Zirconia ceramic rod is made by isostatic pressing technology, which forms uniform, dense and smooth ceramic layer and transition layer at high temperature and high speed. Because of the advanced manufacturing process and high cost, it is suitable for the use of precision ceramic parts, and its wear resistance is stronger than other ceramic rods, generally used as a high wear-resistant place.
The metallization of zirconia ceramic rod is to stick the ceramic rod on the inner wall of metal with high temperature resistant strong adhesive, and form a solid anti-wear layer after heating and curing. The production process of the product is relatively simple, the production cycle is short, and the cost is relatively low. Technical specifications: Mingrui ceramics has various sizes of ceramic bars, can also be customized production according to customer needs. The metallized ceramic rod is basically unlimited in size, and its diameter ranges from 0.5mm to 160mm, and even more can be produced.
The drilling of ceramic rod is to stick the ceramic rod with hole in the middle to the inner wall of metal with high temperature resistant strong adhesive, and at the same time, with the spot welding process, the ceramic is firmly welded to the inner wall of steel sleeve through the small hole. To protect the solder joint, screw on the ceramic cap. Each porcelain rod not only relies on each other, but also forms corresponding angles, so that the porcelain rods are closely connected without gaps; when the last one in a circle is closely embedded, 360 mechanical self-locking force is formed between the porcelain rods. The production process of the product is relatively complex, the production cycle is long and the cost is high.
The one-piece wear-resistant ceramic bar is made by burning the ceramic bar as a whole and pouring it into the steel sleeve with special filler. The ceramic rod has smooth inner wall, good sealing performance, good wear resistance and corrosion resistance. But this kind of product has a long production cycle and high cost.
The composite rod has the advantages of high strength, good toughness, impact resistance, good welding performance, high hardness, high wear resistance, corrosion resistance and heat resistance of corundum porcelain, which overcomes the characteristics of low hardness, poor wear resistance and poor toughness of the metal rod. Therefore, the composite rod has good comprehensive properties such as wear resistance, heat resistance, corrosion resistance, mechanical impact resistance, thermal impact resistance and weldability.
As zirconia ceramic rod has wear-resistant, corrosion-resistant and heat-resistant properties, it can be widely used in electric power, metallurgy, mining, coal, chemical industry and other industries as corrosive media, and is an ideal wear-resistant ceramic rod.
