HPMC in Light Concrete Foamed Concrete
Light concrete /Foamed concrete is a new type of building energy-saving and environmentally friendly material that contains a large number of uniformly distributed closed pores and is very light, heat-resistant, moisture-proof and sound-proof, and is particularly suitable for exterior wall insulation systems of buildings. It can be seen from this that to slow down the various characteristics of foam concrete, its additives must have these properties.
Therefore, as the most important raw material of foamed concrete, hydroxypropyl methylcellulose is a building material with high water retention, high temperature resistance and strong adhesion.
As far as the current production technology is concerned, many closed pores in foamed concrete do not exist naturally, but are formed by putting raw materials such as hydroxypropyl methyl cellulose into the mixing equipment and mixing them for a long time. This kind of closed pores effectively solves the phenomenon of excessive waste of filling materials and saves costs to a large extent. Some people may ask if there is no such effect without adding hydroxypropyl methylcellulose? I can tell you with certainty, yes. Due to the special properties of hydroxypropyl methylcellulose, it can make various raw materials fit together well, so that they can produce a special bonding force, and increase its tensile and anti-extrusion ability.
