Abstract
The invention relates to a potassium chloride wetting agent and a preparation method thereof. The potassium chloride wetting agent comprises, by mass, 30-45% of a anionic surfactant, 5-10% of a nonionic surfactant, 15-30% of a humectant and 30-40% of water with low hardness. The preparation method comprises: dissolving the anionic surfactant in water until the solution is uniform to obtain a solution 1; adding the nonionic surfactant to the solution 1, followed by carrying out stirring until the nonionic surfactant is dispersed completely to obtain a solution 2; cooling the solution 2 to a room temperature, followed by adding the humectant to the solution 2 and uniformly mixing to obtain the potassium chloride wetting agent. Advantages of the potassium chloride wetting agent are as follows: the wetting agent is liquid at a room temperature and is a full water-soluble agent; the wetting agent is easy to be used, and can be used through directly adding water without heating; the use amount of the wetting agent is small, wherein wetting of one ton of potassium chloride only requires 1-3 kg of the wetting agent; the wetting agent is applicable for the potassium chloride in a flotation process so as to effectively improve wettability and solubility of the potassium chloride. In addition, the potassium chloride wetting agent is applicable for a fertilizer, and satisfies a requirement of rapid dissolution of the fertilizer.
Description
Technical field
The present invention relates to a kind of Repone K wetting agent and preparation method thereof.
Background technology
Repone K is white crystals or crystalline powder, self is soluble in water, is the quick-acting potash fertilizer of high density, is the principal item of potash fertilizer, account for 95% of potash fertilizer total amount, other potash fertilizer such as vitriolate of tartar, saltpetre, salt of wormwood etc. all are to be that main raw material is produced and obtained with Repone K.Therefore the production of Repone K directly influences the production of other potash fertilizer.
For many years, China relies on import potash fertilizer to alleviate or interior demand, and China exists the potassium resource demand big, reserves are few, and the rate of recovery is low, waste present situations such as serious, the Repone K production technique that chooses is utilized potassium resource to greatest extent, is significant.
For better, utilize potassium resource to greatest extent, people adopt floatation process mostly, use some flotation reagents, flotation reagent all is that tensio-active agent is formed mostly, and the hydrophilic group of tensio-active agent is connected on the sylvite, outside oleophilic group is exposed to, can residually there be butyrous flotation agent material on the Repone K top layer that causes like this obtaining after flotation, influences the wetting and solubility property of Repone K.Because Repone K itself more easily lumps, some Repone K producers can adopt mineral oil or liquid anti-caking agent (being made up of a large amount of tensio-active agents) to wrap up, reach the anti-caking purpose with this, thus, just make the Repone K remained on surface that more hydrophobic grouping is arranged, it is wetting that Repone K is difficult to more, and solvability is poorer, have a strong impact on directly using of Repone K as potash fertilizer, and cycling processability:
1, Repone K is one of main raw material of composite fertilizer as the main provider of potassium nutrition in the composite fertilizer.But in production composite fertilizer process, because the wettability of Repone K is poor, make be difficult in the production process of compound compound fertilizer wetting, mix at fertilizer material, occur a large amount of dry powder Repone K in the granulation process, have a strong impact on compound compound fertilizer pelletizing, often need repeatedly returning charge, just can make Repone K raw material complete wetting, have a strong impact on the production of composite fertilizer.
2, along with the development of fertilizer industry, dash the another megatrend that fertilising progressively becomes fertilizer industry.Dash the fertilising industry standard, require dissolving fast, water-insoluble requires to be lower than 0.1%, and the dissolving back water surface does not allow floating oil.Therefore the process floatation process is produced, or can't satisfy the requirement of making towards the fertilising raw material through the Repone K that anti-caking agent (oily or the agent of liquid anti-caking) is handled.
The wetting poorly soluble problem of Repone K has had a strong impact on directly using of Repone K, and cycling processability, brings massive losses for Repone K industry and association area thereof.Therefore developing a kind of wetting deliquescent product of Repone K (wetting agent) that improves becomes the task of top priority.
Summary of the invention
The objective of the invention is to solve Repone K that the Repone K produced because of flotation and anti-caking handle and have wettability, poorly soluble phenomenon, thereby have a strong impact on Repone K and be difficult to directly to use problem with cycling processability, and provide a kind of Repone K wetting agent and preparation method thereof, Repone K wetting agent normal temperature provided by the invention is liquid, good fluidity, consumption is little, generally speaking, one ton of Repone K of complete wetting only needs wetting agent 1-3 kilogram.Need not heating can directly add in the fertilizer slurry, simple to operate, wetting agent is mixed with the aqueous solution that mass concentration is 0.1%-0.3%, with indissoluble separate, the Repone K of wettability difference drops into wetting agent solution wherein, just can moisten fast and dissolve, even if prepare towards applying fertilizer with the sort of insoluble Repone K, only need be when fertilising solution be dashed in preparation, add minute quantity wetting agent of the present invention, just can make and dash fertilising and dissolve fully fast, and floating oil not.Satisfy the service requirements of dashing this high-end fertilizer of fertilising fully.
For achieving the above object, technical scheme of the present invention is:
A kind of Repone K wetting agent is made up of following each component, and each component by mass percentage, it is characterized in that: anion surfactant 30-45%, nonionogenic tenside 5-10%, wetting Agent for Printing Inks 15-30%, low-hardness water 30-40%, each component sum is 100%.
The preparation method of described Repone K wetting agent is characterized in that: carry out according to the following steps:
(1) anion surfactant is dissolved in low-hardness water, can be hot a little in the time of necessary, temperature is controlled at below 60 degree, accelerates the dissolution rate of tensio-active agent, promptly obtains solution 1 until the even one of solution;
(2) nonionogenic tenside is joined dissolve fully in the uniform solution 1, be stirred to fully and disperse, promptly obtain solution 2;
(3) treat that solution 2 is cooled to room temperature, in solution 2, add wetting Agent for Printing Inks, stir and promptly obtain the Repone K wetting agent.
Described anion surfactant is that the sodium alkyl sulfate of sodium soap, C12 of C12-C14 is or/and the sodium alkyl benzene sulfonate of C12.
Described nonionogenic tenside is polysorbas20, polysorbate40 or polysorbate60.
