The invention relates to a technology employing a sheet material to achieve the laminating of a part, wherein an adhesive is applied to the surface of the laminated sheet material and / or the part in a mode of grid. Therefore, the adhesive is disposed between the sheet material and the part after the sheet material and the part are bonded. Moreover, a trench system is formed in a space between the used adhesive, and guarantees that air between the part and the sheet material can move uniformly. The invention also relates to a laminated molding part made through the above technology. The latticed adhesive is used between the part and the laminated sheet material guarantees the reduction or prevention of air contents when the part and the sheet material are laminated at the same time.

The invention relates to a method for preparing p-aminoanisole by catalytic hydrogenation of an industrial-scale device, which is to add raw materials to p-aminoanisole continuously or intermittently during each production cycle in an industrial-scale hydrogenation kettle. Nitroanisole, and real-time monitoring of the concentration of raw materials and impurities in the hydrogenation tank during the reaction to obtain p-aminoanisole with a purity of more than 99.5% and a yield of 100%. The p-aminoanisole product obtained by the present invention has a purity of more than 99.5%, and can be used and sold directly; it can also be further rectified to obtain a p-aminoanisole product with a purity of more than 99.9%, which can be used in special fields.

Particulate generation is often a problem with semiconductor component processing in a highly corrosive plasma environment. This problem is more serious when the above-mentioned plasma is reducing plasma. Experimental data shows that when forming a plasma-sprayed yttrium-containing ceramic (such as yttrium oxide, Y2O3-ZrO2 solid solution, YAG and YF3), when the average effective particle size range of the powder feed for spraying ceramics is between about 22 μm to about 0.1 μm provides a low porosity coating with a smooth and compact surface. These sprayed materials reduce particle generation in corrosive reducing plasma environments.

The invention discloses a metal cup for a tapered or arc-shaped diamond composite sheet. The metal cup consists of the following alloy components in percentage by weight: 15-20% of Ni, 5-10% of Cu, 1-5% of Al, 0.2-1% of Ti, 1-3% of Si, 0.5-1.5% of W and the balance of Co. Compared with the prior art, the metal cup has the advantages that: firstly, the metal cup replaces conventional powdered catalyst, purity and stability of the metal cup are higher than those of the powdered catalyst in aspect of a preparation process, and occurrence of a metal powder segregation condition is further avoided, so that performances of synthesized PDC are more uniform and stable, and the product yield also can be increased; secondly, the metal cup simultaneously realizes catalysis on diamond micro powder at the two sides or metal cups at the two sides simultaneously realize catalysis on diamond micro powder in the middle, so that each part of the tapered shape or the arc shape is catalyzed uniformly, stress distribution of tapered or arc-shaped PDC is also improved, and wear resistance, heat resistance and impact resistance of PDC are correspondingly improved.

The invention relates to a precipitation-enhanced AlCrFeNiV system high-entropy alloy and a preparation method thereof, belonging to the technical field of metal materials. The atomic weight ratio of each component in the high-entropy alloy is Al 0.30-0.60, Cr 0.20-0.89, Fe 0.60-1.20, Ni 1.50-3.50 and V 0.10-0.30, and is prepared by melting and forming process and deformation heat treatment process . The present invention obtains disordered FCC and ordered L1 by regulating the content of each element and optimizing the synthesis process. 2 The two-phase coherent amplitude-modulated structure and fine grains significantly improve the strength of high-entropy alloys.

The invention relates to a locking element (2), particularly a locking roller, for lockingbetween a vessel (4) of a kitchen appliance (3) and a cover (5), wherein the locking element (2) is provided with a base body (12) and a cover element (1) only partially covering the base body (1), the cover element (1) at least partially is provided with an edge region (7) of a folded edge facing the base body (12), and a the cover element (1) is arranged on the base body (12) by means of the edge region in a preloaded manner.

The invention relates to a deproteinised porcine blood extract, especially to a deproteinised porcine blood extract oral paste and its preparation technology, is a medicine for treating oral mucosa, gum and lip injury, inflammation or ulcer, artificial denture pressure sore and the like, and belongs to the technical field of biological pharmacy. The deproteinised porcine blood extract oral paste is made from the following raw materials of: by weight, 0.1-0.3 part of a deproteinised porcine blood extract powder, 15-20 parts of pectin, 5.5-10.5 parts of glycerin, 9.1-19.3 parts of dimethicone, 30-40 parts of white vaseline, 20-30 parts of liquid paraffin and 0.05-0.1 part of methyl nipagin ester. The medicine provided by the invention is used to treat oral mucosa, gum and lip injury, inflammation or ulcer, artificial denture pressure sore and the like, can replace a similar biological product with bovine blood as a source, has high drug safety, and has a more obvious curative effect than a deproteinized calf blood oral paste.

The invention discloses a rear trailing arm, which belongs to the technical field of automobile rear suspension. The rear trailing arm includes: an upper body, a lower body, a bushing, an upper swing arm connecting seat, a lower swing arm connecting seat, a brake mounting platform and a shock absorber mounting platform. By matching the upper body and the lower body formed by stamping a single-layer steel plate into a cavity, the overall strength of the rear trailing arm can be greatly improved, and the use of reinforcement plates can be reduced or avoided; and the first end of the cavity is stamped It can avoid the use of the transition arm by forming a suitable shape to directly connect with the bushing; thus, the rear trailing arm structure provided by the embodiment of the present invention can simplify the structure and processing procedures while ensuring the practical strength; and due to the stamping process The use of the invention and the simplification of the structure of the present invention greatly reduce the overall number of welding parts, thereby reducing the welding deformation of the rear trailing arm during the welding process, thereby improving the positioning accuracy of each joint of the rear trailing arm.
