Product Description

Refractory ceramic setter plates, high-tech products, are technical supporting parts for the high temperature furnace sintering. With the ceramic setter plates, the sintered products will be heated evenly. That will reduce energy consumption and accelerate sintering speed, improve yields

 

Product Feture:

* High corrosion-resistance.

* High mechanical strength.

* Lower possibility of crack by thermal shock.

* Longer service time

 

Properties of Alumina

Alumina has a high melting point, high hardness and high mechanical strength, although mechanical strength is reduced at temperatures above 1000°C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced. Alumina is an electrically insulating material, with a high electrical resistivity, increasing with purity.Good chemical stability of alumina, leads to a high corrosion resistance. It is insoluble in water and only slightly soluble in strong acid and alkaline solution.

Q:How can the ceramic tableware distinguish 28 heads and 56 heads?
Due to sophisticated materials, fine production, strict standards, so the value is higher than other kinds of porcelain. Join the firing process and bone carbon unique, the impurities in the clay was removed, bone is more white and delicate, transparent, lightweight, small flaws, and thinner than general China, there is a special kind of clean feeling in the vision, the intensity is two times higher than general porcelain, daily-use porcelain. The higher the content of bone powder, the clay composition is relatively low, in the process of making the more easy to burn crack, in the shape of the need for higher technology, increased the difficulty of burning, so more precious.In one experiment, the 4 Mug pad on a Rolls-Royce under the wheels, the 4 crystal glass was capable of supporting the weight of the car!High-grade bone china porcelain (bonechina), shell porcelain, pearl porcelain etc.. As the shell porcelain, pearl porcelain almost no industrial production cost is too high, so China is the world's most recognized high-grade porcelain.
Q:Is purple pottery made of pottery?
Purple sand teapot is a kind of pottery tea set produced in Jiangsu area of Yixing in Ming and Qing dynasties. It's pottery, not porcelain.The similarities and differences between pottery and porcelain:Tao and the porcelain capital are the art of using the earth as the noumenon language, but there are also differences between the two. The basic materials of pottery and porcelain are the same. The ancients said, "the essence of pottery is porcelain."". In contrast, for the pure white porcelain, non absorbent, with transparency, so describe Jingdezhen porcelain as thin as paper, such as the sound of white snow. The pottery is different, although there are white, but less than the whiteness of porcelain, hydrophilic, opaque. Porcelain is usually glazed, but earthenware is not necessary; purple sand is a glaze without glaze.
Q:The difference between ceramic pot and purple clay pot
False news have burst in the United States, Joyoung brands such as purple pot, purple insiders have said: "for the production of high-grade teapot Yixing aggregate surplus more, but for the production of a large number of so-called" purple clay pot "" Purple pot "with purple material is impossible!"
Q:Ceramic pot for a long time, how to clean the dirt?
Very simple, heating water soak overnight, second days just wash. No, just one more night.
Q:What are the ceramic industry bases in China?
Zibo ceramic industry: the rapid development, construction ceramics production has now ranked second in the country, is rarely able to compete with Foshan. Zibo production area is the biggest advantage of its sales area of the radiation surface is very wide, up to the northeast, North China and East China, radiation radius is great, in such a large radiation surface, medium and low-grade ceramic products have an advantage. Secondly, Zibo has a comparative advantage in energy.Fujian ceramics: total production after Guangdong and Shandong, is the country's third largest total production of ceramics. Quanzhou, Jinjiang is undoubtedly the largest ceramic industry base in Fujian, Quanzhou, Jinjiang ceramic tile production direction has shifted to imitate the sense of stone outside the main direction of brick, out of its own characteristics of a road. Quanzhou city in 2011 a total of 157 ceramic enterprises, 415 production lines put into operation (including the city of Jinjiang built 330 production lines), daily production capacity of 3 million 387 thousand square meters of ceramic tiles (excluding tile line).
Q:What kind of ceramic bowl is good?
Ceramic bowl, preferred high temperature, underglaze colorThat can be used in microwave ovens, and looks goodCan search; pottery goods sinksHigh temperature hand-painted, non-toxic harmless. Rest assured that health is the top priority
Q:Vary render ceramic parameters
Basic parameters: pottery, white, anti.254, hook, philippines,Porcelain: diffuse, white, anti.180-220, high gloss, 0.88 gloss, 0.9 hookCeramic: diffuse, white, anti.160, high light, 0.75 hooksSingle parameter is useless, you have to understand the meaning of it, after the figure of material without texture, not only material problems, lighting effects are also great
Q:Ceramics with excellent products and first-class goods is how divided?
At present, the standards for ceramic products are: first-class, first-class, two, two grade, qualified products and so on.But the standards here often change. Because the burning of each ceramic device is difficult. Products that are easy to burn, excellent, first class, are well distributed. Difficult to produce products (easily flawed), the share is not so clear.The best products are not allowed to have spots or blemishes on the ceramic surface,First on the surface of the ceramics is not more than three of small diameter spots, or pores, needle etc..
Q:How is the quality of ceramics assessed?
The second is for gifts, gifts with the general choice of fine ceramics, so that ceramic exquisite workmanship, such as imperial concubine porcelain, porcelain delicate, white whole body, good light transmission. Particularly high ornamental. Also, choose flowers that are exquisite and not too rough. Why?. Because the flower surface is too thick, if you use nail button down, then this will be thrown. If the surface is smooth, slightly better feel, as if in touch grandpa Mao's head like. This is good, slightly concave and convex.Well, in general, pick ceramic ah, we have three steps:The first step is to look at what it looks like, look at the color, the ceramic to be white, the body without black spots, cracks, and so on. It depends on whether the design is harmonious and exquisite, whether it is light and transparent, whether the lines are neat and exquisite.The second step to touch: to feel with your hands. Is the edge of the body smooth?. Is it too bumpy?. Or is the flower surface too rough?. Also, such as bowls, that is, the soles of the feet is too rough or too slippery, too coarse, there is no fine grinding. It's too slippery. It's not safe. The table may slip off (especially with water and the desk is not normal)The third step: to put the bowl or cup, placed in the flat palm, beat with stingy things. The voice is crisp and melodious. It's a fine porcelain.
Q:Ceramic data
Ceramics are the general name for pottery and porcelain. Chinese back in about 80002000 BC (Neolithic) invented pottery. Ceramic materials are mostly oxides, nitrides, boride and carbide. Common ceramic materials are clay, alumina, kaolin and so on. Ceramic materials generally have higher hardness, but less plasticity. In addition to the use of utensils and decorations, it also plays an important role in the development of science and technology. Ceramic raw materials are the vast resources of the earth, and clay has been hardened. And the nature of the clay with toughness, at room temperature, water, plastic, micro dry can be carved, all dry can be grinding; burning to 700 degrees, can be pottery, can hold water; burning to 1230 degrees is porcelain, can be completely non absorbent, and high temperature, corrosion resistance. The flexibility of its use in today's culture and technology, there are a variety of creative applications
