The invention relates to the technical field of inorganic synthesis, and discloses a preparation method of a trivalent rhodium acetate trimer, comprising the following steps: (1) mixing rhodium powder and potassium chloride, and then introducing chlorine gas for reaction; (2) mixing The product obtained in step (1) is dissolved in water, filtered, potassium hydroxide is added to the filtrate for reaction, and rhodium hydroxide is obtained after filtering and washing; (3) water, nitric acid and glacial acetic acid are added to rhodium hydroxide Carry out the reaction, evaporate the solution to dryness after the reaction is completed, use glacial acetic acid to remove the nitrate, and then use water to remove the acid to obtain trivalent rhodium acetate trimer. The invention adopts nitric acid and glacial acetic acid to dissolve rhodium hydroxide, and then uses glacial acetic acid to catch up with the nitric acid, so that the reaction speed can be obviously accelerated, thereby increasing the yield of trivalent rhodium acetate trimer.

An intelligent sandstone aggregate production line, which relates to the technical field of sandstone aggregate production. The intelligent sandstone aggregate production line comprises an intelligent jaw type crusher, an intelligent impact type crusher, a vibrating screen, a vibrating feeder, a material bin, a hopper, a belt conveyor, a control-related network type integrated electric control system, a distributed control system, and an intelligent internet-of-things monitoring cloud platform. A variety of sensors are additionally mounted on the basis of an original crushing screening production line. Sensor information is transmitted to the distributed control system through the network type integrated electric control system, so that automatic regulation and control on the production process is achieved, and then, the sensor information is transmitted to the intelligent internet-of-things monitoring cloud platform; and by means of cloud computation, production data storage and safety are managed in a unified manner on the basis of classification and combing. The intelligent sandstone aggregate production line has a fault early-warning function and a real-time alarm function, and quickly increases the response speed; the internet-of-things intelligent control and remote monitoring are introduced, the production process is automatically regulated and control, operation is performed with optimal load, the yield is increased, and the downtime maintenance is reduced.

An image forming apparatus includes: a first conveying member that nips and conveys a sheet; a guide member rotatable between a first guiding position where the guide member guides a sheet that is conveyed by the first conveying member toward a first direction and a second guiding position where the guide member guides the sheet toward a second direction that is different from the first direction; a second conveying member that conveys a sheet that has been guided toward the first direction; a third conveying member that conveys a sheet that has been guided toward the second direction; a driver that drives the guide member; an acquiring portion configured to acquiring a basis weight of a sheet; and a controller that controls the driver such as to change torque for driving the guide member based on a basis weight of a sheet acquired by the acquiring portion.
