Hot pressing inlay:


1. The surface layer needs to be thoroughly mixed with powdered resin and powder samples. It is recommended to use QMAXIS EpoPowder F/G thermosetting epoxy resin/glass filling for the surface layer.

The original imported QMAXIS hot pressing inlay powder from the United States is suitable for hot pressing inlay of materials that are not sensitive to temperature and pressure. It has good edge protection effect and is suitable for continuous batch sample preparation. Hot pressed inlay powders with different compositions, hardness, and colors can meet the inlay needs of most materials.


2. The encapsulation of resin particles and the dispersion of powder particles are not as good as cold embedding.


3. The resin has a high hardness and is more suitable for powder materials with high hardness.


Cold inlay:


1. Mix thoroughly with the resin and stir well before natural curing. It is recommended to use QMAXIS EpoQuick epoxy resin and curing agent with lower viscosity.

Original imported QMAXIS cold embedding resin and curing agent from the United States, including epoxy resin and acrylic resin. Good fluidity, low shrinkage rate, strong permeability, and good edge protection effect. Suitable for room temperature inlay of materials sensitive to temperature and pressure.


2. The resin has better encapsulation and powder dispersibility for particles.


3. When there is a significant difference in hardness between resin and powder, control the protrusion phenomenon during grinding and polishing.


Grinding and polishing:


1. Ceramic hard powders are ground using QMAXIS DGD MetBond metal bonded diamond grinding discs, while conventional powders are ground using QMAXIS CarbiPaper silicon carbide sandpaper.

The original imported QMAXIS diamond grinding disc from the United States has a long service life, high material removal rate, and can achieve ideal surface flatness and edge protection.


The original imported QMAXIS silicon carbide sandpaper from the United States has strong toughness, wear resistance, and is not easy to tear; High flatness, non curling; Good water resistance; High removal rate; Long service life. It can quickly remove the surface layer and deformation layer of the material, effectively shortening the subsequent sample preparation time.


2. When polishing, priority should be given to choosing QMAXIS PlanCloth/SatinBatch polishing cloth to avoid powder detachment.

The original imported QMAXIS polishing cloth from the United States is made of various high-quality polishing fabrics. It is a metallographic polishing cloth with different weaving properties such as velvet, short velvet, and long velvet, and is suitable for surface polishing of various materials when used in conjunction with diamond or oxide polishing solutions of different particle sizes. There are two types of backing: adhesive backed and magnetic backed, making replacement more convenient& Flash; Improve sample preparation efficiency; A smoother surface&# 8217& Flash; Laying the foundation for high-quality polishing effects.
