The ceramic patch wear-resistant tube is the most common form of ceramic wear-resistant tube. Due to the characteristics of convenient processing, low cost and good wear resistance, the chip ceramic tube is more widely used in the industry than other wear-resistant tubes. The ceramic patch is a special corundum ceramic made of AL2O3 as raw material and rare metal oxide as solvent, sintered at a high temperature of 1730 ° C, and then bonded with wear-resistant adhesive to form a wear-resistant ceramic patch. It is required to choose wear-resistant ceramic patches and technical conditions to meet the special needs of users. The wear resistance of the wear-resistant ceramic patch is 280 times that of manganese steel and 180.5 times that of high-chromium cast iron.
(1) Processing of lined ceramic sheet, handmade
Features of SMD Ceramics:
The ceramic sheet is pasted on the steel pipe with high temperature wear-resistant glue to play a wear-resistant role, and the pipe is generally white. Generally used for large diameter pipes
Advantages: ceramic patch wear-resistant pipes have good wear resistance (than self-propagating combustion), and have a long service life
(2) Wear-resistant tube lined with ceramic sheets, the workers are very careful, and the ceramic sheets are firmly pasted.
Disadvantages of ceramic patch wear-resistant pipe:
Temperature resistance: Due to the influence of the temperature of the adhesive, it is not resistant to high temperature.
Easy to fall off: If the medium is corrosive, it is easy to corrode the steel pipe between the gaps of the patch.
