摘要:
A mixing device (1) having at least one first feed opening (2) for at least one first liquid – preferably gas-laden – plastics component and having at least one second feed opening (3) for at least one second liquid plastics component, and having a discharge opening (4) for discharging a mixture, which can be produced in the mixing device (1), of the first and of the second liquid plastics component, wherein the mixing device (1) has a rotating agitator (7) for mixing the first and the second liquid plastics components, wherein a gap (6) remains between the agitator (7) and the discharge opening (4), wherein an adjustment device (5) is provided which either varies the gap (6) by way of a relative movement between discharge opening (4) and agitator (7) or varies the size of the discharge opening (4), and wherein a regulating device (14) is provided which is connected in signal-transmitting fashion to a sensor (17) for determining a pressure prevailing in the mixing device (1), wherein the regulating device (14) sets the gap (6), or the size of the discharge opening (4), by way of the adjustment device (5) such that the pressure prevailing in the mixing device (1) has a predetermined value.
摘要:
Vorrichtung (1) und Verfahren zur Herstellung einer gefärbten Kunststoff-Schmelze (S 1 ) und einer ungefärbten Kunststoff-Schmelze (S 2 ), umfassend eine Mehrwellen-Schneckenmaschine (2), eine erste (3) und eine zweite (4) Dosiereinrichtung und eine Steuereinrichtung (5) zum Auswählen zwischen einem ersten Betriebsmodus (B 1 ) zur Herstellung der gefärbten Kunststoff-Schmelze (S 1 ) und einem zweiten Betriebsmodus (B 2 ) zur Herstellung der ungefärbten Kunststoff-Schmelze (S 2 ), wobei die erste Dosiereinrichtung zum Zuführen eines ungefärbten Kunststoffmaterials (M) durch eine erste Zuführöffnung (16) in ein Gehäuse (6) der Mehrwellen-Schneckenmaschine und die zweite Dosiereinrichtung zum Zuführen zumindest eines Farbmittels (F) durch eine zweite Zuführöffnung (17) in dieses Gehäuse dient. Dadurch soll eine einfache, flexible und wirtschaftliche wahlweise Herstellung einer gefärbten und einer ungefärbten Kunststoff-Schmelze ermöglicht werden.

摘要:
Process and device for the production of thermoplastic moulding compounds, in particular for the production of acrylonitrile-butadiene- styrene ABS, wherein at least two reagents are fed to a rotor-stator unit (10) which comprises at least one stator (30) and at least one rotor (20) that is rotatable relative to the stator (30) about an axis of rotation (A), wherein the stator (30) has at least one stator gear ring (31) and the rotor (20) has at least one rotor gear ring (21) and the stator gear ring (31) and the rotor gear ring (21) are spaced apart from one another in a radial direction and are arranged so as to overlap in an axial direction, and wherein the reagents are dispersed to form a dispersion in the rotor-stator unit (10).
摘要:
The invention relates to a method for manufacturing a composite product comprising organic natural fiber material and matrix material, wherein the method comprises mixing the organic natural fiber material with the matrix material in a primary mixing stage to form a mixture. The primary mixing stage comprises a contacting step in which the organic natural fiber material comes in contact with the matrix material that is at least partly in a form of melt, and bulk density of the organic natural fiber material is less than 500 kg/m3. The method further comprises forming a composite product comprising the mixture. Further, the invention relates to a composite product, a use of the composite product, and a system for manufacturing a composite product.
