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.

An apparatus for producing nano-bubbles in a volume of liquid is described. The apparatus includes a motor having a rotatable shaft, an axially rotatable permeable member couplable to a gas inlet, and a rotatable tube support coupled to the rotatable shaft of the motor and having an inner cavity that houses the axially rotatable permeable member. When rotated, the axially rotatable permeable member is rotated so that the surface velocity of the rotatable permeable member simulates axial turbulent flow above the turbulent threshold in the liquid that allows the liquid to shear gas from the outer surface of the axially rotatable permeable member, thereby forming nano-bubbles in the liquid.

A screw element which has an axially asymmetrical screw cross-sectional profile which has at least two construction points located within the screw cross-sectional profile is provided. The screw element is suitable for use in an extruder having two drive shafts which rotate in the same direction and at the same speed, in order to process or produce plastic masses as an extrudate. Also, an arrangement of two identical or different screw elements in an extruder having two drive shafts which rotate in the same direction and at the same speed is provided. An extruder which is equipped with two identical or different screw elements and has two drive shafts which rotate in the same direction and at the same speed is provided. Furthermore, the use of the screw element according to the invention for processing or producing plastic masses is provided.

The present invention relates to a single-stage process for the production of starch blends in a twin-screw extruder or two twin-screw extruders arranged in series, where i) the starch, together with a plasticizer, passes through a wetting section of length 8D to 30D in an extruder or in a wetting section of length 8D to 80D if two extruders are used at temperatures below the gelatinization temperature of the starch, with mixing, where D is defined as the screw diameter of the screw cylinder and the wetting section is defined as starting at that point on the extruder screw at which the starch and the entire or partial quantity of plasticizer encounter one another and ending at that point in the extruder at which the starch is gelatinized and is digested to give thermoplastic starch; ii) in a plastifying section of length 10D to 50D the extruder temperature is adjusted stepwise to above 130° C., where the starch is digested, destructured and thermoplastified, and is dispersed in a starch-immiscible polymer, and a water content below 5%, based on the starch blend, is established before the material leaves the extruder; where the starch-immiscible polymer is added in molten or granular form at any desired point in the extruder, and a mixture of all of the components present is consequently produced.

A mixer for recirculating ash from solid fuel combustion with hydrated lime and water and to feed the mixture into a desulfurization reactor. The mixer includes a housing having a front wall, two outer vertical sidewalls, a rear wall, a top, and a bottom, the top includes a feed chute configured for the entry and addition of product to the mixer, and the front wall includes an opening for the mixture of product to exit. The mixer also includes a rotatable vertical shaft having an impeller, the impeller having a plurality of blades disposed on the vertical shaft in the same horizontal plane and distributed equidistantly about the circumference of the vertical shaft. The mixer also includes a vertical wall disposed within the housing forming a mixing region and a feeding region that is operably connected to the opening of the front wall.

A continuous production device and method for a silane-modified sealing material are provided. The device includes a twin screw extruder set, a cooling unit, and a static mixing unit; where the twin screw extruder set includes at least two twin screw extruders in series, each of which is provided with at least two inlets and at least one vacuum port, the cooling unit is disposed between last two stages of the twin screw extruders, and an outlet of a last-stage twin screw extruder is connected to the static mixing unit. Through the arrangement of various units of the device and their positional relations, components can be mixed in sequence or added in stages, so as to adapt to the characteristics of each component; a heat stabilizer and a polymer are added together as raw materials, which can increase the temperature for dehydration and avoid thermal decomposition of the polymer, and they cooperate with a dehydrant to make water in the system easier to remove; and the device has high operation flexibility and can adapt to the requirement of variability of a formulation of the silane-modified sealing material.
