China ceramic mug suppliers : Various raw materials for ceramic coffee mugs (1)

 From Xinxiang Ceramic Mug Manufacturers,The raw materials of ceramic mugs are mainly from rocks, which are mainly made of silicon and aluminum. This kind of rock is also used as raw material for ceramic mug, which is hardened by artificial heating, which is similar to the formation of igneous rock. Therefore, from the chemical point of view, the composition of the custom ceramic coffee mugs is no different from that of the rock. If it is a ceramic cup made of silicon and aluminum, the main raw materials are as follows:

1. Quartz - chemical composition is pure silica (SiO2), also known as silica. This kind of mineral has no stickiness even if it is broken into fine powder, which can be used to make up for the defect of excessive viscosity of ceramic raw materials. When the temperature is above 780 degrees, it is unstable and becomes tridymite, and begins to melt at 1730 degrees.

2. Feldspar is a compound mainly composed of silica and alumina, mixed with sodium, potassium, calcium, etc. There are many kinds of them because of their different components. Generally, some rocks with more feldspar are called feldspar, and some are named after their origin. Several representative feldspars and their compositions are listed in Table 1. The first three are pure theoretical components, while the latter contain all impure materials in rocks.

Albite and anorthite melt with each other in various proportions and become various feldspars. These are called plagioclase and their properties depend on the ratio of albite to anorthite. There is also a kind of orthoclase (K-feldspar) with the same composition but slightly different shape, which has been misinterpreted as orthoclase. In fact, this kind of feldspar should be called "microcline".

3. Porcelain clay (also known as "kaolin") - porcelain clay (h4al2si2o9) is the main raw material of wholesale ceramic mugs. It is named after the kaolin produced near Jingdezhen, the first kiln factory in the world. Later, the Chinese pronunciation of "kaolin" evolved into "kaolin" and became an international noun. Pure porcelain clay is a kind of white or gray white soft mineral with silk luster.

China ceramic mug manufacturers tell Formation and prevention of pinhole in ceramic mugs

 From Xinxiang Ceramic Mug Manufacturers,In the production of ceramic mugs, pinhole is a very common quality problem. In particular, the problem of pinhole is more serious. So what are the reasons for pinholes on ceramic mugs? How to prevent it?

The formation and prevention of pinhole on ceramic mugs can be divided into three reasons:

 1. The molding mold is too wet;

 2. The slurry is too viscous;

 3. The grouting speed is too fast.

Therefore, to solve the pinhole problem, we must make a general judgment from these aspects, and then analyze and solve the specific problems. If the mold problem, we should consider whether the mold frequency is too fast, or natural weather problems, or indoor drying equipment problems, or the mold has reached the use limit, need to replace a new mold.Custom ceramic coffee mugs

If there is a mud problem, it is necessary to comprehensively consider various reasons to solve the problem. Mud viscosity is not necessarily due to the small amount of water added during the grinding process or the problem in the proportion of other raw materials. It may be that the viscosity of the mud is affected by changes in weather and temperature. Therefore, it is necessary to comprehensively consider and solve the problem from various aspects.

Of course, the grouting speed should be comprehensively analyzed according to the specific environment, temperature and other factors.Wholesale sublimation mugs

Ceramic mugs with lid products have very complex molding factors, these factors affect and restrict the quality of products, so to learn ceramic technology, we must first develop the habit of thinking about problems from many aspects, which is the premise of learning ceramic technology.
