Nylon sieve

Nylon sieve is a common screening tool, widely used in laboratories and industrial production, mainly used for screening, grading and filtering of granular materials. The sieve is made of nylon material, which is lightweight, corrosion-resistant and wear-resistant, and is suitable for screening a variety of materials. The following is a detailed introduction to nylon sieve, including its characteristics, application scenarios and precautions for use.

How does the nylon sieve work?

Nylon sieve has sieve holes of specific size and shape. When materials containing particles of different sizes pass through the screen, particles with a size smaller than the sieve holes can pass through the sieve holes, while particles with a size larger than the sieve holes are retained on the screen, thereby achieving the separation of particles of different sizes.

Features of nylon sieve

1、Lightweight and durable: Nylon sieve is light, easy to carry and operate, and has high wear resistance and long service life.

2、Corrosion resistance: Nylon material has good tolerance to chemical substances such as acids and alkalis, and is suitable for screening corrosive materials.

3、Good flexibility: Nylon sieve has a certain elasticity, which can effectively prevent material blockage and is suitable for screening materials with high viscosity.

4、Uniform aperture: The aperture distribution of nylon sieve is uniform, the screening accuracy is high, and it is suitable for fine screening.

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 are the advantages of nylon sieves?

1. 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.

2. High precision: Nylon sieve 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.

3、Good flexibility: Nylon sieve 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.

4、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?

1、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, nylon sieves can be used to screen out impurities such as bran, making the flour more delicate.

2、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.

3、Chemical industry: Widely used in the screening and filtration of various chemical raw materials, intermediates, and finished products, such as particle size classification of plastic particles, rubber powder, pigments, dyes, etc., and filtration and impurity removal of chemical liquids. For example, in paint production, nylon sieves can be used to filter impurities in paint and improve the quality of paint.

4、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.

5、Aquaculture industry: used for water quality filtration and feed screening in aquaculture ponds. In aquaculture, nylon sieves can be installed at the water inlet or filtration equipment of the pond to filter out impurities and plankton in the water, providing a clean water environment for aquaculture organisms; they can also be used to screen feed to ensure the uniformity of feed particles, which is conducive to the feeding of aquaculture animals.

Recommended nylon mesh number

20 mesh - 60 mesh: Nylon sieve is suitable for screening coarse particle materials, such as materials with larger particles or preliminary screening.

70 mesh - 120 mesh: Nylon sieve is suitable for screening general particle materials, such as screening and filtering of general particle materials.

150 mesh - 300 mesh: Nylon sieve is suitable for screening fine particle materials, such as screening and filtering with higher precision.

Above 300 mesh: Nylon sieve is suitable for screening ultra-fine particle materials, such as screening and filtering with very high precision.

How to clean Nylon sieve?

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

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

3. Control the cleaning frequency: Do not clean nylon 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.

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

5. Do a good job of maintenance: Store the cleaned nylon sieve in a dry and ventilated environment to avoid moisture, high temperature and direct sunlight. If it is not used for a long time, it can be packaged with a dust cover or plastic bag to prevent dust and debris from contaminating the screen again.

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 nylon sieve.
