Determination of Foshan Washing Powder Particle Size

How is the particle size of laundry detergent determined? Next, let's learn about Foshan washing powder! (1) Determination principle The particle size of washing powder is not only an appearance index, but also has a certain influence on its use. If the particles are too large, it will affect the rapid dissolution of the washing powder, which is not conducive to the washing performance; if the particles are too small, a lot of dust will be generated during the packaging process, and it will be easy to agglomerate. The sample is sieved by a vibrator with a sieve with a specified hole sieve, and the weight of the sample left on the sieve and in the chassis is respectively weighed and expressed as a percentage to the total amount of the sample. (2) Instrumental test sieve: the diameter of the sieve frame is 200 mm, the screen surface of the wire mesh is woven, and a set of sieves with specified apertures are selected according to the requirements of the product standard to be tested, together with the chassis and the sieve cover. Electric shaker; balance. (3) The sample sample is not dried, and two samples are taken with a conical sample divider for use. (4) Process steps A set of clean and dry sieves with specified apertures selected as required, overlapped from bottom to top in order of aperture from small to large, and placed the sieve group on the chassis and installed together on the electric motor. on the oscillator. Accurately weigh 100 g of the sample divided by the conical sample divider, place it in the upper sieve, and add a sieve cover. Start the vibrator, stop vibrating after vibrating, remove the chassis and the sieve group, collect and weigh the samples on each sieve and in the chassis respectively. (5) Calculation of results Calculate the percentage of particle size according to the mass of the sample remaining on the sieve tray. A=B/m×In formula 100: A—Sieve retention rate on the sieve layer and the chassis, %; B--mass of the sample remaining on the sieve layer and the chassis, g; m—The mass of the sample, g. Note: The average value of multiple tests is used as the experimental result.
