The present disclosure describes a composite material and a method for making the composite material. The method includes mixing a copolymer binder with a thermoplastic biopolyester polymer (TBP) at a mixing temperature of 80-280° C. to create a polymer mixture; and mixing pyrolysized organic matter and an organic filler material with the polymer mixture to create the composite material. In an embodiment, the source of the pyrolysized organic matter is post-consumer food waste, and the mixing is performed by a shear mixer that is operated at 40-100 revolutions per minute (RPM). The composite material may comprise by weight at least 35% of a combination of the pyrolysized organic matter and the organic filler material.

Provided is a kneading device that can check a progress of wear of an inner wall face of a kneading chamber provided in a casing without stopping the kneading device. A kneading device includes a sensor-mount space provided in a wall of a casing, a wear detecting sensor of which a detecting section is disposed at a bottom of the sensor-mount space, and a controller that receives a signal output from the wear detecting sensor, the controller including a wear determining unit that determines that wear of an inner wall face of a kneading chamber has progressed based on a change in the signal.

A method, apparatus, and system for mixing a compounded material. A first selected amount of a base part for the compounded material and a second selected amount of an activator part for the compounded material to form a total amount of the compounded material is determined. The first selected amount of the base part is pumped by a pump system from a set of base part sources connected to the pump system into a container. The second selected amount of the activator part is pumped by the pump system from a set of activator part sources connected to the pump system into a container. The base part and the activator part in the container are mixed by a mixing system for a predetermined amount of time that is sufficient to activate the compounded material for use.

Disclosed herein are methods of preparing composites from solid elastomer(s) and wet filler(s), as well as products, including composites, vulcanizates, and articles therefrom. The wet filler can have a liquid content of at least 15%. A resulting composite comprises the filler dispersed in the elastomer at a loading of at least 20 phr with a filler yield loss of no more than 10%, wherein the composite has a liquid content of no more than 10% by weight based on total weight of said composite.

A kneading device for dispersing a dispersoid in a dispersion medium includes a casing in which a kneading material containing the dispersion medium and the dispersoid is accommodated, a rotor disposed in the casing and kneading the kneading material while dispersing the dispersoid in the dispersion medium by rotating about a rotation axis, and a detection unit detecting a dispersion degree of the dispersoid in the dispersion medium by observing a state of the kneading material in the casing.

An example system is used to mix components and dispense a mixture for forming a thiol-ene polymer article. The system includes a first reservoir containing a first component of the thiol-ene polymer including a first polymerizable compound, and a second reservoir containing a second component of the thiol-ene polymer including a second polymerizable compound. The system also includes a mixing vessel having a mixing chamber, a delivery manifold providing a conduit for fluid from the first and second reservoirs to the mixing vessel, and a dispensing manifold providing a conduit for fluid from the mixing vessel. The system also includes a control module programmed to control the operation of the system.

A tire tread and a tire are provided, more particularly, a tire having a tread or other elastomeric component within enhanced composite material properties, including, but not limited to, modulus ratio, percent elongation at break, and/or tan delta, wherein the tire, tread or other elastomeric component comprise composites characterized by well dispersed reinforcing filler, which can be indicated by macrodispersion.

A method of forming a composite material includes mixing granules of thermoplastic(s) and granules of reinforcing material(s) using a mixer with an interior friction coating. The friction generated by interaction between the granules and friction coating causes granules of at least one of the thermoplastic(s) to be heated to a liquid or semi-liquid state. The liquid/semi-liquid thermoplastic(s) act a binder for the mixed material. A system for forming such a composite material includes such a mixer with an interior friction coating. The system may also include a mould and/or a press for forming material produced by the mixer into a finished shape. The method and system may use post-consumer and post-industrial material as an input allowing such material to be recycled. In some cases, cross-contaminated or mixed post-consumer/post-industrial material may be recycled, potentially reducing environmental impacts.

A process for producing a precursor material comprising the steps of, agitating a polymer material and a fibre material in a blending device comprising a blending means operating at a velocity sufficient to bring about an increase of the temperature to at least a temperature beyond the VI CAT softening point or within or beyond the melting temperature range of the polymer material. Thereafter, maintaining the velocity of the blending means and, when the specific motor power needed to maintain the velocity of the blending means increases by a predetermined amount or reaches a predetermined value, reducing the velocity. Repeating the previous step as necessary, until the velocity falls below a first threshold value to form an intermediate material. Finally, comminuting the formed intermediate material in a comminuting device comprising a comminuting means operating at a velocity allowing a decrease in temperature, until the temperature falls below a second threshold value.

The invention is directed to an apparatus for making a finished rubber mixture which includes a reactive additive. The apparatus includes a tandem mixer with an upper machine having an upper mixing chamber and a lower machine having a lower mixing chamber. The lower mixing chamber is larger than the upper mixing chamber and there are rotors disposed in each mixing chamber. Mixture components are introduced into the lower mixing chamber via a loading shaft of a loading unit. The loading unit has at least two metering devices, a cutting or preheating unit connected upstream of a metering device and a first conveyor belt to the loading shaft. All conveyor belts of the apparatus can be switched on and off automatically, such that mixture components weighed in can be held in a “wait position” thereon.
