The cleaning component includes a fixed plate located at the upper end of the seat structure and parallel to its upper surface; a cleaning block disposed on the fixed plate; and two sliding plates disposed at both ends of the fixed plate and slidably connected to the two support components respectively. This utility model, while ensuring the supporting effect of the seat, allows the cleaning component to slide smoothly on the seat, making the outdoor metal chair compatible with support, cleaning effect, and aesthetics.

This invention belongs to the field of grinding disc manufacturing technology, specifically relating to a diamond positioning and implanted grinding disc and its manufacturing method. The grinding disc substrate undergoes a series of processes including degreasing and activation treatments, followed by basic nickel plating to form a base nickel plating layer. Then, using photolithography, a photosensitive dry film pattern with pre-drilled micro-holes is created on the surface of the nickel plating layer. Adhesive is then applied to fill the micro-holes, and diamond abrasive grains are implanted, ensuring the sharp corners remain upwards for initial fixation. Finally, the photosensitive dry film is removed, and a thicker nickel plating reinforcement treatment is performed, ensuring the diamond abrasive grains are firmly encapsulated by the nickel plating layer. This method utilizes photolithography to achieve precise positioning and uniform distribution of the diamond abrasive grains on the substrate surface, and through process control, maintains the abrasive grains in a favorable cutting posture with their sharp corners upwards, significantly enhancing the grain holding strength and effectively preventing loosening, collapse, or detachment. The resulting grinding disc exhibits superior cutting efficiency and stability.

The invention relates to an LSPC foamed sheet and a preparation method thereof, and belongs to the technical field of foamed materials. In order to solve the problems that an existing foamed stone-plastic plate is uneven in foam hole, insufficient in strength and prone to local collapse, a novel foam regulator is introduced into a PVC-based foaming system. According to the regulator, through hydrosilylation, ring opening and silane coupling reaction, a polysiloxane-alkyl ester functional structure is grafted on the surface of nano silicon dioxide, bubbles are induced to be uniformly nucleated by utilizing low surface tension of the functional structure, and bubbles are inhibited to be aggregated through an interface adhesion energy barrier, so that a uniform and fine closed-pore structure is formed. The density of the obtained LSPC board is reduced, and the LSPC board has excellent mechanical strength and high-temperature collapse resistance and is suitable for bearing, floor heating and other scenes.

This utility model discloses an electrolyte tank with an anti-precipitation and anti-turbulence structure, relating to the field of electrolyte tank technology. It includes a shell, a rotor pump on one side of the shell, a pipe fixedly connected to the input end of the rotor pump, the pipe penetrating the side wall of the shell and extending into the shell, a sealing plate slidably inserted into the shell, a power chamber on one side of the shell, and a drive assembly inside the power chamber, the drive assembly being connected to one end of the sealing plate. This utility model isolates the shell into two areas through the sealing plate. This design ensures that the operation of collecting precipitated impurities is independent of the area containing the normal electrolyte, avoiding interference with the normal electrolyte during precipitation collection. For example, it prevents precipitated impurities from being stirred and then mixed back into the normal electrolyte, ensuring the purity and quality of the normal electrolyte and facilitating the stable operation of the electrolysis process.

This application provides a collagen peptide for increasing bone density and a method for preparing the same. The method includes the following steps: S1: dispersing bone gelatin in water to obtain a bone gelatin solution; S2: adding 0.1-1 mol / L acidic pH adjuster to the bone gelatin solution at a rate of 1-10 mL / min until the turbidity of the system increases by 10%-20% compared to the initial bone gelatin solution, then stopping the addition, allowing it to stand for 10-30 min, and filtering to obtain a bone gelatin supernatant; S3: adding an endopeptide to the bone gelatin supernatant to obtain an enzymatic hydrolysate; S4: post-processing and drying the enzymatic hydrolysate to obtain collagen peptides. This method can increase the mass ratio of low molecular weight peptides in the obtained collagen peptides, resulting in a composition of collagen peptides more suitable for bone metabolism and utilization to increase bone density.
