Embodiment Construction

[0013] The raw materials for preparing the diatomite adsorption slow-release control functional material are as follows: 55-65 kg of 500-mesh diatomite powder; 0.5-1.5 kg of 1250-mesh tourmaline powder or nano titanium dioxide; 38-42 kg of 325-mesh attapulgite powder.

[0014] See figure 1 , the production method is as follows: First, the above-mentioned 500-mesh diatomite powder and a quarter of the 325-mesh attapulgite powder are stirred and mixed, and rolled into a spherical shape by a granulator. The granulation adopts the existing process, that is, rolling granulation Spray a mist liquid adhesive (aqueous solution containing 0.05% CMC); coat the remaining three-quarters of the attapulgite powder on the spherical surface for the first time, and at the same time coat 1250 mesh tourmaline powder or nano-titanium dioxide for the second time; then Drying is carried out by drying equipment at a drying temperature of 100° C. for 2 hours; finally, roasting is carried out by ...

Abstract

The invention discloses a kieselguhr adsorption sustained-release functional material, which is characterized by comprising the following raw materials in part by weight: 55 to 65 parts of kieselguhr powder, 0.5 to 1.5 parts of tourmaline powder or nano titanium dioxide, and 38 to 42 parts of attapulgite powder. The functional material can realize human regulation of adsorption and release, and meanwhile, the functional material is loaded; and the method can realize disposable material formation (ball formation), namely simultaneously finishing four functions of sustained-release control, functional material load, compensation adsorption and improvement on mechanical strength.

Description

technical field [0001] The invention belongs to a diatomite composite material, in particular to a diatomite adsorption slow-release control functional material and a production method. Background technique [0002] Diatomaceous earth is the new material with the most ecological and environmental protection characteristics in the 21st century. It is known as the "submarine grassland that breeds life". It is an emerging industry with important strategic significance that the country is competing to develop. Entering the new century, the high-tech and new material industries centered on information, biology, aerospace, marine development, and new materials and new energy are developing and growing. Traditional industries such as energy, chemical industry, machinery, metallurgy, light industry, and building materials are in urgent need of The introduction of new technologies and the use of new materials, technological innovation and industrial upgrading, the protection of the ...
