Application field impact - wire diameter
► Features: Coarse wire diameter (such as 1-3mm), large mesh size, strong impact resistance and wear resistance, but low filtration accuracy.Typical application areas:
1. Mining and Quarry
-Vibration sieve: used for coarse screening of ores (such as iron ore and coal), to withstand the impact of high hardness materials and avoid mesh breakage.
-Ore washing equipment: separates large ore blocks from sediment, with a coarse wire diameter that can resist water flow erosion and particle friction.
2. Architecture and Environmental Protection
-Concrete aggregate screening: Separate stones (particle size 5-40mm) from sand, and the coarse wire mesh surface is not easily deformed.
-Garbage sorting: intercepting large garbage (such as plastic bottles, metal waste), suitable for high load solid waste processing lines.
3. Heavy machinery protection
-Construction machinery protective cover: such as the feeding port protective net of excavators and crushers, to prevent large pieces of material from splashing.
-Industrial equipment dust screen: used for the air inlet of fans, air compressors and other equipment to block large particles of debris (such as leaves and gravel)
► Medium wire diameter (0.2-0.8mm) - balanced strength and accuracy
Features: Moderate wire diameter, possessing both strength and filtering ability, with the widest range of application scenarios.Typical application areas:
Features: Moderate wire diameter, possessing both strength and filtering ability, with the widest range of application scenarios.Typical application areas:
1. Food and Chemical Industry
-Particle screening: such as grain (wheat, corn) grading, chemical raw material (fertilizer particles) screening, silk diameter can match 0.5-5mm aperture, balancing screening efficiency and mesh durability.
-Liquid filtration: such as preliminary filtration of soy sauce and alcohol, intercepting visible impurities (such as sediment) with a thread diameter strength sufficient to withstand liquid pressure.
2. Medicine and Agriculture
-Screening of traditional Chinese medicine decoction pieces: Separate medicinal granules of different specifications (such as Huangqi tablets and goji berries), with silk diameter and wear resistance suitable for long-term high-frequency use.
-Aquaculture: fish pond interception, seedling pond filtration (such as separating fish fry and debris), with good flexibility in wire diameter and not easily rusted.
3. Mechanical manufacturing
-Hydraulic system filtration: intercepts metal debris (particle size 50-100 μ m) in the oil, with a wire diameter strength that can withstand hydraulic oil pressure.
-Automotive parts cleaning: used to clean the material carrying mesh of equipment, resistant to mechanical vibration and cleaning agent corrosion.
► Fine wire diameter (wire diameter ≤ 0.2mm) - High precision, low load scenarios
Characteristics: Fine wire diameter (such as 0.05-0.2mm), dense mesh, high filtration accuracy but low strength, and need to avoid large particle impact.Typical application areas:
Characteristics: Fine wire diameter (such as 0.05-0.2mm), dense mesh, high filtration accuracy but low strength, and need to avoid large particle impact.Typical application areas:
1. Precision filtration and scientific research
-Laboratory analysis: such as chemical reagent purification, cell screening (pore size matching cell size), fine wire diameter can achieve micron level filtration (such as 0.1mm pore size corresponding to 100 μ m accuracy).
-Preparation of nanomaterials: Separate nanoparticles (such as graphene and quantum dots), and ensure uniformity of pore size through electro etching process for wire diameter.
2. Refined production of food and medicine
-Syrup precision filtration: removes caramel colored particles and microorganisms (such as yeast), with corrosion-resistant silk diameter (made of 316L stainless steel) and does not contaminate food.
-Injection filtration: The pharmaceutical grade sieve should comply with GMP standards, with a wire diameter error of ≤± 2%, to ensure the interception of bacteria (such as a 0.22 μ m filter membrane corresponding to a wire diameter of about 0.1mm).
3. Electronics and Semiconductors
-Photoresist filtration: intercepts impurity particles (particle size<5 μ m) in the photoresist solution, and the wire diameter needs to be anti-static (such as nickel plating on 304 stainless steel) to avoid particle adsorption affecting chip yield.
-High purity metal powder screening: such as grading of lithium battery cathode materials (lithium cobalt oxide), the fine wire mesh surface can ensure uniform powder particle size distribution.
► The synergistic effect of wire diameter and material
-Corrosion resistant scenario: In fields such as chemical and marine engineering, 316L stainless steel fine wire mesh is required. Although it has low strength, it is resistant to acid and alkali corrosion and suitable for filtering corrosive liquids (such as electrolytes).
-High temperature environment: In metallurgical, boiler and other scenarios, the thick wire diameter 310S stainless steel screen can withstand high temperatures above 800 ℃ to avoid wire diameter softening and fracture.
-Explosion proof requirements: Fine wire anti-static screens (such as copper plating on the surface) are required in scenarios such as flour mills and oil workshops to prevent sparks from friction.
The core logic of wire diameter selection
| Wire diameter range |
Core advantages |
Typical scenario | Key indicators |
|---|---|---|---|
| Coarse wire diameter | High strength and impact resistance | Mining, construction, heavy machinery | Tensile strength, wear resistance coefficient |
| Medium wire diameter | Balance strength and accuracy | Food, Chemical, Agriculture | Screening efficiency and corrosion resistance |
| Fine wire diameter | High precision, low load | Medicine, electronics, scientific researchMedicine, electronics, scientific research | Aperture tolerance, surface roughness |
► Attention
- The wire diameter should match the aperture - under the same wire diameter, the smaller the aperture, the lower the strength of the mesh surface (such as a mesh with a wire diameter of 0.5mm and an aperture of 0.5mm, which is more prone to deformation than a mesh with an aperture of 2mm). Mechanical calculations (such as mesh tension and load weight) should be carried out during design to ensure the service life.
