In the wave of the new materials industry, powders... “ Purity ” and “ Particle size distribution ” It almost determines the success or failure of a product. From conductive silver pastes and carbon nanotubes to silicon-carbon anode materials for lithium batteries, as well as key functional powders such as high-purity alumina, silicon carbide, and silicon nitride, cleanliness and dispersibility at the particle level have become core indicators of industrial competitiveness. In this stage, the importance of filtration and classification processes is being redefined.

Over the past decade, China’s powder manufacturing companies have largely relied on conventional filtration equipment such as plate-and-frame, bag-type, and centrifugal filters. Although these devices are well-established, they generally face challenges when handling sub-micron or even nano-sized particles—including low efficiency, thick filter cakes, difficult regeneration, and significant fluctuations in filtration accuracy. As industries such as new energy, electronic pastes, semiconductor packaging, and ultra-hard materials continue to rise, the limitations of traditional filtration machines have become increasingly apparent.

It is precisely at such an industrial juncture that... Xiamen Xiadis Filter Materials Technology Co., Ltd. The newly launched nano-micron powder filtration machine is becoming the link. “ High-purity raw material ” With “ High-performance materials ” The key bridge.

I. From Tradition to Innovation: Powder Filtration “ Critical point ”

The working principle of conventional filters is primarily based on macroscopic pores and mechanical interception; the pore size of filter cloths typically ranges from... 10 ~ 50 Between micrometers. For particle sizes smaller than 1 Micron-sized fine powders, colloids, and nano-aggregates often appear. “ Reveal ” or “ Pasted cloth ” Two extreme phenomena, the result is:

• The filtration time is too long, making it difficult to match the production takt with the high-end material line.

• The filter cake has a high moisture content, causing drying energy consumption to soar.

• The fine powder loss rate is high, reducing the yield.

New nanomicro-powder filtration machine On this basis, a systematic reconstruction is carried out to achieve controllable filtration of nanometer- and micrometer-sized particles. The filter cake exhibits a uniform structure and excellent peelability, enabling continuous and efficient separation of nanoscale powders at a stable filtration rate. If traditional filters remain at... “ Solid-liquid separation ” the physical process—then, Xadias’ new device truly makes filtration a means of material purification and performance optimization. “ Starting point ”。

II. A Major Breakthrough in Solid-Liquid Separation Equipment —— New nanomicro-powder filtration machine

After years of research and development, Xiamen Xiadis has launched a new nanometer-scale powder filtration machine that represents the cutting edge of the industry and is regarded as a major technological breakthrough in the field of solid-liquid separation equipment. This equipment utilizes... “ High-precision, intelligent, and green manufacturing ” As the core concept, it boasts the following significant advantages:

1.  Direct separation of micron- and nanoscale particles with a retention rate as high as 99.9%

2.  Pure physical filtration method—no need to add any chemicals or additives.

3.  The separation, washing, and drying processes are integrated into one step, resulting in clear liquid, low moisture content in the filter cake, and an easily removable filter cake.

4.  Low energy consumption, high degree of automation, and low operating costs.

It can not only stably handle particle sizes as small as 25 nanometer-sized powder particles, whereas most filtration equipment on the market can only handle 300~500 Nano-sized powders. For the metal powder industry, this breakthrough has led to a significant improvement in electrical conductivity. —— Through precise separation and low-residue washing, the powder surface becomes purer and oxidation residues are reduced, enabling liquid clarity to be achieved. “ Zero suspension ” Washing and drying losses are virtually zero.

Wide range of applications, including:

• Industrial powder raw materials: Non-metallic mineral powders such as talc, heavy calcium carbonate, quartz, wollastonite, kaolin, mica, and graphite, as well as industrially synthesized powders including silicon carbide, corundum, silicon nitride, precipitated silica, titanium dioxide, and diamond.

This equipment can be widely used for the purification of industrial powdered raw materials, high-precision grading of micro- and nano-sized powders, and treatment of wastewater containing micro- and nano-sized pigments. It is an ideal piece of equipment for the modern new materials industry chain.

III. From Silver Powder to Silicon-Carbon: Multi-Scenario Implementation in the New Materials Chain

1.  Conductive Silver Powder and Electronic Paste Field

Silver powder is the foundation of high-end electronic pastes and chip packaging materials. Its particle size distribution and purity directly affect sintering density and electrical conductivity. Traditional filtration processes tend to leave behind agglomerated particles or result in the loss of fine powder, thereby increasing sintering resistance. 5~8% The nano-micron powder filtration machine can achieve... 25 High-efficiency separation at the nanoparticle level effectively reduces the loss of fine particles, thereby improving the yield and uniformity of the finished silver powder.

2.  Silicon-carbon anodes and new materials for lithium batteries

The preparation of silicon-carbon anode materials typically involves slurry dispersion systems with high viscosity and high specific surface area. Xadias equipment filtration technology avoids structural damage caused by conventional filtration methods while enabling high-purity solvent recovery and reducing solvent residue levels by approximately— 40% Significantly reduce side reactions and enhance the material’s cycle life and safety.

3.  Ultrafine alumina and silicon carbide powders

In ceramics, LED In the manufacturing of substrates and semiconductor wafers, the purity requirements for aluminum oxide and silicon carbide are as high as... 99. The concentration of effective particulate matter in the filtrate can reach PPM Above-grade. The new nano-micropowder filtration system ensures that the entire filtration process is free from secondary contamination and improves the uniformity of the filter cake. 30% The above applies to the final classification and cleaning of fine powders.

IV. Industrial Significance: Filtration Technology “ Invisible leverage ”

Although filtration appears to be an intermediate step in the manufacturing process, it plays an invisible role as a quality lever within the new materials industry chain.

In products such as silver powder, silicon carbide, and silicon nitride, particle size deviation... 0.1 μm All of these can lead to a decrease in conductivity or degradation of cycling performance. And Xadias’ new nanoscale powder filtration technology precisely addresses this issue. “ Micrometer-level error ” Establish an advantage.
