Alumina Ceramics:
Alumina Ceramic rings have the common advantages of both metal and polymer materials. Because of their many advantages, they have been concerned and widely used, and they play a very important role. The production process of ceramic rods is cumbersome and requires production processes such as cutting, grinding, grinding and polishing. However, compared with the same type of products made of Other Materials, the demand for ceramic rods is large and it has become higher because it has the following advantages.
Very weather-resistant
The ceramic rod uses zirconia or alumina as the production material. Compared with the products of the same category, the advantages are quite obvious, and it has strong weather resistance. No matter the sunlight, rain, or moisture, it has no effect on the surface and substrate of the ceramic rod. Corrosion-resistant ceramic rods are also very stable in color under ultraviolet radiation. In terms of impact resistance, strength, and elasticity, they are in line with international standards.
Extremely stable
Ceramic rods are generally made of zirconia, which is a relatively advanced technology in the industry. First, it is easier to clean, has good fire resistance characteristics, does not melt, drop or explode, and can remain stable for a long time. , So the stability is extremely strong. In addition, ceramic rods are easy to maintain, without the need to add any anti-corrosive paint or protective layer on the surface, which is easy and convenient to use and has a long life.
High abrasion resistance
The ceramic rod uses high-precision raw materials, which enhances the mechanical strength and hardness of the ceramic during the high temperature firing process. Therefore, ceramic rods have a very good performance in terms of impact resistance. After a long period of proof and multiple tests, the abrasion resistance is also very strong, and the shape will not be damaged after long-term use. In a variety of harsh working environments, the advantages of ceramic rods are even more significant, making acid-resistant ceramic rods the only choice under harsh conditions.
Ceramic rods are widely used in various fields due to their weather resistance, stability and high wear resistance. In addition to the use of ceramic rods in normal environments, in the harsh working environment of high temperature, high pressure and easy corrosion, the use of ceramic rods can not only ensure the normal operation of the instrument, will not break, wear, corrosion and other conditions, and will not damage instrument.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
