A kind of for in the Disperse Red, EX-SF DISPERSE BLUE EX-SF 300,63 DISPERSE Violet 63, reactive red, Reactive blue, reactive yellow of described dyestuff.
The preparation method of Shang Shu oxazine humulone granule comprises the steps:
1,, oxazine humulone, binding agent, dyestuff are mixed according to a certain ratio by comminution by gas stream and get
Contain binding agent and the former medicine of dyestuff De oxazine humulone to one.
2, the coating agent is obtained the aqueous solution of coating agent with water dissolution by certain content.
3, take by weighing dressing kernel carrier and place dressing equipment, add in the encapsulation tool earlier a certain amount of
The coating agent solution be mixed together and stir wetting dressing kernel carrier, again by proportioning to encapsulation tool
The former medicine of middle Jia Ru oxazine humulone mixes stirring, makes medicinal powder adhesion uniformly be wrapped in wetting
On the good coating kernel carrier, add remaining coating agent solution in the encapsulation tool again and mix at last
Close and stir.
4, granule that above-mentioned coating is good obtains 0.01-5% after qualified after testing by drying plant
Oxazine humulone combination particle agent product.
Two of technical scheme of the present invention:
Yi Zhong oxazine humulone granule comprises following component by mass percent: oxazine humulone 0.01%～5%, carrier fertilizer 10%～50%, and dispersing auxiliary 0.05%～3%, sustained release dosage 0.01%～2%, binding agent 0.01%～5%, all the other are filler.
Wherein, described carrier fertilizer is one or more the combination in ammonium chloride, ammonium sulfate, urea, Repone K, vitriolate of tartar, the monoammonium phosphate.The N constituent content is 5%～20% of granule gross weight, and the P constituent content is 0～20% of granule gross weight, and the K constituent content is 0～20% of granule gross weight.
