The mixing insert is configured to receive the first and second adhesive materials from the valve body for intermixing upstream from the insert end. The dispenser further includes a nozzle that is supported relative to the support structure and arranged about the tube end and the insert end. The nozzle has an opening at a terminal end, and a shaped aperture adjoins the opening. The nozzle is configured to dispense intermixed adhesive through the opening and aperture onto a component.

A container with two inner chambers (6, 7) running in its longitudinal direction and separated by at least one partition wall. An aerobic adhesive is stored in one inner chamber (6). A hydrophilic, gel-like activator is stored in the other inner chamber (7); a mixing unit can be attached to the front end of the container. The aerobic adhesive is fed to the mixing unit from the first inner chamber (6), and the hydrophilic activator is fed to the mixing unit from the second inner chamber (7), in a specified mixing ratio via a supply device and mixed together there. This mixture is discharged via an outlet opening (13) of the mixing unit.

The present disclosure relates to a process to produce aqueous dispersions of graphene stabilized by cellulose, offering an alternative to the current methods of dispersion of graphene. The present process provides the advantages that it uses biodegradable cellulose compatible with the environment and can be used in industrial processes in alkaline medium or in the absence of alkali; and when graphene is stabilized with cellulose in alkaline medium it becomes unstable when in contact with natural waters, thus precipitating and being easily removed or concentrated. In other embodiments, solids obtained by drying of the dispersions, once dried, can be redispersed in aqueous alkaline solution.

A mixing impeller (10) for mixing a sealant inside a cartridge (1) is disclosed. The mixing impeller (10) comprises a central hub (11) and at least two mixing arms (20) extending radially outward from the central hub (11). Each of the mixing arms (20) may include a leading edge (24), a trailing edge (26), and a wiping edge (28) extending circumferentially between a leading tip (25) of the leading edge (24) and a trailing edge transition (27) of the trailing edge (26). The wiping edge (28) may have an arc length defining a wiping edge (28) angle, the leading tip (25) may be circumferentially offset in a direction of rotation of the mixing impeller (10) defining a leading edge (24) angle to provide a forward swept configuration, and the wiping edge (28) angle may be greater than the leading edge (24) angle. A sealant cartridge (1) and mixing impeller (10) assembly is also disclosed.

A storage and mixing device includes a mixing compartment, two pistons that each extend from the mixing compartment and end in a displacement section, each piston defining a passageway having a first opening communicating with the mixing compartment and a second opening communicating with an inlet at the displacement section, and a housing having two piston guides and a cartridge compartment connected to the piston guide, each piston guide slidably receiving one of the pistons, and each cartridge compartment receiving a removable cartridge that includes a cavity for containing separate substances and an opening sealed by a cartridge seal. The displacement section of each piston includes a piercing member for piercing the cartridge seal of the cartridge arranged in the corresponding cartridge compartment, such that the displacement section enters the cartridge cavity and displaces the contained substance into the mixing compartment via the inlet and the passageway.

An application device for materials, in particular adhesives, including at least one cartridge receiving device for receiving a replaceable cartridge which contains a material and has a material outlet opening; a rotary device for metering or mixing the material, rotary device having a first engagement element; a drive device for driving the rotary device, the drive device having a rod which is mounted in a rotatable and axially movable manner and has a second engagement element at the end face; and a gearing unit for driving the rod in order to bring the first and the second engagement element into engagement with each other.

The invention relates to a process for hot application of an adhesive composition (80) on a support (96), by means of a system comprising: a nozzle (50) for applying the adhesive composition (80), a line (88) for supplying the nozzle (50) with the adhesive composition (80) to be applied in fluid form, a mixer (30) positioned in the line (88) for the homogeneous mixture of the main components of the adhesive composition before its application; the applied adhesive composition (80) including as main components: a silylated prepolymer, a compatible tackifying resin; the adhesive composition comprising a cross-linking catalyst; the process comprising: supplying the line (88) with the silylated prepolymer separated from the cross-linking catalyst, the mixing of the cross-linking catalyst with the main components by means of the mixer (30), the hot application of the mixed adhesive composition (80) onto a support (96).

An adhesive composition contains a block copolymer hot melt adhesive and a vapor releasing vapor corrosion inhibitor mixed with the block copolymer hot melt adhesive, the vapor corrosion inhibitor being in the form of particles suspended in the adhesive composition, the particles preferably having a maximum dimension of less than about 30 microns. One improvement results from inclusion in the adhesive mixture of a titanium and/or zirconium containing coupling agent, either separately or as part of the VCI particles. Another improvement results from blending the adhesive mixture in a continuous process using for example a twin screw extruder. As a result, the adhesive mixture has better uniformity and superior viscosity properties during use.

Apparatus that mixes non-homogenous fluid. A threaded shaft within a housing circulates fluid within a container to effect mixing. In one embodiment, when placed in a container of fluid, the housing the fluid is recirculated through opposing ends of the housing. In an embodiment of a related method for mixing, a pump housing containing a screw journaled for rotation receives fluid within a container and conveys the fluid therethrough to circulate a fluid portion in the container along an exterior surface of the housing for mixing with another fluid portion to improve fluid homogeneity. After mixing, the portion of the fluid which first circulates through the housing may recirculate through the housing with said another portion of the fluid. The fluid may be continuously mixed and recirculated through the housing.
