Example Embodiment

[0024] Implementation example one

[0025] Weigh 71% original zinc oxide powder, 2% wetting agent nonylphenol ethoxylate (10EO), dispersant 4% phenethylphenol polyoxyethylene ether formaldehyde condensate, sodium lignosulfonate 1%, antifreeze Ethylene glycol 4%, water 17%, mix the above raw materials according to the general method, pour into a high-shear homogenizer for homogenization, then pour into a sand mill for sanding, and add thickener after sanding Xanthan gum 0.3% and antifoaming agent fatty acid polyoxyethylene ester 0.7%, fully stirred to obtain 70% zinc oxide suspension. The active ingredient zinc oxide is 70.2%, PH value is 7.9, suspension rate ≥93%, sieving (passing 75μm test sieve) ≥99.5%, mercury, arsenic, cadmium, lead, and chromium content ≤0.05%, remaining after dumping Substance ≤3%, residual characteristics after washing ≤0.05%, accelerated heat storage and accelerated cold storage stability are qualified. In practical applications, it is used to prevent and ...

[0026] Implementation example two

[0027] Weigh 71% of the original zinc oxide powder, 4% of the wetting agent phenethylphenol polyoxyethylene ether sodium sulfate, 4% of the dispersant nonylphenol ether phosphate, 4% of the antifreeze ethylene glycol, and 16.2% of water. The raw materials are mixed according to the general method, poured into a high-shear homogenizer for homogenization, and then poured into a sand mill for sanding. After sanding, add the thickener methyl cellulose 0.3% and the defoamer fatty acid polyoxygen Vinyl ester is 0.5%, and 70% zinc oxide suspension is obtained after full stirring. The effective ingredient of zinc oxide is 70.1%, PH value is 7.8, suspension rate ≥92%, sieving (passing 75μm test sieve) ≥99%, mercury, arsenic, cadmium, lead, chromium content of harmful substances ≤0.05%, remaining after dumping Substance ≤2%, residual characteristics after washing ≤0.05%, accelerated heat storage and accelerated cold storage stability are qualified. In pra...

Abstract

The invention relates to an agricultural microelement fertilizer, namely, a zinc oxide suspending agent. The zinc oxide suspending agent has the viscosity with high concentration and comprises,based on the mass percentage, 10 percent to 80 percent of zinc oxide original powder, 2 percent to 7 percent wetting agent, 3 percent to 10 percent of dispersant, 3 percent to 6 percent of antifreeze agent, 0.3 percent to 1.0 percent defoaming agent, 0.1 percent to 0.8 percent of thickener and 2.2 percent to 80.6 percent of water. After high shearing and uniform mixing are carried out, the fineness is between 100 nanometers to 1,000 nanometers by sand milling, and then the zinc oxide suspending agent is formed by using the thickener to adjust the viscosity. The zinc oxide suspending agent is prepared by adopting high-performance additive and advanced technology. The zinc oxide suspending agent is characterized by high active component contents, good dispersive property, steady heat storage performance and nano-sized fineness. In the application, the zinc oxide suspending agent has the advantages of fast zinc supplement, good effect, and small reagent dosage as well as being friendly to environment.

Description

technical field [0001] The invention relates to an agricultural trace element fertilizer, and relates to a zinc oxide suspending agent and components thereof. technical background [0002] With the production demand of high-quality vegetables and fruits, in the field of plant protection in my country, agricultural trace element fertilizers are more and more widely used. Zinc deficiency is a common phenomenon in fruit tree areas in my country. The symptoms of zinc deficiency are mainly chlorotic yellowing and whitening of plant leaves, chlorosis of leaves, yellowing between veins, macular mosaic, leaf shape is significantly smaller, and small leaf clusters often occur, which are called "small leaf disease", "leaf cluster disease" and so on. . Seriously affect the growth of vegetables and fruit trees, and affect the quality of products. [0003] At the present stage, zinc sulfate is mostly used for direct zinc supplementation to vegetables and fruit trees in my country's pl...
