Ceramic films can now be sintered using very fine spherical particles. The pore size can be as small as 0.5 nm. Carbon fibers and ceramic films can also be made from very fine spun fibers.
The main components in the filtration process are the filter media, which largely determine the performance of the filter. In fact, from the simplest filter screen to the most complicated tower filter press, it is just a device that separates the suspended matter in a fluid (gas or liquid) by means of various semi-permeable materials. The nature of the filter media is its semi-permeable nature, which can be achieved by more and more methods.
The filter media can be made using various porous or semi-permeable materials, or made into this structure. The performance of the filter media is a combination of the properties of the manufactured material and its structure. Media types include:
Loose solid particles ("deep bed" media), whose shape is determined by the shape of the container; coarse porous plates, tubes or foams, usually made of compressed particles or fibers in the desired shape; made of natural or synthetic fibers Fibres, monofilaments, and multifilament fabrics; papers made of cellulose or fiberglass; felts and needle felts, made of natural or synthetic fibers; spunbonded synthetic nonwovens (spunbond, meltblown Method, flash evaporation method, electrospinning method; wire mesh or other metal media, made of metal plate or metal rod; filter cartridge, the component itself is not a filter media, but is made into filter media. These components can be made from a variety of materials, such as metals, plastics, and paper; polymeric films, including cellulose-based and synthetic; and various ceramic materials, including ceramic films.
In the past, there were almost only five types of materials in the filter media market, as well as barbed wire and filter cartridges. Now the use of other three materials (spinning nonwovens, films, and ceramics) continues to increase rapidly. Now the annual sales of these three materials are almost Occupy half of the entire filter media market (filter media and spare parts in original equipment). Polymer films account for one-third of the market for filter media, with spunmelt nonwovens approaching 15% and ceramics at about 7%.
The change in market share stems from the increasing demand for filtration accuracy in all separation processes, and the thin film just meets this requirement. Another technical driving force of the market is due to the increase of process temperature, and ceramics can well meet this requirement.
The pressure of environmental regulations is also an important factor in the driving force of these technological markets. The purification of fresh water and wastewater as well as the filtration of high temperature exhaust gases also require higher filtration performance to meet health and environmental regulations.
Of course, there are other market drivers in addition to these three points, but they are not just for the filter industry, such as population growth, the current economic recession, global warming, and the huge gap between rich and poor, and the resulting pressure to raise living standards.
One factor worth mentioning is the gradual emergence of an energy crisis, which forces filter press manufacturers and filter media manufacturers to provide systems that are as efficient as possible.
The filter media industry meets and continues to meet these driving forces through the development of a range of products: The use of large quantities of synthetic polymers as special-purpose filter media, especially for higher operating temperature polymers.
The expansion of polymer film applications, especially in microfiltration applications.
The development of inorganic film materials, especially ceramic films, also includes films made of metal, glass fiber, and carbon fiber.
The thin film media gradually becomes a multilayer composite structure: a thin layer of thin film material is attached to various base materials.
With the development of various spunmelt fiber materials, the fiber diameter also gradually decreases.
Ceramic filters that can withstand fairly high fluid temperatures are made of fibers rather than bulk materials.
In the past few years, the emergence of nanofibers may have brought the biggest changes to the filter media industry. Although nanofibers have been mistaken for all fibers less than 1 micron in diameter (ie, 1000 nm), many of today's media are made from 10-100 nm fibers. There is a certain relationship between the fiber diameter and the entrapped particles in the medium, that is, the finer the fiber, the finer the entrapped particles.
The diameter of the fiber is very important because fine filtration is used in many developing countries to improve the quality of drinking water in order to completely remove bacteria and microorganisms. The size of most microorganisms is around 100nm, so fine filtration can be used for the disinfection of drinking water. Fine filter media can purify natural water or even seawater at a lower cost, producing drinking water. This feature is of great significance to the filtration industry because it may make recycled wastewater another freshwater source.
Gas filtration also benefits from a finer filter media structure. Automobile cockpit air filtration is becoming one of the major markets for filter media. The development of synthetic media is increasingly important. In the past, two filtration units were usually installed, one for removing particulates and one for removing taste or color or odor, but now the two functions are combined into one material: the activated carbon particles are embedded in the fibers or the carbon fiber fabric is passed through High-temperature conversion to activated carbon fabrics. In addition to activated carbon, other materials can also be embedded to achieve different chemical changes. For example, inclusion of bactericides can be used to reduce pathogens.
Composite materials are the most important component of thin film media. The role of this material in other filter media is also increasingly important. Filter media are usually bonded together by two or more layers of composites, at least one of which is used to meet the filtration requirements and the other is used to provide the necessary mechanical strength. In sandwich media, two layers of spunbond material envelop and support the intermediate, finer layer of meltblown material (active filter layer).

Lip gloss:
1. Lip gloss can moisturize lips.
2. Lip gloss can play the role of decorating lips, making people look more colorful.
The difference between lip gloss and Lipstick:
1. The effect of lip gloss is more distinct and unique. Lipstick is low-key, generally used to moisturize lips, and its color is lighter.
2. The color of lip gloss is brighter and more changeable than that of traditional lipstick, but its durability is not as good as that of lipstick.
3. Lip gloss is rich in various highly moisturizing oils and glittering factors, which is bright, transparent, light and moisturized, and makes lips moist and three-dimensional after coloring. Lipstick has high color saturation and strong color hiding power. It is generally used to modify lip shape and color.
