The invention belongs to the technical field of photocurable additive manufacturing, and specifically discloses a bioceramic slurry used for high-performance DLP printing and a preparation method thereof. The bioceramic slurry comprises bioceramic powder, premixed solution, dispersant and release agent, wherein the mass ratio of the bioceramic powder to the premixed solution is 1: 7-7: 3, and thepremixed solution comprises polyethylene glycol and photocurable resin with a mass ratio of 3: 20-2: 5. The preparation method comprises the following steps of: uniformly mixing photocurable resin andpolyethylene glycol, adding dispersant into premixed solution for ultrasonic mixing uniformly, adding bioceramic powder into the mixed solution, and stirring uniformly, then adding release agent intothe bioceramic slurry initial body, and stirring uniformly, so as to prepare the bioceramic slurry. The bioceramic slurry prepared by the invention can facilitate the lifting of the green body and reduce the internal stress of resin curing in the forming process, reduce degreasing cracking, and improve the success rate in the printing and degreasing processes.

The invention relates to a high-strength anti-pinch garment which is characterized by comprising a garment body, a zipper and a pair of positioning strips.The zipper is mounted in the middle of the garment body, the pair of positioning strips is fixed onto the garment body and is positioned on two sides of the top of the zipper, and detaching zippers are arranged at sleeves of the garment body.The high-strength anti-pinch garment has the advantages that the high-strength anti-pinch garment with an inflation neck protector is provided with the pair of positioning strips, the weight of the high-strength anti-pinch garment can be increased, accordingly, the zipper can be smoothly zipped, and potential safety hazards of physical injury due to the fact that the neck of a wearer is easy to pinch when the wearer zips the zipper by the single hand can be reduced.

The invention provides a ceramic bowl achieving negative pressure fixing using principal of expansion caused by heat and contraction caused by cold of air, and relates to the field of ceramic bowls. The ceramic bowl comprises a bowl body and a tray, and the side of the bowl body is fixedly connected with a fixing block; through the arranged bowl body, first heat conductive metal, second heat conductive metal, third heat conductive metal, heat conductive holes, clamping grooves and an air bag, the heat of a cooked dish when the cooked dish is put into the bowl body can only be transmitted fromthe first heat conductive metal of the bottom of the bowl body to the second heat conductive metal to allow the second heat conductive metal to transmit heat to the third conductive metal, the heat istransmitted to the clamping grooves from the heat conductive holes by the third heat conductive metal, the ceramic bowl is firmly fixed, and the problem that most of existing ceramic bowls are hard to be hold horizontally due to the fact that too many dishes are loaded is solved.
