Nutrition type water retention ball and method for manufacturing the same

Abstract

The invention discloses a nutrimental water-saving polo and the preparing method, the said water-saving polo concludes kernel and shell, the said kernel is water-saving material, the shell is the nutrimental organic-inorganic complex, and the kernel is covered by the shell. The strong compressive resistance characterizes the said water-saving polo, the durability of transportation, rapid water intake rate, good expansion pressure, the 50-150% increase of the repeatable water intake, simple manufacturing technique and advanced method.

Description

【Technical field】 [0001] The invention relates to a nutritional water-retaining agent and a manufacturing method thereof. 【Background technique】 [0002] At present, there are many kinds of superabsorbent materials produced in the world, and there are mainly four types: one is the total synthesis type based on organic monomers such as acrylic acid and acrylamide; the other is the cellulose graft modified type based on cellulose. The third is the starch graft modified type with starch as raw material; the fourth is the natural type with natural minerals such as vermiculite, montmorillonite, sepiolite, etc. as raw materials. Before the mid-1990s in China, there were more than 40 kinds of water-retaining agents, but due to: 1. Due to technical problems, the product has a bad appearance and unstable quality, and some of them are less effective after being applied to the soil. Second, without considering the characteristics of agricultural applications, especially the lack of th...

Problems solved by technology

Before the mid-1990s in China, there were more than 40 kinds of water-retaining agents, but due to: 1. Due to technical problems, the product has a bad appearance and unstable quality, and some of them are less effective after being applied to the soil. Second, without considering the characteristics of agricultural applications, especially the lack of the most basic understanding of soil, fertilizer, water, and seed knowledge, the effect and performance of water-retaining agents directly applied to agricultural production are unstable. For example, after being applied to the soil, The water absorption ratio is reduced by 2 / 3; 3. Due to the influence of raw materials and production process efficiency, the product price is high, and the cost per mu is as high as 120-180 yuan and many other reasons, so that the demonstration and application of water-retaining agents in agricultural production have been in a state of hesitation.

After the mid-1990s, the development of water-retaining agents began a new round of climax, but in general, the industrialization of agricultural water-retaining agents is quite difficult: one is to use organic monomers such as acrylic acid, acrylamide, etc. The water-retaining agent products of raw materials have high production costs, and the price of agricultural and forestry products is high, which is difficult for farmers to accept; secondly, from the perspective of chemistry, physics and biology, water-retaining agents are high-tech products, but for composite water-retaining agents, new There is a lack of necessary research and development in the technical formula, production process and technical standardization of drought-resistant agents; third, the existing water-retaining agent products are highly technical when applied in actual production, and certain training and guidance are required to master the use methods Work

Moreover, most of the water-retaining agents currently produced are in the form of powder, flake, fiber, and liquid, and are widely used in powder form, which is very inconvenient to apply.
