Description
Technical field
The present invention relates to the boron fertilizer production in the agricultural cience and farming techniques, particularly a kind of instant boron fertilizer and preparation method thereof.
Background technology
Boron is as one of necessary nutritive element of growth and development of plants, and is very important in agriculture production.In the required trace element of plant, the shortage of boron is the most general, and crop is also very urgent to the demand of boron.Investigation shows, plough reach more than 700,000,000 mu of serious boron deficiency of China accounts for nearly 40% of China's cultivated area.If do not use boron fertilizer on these are ploughed, serious boron deficiency symptom can appear in most of crops, as " the rotten worry " of beet, " colored and unreal " disease of cotton, and " flower bud and do not spend " diseases of rape etc. also have nearly 500,000,000 mu of slight boron deficiencies of arable soil in addition.Can not produce tangible boron deficiency symptom though on these are ploughed, plant plant, can influence the yield and quality of crop.As seen China's all boron deficiencies of ploughing more than 70%.The fruit tree of China all is planted in more on the barren mountain region still more, and the shortage of boron is even more serious.Therefore using boron fertilizer in China's agriculture production on a lot of areas and crop has been a kind of measure routinely.
At present, the boron fertilizer of China's production mainly contains following several:
1, borax: adopt the production of carbon alkaline process with magnesium borate ore.
2, boric acid production has two kinds of methods: the direct and sulfuric acid reaction of magnesium borate ore also claims single stage method.Another kind is to be raw material and sulfuric acid reaction with the borax, also claims two step method.
3, crystalline boron fertiliser containing magnesium: the byproduct that is magnesium borate ore single stage method manufacture boric acid.
4, particle boric magnesium fertilizer: with borax boron mud is raw material, through operation productions such as pulverizing, acidolysis, granulation, dryings.
How present boron fertilizer production mix under hot conditions for a long time with borax and boric acid reacts, and needs a large amount of heat energy, and production cost is very high, is unfavorable for the energy-saving and emission-reduction work of enterprise; And the production time is generally long, contracts and reaction needed 2～8 hours, and production efficiency is lower, and product competitiveness is low, is unfavorable for market competition.The boron fertilizer kind of generally using in the market is because problem such as it is poorly soluble, specific absorption is low, potential of hydrogen is not suitable for is made troubles to agriculture production.
Adopt microwave heating to have characteristics such as rate of heating is fast, calorific loss is little, easy to operate, both can shorten the process time, boost productivity, reduce cost, can improve the quality of products again.Compare with traditional heating mode, microwave heating has following characteristics: homogeneous heating, speed are fast.General heating means rely on the environment of circumference, make object surfaces obtain heating earlier with the radiation of heat or the mode by hot-air convection, then the inside by thermal conduction conduction object.This method efficient is low, and heat-up time is long.The maximum characteristics of microwave heating are, microwave is in the inner generation of heating object, thermal source is from interior of articles, homogeneous heating, can not cause the half-cooked phenomenon of " not yet done in outer Jiao ", help improving the quality of products, simultaneously because " heat simultaneously the inside and outside " shortened heat-up time greatly, the heating efficiency height helps improving product production.The inertia of microwave heating is very little, can realize the quick control of gradient of temperature, helps continuous production ground volume and controls automatically.
Summary of the invention:
The object of the present invention is to provide that a kind of production is energy-conservation, production efficiency is high, its boron content height, quick-acting, quick-dissolving instant boron fertilizer and preparation method thereof.The pure boron content of instant boron fertilizer that the present invention produces reaches 18%, under the working concentration prerequisite, can be dissolved in fully in 60 seconds in the cold water under the room temperature.
In order to realize the foregoing invention purpose, the technical scheme of employing is as follows: instant boron fertilizer, make 5～7 parts of boron trioxides, 5～7 parts of boraxs, 1～3 part of initiator, 4～6 parts of boric acid by following raw material weight component;
Described initiator is made according to the following steps by following raw material:
1. with 4～9 parts of raw material boric acid, 5～11 parts of glycerine component are by weight packed into and are mixed in the container;
2. said vesse is placed the solution pool of ultrasonic generator;
The frequency that 3. ultrasonic generator is set is carried out ultra-sonic oscillation at 20～40KHz to mixture, and the viscous fluid that the material in container is no visible crystals promptly obtains described initiator.
The manufacture craft of instant boron fertilizer of the present invention may further comprise the steps:
(1) with raw material by weight component mix, carry out the intermittent type issuance of materials, when material becomes even lotion, promptly get work in-process;
(2) work in-process are carried out micro-wave drying,,, stop drying to moisture content≤5% o'clock 110～130 ℃ of dryings;
(3) pulverize after naturally cooling to room temperature, after screening 80～150 purpose screen clothes, obtained finished product.
Described mixed processes carries out in conical twin-screw mixer or ribbon mixer.
Described pulverizing process wherein carries out in one or more at hock type pulverizer, cutter formula pulverizer or turbine type pulverizer.
Described screening process vibratory screening apparatus, rocking sieve or revolve shake the sieve wherein carry out in one or more.
The present invention has following beneficial effect:
1, add initiator in the production of instant boron fertilizer, various raw materials just can be reacted under general condition, do not need the pyritous condition, saved a large amount of heat energy, reduced production cost, help the energy-saving and emission-reduction work of enterprise, product competitiveness is strong.
2, in the production of instant boron fertilizer, add initiator, effectively shortened the time that condensation reaction needs, enhance productivity.
3, instant boron fertilizer makes in dissolution process because of its particle contains numerous aperture, and moisture can penetrate into the particle center rapidly along aperture, be dissolved in inside and outside two aspects and carry out simultaneously thereby make, so particle can reach quick dissolving, and nutrient discharges rapidly.
4, in the production of instant boron fertilizer, adopt microwave heating to have characteristics such as rate of heating is fast, calorific loss is little, easy to operate, both can shorten the process time, boost productivity, reduce cost, can improve the quality of products again.
5, instant boron fertilizer finished product is a borate, and the aqueous solution is fit to mix use with any chemical pesticide near neutral, does not exist soil is polluted with environment, and ecotope is not worked the mischief, and has good ecological benefits, reduces peasant's labour intensity.
6, instant boron fertilizer has the deficiency of additional root fertilising as foliage fertilizer, supplements the nutrients rapidly, gives full play to fertilizer efficiency, economical effect.It is fast to reach absorption, and effect is strong, and is low-consuming, the effect that efficient is high.
7, instant boron fertilizer can improve bound water content in the plant materials, strengthens its resistance, helps improving plant drought, cold-resistant, heat impedance, resistance against diseases.
8, the synthetic and utilization of growth hormone in the instant boron fertilizer involved in plant body promotes root growth.
9, instant boron fertilizer can be regulated the plant balance and absorbs other nutritive elements, improves output.
10, carbohydrate, protein transportation and metabolism in the instant boron fertilizer involved in plant body improves crop quality.
