Process for producing diatom mud

Abstract

The invention discloses a process for producing diatom mud; with diatomite as a raw material, the process comprises the following process steps: a, an air flow crushing step: putting diatomite to a crushing tank, introducing high-pressure gas, crushing, and allowing the particle size to reach 2300-2700 mesh; b, a screening step: putting the diatomite crushed in the step a into a conical reaction kettle, adopting a free falling way, collecting the diatomite after the diatomite falls for 70 s; c, an additive premix step: mixing an inorganic toner, food cellulose, inorganic glue and white sand; and d, a negative ion stirring step: putting the diatomite screened in the step b into a negative ion stirring device, adding the additive mixed in the step c during the diatomite stirring process, and mixing the diatomite with the additive to form the diatom mud. The process has the beneficial effects that the diatomite is prepared by adopting the physical method, and has the advantages of no generation of pollution, environmental protection, energy conservation, pure color, low oxidation rate and high stability.

Description

technical field [0001] The invention relates to a production process of wall materials, in particular to a production process of diatom mud. Background technique [0002] Diatom mud is a kind of interior decoration wall material with diatomite as the main raw material. It has the functions of eliminating formaldehyde, purifying air, adjusting humidity, releasing negative oxygen ions, and fire and flame retardant. Diatoms are living in millions of years A single-celled aquatic plankton in the past, after diatoms die, it will deposit on the bottom of the water, and after hundreds of millions of years of accumulation and geological changes, it will become diatomite. Because diatom mud is healthy and environmentally friendly, it is not only very decorative, It is also functional and is a new generation of decorative materials to replace wallpaper and latex paint. However, in the production process of the existing diatom mud, because the diatom earth is crushed by ball milling, i...

[0002] Diatom mud is a kind of interior decoration wall material with diatomite as the main raw material. It has the functions of eliminating formaldehyde, purifying air, adjusting humidity, releasing negative oxygen ions, and fire and flame retardant. Diatoms are living in millions of years A single-celled aquatic plankton in the past, after diatoms die, it will deposit on the bottom of the water, and after hundreds of millions of years of accumulation and geological changes, it will become diatomite. Because diatom mud is healthy and environmentally friendly, it is not only very decorative, It is also functional and is a new generation of decorative materials to replace wallpaper and latex paint. However, in the production process of the existing diatom mud, because the diatom earth is crushed by ball milling, it is easy to blacken during use and form The quality of the wall material is poor, the surface is not smooth, it is easy to fade, and the ability to purify the air is poor
