The global average annual output of lubricant additives is relatively stable, with an average annual growth rate of only about 1%.At present, the total production capacity of lubricating oil additives at home and abroad is about 4.5 million tons, and 90%
In order to improve the uniformity of fresh foamed concrete slurry and reduce the temperature difference stress, the following measures are put forward, which can effectively reduce the foam mixing.
Concrete admixtures are essential components of high performance concrete. The selection of admixtures directly affects the functional properties of concrete.However, in order to achieve the expected performance of concrete, it is necessary to understand
Foaming agents play an important role in different fields, such as porous materials, cosmetics, food, fire fighting and oil recovery.There are many kinds of foaming agents, and their performance evaluation indexes are mainly foamability and stability.
The standard of cement foaming agent mainly depends on the foaming times of cement foaming agent and the stabilizing effect of foaming agent. These are the two most important indicators we are looking at right now.
