Description
Technical field
The present invention relates to a kind of anti-hard caking agent, particularly a kind of anti-hard caking agent of water soluble nitro composite fertilizer.
Background technology
In recent years, along with wideling popularize compound fertilizer of high concentration, mechanization of agriculture fertilising is universal in addition, and the demand of Water soluble fertilizer strengthens gradually, and also day by day improves the requirement of Water soluble fertilizer.Composite fertilizer is in storage, handling and transportation or under specific ambient conditions, to lose flowability gradually and inter-adhesive and form lump, compound fertilizer from caking not only affects product appearance quality, and cause the very big inconvenience of use, particularly the water soluble nitro composite fertilizer of powdery is the chemical fertilizer of easy crystallization, its particle diameter is little, specific surface area large, therefore has more serious caking tendency.The fertilizer of caking must carry out fragmentation and sieve process again, this thereby necessarily increases extra-pay, result also in the loss of fertilizer simultaneously, cause have a strong impact on the survival and development of chemical fertilizers production enterprise.
In order to address this problem, producer of most of composite fertilizer all employs anti-hard caking agent in the process of production composite fertilizer, and the anti-hard caking agent existed at present can be summarized as following several:
1. inert powder is the anti-hard caking agent used the earliest, by mechanical isolation and absorption chemical fertilizer surface-moisture, thus realize preventing blocking effect, but inert powder consumption is large, for the powdery composite fertilizer of easily luming, preventing blocking effect is bad, and raw material is inert substance, is not suitable for the anti-caking process of water soluble composite fertilizer;
2. inorganic salt dispersants has preventing blocking effect because of its water-absorbent, but the moisture absorption point of Hui Shi composite fertilizer reduces greatly;
3. tensio-active agent-polymer Compositional type liquid anti-agglomeration agent, by reducing the surface tension of solution, change crystal habit, but synthesis technique is complicated.
At present, domestic commercially available anti-hard caking agent has following shortcoming: consumption is large, not easily degrades; To environment, preventing blocking effect does not reach requirement yet; Complete processing is complicated, and cost is high.In sum, existing anti-hard caking agent is not all suitable for the anti-caking process of water soluble composite fertilizer.
Summary of the invention
The object of the present invention is to provide a kind of consumption is few, cost is low, preventing blocking effect is good, be convenient to suitability for industrialized production pulverulent water-soluble anticaking agent for nitrocompound and preparation and application thereof.
Pulverulent water-soluble anticaking agent for nitrocompound of the present invention forms by several material is composite, and the mass percent wt% of each component is: tripoly phosphate sodium STPP 8 ~ 40%, sodium lauryl sulphate 10 ~ 35%, Sodium dodecylbenzene sulfonate 15 ~ 35%, polyacrylamide 8 ~ 30%.
Described polyacrylamide to be molecular weight be 5,000,000 polyacrylamide.
The preparation method of above-mentioned water soluble nitro compound fertilizer anticaking agent:
By raw mill to 300 order of above-mentioned anti-hard caking agent, obtain the anti-hard caking agent of powdery.
The using method of above-mentioned water soluble nitro compound fertilizer anticaking agent:
During use, water soluble nitro compound fertilizer anticaking agent is fully mixed by seed-coating machine with composite fertilizer, in composite fertilizer per ton, add 2 ~ 8kg water soluble nitro compound fertilizer anticaking agent.
The present invention compared with prior art tool has the following advantages:
(1) consumption of anti-hard caking agent is few, and cost is low;
(2) simple to operation, be convenient to suitability for industrialized production;
(3) preventing blocking effect is good, can make the shatter value of powdery Water soluble fertilizer more than 90%;
(4) anti-hard caking agent of the present invention, except having anti-caking effect, also has certain slow-release function;
(5) raw material used in the present invention is the material of easily degraded, can not cause environmental pollution.
