摘要： Appts. for continuous prodn. of foam blocks with a rectangular cross section from an expansible reaction mixt. has a circulating conveyor belt and side defining belts consisting of single units in which the gripping devices for the side films are guided for reciprocating movement. Continuous prodn. of rectangular foam blocks, esp. from polyurethanes, is obtained without the need for additional side films. No machine part contacts the foaming mixt., and the side edge zones of the blocks are undamaged.

摘要： In the production of foamed articles wherein the foam producing reaction occurs between the belts of a double belt conveyor and the double belt conveyor serves as a mold, the pressure of the foaming reaction of the belts is sensed and, to obtain a uniform structure in the product, the feed rate of the components reacting to from the foam, per unit area of the belt, is correspondingly varied.

摘要： A process for producing polyurethane foam comprises applying a froth on to a transport band of a block foam unit. The froth is dropped vertically on to the lower transport band. The froth is prevented from flowing against the direction of transport band movement, by a fixed, lateral vertically arranged barrier.

摘要： A process for producing foam from two-component reactive plastics comprises: (a) mixing at least one of the reactive components with CO2 under pressure; (b) thereafter mixing the components; (c) expanding the resulting reaction mixture suddenly with the prodn. of high rates of shear; and (d) hardening the expanded mixture. A device for producing foam (15) comprises a mixing appts. (11) for mixing two components, at least one of which contains CO2 under pressure, the outlet of the mixing appts. having an opening (12)

摘要： Producing foam from a liq. contg. gas dissolved under pressure, by expanding the liq. to a pressure below the satn. pressure of the gas and releasing the gas. The process comprises forcing the liq. through an extended flow channel so that the pressure is reduced against the flow resistance and a high shear rate is generated, and then reducing the rate of flow to 1/10-1/500 of its original value before the liq. foams. Also claimed is an appts. for this process, comprising a housing (2) contg. a long flow channel (4) with a small cross-section in at least one dimension, a distribution chamber (5) for the pressurised liq. over the opening(s) of the flow channel, a feed pipe (7) for the distribution channel (5) and a means (6) of reducing the speed of the liq. after the outlet end (15) of the flow channel (4). Pref. used esp. for the prodn. of foam from 2-component reactive plastics with CO2 as blowing agent, the process comprises mixing at least one of the components with CO2 under pressure, mixing the components, expending the CO2-contg. mixt. and hardening the foam obtd.. The liq. or reactive mixt. passes through the flow channel in less than 10 2 secs., and the shear rate produced in the channel is at least 10 4/sec.. The flow channel is in the form of a conical ring channel with an inner cone which can be moved axially to narrow the channel. The ratio between the length of the flow channel in the direction of flow and its small cross-sectional dimension is 30-300.
