Abstract
Ammonium bicarbonate fertilizer with integument is a kind of bicarbonate of ammonia to be rolled into big and hard particles through the roll-type tablets press, is main film forming matter on its surface in order to pitch, with the slow nitrogenous fertilizer that the bicarbonate of ammonia particle wraps up, reduces the loss to reach, and improves the purpose of fertilizer efficiency.
The coated fertilizer manufacturing process adopts pitch to add that the solution that gasoline or dimethylbenzene are mixed with the mineral filler is film forming matter, is coated in through rolling bicarbonate of ammonia particle surface, will be finished product after the film forming matter drying.
Description
The invention belongs to the chemical industry class, particle coated fertilizer and manufacturing process thereof.
Coated fertilizer belongs to a kind of of granulated fertilizer.Coated fertilizer is that one or more chemical fertilizer materials are made particle by machinery or chemical process, with water-fast material, controls the release rate of fertilizer in its surface applied, reduces fertilizer loss, improves utilising efficiency.
United States Patent (USP) и о .3697245(contriver: about plucked instrument Fitow Dai Er gets Josepn TDilday and ratifies day on October 16th, 1972.International patent C05C9/00) introduced and a kind ofly Granular Urea is constantly rolled in cement blender and add used oil, the solution of calcium lignin sulphonate and the coating method of sulphur powder.
Above-mentioned coated fertilizer manufacturing process is applicable to the urea that grain size number is bigger, is not suitable for the thinner bicarbonate of ammonia of grain size number.
The objective of the invention is to make a kind of release rate that with nitrogen is the cheap coated fertilizer of main nutrient elements with control nitrogen, make it become slow-release fertilizer, reduce fertilizer loss, increase operation rate the volatilization and the agglomeration problems that reduce and avoid fertilizer to store.
The method of solution task is to be rolled into bigger and hard bicarbonate of ammonia particle through the roll-type tablets press be core; is main film forming matter in its surface applied with pitch; be that solvent mixes with the mineral substance with gasoline or dimethylbenzene be the solution of filler, and be finished product after the film forming matter drying with its particle surface.
The coated fertilizer manufacturing process is as follows:
At first prepare film forming liquid.Take by weighing a certain amount of pitch, in vessel in heating fusing dehydration, ceasing fire cools to 120～170 ℃, will a certain amount of gasoline or dimethylbenzene add in the container and stir, mix a certain amount of mineral filler again and stir and get final product.
Bicarbonate of ammonia is rolled into big and hard particles through the roll-type tablets press, with said film forming liquid, the film forming matter drying of particle surface is finished product in its surface spraying or roller coating.
Embodiment one:
Get 15 parts of weights of No. 10 petroleum pitch, with its all fusing dehydration, ceasing fire is cooled to 170 ℃ in vessel in heating to 180～200 ℃, adds 40 parts in No. 70 gasoline, and stirring adds 2 part of 200 order light calcium carbonate again, stirs.
Bicarbonate of ammonia is rolled into the particles of heavy 3 grams with multiple roll-type tablets press, the film forming liquid that makes is sprayed on the bicarbonate of ammonia particle surface, make it all coated,, be finished product air stream drying indoor seasoning 1 minute by film forming liquid with shower nozzle.
Claims (4)
1, a kind of coated fertilizer of being made up of core, adventitia is characterized in that the nitrogenous fertilizer core is through the rolling big and hard particles of roll-type tablets press, is that the coating of main film forming matter wraps up in order to pitch.
2, by the coated fertilizer of claim 1, it is characterized in that said nitrogenous fertilizer core is made up of bicarbonate of ammonia.
3, by the coated fertilizer of claim 1, it is characterized in that said film forming matter is by being main film forming matter with pitch, mixes with the mineral filler by solvent with gasoline or dimethylbenzene and is formed.
4, be characterised in that by its manufacturing process of coated fertilizer of claim 1 bicarbonate of ammonia be rolled into big and hard particles through the roll-type tablets press that coating is finished product with the said film forming matter of claim 3 after being dried.
