What is the difference between clay bricks and three-level high alumina bricks?

Die belangrikste verskil tussen kleistene en hoë-alumina-stene is aluminiuminhoud en grootmaat digtheid.

Stene met ‘n 40-48% aluminiuminhoud is kleistene. Klei stene het verskillende aanwysers van N-1, N-2, N-3 en N-4 in die nasionale standaard. In produksie en gebruik word N-2, N-3 kleistene wyd gebruik, en dit is ook algemene produkte wat deur baie vervaardigers vervaardig word. Die volumedigtheid is tussen 2.1-2.15. In die geval van N-1 kleistene is sommige aanwysers hoër as derdegraadse hoë aluminiumoxidestene.

Bricks with 55% aluminum content are third-grade high-alumina bricks with a bulk density between 2.15-2.25. At present, due to the production area and raw materials, the aluminum content of clay bricks is about 56%. The aluminum content of the clay bricks in Xinmi, Henan is about 56%, and the body density is above 2.15, which is basically a third-grade high-alumina brick. Moreover, the firing temperature is high, and the chemical index is not lower than the third-grade high alumina brick, but there is a difference in the softening temperature of the load.

The aluminum content of the three-level high alumina bricks currently produced is about 63%, and some have 65%. The body density is above 2.25, and the load softening temperature is slightly lower. In terms of chemical indicators, it is only different from the second grade high alumina bricks in unit weight and load softening temperature.

Die voorkoms van kleistene en derdegraadse hoë-alumina-stene is nog steeds anders. Kleibakstene is rooi-geel, en derdegraadse hoë-alumina-stene is wit en geel.

Daar is ‘n verskil in gewig tussen kleistene en graad drie hoë aluminiumoksiedstene. Dieselfde kleistene van baksteen is ligter as graad drie hoë aluminiumoksiedstene. Die vuurtemperatuur is ook laer met 20-30 ° C.

Klei stene en graad drie hoë alumina stene het die verskil in druksterkte en lasversagtingstemperatuur. Die druksterkte van kleistene is 40Mpa, terwyl die druksterkte van graad drie hoë aluminiumoksiedstene 50Mpa is. Die sagte vrag kleistene is ook hoër as dié van graad drie. Die vuurvastheid van aluminiumsteen is 30-40 ℃, en die vuurvastheid daarvan is ongeveer 30 ℃ laer.
