AI Technical Summary
In the production process of styrene-butadiene latex, the entry of cold materials into the reactor causes local temperature fluctuations and premature reactions, affecting the reaction rate and product consistency, and reducing production safety.
A preheating device for feeding the reactor is adopted. The material is conveyed into the reactor body through the feeding component and preheated. Combined with the stirring of the stirring rod, the material is preheated by the heating rod and the controller. The material is evenly dispersed into the reactor body by the U-shaped tube and the distribution tube to avoid local temperature fluctuations and premature reaction.
It effectively improves the uniformity of material temperature, avoids local temperature fluctuations and premature reactions, and enhances product safety and consistency.
