Nanometer-Sized Silicon Carbide Powder Filter: A “Versatile Device” That Can Filter, Separate, and Automatically Wash.
Release time:
2025-11-17
In the increasingly sophisticated new materials industry chain, powder particles are no longer merely... “ The finer, the better. ” rather, it must simultaneously meet standards for indicators such as purity, particle size distribution, moisture content, and residual impurities. In particular, silicon carbide ( SiC This type of ultra-hard, ultra-stable, and extremely difficult-to-separate industrial powder is heavily utilized in high-end fields such as abrasives, electronic ceramics, semiconductors, and new energy technologies, placing higher demands on filtration and purification technologies.
In the past, the filtration of micron-sized powders often relied on conventional equipment such as filter presses and centrifuges. However, when particles enter the nanoscale range—such as ultrafine silicon carbide powder—traditional equipment generally suffers from several major drawbacks: low filtration efficiency, turbid filtrate, high moisture content in the filter cake, difficulty in washing the cake, and challenges in removing the cake from the filter medium.
Therefore, a product that can directly address “ Nano-micro powder material ” Solid-liquid separation equipment has become a genuine, pressing need in the industry.
01 Can the nanometer- and micrometer-sized silicon carbide powder filter automatically perform washing? The answer is: Yes, and it washes even more thoroughly.
What many manufacturers worry about most when filtering ultrafine powders is: —— It can't be washed clean.
Once the particle size of silicon carbide powder falls below... 1 μm the following behavioral characteristics will emerge:
- Easy to reunite
- Easily clogs traditional filter cloths.
- The cleaning solution cannot penetrate evenly.
- Extremely low cleaning efficiency
- Impurity residues are difficult to control.
And the new nanomicro-powder filter machine is not designed that way in the first place. “ Minor redesign of traditional equipment ” Rather, it is a full-process engineering system designed for nanoscale particles.
It can do this:
✔ Automatic washing
Implement automated cleaning of the filter cake inside the equipment to minimize residual impurities.
✔ Washes more evenly
The cleaning solution is not. “ Hit twice. ” Rather, it achieves deep cleaning between micro- and nano-sized particles.
✔ Low detergent consumption
Physically clean separation, no chemical additives required, significantly reducing washing costs.
Therefore, the challenging issue of washing ultrafine powders such as silicon carbide, silver powder, and aluminum oxide has been effectively addressed by this type of equipment.
One-sentence summary:
Not only does it offer automatic washing, but its washing performance also significantly surpasses that of conventional filter presses and centrifugal equipment.
02 Not only can it wash, but it can also: filter. + Separation + Drying and integration completed.
Users often ask: “ Can it serve multiple purposes with a single machine? After filtration, does it also need to perform dehydration? And can it be used as a pre-treatment step before drying? ”
The core value of this new nanomicro-powder filtration machine lies in the fact that... Three-in-one:
1 ) Filter —— The interception rate is as high as 99. The concentration of effective particulate matter in the filtrate can reach PPM levels.
Thanks to patented micro- and nano-control technology,
- Can directly intercept nanoparticles.
- The filtrate is clear and transparent.
- No chemicals required
- Will not occur the common issues found in filter presses. “ Running powder, turbid liquid ”
This is an extremely critical step in the production of nanopowders.
2 ) Washing —— Automation System Integration
The powder is precisely washed inside the equipment, significantly reducing residual impurities.
3 ) Dry —— The filter cake has a lower moisture content.
Achieve:
- Less residual liquid
- The filter cake is loose and easy to peel off.
- The backend has lower energy consumption for drying.
This is particularly important for high-value materials such as silicon carbide, silicon nitride, zirconium powder, and nickel powder.
This means:
Filtering — Washing — Drying no longer requires three sets of equipment—just one is needed.
03 ｜Why is it “ Nano-micron powder filter machine ” What exactly has it broken through?
Traditional filter presses address... “ Tens of micrometers in size ” the solid-liquid separation issue,
However, filtering nanoscale powders presents an entirely different engineering challenge.
The breakthroughs of the new nano- and micro-powder filtration machine include:
1 ) The ability to directly separate micron- and nanoscale particles
No reliance on chemicals, no need for coagulation, and no addition of any filter aids.
Pure physical filtration can achieve this. 99. The concentration of effective particulate matter in the filtrate can reach PPM levels. Retention rate.
2 ) Controllable filter cake structure
Uniform, controllable, and stable structure.
3 Low energy consumption, fully automatic, continuous operation
More suitable for modern powder plants “ Unmanned, stable, and energy-efficient ” the direction of.
4 ) Wider range of compatible materials
Coverage:
- Non-metallic mineral powders: talc powder, heavy calcium carbonate, kaolin, wollastonite, mica, graphite, quartz, and others.
- Industrial Powders: Silicon Carbide, Corundum, Silicon Nitride, White Carbon Black, Titanium Dioxide, Diamond
- Nanometer- and Micrometer-Sized Metal Powders: Silver Powder, Nickel Powder, Zinc Powder, Aluminum Powder
- Various oxides: iron oxide, zinc oxide, aluminum oxide, silicon oxide, magnesium oxide, and others.
In today’s new materials, new energy, and electronic powder industries, this is of great significance.
04 ｜Silicon Carbide Powder: Why is the use of this type of equipment strongly recommended?
Silicon carbide itself possesses:
- High hardness
- High specific surface area
- Difficult to settle
- Severe reunion
- The finer the particle size, the harder it is to filter.
In fields such as electronic ceramics, silicon carbide single crystals and polycrystals, grinding materials, and carbon-enhancing agents for new energy applications, the purity of powders and production consistency directly determine product performance.
The advantages of using nanomicro-powder filtration systems are very obvious:
✔ No loose powder, no cloudy liquid.
The most challenging issue to solve with traditional equipment “ The nano-level polishing liquid simply won't come out at all. ” The issue has been thoroughly resolved here.
✔ Washes cleaner
Avoids residual impurities and is particularly suitable for the preparation of high-end silicon carbide powders.
✔ Lower moisture content
Reduce energy consumption in the downstream drying process and improve overall production efficiency.
✔ High degree of automation
Greatly reduce the risk of manual operations.
✔ Easier to scale up for industrialization
Suitable for continuous production, closed-loop factories, and intelligent production bases.
05 ｜Summary:
One for “ The Era of Nanoscale Micropowder Particles ” Industrially designed filtration equipment
If summarized in one sentence:
The new nano- and micro-powder filtration machine is one that can truly achieve...
“ Filtering + Washing + Dry ”
