FT-3500 Powder compression strength tester
one.Principles and TheoryPrinciple andtheory
：Particles undergo a series of changes during compression, including initial compression, particle rearrangement, initial structure formation, elastic deformation, plastic deformation, particle breakage, bond formation, further compaction, and elastic recovery after releasing pressure. The particle structure is destroyed and reorganized to form new bonds and compressed bodies; By applying the principal stress required for yield strength deformation to the powder, the relationship between the volume, porosity, compressibility, and yield strength of the powder (i.e., the relationship between principal stress and powder density) is analyzed using empirical equation method:Heckel、Kawakita、Adams.
The compression theory of equations and linear regression equations in northern Sichuan is used to analyze predictive analysis tools for new powder particle products, research and development of solid products, such as drug ratio and process selection, as well as the pressure requirements of compaction density3、 Function IntroductionFunction introduction
：7Using a hydraulic pressurization measurement system,Inch touch screen control, load unit control system can collect stress change data, set pressure and time data, displacement data can be directly read by displacement sensors, temperature and humidity data can be obtained through sensors, with multiple digitsADChips are used to ensure data analysis, with both automatic and manual operation modes coexisting; configurationPC.
The software can obtain the relationship between stress and powder density; The analysis and curve graph of the process data of linear transformation relationship of equations, establishing data models for production enterprises and research institutes
