Abstract

The invention discloses an enveloped potassium added urea and fabrication method thereof, wherein the urea comprises 55-70% of urea, potassium oxide 25%-35%, organic matter 5-10%, and the external surface of the product comprises 100% films including pest resisting organic oil 0.2-0.4%, resin film 0.4-1.3%, the preparing method comprises mixing the constituents, drying, and mixing into film forming agent.

Description

Coating adds potassium urea and preparation method thereof

Technical field

The present invention relates to a kind of improvement that existing chemical fertilizer and manufacturing process thereof are carried out.

Background technology

Before the present invention realized, the nitrogenous fertilizer that people use to farm crop was mainly urea, and this chemical fertilizer can effectively promote the growth of farm crop, and with low cost, used conveniently.But urea is xln, and volatilization easily and has irritating smell at normal temperatures, and people feel very uncomfortable when fertilising.Transportation, in the storage process urea goods harden easily, volatilization naturally, and then cause fertilizer efficiency decline, plant absorbing amount little.Just chemical fertilizer is simply spread in the ground when particularly people apply fertilizer now, so not only, reduced the service efficiency of chemical fertilizer, increased the production cost of farm crop because the volatilization of chemical fertilizer causes unnecessary waste, and polluted environment, the healthy of user impacted.In addition, well-known potassium is obvious and indispensable to the influence that farm crop grow up, must application of potash fertilizer to farm crop, this is people's a common recognition, but past people generally all is the work method that adopts independent application of potash fertilizer of difference and nitrogenous fertilizer when fertilising, not only labour intensity is big, inefficiency, and increased the production costs of farm crop.

Technology contents

The objective of the invention is by providing coating to add potassium urea and preparation method thereof, and then solved the problem that exists in the above-mentioned background technology.

In the technical solution of the present invention, in adding the composition of potassium urea, described coating contains urea 55-70%, Repone K 25-35%, organic 5-10%; The outside surface of described goods is coated with that to contain with aforementioned proportion be the coating of organic oily 0.2-0.4%, resin molding 0.4-1.3% of 100% preventing disease and pest.

Described coating adds the making method of potassium urea, it is batching that its technical process is mainly with urea 55-70%, Repone K 25%-35%, organic 5-10%, mix in the back input tablets press, granulation under the condition of 3-5 minute, 38-54 ℃ is dried under 55-88 ℃ condition then; To be that 100% preventing disease and pest organic oily 0.2-0.4%, resin molding 0.4-1.3% are mixed into the coating agent with aforementioned proportion, under the condition of 2-4 minute, 50-60 ℃, carry out coating, carry out such as postprocessing working procedures such as drying, weighing, packings then with coating machine.

In above-mentioned technology contents of the present invention, described degree is the weight percent of finished product, uses the conventional producing apparatus in the background technology in the described manufacturing process

Manufacture method of the present invention is simple, to after adding potassium urea and carrying out coating, can overcome effectively in the past that the urea goods harden easily in transportation, storage process, volatilize naturally, and then cause fertilizer efficiency to descend, problem that the plant absorbing amount is little, fertilizer efficiency is improved greatly, also make simultaneously its pollution drop to minimum degree, can ensure that the peasant's is healthy environment.When using, can once use two kinds of fertilizer simultaneously and improve efficiency greatly, the output of agricultural-food and quality are significantly improved, also reduced the production cost of agricultural-food.

Embodiment

Below in conjunction with specific embodiment, technology contents of the present invention is elaborated:

Embodiment 1

After getting homemade urea 65%, Russia's product Repone K 28%, organic 7% mixing, send in the conventional tablets press, granulation is 3.5 minutes under 42 ℃ condition, dries 3.5 minutes down at 60 ℃ with the drying plant of routine then.Send into conventional coating machine behind the work in-process process sub-sieve through above processing.The organic oil 0.3% of commercially available preventing disease and pest, nontoxic resin molding 1.3% are added in the coating machine as the coating agent, under 54 ℃ condition, worked 2.5 minutes.Pack after at room temperature drying then.

Adopt the coating of this case making to add potassium urea, use on booth vegetable ground, per half mu is used 17Kg to topdress, and can make the single use urea of celery rate ratio make fertilizer volume increase 200Kg.

Embodiment 2

After getting homemade urea 57%, Russia's product Repone K 35%, organic 8% mixing, send in the conventional tablets press, granulation is 4.5 minutes under 40 ℃ condition, dries 3.5 minutes down at 63 ℃ with the drying plant of routine then.Send into conventional coating machine behind the work in-process process sub-sieve through above processing.The organic oil 0.4% of commercially available preventing disease and pest, nontoxic resin molding 0.4% are added in the coating machine as the coating agent, under 58 ℃ condition, worked 3 minutes.Pack after at room temperature drying then.

Adopt the coating of this case making to add potassium urea, use at corn field, every mu is used coating to add potassium urea under same case, can make corn yield make fertilizer volume increase 200Kg than single use urea.

Embodiment 3

After getting homemade urea 62%, Russia's product Repone K 31%, organic 7% mixing, send in the conventional tablets press, granulation is 5 minutes under 48 ℃ condition, dries 3.5 minutes down at 85 ℃ with the drying plant of routine then.Send into conventional coating machine behind the work in-process process sub-sieve through above processing.The organic oil 0.2% of commercially available preventing disease and pest, nontoxic resin molding 0.6% are added in the coating machine as the coating agent, under 54 ℃ condition, worked 4 minutes.Pack after at room temperature drying then.

Adopt the coating of this case making to add potassium urea, use, in 30 * 7 meters area, make radish yield make fertilizer volume increase 100Kg than single use urea on radish ground.
