  • Patent number: 11498982
    Abstract: A method for concentrating rubber emulsion and a product prepared by the method are provided, the method includes: a concentrated latex is obtained by separating a superabsorbent resin added in advance into a rubber emulsion with a solid content of 0.01-70% after stirring and concentrating the resin-added rubber emulsion. The method requires simple equipment and consumes less energy, and the prepared polymer emulsion has a solid content up to 76%; the superabsorbent resin adopted herein is reusable after drying, which therefore effectively reduces the production cost; natural latex concentrated by the method has rather high yields of dry rubber and little wastewater production; products prepared from the concentrated natural latex have excellent mechanical property, aging resistance and adhesive property; and concentrating natural latex according to this method does not require advance agglomeration, which reduces the production procedures and improves the production efficiency significantly.

  • Patent number: 11493847
    Abstract: The present invention relates to a structure for a quantum dot barrier rib and a process for preparing the same. The structure for a quantum dot barrier rib of the present invention comprises a cured film having a uniform film thickness and an appropriate range of film thickness. Here, the reflectance RSCI measured by the SCI (specular component included) method and the reflectance RSCE measured by the SCE (specular component excluded) method are reduced, and the ratio between them (RSCE/RSCI) is appropriately adjusted, so that it is possible to satisfy such characteristics as high light-shielding property and low reflectance at the same time while the resolution and pattern characteristics are maintained to be excellent. In addition, when the structure for a quantum dot barrier rib is prepared, it is possible to form a multilayer pattern having a uniform film thickness suitable for the quantum dot barrier ribs in a single development process. Thus, it can be advantageously used for a quantum dot display.

  • Patent number: 11465139
    Abstract: An anion exchange membrane is composed of a copolymer of 1,1-diphenylethylene and one or more styrene monomers, such as 4-tert-butylstyrene. The copolymer includes a backbone substituted with a plurality of ionic groups coupled to phenyl groups on the backbone via hydrocarbyl tethers between about 1 and about 7 carbons in length. High-temperature conditions enabled by these copolymers enhance conductivity performance, making them particularly suitable for use in anion exchange membranes in fuel cells, electrolyzers employing hydrogen, ion separations, etc. The properties of the membranes can be tuned via the degree of functionalization of the phenyl groups and selection of the functional groups, such as quaternary ammonium groups. Several processes can be used to incorporate the desired ionic functional groups into the polymers, such as chloromethylation, radical bromination, Friedel-Crafts acylation and alkylation, sulfonation followed by amination, or combinations thereof.

  • Patent number: 11433387
    Abstract: A system and method configured to restore ion exchange kinetic properties and purify resin is described. Degraded ion exchange kinetic properties of anion resin will eventually result in impurity slippage through resin charges. This system and method employs an acid catalyst in combination with sulfite cleaning solution to remove organic material and to protonate iron oxides for deconstruction and removal from anion resins. The cleaning solution, when applied via a cleaning vessel utilizing an eductor(s)/plenum and wedge-wire screen draw chamber, while controlling all phases of cleaning by electronic monitoring, yields complete restoration of ion exchange kinetics on usable resin. As such, the system and method provides a safe, effective, and vastly improved method for restoring anion resin kinetics and improving regeneration quality, for improved resin performance and minimizing resin replacement costs.

  • Patent number: 11420424
    Abstract: The price and performance of LED lighting have reached the point where LEDs are displacing more traditional lighting. Even though LED lifetimes are as high as 50,000 hours, they are still being designed as replaceable bulbs rather than being integrated as a permanent part of the lighting assembly. The invention provides for a means of economically producing laminated glass with integrated LED lighting designed to last the life of the vehicle. This is done by embedding the LED die into the plastic layer used to bond the glass layers of a laminate together, forming an embedded wire circuit from thin high tensile strength Tungsten wire to power the LEDs and by utilizing machine tool technology originally developed to produce integrated circuit assemblies such as RFID ID cards, tickets and passports.
