specific Embodiment 1

[0028] Specific embodiment one: the environment-friendly bone lithium china without feldspar,

[0029] According to parts by weight, the formula of porcelain material is as follows: 25 parts of kaolin, 13 parts of quartz, 12 parts of raw ore, 50 parts of discarded sand after panning kaolin;

[0030] The components of the discarded sand after panning kaolin in parts by weight are as follows: 8.07% aluminum, 84.3% silicon, 0.07% iron, 0.02% titanium, 0.08% calcium, 0.03% magnesium, 6.7% potassium, and 0.73% sodium;

[0031] The pH of the discarded sandy soil after panning kaolin is 0.7.

[0032] The manufacturing process of the above-mentioned environment-friendly bone lithium china without feldspar comprises the following steps:

[0033] Step 1, elutriating the kaolin, separating the kaolin with high content from the sandy soil with low content;

[0034] Step 2, carry out sampling inspection to the discarded sand after elutriation, select the discarded sand that meets the sta...

Abstract

The invention belongs to the technical field of ceramic production, and specifically relates to feldspar-free environment-friendly bone lithium china. The feldspar-free environment-friendly bone lithium china is composed of kaolin, quartz, raw ore, and waste sandy soil after kaolin elutriation. In the formula of the feldspar-free environment-friendly bone lithium china, waste sandy soil generated during the kaolin elutriation process is used to displace the feldspar to produce bone lithium china whose performance is higher than the national standard. The waste sandy soil is converted into resources, waste is turned into valuable resources, the production cost of bone lithium china is greatly reduced, and thus the technology has a very important economic and social benefit. The manufacturing technology combines the conventional technology and the modern scientific technology together, has the advantages of simpleness, high production efficiency, and low rejection rate, and is capable of carrying out burning and moulding in one step.

Description

technical field [0001] The invention belongs to the technical field of ceramic production, and in particular relates to a feldspar-free environment-friendly bone lithium porcelain and a manufacturing process thereof. Background technique [0002] In the prior art, it is necessary to add feldspar as a flux mineral to sinter with quartz, kaolin, talc, etc. in daily-use porcelain, and feldspar has become an indispensable component in traditional ceramics. Recent studies have shown that feldspar has strong radioactivity, especially the increasing amount of feldspar used in the production of various ceramics, making the interval between mining and use of feldspar very short, resulting in radioactivity that cannot decay to a safe range, resulting in long-term Use of this product may cause adverse health effects. [0003] In order to solve the above problems, many ceramic producers use other materials to replace feldspar. For example, the invention patent application whose authori...
