The invention relates to a woodenware paint and a preparation method, and especially relates to an outdoor aqueous woodenware matte clean finishing coat and its preparation method, which belong to the paint field for building decoration. The provided outdoor aqueous woodenware matte clean finishing coat comprises the following raw materials by weight: 10-14.6 parts of water, 0.1-0.15 parts of aqueous multifunctional auxiliary agent, 1-5 parts of aqueous flatting silica, 73-78 parts of aqueous pure acrylic acid emulsion, 4-5 parts of film forming auxiliary agent and 0.3-0.5 parts of aqueous levelling agent. The prepared outdoor aqueous woodenware matte clean finishing coat has excellent weatherability, can protect base materials from being destroyed; the usage is simple, the construction tolerance is wide and the application scope is wide.

The invention relates to waterproof paint for metal. The waterproof paint is prepared by polyurethane resin, epoxidized soybean oil, a coupling agent, an antifoaming agent, a leveling agent, hard barium, zinc oxide, calcium silicate, nanoscale titanium oxide, nanoscale activated carbon, filler and a solvent. Experiments show that the waterproof paint is better in waterproof ability as compared with a comparison product. In addition, the waterproof paint has the advantages that the waterproof paint is extremely long in service life, a paint film can be prevented from falling off in 2-3 years under normal conditions, paint film maintaining cost is lowered greatly, and the waterproof paint is worthy of popularization and application.

The invention provides a nursing bottle with a biased nipple, and belongs to the industry of infant and children supplies. The nursing bottle comprises a bottle body, a bottle cap, a nipple with a one-way vent valve and a dustproof cover, wherein an outer thread is formed in an opening end of the bottle body; an inner thread and a center hole are formed in the bottle cap; the nipple is arranged in the center hole; the outer thread of the bottle body is connected with the inner thread of the bottle cap to form a sealed space; a feeding opening and at least one one-way valve which protrudes inwards are arranged on the nipple; an air intake opening is formed in the top part or the side surface of the one-way valve; an annular groove which is used for relieving deformation of the nipple and surrounds the one-way valve is arranged at the periphery of the root part of the connected part of the inside of the nipple and a large arc surface; an annular body which protrudes upwards is arranged on a seal edge of the lower part of the nipple for preventing the nipple from falling off; the annular groove which protrudes out of the annular body downwards and sinks into the bottle cap upwards is arranged at the lower part of the edge of the center hole of the bottle cap; a bulge body aligned with the dustproof cover is arranged on the edge of the outer surface of the bottle cap; and a leak-proof device which is in contact with the feeding opening of the nipple and is used for preventing a liquid in the bottle body from flowing outside is arranged in the top part of the dustproof cover; and a groove aligned with the feeding opening of the nipple after the feeding opening of the nipple and the bottle cap are clamped is arranged at the inner side of the edge.

A surface residual electrolyte removal device for a waste lithium titanate negative electrode sheet is disclosed, the device includes a bracket, a material receiving box is fixedly installed at the upper end of the bracket, a material discharge hopper is arranged at the low end of the material receiving box, a rack is fixedly installed on the inner wall of the material receiving box, a plurality of push rod motors are vertically fixedly installed on the rack, the upper ends of the push rod motors are hinged with mounting strips, the upper end of the mounting strips is fixedly installed with abottom plate, a rubber sealing strip which is closely slidably connected with the inner wall of the receiving box is pasted on the outer wall of the bottom plate, and a mesh cylinder is arranged on the upper end of the bottom plate. The beneficial effects are as follows: the urface residual electrolyte removal device for the waste lithium titanate negative electrode sheet can thoroughly remove theelectrolyte and impurities on the surface of the waste lithium titanate negative electrode sheet, ensures that the lithium titanate powder on the waste lithium titanate negative electrode sheet can be completely detached from the aluminum foil without residue, effectively avoids the reduction of the recovery efficiency of the waste lithium titanate negative electrode sheet, and has good practicability.

The present invention relates to the technical field of sorting robots, in particular to a deep learning-based object recognition pre-sorting robot and its use method, including a mechanical part of the robot and a recognition part, the bottom of the mechanical part of the robot is fixedly connected to a base, and the The left end of the base is fixedly connected with a controller, the other end of the mechanical part of the robot is fixedly connected with a transition plate, the bottom end of the transition plate is fixedly connected with a side plate, and the inner side of the side plate is fixedly connected with an electric telescopic rod. The other end of the electric telescopic rod is fixedly connected with a splint. In the present invention, through the fixed block, the first motor, the gear, the gear ring, the limit frame, the telescopic rod, the first spring, the support plate and the ball, when passing through the splint When the item is picked up, the bottom of the item is supported by the gear ring with the support plate to ensure that when the item falls off before the splint, it will not fall to the ground under the action of the support plate, thereby improving the overall stability and security.
