The reaction components are supplied from storage containers 1, 2 through injection nozzles 7, 8 by pumps 5, 6. As shown the remixing system &c is formed in one part of the mould, the other part comprising a plane surfaced cover. Alternatively the system may be formed in both parts of the mould. In Fig. 3 (not shown) the remixing system comprises a series of barriers 33 formed in a sprue section 30. Fig. 4 shows a further embodiment comprising two mould parts 37, 38 hinged at 39. The remixing system 46 comprises two sections 50, 51 in the form of replaceable inserts 58, 59. In the section 50, an outlet 45 from a mixing chamber 44 opens into a distributing channel 52 connected by mixing channels 53 to a collecting channel 54. The section 51 comprises a distributing channel 52 connected by mixing channels 56 to a collecting channel 57. When the mould is closed the channels 53, 56 cross over one another. Channels 56 increase in cross section in the direction of flow while channels 53 decrease. In another embodiment the mixing channels have the same cross-sectional area but differ in depth and width over their length.

摘要： This invention is directed to a process and apparatus for mixing a pulverulent or small particle size additive into at least one of the liquid reaction components for the preparation of a reaction mixture which forms a solid substance or a foam, wherein the reaction components are introduced into separate chambers and subjected to turbulence by stirring and the pulverulent additive is stirred into at least one of the reaction components and that liquid reaction component charged with the additive is transferred into a second reaction component and mixed therewith. The liquid reaction component to which the pulverulent additive is to be introduced is charged into a closed chamber to a predetermined fill level, the chamber is sealed off and a vacuum is applied above the fill level, then the additive is introduced into the chamber below the liquid level by means of the vacuum and is uniformly distributed within the liquid reaction component by the turbulence produced by stirring, while the reaction component and the additive are freed from the air carried with them by the degassing effect of the vacuum.

摘要： Foamed articles are moulded by mixing >=2 reactive components and a blowing agent (I) and introducing into a mould (I) has a b.pt. of 15-60 degrees C at 760 mm/Hg and the temp. of the mixt. is maintained >=5 degrees C above the b.pt. of (I). (I) produces high quality integral foams and can be used in pre-foaming processes. It is esp. suitable for rigid polyurethanes. Suitable (I) include CFCl3, CH3Cl, CCl4, 1,1,2,2-tetrafluoro-1,2-dichloroethane, 1,1,2-trifluoro-1,2,2-trichloroethane, acetone, diethylether and cyclopentane.

摘要： A process is described for the production of optionally cellular polyurethane moldings with an elevated ground material/filler content, which process broadly comprises a) mixing and reacting an aromatic dior polyisocyanate with a di- and/or polyol of a molecular weight of 1,000 to 20,000 in a quantity insufficient to react with all the NCO groups to yield an isocyanate pre-adduct with an NCO group content of 5 to 32%, b) mixing this isocyanate pre-adduct with ground material/filler, c) mixing the resultant mixture, with a di- and/or polyol with a molecular weight of 62 to 2,000 (crosslinking agent), and optionally water and/or an organic blowing agent, in a static mixer and d) introducing the resultant mixture into a mold.
