This invention belongs to the field of material surface treatment technology, specifically relating to a wafer polishing slurry, its preparation method, and its application. The wafer polishing slurry comprises abrasives, oxidants, dispersants, surfactants, pH adjusters, and water. The components of the wafer polishing slurry work synergistically, shortening polishing time and improving polishing efficiency when applied to wafer polishing. Furthermore, it significantly improves the surface quality of the polished wafer, markedly reducing scratches and defects, and lowering surface roughness to below 0.15 nm, thus meeting the surface quality requirements of fields such as power electronics and radio frequency devices.

This utility model belongs to the technical field of chemical storage tanks, specifically a chemical storage tank for preventing sedimentation. It includes a tank shell, with an agitation mechanism at the center of the shell for dispersing chemical sediment. At the lower end of the shell is a gas agitation mechanism that utilizes inert gas microbubbles to create disturbance. When the utility model is running, the motor starts, driving the main gear to rotate via the output shaft. The coupling rotates with the output shaft, driving the rotating disk. The main gear meshes with three driven gears, driving them to rotate along the outer circumference. Simultaneously, the driven gears drive the lower driven gears to rotate, thus driving the active gear. The rotating column and connecting rod cause the agitator and agitator blades to perform three-dimensional motion, rotating on their own axis while revolving around the sun. This structure achieves powerful agitation of the materials inside the utility model, breaking up agglomerated particles and eliminating dead zones in the agitation process.

This invention relates to the field of biofertilizer technology, specifically disclosing a microalgae biofertilizer with soil remediation function and its preparation method. The preparation method includes: domesticating and culturing *Scenedesmus obliquus* liquid, *Cyanobacterium cyanobacteria* liquid, and *Monoflagellates* liquid with γ-aminobutyric acid-induced activation solution, and co-culturing them with *Bacillus polymyxa* and *Bacillus megaterium* to obtain a bioslurry; encapsulating the bioslurry with sodium alginate-carboxymethyl chitosan to obtain bioactive microspheres; impregnating corn straw with magnesium-iron salt precursors and pyrolyzing it under nitrogen to obtain modified biochar loaded with magnesium oxide and iron oxide, and compounding it with potassium humate to obtain a biochar suspension; and mixing the bioactive microspheres, biochar suspension, xanthan gum, zeolite, ammonium polyphosphate, potassium nitrate, zinc sulfate, potassium silicate, and deionized water evenly to obtain the microalgae biofertilizer with soil remediation function.

This invention relates to a device and method for testing the airtightness of airbags in air-shield dams, belonging to the field of airtightness testing technology. It includes a main body, an airbag disposed between clamping plates, an injection pipe on one side of the main body, an air outlet on one side of the airbag, a locking assembly between the injection pipe and the air outlet, a stirring assembly inside the injection pipe, and a clamping assembly on one side of the lead screw. This invention achieves automatic opening of the air passage during docking and bidirectional automatic sealing during separation through plug-in self-sealing, preventing gas leakage and blocking impurities such as water vapor and dust from entering the air passage and the airbag interior. Combined with a mechanical locking structure using inclined plane transmission, it can resist the impact of inflation pressure and the tensile force generated by airbag deformation, ensuring that the interface remains secure and does not detach throughout the process. This eliminates external leakage not caused by the airbag itself, ensuring that the test results accurately reflect the airbag's sealing state and significantly reducing the probability of misjudgment.

The utility model discloses a corn steep liquor supplementing tank which comprises a tank body, the tank body comprises a tank top and a tank body, a machine base is arranged in the center of the tank top, a stirring driving device is installed on the machine base, the stirring driving device is connected with a stirring shaft extending into the tank body through a coupler, and a first stirrer and a second stirrer are arranged in the middle and at the lower end of the stirring shaft respectively. A feeding hole is formed in one side of the tank top, a hoisting device is annularly arranged on the periphery of the tank top, a flange plate and a sealing gasket are arranged on the butt joint surface of the tank body and the tank top, a jacket is arranged outside the tank body, a steam inlet is formed in the top side of the jacket, a condensed water outlet is formed in the bottom of the jacket, and a discharging hole is formed in the bottom of the tank body. The corn steep liquor supplementing tank can effectively reduce scaling and equipment cleaning frequency, has the advantages of being convenient to clean, good in cleaning effect and the like, and can effectively guarantee normal operation of equipment and maintain production efficiency and product quality.
