The present invention discloses one kind of epoxy-zinc soap compound as heat stabilizer for compounding polyvinyl chloride plastic. The heat stabilizer includes epoxy-zinc soap compound as main stabilizer, organic compound as co-stabilizer, and polyethylene as outer lubricant, and may also includes anionic laminated material, antioxidant, inner lubricant and other assistants. The stabilizer system may be used in compounding plasticized and unplasticized polyvinyl chloride plastic. The stabilizer is superior to available calcium-zinc stabilizer as far as the performance of polyvinyl chloride product.

The invention discloses a shower-type wet texturing equipment for solar silicon wafers, which comprises: a conveying assembly for forwardly conveying the silicon wafers, a spray assembly arranged above the conveying assembly, and a liquid supply assembly arranged below the conveying assembly. Silicon wafers are placed on the transport component at intervals, the transport component transports the silicon wafer forward, and the spray box sprays the liquid medicine downward; the liquid medicine flowing down from the transport component aggregates in the liquid receiving tank. The present invention also provides a method for wet texturing of solar silicon wafers by utilizing the shower type wet texturing equipment. In the shower mode of the present invention, the corrosion liquid is sprayed or dripped onto the silicon chip, and excess chemical liquid and reaction products flow to the liquid receiving tank, thereby ensuring uniform corrosion of the silicon chip.

The embodiment of the invention discloses a manufacturing process of a conductive ball, and belongs to the technical field of electronic elements. The process comprises the following steps that 1) physical derusting treatment is carried out on high-carbon steel shot blasting to obtain a high-carbon steel base material; 2) a nickel-iron alloy layer is electroplated on the surface of the high-carbonsteel base material; 3) a nickel alloy layer or a tin layer is electroplated on the surface of the nickel-iron alloy layer; and 4) the nickel-iron alloy layer is taken out, washed with water and alcohol, and drying is performed. According to the process, the physical rust removal and the nickel-iron plating solution process are adopted, so that the process is characterized in that the environmental pollution is reduced, the cost is saved, and the environment-friendly effect is achieved; an iron control agent can effectively inhibite ferrous ions to be oxidized into trivalent iron, the concentration of the ferrous ions in the plating solution is balanced, so that the nickel-iron co-deposition is realized without the influence of iron impurities in the continuous production process; nickel / tin plating machining is performed on the nickel-iron alloy layer, separation of iron in the subsequent use process can be effectively isolated, the oxidation resistance and the corrosion resistance of the conductive ball are improved, and the conductive performance of the conductive ball is improved.

The invention provides a method for improving the crystallization property of aluminum chloride mother liquor in a one-step acid-soluble method technology. The method comprises the following steps: (1), diluting the aluminum chloride mother liquor with water till the mass concentration of aluminum chloride is 360 to 380g / L, so as to obtain an aluminum chloride mother liquor diluent; (2), performing centrifugation on the aluminum chloride mother liquor diluent when the mass content of insoluble particles is great or equal to 10g / L; performing evaporation and concentration on a solution containing aluminum chloride, so as to obtain an evaporated liquor; performing evaporation and concentration on the aluminum chloride mother liquor when the mass content of the insoluble particles is smallerthan 10g / L, so as to obtain an evaporated liquor; (3), leaving the evaporated liquor to stand, then adjusting the acidity of the evaporated liquor to be greater than 0.01 mol / L; (4), performing centrifugation on the evaporated liquor, so as to obtain aluminum chloride crystals and reflux liquid. The method improves the crystallization property of the mother liquor, increases the particle sizes andpurity of the aluminum chloride crystals, and provides a good condition for the next calcination process.

The invention discloses a high-temperature soot water bath dedusting system, comprising: a cyclone dust collector, which includes a cylinder body, a cone body and an ash hopper arranged from top to bottom, the side wall of the cylinder body is provided with a soot inlet, a top A soot outlet is provided, and the outer wall of the cone is provided with a first water pipe; an acid removal tower, an alkali removal tower; a drying tower.
