Abstract

The present invention is one kind of composite red sand material and its preparation. The composite red sand material capable of being sintered at temperature as low as 950 deg.c consists of red sand 50-85 wt%, feldspar 1.5-5 wt%, calcium carbonate 2.5-5 wt%, active carbon 1-10 wt%, and tourmaline 10-30 wt%. The preparation process includes the steps of: crushing and grinding, mixing to form slurry, drying, sintering, crushing, forming and secondary sintering. The composite red sand material may be used in treating water to make water smaller in molecular group, pH value in about 7.4 or weak alkalinity, lower in oxidation and reduction potential and harmful impurity eliminated; has special biological effects of transmitting information via cells, etc. and can improve quality of water for human body, animal and crop.

Description

technical field [0001] The invention relates to a composite purple sand material and a preparation method, belonging to the field of silicates. technical background [0002] Purple sand is a kind of silicate mineral. The type of purple sand is silty mudstone. It is a silty muddy structure with more iron content. It is mainly produced in Yixing, China. It is named iron-bearing clayey siltstone. The rock is mainly composed of quartz silt and clay minerals that glue it, and the quartz debris is distributed in the glue structure in isolation, forming a basal cementation. Under the microscope, you can observe the chain pores between the purple sand aggregates, the single minerals such as quartz and clay and the aggregates, and the tiny pores inside the aggregates. The purple sand is different from ordinary clay. The ordinary clay has a single crystal structure, and the purple sand has double pores. structure. The double pore structure makes the product have high pore density an...
