Optimizing the production technology of eco-friendly foam polyurethane panels on the continuous line

With the preeminent features of polyurethane (PU) panels such as sound insulation, heat fireproof, high load capacity, lightweight, aesthetics, especially using simple and easy assembly construction move, so new PU panel is now first choice for projects. In this work, authors study generation physical foaming agent cyclopentane that environmentally friendly completely does not destroy ozone layer. Study investigating evaluating effect content foam on free expansion density, reaction time rigid (R-PUF), values ​​(cream time, gel tack-free rise time). The morphology size closed-cell R-PUF samples with concentrations increasing from 0% to 20% are observed by optical microscope image distribution chart determined IT3 software. addition, mechanical properties dimensional stability compressive strength were analyzed evaluate quality expanded insulation in mold a agent. Experimental procedures according Taguchi's analysis continuous production line aimed at giving optimal parameters industrial manufacturing process. research results provide an excellent reference value manufacturers further improve performance panels.
