Оборудование для анализа плотности твердого тела MDZ-II

Введение

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,жижа,металл,mineral rock,земля,зерно,лекарство,керамический,цемент,строительные материалы,refractory,heat barrier material,electrode material,chemical fertilizer,пластик,fibre,catalyzer,покрытие,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.

Основные особенности:

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 (После теста, sample is intact and can be used for other test);

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

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

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

6. Высокая степень автоматизации: microprocessor-controlled automatic operation (auto-analysis, computation, отображать), and has its own fault diagnosis function;

7. Простое управление: step-by-step tips;
