5results about How to "Improve encapsulation" patented technology

This invention discloses an impact-resistant photovoltaic encapsulating film, its preparation method, and a photovoltaic module. The photovoltaic encapsulating film comprises multiple layers of unidirectional prepreg tape laminated together. The unidirectional prepreg tape is obtained by melt impregnation of thermoplastic resin and continuous fibers surface-treated with a coupling agent. The thermoplastic resin includes polyolefin elastomer (POE) and POE grafts. During the melt impregnation process, the continuous fibers surface-treated with the coupling agent and the POE grafts undergo a chemical reaction to achieve compatibility. This invention employs a pre-melt impregnation followed by crosslinking technique. The uncrosslinked POE resin has good fluidity and can be fully melt-impregnated with the continuous fibers. Electron beam irradiation post-treatment technology allows the impregnated base film to undergo a crosslinking reaction, resulting in a fiber-reinforced impact-resistant photovoltaic encapsulating film. The film prepared by this invention meets industry technical standards for UV resistance, aging resistance, and impact resistance, while also being low-cost and simple to manufacture, making it widely applicable in the field of lightweight flexible photovoltaic modules.

A pipe pillow for transporting and burying power conduits is disclosed. The pipe pillow has circular clamps for power conduits on the inner surfaces of one side pillow and the other side pillow. The outer surfaces of both side pillows have quarter-circle defect angles at the top and bottom, respectively. The upper and lower surfaces of both side pillows have dovetail grooves A and B, respectively. Two insert rods are used to pass through multiple dovetail grooves A and B on the upper and lower parts of both side pillows, respectively, and then two screws and two nuts are used to form a lock. This invention utilizes insert rods to pass through multiple dovetail grooves on the upper and lower parts of both side pillows to achieve modular splicing of rows of power conduits, facilitating fixing during transportation and concrete encapsulation, backfilling, or displacement, sliding, or adhesion during operation.

This invention provides a method for preparing and encapsulating solvent-resistant electronic paper microcups, belonging to the field of electronic paper display technology. Addressing the problems of uneven wall thickness and difficult demolding in existing electronic paper microcups, this invention aims to provide a solution. The method includes substrate pretreatment, microcup layer fabrication, template treatment, curing, demolding, oil phase filling, and sealing steps. Specifically, the template treatment uses perfluoroalkylchlorosilane for anti-sticking treatment, extending template life and enabling multiple uses; the microcup layer coating thickness is 20–100 μm to ensure uniform microcup wall thickness; the oil phase filling temperature is -25–40℃; and sealing uses a thin film with a thickness of 10–50 μm, which is effectively encapsulated through heat pressing and curing. This invention combines photopolymerization, nanoimprinting, and low-surface-area demolding technology to overcome the defects of uneven wall thickness and difficult demolding in existing technologies. The prepared microcup electronic paper exhibits good solvent resistance, high mechanical strength, and excellent encapsulation effect.

The invention discloses a nutritional composition for fatty liver and liver protection and a preparation method thereof, and relates to the technical field of nutritional health-care product preparation. The preparation method comprises the following steps: mixing fat-soluble components such as an elephantopus scaber alcohol extract with hydroxylated modified soybean phospholipid, and adding absolute ethyl alcohol to prepare a hydrophobic phase solution; deionized water is added into water-soluble components such as the walnut oligopeptide to prepare a hydrophilic phase solution; dropwise adding the hydrophobic phase solution into the hydrophilic phase solution, and performing high-shear stirring, intermittent ultrasonic emulsification, curing and spray drying to prepare a nano composite carrier; mixing with hippocampal peptide and ganoderan, and constructing a gradient release structure through double-layer hydroxypropyl methyl cellulose coating; and finally adding the remaining components and mixing to prepare the uniformly mixed material for tabletting. Multi-component synergistic lipid lowering, hepatocyte repairing and anti-oxidation and anti-inflammatory effects are adopted, the bioavailability is improved by matching with the nano-carrier and a gradient release technology, the liver protection and lipid lowering effects are remarkable, the storage stability is high, and the composition is suitable for long-term conditioning of people with fatty liver.
