Brief introduction:
The BT-1800 dynamic image particle size and shape analysis system is a multi-function image particle analysis system which is composed of microscope, CCD camera, circulating and dispersing system and particle image analysis software. It could shoot image continuously when sample is flowing, then transfers these images one by one to the computer for analysis of particle size and shape, etc. Its basic working procedure is that put the sample into circulating tank, through the processes of ultrasonic dispersing, stirring, circulating, etc., to convey well dispersed sample into tailor-made flow cell which is under the objective of microscope. Meanwhile, shoot particle image and transfer real-time image to the computer for particle size and particle shape analysis. Finally, display and print analysis result. Its characteristics include automatically and continuously shoot images, easy operation, good sample representativeness and accurate and reliable result. It applies to abrasive, diamond, catalyst, paper pulp fiber, glass fiber, resin (including polishing resin, ion exchange resin and absorbent resin), etc.
Principle:
Based on the statistics of pixel number contained by each particle, calculate equivalent circle area, so that diameter of equivalent circle area, diameter of equivalent sphere volume, aspect ratio etc of particles are obtained, and then get the data of particle size distribution.
Specification:
Application fields:
Narrow distribution(Dmax:Dmin≤10:1) samples: Abrasive powder, spherical aluminum powder, tin lead alloyed powder, other alloyed powders.
powder materials after classification: aluminum powder, iron powder, magnesium powder, molybdenum powder, copper powder, zinc powder, rare alloyed powders and all kinds of gold powders, besides, including mica, graphite, wollastonite, kieselguhr, diamond, etc.
Other narrow distribution samples: catalyst, ceramic materials, electronic materials, chemical materials, military materials etc.
Fiber samples: paper pulp fiber, glass fiber etc.
Good repeatability
Reasons for good repeatability:
Laser, detector and signal transmission system are stable and reliable.
Stable and effective feeding system.
High-speed sampling system keeps the instrument always in optimum condition.
Sampling rate can reach 3500 times/second, and mass data can effectively reduce the influence of repeatability caused by little abnormal data
Kindly reminder:
Repeatability is primary index of particle size analyzer. It is worthless for particle size analyzer if repeatability is not good. Repeatability is related to the instrument, also, related to the operator, voltage, water quality and interference. It is a reflection of integrated factors.
Good accuracy
Reasons for good accuracy:
adopts high speed CCD, 120 pieces of images per second, and can analyze more than tens of thousands of particles per minute;
calibrate system accuracy through scale, analysis result is accurate and reliable;
complete sample preparation, it has the functions of stirring, dispersing, etc., and adopts fluid focusing technology, precision plunger pump technology, fast recognition technology of particle image, etc;
filter agglomerate or adhesive particles through the function of recognizing connected particles, in order to avoid that the test result is affected
