Important Buying Gypsum Tips

   For buying gypsum pay attention to these items:

1_ The  higher the percentage of sand in gypsum is the lower its quality will be and vice versa.

2_ The lower the pH value of gypsum is the higher its quality will be.

3_ Salinity (expressed as EC) is the most important factor in selecting high quality gypsum. The lower the salinity         (EC value) of gypsum is the higher its quality will be.

4_ The higher the Ca content of gypsum is the better its quality will be.

5_ Magnesium (Mg) is an undesirable element in gypsum: the higher the Mg content of gypsum is the lower its quality will be.

6_ The lower the sodium (Na) content of gypsum is the better its quality will be.

7_ The important parameter of the percentage of gypsum shows the purity of the material: the higher the percentage of gypsum in the product is the better its quality will be.

8_ The lower the percentage of TNV (total neutralizing value) in gypsum is the higher its quality will be.

9_ The higher the Ca/ Mg ratio is the higher its quality will be.
