Problems solved by technology

A large number of degreasing agents sold on the market have low alkalinity and large foam, which not only causes the problem of incomplete cleaning, but also consumes a lot of degreasing agents when used in steel mills, and additional defoaming agents need to be added, which greatly increases the on-site The labor intensity of workers increases, and the cleaning cost also increases

Abstract

The invention discloses a powder degreasing agent, a preparation method and a drying device thereof. According to the powder degreasing agent, the preparation method and the drying device thereof, sodium hydroxide is adopted, the saponification effect is high, and the powder degreasing agent has high cleaning capacity; 4A zeolite is added to avoid attachment of oil stains, so that the cleaning capacity is further improved; particularly, EO / PO block polymer is added, so that a good deoiling effect is achieved, and a foam inhibiting and defoaming effect is achieved; alcohol ether glucoside is used for compatibilizing the EO / PO block polymer; a main tank body and sub-tank bodies are integrally arranged, and the sodium hydroxide reacts when meeting water heat, so that heat energy utilization is improved, and energy is saved; a stirring device continuously stirs solution in the main tank body through a first stirring device and a third stirring device, a second stirring device is used for stirring the solution in the sub-tank bodies, and the solutions are more easily mixed through mutual stirring; the third stirring mechanism is formed by superposing stirring units with spiral structures, and is used for cutting and mixing the solution to realize stirring of the solution; and the whole solution is in an active state, and dissolution of the solution is further promoted.

Description

technical field [0001] The invention relates to a powder degreasing agent, its preparation method and drying device. Background technique [0002] In industrial production, it is necessary to use an emulsion composed of various oils to lubricate and cool the product. Therefore, this grease lubricant remains on the surface of the product after it is completed. Before the product is annealed, it must be chemically degreased and cooled. The method of electrolytic degreasing removes this layer of oil stain; to prevent this layer of oil stain from carbonizing on the surface of the steel plate during annealing, resulting in carburization and carbonaceous stains, which will affect the performance and quality of the product when it is coated or processed in the subsequent process . A large number of degreasing agents sold on the market have low alkalinity and large foam, which not only causes the problem of incomplete cleaning, but also consumes a lot of degreasing agents when used...
