Nano in industrial filters
Nano filters in various industries can significantly reduce factory emissions.
Nano:
Filtration is a mechanical or physical process in which solid suspended solids are extracted from a fluid. The basis of separation in this method is the difference between solid and fluid size and the use of external force to pass the material through a lattice membrane. It is natural that the smaller the pore size of this membrane, the more it is able to separate particles from the fluid phase. This process is used in many industries. The production of membranes with pores at the nanoscale can be very important. Today, industrial filters are used to separate dust particles or particles from air or fuel and oil and other items. These filters are not able to separate fine particles with dimensions less than 500 nm and reach the saturation limit in a short time. Nanofibers will have great potential for application in the gas and liquid filtration industry due to their special properties. In this regard, by adding a layer of nanofibers to the filter paper surface and thinning the fiber diameter and also reducing the thickness of the filters, a specific filter surface with a higher number of porosity with smaller porosity dimensions is obtained. These will increase the life of the filter and separate the finer particles. Filters with these nanofibers have a low base weight, high air permeability and small pore dimensions. Filtration operations in this type of filters are performed on the surface, and in fact with nanotechnology, the filtration operation is changed from depth to the surface, and this leads to better permeability and longer filter life.
Nano in air filter:
The car air filter is used to protect the engine and prevent engine parts from being damaged by dust particles, pollution and other harmful particles in the air. This product is used in different shapes for different types of cars. The latest development in the filter industry is the entry of nanotechnology into this field. With this technique, the surface of cellulosic or synthetic fibers (usually 10 to 30 micrometers in diameter) is covered with a layer of nanofibers (usually 50 to 400 nanometers in diameter). There are two different ways of separating particles in the filter paper structure:
Nano in oil filter
Adhesives are one of the most widely used materials in our daily lives. This product is widely used in various industries. Industrial manufacturers of oil filters use glue to assemble various filter components, such as attaching filter paper to a frame or installing filter washers. These manufacturers have been using plastisols as adhesives and molds for many years. These materials do not need to be mixed or added to other components and can be pumped directly through a cylindrical tank. These materials are also able to withstand high temperatures for at least ten minutes. One of the problems of this type of adhesives is their low viscosity, which limits their use and reduces the speed of working with them. Adding suitable nanoparticles to adhesives can improve this property; While it does not have a negative effect on other features.
Nano in fuel filter:
Fuel filter paper is one of the essential consumables of the car. Standard fuel filter paper has the ability to absorb fine particles and microscopic impurities in car fuel. In new cars, the fuel filter is placed inside the fuel tank and its replacement must be done by a relevant specialist. Dirty fuel filter paper can clog the injector and cause serious damage to the car engine. Existence of fuel filter has a great impact on better engine performance and optimal fuel consumption. Fuel for passenger cars and heavy vehicles includes gasoline and diesel. Fuel filter paper is used in the form of gasoline filter paper and diesel filter paper in cars. The fuel consumed by vehicles may be mixed with impurities during the transfer process to fuel supply stations. These impurities, whether water or impurities and small and large particles, can cause serious and costly damage to the car engine. For example, if a combination of fuel and water enters the fuel tank, it will cause rust inside the tank. Also, smoke coming out of the exhaust, improper performance and reducing the power of the car engine and erosion of the internal parts of the fuel system are other signs of water entering the car fuel tank. The entry of impurities in the form of fine and coarse particles also causes erosion of fuel system components. Since the car fuel system and its components have a high sensitivity, so for purifying the fuel entering the car tank, two stages of passing through the filter and fuel filter paper have been considered. In the first stage, gasoline is purified by a strainer located in the pump. In the next step, gasoline passes through the fuel filter paper and impurities are absorbed by the filter paper. In this way, the gasoline is refined and enters the fuel tanks without foreign particles. The use of nanotechnology and its papers can play an important role in better performance and less erosion and rust in different parts of the tank.
