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

Bedane utama antarane bata lempung lan bata alumina tinggi yaiku isi aluminium lan kepadatan massal.

Bata kanthi isi 40-48% aluminium yaiku bata lempung. Bata lempung duwe indikator beda N-1, N-2, N-3, lan N-4 ing standar nasional. Ing produksi lan panggunaan, bata-bata lempung N-2, N- 3 digunakake akeh, lan uga produk umum sing diproduksi dening akeh pabrikan. Kapadhetan volume antara 2.1-2.15. Ing bata bata lempung N-1, sawetara indikator luwih dhuwur tinimbang bata alumina kelas dhuwur.

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.

Werna tampilan bata lempung lan bata kelas dhuwur kelas telu isih beda. Bata lempung wernane kuning abang, lan bata kelas dhuwur kelas telu putih lan kuning.

Ana bedane bobot ing antarane bata lempung lan bata alumina kelas telu sing dhuwur. Bata lempung jinis bata sing padha luwih entheng tinimbang bata alumina kelas telu sing luwih dhuwur. Suhu tembak uga luwih murah 20-30 ° C.

Bata tanah liat lan bata alumina kelas telu dhuwur nduweni beda kekuatan kompresi lan suhu empuk sing mbukak. Kekuwatan compressive bata lempung yaiku 40Mpa, dene kekuatan kompresi bata alumina kelas telu dhuwur yaiku 50Mpa. Beban alus saka bata lempung uga luwih dhuwur tinimbang kelas telu. Réfrakabilitas bata aluminium 30-40 ℃, lan tahan maneh udakara 30 ℃.
