Abstract
The invention discloses a film coating technology of humic acid fertilizer, belonging to the field of organic fertilizer processing and relating to a new organic fertilizer processing method. By means of coating a humic acid particle with a film, the particle hardness is increased, the friction coefficient is reduced, the particle pulverization rate is lowered to be below 1% from over 30% of the current year, and a fertilizing pipe is not blocked. Therefore, the application rate of the humic acid can be increased under the current situation that the structure of the existing seeding machine is not changed and beneficial conditions are provided for application of a large quantity of humic acid for improving soil and producing pollution-free food. The quality guarantee period of the humic acid particle is prolonged by one year. A selected film forming agent which is most appropriate for coating the humic acid particle is polyvinyl alcohol. The film coating technology comprises the concrete operation procedures of: heating 500kg of water to 90 DEG C, adding 25kg of polyvinyl alcohol, evenly stirring for dissolution until the mixture is transparent without impurities, and spraying mist for film coating by using a film spraying machine after the temperature is reduced to be below 40 DEG C, wherein 60kg of humic acid particles can be coated by 1kg of film forming agent solution.
Description
Technical field
The present invention relates to a kind of organic fertilizer production manufacture field, especially relate to a kind of humic acid fertilizer mantle.
Background technology
Along with the raising of people's living standard, environmental consciousness strengthens, and is more and more higher to the Organic food requirement of pollution-free, noresidue, safety, high-quality, also more and more higher to the specification of quality of capital goods in the agricultural sector.Fertilizer is the extremely important production means in agriculture production, and the output that namely affects agricultural prods affects again the quality of product.In recent years to not only increasing production but also can to propose high-quality fertilizer requirement more and more stronger.Yet all designed for using inorganic fertilizer with the supporting fertilizing equipment of seed sower in the past.During application of organic fertilizers, because the fertilizer effective content is few, requirement is large, does not often reach rate of fertilizer application, although more directly use pulvis to increase amount of application by granulation, the humic acids particle of conventional machining has following disadvantage: 1, frangible.Due to rough, the friction of transportation fertilising process is frangible, and general degradation rate reaches more than 30%.2, the powder of crushed particles generation usually stops up the fertilising pipe, does not reach the fertilising requirement, increases production cost.3, limited use range.Because the humic acids particle that routine is produced is frangible, can not reach production requirement with the composite fertilizer of chemical fertilizer mixing manufacture.Produce the problems referred to above anxious to be resolved.
The conventional humic acids particle of producing in the market, anti-impact force, wear resistance are lower, do not reach production requirement with the fertilizer that mixes of chemical fertilizer mixing manufacture.
Summary of the invention
The objective of the invention is: for the problems referred to above, provide a kind of humic acids mantle fertile.It is to use film forming material to be wrapped in the humic acid fertilizer mantle that the humic acids particle surface makes.
Humic acid fertilizer mantle of the present invention comprises humic acids granule core and polyvinyl alcohol film forming material, and it prepares by following technique:
The first step: a certain amount of humic acids particle is placed in encapsulation tool;
Second step: water is heated to certain temperature, adds polyvinyl alcohol, stir evenly and dissolve, make membrane-forming agent solution;
The 3rd step: membrane-forming agent solution is cooling, with the Membrane jetter mantle of spraying.One jin of membrane-forming agent solution can overlap 60 kilograms of humic acids particles.
Embodiment
Humic acid fertilizer mantle of the present invention comprises humic acids granule core and polyvinyl alcohol film forming material, and it prepares by following technique;
The first step: the humic acids particle that routine is made is placed in encapsulation tool;
Second step: 500 kg of water are heated to 90 ℃ of temperature, add 25 kilograms of polyvinyl alcohol, stir evenly and dissolve, make membrane-forming agent solution;
The 3rd step: with cooling 40 degree of membrane-forming agent solution, with the Membrane jetter mantle of spraying.One jin of membrane-forming agent solution can overlap 60 kilograms of humic acids particles.
The fertile preparation of this mantle easily, application method is scientific and reasonable, anti-impact force, wear resistance are strong.Reduce agricultural pollution, improved utilization rate of fertilizer.
The above is the preferred embodiment of the present invention, should be pointed out that for this area, under the prerequisite that does not break away from the principle of the invention, can also make some changes and improvements, and these also should be considered as belonging to protection scope of the present invention.
