The invention discloses a compact-panel curved plate for architectural decorating and a manufacturing method thereof. The curved plate comprises a first slab, a second slab and a corner plate. The first slab and the second slab are arranged in a right-angle mode. The corner plate is arranged at the connecting position of the first slab and the second slab and forms a fillet-shaped structure at the connecting portion of the first slab and the second slab. The circular arc radius R of the corner plate is 8-20 mm. A rubber block is arranged in the corner plate. According to the manufacturing method, a through groove is formed in a planar compact panel, and after bending performing is carried out, epoxy resin is poured into the through groove, so that the curved plate with the stable structure is formed. The compact-panel curved plate is stable in structure and not prone to deformation, and the cambered surface radius can reach 8-20 mm; meanwhile, according to the manufacturing method, the circular arc radius R of the curved plate can be designed uniformly, the same die is used for manufacturing, the processing cost is saved, the curved plate can be produced in batches, and production efficiency is greatly improved.

The invention relates to the technical field of wind (water) power generation structures, in particular to a wind (water) power generator stressed in the forward direction. The wind (water) power generator comprises a generator spindle. The two ends of the spindle are provided with supporting plates which can rotate integrally with the two ends of the spindle. A plurality of blades are arranged between the two supporting plates. Sub spindles are arranged at the two ends of each blade. The supporting plates are provided with a plurality of matching holes which are in one-to-one correspondence with the blades. The sub spindles penetrate into the corresponding matching holes in the supporting plates. The states of the blades can be switched in the wind wheel rotating process, the blades can only achieve revolution on the rear half of the circumference (namely at the angle of 190-350 degrees) to generate thrust so that an acting area can be formed, the blades can only be rotated automatically on the front half of the circumference (namely at the angle of 10-170 degrees) so that a non-acting area can be formed, the spindle can be rotated under the resultant action to act, and the distance between the blades and the spindle and the sizes of the blades and the spindle can be changed so that the power and torque can be improved. The effective surface area of the blades is larger than that of a traditional impeller, practicability is greatly improved, manufacturing difficulty and production cost are lowered, and the range of the application field of the generator is widened.

The invention discloses a method for increasing the yellow tone of iron oxide yellow. After the iron oxide yellow directly obtained industrially is dispersed and the color is stabilized and enhanced, the iron oxide yellow is filtered, rinsed, dried and ground. The process of the method is as follows: the iron oxide yellow and water are added into a reaction bucket to form slurry with certain concentration, acid is then added to control the PH value of the slurry, stirring and reaction are carried out under a certain temperature for 2 hours, coating additive is then added, stirring and reaction are continued for 6 hours, and thereby the yellow tone Delta b can be enhanced. By technically processing the ordinary industrial iron oxide yellow and controlling certain slurry concentration, PH value, temperature, additive dosage and stirring time, the method can effectively enhance the yellow tone of the iron oxide yellow, so that the yellow degree of the ordinary iron oxide yellow directly produced industrially can be greatly increased by utilizing the simple method, consequently, the grade and quality of the product is effectively increased, and the application field range of the product is expanded.
