Product Introduction
This product is a high-performance diamond wire cutting fluid mainly used for processing solar-grade silicon rods. The product features excellent cooling, wetting, dispersion, defoaming and cleaning properties, and is compatible with single-cylinder or circulation system cutting modes, matching the cutting processes of silicon wafers of different specifications.
Product features
- Cooling performance: Enhance the mass transfer rate of materials and rapidly reduce the temperature at the contact surface between diamond wire and crystalline silicon.
- Cleaning performance: Promotes the removal of silicon powder from the surface of diamond wire and silicon wafers, maintaining good cleanliness of the cut wire mesh and silicon wafers.
- Dispersion performance: Reduce the loss of wetting agents and inhibit the aggregation of silicon powder in the cutting silicon body.
- Lubrication performance: Reduce the friction between the diamond wire and the silicon wafer, and decrease the wear degree of the diamond wire.
- Anti-rust performance: Inhibits the corrosion of equipment and diamond wires.
- Stability performance: The effective components do not undergo chemical decomposition in the return water system, and the relative proportions of each component remain relatively fixed.
- Defoaming performance: Accelerate the defoaming rate of the foam in the internal diluent of the silicon body and solve problems such as cylinder overflow.
