Problems solved by technology

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 br

Embodiment 1

[0027] First, 15-60% by weight of talc is pre-calcined at 1200°C, then 15-60% by weight of calcined talc is added to 15-30% by weight of feldspar, and stirred evenly at room temperature to form a mixed powder , then add 5-30% by weight of porcelain sand, 20-28% by weight of black mud, mix evenly at room temperature, and then form a blank for use through ball milling, zirconium removal, spray powdering and other processes. The treated billets are pressed and formed, and then dried and infiltrated. The blanks treated by the above-mentioned processes are placed in a kiln furnace, and fired for 60-80 minutes at 1210-1230°C. Polishing and decontamination processes make finished products.

[0028] The performance of the high-whiteness radiation-free ceramic tile made by the above process can reach: the product shrinkage rate is below 9.0-10.0%, the product water absorption rate is below 0.08%, the product flexural strength is above 40MPa, and the product whiteness is about 80°.

Embodiment 2

[0030] First, 45% by weight of talc is pre-calcined at 1200°C, then 45% by weight of calcined talc is added to 25% by weight of feldspar, stirred evenly at room temperature to form a mixed powder, and then 5% by weight of 25% by weight of porcelain sand and 25% by weight of black mud, mixed uniformly at room temperature, and then formed into blanks through ball milling, zirconium removal, spraying and pulverizing, etc. 1. Infiltration process process, put the blank processed by the above process into the kiln furnace, and burn it for 60 minutes under the condition of 1230 ℃, and then process it into a finished product through polishing and decontamination process.

[0031] The performance of the high-whiteness non-radiation ceramic tile made by the above process can reach: the product shrinkage rate is 9.1%, the product water absorption rate is 0.06%, the product flexural strength is 45MPa, and the product whiteness is 81°.

Embodiment 3

[0033] First, 35% by weight of talc is pre-calcined at 1200°C, then 35% by weight of calcined talc is added to 29% by weight of feldspar, stirred evenly at room temperature to form a mixed powder, and then 11% by weight of 25% by weight of porcelain sand and 25% by weight of black mud, mixed uniformly at room temperature, and then formed into blanks through ball milling, zirconium removal, spraying and pulverizing, etc. 1. Infiltration process process, put the blank processed by the above process into the kiln furnace, and burn it for 65 minutes under the condition of 1210 ℃, and then process it into a finished product through polishing and decontamination process.

[0034] The performance of the high-whiteness non-radiation ceramic tile made by the above process can reach: the product shrinkage rate is 9.3%, the product water absorption rate is 0.05%, the product flexural strength is 55MPa, and the product whiteness is 79°.

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.
