Anti-crystallization suspending agent capable of being rapidly uniform and stable

Abstract

The invention relates to the field of fertilizer auxiliary materials and provides an anti-crystallization suspending agent capable of being rapidly uniform and stable. The anti-crystallization suspending agent is used in high-concentration liquid water-soluble fertilizer. An effective component is prepared from the following raw materials in percentage by weight: 3.5 percent of sodium alginate, 1.5 percent of xanthan gum, 20 to 30 percent of glycerol and 65 to 75 percent of polyethylene glycol. The anti-crystallization suspending agent can rapidly absorb water to be expanded, and an original immersing and grinding process, which needs more than ten hours, is shortened; the anti-crystallization suspending agent can be instantly expanded to expected viscosity and the state of a product is uniform and stable. The suspending agent can realize the effects of increasing the viscosity of liquid to reach a suspending effect and also can realize an anti-crystallization effect in certain high-concentration systems. The raw materials adopted by the formula have no toxin and no harms and the formula has wide application. The utilization ratio of the product is 1 to 50; the adopted raw materials have no toxic side effect on crops.

Description

technical field [0001] The invention relates to the field of liquid fertilizer auxiliary materials, namely a fast, uniform and stable anti-crystallization suspending agent. Used in high-concentration liquid water-soluble fertilizers. Background technique [0002] In the prior art, there are many types of suspending agents commonly used in the market, the thickening effects are quite different, and the thermal stability and acid-base tolerance are also different. The suspension agent with good solubility has weak suspension effect, and the solubility agent with obvious suspension effect Unsatisfactory, glue clumping often occurs. [0003] The principle of the suspending agent is basically that the macromolecular compound absorbs the solvent and expands in the solvent, so as to achieve the effect of enhancing the viscosity of the liquid. However, because the contact mode of the suspending agent and the solvent is mostly mixed, the contact area cannot be guaranteed to be unifo...

[0002] In the prior art, there are many types of suspending agents commonly used in the market, the thickening effects are quite different, and the thermal stability and acid-base tolerance are also different. The suspension agent with good solubility has weak suspension effect, and the solubility agent with obvious suspension effect Unsatisfactory, often glued together

[0003] The principle of the suspending agent is basically that the macromolecular compound absorbs the solvent and expands in the solvent, so as to achieve the effect of enhancing the viscosity of the liquid. However, because the contact mode of the suspending agent and the solvent is mostly mixed, the contact area cannot be guaranteed to be uniform, and micelles are easy to form, and It takes a long time to soak to achieve the corresponding expansion degree. The short one takes several hours, and the long one even takes more than ten hours, which causes many adverse effects on the production process, prolongs the production cycle, and increases the production cost of the enterprise.
