Improved lime sulfur and preparation method

Abstract

The invention discloses improved lime sulfur and a preparation method. The improved lime sulfur comprises the following raw materials in parts by weight: 1 part of quick lime, 1.2 to 1.8 parts of sulfur, and 10 to 100 parts of water. The improved lime sulfur can make the sulfur and the quick lime fully reacted, the residue quantity is greatly reduced, and even there is no residue; the concentration of the boiled lime sulfur is high, and the color presents the dark soy sauce color; the concentration of the lime sulfur is remarkably improved, the using effect is good, and the time and labor for residue handling are reduced by means of full reaction between the raw materials, the cost is reduced, and the boiling efficiency is improved. A preliminary experiment is made before formal boiling of the lime sulfur, so that a raw material ratio can be optimized before a great number of raw materials are boiled; moreover, the preliminary experiment is particularly important under the conditions of changing the raw materials, changing a boiling place or changing a boiling pot, thereby effectively reducing the boiling failure rate, and avoiding waste of a great number of raw materials.

Description

Technical field [0001] The invention belongs to the technical field of lime sulfur mixture, and specifically relates to an improved lime sulfur mixture and a preparation method thereof. Background technique [0002] Lime sulfur mixture is made by boiling quicklime, sulfur and water. It is an inorganic sulfur preparation that can kill bacteria, insects and mites. It can prevent and control powdery mildew, rust, brown rot, brown spot and black star. Diseases, spider mites, scale insects and other pests and diseases. [0003] After long-term practice, it was found in the actual preparation process that sulfur itself is insoluble in water. After boiling, part of the sulfur often does not fully react with quicklime, forming a yellow sediment, resulting in a waste of sulfur in the material. Moreover, due to different manufacturers of raw materials, different storage times, and different cooking places, the existing cooking formulas cannot be universally used. Moreover, due to var...

Problems solved by technology

[0003] After long-term practice, it was found in the actual preparation process that sulfur itself is insoluble in water. After boiling, part of the sulfur often does not fully react with quicklime, forming yellow sediment, which causes waste of sulfur on materials.

Moreover, due to different manufacturers of raw materials, different storage times, and different cooking places, the existing cooking formulas cannot be universally used, and due to various reasons, the cooking conditions vary greatly, so that stone sulfur boiled with general parameters Most of the mixtures have low concentration, poor effect and serious waste of raw materials

At the same time, because the raw materials and cooking parameters cannot be well controlled, the quality of many self-boiled lime sulfur mixtures is unstable.

In the prior art, there is also a method of adding washing powder in order to promote the dispersion of sulfur, but as we all know, washing powder is harmful to plants, and washing powder will produce foam, so that there is a large amount of water on the liquid surface during the boiling of lime sulfur mixture. Foam gathers, it is difficult to observe the color of the lime sulfur mixture, and many existing washing powders contain substances such as sodium tripolyphosphate, which is difficult for consumers to distinguish, so that during the boiling process of the lime sulfur mixture, it is mixed with the calcium in the boiled liquid. The ions react to form complexes, resulting in a reduction in the generation of polysulfide calcium, reducing the concentration of lime sulfur
