Abstract
The invention discloses a silico-calcium-containing high-efficiency potassic fertilizer and a preparation method thereof. The method comprises the following steps of: weighing the following raw materials in percentage by weight: 5 to 10 percent of polyving akohol, 5 to 10 percent of corn starch, 0.01 percent of copper sulfate powder, 0.01 percent of zinc sulfate powder, and 79.98 to 89.98 percent of water; mixing the raw materials, stirring at the reaction temperature of between 80 and 90 DEG C for 30 to 40 minutes at a rotation speed of 100 rpm to obtain an adhesive for later use; weighing oil shale clinker, calcium carbonate and potassium sulfate in a mass ratio of 4:0.5:5.5, drying the raw materials, and crushing into powder with 150-300 meshes; and uniformly mixing the powder, and granulating in a granulator by spraying the adhesive accounting for 20 to 30 mass percent of the raw materials. The preparation method has the advantages of simple process, readily available raw materials, long fertilizing time, high fertilizer utilization rate, low raw material cost and the like.
Description
One, technical field
The invention belongs to technical field of fertilizer, be specifically related to a kind of efficient potash fertilizer of silico-calcium and preparation method thereof that contains.
Two, background technology
Traditional chemical fertilizer application utilization ratio is low, also can the severe contamination physical environment.Given this develop slow release fertilizer both at home and abroad in succession, though this kind fertilizer has been obtained certain prolongation fertilizer efficiency effect.But the production technique of producing this kind fertilizer is comparatively complicated, and cost is higher, is difficult to form scale operation.
Oil shale (oil shale) is a kind of organic sedimentogeneous rock that contains, and it is 2,400,000,000 tons that China has verified resource.Along with resources such as world oil, Sweet natural gas are in short supply day by day, the oil shale development and use enlarge day by day, and a large amount of lime-ash of its industrial discharge are piled into the mountain, take a large amount of soils, have a strong impact on ecotope.The oil shale lime-ash contains SiO
2, organic and that plant is essential is a large amount of and micro-, be the good raw material of exploitation composite fertilizer, but do not utilized well for a long time, caused the waste of resource.
Three, summary of the invention
It is long to the purpose of this invention is to provide a kind of fertilizer efficiency time, and utilization rate of fertilizer is high contains the efficient potash fertilizer of silico-calcium.
Another object of the present invention provides a kind of preparation method who contains the efficient potash fertilizer of silico-calcium, this method is to be main raw material with the oil shale lime-ash, not only solved oil shale lime-ash land occupation, the problem of influence ecological environment, and also production technique is simple, cost is low.
For achieving the above object, the technical scheme taked of the present invention is:
One, the present invention---contain the efficient potash fertilizer of silico-calcium and make by following preparation method.
Two, the present invention---contain the preparation method of the efficient potash fertilizer of silico-calcium, comprise the steps:
1, preparation binding agent:
Take by weighing raw material according to following component and weight percent: polyvinyl alcohol 5%-10%; W-Gum 5%-10%; Copper sulphate powder 0.01%; Zinc sulphate powder 0.01%; Water 79.98%-89.98%; Above-mentioned raw materials is mixed, and under 80-90 ℃ temperature of reaction, stirred 30-40 minute with 100 rev/mins rotating speeds, it is stand-by to make binding agent;
2, preparation potash fertilizer:
Take by weighing oil shale lime-ash, lime carbonate and vitriolate of tartar respectively according to 4: 0.5: 5.5 mass ratioes, above-mentioned raw materials is carried out drying, and be ground into 150-300 purpose powder; With the gained powder mixes evenly after, add in the tablets press, spray into the step 1 gained binding agent that accounts for raw materials quality 20%-30% and carry out granulation, promptly get and contain the efficient potash fertilizer of silico-calcium.
Above-mentioned polyvinyl alcohol (PVA) molecular weight model is 1300-1800.
Above-mentioned W-Gum is that grade is a 30-40 purpose conventional corn starch.
The present invention contain the efficient potash fertilizer of silico-calcium be with cheap and easy to get, nontoxic, contain the crop essential nutrient element, oil shale lime-ash with soil improvement function is that main raw material is prepared from, the auxilliary lime carbonate that adds is with activation beneficial element silicon wherein, and by both mixing potassium sulphate fertilizer is wrapped up, to realize the purpose of controlled release potassium nutrition.This invention compared with prior art has following advantage: 1) technology is simple, and non-chemical industry synthesis technique utilizes conventional equipment and compound technology to finish, and can directly drop into existing fertilizer plant production, has reduced the equipment input, has reduced cost; 2) raw material is easy to get, and the caking agent composition is biodegradable, and environmentally friendly, and the degraded composition can improve Soil structure effectively; 3) adopt oil shale lime-ash and lime carbonate filler as potassium sulphate fertilizer, and add component such as trace element, the plant nutrient needs had both been satisfied, again can be with the physical barriers of its as fertilizer sources nutrient release, prolonged time for fertilizer, improve utilization rate of fertilizer and reduced raw materials cost, increased economic benefit.Simultaneously, reduce lime-ash land seizure amount, protected ecotope.
