Abstract
The invention discloses a processing method for a micaceous iron oxide. A two-section closed wet type ore grinding operation is adopted, thereby controlling an easily occurring excessive smashing phenomenon of the micaceous iron oxide, promoting yield of the gray micaceous iron oxide, reducing an excessive smashing erubescent phenomenon and increasing economic benefit. Meanwhile, gangue and mud are removed in the optimum size fraction scope after a first-section wet type ore grinding is performed. A present wet superfine grinding device is adopted in a second-section ore grinding process. A frictional force is the main ore grinding way of the wet superfine grinding device, a micaceous iron oxide sheet layer can be excellently split and the content of a micaceous iron oxide laminated structure can be increased. A hydrocyclone set is applied, thereby being capable of achieving large-scale sorting equipment and efficiently reducing power consumption of the sorting equipment. The processing method provided by the invention can be used for reducing the production cost of the micaceous iron oxide, improving a working condition of workers, reducing the pollution to neighboring environment during the production process and promoting use ratio of existing resources.
Description
Technical field
The present invention relates to a kind of micaceous iron oxide processing process.
Background technology
Mica-iron oxide pigment is a kind of flake pigment of stable chemical performance, is mainly used in steel member protective coating.The micaceous iron oxide paint that uses mica-iron oxide pigment to make as raw material is called as armor paint abroad, is widely used on all large-scale steel structures such as railroad bridge, vehicle, iron tower, boats and ships, container, blast furnace stack.Mica-iron oxide pigment is applied in the steel member protective coating; Its protective effect is because pigment flakes tightly packed in paint film; Formed roughly parallel overlapping layer with ground; Thus; Hindered the infiltration of corrosive deposit (like steam and acid, alkali, salt etc.); Reduce ultraviolet ray to coating with lacquer the destruction of base, improved paint film intensity, prevented the generation of defective phenomenons such as paint film adhesion decline, foaming.
In practice; Common and the epoxy resin collocation use of mica-iron oxide pigment; Do the epoxy micaceous iron intermediate coat; Priming paint paints with high-performance weather-proof with zinc rich primer, finish paint, this end, in, the supporting application systems of three kinds in face paint have become the measure that the domestic and international modern large-scale steel structure fabrication of recent two decades (bridge, gate, large-scale pylon and marine building) corrosion-proof coating is taked jointly.Micaceous iron oxide has so big use to we mankind, but micaceous iron oxide is limited.The production cost of micaceous iron oxide is higher all the time, and workman's work under bad environment is more serious to the pollution of surrounding enviroment in process of production.
Summary of the invention
The purpose of this invention is to provide a kind of micaceous iron oxide technological method for processing, adopt the operation of flowing water property, reduced the production cost of micaceous iron oxide, improve workman's working environment, to the pollution of surrounding enviroment, improve the utilization rate of existing resource in the reduction production process.
