Cellulose ether is often an indispensable component in dry-mixed mortars. Because it is an important water retention agent with excellent water retention properties. This water retention property can prevent the water in the wet mortar from evaporating prematurely or being absorbed by the substra...
1.Depending on its own pore structure
Activated carbon is a kind of microcrystalline carbon material which is mainly made of carbonaceous material with black appearance, developed internal pore structure, large specific surface area and strong adsorption capacity.Activated carbon material has a l...
Hydroxypropyl methylcellulose HPMC can significantly improve the water retention of the mortar. When the addition amount is 0.02%, the water retention rate will be increased from 83% to 88%; the addition amount is 0.2 %, the water retention rate is 97%. At the same time,...
How is activated carbon made?
Activated carbon is commercially manufactured from coal, wood, fruit stones (mainly coconut but also walnut, peach) and derivatives of other processes (gas raffinates). Of these coal, wood and coconut are the most widely available.
The product is manufactured by a th...
In ready-mixed mortar, the addition of cellulose ether is very low, but it can significantly improve the performance of wet mortar, which is a major additive affecting the construction performance of mortar. the important role of HPMC in mortar is mainly in three aspects...
The dissolution methods of HPMC include: cold water instant solution method and hot solution method, powder mixing method and organic solvent wetting method
The cold water solution of HPMC is treated with glyoxal, which is rapidly dispersed in cold water. At this time, i...
Air and water pollution remain among the most pressing global issues, putting vital ecosystems, food chains, and the environment necessary for human life in jeopardy.
Water pollutions tend to stem from heavy metal ions, refractory organic pollutants, and bacteria—toxic, ...
