Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stirring devices, in particular to a stirring device for a coconut bran-based water-retaining agent used in a chemical laboratory. Background Art
[0002] Super absorbent resin (also known as water retainer) is a high molecular polymer with a three-dimensional network structure formed by cross-linking hydrophilic monomers (mainly acrylic monomers). The three-dimensional network formed during polymerization can wrap specific guest molecules to form a complex. The characteristic of water retainer is that it swells in water to form a gel. The swollen gel will have an inhibitory effect on the dissolution and diffusion of the wrapped or bound guest molecules, thereby reducing their release rate, so that the prepared product has both certain water absorption, water retention, and moisture retention properties, as well as certain slow release properties. Studies have shown that acrylic materials and their derivatives can present different rigidity, hardness and viscosity when polymerized, and are an important class of slow / controlled release materials. Traditional water retainers are limited in their large-scale promotion and use due to their high cost and single function. Introducing cheap natural polymers into the production raw materials and wrapping cheap fertilizers in the network can give them the function of slow-release fertilizers while reducing product costs. The introduction of foaming agents can form a controllable pore structure, increase the amount of three-dimensional networks, and control the speed of slow release by adjusting the number of pores and the size of the pores.
[0003] Coconut bran is the most commonly used culture medium for soilless cultivation. It is organic, pathogen-free, and chemically additive-free, and meets environmental protection requirements. The main components are cellulose and lignin, which are rich in hydroxyl groups and can participate in grafting polymerization to generate a three-dimensional network structure. Coconut bran has a weak water retention capacity and is prone to water accumulation, leading to root rot of crops. By grafting polyacrylic acid with coconut bran to generate a macroporous three-dimensional network structure, the water absorption and water retention capacity of the matrix is increased, which can solve the problem of root rot of crops and reduce the construction cost of soilless cultivation.
[0004] In the process of preparing coconut bran-based water-retaining agent, the solid particles and the liquid solvent are mixed by stirring. Most of the existing stirring devices for this purpose are tank structures, which are not convenient for taking out the container and the material when conducting a small number of experiments.
