Dissolution

Without surface treatment products

In order to avoid agglomeration, directly put the product in the above 90 ℃ hot water does not stop stir until completely dissolved, then started to cool solution.

  • Hot water(> 90 ℃)
  • scattered
  • to room temperature
  • The water cooling
  • solution

Surface treatment products

Surface treatment products in order to avoid in the wet mixed purposes such as paint and latex paint caking specially developed.

  • Directly dispersed in cold water
  • Mixing adjustment
  • to room temperature
  • The water cooling

Used In

  • building

    For the machine and manual spraying mortar mortar, drywall joint agent, ceramic tile cement and jointing agent.

  • binder

    Can increase the glue and glue consistency and form a film adhesive dispersion.

  • coating

    Can be used as thickening agent, protective colloid, pigment, suspending agent, so as to improve and solubility.

  • Personal care

    As a thickening agent, dispersant and emulsi fier used in lotion, shampoo, toothpaste, and other products.

  • The pharmaceutical

    For emulsifier and dispersant in the ointment, cohesive role in medical ointment pulping, shrinkage and coating effect in the tablets.

  • ceramic

    Increase water retention in the machining process and the role of lubrication.
