In the ready-mixed mechanical spraying mortar, the addition of hydroxypropyl methyl cellulose ether is very low, but can significantly improve the performance of wet mortar, mortar construction performance is a major additive. Reasonable selection of cellulose ether with different varieties, different viscosity, different particle size, different viscosity degree and addition amount has a positive effect on the improvement of dry mortar properties.

Hydroxyethyl methyl cellulose HEMC can be used as a colloidal protective agent, emulsifier and dispersant due to its surface activity in aqueous solution. Examples of its applications are as follows:

As we all know, tile adhesive is generally made from cement and mixed with various additives. It is mixed with water at the construction site and then applied to the wall or floor. It generally has a certain initial strength about 12 hours after construction. The strength increases with time and is generally basically stable after 28 days.

After the putty has dried and been de-powdered, the root cause can be attributed to the fact that the bonding system did not work. Why the bonding system, whether it is an inorganic binder or an organic binder, can be considered from the following aspects.

One of the most important applications of polymer-modified cement mortar is the application of thin-layer construction methods to tile. The specific process is as follows: the dry powder adhesive with the package is mixed with water on the spot,

Starch ethers are used in cement-based systems such as plastering, adhesives, and leveling layer to form functional surfaces both internally and externally. Plastering mortar is used to cover uneven parts of walls. They must have a strong and durable bond to the substrate. 

Redispersible polymer powder produced by spray-drying special water-based emulsion, mostly based on vinyl acetate-ethylene (VAE), and then obtained a free flowing organic polymer powder. It can re-disperse in water, and form a film after water evaporation by coalescence of individual polymer particles.

What should I pay attention to when using hydroxypropyl methylcellulose?

The hydroxypropyl methylcellulose market continues to expand. Compared with European malls, China’s hydroxypropyl methylcellulose mall is still in its infancy. Whether it is production skills or equipment, it is relatively backward, as a new type of Industry,
