Redispersible latex powder can significantly improve the bonding strength of mortar. The greater the amount of redispersible latex powder, the more redispersible latex powder manufacturers can increase, but the compressive strength of redispersible latex powder decreases, so it can There is an optimal range for the redispersed latex powder. Since the price of redispersible latex powder is higher, the larger the amount, the higher the cost of dry-mixed mortar, so the cost must be considered. The high bond strength has a certain inhibitory effect on the shrinkage, and the stress generated by the deformation of the redispersible latex powder is easy to disperse and release.

Methyl cellulose ether can make the ash (mortar) slurry material obtain suitable water retention and consistency, and effectively improve the workability of the plastering material; at the same time, it can gradually release the water over a long period of time, thereby Ensure the combination of ash (mortar) and base.

Hot water dissolution method: Since HPMC does not dissolve in hot water, HPMC can be uniformly dispersed in hot water at the initial stage, and then quickly dissolved during cooling. Two typical methods are described as follows:

Quick-dissolving hydroxypropyl methyl cellulose ether HPMC is designed for liquid products. The surface of HPMC hydroxypropyl methyl cellulose ether is treated with glyoxal under certain temperature and pH conditions. The hydroxypropyl methyl cellulose ether treated in this way is only dispersed in neutral cold water without swelling and viscosity, which can delay the swelling. At this time, the aqueous solution will be stirred for 5-10 minutes or the When the solution environment (PH value) is adjusted to alkaline, the hydroxypropyl methyl cellulose ether begins to swell to produce viscosity. This type of surface treatment is usually referred to as the instant type.

There are many characteristics and benefits of hydroxypropyl methylcellulose used in building materials. Qingquan Chemical will give you a detailed introduction:
Characteristics of hydroxypropyl methylcellulose

In the recent research on the composition of the internal wall insulation mortar, it is not difficult to find that there is a kind of hpmc that is very common in our lives. Let’s not look at its economic benefits for the time being. First of all, this type of raw material for internal wall insulation mortar has the effect of strengthening the product. So what is hpmc and what is the working principle of product response:

Redispersible latex powder is widely used in the construction industry. It is a very good adhesive and has a very good waterproof function. It is its superior function that makes its scope of use continue to expand, and there are such products in many places.

There are many adhesives in our lives. With the rapid development of social science and technology, the performance of adhesives used today is getting greater and greater. Now there is a product on the market that is very easy to use. It is not only It can be used as an adhesive, and there are other uses. This is redispersible latex powder.

Hydroxypropyl methyl cellulose has good viscosity to wet mortar, can significantly improve the bonding performance between the wet mortar and the base layer, and improve the anti-sagging performance of the mortar. It is widely used in mortar, external wall insulation and surface bonding mortar.
