摘要:
Eine Filtriervorrichtung (100) umfasst: ein verschiebbar im Gehäuse (30) gelagertes, zylinderbolzenförmiges Siebträgerelement (10), das jeweils mehrere Siebräume (11.1, 11.2; 12.1, 12.2) aufweist, in welchen jeweils ein Filterelement angeordnet ist, einen Eintrittskanal (31.1, 31.2, 32.1, 32.2) und einen Austrittskanal (41.1, 41.2; 42.1, 42.2) im Gehäuse (30) die in einer Produktionsstellung jeweils mit wenigstens einem Siebraum in Verbindung zu bringen sind. Um die wirksame Filterfläche zu erhöhen, sind wenigstens zwei Paare von Siebräumen am Siebträgerelement vorgesehen, wobei die Siebräume jedes Paares diametral gegenüberliegend am Siebträgerelement angeordnet sind und wobei innerhalb des Siebträgerelements keine Verbindung unter den Siebräumen besteht. Zwischen den Austrittskanälen im Gehäuse und den Siebräumen ist jeweils wenigstens ein sich in Richtung der Längsachse (19) des Siebträgerelements (10) erstreckender Zwischenkanal (13.1, 13.2, 14.1, 14.2) vorgesehen. Bei jedem Paar von Siebräumen sind Zwischenkanäle unterschiedlicher Länge vorgesehen.
摘要:
A dynamically vulcanized alloy containing an elastomer and a thermoplastic resin is prepared by a process wherein supercritical fluid is injected into the thermoplastic elastomeric material as the material is mixed in an extruder. The material is mixed under conditions such that the thermoplastic elastomeric material is dynamically vulcanized wherein the elastomer forms a discontinuous dispersed of small particles in a continuous phase of the thermoplastic resin. The DVA material may then be directly formed into film or sheets by the use of at least one set of rolls located adjacent to the extruder outlet.

The invention relates to a mixing device comprising at least one screw injection moulding machine (S1) and a screw injection moulding machine (S2). (S1) is provided with heating devices at least in the plasticising and homogenising section, and the outlet pertaining to (S2) is connected to the screw cylinder of (S1) in the plasticising or homogenising section pertaining to (S1). It is essential that (S1) and (S2) are connected by means of a connecting device provided with a cooling device which acts up to the inner wall of the screw cylinder of (S1). The invention also relates to methods for producing thermoplastically processable moulding materials, especially additive batches, consisting of at least one thermoplastic component (K1) and at least one component (K2). The melting or decomposition temperature (TS ) of (K2) is at least ca. 50 DEG C lower than the temperature (TW ) which limits the lower end of the thermoforming range of (K1), (K2) only largely being melted after coming into contact with (K1).

摘要:
The invention relates to an apparatus for coextruding polymers at different temperatures comprising at least two extruders (1, 2), wherein the extruders are connected to a coextrusion head (4) which comprises an insulation zone (40), and at least one of a cooling zone (21) and a heating zone (31) and wherein a removable die/dieholder-combination is mounted to the coextrusion head (4). The invention also relates to a method for coextruding two or more polymers at different temperatures by shaping the polymers independently of one another, until the moment they meet at the vicinity of the die-frontplate (13), where the polymers are brought together and a coextrudate is formed.
