Silicon carbide ceramic punching block

Silicon carbide ceramic punching block is a functional ceramic component made of high-purity silicon carbide (SiC) powder and sintered by advanced technology, with precise and regular through-hole structure. It is not made through the traditional “punching” process, but through mold forming. The size, shape, and distribution of the holes are pre-set before sintering, ensuring the consistency and accuracy of the product.

Silicon carbide materials themselves possess unparalleled material properties, making silicon carbide perforated blocks an ideal choice to replace traditional metal, graphite, and other oxide ceramic porous components
Excellent high temperature resistance: It can work stably for a long time in high temperature environments above 1600 ° C without softening, melting or deformation.
Extremely high mechanical strength: Its compressive strength and bending strength are much higher than most porous ceramics and metal materials, and it can withstand extremely high mechanical loads and pressure impacts.
Excellent thermal shock stability: insensitive to rapid temperature changes, able to withstand rapid heating and cooling without cracking, solving the problem of fragility of ordinary ceramics.
Outstanding wear and corrosion resistance: It has extremely high resistance to acid and alkali corrosion, molten metal and salt erosion, as well as extremely low friction coefficient and long service life.
Accurate and controllable porosity: The pore size, porosity, and permeability can be precisely designed and controlled according to application requirements, achieving precise fluid distribution, filtration, or flow restriction functions.

The core problems that the product can solve
The emergence of silicon carbide ceramic punching blocks effectively solves a series of pain points of traditional porous materials under extreme working conditions:

1. Solve the problem of metal materials not being resistant to high temperatures and corrosion: Replace porous metals such as stainless steel and high-temperature alloys, overcome their defects of easy oxidation, creep at high temperatures, and corrosion perforation in corrosive media.
2. Solve the problem of insufficient strength and easy oxidation of graphite materials: Compared with porous graphite, it has higher mechanical strength and hardness, and will not burn or consume in an oxidizing atmosphere, making it more suitable for a wider range of environments.
3. Solve the problem of poor thermal shock resistance of ceramics such as alumina: Compared with alumina and zirconia ceramics, their thermal conductivity is higher and their coefficient of thermal expansion is lower, thus improving their thermal shock resistance by several orders of magnitude and eliminating brittle cracking caused by sudden temperature changes.
4. Solve the problem of traditional filters being prone to clogging and having a short lifespan: Its smooth pore wall and inert surface can effectively prevent material adhesion, making it easy to backwash and clean, greatly extending maintenance cycles and service life.

Main application areas
With its unique performance combination, silicon carbide ceramic punching blocks play an irreplaceable role in the following industrial fields:
High temperature gas distribution and filtration
Molten metal filtration: used for purification of aluminum, copper, zinc and other molten materials before casting, effectively removing non-metallic inclusions.
Chemical fluidized bed: As a gas distribution plate, it ensures that the reaction gas passes uniformly through the catalyst bed, improving reaction efficiency.
Kilns and Heat Treatment: Used as burner nozzles and radiation tube liners for high-temperature furnaces to achieve uniform heat distribution.
Catalysis and Reaction Engineering
Catalyst carrier: Its large specific surface area and through pores make it an ideal substrate for three-phase (gas, liquid, solid) reaction catalysts.
Structured reactor: As the core component of chemical reactors, it achieves efficient mixing and mass transfer of reactants.
Environmental Protection and Energy
High temperature flue gas dust removal: used for particulate matter filtration of high-temperature hot gases in fields such as garbage incineration and coal chemical industry.
MEMS burner: As a porous medium for microscale burners, it achieves stable and efficient combustion.
Other precision industries
Acoustic components: used as muffler components in high-temperature and corrosion-resistant environments.
Sensor protective cover: provides porous mechanical protection for sensors such as thermocouples, without affecting measurement response.
