A kind of active nano-scale single crystal silicon dioxide

Abstract

The invention relates to active nanoscale monocrystal silicon dioxide, which is characterized by being processed as follows: (1), roughly screening ore: washing, acid-pickling and neutralizing till the PH value is 4-10 in the aqueous environment to remove impurity monocrystal on the surface of ore, and roughly crushing; (2), dryly crushing at the linear speed of 6-25 m / s and the air pressure of 2-18 kg; (3), processing through the monocrystal grading process, wherein a dry type grading monocrystal fine-grinding process is adopted; (4), crushing through a wet method: carrying out dispersed processing and nanoscale grinding in the neutral aqueous environment in the event of not destroying the monocrystal morphology to realize final fineness processing of granules so that the nanoscale is up to 10-800 nm and the specific surface area is maximized so as to achieve forming and processing of nanoscale granules with the easy dispersion effect, and finally processing and polishing granule shapes, so that the surface activity is higher, and rubber binding and forming are facilitated; (5), carrying out nano-surface processing: carrying out nano-activity processing to process liquid into powder.

Description

technical field [0001] The invention relates to an active nanometer single crystal silicon dioxide. Background technique [0002] The existing similar products are white carbon black produced by gas phase method or white carbon black produced by precipitation method. Since white carbon black is a thixotropic substance, the amount added to rubber products is limited and it is not easy to disperse. , which affects the production efficiency of rubber, restricts the production efficiency of rubber, and increases the energy consumption in the rubber production process. Because the amount of addition is limited, the improvement properties as a filler in the rubber main material cannot be fully exerted. The true nano-characteristics of nano-scale silicon dioxide cannot be reflected at all. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides an active nanoscale single crystal silicon dioxide. [0004] In order to achieve the ab...
