Equipo de análisis de densidad sólida MDZ-II

Introducción

The equipment determine real volume of the sample by measuring the decrease of the gas capacity of the instrument sample chamber caused by putting in the sample. Gas can penetrate into tiny pores and surface irregular gap. So the measured sample volume can be used to calculate the sample’s density, measured values are more close to the sample’s true density.

Applies to coal,coke,petroleum coke,coal water slurry,estiércol líquido,metal,mineral rock,suelo,grain,medicamento,cerámico,cemento,materiales de construcción,refractario,heat barrier material,electrode material,chemical fertilizer,el plastico,fibre,catalyzer,revestimiento,chemical products and other materials true density testing.

Test system is consist of sample chamber and reference cell. In testing sample density, place certain volume sample into the sample chamber, then close the sample chamber, the instrument automatic monitor and collect sample chamber pressure; inject (or pull out) a certain amount of gas to sample chamber through reference cell, at the same time monitor the process pressure variations of the sample chamber and reference chamber, work out sample’s volume according to the measured series of pressure values and system parameters of the instrument, then work out sample’s density by the sample’s mass and volume.

Equipo de análisis de densidad sólida MDZ-II

Principales características:

1. High testing precision, good accuracy: better than the liquid pycnometer method;

2. Doesn’t break the sample: It does not change the physical and chemical properties of sample in the testing process (después de la prueba, sample is intact and can be used for other test);

3. Rapid test speed : completing the test process in 3-8 minutos;

4. Wide scope of application: It can measure various powder, granular, bulk solid and non-volatile liquid samples;

5. Widely test range : unlimited size of the sample density;

6. Alto grado de automatización: microprocessor-controlled automatic operation (auto-analysis, computation, mostrar), and has its own fault diagnosis function;

7. Operación simple: step-by-step tips;
