Description

Anti-compaction growth promotion spacetabs type compound fertilizer and preparation method thereof
Technical field
The invention belongs to or various fertilizer and the mixture field without special fertilizer efficiency component, specifically anti-compaction growth promotion delays Release compound fertilizer and preparation method thereof.
Background technology
Slow-release compound fertilizer nutrient content is high, accessory ingredient is few, both can improve utilization rate of fertilizer with balance fertilizing, again can be with It is made for that thing is lasting to be absorbed, the stable high yield to promoting crop has highly important effect, has become current chemical fertilizer The Main way of development.In fertilizer production the enterprise especially daily production of granular complex fertilizer manufacturing enterprise and storage process In, it is particularly nitrogenous because the hardened phenomenon of fertilizer is very universal caused by interaction between chemical fertilizer granule crystal combination key The amount hardened phenomenon of chemical fertilizer high is especially serious.The hardened inconvenience for causing to carry and use of fertilizer, causes sales difficulty and stock Overstock.
Data show, the substandard product caused by fertilizer is hardened has millions of tons every year.Particle compound is reduced at present The hardened measure of fertilizer in addition to temperature, humidity are controlled in transporting procedures, the approach such as storage pressure are grasped, main method be Anticaking agent is used during generation, it is the coated media that can be attached on particle surface.Powdered anti-caking agent is mostly inactive Thing inert powder, such as diatomite, clay, talcum, also have using oyster shell whiting for raw material is obtained(Such as Authorization Notice No.: It is CN103553776B, entitled《Granular fertilizer anticaking agent and preparation method thereof》Chinese invention patent).Liquid person lives for non-surface The organic compound of property, for example, be sprayed on oil product, paraffin, resin of particle surface etc., or special surfactant(Example Such as Authorization Notice No.:It is CN101654387B, entitled《Liquid anti-caking agent for compound fertilizer》Chinese invention patent).
Above method by checking, it is hardened to fertilizer it is equal can play certain mitigation, but long term storage(2 months More than)There occurs universal hardened phenomenon.Therefore more permanent effective anticaking agent is found, with reference to production technology and addition manner Improvement effectively prevent the hardened purpose of fertilizer to reach, be urgent problem of the pendulum in face of compounded fertilizer of granulated enterprise at present, It is the problem of present invention needs solution.
