Description
[technical field]
The present invention relates to a kind of compound fertilizer anticaking agent, particularly a kind of straw powder based anti-blocking agent of compound fertilizer.
[background technology]
Along with the development of agricultural, single nutrient chemical fertilizer can't be met the need of market, and the composite fertilizer of efficient, many kinds of multielement special fertilizer, especially high-quality is just more and more favored.
Caking is ubiquitous phenomenon in chemical fertilizers production, transportation and the storage process, is perplexing the fast development of fertilizer industry always.Caking has brought very burden to composite fertilizer's storage, transportation and use equally, and has a strong impact on fertilizer efficiency.The correct agglomeration problems that solves is one of effective way that improves chemical fertilizer products quality and cost performance.Prior art shows that (see Chinese patent for details, open day is on October 30th, 2002, and publication number is the patent " anti-coagulating agent for composite fertilizer " of CN1376653A; Open day is on January 14th, 2004, and publication number is the patent " potassium nitrate anticaking agent " of CN1467156A; Open day is on August 3rd, 2005, and publication number is the patent " powdering and caking resisting agent for urea " of CN1648110A; Open day is January 30, publication number is the patent " a kind of ammonium chloride anti-caking agent and the application in preparation anti-caking ammonium chloride thereof " of CN101112997A etc.), except taking measures in composite fertilizer's production, packing, transporting procedures, adding anti-hard caking agent in the fertilizer is the most effective anti-caking method.In various anti-caking methods, what current composite fertilizer manufacturer generally adopted is that face powder, coating or coating add the face powder technology, wherein with the coating treatment technology use at most.
Face powder mainly is to make the inert substance powder evenly be adsorbed on the fertiliser granulates surface to alleviate anti-caking, and inert substance commonly used has clay, diatomite, kaolin, wilkinite, zeolite, talcum, potash feldspar, sepiolite, Wingdale, phosphorite powder, brown coal powder, coal ash powder, plant ash powder and quartz sand etc.This method cost is lower, but exists following deficiency: (1) Dust Capacity is large, severe operational environment; (2) preventing blocking effect is not good; (3) inert substance is difficult to natural decomposition, life-time service, and richness is amassed in soil the strong effect ecological environment of soil easily.
Coating mainly is to adopt hydrophobic organic compound or tensio-active agent that fertiliser granulates is carried out surface to coat and form the hydrophobicity rete, play fertiliser granulates is isolated from each other and with the effect of on every side water vapour isolation, lump preventing.Hydrophobic organic compound commonly used mainly contains: machine oil, mineral oil, heavy oil, pitch, paraffin, Vaseline etc., and wherein machine oil (mostly being greatly discarded refiltered oil) consumption is maximum; Tensio-active agent commonly used mainly contains: aliphatic amide, lipid acid and sodium salt thereof, fatty sulfonic acid and sodium salt thereof, fatty phosphoric acid and sodium salt thereof etc., wherein lipid acid and aliphatic amide large usage quantity.Compare with face powder, it is more even that coating is processed, better to the effect of the anti-caking of chemical fertilizer, especially still can keep certain agglomeration resistance effect under higher humidity, but also exist following deficiency: (1) when envrionment temperature was low, preventing blocking effect was good, and when temperature was higher, effect was not good enough; (2) use the alkanes oil that is difficult in a large number natural decomposition, not only affect the water-soluble of chemical fertilizer, and Reusability meeting contaminated soil; (3) the synthetic reagent raw material of employing larger specific gravity, cost is relatively high, and brings easily harmful toxic matter contaminated soil and crop into.
On overall, no matter be face powder anti-hard caking agent or coating anti-hard caking agent, preventing blocking effect is all more general, and validity is no more than 6 months usually, and As time goes on, preventing blocking effect worse and worse, caking trend is more and more serious.Coating is combined with the face powder technology, the compound anti-hard caking agent that obtains, has good agglomeration preventing performance, but also have higher cost performance, with compound anti-hard caking agent for the treatment of chemical fertilizer, be conducive to improve the quality of composite fertilizer, therefore, comprehensive anti-hard caking agent is current and even the emphasis that study for a long period of time from now on.
And crop material is important Biological resources in the farm crop production system, also is the fourth-largest energy that is only second to coal, oil and natural gas in the world today.All kinds of crop stalks of China are very abundant, but how by direct returning to farmland, or as industrial raw material such as fuel, papermaking, feeds, utilising efficiency is very low.Expansion Ways, green, make good use of stalk efficiently, fully, and cultivate and develop new Agricultural Economic Growth point, become the problem demanding prompt solution that modern agriculture faces.
[summary of the invention]
The technical problem to be solved in the present invention is to provide a kind of straw powder based anti-blocking agent of compound fertilizer, and it does not need to use machine oil, and environmental protection, processing is easy, cost performance is high.
