A. Moving tablets are made of ceramics

(1) Ceramic sheets are formed by sintering at 1680 C at ultra-high temperature.

(2) Using corundum ceramics, the content of Al2O3 is more than 95%.

(3) The hardness of processed ceramics is HRA (> 85 degrees), flatness (< 0.0003 mm), parallelism (< 0.015 mm).

(4) The acid and alkali resistance of ceramics: stabilization of various inorganic acids and bases at room temperature

B. High strength synthetic material for fixing

(1) Its corrosion resistance is only inferior to that of PTFE. Except that hot concentrated nitric acid is corrosive to PTFE, hydrochloric acid, sulfuric acid and strong alkali can not dissolve it.

(2) After grinding, the flatness of the end face can reach the same level as that of the ceramic sheet, thus making the seal reliable.

The anti-impurity ability of the product is better than that of other structures when the end-face seal structure is adopted.
