper material
The interface of the composite material is the bridge between the reinforcement phase and the matrix phase, which directly affects the stress transfer, damage accumulation and crack propagation between the two phases, thus determining the performance, failure behavior and application efficiency of the composite material. Para-aramid fiber reinforcement Composite materials have the properties of light weight, high strength, wear resistance, etc., and are widely used, becoming an indispensable basic material in high-tech fields.
The development and application of composite filter materials solves the limitations of the above filter cloth to a certain extent, and combines the advantages of woven knitted filter materials and non-woven filter materials, such as zhen ci felt, zhen ci felt filter material is a three-dimensional structure, High total porosity, many micropores, uniform distribution, small pore size and layered defense, can give full play to the filtering mechanism of screening, inertia, retention, diffusion, etc., high capture efficiency, low resistance, good air permeability, can achieve energy saving emission reduction effect. However, the composite filter materials currently on the market have complex production processes, high costs and relatively simple structures.
Membrane-coated filter material refers to a new type of filter material formed by coating a layer of film on the surface of machine/knitted base cloth or non-woven filter material by an appropriate method, so it has higher filtration efficiency and higher cleaning ability. It can better achieve surface filtration while ensuring a certain air permeability.
Frequently Asked Question
Do you have any question?
Ashless filter paper is used because it leaves no ash residue that could contaminate the dry precipitate sample and therefore affect its mass in the analysis.
The modified filter paper is proven to separate oil/water mixtures in acidic, alkaline, and salty environments. The filter paper is also applied to separate surfactant-stabilized oil/water emulsions successfully with high separation efficiency.
Ultrafiltration is the process of separating colloidal particles from solvent and soluble solutes by specially prepared filters. The filter should be permeable to all substances except the colloidal particles. Ultra-filter paper is used for this purpose.
