Problems solved by technology
[0004] The traditional particle size detection method is mainly based on the screening method. This method is mostly manual screening or mechanical vibration screening. Both of these methods have many disadvantages: secondary crushing of materials; long time consumption; large amount of human resources ; All materials cannot be tested; Online testing cannot be performed without affecting the continuity of the production process

The invention discloses a method for detecting particle size distribution based on a near infrared spectrum technology, and mainly relates to the technical field of application of analytical chemistryinstruments. The method comprises the following steps of sample collection and edition, data preprocessing, sample analysis, model correction, equipment installation, sample prediction and predictionresult output, wherein chemometrics is adopted, if compositions of samples are the same, spectrums of the samples are the same, and vice versa. If a corresponding relation (called an analysis model)between the spectrum and parameters to be measured is established, so long as the spectrum of the sample is measured, the required quality parameter data can be obtained quickly through the spectrum and the corresponding relation.
Description
Technical field [0001] The invention mainly relates to the technical field of analytical chemical instrument application, in particular to a method for detecting particle size distribution based on near infrared spectroscopy technology. Background technique [0002] Near infrared light (Near Infrared, NIR) is an electromagnetic wave between visible light (VIS) and mid-infrared light (MIR). The wavelength range of the near-infrared spectrum defined by ASTM is 780~2526nm, which is customarily divided into the near-infrared region There are two areas of near-infrared shortwave (780~1100nm) and near-infrared longwave (1100~2526nm). [0003] Near-infrared spectroscopy is mainly due to the non-resonance of molecular vibration when the molecular vibration transitions from the ground state to the higher energy level. The recording is mainly the frequency doubling and combination of the hydrogen-containing group X-H (X=C, N, O) vibration Frequency absorption. Different groups (such as met...
