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

Ny tena maha samy hafa ny biriky tanimanga sy ny biriky avo-alumina dia ny atiny aliminioma sy ny hakitroky betsaka.

Ny biriky misy atiny aluminium 40-48% dia biriky tanimanga. Ny biriky tanimanga dia samy manana ny mari-pamantarana N-1, N-2, N-3, ary N-4 amin’ny fenitra nasionaly. Amin’ny famokarana sy fampiasana, biriky tanimanga N-2, N- 3 no be mpampiasa, ary vokatra mahazatra ihany koa vokarin’ny mpanamboatra maro. Ny hakitroka dia eo anelanelan’ny 2.1-2.15. Raha ny biriky tanimanga N-1, ny tondro sasany dia ambony noho ny biriky alimina ambaratonga fahatelo.

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.

Ny lokon’ny biriky tanimanga sy ny biriky alumina avo lenta fahatelo dia mbola hafa ihany. Ny biriky tanimanga dia mavo mena, ary ny biriky ambaratonga ambaratonga fahatelo kosa fotsy sy mavo.

Misy fahasamihafana eo amin’ny biriky tanimanga sy biriky alumina avo telo. Ireo biriky tanimanga karazana mitovy amin’io dia maivana kokoa noho ny biriky alumina avo lenta. Ny mari-pana mitifitra dia ambany ihany koa amin’ny 20-30 ° C.

Ny biriky tanimanga sy ny biriky alumina avo telo dia manana ny fahasamihafana amin’ny tanjaka mamoritra sy ny mari-pana malefaka. Ny tanjaky ny biriky tanimanga dia 40Mpa, raha ny tanjaky ny biriky alumina avo telo dia 50Mpa. Ny enta-mavesatry ny biriky tanimanga koa dia ambony noho ny kilasy fahatelo. Ny tahan’ny biriky vita amin’ny aliminioma dia 30-40 ℃, ary ny fihenan-tsainy dia 30 ℃ ambany.
