A computer simulation model was established to analyze the curing and cooling of reaction injection molding process of nylon 6 based on theory of balance equation of energy, reaction kinetics and crystallization kinetics. The reasonable assumptions and simplifications were introduced in the model, and an explicit finite difference method with MATLAB software was applied to calculate and predict the conversion and temperature distribution within a plate type mold. The results show that the center position reaches the peak temperature about 45s. The effects of the feed temperature, wall temperature, and reaction rate constant on the temperature and conversion were discussed for searching the optimum processing conditions. The results suggests that the effect of reactive rate on crystallization, molecular weight and phase structure is decided by the value of reaction constant; the influence of the mold wall temperature on reactive rate and temperature near the boundary was great; and the control of feed temperature is important in condition of low mold temperature.

Phenolic Foam

Reaction injection molding process of phenolic foam sandwich plate was introduced in order to resolve the difficulties in repetitive continuous manufacturing process of such product. The phenolic foam produced here have uniform pore diameter, good fireproof property and there need not any glue between phenolic foam and color steel plate which could make it a potential building material instead of polysterol sandwich plate.
