Objects are divided into three, six or nine grades, and bricks are divided into high, medium and low grades. I often hear people say that this brand of ceramic tiles is good and that brand of ceramic tiles is inferior. So how can we judge the quality of ceramic tiles? Cheap bricks do not necessarily mean good bricks, and expensive bricks do not necessarily mean good quality. Price is just a label. You must judge the quality of bricks from the source of product production.
1. The raw materials are different
The same equipment and the same process, why are the products produced different? The answer is that the raw materials used are different, and only good materials can make good products. The impurity content in the raw materials of ceramic tiles will greatly affect the quality of ceramic tiles. Currently, the best porcelain clay in China is produced in the hilly areas of South China.
2. The presses are different
The size of the press cannot determine the quality of the bricks produced, but a large-tonnage press can produce products that a small-tonnage press cannot. For example, a small-tonnage press cannot produce large bricks with a size of 800X1600mm. The tonnage of presses on the market now ranges from 200-7200 tons. The tonnage of the press directly determines the density and hardness of the ceramic tiles.
3. The production lines are different
A good ceramic tile factory has a relatively advanced, fully automated, modern production line, while an ordinary factory has a semi-automated production line that relies on manual operation by workers. The quality of ceramic tiles depends on lean production and control. Only the most advanced production lines can produce the best quality products. Good equipment and good production lines are the guarantee for producing good products.
4. BallGrinding is different
The quality of the ball mill, as well as the speed and time of ball milling, directly affect the density, wear resistance and anti-fouling ability of the ceramic tiles. Good ceramic tile manufacturers use large-tonnage ball mills to ensure that the coarse particles in the raw materials become finer and more uniform through long-term ball grinding with wear-resistant alumina balls, even as fine as only 1/3 of a human hair. Spend. Ordinary ceramic tile manufacturers use small-tonnage ball mills and low-aluminum balls. In order to save production costs and greatly shorten the ball milling time, although the prices on the market are low, there are great hidden dangers.
5. Iron removal is different
Hao Tile Factory uses highly magnetic electromagnetic rods to absorb iron filings, and the iron content is less than 0.1%, ensuring that the fired body has no black impurities and the brick body is pure. Ordinary manufacturers use ordinary magnetic rods to remove iron. The iron content is high, and black spots are prone to appear on the surface of the fired ceramic tiles.
6. It’s different
After the ceramic tiles are ball milled and screened to remove iron, they need a period of aging to allow the various impurities and chemical components in the raw materials to fully react and meet production standards. A powerful ceramic tile manufacturer can produce more than a thousand tons of raw materials each time and can reserve more than 180 days of inventory. The aging of raw materials requires a large amount of material and financial resources from the enterprise. In order to save costs and improve productivity, ordinary enterprises will greatly shorten the aging time.
7. Drying kilns are different
The length of the drying kiln determines the degree of moisture drying of the ceramic tiles. For example: the horizontal roller drying kiln used by Haochang can not only meet the drying speed of the green bricks, but also discharge the moisture of the bricks from the inside to the outside, so that the moisture content is less than 0.5%, and there will be no deformation during firing. The most important thing is that humanized settings can greatly improve the labor of workshop workers.condition.
8. The firing time is different
The length of firing time of ceramic tiles has a great influence on the quality of ceramic tiles. If the time is short, the ceramic tiles will not be burned through. We often see a black heart in the middle of the brick embryo, which is the reason why the ceramic tiles are not burned through. For example: for the same 320-meter-long kiln, the output of a good factory may be only one-third of that of an ordinary factory, because the firing time of a good factory is particularly long. 800*800mm vitrified bricks need to be fired for 70 minutes, while ordinary factories only take 40-50 minutes. The extension of the firing time ensures that the brick body is completely porcelain, as dense as a porcelain bowl, with high hardness and wear resistance!
9. The tests are different
Every brick in the factory undergoes machine inspection and manual inspection. Strictly inspect size, specification and color difference. The national standards are the same, but the internal control standards of each factory are different. Good factories have strict internal control standards, while ordinary factories have relatively loose internal control standards.
