Thermoelectric graphite paste for cast iron‘s good thermal and electrical conductivity should not be underestimated

graphite paste for cast iron

In our modern industrial production process, a variety of materials can be used as an electric atomizer, but compared with the effect, it should be said that the effect of thermoelectric graphite paste for cast iron is better. Therefore, modern graphite paste for cast iron is widely used in atomic absorption.

Use the thermoelectric graphite paste for cast iron to quantitatively inject the sample into the graphite paste for cast iron through the sample feeder, and use the graphite mold factory as the resistance heating body. After charging, the temperature rises rapidly, so the sample can be atomized. It consists of heating power supply, protective gas control system and graphite paste for cast iron furnace. External power is applied to both ends of the graphite paste for cast iron to supply energy to the atomizer. The temperature generated by the current flowing through the graphite paste for cast iron is as high as 3000°C, so the element to be measured in the graphite paste for cast iron becomes a ground state atomic vapor. The shielding gas control system controls the shielding gas. When the instrument is started, the protective gas Ar circulates. After the air combustion is completed, the AR airflow will be cut off. The Ar gas in the external gas path of the graphite die device flows along the outer wall of the graphite paste for cast iron to protect the graphite paste for cast iron from ablation. The Ar gas in the internal gas channel flows from both ends of the tube to the center of the tube, and flows out from the center hole of the tube to effectively remove the matrix vapor generated during the drying and ashing process, while protecting the protonated atoms from oxidation. Its good thermal conductivity and thermal conductivity cannot be underestimated.

Thermoelectric graphite paste for cast iron has less metal impurities and good workability. In addition, the pyrolytic coating graphite paste for cast iron can also reduce the penetration and memory response of the sample to a certain extent. When using a furnace, the main thing is to hope that the furnace has a good service life, but the graphite furnace will still be affected by the characteristics of the sample matrix and the temperature during use. Of course, graphite furnaces of different brands have different uses. Therefore, when we buy, we can buy the famous graphite furnace, which can guarantee the quality.
