Alumina lining
Ways to distinguish good from bad
The wear-resistant ceramic lining that looks good to the eye has a flat surface, no black spots, smooth and not rough, and uniform color. The color of the porcelain wear-resistant ceramic lining is: White, the porcelain wear-resistant ceramic lining plate is light yellow, and the color of the good wear-resistant ceramic lining plate has the texture of jade.
To measure the tolerance, use a vernier caliper to measure the length, width and height of the wear-resistant ceramic lining plate. Alumina ceramics have a certain shrinkage ratio, and the dimensional tolerance error is plus or minus
To measure the density, the alumina content can be determined by measuring the density. It is estimated that the density of the porcelain wear-resistant ceramic lining plate is greater than /, and the density of the porcelain wear-resistant ceramic lining plate is /. The accurate density measurement should use the drainage method
. If the experimental conditions are met, the hardness can be measured according to the prescribed method
Do wear-resistant experiments, use a sandblasting machine to measure wear within minutes at pressure/distance, spray angle, and time.
