Detergent Powders Test Sieve

What is a detergent powders test sieve?

Detergent Powders Test Sieve is a device used for screening, analysis and quality control of detergent powders. It is usually used in laboratories, production lines or quality inspection departments to ensure the uniformity of particle size and quality stability of detergent powders. As a fine powders material, the screening test of detergent powders can help manufacturers adjust the formula, improve product quality and meet relevant standard requirements.

How does the detergent powders test sieve work?

1. Screening: Place a certain amount of detergent powders sample evenly on the sieve surface of the test sieve, start the equipment, and use the centrifugal force and gravity generated by vibration to make the detergent powders sample pass through the sieve and layer according to the particle size distribution.

2. Screening process: After the sieve is screened layer by layer, detergent powders with different particle size ranges is obtained. Larger particles will be retained in the upper sieve, while smaller particles will pass through the sieve into the lower layer.

3. Result analysis: By weighing the sample weight in different sieve layers, analyzing the distribution of each particle size segment, calculating the particle size distribution curve of the detergent powders, and evaluating the product quality.

What can the detergent powders test sieve be used for?

1. Particle sorting: Detergent powders test sieve can be used to sort the particles in the detergent powders according to size, helping manufacturers understand the particle distribution of the product.

2. Quality control: By performing a test sieve analysis on the detergent powders, it is possible to evaluate whether the particle size of the product meets the standard requirements, thereby performing quality control and improving the production process.

3. Product improvement: According to the results of detergent powders test sieve, manufacturers can adjust the production process and optimize the product formula to improve the quality and market competitiveness of the detergent powders.

Structure of the detergent powders test sieve

Detergent powders test sieve test sieve is usually composed of a sieve frame, a sieve, a vibrating device, and a bracket. Detergent powders is sorted on the sieve through vibration. Larger particles will be retained by the sieve, while smaller particles will fall through the sieve into the container below.

What are the advantages of detergent powders test sieve?

1. Uniformity of detergent powders particle size: Through the screening of the detergent powders test sieve, detergent powders with uniform particle size distribution can be obtained. This uniformity not only improves the use effect, but also makes the detergent powders more stable during packaging and transportation, reducing breakage and waste.

2. Break up lumps: Detergent powders test sieve usually has a vibration function. During the material conveying process, the high-frequency vibration of the sieve body driven by the vibration motor can cause relative movement between the detergent powders particles, thereby breaking up the lumped detergent powders.

3. Intercept impurities: The screen of the detergent powders test sieve can intercept various impurities mixed in the detergent powders, such as foreign matter in the raw materials, metal chips generated by wear of production equipment, etc.

4. Reduce the adhesion of detergent powders particles: Detergent powders test sieve can help detect whether there is a problem of adhesion of particles. If it is found that the particles are seriously adhered, the shape and texture of the particles can be improved by adjusting the formula or production process to reduce the adhesion of particles.

Application of detergent powders test sieve

Detergent powders test sieve is widely used in production, research and development, quality control, batch inspection, market analysis and other links. It can help manufacturers ensure the particle size consistency of detergent powders, improve product quality, optimize formula, and ensure compliance with standards and regulations. Through particle size analysis, detergent powders test sieve is not only an important tool for quality inspection, but also a key equipment for product improvement and production optimization.

How to test detergent powders test sieve?

①Sample preparation: The sample is not dried, and two samples are taken with a conical sample divider for standby use.

②Sieve group assembly: select a set of clean and dry sieves with specified apertures according to the requirements, overlap them from bottom to top in the order of aperture from small to large, place the sieve group on the chassis, and install them together on the electric oscillator.

③Weigh the sample: weigh 100g of the sample separated by the sample divider, place it in the upper sieve, and cover the sieve.

④Start oscillation: start the oscillator, if a parallel reciprocating oscillator is used, the sieve vibrates for (4±0.5)min; if a vertical oscillator is used, the sieve vibrates for (8±0.5)min. After stopping the oscillation, remove the chassis and sieve group, collect and weigh the sample mass on each sieve and in the chassis respectively.

⑤Repeat the test: take another sample separated by the sample divider and repeat the above test. The average value of two tests is taken as the test result, and the sum of the masses of the residual samples on each layer of sieve and the samples in the bottom plate should not decrease by more than 1% compared with the mass of the input samples, otherwise the test must be repeated. At the same time, the deviation of the two test results should not exceed 1.5g.
