Red with the granite plate production process and points to note
Nov 23, 2016

As the Red Stone popular at home, as well as international markets (especially in the Middle East) needs all along the red stones are stones of mainstream best-selling color, especially red granite, the demand is very strong. But less quantity of natural red granite, in particular, had some good red granite/marble varieties are now broken the, which makes stone (granite) red plate market is growing up. But sometimes, due to the natural characteristics of stone, which will inevitably have a lot of color change, therefore, sometimes because the project requires, we sometimes have to use stain to adjust the color number of larger stone (granite).

Here to introduce red with the granite plate production process and technology:

First dissolution of ferric chloride with water, and add a small amount of catalysts made staining solution.

Then put into granite and completely soaked in dye solution.

In out after a certain period of immersion cleaning, drying, color is given the red granite.

(Note that the soaking time depends on the stone, color, water absorption, stone clearance, such as different)

Production process points for attention:

Concentration: different concentrations have different color effects, production should be seen in circumstances in which the General concentration of 20% is the best.

Soaking time: to have enough time, too short a time coloring is bad, but too long are not productive. Take 3-4 hours as well.

The PH value of the solution: the PH value is too large and too small to change color after the granite color and gloss is good, and generally the 2 is the best.

Drying temperature: General at 200-250 c (Celsius).

Drying time: usually about 2 hours.
