A kind of nanometer bamboo charcoal powder production process

Abstract

A production process for nanometer bamboo charcoal powder mainly comprises four stages, namely rough treatment of materials, ultrafine processing, nanometer material production and nanometer material subsequent treatment. The stage of rough treatment of the materials includes the steps that bamboo charcoal is selected firstly; then the processes of alkali washing, acid pickling, water washing, solvent digestion and drying are sequentially conducted; afterwards, raw powder is roughly crushed under gas protection; and finally powder with the fineness being 1-5 mm is subjected to fine crushing. The stage of ultrafine processing includes the step that the materials of 30-100 [mu]m are crushed into ultrafine materials of 1-10 [mu]m. The stage of nanometer material production includes the steps that the ultrafine materials of 1-10 [mu]m are crushed again through a dry-method nanometer impact grinder, the fineness of the crushed materials is 200-1000 nanometers, and the powder is passivated when the dry-method nanometer impact grinder conducts crushing. The stage of nanometer material subsequent treatment includes the step that the materials are accelerated through supersonic-speed airflow, nanometer powder aggregate is opened, and the materials are fluidized.

Description

technical field [0001] The invention belongs to the technical field of bamboo charcoal product processing, and in particular relates to a production process of nanometer bamboo charcoal powder. Background technique [0002] The application of bamboo charcoal resources has been greatly developed in recent years, and various treated functional bamboo charcoal products have emerged as the times require; technical solutions for ultrafine grinding of bamboo charcoal have also appeared. For example, Chinese Invention Patent Publication No. CN1590051A discloses a processing method of bamboo charcoal superfine powder and a technical scheme for its application in synthetic fibers; This ultra-fine pulverization method needs to consume a large amount of water owing to adopting wet ball milling and centrifugal sedimentation method, can cause a series of post-processing procedures such as waste water treatment, slurry drying; block; therefore, the process of the method is complicated an...
