Abstract
The invention discloses a coal gangue composite soil conditioner and a manufacturing process thereof. The raw material components comprise coal gangue, sodium hydroxide, waste polyurethane foam plastic, phosphoric acid, potassium chloride, urea and the like. The foamed plastic is softened and split into particles, the foamed plastic particles, the materials after the neutralization reaction of the coal gangue and the sodium hydroxide, the potassium chloride and the urea are sequentially added into a stirrer, and the particles prepared after stirring and adsorption are sent into a converter to be dried, so that the foamed plastic is prepared.
Description
The present invention relates to a kind of is the composite soil modifier and the manufacturing process of main raw material with the coal gangue, is widely used in the improvement of various farmlands soil property, as saline-alkali soil, spongy soils,
The improvement of native, yellow moisture soil, sandy soil, cement mortar black earth, sandy loam matter cinnamon soil, brunisolic soil, Baijiang soil, carbonate purple soil, calcareous alluvial soil, moisture soil, loess, saline soil, grey desert soil, red soil etc.
Increase along with the chemical fertilizer usage quantity, long-term application can make soil compaction, appearing at of humic acid fertilizer solved this problem to a certain extent, thereby for fertilizer has been opened up broad application prospect in the application of improving the soil etc., but because the restriction of resource, the price comparison height of humic acid fertilizer, thus limited its widespread use.
The objective of the invention is to overcome weak point of the prior art and provide a kind of raw material resources abundant, cost is low, and technology is simple, has the gangue compound land improving agent and the manufacturing process of the improvement and the effect of fostering and apply fertilizer.
The object of the present invention is achieved like this: the feed composition of gangue compound land improving agent and shared raw material weight per-cent thereof are:
Colliery powder 90-97.5
Sodium hydroxid (98% solid caustic soda) 0.5-1
Waste and old polyurethane foam 1.2-2.5
Phosphoric acid (concentration 98%) 0.65-1.25
Repone K 0-5
Urea 0-5
Its manufacturing process is: each feed composition is converted into by content and after the weight real number is prepared burden waste and old polyurethane foam fragment is immersed in the phosphoric acid solution that softening to split into particle standby, colliery powder mixes with 5% sodium hydroxide solution and closes reaction in carrying out, then foam grain, in close reacted coal gangue material, Repone K, urea and add stirrer successively and carry out making particle after the whip attachment, again particle is sent into converter and is dried and promptly make gangue compound land improving agent.
Purpose of the present invention can also realize by following measure:
The optimum feed stock component (weight %) of gangue compound land improving agent is:
Colliery powder 95.47
Sodium hydroxid (98% solid caustic soda) 0.72
Waste and old polyurethane foam 1.9
Phosphoric acid (98%) 0.95
Repone K 0.48
Urea 0.48
The processing parameter of making modifying agent is that the dipping temperature of waste and old polyurethane foam is a normal temperature, and the dipping splitting time is 20-30 minute; Colliery powder and sodium hydroxide solution hybrid reaction temperature are normal temperature, reaction times 20-30 minute; Various mixing of materials stir, be adsorbed on normal temperature condition does not carry out churning time 15-20 minute; Particle drying temperature (converter temperature) is 60-80 ℃, and how much decide with material time of drying.
Reaction mechanism: close generation humic acid in reaction back in colliery powder and the sodium hydroxid and receive, form humic acid fertilizer, the porous plastics phosphate impregnation makes the softening small-particle that splits into of blocky polyurethane foam fragment, replaced mechanical workout, this particle has formed the nuclear of modifying agent.
The present invention compares background technology and has the following advantages:
1, raw material resources are abundant, and cost is low;
2, technology is simple;
3, be a kind of soil improvement agent, can be used as fertilizer again uses, using this modifying agent through 3 years experiment showed,, to have reduced soil molten heavy, increased the soil total porosity, increased the cation exchange capacity of soil, thereby improved the drought-resistant ability of farm crop,, also just improved the cement of soil, dried, stiff degree because the logical transparency of soil and fertilizer supply and preservation performance increase, thereby just cause promoting growing of crop, improve crop yield;
4, this modifying agent is a kind of organic substance, be manured into soil after microbiological degradation transforms again synthetic complicated organic colloid, contain solubility egg protein and humic acids, have moderate cohesiveness, can make clay loose, the sand bonding forms crumb structure, and contain multiple nutrient, help activity of microorganism and the growth of plant, it possesses the fertilizer efficiency of the fertilizer of organic and inorganic fertilizer, is good soil improvement agent.
Below in conjunction with embodiment in detail the present invention is described in detail:
The feed composition of embodiment and shared weight percent such as following table:
Feed composition | Weight % |
Fill a prescription two the prescription three | |
The waste and old polyurethane foam phosphoric acid of colliery powder sodium hydroxide Repone K urea | 95.47 96 95.5 0.72 0.5 1 1.9 1.2 2.3 0.95 0.65 1.2 0.48 0.85 0 0.48 0.8 0 |
Above-mentioned each percentages of ingredients content is converted into the weight real number prepares burden, as being by the prescription one weight real number that is converted into:
Feed composition weight (kg)
Colliery powder 1000
Sodium hydroxid 7.5
Waste and old polyurethane foam 20
Phosphatase 11 0
Repone K 5
Urea 5
At first with 20 kilograms waste and old polyurethane foam fragment with 10 kilograms 98% phosphoric acid solution dipping division 20-30 minute, be as the criterion to split into small-particle fully; Be mixed with 5% solution and mix with 1000 kilogram of 80 purpose colliery powder and close reaction in carrying out 7.5 98% sodium hydroxid of kilogram adds water, about 25 minutes time, then foam grain, in close reacted coal gangue material, 5 kilograms of Repone K, 5 kilograms of urea and add successively in the stirrer and stirred 15 minutes, make plastic grain generation static that coal gangue material, Repone K, urea are attracted to particle surface formation particulate state modifying agent owing to stir friction, send into again in 60-80 ℃ the converter and dry, promptly make product.
Repone K, urea are inorganic chemical fertilizer, and along with the increase fertilizer efficiency of addition improves thereupon, but cost also increases thereupon, generally is no more than 5% and is advisable.
