Description
Technical field
The present invention relates to a kind of tinting material, especially a kind of intrinsic color agent that is specifically designed to compound diammonium hydrogen phosphate fertilizer.
Background technology
There is the good reputation of " king of chemical fertilizer " in diammonium phosphate (DAP) composite fertilizer.But since adopt different phosphorus ore raw materials with different in and the granulation reactor, the particle color of institute's output changes in white, grey, beige, between light blue, diammonium phosphate (DAP) compound fertilizer granules outward appearance is beautiful in order to make, color even or be the product of different brands mark look, need its particle be transformed into coloured appearances such as coffee color, golden yellow, green, blueness by tinting material, so that achieve the above object.Painted and the anti-caking of diammonium phosphate (DAP) composite fertilizer separates often, carries out the inside painted (being referred to as intrinsic color) of product earlier, after surface treatment (being referred to as anti-caking) such as wrap up.Tinting material commonly used mainly is made up of mineral dye (as carbon black, iron oxide black, iron oxide yellow, red iron oxide etc.), pigment dyestuff (as acid scarlet, erie black, Sodium salts humic acids, indigo etc.) and dispersion agent (as Sodium hexametaphosphate 99, trisodium phosphate etc.).Diammonium phosphate (DAP) composite fertilizer divides two kinds of traditional method and slurry process by the difference of its production method, and the fertilising custom based on long-term formation adopts coffee-like intrinsic color agent more.
DAP intrinsic color agent commonly used is owing to used the mineral dye red iron oxide too much, since its with pre-neutralization after acid slime in the phosphoric acid back generation phosphoric acid salt complex compound that reacts, water-soluble P205 is degenerated to arrests dissolubility P205, red iron oxide as red matrix was lost efficacy, cause in secondary and granulation, drying and screening after the DAP particle color and luster of acquisition dismal, smooth finish and mellow and full degree are poor, need just can obtain qualified coffee-like DAP particle by the secondary extrinsic color.Not only tinting material consumes height, and complex procedures, and tooling cost is up to 80 yuan/t product.Therefore, the special-purpose intrinsic color agent of DAP composite fertilizer that need seek a kind of efficient economy of suitable acid slime condition addresses the above problem, and will help to improve the DAP quality product, strengthens its market competitiveness.
Summary of the invention
For solving above technical problem, one of purpose of the present invention is to provide a kind of coloring effect good, the special coloring agent of diammonium phosphate compound fertilizer that manufacturing cost is low;
Two of the object of the invention is to provide a kind of preparation method of special coloring agent of diammonium phosphate compound fertilizer.
A kind of special coloring agent of diammonium phosphate compound fertilizer, this tinting material comprises following component by ratio of weight and the number of copies:
40～50 parts of humates
0.1～3 part of carbon black
Acid black 2～4 part
1～2 part of acid scarlet
0.2～1 part of Sodium hexametaphosphate 99
40～56.7 parts in water
The preparation method of special coloring agent of diammonium phosphate compound fertilizer, prepare earlier material by weight, water is joined in the reactive tank, add humate, carbon black, erie black, acid scarlet again, after stirring, add Sodium hexametaphosphate 99, continue to stir, the last preparation that stirs obtains special coloring agent of diammonium phosphate compound fertilizer.Erie black also makes acidity deceive greatly in the industry or chromium closes acidproof big deceiving,
All mix in the vertical circular reactive tank in the belt stirrer turn on agitator at water described in the mixing process, humate, carbon black, erie black, acid scarlet and Sodium hexametaphosphate 99, this agitator speed is 400～600r/min, wherein add humate, carbon black, erie black and acid scarlet and in water, stir 20～30min, restir 60～90min behind the continuation adding Sodium hexametaphosphate 99.
The present invention is from solving the production adaptability and the applying environment pollution problem angle of tinting material, humate preferred cheap and easy to get and the acid big black black matix of doing, acid scarlet is red matrix, and add a certain amount of inorganic salts sodium hexametaphosphate dispersant, made diammonium phosphate (DAP) the composite fertilizer special coloring agent of coffee colour system by high-speed stirring.The black matix humate itself that the present invention selects for use is the required organic matter of a kind of crop growth, and the effect of fixed nitrogen synergic is arranged, and is a kind of good soil improvement agent, fertilizer synergistic agent, crop growth stimulant; The sodium hexametaphosphate dispersant itself that adds can be used as fertilizer for the crop absorption utilization, not only can dispersion staining matrix, strengthen color consistency, stability and coloring effect, and can also disperse diammonium phosphate (DAP) particulate, alleviate caking phenomenon; Replace traditional red iron oxide to make red matrix with acid scarlet, avoided phosphoric acid salt complex compound generation in the acid slime effectively, arrest dissolubility P205, strengthen the coloring effect of red matrix thereby avoid water-soluble P205 to be degenerated to; In addition, the particle dispersiveness and the sticking power of intrinsic color agent are strengthened greatly, easily fade and the color and luster problem of unstable thereby solved diammonium phosphate (DAP) tinting material by adopting superfine grinding and high-speed stirring technology.
Range of application of the present invention, working conditions, use are as follows:
1, scope should be arranged: be limited to traditional method diammonium phosphate and slurry process diammonium phosphate.
2, working conditions: traditional method diammonium phosphate and slurry process features of DAP production device for all size all can use, and product is not had temperature requirement, and the product water content requires to be less than or equal to 2.5%, and product must be a particulate state.
3, use: the ratio of this kind intrinsic color agent in 5/1000ths to 10/1000ths (being generally 7/1000ths to 8/1000ths) of diammonium phosphate (DAP) output directly joined in the acid slime of production technique, can reach the intrinsic color purpose.
Under these conditions, testing program of the present utility model is: add intrinsic color agent of the present invention in the acid slime of diammonium phosphate (DAP), is that the intrinsic color agent is compared by it with add mineral-type pigment red iron oxide commonly used in the acid slime of diammonium phosphate (DAP), and the experimentation record is as follows:
| Sequence number | Time | Acid slime flow/m 3h -1 | Red iron oxide commonly used is the intrinsic color agent | Intrinsic color agent of the present invention | Coloring effect | Tinting material unit consumption/kgt -1DAP (wet basis) | Remarks |
| ??1 | ??8:00 | ??24.8 | ??320 | Relatively poor | ??8.17 | Brownish black | |
| ??2 | ??9:00 | ??24.7 | ??320 | Better | ??8.20 | Dark brown | |
| ??3 | ??10:00 | ??23.7 | ??280 | Fabulous | ??7.48 | Coffee-like | |
| ??4 | ??11:00 | ??23.9 | ??280 | Good | ??7.41 | Coffee-like | |
| ??5 | ??13:00 | ??23.3 | ??260 | Good | ??7.06 | Coffee-like | |
| ??6 | ??14:00 | ??23.6 | ??240 | Better | ??6.44 | Light coffee color | |
