Description
Technical field
The present invention relates to sericite technical field, more particularly to a kind of bleaching process of sericite.
Background technology
Sericite（Sericite）It is one kind of mica, it belongs to the silicate mineral with layer structure.Sericite
With very extensive purposes, for the row such as rubber, plastics, coating, paint, ceramics, insulation, cosmetics, pigment, papermaking, metallurgy
Industry.
Sericite (Sericite) is a kind of natural particulate muscovite, is the silicate of layer structure, can be split into very thin
Sheet, piece is thick up to below 1um (can be whittled into 0.001um in theory), and radius-thickness ratio is big；Wear resistence and wearability are good；High temperature insulation；
It is insoluble in acid-base solution；Chemical property is stable.The chemical composition of sericite, structure and kaolin are close in addition, have clay again
Some characteristics of mineral, i.e., scattered suspension is good in aqueous medium and organic solvent, and the white grain of color is thin, toughness etc..Therefore, thin,tough silk cloud
Mother has the various features of mica mineral and clay minerals concurrently.
Contain iron oxide inside existing sericite, therefore the color of sericite is not pure, when using sericite, it is necessary to
Sericite to be bleached, existing bleaching is that sericite is reduced by reducing agent, so as to remove internal impurity, bleaching
DeGrain, therefore, the present invention proposes a kind of bleaching process of sericite.
The content of the invention
