Non-radiation ceramic tile with high whiteness and manufacturing technique thereof

Abstract

The invention discloses a ceramic tile with a high whiteness and no radiation as well as the manufacturing method thereof. The weight percents of the main raw materials of the ceramic tile is: 15-60 wt.% of burning talcum, 15-30 wt.% of feldspar, 5-30 wt.% of porcelain sand, 20-28 wt.% of black mud. The steps of manufacturing method is as follows: (1) calcining the talcum; (2) the manufacturing process is: raw materialsbatchingball millingremoving zirconiumspraying and millingmouldingdryingpenetratingburningpolishing; (3) doing a strict anti-pollution treatment after polishing. The calcining temperature of the talcum is: 1200 DEG C; the calcining temperature of the ceramic tile is 1210-1230 DEG C; burning period is: 60-80 minutes; whiteness is: about 80 DEG. The invention firstly does a pre-burning treatment to the talcum material in 1200 DEG C, thus it manages its sheet structure and removes volatile with a high temperature. The disposed material is without greasy texture and the dosage will not influence the products molding.

Description

technical field [0001] The invention relates to a building decoration material and a manufacturing method thereof, in particular to a high whiteness non-radiation ceramic tile and a manufacturing method thereof. Background technique [0002] With the development of society, people's living standards are improving day by day, and people's requirements for the quality of life are also increasing day by day. Natural, comfortable and environmentally friendly building decoration materials have become a new field of research and development in today's construction industry. In the prior art, high-whiteness ceramic tiles (ultra-white bricks) have a decorative effect similar to high-grade natural stone—Alabaster, and have become the object of choice for customers and have a broad market. However, due to the high whiteness requirements for raw materials, The supply of raw materials has always been very difficult, not only the price is high, but also the quantity is small, so it is dif...

In the prior art, high-whiteness ceramic tiles (ultra-white bricks) have a decorative effect similar to high-grade natural stone—Alabaster, and have become the object of choice for customers and have a broad market. However, due to the high whiteness requirements for raw materials, The supply of raw materials has always been very difficult, not only the price is high, but also the quantity is small, so it is difficult to use it stably in production; and the use of chemical raw materials with whitening effect - zirconium carbonate, although it can achieve a certain whiteness, but at the same time brings the radioactivity of the product. Seriously exceeding the standard, its price is also very high. It is now an urgent need for manufacturers to find an alternative raw material with stable storage and no radiation. Talc is abundant in my country and has high quality, especially high whiteness. It can reach more than 90 degrees. In the ceramic industry, talc raw material is used as an auxiliary material, and the combined usage is only 1-3%, mainly because the flaky structure of talc makes the raw material itself have a greasy feeling. When used in the formula More will cause molding difficulties
