摘要： A system for generating and dispensing plural component materials includes a controller operatively connected to dispense valves and return valves. The return valves are in respective open states to allow constituent materials to circulate back to a source and are in respective closed states to block circulation. The dispense valves are in respective open states to allow mixing of the constituent materials to form the plural component material and in respective closed states to prevent generation and dispense. The controller implements a delay between closing the return valves and opening the dispense valves to build pressure in the system prior to generating and dispensing the plural component material.

摘要： A composition and a method are provided for graphene reinforced polyethylene terephthalate (PET). Graphene nanoplatelets (GNPs) comprising multi-layer graphene are used to reinforce PET, thereby improving the properties of PET for various new applications. Master-batches comprising polyethylene terephthalate with dispersed graphene nanoplatelets are obtained by way of compounding. The master-batches are used to form PET-GNP nanocomposites at weight fractions ranging between 0.5% and 15%. In some embodiments, PET and GNPs are melt compounded by way of twin-screw extrusion. In some embodiments, ultrasound is coupled with a twin-screw extruder so as to assist with melt compounding. In some embodiments, the PET-GNP nanocomposites are prepared by way of high-speed injection molding. The PET-GNP nanocomposites are compared by way of their mechanical, thermal, and rheological properties so as to contrast different compounding processes.

摘要： A kneading state detection device includes an acquisition unit that, when an extrusion molding machine that kneads a raw material or kneads a raw material and an additive is in operation, acquires an output of an AE sensor installed on a housing of the extrusion molding machine, and a determination unit that determines a kneading state of the raw material, based on a comparison between a change in intensity of the output of the AE sensor acquired by the acquisition unit and a threshold.

摘要： Apparatuses for producing and dispensing a reaction mixture include a mixing head for mixing the reaction components that are fed via two supply lines. The apparatuses also include a decompression system to relieve pressure from the supply lines to avoid the reaction components seeping into the mixing head. The decompression system includes two pressure vessels each with two sides, separated by a membrane. One of these sides forms an expansion chamber for the reaction component while the other side is connected to a pneumatic system. With this pneumatic system, the expansion chamber can be pressurized before the production of the reaction mixture is started. After the production of the reaction mixture, the pressure can be relieved.

摘要： A production device for melt-blown non-woven fabric, with which a high molecular weight polymer can be reduced in molecular weight by applying a shear force to the high molecular weight polymer without adding an additive such as a peroxide that promotes thermal decomposition reaction, and a low molecular weight polymer can be efficiently produced. The low molecular weight polymer and the melt-blown non-woven fabric are produced using a continuous high shearing device that applies a shear force to the high molecular weight polymer serving as a raw material by rotation of a screw body 37 to reduce the molecular weight of the high molecular weight polymer so as to obtain a low molecular weight polymer, and cools the low molecular weight polymer by passing the low molecular weight polymer through a passage 88 arranged in the axial direction inside the screw body 37.

摘要： Provided is an electrically conductive resin composition with which the characteristics inherent in a thermoplastic resin are easily retained and which exhibits more excellent electrical conductivity even if the blending amount of an electrically conductive filler is small. This electrically conductive resin composition contains a thermoplastic resin, such as a polycarbonate or a polyolefin, and an electrically conductive filler, such as a carbon nanotube. This electrically conductive resin composition further contains a dye, such as a perinone-based dye or a disazo-based dye, which is a component for improving electrical conductivity, and this electrically conductive resin composition can be obtained by kneading or molding a raw material mixture containing a thermoplastic resin, an electrically conductive filler, and a dye under a condition of a temperature equal to or higher than the melting point of the thermoplastic resin.
