Abstract

A low-water absorption stoneware product is prepared from the following components in parts by weight: 30 to 40 parts of sodaclase, 15 to 25 parts of quartz, 40 to 50 parts of kaolinite and 1 to 2 parts of additive; the percentage content of K, Na, Fe and Ti in the stoneware product is guaranteed to be the followings in percentage by weight: 1 to 1.5 percent of K, 2.5 to 3 percent of Na, less than 0.9 percent of Fe, and less than 0.15 percent of Ti. The additive is a mixture formed by mixing lithium porcelain stone or lithium porcelain stone with soapstone; the mixing ratio of the lithium porcelain stone and the soapstone is optional, and can be selected according to the requirements of the cost and the quality of a product. The production method of the low-water absorption stoneware product comprises the steps of sorting, batching, ball milling, slurry discharging, squeezing, primary refining, refining, staling, blank making and burning; according to the invention, through rationally selecting raw material formulation and adding moderate lithium porcelain stone or lithium porcelain stone to be mixed with the soapstone to form the mixture serving as the additive, not only is the conventional firing temperature of the stoneware followed, but also the water absorption can be effectively lowered, and the product quality is ensured.

Description

technical field [0001] The invention relates to a ceramic product and a manufacturing method thereof, in particular to a stoneware with a low water absorption rate and a manufacturing method thereof, and is mainly suitable for making stoneware and its products. Background technique [0002] Stoneware, also known as "stone-bodied porcelain", is one of many types of ceramics. It is fired at a high temperature of about 1,200°C to achieve vitrification (that is, similar to glass, impermeable to liquids). Stoneware is loved by users all over the world because of its compact body, high strength and good thermal stability, lead-free, non-toxic, high-quality and environmentally friendly. However, in the process of making stoneware, the high water absorption rate of stoneware has always been a difficult problem in daily-use stoneware products. Under the premise of controlling cost and quality, appropriate water absorption rate is conducive to improving the service life of products. ...
