The present invention concerns a method and a plant for the production of polymeric adhesives comprising the steps of dosing of the base material into a mixer (31) by means of a first metering device (11), dosing of the catalyst material into the mixer (31) by means of a second metering device (21), mixing the base material and the catalyst material in a mixture by means of the mixer (31), packing the mixture in storage containers. Moreover, the method of manufacturing comprises a step of managing a first temperature, by means of first temperature control means of the base material and catalyst material, wherein the base material and the catalyst material are kept within a predetermined range of temperature such as to prevent the formation in the mixer (31) of the polymeric adhesive in an oligomeric state. Furthermore, the method of manufacturing comprising a step of managing a second temperature, by means of second temperature control means of the mixture, wherein the mixture is kept within the predetermined range of temperature such as to prevent the formation in the storage containers of the polymeric adhesive in an oligomeric state. Finally, the method of manufacturing comprises a step of cooling the storage containers able to slow down the formation in the storage containers of the polymeric adhesive in an oligomeric state.

A re-mixing dispenser for containing and dispensing a liquid. The dispenser may have one or more tubes, each containing a different liquid. At least one of the liquids may be re-mixed in situ, using a special two-piece plunger and plunger rod. A mixing piece of the two-piece plunger is moveable independently of a top piece and has blades that allow it to move through the liquid. A plunger rod is removably attached to the mixing piece and is operable to move the mixing piece up and down within the tube during mixing. The two plunger pieces are joined and moved as a single plunger during dispensing.

Disclosed is an automatic sealant production line, including a sealant preparation apparatus and a packaging apparatus. The sealant preparation apparatus includes a material storage device, a liquid storage device, a material sending device, a lateral material feeding device, a first-order screw unit, a first liquid feeding device, a heat exchanger, a second-order screw unit, a pigment feeding device, a cooler and a buffer tank device. The packaging apparatus includes a filling device and a packaging device.

A dynamic mixer dispense valve and metering apparatus suitable for use in mixing and applying high viscosity, disparate viscosity, high ratio, and/or relatively immiscible two part compounds that exhibit short cure times includes a housing supporting a pair of valve assemblies each coupled to respective sources of base and accelerator components. A pair of pneumatic valve actuators control the operation of the valve assemblies to control the flow of components into a mixing chamber. Within the mixing chamber a mixer impeller is rotatably supported and coupled to a source of rotational power. An additional pneumatic valve actuator combination operates a further flow control to prevent undesired material loss following a shot cycle.Note

The invention relates to a multiple-chamber container (1, 1*) for storing and mixing a multi-component liquid coating or adhesive system (M), comprising a first chamber (10) for a first mixing component (B) and at least one other chamber (20) for another mixing component (H), the first chamber (10) and the at least one other chamber (20) being separated by at least one separating wall (30) in liquid-tight fashion and the separating wall (30) comprising a pierceable separating layer (40). The multiple-chamber container further comprises at least one piercing element (50) for piercing the pierceable separating layer (40) in such a way that the first and the one other mixing component (B, H) mix in the first or the at least one other chamber (10, 20). The multiple-chamber container (1, 1*) is characterized in that the at least one other chamber (20) is coaxial to the first chamber (10), the separating layer (40) being partially formed in the separating wall (30). The piercing element (50) is hollow, in particular hollow-cylindrical, and has at least two longitudinally offset openings (51) for introducing either the first or the other mixing component (B, H) into the chamber (10, 20) of the respective other mixing component (H, B).

An attachment element for a static mixer and an attachment system with such an attachment element, the static mixer, and a pressure sensor. The attachment element has a flow channel with an inlet opening and an outlet opening arranged opposite the inlet opening in a longitudinal direction of the flow channel and designed as an injection nozzle. The attachment element is designed to be fastened at an inlet side having the inlet opening by a fastening unit of the attachment element on top of an injection tip of the static mixer. Furthermore, the attachment element has a receiving opening for the pressure sensor. The receiving opening extends from an exterior side of the attachment element to an opening in a subsection of a channel wall of the flow channel.

The invention relates to continuous methods for compounding and applying adhesives, characterized in that (i) a base component of the adhesive is mixed continuously with at least one aggregate so as to produce a compounded adhesive; and (ii) the adhesive compounded in this manner is applied to a substrate. The invention also relates to such methods where a device as described here is used to carry out the method.

A two-component adhesive system pumps a first adhesive component and a second adhesive component into a replaceable mixing unit that can be periodically replaced when the adhesive has cured in the mixing unit. The adhesive system may have a robotic arm coupled to a gripper unit which has an open configuration and a closed configuration. In the open configuration, the gripper unit releases the mixing unit allowing the mixing unit to be replaced. The robotic arm may moves the gripper unit to install a replacement mixing unit. The gripper unit can be moved to the closed configuration and the adhesive can be pumped through the mixing unit.

The present invention is an integrated at least two component system and method which combines at least two or more components and creates at least one new mixture. This system contains at least one first component in a first, optionally sealed, container and at least one second component in a second sealed container that is contained in or adjacent to the first container. Both components can be in a single container sealed off from each other. This system enables the mixing of these components to produce a new mixture, and then enables the application of this new mixture to be applied on at least one surface
