Nylon sieve

Nylon sieve sieve surface uses a highly elastic nylon mesh with uniform and fine openings. It filters flour or powdered sugar evenly and finely, effectively preventing clumping. The standard sieve diameter is typically 20 cm or 24 cm, making it lightweight and portable. A variety of mesh sizes are available, from 60 mesh for general flour to finer options like 80 and 100 mesh, catering to needs ranging from coarse sieving to extremely fine material filtration.

How does the nylon sieve work?

Nylon Sieve has sieve openings of a specific size and shape. When the mixture to be processed is placed on the sieve surface and an external force (such as vibration or horizontal movement) is applied, the material layer begins to loosen and redistribute. As material containing particles of different sizes passes through the sieve, particles smaller than the sieve openings can pass through, while particles larger than the sieve openings are trapped on the sieve, thus achieving separation of particles of different sizes.

Features of nylon sieve

Nylon Sieve combines lightweight durability, chemical resistance, good flexibility, and uniform pore size, easily handling corrosive environments and high-viscosity materials, effectively preventing clogging.

Lightweight and Durable: Made from high-strength nylon filaments, the material's density is significantly lower than metal, resulting in a very light overall weight. This reduces labor intensity during frequent movement and prolonged handheld operation.

Corrosion Resistance: Nylon material possesses stable chemical properties, exhibiting excellent resistance to common acids and alkalis. This characteristic eliminates concerns about rust or chemical corrosion like metal screens, ensuring the purity of the screening process and the safety of the equipment.

Good Flexibility: Compared to rigid screens, nylon screens possess a degree of elasticity and flexibility. During screening, slight deformation of the screen surface effectively shakes off particles stuck in the mesh, reducing clogging for materials that are prone to sticking, clumping, or have high viscosity.

Uniform Aperture: Through a precise weaving process, the nylon screen has a regular mesh structure with accurate control over the aperture size and uniform distribution. This consistency allows the screened materials to be separated according to particle size standards, with a clear boundary between oversize and undersize materials, thus achieving the requirements of grading and filtration.

The structure of nylon sieve

Nylon sieve consists of a sieve frame, sieve mesh, sealing ring, fixing device, etc. The sieve frame is usually made of metal (such as stainless steel, aluminum alloy) or plastic, and is used to fix the sieve mesh and provide support. Common sieve frame shapes are round or square. The sieve mesh is made of nylon material, which is light, corrosion-resistant, and flexible.

What is the difference between a nylon sieve for industry and a nylon sieve?

The difference between industrial nylon sieves and ordinary nylon sieves lies in their performance requirements. Industrial sieves typically use high-strength, highly abrasion-resistant nylon materials with thicker wire diameters and more precise mesh counts, capable of withstanding continuous mechanical impacts and harsh working conditions. Ordinary nylon sieves, on the other hand, are mostly used in light-load applications such as home and agriculture, where durability and precision requirements are relatively lower.

 

Different uses

Nylon test sieves are mainly used for particle analysis and screening tests in laboratory environments, and are usually used for scientific research, quality inspection or standard analysis, such as particle size distribution tests in pharmaceutical, food, chemical, metallurgical and other industries. Nylon sieves are usually used for industrial or daily screening, suitable for filtering or classification of large particle materials, such as flour screening, soil filtration, etc.

Different precision requirements

The mesh number of the test sieve is accurate and meets national or international standards (such as ISO, ASTM, GB, etc.), and the aperture error is strictly controlled to ensure the accuracy and repeatability of experimental data. Nylon sieves are used for coarse screening, with large aperture errors and low screening accuracy requirements.

Different manufacturing standards

Nylon test sieves use high-precision screens and stainless steel or aluminum alloy frames to ensure wear resistance, chemical corrosion resistance and structural stability. Most nylon sieves are made of ordinary nylon materials, and the frame may be plastic or ordinary metal.

What are the advantages of nylon sieves?

Nylon Sieve boasts advantages such as smooth filaments with uniform pore size; flexible and wear-resistant material that is not easily deformed or damaged; good chemical stability and resistance to acid and alkali corrosion; and strong water permeability and large screening flow rate.

Good water permeability: When filtering water or other liquid materials, nylon sieve has good water permeability, which can quickly let the liquid pass through the sieve, effectively intercept solid particles, and improve the filtering efficiency. It is often used in water treatment, liquid filtration and other fields.

High precision: It can be made into screens with different mesh numbers and apertures through precise weaving technology. The mesh number range is usually between dozens of meshes and hundreds of meshes, which can meet various fine screening needs and achieve high-precision grading and screening of materials.

Good flexibility: It has high flexibility and can withstand a certain degree of deformation without breaking during the screening process. It is suitable for screening some materials with certain viscosity or irregular shapes, and can effectively avoid the problem of material blockage or reduced screening efficiency due to the sieve being too hard.

Strong corrosion resistance: It has good tolerance to chemical substances such as acids and alkalis, can maintain stable performance in different chemical environments, is not easily corroded, and can be used to sieve various corrosive materials, such as chemical raw materials, electroplating liquids, etc., to extend the service life of the sieve.

What is nylon sieve used for?

Nylon Sieve removes impurities and ensures uniform particle size by sieving powdered and granular materials; it can also be used as a filter medium to trap impurities in water, thereby purifying the water. The following are specific applications of this product in different industries.

Food industry: Nylon sieves are used for screening powdered or granular foods such as flour, starch, powdered sugar, and condiments to remove impurities and unqualified particles to ensure the quality and taste of food. For example, in the flour production process, these sieves can be used to screen out impurities such as bran, making the flour more delicate.

Pharmaceutical industry: Screening of drug particles, powders, etc. to ensure that the particle size of the drugs is uniform and meets the production process and quality standards. For example, in capsule production, drug particles are screened by nylon sieves to ensure that the size of particles loaded into the capsule is consistent, thereby ensuring the accuracy of drug dosage.

Water treatment industry: In the process of sewage treatment and drinking water purification, as a filter medium, it is used to intercept suspended matter, granular impurities, etc. in water to purify water quality. For example, in the filtration process of the water plant, nylon sieves can remove fine particles in the water to make the water quality meet the drinking standard.

How to clean Nylon sieve?

Check the condition of the sieve: Before cleaning it, carefully check whether the sieve is damaged, cracked or deformed.

Understand the characteristics of impurities: clarify the type, nature and adhesion of impurities on it in order to choose the appropriate cleaning method and tools.

Control the cleaning frequency: Do not clean sieve too frequently to avoid unnecessary damage to the sieve. The cleaning cycle should be reasonably determined according to the frequency of use and blockage of nylon sieve. Too frequent cleaning may cause fatigue of the sieve fiber and reduce the strength of sieve.

 Maintain uniform cleaning: During the cleaning process, ensure that the entire surface of the sieve is cleaned evenly to avoid excessive local cleaning and incomplete cleaning of other parts.

Nylon sieve is an economical and practical screening tool, widely used in laboratories and industrial production. Through reasonable selection and use, the performance advantages of nylon sieve can be fully utilized to meet the screening needs of different materials. At the same time, paying attention to daily maintenance and care can extend the service life of sieve.
