Temperature variation of polyurethane foaming machine during operation

Polyurethane foaming machine The production of foam is dependent on heat, so the temperature and high - pressure foam machine contact. Without heat, the foaming agent in the system cannot evaporate and form foam. When the ambient temperature is high, the environment can provide heat to the reaction system, which can increase the reaction speed and shorten the reaction time. The foam machine has sufficient foam, and the density of foam surface and core is close to each other. When the ambient temperature is low, part of the reaction heat is dispersed into the environment, resulting in the loss of heat. As a result, the foam maturation period is prolonged and the foam forming shrinkage rate is increased.

For the same foaming material, the foaming volume at the ambient temperature of 15℃ is 25% smaller than that at 25℃. In addition, a layer of hard skin without sufficient foaming or even non-foaming will be formed on the foam surface, which increases the amount of foam perfusion, improves the foam production cost and reduces the enterprise benefits. So the temperature is zero Polyurethane foaming machine Efficiency plays a big role, we should pay attention to this point in daily operation.
