It is also used in cosmetic powders test sieves. It is often used for particle size detection of imported raw materials or products that refer to international standards.

②Chinese Pharmacopoeia standard sieve: It is divided into sieves No. 1-9, and different sieve numbers correspond to different mesh numbers and sieve hole sizes.

What are the advantages of the cosmetic powders test sieve?

1. Ensure screening accuracy: Select high-precision sieve materials such as electroforming sieves, whose mesh size is uniform and consistent, with minimal error, and can accurately grade the particle size of cosmetic powders to ensure that the particle size of the powders after screening meets the product quality requirements.

2. Deal with the problem of cosmetic powders blocking the sieve: Cosmetic powders are usually very fine and easy to block the sieve. The high-frequency vibration generated by the cosmetic powders test sieve can effectively prevent the powders from blocking the sieve and improve the sieve

3. Deal with the problem of strong electrostatic properties of cosmetic powders: Cosmetic powders usually have strong electrostatic properties and are prone to agglomeration. Use sieves made of anti-static materials to reduce static electricity and reduce the possibility of powders agglomeration.

4. Solve the problem of high screening accuracy requirements: The particle size distribution of cosmetic powders has an important influence on product performance, and high-precision screening results are required. Use high-precision metal wire mesh to ensure the accuracy of the sieve aperture.

Recommended mesh size for cosmetic powders test sieves

50-100 mesh (about 150-300 microns): suitable for initial screening or removal of larger impurities, such as removing coarse particles that may be mixed in when screening talcum powders or mica powders raw materials. This mesh size is suitable for the initial processing of talcum powders or basic powders raw materials.

200-400 mesh (about 38-75 microns): suitable for fine screening of most cosmetic powders, such as regular production of loose powders, foundation or blush.

500-800 mesh (about 20-25 microns): suitable for high-end products or scenes requiring ultra-fine particles, such as light setting powders, highlight powders or sunscreen powders.

Why should the cosmetics industry use test sieves in the production of cosmetic powders?

1. Ensure consistent powders particle size

The particle size of cosmetic powders directly affects the texture, application effect, and skin comfort of the product. For example, particles that are too large may cause uneven makeup and affect the makeup effect; particles that are too small may cause the powders to clump or affect the feel of use when applied.

2. Remove impurities

During the production process of cosmetic powders, the powders may contain particles that do not meet the specifications, impurities, or other impurities (such as foreign matter, lumps, etc.). Test sieves can effectively screen out these impurities to ensure the purity and quality of the final product. Go

3. Improve production efficiency and consistency

If the powders screening process in cosmetic production is not accurate, it will lead to inconsistent powders particle sizes in different batches, affecting the final quality of the product. Test sieves can improve the accuracy of screening and ensure that each batch of cosmetic powders meets the predetermined specifications.

4. Control the fluidity and dispersibility of powders

The fluidity and dispersibility of powders are crucial in cosmetic applications. For example, if the particles of cosmetic powders such as flour, blush powders and eye shadow powders are too large or uneven, it may affect their dispersibility, making them uneven or piled up during application.
