This invention discloses a time-release, slow-release, blood sugar-controlled compound cereal nutritional powder, its preparation method, and its applications, belonging to the field of functional cereal food technology. It comprises: 10-15 parts of fast-phase particles, 35-45 parts of slow-phase gradient-degrading gel microspheres, and 30-40 parts of complementary-phase particles; each is an independent particle form, and after oral administration, they act sequentially during gastrointestinal digestion: the fast-phase particles first contact the digestive juices, releasing a small amount of rapidly energy-providing dextrin within 5-10 minutes and stimulating the satiety center; the slow-phase gradient-degrading gel microspheres then gradually degrade, continuously releasing carbohydrates 1-3 hours after a meal; the complementary-phase particles begin to degrade 3 hours after a meal, supplementing energy supply in the late postprandial period; thus, they synergistically achieve stable blood sugar control throughout the postprandial period. This invention can match the insulin secretion window to control blood sugar, precisely delaying energy release to avoid late postprandial hypoglycemia, and achieving stable blood sugar control throughout the postprandial period.

The utility model discloses a high-speed wire rod mill pre-finish rolling inlet sliding guide and guard set which comprises an inlet sliding guide and guard set body, an inner cavity is formed in the inlet sliding guide and guard set body, connecting pieces are welded to the front side and the rear side of the upper end of the inlet sliding guide and guard set body, and bolts are installed on the connecting pieces. The left side of the bottom end of the inlet sliding guide set body is fixed to a rolling mill through fixing bolts, and the front set and the rear set of fixing bolts are arranged. The front side and the rear side of the upper end of the inlet sliding guide set body are fixed through the bolts, and then the fixing bolts at the bottom end of the left side of the inlet sliding guide set body are matched for fixing, so that the left inlet sliding semi-guide, the right inlet sliding semi-guide and the guide base form a firm fastening relation, and the stability of the production process is guaranteed; the limiting device is mounted between the lower end of the inlet sliding guide group body and the guide base, so that the inlet sliding guide group body can be mounted more firmly, and the stability is higher.

This invention discloses a process and method for preparing battery-grade manganese tetroxide using a manganese sulfate solution, belonging to the field of new energy battery materials and hydrometallurgical technology. The process uses a manganese sulfate solution as the manganese source and achieves one-step preparation of battery-grade manganese tetroxide through raw material preparation and process steps. The raw materials include a manganese sulfate solution (manganese concentration 40-130 g / L, low impurity content), a precipitant (10-35 wt% sodium hydroxide or 5-20 wt% ammonia), an oxidant (3-15 wt% hydrogen peroxide, air, or oxygen), a modifier (0-10 g / L, such as sodium tartrate, EDTA, etc.), and ammonium salts (0-30 g / L, such as ammonium sulfate, ammonium chloride, etc.). The process steps include: heating the reaction solution to 40-90℃, adjusting the pH to 7-10, continuously adding manganese sulfate solution, precipitant, and oxidant, controlling the pH change within ±0.3, reacting for 10-100 hours, stopping the manganese solution feed, maintaining the pH for 0.5 hours, and aging for 0.5-6 hours. After filtration, washing (conductivity ≤100μS / cm), and drying, the product is obtained. Wastewater is treated with a manganese precipitant (such as sodium carbonate) to recover manganese carbonate, and the solution is concentrated and crystallized to obtain sulfate byproducts. This invention features a short process flow, low cost, high product purity (manganese content ≥70%), controllable particle size, and high resource utilization, making it suitable for the production of cathode materials such as lithium manganese oxide and lithium manganese iron phosphate.
