6results about How to "Good separation" patented technology

The application provides a light emitting diode and a manufacturing method thereof. An insertion layer is arranged between a metal reflection layer and a dielectric film layer. The adhesion between the material of the insertion layer and the material of the dielectric film layer is greater than the adhesion between the material of the metal reflection layer and the material of the dielectric film layer. The adhesion between the metal reflection layer and the dielectric film layer is improved through the insertion layer. The separation between the metal reflection layer and the dielectric film layer is improved. The reliability of the light emitting diode is improved.

The present invention relates to a road surface repair and cleaning device, belonging to the technical field of road surface maintenance. The device is mainly composed of an impact unit group, a cleaning unit group and a collection unit group. The impact unit group breaks the road surface through a swing frame and an impact assembly, and a driving mechanism I drives the swing frame to swing through a crank-connecting rod mechanism. The cleaning unit group uses the cleaning assembly on the fixed frame to remove road debris, and its input end is connected to the driving mechanism I to achieve power sharing. The collection unit group collects the cleaned debris into a collection box through the collection bin and the conveying assembly on the chassis. The chassis and the support frame are assembled through a connecting frame, and the moving wheels facilitate the movement of the equipment. In addition, a positioning assembly is also provided at the front end of the chassis for supporting the fixed swing frame. The present invention realizes the cleaning operation before road surface repair through an integrated design, reduces the operating intensity of construction personnel, improves work efficiency, and provides an efficient and convenient solution for road surface maintenance.

The present application is a kind of low-temperature forming polyurethane resin and its leather product, the polyurethane resin, comprising the reaction product of polyisocyanate, polyol mixture and chain extender;Wherein, the polyol mixture contains polyester polyol, the polyester polyol includes mass ratio of 4:1~1:2 linear aliphatic polyester polyol and branched aliphatic polyester polyol. The low-temperature forming polyurethane resin prepared leather product can significantly improve the degree of phase separation of polyurethane internal soft and hard segment micro area, the resin as synthetic leather surface layer material, with polyurethane shoe sole can have good bonding strength at lower injection temperature, not easy to delaminate, and good heat aging resistance, low temperature resistance.

The invention discloses a lightweight high-strength composite material, and belongs to the technical field of composite boards for electronic products, the composite material is formed by laminating and thermocuring at least one layer of prepreg, and the prepreg is prepared by impregnating a reinforcing material with a resin sizing material and then baking, the resin sizing material is prepared from raw materials in parts by weight as follows: 100 parts of epoxy resin, 60 parts of polypyrrole modified glass beads, 8-15 parts of a toughening component, 25-30 parts of a curing agent, 0.1-0.5 parts of an accelerant, 2-3 parts of a flame retardant and 50-60 parts of a solvent. The polypyrrole modified glass beads are added into a resin sizing material, a heat conduction network is formed in an epoxy resin matrix, the density of the composite material is reduced, meanwhile, the heat dissipation performance of the composite material is improved, and the safety of the composite material in the use process of electronic products is ensured.

The invention belongs to the technical field of medicine quality control, and particularly relates to a method for detecting related substances of a benidipine hydrochloride intermediate I. The invention finds that an impurity R, namely 6-methyl-2, 4-bis (3-nitrophenyl)-1, 2, 3, 4-tetrahydropyrimidine-5-carboxylic acid methyl ester, exists in a benidipine hydrochloride intermediate I for the first time. Furthermore, the invention provides a method for detecting the quality of the benidipine hydrochloride intermediate I through high performance liquid chromatography, and the chromatographic conditions are as follows: octadecylsilane chemically bonded silica is used as a filler, and a phosphate solution with the pH value of 5.5-7.5 and acetonitrile are proportioned to serve as a mobile phase A or a mobile phase B. The invention further provides a method for detecting the quality of the benidipine hydrochloride intermediate I through high performance liquid chromatography. Within the range of the detection method provided by the invention, various impurities in the benidipine hydrochloride intermediate I can be accurately detected through the synergistic effect of detection conditions, the high-efficiency control of the medicine quality can be realized, the effectiveness and safety of the medicine are improved, and the application prospect is very good.
