This article continues to introduce the application of hydroxyethyl cellulose (HEC)
●Cosmetics and detergents
HEC is an effective film former, binder, thickener, stabilizer and dispersant in shampoos, hair sprays, neutralizers, hair conditioners and cosmetics. Its thickening and protective colloid properties can be used in liquid detergent and solid detergent industries. HEC dissolves quickly at high temperature, which can speed up the production process and improve production efficiency. As we all know, the obvious feature of detergents containing HEC is that it can improve the smoothness and mercerization of fabrics.
HEC with a certain molar substitution degree can play a role in the process of catalyzing protective colloid polymerization; HEC can play a role in controlling the growth of polymer particles, stabilizing latex performance, low temperature and high temperature resistance, and mechanical shear resistance. Effect. During the polymerization of latex, HEC can protect the concentration of colloid within a critical range, and control the size of polymer particles and the degree of freedom of participating reactive groups.
HEC has viscosifying properties in processing and filling mud. It helps provide good low solids mud with minimal damage to the wellbore. Mud thickened with HEC is easily degraded into hydrocarbons by acids, enzymes or oxidants and can maximize oil recovery.
In cracked mud, HEC can play the role of carrying mud and sand. These fluids are also easily degraded by the above acids, enzymes or oxidizing agents.
HEC can be used to prepare ideal low solid phase drilling fluid, which provides greater permeability and better drilling stability. Its fluid-inhibiting properties can be used in the drilling of hard rock formations, and it is also suitable for drilling in collapsed or slide-slumped formations.
In the operation of adding cement, HEC reduces the friction of the pore-pressed cement slurry, thereby minimizing the damage to the structure caused by the loss of water.
