<< APPLICATION TIPS
Polyethylene oxide (PEO) applications (2)

(8) Dust reducer
In the concrete or mortar spraying construction will produce dust, so that the operating environment is greatly deteriorated, if you add a dust reducer in the mixed cement, you can make the spray produce very little dust, will not cause the spray nozzle clogging, also Does not reduce the strength of the cement.
(9) Textile Additives
In recent years, with the increase of textile productivity, the speed of textile machinery has greatly increased. It has increased from 1000-1500 m/min to 3500-7000 m/min. As the speed of the vehicle increases, a large amount of oil splashes are caused, causing the operation. The deterioration of the environment has brought many problems to the safety of the operation work and the economical production. In addition, fiber fluffing has also been caused.
Adding PEO to textile oils originally used to make aqueous emulsion-based textile oils can overcome these disadvantages. The amount of PEO used is generally 0.4-1% of fiber weight (varies with fiber type, morphology, etc.).
In addition, if PEO is added to polyolefins, polyamides, and polyesters, the dyeing and antistatic properties of these fibers can be significantly improved by melt spinning.
(10) Soil stabilizer
PEO can form water-insoluble association complexes with polyacrylic acid, which is the basis for stabilizing the soil and preventing erosion of hillside and riparian soils. It is spraying a 1% concentration of apportioned PEO solution on the soil. The amount is about 0.45 kg/m2, and then the sprayed amount of polyacrylic acid at a concentration of 10-20% is about 0.27 kg/m2. Although the resulting associate is insoluble in water, it is permeable to water. The thickness of the soil coating can increase the number of repeated sprays as needed.
(11) Cleaning agent
The use of PEO can increase the function of many industrial cleaning agent formulations. It can be combined with organic acids (such as citric acid, oxalic acid, etc.), inorganic acids (such as phosphoric acid, hydrochloric acid, etc.), ammonium hydroxide, surfactants, etc. Formulations can greatly increase the viscosity of cleaning agents and control the fluidity of these cleaning agents to suit various applications.
(12) Liquid detergent
Liquid detergents containing PEO produce lubricious and thick foams that leave a smooth, soft feel to the skin. These are characteristics that PEO-free liquid detergents do not have and PEO concentrations are required in liquid detergents. Very low, usually 0.05-0.1% by weight, often using low molecular weight PEO with a narrow molecular weight distribution because they do not make the liquid detergent too sticky.
The above is just a few hundred applications from PEO. Some of them are introduced for your reference. PEO applications are basically blank in China except for very few aspects (such as papermaking, building materials, etc.), so the application research of PEO is ours. One of the important work directions in the future.
