Embodiment

[0026] (1) Blank preparation

[0027] Take 44 parts by weight of purple sand mud, 7 parts by weight of kaolin, 40 parts by weight of lithium petalite, 5 parts by weight of talc, 3 parts by weight of clay, and 1 part by weight of bentonite as raw materials;

[0028] ——The above purple sand mud is low-grade (tailings) purple sand mud produced in Yixing, which is processed by machine cone (mechanical hammering) for 8 hours; the above talc is obtained by calcination at 1200 °C, and the calcination time is 7 hours; the above Kaolin comes from Guizhou origin;

[0029] Mix the above raw materials and add water to carry out wet ball milling. The ball milled raw materials pass through a 220-mesh sieve. After passing the sieve, the raw materials are stored in the mud storage tank for aging. The aging time is 40 hours. After the old raw materials are filtered through a filter press, they are formed into mud After the filter press mud block is wrapped with cotton cloth, it is wrapped wit...

Abstract

The invention provides a preparation method of a red porcelain heat-resistant cooker, which is characterized by comprising the following production steps: (1) blank preparation; (2) roll forming; (3) clay billet trimming; (4) bisque firing; (5) bisque firing billet trimming; and (6) burning. The cooker product prepared by the method has the advantages of high qualification rate, no glaze layer on the surface, smooth body surface and high regularity, and has the peculiar favorable air permeability of the red porcelain product. The product quality satisfies the standard requirements in GB / T10816 'Red Porcelain Ware'; and as for the heat stability of the product, the porcelain body can not crack after 400-20 DEG C heat exchange once, thereby satisfying the heat stability requirement in the standard QB / T2580 'Fine Ceramic Cookers'.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a purple sand heat-resistant cooker and a preparation method thereof. Background technique [0002] Zisha products are a type of ceramic products. According to the description in GB / T10816-2008 "Purple Clay Pottery" standard: "It is made of special clay with fine texture and high iron content. Purple sand products." China has produced purple sand products since ancient times, and the representative place of production is Yixing, Jiangsu. The products are mainly pots, and there are also tableware and drinking utensils. [0003] Zisha mud is a kind of hydromica-quartz-kaolinite clay, which contains more iron minerals. Zisha mud has many producing areas in China, with Yixing Zisha Mine in Jiangsu as the representative producing area. For a long time, Yixing purple sand mud has been exploited disorderly, leaving some waste ore and low-grade purple sand mud (containing more impurities) call...
