Description
Fertilizer preventing blocking technology field under the present invention relates to the moistureproof anti-hard caking agent of mineral manure.Main outer coated coating agent and interior interpolation anti-hard caking agent as restriction compound fertilizer from caking and efflorescence trend.This fluffy powder is made up of water repellent agent, anti-looseness agent and antiblocking agent etc.
Development day by day along with chemical fertilizer industry, composite fertilizer is because the fertilizer efficiency diversification, the fertilizer efficiency height, moderate, production technique and facility investment are less, so high dense multi-component composite fertilizer begins that in mid-term new millennium develop rapidly has been arranged, but because the raw material of composite fertilizer, ammonium nitrate for example, urea, saltpetre, ammonium hydrogen phosphate, vitriolate of tartar and Repone K etc., water absorbability is in various degree all arranged, make composite fertilizer in production process and in storage period, there is easy moisture absorption caking, particle adhesion, easily efflorescence, the high defective of technological process returning charge rate, thereby high dense composite fertilizer is stored and difficult treatment.
Since 20th century the seventies, proposed some solutions already and limited the method for above-mentioned technical problem: the technology of ancient classics, be on 40 ℃ of warm composite fertilizer surfaces, in the face powder machine before the packing post, spray the lubricated cladding of powderies such as talcum powder, terra alba material, to prevent compound fertilizer from caking.But this type of face powder exists moistureproof preventing blocking effect bad, and serious environment pollution; The nineties, external many scholars that are engaged in compound fertilizer anticaking agent research, applied for patent of invention in China, France scholar L. nanowatt Si Kusi (Chinese patent 95118864,1996) point out: adopt the melts of oil, wax class to handle composite fertilizer, improve composite fertilizer's agglomeration preventing performance, but this material exists the thermoplasticity scope little, make the granule strength of composite fertilizer too low, the atomizing defective is not resolved yet.
Modern age, Finland T. A Ennasi (Chinese patent 96 198625.5,1998) find: in mineral oil, fuse into the dibasic amino acid salt that generates by cationic amine such as aliphatic amide, polyamine and anionic carboxylic acid, think that this dispersion system forms the low viscosity compounded oil, by spraying tiny drop, make its cladding on the composite fertilizer surface, can obtain best moistureproof preventing blocking effect.But obtain above-mentioned dibasic amino acid salt, carboxylic acid must be dissolved in the methanol solvate, amine will dissolve in the ether, could get above-mentioned carboxylate salt again under certain technological temperature, think thus the production cost height, produce and use inconvenience, a large amount of solvents of employing dangerous again.Japan storehouse Tian Dusan (JP7650896,1978) thinks: directly can use 0.01%～0.1% the main anti-hard caking agent of amides conduct, but this class material price is very expensive.Water-soluble " flower king " fertilizer additive by Spain's invention is milkiness thickness state, and packing, transportation and use are all inconvenient.In addition, the method that the anti-caking of the composite fertilizer of inventing till settled the present, anti-efflorescence are handled, almost all adopt external parcel oil tech to fertiliser granulates, exist facility investment big, account for the place, need with drawbacks such as mineral oil, cost height, thereby abovely handling composite fertilizer preventing blocking technology field both at home and abroad, exist at aspects such as the performance of additive, commercial viability, economy, Technology approach and be badly in need of the technical barrier that solves.
