The surface of alumina ceramic tube is flame retardant and fire-resistant, which will not affect its performance at 1200 ℃. Alumina ceramic tube is the key to all acid and alkali products and other chemicals. No matter it is chemical solvent, corrosive agent or other chemical dye, it will not affect the surface of ceramic tube.
2. The alumina ceramic tube is easy to clean:
The strong anti-corrosion ability of the surface of alumina ceramic tube makes it easy to clean with washing solution without affecting its color and surface, and the tight surface without penetration is not easy to adhere to dust.
3. Beautiful alumina ceramic tube:
After the alumina ceramic tube is fired, it can be processed by precision carving machine, and the fine carving lines are not easy to be damaged, so the ceramic tube is beautiful and generous.
4. Anti static of alumina ceramic tube:
Alumina ceramic tube is made of zirconia alumina, which is proved to be anti-static material, unless it has a certain degree of low conductivity.
5. Aluminum oxide ceramic pipe anti scratch:
The surface structure of the alumina ceramic tube is finished, which makes the ceramic tube not easy to be damaged under the action of the external hard object, and the ceramic tube has strong resistance to falling.
