Description

一种増效型大量元素水溶肥料防结块剂 Zo macronutrient one kind of water-soluble fertilizer-acting anti-caking agent

技术领域 FIELD

[0001] 本发明涉及一种增效型大量元素水溶肥料防结块剂,属于肥料技术领域。 [0001] The present invention relates to a water-soluble fertilizer macronutrient potentiated anti-caking agent, belonging to the technical field fertilizers.

背景技术 Background technique

[0002] 大量元素水溶肥(Water Soluble Fertilizer,简称WSF),是一种可以完全溶于水的多元复合肥料,它能迅速地溶解于水中,更容易被作物吸收,而且其吸收利用率相对较尚。 [0002] a large number of water-soluble fertilizer elements (Water Soluble Fertilizer, referred to as WSF), a fully water-soluble polyhydric compound fertilizers which can rapidly dissolve in water more readily absorbed by crops, and the absorption efficiency is relatively Yet.

[0003] 目前固体水溶性肥料在生产中存在的突出问题是产品容易出现吸潮结块,尤其是在加工,储运,运输过程中更易出现结块。 [0003] It outstanding problems present in the solid, water soluble fertilizers is the production of products prone to absorb moisture caking, agglomeration occurs more particularly in processing, storage, transport process. 一般含尿素、磷酸二氢钾、硫酸镁(带结晶水)、 螯合微量元素的产品容易吸潮结块。 Generally contain urea, potassium dihydrogen phosphate, magnesium sulfate (with crystal water), chelated trace elements easily absorb moisture caking product. 肥料在加工,储运过程中,由于微观的肥料晶粒发生吸湿,表面溶解(潮解)蒸发,再结晶,在这个过程中形成晶桥,导致小颗粒变成大颗粒而结块。 Fertilizer processing, storage and transportation process, since the occurrence of the fertilizer grain microstructure absorbent surface is melted (deliquescence) evaporation, recrystallization, crystal bridge formation in the process, resulting in small particles agglomerate into large particles. 引起结块的原因是多方面的,主要与原料的吸潮性、含水量(或结晶水)、堆压重量、生产环境的相对湿度、包装材料的吸水性等因素有关,具体为: There are many causes of caking, moisture absorption and the main raw material, a water content (or water of crystallization), the weight of stack pressure, the relative humidity of the production environment, the water-absorbing packaging materials and other factors, in particular:

[0004] 第一,生产肥料通常所用的物料如:铵盐,磷酸盐,微量元素盐,钾盐等,大部分都含结晶水,易吸潮结块,如硫酸铵易结块,磷酸盐与微量元素相遇易结块且变为不易溶于水的物质,尿素遇到微量元素类盐易析出水分而结块,主要是尿素置换出微量元素盐中的结晶水而成为浆糊,然后再结块。 [0004] First, the production of fertilizers commonly used materials, such as: ammonium, phosphate, trace elements salts, potassium salts, most of water of crystallization, hygroscopic caking, easy to agglomerate such as ammonium sulfate, phosphate and trace elements easy to agglomerate and become difficult to meet water-soluble substances, trace elements encountered urea water salt-caking easy to precipitate, mainly urea replacement of trace elements in the salt water of crystallization becomes paste, then caking.

[0005] 第二,肥料生产一般为非密闭生产,在生产过程中,空气湿度越大,肥料越易吸潮结块,天气干燥或烘干原材料,肥料就不易结块。 [0005] Second, the production of fertilizer production is generally non-enclosed, in the production process, the greater the air humidity, the more easily absorb moisture caking fertilizers, weather drying or drying of raw materials, fertilizer caking is not easy.

[0006] 第三,室温越高,利于溶解,一般原料溶解在自身的结晶水中而导致结块。 [0006] Third, the higher the temperature, facilitate dissolution, generally crystalline material was dissolved in water to cause its agglomeration. 氮温度更高时,水分蒸发,又不易结块了,这个温度一般都在50°C以上,我们通常要加热才能达到这个温度。 At higher nitrogen temperature, evaporation, and easy to agglomerate, and the temperature is generally above 50 ° C, we typically heated to reach this temperature.

[0007] 第四,对肥料外加的压力越大,越易于晶体与晶体之间的接触,越易结块;外加压力越小,越不易结块。 [0007] Fourth, the greater the pressure applied to the fertilizer, the easier the contact between the crystal and the crystal, the more easily agglomerate; the smaller the applied pressure, the more difficult to agglomerate.

[0008] 第五,生产出的肥料放置时间越长越易于结块,放置时间越短,越不易结块。 [0008] Fifth, produced fertilizer is placed the longer tend to form lumps, the shorter the standing time, the more difficult to agglomerate.

[0009] 经过多年发展,防结块技术有多种,例如改进产品包装、生产设备工艺、调整肥料剂型、改变肥料组成、改进储存环境以及添加防结块剂等方法,其中添加防结块剂是市场上公认较为简便有效的方法。 [0009] After years of development, there are a variety of anti-blocking techniques, such as improved product packaging, production equipment and technology, fertilizer dosage adjustment, change the composition of the fertilizer, is added to improve the storage environment and method, an anticaking agent, wherein the anticaking agent is added It is recognized as a more simple and effective method on the market. 但是,由于水溶肥料对水不溶物有限量要求,添加在常规复合肥料中的抗结块剂通常不能用于水溶肥料。 However, since a limited amount of water-soluble fertilizer requirements of water-insoluble matter, adding a conventional anti-caking agents generally can not be used FERTILIZER water-soluble fertilizer.
