The invention discloses a process for processing an aluminum mesh watch strap, which solves the problems of the heavy material of the stainless steel watch strap and the limited color of the traditional electroplating process. Its technical features are as follows: S1, prepare the watch strap Required raw materials, the raw materials are washed, and the number of times of washing is 3-5 times, and then the wire rod after washing is put into a vacuum drying box for drying, and the drying time is 30-40 minutes, and it is standby; after the aluminum material in the present invention is oxidized, the metal The strength is harder than stainless steel, and it is not easy to scratch. It solves the problem of the unsatisfactory electrical conductivity of the aluminum mesh structure woven by traditional technology, and the non-conductive situation of the mesh strap. There is no mesh layer on the mesh surface that is electrified and oxidized. The phenomenon of yellowing and blackening, and the radiation amount of the nickel metal of the watch strap made by the embodiment of the present invention is zero, which will not cause harm to the user's body.

The invention provides a method for processing semi-dry brewed rice noodles, which relates to the technical field of food processing. The method for processing semi-dry brewed rice noodles of the present invention comprises the following steps: (1) preparation of raw materials, (2) fermentation, ( 3) Refining, (4) Blending, (5) Enzymolysis, (6) Initial steaming, (7) Extruding, (8) Optimizing, (9) Re-steaming, (10) Cooling, (11) Drying; The invented semi-dry brewing rice noodles process the semi-dry convenient brewing rice noodles with moisture content controlled at 14-16% by adjusting the ratio of materials, secondary fermentation combined with amylase optimization treatment and finished product moisture control.

The invention relates to a municipal pointing device, which comprises two sucking devices, two connecting plates, a sliding plate, a handle and a jointing device, two connecting plates are connected between the two sucking devices, two The middle part of the sucking device is provided with a sliding plate, the middle part of the sliding plate is provided with a handle, and the lower side of the front end of the handle is provided with a jointing device. The present invention can solve the problem that the existing pointing tools have a single structure. When pointing, the direction and depth of the pointing tools need to be controlled by hand, and the attention of personnel needs to be kept concentrated for a long time. When pointing, distraction is very easy to cause The movement direction of the tool deviates, which leads to the fact that there is no pointing treatment for the gap at this place. Long-term operation often accelerates the fatigue of the personnel, and the structure of the existing pointing tools is fixed, and the effect after pointing is single, which needs to be done. When dealing with gaps with different effects, it is often necessary to carry tools with multiple structures.

The invention discloses a polyurethane elastomer polishing material and a preparation method therefor and belongs to the technical field of functional polymer materials and preparation methods therefor. The polyurethane elastomer polishing material is mainly used for solving the technical problems of the existing polyurethane polishing materials that the quality is poor, the preparation process is hard to control, the production cost is high and the environment is easily polluted. According to the polyurethane elastomer polishing material and the preparation method therefor, the polyurethane elastomer polishing material is prepared by a quasi-prepolymerization method, and the polishing material is modified through adding a small amount of hydroxyl-terminated polyether polyol grafted styrene copolymer into the polishing material. The polyurethane elastomer polishing material consists of two ingredients, i.e., an ingredient A and an ingredient B, is prepared through the steps of adding the ingredient A and the ingredient B into a mixing reactor, carrying out rapid stirring for 10 to 15 seconds, then, rapidly pouring the mixture into a cylindrical metallic steel mold for foaming, covering a top cover of the mold in place when the material rises to a position of the two-thirds of the height of the mold through foaming, firmly fixing the top cover, putting the mold in a baking oven of 100 DEG C, carrying out vulcanization molding for 8 hours, and carrying out cooling and can be sliced on a lathe with a lathe tool according to thickness requirements. The polyurethane elastomer polishing material has the advantages that the quality is good, the preparation process is easy to control, the production cost is low and the environment is not polluted.
