Abstract: PURPOSE:To provide a method for forming the polyolefin foam rich in compressive stress and small in permanent compressive strain. CONSTITUTION:The method for producing polyolefin foam comprises filling a primary metal die with a foaming composition containing polyolefin, a cross- linking agent and a foaming agent, heating the primary metal die under a pressure of at least 50kg/cm<2> to decompose a portion of the foaming agent at such a decomposition ratio as to satisfy the formula expressed as regards a first foaming process, i.e. foaming agent decomposition %=(9 to 12)X(100/final expansion ratio), to thereby induce the foaming, thereafter releasing pressure from the primary metal die maintained at a high temperature to effect a primary expansion of the foaming agent, removing the expanded mass from the primary metal die as an intermediate foam, subsequently placing the intermediate foam into a secondary metal die having the size and shape corresponding to those of a final foam, heating the intermediate foam under normal pressure to decompose the residual foaming and cross-linking agents and effect a secondary expansion thereof, thereby producing the final foam (having an average foam diameter of 250-450mum and a continuous foam ratio of 5-20%).

Filed: 1988-11-30
Abstract: PURPOSE:To reduce noise drastically by controlling the heating operation under the condition on which the on-time of a switching means is adjusted to a specified value when an input setting value is below a specified value. CONSTITUTION:A heating means 7 for heating an object to be heated by causing an eddy current in the object to be heated by means of magnetic flux generated by electromagnetic induction heats the object to be heated with a heating output commensurate with the on-time of a switching means 13. Input setting means 31, 33, 35 for setting input for heating an object to be heated are provided. When the values of the input setting are below a specified value, a heating period during which the switching means 13 repeats on-off operations while controlling the on-time of the switching means to a specified constant value, and a resting period are set. The ratio of the length of the heating period to the length of the resting period is controlled according to the input setting value. Thus the oscillation frequency of the switching means 13 is set to a constant value. As a result, noise can be reduced and the power loss can be reduced.
