              Customer Case

              Drilling / beneficiation

              Product introduction

              I、 Product name

              Carboxymethyl cellulose, carboxymethyl starch (CMC, CMS)

              Ⅱ、 character

              Appearance, dissolution and solubility

              This product is white or yellowish flocculent powder. It is nontoxic, odorless, tasteless,

              soluble in water, and soluble in glycerine when a small amount of water exists. It has good

              compatibility and synergistic effect with other water-soluble adhesives, softeners and resins

              ★ Hygroscopicity

              The equilibrium water content of CMC increases with the increase of D S value and

              air humidity, and decreases with the increase of temperature. When the room temperature

              and equilibrium humidity are 80%-85%, the equilibrium water content is more than 26%

              ★ Filmo genicity

              CMC films with high viscosity and high

              molecular weight have high strength an

              d

              flexibility. Some water-soluble resins are

              used as crosslinking agents, and the mixed

              solution of CMC is used to cast the film

              After further drying and plasticizing treatment

              the film can become an insoluble product

              Water insolubility can also be obtained b

              treating the dried CMC with aluminum salt

              Viscosity and rheology

              At the same D S value, the viscosity

              increases with the increase of concentration

              decreases with the increase of temperature,

              and rises after cooling. When the ph value of

              1% CMC aqueous solution is 6.0-9.0, the viscosity is the highest, and when the pH value is<6or>11.5

              the viscosity begins to decrease The viscosity of CMC solution decreased with the increase of shear

              rate due to its excellent pseudoplasticity
