Recently, Dow Chemical Europe Limited announced force majeure, with immediate effect. It is suitable for all polyether polyols containing ethylene oxide (EO). The influence devices are temeuzen in the Netherlands and Tertre in Belgium.EO production has been interrupted due to accidents and unforesee
The commonly used surfactants are low molecular weight compounds with molecular weight of several hundred. With many hot areas, such as enhanced enhancedoil recovery, drug carrier and controlled release, biological simulation, polymer LB membrane, medical polymer materials (anticoagulant), emul
What's the difference between wetting and penetration of surfactant? Drop a drop of water on a clean glass surface, and the water drops will quickly spread on the glass surface.
When the daily average outdoor temperature is stable below 5 ℃ for 5 consecutive days, the winter construction will be started; when the daily average outdoor temperature is higher than 5 ℃ for 5 consecutive days, the winter construction will be terminated. The following matters should be paid atten
Concrete slump is mainly refers to the plasticizing properties of concrete and its pumpability. Main influencing factors of concrete slump are: graded change, water content, weighing deviation and dosage of admixtures, the temperature of the concrete is very easy to be ignored. By adding concrete polycarboxylate superplasticizer can greatly improve concrete slump and workability.
Surfactant is a very special chemical substance. It is widely used in cosmetics industry. It is an auxiliary material for cosmetic materials. Although it is not used in a large quantity, it plays a great role in the application of most products such as cleansing cream, moisturizing lotion
