A cart grip sanitary cover is provided having multiple layers each with a top face, a bottom face, and a periphery formed therebetween. The bottom face of each layer has adhesive formed thereon for adhering to a top face of an adjacent layer therebeneath. The layers are stacked with a bottommost layer being attachable to a grip of a cart. In use, a topmost layer of the sanitary cover is removable for exposing another layer therebeneath for providing a sanitary surface to be gripped by a user.

The invention discloses ZnO nanomaterial hybridized acrylic emulsion, polyacrylic copolymer emulsion water-based paint, a waterproof roll and a preparation method of the polyacrylic copolymer emulsionwater-based paint. The ZnO nanomaterial hybridized acrylic emulsion is prepared from the raw materials in parts by weight: 1-8 parts of acrylic acid, 12-18 parts of butyl acrylate, 20-25 parts of methyl methacrylate, 0.10-0.30 part of an initiator, 0.1-1 part of a dispersing agent, 1.5-3.0 parts of nano ZnO, 45-65 parts of water, 1-2 parts of an emulsifier, 0-10 parts of styrene, and 0-10 parts of acrylonitrile. As an n-type semiconductor compound, the nano ZnO can absorb energy of short-wave light radiation higher than the energy gap of the nano ZnO to generate electron transition and corresponding holes, and can transmit the energy to surrounding dielectrics, and thus the bonding performance of the waterproof roll in poured concrete is protected when the waterproof roll is exposed to the ultraviolet environment for a long time.

The invention relates to the field of circuit breakers, and particularly discloses a modular permanent-magnetic circuit breaker which comprises a shell. Three containing cavities are sequentially arranged in the shell from top to bottom, a vacuum pipe and a permanent-magnetic device are arranged in each containing cavity, a moving contact and a static contact are oppositely arranged inside each vacuum pipe, a rod portion of each moving contact extends out of one outer side of the corresponding vacuum pipe and is connected with the corresponding permanent-magnetic device through a connecting mechanism, a rod portion of each static contact extends out of the other outer side of the corresponding vacuum pipe and extends to one outer side of the shell to serve as an input end of the corresponding vacuum pipe, a current transformer is arranged on the rod portion, positioned in the corresponding containing cavity, of each moving contact, an electroconductive block is connected on the rod portion, extending out of the outer side of the corresponding vacuum pipe, of each moving contact and connected with an output end of the corresponding vacuum pipe through an electromagnetic band, and the output end of each vacuum pipe extends to the outer side of the shell on the same side with the input end of the corresponding vacuum pipe. The circuit breaker is modular and has the advantages of small size, simple structure, convenience in maintaining and replacing and easiness in trouble spot checking.

The invention provides a hepatobiliary surgical postoperative anti-infection dressing, and belongs to the technical field of medical supplies. The dressing comprises an outer layer, a protective layerand a dressing layer, wherein the outer layer is coated with medical adhesives, the protective layer is adhered with the outer layer, the dressing layer is arranged between the outer layer and the protective layer, the outer layer is made of cotton fibers or bamboo charcoal fibers, the protective layer is made of isolation paper, the dressing layer is prepared from gauze and medicinal preparations wrapped by the gauze, and bandages are arranged at two ends of the outer layer. The prepared dressing is applied to a wound, the isolation paper is stripped, the dressing layer is aligned to the wound and adhered when the dressing is used, the dressing is quite convenient and good in breathability, the medicinal preparations of the dressing layer can effectively inhibit bacteria, the infection rate of the postoperative wound is decreased, wound ache is relieved, wound healing is accelerated, skin cell metabolism is promoted, no obvious scar is present after treatment, and treatment effects are remarkable.

The invention provides a GaN-based LED and a method for manufacturing the GaN-based LED. The method for manufacturing the GaN-based LED comprises the following steps: (a) an n-type GaN, a multi-quantum well and a p-type GaN are successively formed on a substrate; (b) a transparent conductive layer is formed on the p-type GaN; (c) mesa etching is performed on one part of the transparent conductive layer, the p-type GaN and the multi-quantum well until one part of the n-type GaN is exposed; (d) an oxide protective layer is formed on the transparent conductive layer and the exposed part of the n-type GaN; (e) the oxide protective layer is etched on a position with no mesa etching so that one part of the transparent conductive layer is exposed, and the oxide protective layer is etched on the position with mesa etching so that one part of the n-type GaN is exposed; (g) and a p electrode and an n electrode are formed on a rough surface and the part that n-type GaN is exposed respectively. The probability and the degree of losing an electrode can be reduced by using the GaN-based LED.

The invention discloses a production process of a silver mirror, relates to the field of production and manufacturing of mirrors, and aims to solve the problems that the silver mirror is short in service life and low in reflectivity. The production process of the silver mirror is characterized by comprising the following steps: cleaning and polishing of glass; sensitization; hypersensitization; silver plating; passivation; preheating; primer spraying ; primer baking; spraying of an epoxy resin coating liquid; spraying of a finish paint; air cooling; surface pickling; surface cleaning; and airing. According to the production process of the silver mirror, the effects that the silver layer is long in durability, high in reflectivity and long in service life can be guaranteed.

The invention relates to a double-side-squeezing water squeezing device. The water squeezing device comprises a water squeezing frame with a squeezing opening; two sets of squeezing components are arranged in the squeezing opening and oppositely arranged in a front-back spaced mode; and during water squeezing, a mop head with the bottom face directly or indirectly bonded with foamed cotton is rotated to be aligned with the squeezing opening and passes through the squeezing opening, water squeezing is carried out on the front side surface and the rear side surface of the foamed cotton by moving oppositely arranged squeezing components along the length direction of the foamed cotton. The water squeezing device is characterized in that the squeezing components can be movably arranged in the squeezing frame relative to the squeezing frame; during water squeezing, the foamed cotton and/or the mop head firstly promote the squeezing components to move, and a squeezing channel is formed between the squeezing components after movement; and when the foamed cotton passes through the squeezing channel and is squeezed by the squeezing channel, and the squeezing force of the squeezing channel on the two sides of the outer end of the foamed cotton is larger than the squeezing force of the squeezing channel on the two sides of the inner end of the foamed cotton. According to the water squeezing device, in the cleaning and dry-squeezing operation process, the bonding face of the foamed cotton is not prone to being torn. The invention further relates to a cleaning tool and a self-squeezing foamed cotton mop.
