Polyurethane production line

automatic

With the growing popularity of plastic industry, PU adhesive as a new generation of adhesives, its scope of application is also more and more widely, such as aircraft, car interior parts seats, shoes, outsole and so on. It has excellent adhesion fastness, good heat and weather resistance, colorless and translucent, environmentally friendly non-toxic, easy to operate, suitable for assembly line production. What are the components of Polyurethane Adhesive? Polyurethane adhesive common ingredients include polyols, isocyanates, catalysts, and additives. Equipment List: ▪ Reaction kettle ▪ Condenser ▪ Dispersing kettle ▪ Filter ▪ Filling machine ▪ Steam furnace ▪ Water cooling system ▪ Material pump PU Adhesive Production Line specifications: 1) 500L-1500L PU Adhesive Production Line; 2) 2000L-3000L PU Adhesive Production Line; 3) 4000L-6000L PU Adhesive Production Line; It can be dsigned according to the actual needs. Mixing Accurate metering and mixing of raw materials are crucial to the quality of the adhesive. Typically, raw materials are measured and pumped into a mixing vessel. The mixing vessel combines the raw materials under controlled conditions, including temperature and pressure. This process initiates the chemical reaction that forms the polyurethane adhesive. Reacting The mixture is transferred to the reactor kettle, where the chemical reaction continues to take place. The reaction conditions, such as temperature and dwell time, are closely monitored to achieve the desired adhesive properties. During this phase, the polyurethane adhesive undergoes polymerization, leading to the formation of a viscous liquid.
