Description
Walnut shell abrasive is a natural abrasive material derived from
crushed walnut shells. It is a versatile and environmentally
friendly abrasive with a wide range of applications. Composition
and Characteristics: Walnut shell abrasive is made from the crushed
and ground shells of walnut fruits. It is a natural, biodegradable,
and renewable material. The shells are typically ground to various
sizes, ranging from fine powders to coarse grits. Walnut shell
abrasive is lightweight, angular, and has a hardness comparable to
soft wood. It also has low dust generation, making it a safer
alternative to some other abrasives.
It's important to note that walnut shell abrasive is not suitable
for all applications. It is not typically used in high-precision
grinding or applications where a very fine surface finish is
required. Additionally, individuals with nut allergies should avoid
contact with walnut shell abrasive products.
Overall, walnut shell abrasive offers a natural, environmentally
friendly, and versatile abrasive option for various industries and
applications.
Advantages of Walnut Shell
1. It has multi-faceted microporosity, strong interception power
and high removal rate of oil and suspended solids.
2.With multi-ribbon and different particle size, forming deep bed
filtration, enhanced oil removal capacity and filtration rate.
3.With hydrophobic oleophilic and suitable specific gravity, easy
to wash back, strong regenerative power.
4.The hardness is large, and it is not easy to corrode by special
treatment, no need to replace the filter material, only *0% per
year, reducing maintenance and repair time and improving
utilization. Walnut shell is a natural rolling material. It can not
damage the surface of the workpiece and has good polishing
effect.
Walnut Shell Application
Surface Cleaning and Preparation: Walnut shell abrasive is commonly
used for surface cleaning and preparation in various industries. It
is highly effective in removing dirt, grease, scale, paint,
coatings, and rust from different surfaces. It is gentle enough to
be used on delicate or sensitive materials, such as plastics, wood,
and fiberglass, without causing damage or surface deformation.
Deburring and Deflashing: Walnut shell abrasive is also utilized
for deburring and deflashing operations in metal, plastic, and
composite manufacturing processes. The angular shape and hardness
of the walnut shell particles help remove small burrs, sharp edges,
and flash from machined or molded parts without altering their
dimensions or surface finish.
Polishing and Finishing: Walnut shell abrasive is employed as a
natural polishing media for various applications. It is commonly
used in tumbling or vibrating machines for surface finishing of
metal, plastic, or ceramic components. Walnut shell particles act
as gentle abrasives, creating a smooth, polished surface without
scratching or damaging the workpiece.
Filtration Media: Due to its porous nature, walnut shell abrasive
is used as a filtration media in applications such as water
filtration, wastewater treatment, and air purification. The
irregular shape and porosity of walnut shells provide an effective
medium for trapping and removing particulates, oils, and impurities
from fluids and gases.
Cosmetics and Personal Care: Finely ground walnut shell abrasive is
utilized in cosmetic and personal care products as a physical
exfoliant. It is often found in facial scrubs, body scrubs, and
other exfoliating products. The gentle abrasiveness helps remove
dead skin cells and impurities, leaving the skin smoother and
brighter.
Pet Bedding and Litter: Crushed walnut shells are sometimes used as
bedding material for small animals and as a natural alternative to
traditional clay-based cat litter. The shells provide a soft and
comfortable substrate for pets, and their natural odor-absorbing
properties help control unpleasant smells.
