Preparation method for different types products |
Dry-mixed type (D type) fluid loss additive can be made when mix high purity powder (P type) with materials such as slag, silica flour, flyash etc . Dual-purpose type (T type) fluid loss additive can be made when mix high purity powder (P type) with salt. Liquid product (L type) is made when high purity power is dissolved in water with a certain concentration. If it is not put into use immediately after production, preservative and germicide should be added to prolong its shelf life. |
