Stirred-tank reactor

for industryfor the chemical industryfor medium-viscosity liquids

Overview
Hot melt glue production line reactor is used for resin polymerization, modification reactions, melt mixing and formulation to ensure stable product viscosity, uniform molecular weight and stable thermal properties. It supports flexible switching between formulations and is suitable for continuous production.

Applications

• Packaging hot melt adhesives
• Pressure-sensitive label adhesives
• Bookbinding adhesives
• Medical hot melt adhesives
• Adhesives for bandages
• Industrial assembly adhesives

System characteristics

• Processed materials typically have high viscosity
• Operation at elevated temperatures
• Raw materials may oxidize easily
• Products tend to generate bubbles and require degassing

Reactor features

• Forced stirring structure (inclined paddle + anchor + ribbon)
• Precise temperature control and zoned heating
• Insulated conveying design to maintain temperature
• Designed for stable product quality and easy formulation changeover

Equipment configuration

• Automatic raw material feeding system
• High-temperature thermal oil heating system
• Reactor
• Vacuum degassing system
• Filtration system
• Insulated gear-pump conveying system
• Granulation/block forming system
• Automatic packaging system
• PLC automatic control system
