In the large purple clay relief in the production process, manufacturing skills are very main techniques, because the concept of update, the original can not meet with the need of skills, especially how to make single purple brick every piece of dozens of kilograms, more than 10 centimeters thick in the fire burning under deformation, cracking and color, plump shape is flawless and perfect success. How to make large firing pottery relief in order to show the perfect effect? You look at Amway glass and steel sculpture factory specific steps:
When manufacturing materials, we must first consider how to deal with the problem of deformation of bricks and bricks. After countless experiments, we know that the composition and structure of purple clay pottery is the main source. We all know a knowledge, that is, ceramics are shortened two times in the manufacturing process.
One is that there is a shortening of drainage when it is dry.
Two is the firing temperature oxidation process also has a shortened, the two time shorten the process is very important, need more careful, otherwise fired out of the pottery became defective. During this period some because in a boring process of mud brick cracking, some are in the firing process of the cracking or blasting, the two processes have decided whether to burn out the perfect products. Then there is a pottery is also very important, that is the process of producing purple clay brick blank.
This process can be said to be killed, it is necessary to carefully manufactured, because each piece of Purple mud brick is by artificial chipped out. If careless manufacturing or the inside of the brick for making the uneven force left the air, or transfer approaches are wrong and other reasons, will constitute the internal structure of the brick body not only severe injury. So, before firing these questions is still not found, once into the kiln, then through high temperature sintering, is bound to crack and deformation, eventually become defective, it can not make up for the loss.
Third, the boring process is still very important, a dozen centimeters thick mud brick in natural air condition, it cannot be one hundred percent boring, in accordance with the request that it is necessary to enter the drying room drying. Because the air is full of water, and water is not directly into the brick kiln firing. The temperature in the kiln increased sharply within a short time, and the mud brick in the water could not be drained, it will form a Lengrebujun, occurrence of blasting, resulting in mud brick has not yet entered the burning zone is completely damaged. Fourth, is, in the firing time and strict control is divided into five. A temperature in the firing process of the kiln, including preheating, temperature rise, firing zone and cooling zone and cooling zone.
These zones are very important, as long as the accurate grasp of the time and temperature of the standard, can smooth over firing, especially the firing zone, the resolution is fired out of the purple brick color and the key agglomeration zone. If a long time to burn, the corresponding temperature will be too high, because the pottery brick becomes shorter is very small, the color will become dark dull; if time burning short, the temperature must not make pottery, brick burning with no more energy, because of shorter small volume is not up to the standard request, and the structure of the condensed lax, its color becomes thin and little, lack of connotation beauty should be. As long as the corresponding moment, with the temperature, burning out of the pottery relief, to vivid.
Fifth, in the installation of large pottery relief, because of its components and area are large and necessary is divided into several tens of square cm size section, which occurs between the joint section of doubt, this is a big problem now can't handle pottery products, but also because of the inherent nature of the data exists for the deficiency. And I will make full use of this disadvantage, transforming it into a new concept, constitute a common way of art.
In the manufacture of purple clay brick size, but the thickness of divergent, combined to row in a variety of ways, because the light and shadow effect, natural purple clay relief occurred a feeling of mystery: the uneven, down, both unified and rich, produce a variety of texture and rhythm by carving, and rich in modern sense, constitute a unique artistic language and incomplete beauty.
