Recently, a series of comparative experiments in the electrochemical laboratory have confirmed that the EpoPowder F (glass filled epoxy resin powder) hot pressed inlay resin powder provided by Chain Metallography is a suitable inlay material for high temperature, high pressure, and corrosive environments after inlay. This solves the selection of inlay materials under high temperature, high pressure, and corrosive conditions.


The test materials, environment, and purpose are as follows:


▲ Metal material, 2205 stainless steel.


The cubic stainless steel sample is embedded with a certain type of inlay material, with the purpose of sealing the five faces of the sample and leaving only one surface with a known area. The ideal state is to have no contact with the outside world except for this exposed surface& Flash; The inlay and sample should have excellent bonding and adhesion, and there should be no gaps between them and the sample during the testing process.


Then, electrochemical testing is carried out, and the test signals are feedback of current and voltage, which are converted by area. If conductive, these signals will act on the entire test sample, making the obtained data unreliable& Flash; So it is required that the inlay material be insulated.


The environment for electrochemical experiments is a high-temperature, high-pressure, and highly corrosive environment, with a temperature of 300 degrees Celsius and a pressure of over 12MPa. There is no oxygen, and the experiment is conducted in a CO2 or H2S environment, immersed in a liquid, and the experimental time is within 12 hours& Flash; So the inlay material should be resistant to high temperature, high pressure, acid corrosion, and stable physical and chemical properties.


In electrochemical experiments, there is no significant requirement for hardness, as long as there is sufficient rigidity to withstand pressure.


The sample that has completed the electrochemical experiment is best reused if it can be reused. If it cannot be reused, it may affect the results of the next round of research and will not be reused again& Flash; So inlay materials can ignore the issues of aging resistance and service life.


Phenolic resin hot pressing inlay powder scheme, Aluminate room temperature inlay scheme and siloxane (two-component RTV) room temperature inlay scheme failed to meet the test requirements in comparative experiments.


The EpoPowder F glass filled epoxy resin hot pressing inlay powder from QMAXIS met the experimental requirements in four rounds of testing.

EpoPowder F glass filled epoxy resin hot pressing inlay powder imported from QMAXIS from the United States, in a delicate powder shape, can better bond with the sample and seal well during the hot pressing inlay process; Glass fillers are very corrosion-resistant. These characteristics determine that the EpoPowder F thermal inlay powder of QMAXIS can meet various technical requirements for electrochemical testing, making it the best choice for sample inlay materials in electrochemical testing. Choose it for embedding samples for electrochemical testing under high temperature, high pressure, and corrosive environments!
