 Product performance and use

 High-tech public color iron red type 110

    Appearance yellow red powder, particle size ≤ 0.1μm, with heat, light, strong color and other characteristics, suitable for color cement tile coloring and manufacturing color cement. In the manufacture of color cement industry, the product due to the color strength of up to 105%, mixed with white cement appearance is still bright red. According to different uses have different targeted products, performance over the national standard.

  High-tech public color card iron red 120 type

    Appearance yellow red powder, particle size ≤ 0.1μm. Compared with the 110 type, reddish phase, with heat, light, strong color and other characteristics, the same applies to the color of cement tile coloring and manufacturing of colored cement. According to different uses have different targeted products.

  High-tech public color iron red 130

    Appearance bright red powder, particle size ≤ 0.3μm, with strong color strength, absorption of ultraviolet and other characteristics, PH was neutral. It is suitable for the coloring of colored cement tiles and the manufacture of colored cement. Especially for the color of cement tile tinting, due to the PH value was neutral, to avoid the color tile salting out the white phenomenon, making the red color tile long to maintain a bright appearance. According to different uses have different targeted products.

          High-tech public color iron red 190-1 type

Appearance purple powder, compared with the 191-2 type, slightly lighter color, domestic for the manufacture of color pavement and rubber, plastic products, coloring. According to different uses have different targeted products.
