Functional redware pottery and its preparation method

Abstract

This invention involves a functional purple-sand pottery and preparation methods. According to weight its use following raw materials: 70-90% purple-sand, diatomite 2.5-7%, CaCO3 2.5-5%, shell power 3-8 %, 2-10% tourmaline; first smash and grind the purple sand, mixed as slurry, then use post-treat methods to coat the slurry on the surface of pottery about 0.5 to 1.5mm, naturally dry, 800 ~ 950 deg sintering. The water treated by functional purple-sand pottery has changed molecules more small; about pH 7.4, is weakly alkaline water; remove harmful substances; function purple-sand pottery can change the molecular structure of water and energy resonance characteristics. The activated and shaped drinking water has special biological effects that can pass through the cell to send information, enhance biological dynamic.

Description

technical field [0001] The invention relates to a functional purple sand pottery and a preparation method thereof, in particular to a functional post-finishing method of the purple sand pottery for restoring the physical structure of water and activating water quality. technical background [0002] Purple sand is a kind of silicate mineral. Purple sand is produced in Yixing, China. It is mainly composed of quartz silt and clay minerals glued to it. Quartz debris is distributed in isolation in the glue structure. Under the microscope, the purple sand clusters can be observed. Chain pores, as well as fine pores inside the aggregate, purple sand is different from ordinary pottery clay, and purple sand has a double pore structure. The double pore structure makes the product have high pore density and certain porosity (the porosity of Yixing purple clay reaches 20.9% after drying). Zisha ore contains MnO, CrO 3 , CoO, CuO, PbO and other elements; Zisha pottery has a production ...

AI Technical Summary

Problems solved by technology

Tourmaline crystals can produce electrodes due to piezoelectricity and pyroelectricity, which have an important impact on the physical structure of water and activate water quality, but when the firing temperature is higher than 950 ° C, the crystal structure will be destroyed and its function and effect will be lost.

In some methods, it is advocated to add tourmaline powder to the purple sand for material blending and modification to make purple sand pottery, but the "physical characteristics" and physical and chemical indicators of purple sand pottery cannot be realized at a firing temperature of 950°C, so it cannot be called Finished purple sand pottery (there are national standards for purple sand pottery)

In some methods, the particle size of tourmaline added to the mixed material cannot be less than D 50 : 300nm fineness, trying to achieve the purpose of optimizing water quality by increasing the proportion of tourmaline powder, but this method reduces the proportion of purple sand in purple sand pottery, which also affects the technical requirements and unique artistic appreciation of purple sand pottery
