Common Dustproof Mesh Materials Brands and Characteristics Classification

Dustproof mesh is widely used in electronic products, but have you ever thought about the types and characteristics of dustproof mesh? Today, let's take a look together.

According to the principles of aerodynamics and the results of field environment wind tunnel tests, dustproof materials are processed into specific geometric shapes, opening ratios, and combinations of different pore sizes to create wind resistance walls, allowing circulating air (strong wind) to pass through the outer wall and form a disturbed airflow on the inner wall of the wall which achieves the effects of strong wind outside, weak wind inside, small wind outside and no wind inside, preventing dust from flying.

In daily use of consumer electronics such as mobile phones, computers, and cars, dust prevention, filtering, and silk screen printing are used to a large extent to adopt dustproof technology, greatly increasing the service life of electronic products.

Characteristics of common dustproof materials:

Non-woven fabric:

Non-woven fabric is made of bonded polyester and special materials. The traditional thickness is different from 0.10mm-0.75mm. Non-woven fabric can be combined with double-sided tape cutting and is widely used in laptop LCD screens, keyboards, microphones, LCD TV screens, digital cameras, camera screens, car sound insulation mats, and internal sound-absorbing liners, etc. According to customer requirements, non-woven fabric can also be flame retardant, waterproof, and back adhesive.

Sponge:

The biggest characteristic of dustproof sponges is their high density, relatively close internal structure, and good adsorption capacity. They can adsorb external dust and prevent it from entering. However, the dense structure also becomes an obstacle to the flow of air pipes, which significantly reduces the air flow there. It can be said that part of the heat dissipation performance is sacrificed to achieve better dustproof effects.

However, the cleaning of dustproof sponges is relatively complex. The sponge has strong water absorption and is easy to destroy the structure of the sponge by wringing it after washing with water, but it is not easy to remove the dust inside the sponge.

Dustproof sponge has strong dustproof effect but certain sacrifice in heat dissipation performance. It is mainly suitable for environments with more particles.

Nylon mesh:

The Nylon material is similar to the sponge, but its mesh size is larger, and the arrangement rule and structure design determine that the dustproof effect of the nylon dustproof mesh is not as good as sponge, but the impact on ventilation can be negligible.

Advantages: Good flexibility, not easy to break, anti-ultraviolet, aging resistance, flame retardant, easy to install and transport. Low raw material cost, cheap price, and double-layer network dust suppression rate can reach more than 95%.

Disadvantages: Complex production process, high production technology requirements.

Plastic:

Plastic is a material that sounds industrial, but its unique physical properties have strong advantages. When transporting or in use, organic glass is used as much as possible to avoid collision; transparent crystal is used to prevent dust from entering, but you can also see its interior device clearly. If you want to use this type of dust cover material, it is relatively simple, beautiful, and has no too complicated design, simple, soft, clear, and transparent.

Metal dustproof mesh:

Due to its large mesh size, the dustproof effect of metal dustproof mesh is the worst, but its ventilation performance is not as good as the other two. Metal dustproof mesh also has strong protection effect and can withstand strong external force, which is relatively safe.
