Working principle of sandblasting machine

The freeze sandblasting machine utilizes the low-temperature freezing effect of liquid nitrogen to embrittle rubber and plastic alloy materials. At this time, the burrs become brittle before the product. Within the time difference between the burrs becoming brittle and the product not yet becoming brittle, a polymer particle is sprayed at high speed to impact the burrs of the product and high-quality remove the burrs of rubber and plastic alloy products as well as aluminum and zinc alloy products.

Rubber and plastic alloy materials belong to polymer materials, and they will be in different phase states at different temperatures. From the perspective of phase state, the material is only a change in mechanical state. When the material is under low temperature conditions, its state changes. When it returns to normal temperature conditions, all properties will be restored.

The physical properties of rubber plastic alloy materials occur as the temperature decreases:

Hardening, embrittlement, vitrification

After the temperature drops, the rubber plastic alloy material begins to harden and will not deform or be damaged below the embrittlement temperature. After being restored to room temperature, its physical and chemical properties will not change.
