    摘要: Apparatus (10) for incorporating blowing agents into a liquid material provides a high pressure liquid storage and mixing tank (20) containing a mixture of liquid material (M) under pressure; means for delivering (59) a pre-determined quantity of at least one blowing agent into the mixture in minute bubbles having an average diameter of from about less than 0.5 micron up to about 100 microns; and means for uniformly distributing (60) the blowing agent throughout the liquid material. Apparatus (100) for measuring the volumetric expansion potential of a mixture of blowing agent and liquid material is also provided. It includes a high pressure liquid storage and mixing tank (106) containing a mixture of liquid material (M) and at least one blowing agent under pressure; first and second chambers (140, 141) communicating with each other and with the tank; first and second means for transferring (142, 143) the mixture into and out of the first and second chambers; and first and second means for measuring (144, 145) the volumes displaced by the mixture in the first and second chambers, wherein the second measuring chamber has a volume at least one order of magnitude greater than the first chamber. Finally methods are provided for use of the foregoing apparatuses.

    摘要: Apparatus (10, 180, 260, 270) for incorporating blowing agents into a liquid material provides a high pressure liquid storage and mixing tank (20, 181, 261, 271) containing a mixture of liquid material (M) under pressure; means for delivering (59, 220, 232, 285) a pre-determined quantity of at least one blowing agent into the mixture in minute bubbles or droplets having an average diameter of from about less than 0.2 micron up to about 100 microns; and means for uniformly distributing (60, 110, 237, 276) the blowing agent throughout the liquid material. Apparatus (100, 260, 270) for measuring the volumetric expansion potential of at least one blowing agent and a liquid material component (M) within a closed system comprises a high pressure tank (106, 181, 261) containing liquid material and at least one blowing agent under pressure; means for measuring (135, 240) the volumetric expansion potential of the mixture, providing first (136, 250) and second (138, 251) chambers, communicating with each other and with the tank; means for transferring (142, 143, 243) the mixture into and out of the first and second chambers, the second measuring chamber having a volume sufficiently greater than the volume of the first chamber whereby at least some of the blowing agent will leave the mixture; means for measuring (164, 252) the pressure in the first chamber; and means for measuring (144, 145, 253) the volumes displaced by the mixture within the first and second first chambers. Finally methods are provided for use of the foregoing apparatuses.
