ความละเอียดเป็นตัวบ่งชี้สำคัญในการวัดขนาดและการกระจายตัวของอนุภาคในสารเคลือบ, มักจะแสดงเป็นไมครอน. This paper introduces a method for measuring the fineness of paint, which is measured by a scraper fineness meter. The accurate measurement of fineness is of great significance to the quality control and product performance of coatings. In the process of production and application of coatings, the size and dispersion of particles have an important impact on the performance and appearance of coatings. Fineness is a key parameter to measure the particle size and dispersion in coatings, which can affect the uniformity, adhesion and appearance quality of coatings. ดังนั้น, the accurate determination of the fineness of the coating is very important to ensure the quality and performance of the coating.

Determination method and procedure
งานเตรียมการ

การจัดเตรียมตัวอย่าง: Select the paint sample to be tested and ensure that the sample is representative.

Prepare equipment: Prepare the necessary instruments and materials such as scraper fineness meter, minor paint knife or glass blender.

Measurement process

1, choose the right scraper fineness meter, choose the right scraper fineness meter range according to the fineness range of the paint sample.

2, before using the scraper fineness meter, the instrument must be thoroughly cleaned to ensure that it is clean and pollution-free.

3, use a minor paint knife to fully stir the paint sample, so that its particles are evenly distributed.

4, drop a small amount of sample into the groove of the scraper fineness meter, so that it is full of grooves and slightly redundant.

5, pull the scraper over the sample, and then observe the particles in the groove at a specific Angle to the light for a short time.

6. Record the position of uniform exposure of particles on the fineness meter, and indicate the fineness of the coating in microns.

Quality control fineness is one of the important indexes to measure the quality of paint. The accurate determination of the fineness of the paint helps to control the size and dispersion of the particles in the paint, thus ensuring the uniformity and quality stability of the paint.

The fineness of the coating can affect the performance and application effect of the coating. The size and dispersion of the particles can affect the adhesion, gloss and fluidity of the paint, thus affecting the appearance and durability of the paint.

Formulation optimization By measuring the fineness of the coating, it can provide important information for the optimization of the coating formulation. Understanding the distribution of particles in the paint helps to adjust the formulation for better performance and results.

Fineness measurement is an important step in coating quality control and product performance evaluation. Accurately measuring the size and dispersion of the particles in the coating helps to ensure the quality stability, performance consistency and appearance of the coating. Fineness measurement results are important for coating manufacturing, quality control and product application, helping to ensure that the final product meets the expected requirements.
