Description

Preparation method of active porcelain

Technical Field

The invention belongs to the field of porcelain preparation, and particularly relates to a preparation method of an active porcelain.

Background

China is the home country of porcelain, and porcelain is an important creation of ancient workers; the invention of porcelain is a great contribution of Chinese nationality to world civilization; the original porcelain is a material sintered by kaolin, and the manufactured ware is finer and harder than the pottery; generally as containers, for the storage and packaging of substances; with the continuous improvement of mental life and physical life of people, people no longer meet the packaging function of porcelain wares; the exquisite appearance and the healthy use become the targets of people to pursue continuously nowadays.

Ru porcelain is the first of five famous porcelain, and the traditional Ru porcelain is mainly prepared by adding quartz, black feldspar, yellow feldspar, high collar soil (Fengcave soil and half slope soil), clay (black hair soil and Tanggou soil), calcite, dolomite, plant ash and the like; when adding, the method mainly comprises the following steps of: processing the raw materials into pug and glaze by the traditional process, and performing the working procedures of picking, rinsing, crushing, grinding, ageing and the like; and then molding: manually drawing, carving, kneading and rubbing the blank for molding; and (3) final firing: biscuit firing at about 800 ℃, glazing by a glaze dipping method, glazing for 1 or 2 times according to the color requirement of a product, and firing by reducing fire. Although iron ore is added in the preparation of the outer glaze in the patent application of CN102503365A, the amount of the added iron ore is small, the weight percentage of the added iron ore is only 2-3%, particularly, tourmaline powder without nano-scale particles is not added in the patent, and the nano-scale tourmaline has a good piezoelectric effect. In the patent application CN101700167A, although it is mentioned that the ru porcelain bowl has the function of keeping fresh, the component capable of forming the function of keeping fresh in the porcelain material is added with green agate, because the technical solution of the application lacks the substance with piezoelectric magnetic substance and the effective combination of various magnetic substances, the application does not use iron ore and silica, so the application does not have the function of magnetization and health care effect. Therefore, the preparation method and the ingredients of the porcelain are single, and the prepared porcelain has no good effect.

In the invention, because the mesh numbers of the tetraoxide trisome and the tourmaline powder are different, the properties of the manufactured products may have differences. Experiments prove that the performance is best when the mesh number of the ferroferric oxide and the tourmaline powder reaches 20000 meshes, namely Dn50 is less than or equal to 100 nm; the experiment adopts a method of detecting the concentration of negative ions to evaluate the efficacy.

For example, when the parts of ferroferric oxide, the tourmaline powder and the diatomite are 50 parts, 100 parts and 30 parts respectively, the diatomite is set to be 800 meshes for testing, and the specific performances are shown in the following table (1):

As can be seen from the table (1), the mesh numbers of the ferroferric oxide powder and the tourmaline powder are different, the detected negative ion concentrations are different, and the mesh numbers of the materials are different, the performance difference is larger, so that the table (1) can show that the concentration of the negative oxygen ions is increased along with the increase of the mesh numbers, when the mesh number is 20000, namely Dn50 is less than or equal to 100nm, the negative ion concentration reaches 19800, and the protection range of the invention is that the concentration of the negative ions generated by the functional material is 1 ten thousand per cm/cm³And above, 1 ten thousand/cm³When the above steps are carried out, the effect is good; therefore, the ferroferric oxide and tourmaline powder nano-particles in the inventionThe particle size Dn50 is less than or equal to 100nm, and the anion concentration can ensure enough efficacy.
