Method for preparing purple sand slime containing tourmaline iron sand

Abstract

The invention provides a method for preparing purple sand slime containing tourmaline iron sand. Ore and raw tourmaline scattered in a soft clay ore bed are artificially selected, purple sand ore is stacked in the open air in winter and summer for natural weathering, the weathered raw ore is aired, dried, ground by means of a hard stone mill and smashed into 60-mesh fine powder, 80-mesh fine powder and 120-mesh fine powder, and after the tourmaline ore is smashed and ground and ore powder is screened out by a 140-mesh sieve, water is added, the materials are mixed, evenly stirred and sealed for ageing; vacuum pugging, clay strip pressing, sealing and ageing are repeated for 3-5 times, and the purple sand slime containing the tourmaline iron sand is prepared. The slime prepared through the method is original, pure, free of chemical raw materials and artificial pigment and not likely to crack when purple sand ceramic products are fired, and the manufactured purple sand ceramic products are natural, environmentally friendly, good in quality, natural in texture, fine and smooth in hand feeling, good in light transparency and water color and good in color generation. Meanwhile, the purple sand slime has the effects of improving water quality and promoting blood microcirculation.

Description

technical field [0001] The invention relates to the technical field of purple sand pottery raw materials, in particular to a preparation method of purple sand mud containing tourmaline iron sand. Background technique [0002] The raw material of Zisha pottery is a kind of hydrous aluminosilicate mineral clay, which is formed by long-term weathering and geological processes of feldspar-containing rocks in the earth's crust. It is widely distributed in nature and has a wide variety. It is stored in most areas of my country Rich, his main components are silicon dioxide, aluminum oxide, ferric oxide, manganese dioxide, calcium oxide, magnesium oxide, potassium oxide, sodium oxide, titanium oxide and crystal water. There are many kinds of mud materials for purple sand pottery. Apart from the main red mud, purple sand mud, and green mud, there are also various colors such as white mud, black mud, yellow mud, and pine flower mud. Zisha pottery is not glazed, but fully utilized. The...

Problems solved by technology

[0003] At present, there are few high-grade purple sand raw materials, especially because of the random mining of purple sand mineral resources in the past, which seriously damaged the rational use of mineral resources, and purple sand mineral resources are becoming more and more scarce. Mining is restricted and protected. At present, most of the common purple sand products on the market are almost made of low-quality purple sand raw materials or purple sand tailings raw materials plus chemical raw materials, which not only endangers the health of the body, but also seriously affects the application and development prospects of purple sand pottery.
