Description

Technical Field

[0001] The utility model relates to the technical field of coating agent density detection, in particular to a seed coating agent density detector. Background Art

[0002] Seed coating agents are developed based on suspension concentrates, powders, and wettable powders. They require that the active ingredients can be gradually released without causing toxic effects on crop germination and growth. The seed coating film is water-permeable and breathable, and does not affect seed life and respiration. Seed coating agents are characterized by high efficiency, economy, safety, long-lasting effectiveness, and multifunctionality.

[0003] Density testing of seed coatings is a crucial step in quality control, helping to ensure their quality and performance. Density testing of seed coatings is typically performed using a gas displacement densitometer, such as the AccuPyc series. This method measures density using the gas displacement method. The basic principle of this method is to use a known chamber volume and measured pressure to calculate the sample volume according to the ideal gas law, thereby deriving the density. Because gas can enter all accessible open pore spaces, the measured volume represents the sample's skeletal volume, which is particularly important for porous materials like seed coatings.

[0004] However, during the testing of seed coating agents, since the seed coating agents will absorb a certain amount of moisture in the environment during storage, and there will also be certain impurities and debris attached to the surface of the seed coating agents, the moisture and impurities need to be removed before the test can be carried out. Only then can the density test be carried out. This additional processing process will affect the detection efficiency of the density tester. Utility Model Content
