Description

The production method of composite multi-functional High hydrophilous resin

Technical field

The present invention relates to nitrogen, phosphorus, three kinds of nutrient substances of potassium and High hydrophilous resin by the new generation product of the synthetic a kind of water-saving fertilizer-preserving of kinds of processes flow process, specifically a kind of production method of composite multi-functional High hydrophilous resin.

Background technology

China is the country of a lack of water, water resources lacks extremely, the Northwest particularly, lack of water is serious especially, Desertification increasing year by year, vegetation deterioration is serious, is badly in need of a kind ofly can in farm crop application, playing the effect of volume increase on market, again can be at sand control and sand stabilization, play very large effect innovative product on planting trees, improving the ecological environment.

Summary of the invention

Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, a kind of production method of composite multi-functional High hydrophilous resin is provided, the technical solution adopted for the present invention to solve the technical problems is: the first step, the ratio of the mass ratio of nitrogen, phosphorus, potassium, High hydrophilous resin is respectively, nitrogen accounts for 12%, phosphorus accounts for 18%, potassium accounts for 12%, High hydrophilous resin accounts for 58%, first according to said ratio ratio, nitrogen, phosphorus, potassium are mixed with powder-form, then add according to the above ratio High hydrophilous resin that gained mixing raw material is entered to blending bun stirring and evenly mixing at normal temperatures; Second step, the raw material that the first step is obtained adds puts into extrusion machine after water or disk pelletizing machine is granulated, and makes the particle of diameter 4-5mm according to required specification; The 3rd step, the particle that second step is obtained enters vibratory screening apparatus sorting particle, and diameter is 4-5mm, and remaining utilizes vacuum fan to reenter feed bin and pulverizes rear secondary granulation, and the particle screening is exactly work in-process; The 4th step, the work in-process particle that the 3rd step is obtained is at wind cold drying case inner drying, and temperature is at 90-95 ℃, and dry object is to remove the humidity of particle, makes particle finish-drying; The 5th step, utilizing coating machine particle coating is that after coating completes, product becomes white circular shape finished granule in order to make dry granules more round and smooth.

High hydrophilous resin is a kind of new functional macromolecule material, there is hydrophilic radical, can absorb in a large number moisture and swelling can maintain the synthetic resins that moisture does not outflow, as starch grafted acrylate class, graft acrylamide, high substitution value cross-linked carboxymethyl cellulose, cross-linked carboxymethyl cellulose graft acrylamide, cross-linking type Natvosol graft acrylamide polymkeric substance etc., generally can absorb and be equivalent to 100 times of above moisture of resin volume.

The invention has the beneficial effects as follows, the product tool that the production method of composite multi-functional High hydrophilous resin is produced has the following advantages, and is embodied in:

One, improvement soil: can improve the ventilation property of soil, excite the vigor of microorganism; thereby crumb structure in raising soil, conditioning soil, forms the effective environment that is beneficial to microorganism existence; soil is improved; thereby make not slope knot of soil, in addition, alkali plant; apply this product and can form a pressure alkali antiseepage protective layer; make full use of water on the ground, and push down Underground Alkaline and rise, crop is grown well.

Two, drought-resistant water-preserving: this product can store rainwater, snow-broth, irrigation water and various nutrition absorption slow release 2-3 month, forms a miniature reservoir around at crop root, reduces seepage and loss, thereby has reached the object of saving water, resisting drought.

Three, promote growth: this product is rich in various nutrient elements and all kinds of organic matter, can promote crop growth, premature ripening, and the integrated production capacity of soil is improved, the photosynthesis that strengthens crop, has effect of increasing production, improves the content of starch in gourd, fruit and vegetable, protein, VITAMIN simultaneously; Melon and fruit sugariness increases, and fruit is rectified, mouthfeel is good, the best fruiting period is long, and can go on the market ahead of time.

Four, fertilizer conservation synergy: water-holding agent, owing to absorbing and keeping the effect of moisture, can reduce the leaching loss of leaching nutrient to a certain extent, mixes and uses the effect that can play Synergistic slow release with chemical fertilizer, agricultural chemicals.As the saying goes: " have and receive without being received in water, receive many receipts and be less fertilizer ", water-holding agent can be coordinated water and fertilizer coupling environment, significantly improves nitrogen, phosphorus, potassium utilization rate.

Five, solution is hardened: after this product is manured into soil, due to water-swelling, increased liquid phase of soil ratio, reduced gas phase ratio, improved soil water thermal conditions, arid is released water contraction, can make soil become loose by consolidation, improves the ventilation property of soil, fertilizer efficiency significantly improves, and makes soil become fertile.

Six, water retention capacity: this product can and save the usual moisture absorption due to evaporation, seepage, loss, slowly discharges when plant needs.

Seven, repeated action: this product has stronger anti-uv-ray can significantly increase work-ing life in utilization process, after adsorbed moisture is discharged, as runs into moisture adsorption swelling again, can repeatedly inhale to discharge water minute in soil.

Eight, applied range: this product, at all kinds of soil, can keep high stability and high efficiency under each kind of plant and Different climate condition.

Nine, easy to use: this product is identical with plain particles type fertilizer usage in use, after spreading fertilizer over the fields, turn over or ditch spread, spread manuer in holes, execute rear timely earthing, follow the principle of " early execute, closely execute, evenly execute ", consumption is larger, and effect is better, has no side effect.
