Composite pellet soil additive and composite pellet soil production method

Abstract

The invention discloses a composite pellet soil additive and a composite pellet soil production method. The composite pellet soil additive comprises a formula A and a formula B. The formula A is prepared from 1 part of lauryl sodium sulfate, 1 part of sodium polyacrylate, 1 part of polyacrylamide and 3 parts of high-viscosity CMC. The formula B is prepared from 1 part of the lauryl sodium sulfate, 1 part of the sodium polyacrylate, 1 part of the polyacrylamide and 3 parts of polyvinyl alcohol. According to the composite pellet soil additive and the composite pellet soil production method, a prepared product is based on the principles of good biodegradability and low toxicity, the lauryl sodium sulfate is used as an emulsifier of medicines and cosmetics, a foaming agent of toothpaste, a fire extinguisher and a raw material of a detergent, and irritates respiratory tracts to cause respiratory tract allergy, and when the product is used, a user wears a dustproof mask, and the other components are non-toxic.

Description

technical field [0001] The invention relates to the field of additives, in particular to a compound pelletizing soil additive and a production method of the compound pelletizing soil. Background technique [0002] So far, the production and development of pellets has gone through three stages. The first stage is the stage of domestic pure magnetite with coarse particle size and high proportion of raw bentonite. The second stage is to artificially sodium bentonite, improve the activity of bentonite, and the ratio has decreased. The third stage is to improve the conditions of iron powder, the raw material of pellets, to add secondary selection and grinding, to increase the surface energy of iron powder particles, and to improve the hydrophilicity of particles. The production of pellets has developed by leaps and bounds. Since the financial crisis, steel The profit of the industry is sluggish, and many steel mills have stopped grinding and grinding to reduce costs. In addition...

The third stage is to improve the conditions of iron powder, the raw material of pellets, to add secondary selection and grinding, to increase the surface energy of iron powder particles, and to improve the hydrophilicity of particles. The production of pellets has developed by leaps and bounds. Since the financial crisis, steel The profit of the industry is sluggish, and many steel mills have stopped grinding and grinding to reduce costs. In addition to the current energy and environmental protection situation in the country, domestic iron ore resources are scarce, and foreign ore is added to varying degrees. The hydrophilicity of iron powder particles The general decline has brought great difficulties to the production of pellets. In the previous pellet annual meetings, experts have mentioned about increasing the viscosity of bentonite slurry to improve the cohesion between iron powder particles. At that time, domestic iron ore The resources are abundant, and the production of pellets is all magnetite. At that time, good results were received. According to the current decrease in the hydrophilicity of the iron powder particles used in the production of pellets, the cost of blindly increasing the viscosity is too high, with little effect, and it does not meet the requirements. At present, there are very few manufacturers using this method to produce pellets, which cannot be widely promoted. Therefore, this formula was invented.
