Hydroxypropyl methyl cellulose in dry mortar (mortar), the addition of cellulose ether is very low, but it can significantly improve the performance of wet mortar. Mortar is the main additive that affects construction performance. The redispersible latex powder product is a water-soluble white or almost white flowable powder, a copolymer of ethylene and vinyl acetate, and polyvinyl alcohol as a protective colloid.

Redispersible latex powder is commonly used in building construction, and sometimes it will encounter cracking. If this problem occurs, how should we deal with it? The following mortar powder manufacturer will give a specific introduction. The film of the product is elastic and tough, in the rigid framework formed by the hydration of the cement mortar.

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.

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.

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:
