Description
Technical Field
The invention relates to a method for rapidly judging the wrapping uniformity of a fully water-soluble liquid anti-caking agent on a fertilizer, belonging to the technical field of fertilizer anti-caking agent detection methods.
Background
With the increasing new demands of crops and the increasing environmental protection, the fertilizer market is constantly changed, at present, fertilizer enterprises produce water-soluble fertilizers increasingly, the added fertilizer anti-caking agents are mainly water-soluble liquid anti-caking agents, and the liquid anti-caking agents are high in water solubility, clear, transparent and colorless, can not be used for visually judging the uniformity and uniformity of the wrapped fertilizers after being sprayed on the surfaces of the fertilizers and can not give early warning and precaution to the caking risk of the fertilizers after being stored.
In addition, since moisture contained in the fertilizer remains in the fertilizer in the form of a saturated solution and continuously permeates between fertilizer particles, it is crystallized out when the ambient temperature and humidity are changed. With the repetition of the "dissolution-crystallization" process, salt bridges are formed between the fertilizer granules, eventually leading to caking of the fertilizer. Therefore, whether the anti-caking agent is uniformly wrapped on the surface of the fertilizer is very important, and the anti-caking agent is also a precondition for ensuring the anti-caking effect. The anti-caking agent can effectively prevent salt bridges from being generated between fertilizer particles after the surface of the fertilizer is uniformly coated, and plays a positive anti-caking role.
The person skilled in the art of the patent CN205246510U proposes: the experimental device and the experimental method are used for evaluating the anti-caking effect of the anti-caking agent added fertilizer, the anti-caking effect of the anti-caking agent added fertilizer can be evaluated by using the experimental device, the using environment of the fertilizer needs to be simulated after the anti-caking agent added fertilizer enters the experimental device, the fertilizer is stored in the constant-temperature and constant-humidity box for a certain time under the condition of constant pressure, and the fertilizer is taken out to judge the quality of the anti-caking effect after the anti-caking agent is added by testing crushing pressure.
Some water-soluble fertilizers in the market generally take urea, urea-based and nitro-compound fertilizers as main materials, the fertilizers are easier to agglomerate than conventional fertilizers, the corresponding anti-caking agents are water-soluble liquid anti-caking agents, the requirements on the anti-caking agents sprayed on the surfaces of the fertilizers are higher, and the anti-caking agents added are required to be completely and uniformly wrapped on the surfaces of the fertilizers to achieve ideal anti-caking effects, so that a method for quickly judging the wrapping uniformity of the water-soluble liquid anti-caking agents on the surfaces of the fertilizers is established to have far-reaching significance for measuring the quality of the anti-caking effects.
The increasing of the full water-soluble fertilizers in the current market provides a method for rapidly judging the wrapping uniformity of the full water-soluble liquid anti-caking agent on the fertilizer, and is particularly important.

The method has the advantages of low cost, simple operation, convenient use, intuitive judgment, strong detection foundation and high reference practicability, can quickly judge the uniformity of the fully water-soluble liquid anti-caking agent coated on the fertilizer by using the reflected light of a fluorescent lamp after the fluorescent lamp irradiates on the surface of the fertilizer, can truly reflect the uniformity of the coated fertilizer on the surface of the fertilizer in the production process, can better guide the reasonable addition amount of the anti-caking agent in the production process, and ensures that the used liquid anti-caking agent is completely and uniformly coated on the surface of the fertilizer, thereby ensuring that the fertilizer is not caked, keeps loose for a long time, improves the appearance quality of the fertilizer, and is convenient to store and use.
The main technical problems to be solved by the invention are realized by the following scheme:
a method for rapidly judging the wrapping uniformity of a fully water-soluble liquid anti-caking agent on a fertilizer is characterized by comprising the following steps:
(1) adding fluorescent powder into a fully water-soluble liquid anti-caking agent according to the amount accounting for 0.05-0.2 percent of the liquid anti-caking agent, uniformly stirring for 10-30min to completely dissolve the fluorescent powder, and fully and uniformly mixing to ensure that the liquid anti-caking agent presents a corresponding color;
(2) spraying a certain amount of water-soluble liquid anti-caking agent on the surface of the fertilizer, and then taking 10-30 g of the granular fertilizer sprayed with the water-soluble liquid anti-caking agent; the uniform degree of surface wrapping of the fertilizer sprayed with the liquid anticaking agent is judged by using fluorescent lamp irradiation and through fluorescent reflected light reflected by the surface of the granular fertilizer;
(3) evaluation standard of wrapping uniformity: the surface of the fertilizer is irradiated by a fluorescent lamp, and when the whole surface of the fertilizer has uniform fluorescent reflection light, the liquid anti-caking agent is completely and uniformly wrapped on the fertilizer, so that the anti-caking effect is relatively good; when the surface of the fertilizer partially generates fluorescence reflection light, the anti-caking agent on the surface of the fertilizer is not uniformly wrapped, and the anti-caking effect is relatively poor; when the fluorescence reflection light is not seen on the surface of the fertilizer, the liquid anticaking agent is not added on the surface of the fertilizer, and the fertilizer is easy to agglomerate.
The stronger the fluorescence reflection light, the larger the surface area of visible light on the surface of the fertilizer, which shows that the more the wrapping addition amount of the liquid anti-caking agent is, the better the anti-caking performance is; on the contrary, the fluorescence reflection light is weak, and the smaller the surface area of visible light on the surface of the fertilizer, the smaller the wrapping addition amount of the liquid anti-caking agent is, and the anti-caking performance is poorer.
