Effectively solve the polyurethane resin materials difficult to uniform mixing problems.
So it has difficult to mix two-component materials uniform problems, which will affect final Products quality.
The uniformity of two component materials is difficult to determine during actual experiment.
This materials belongs to high polymer materials.Thus, while using two component materials, the mixing may be not uniform.
Periodically altering the stirring speed can strength the mixing of two component materials.
