The redispersible latex powder is dispersed and formed into a mold and acts as a second adhesive to enhance the adhesion; the protective colloid is absorbed by the mortar system (it will not be destroyed after the mold is formed. Or twice dispersed); the polymerization of the mold As a reinforcing material, the resin is distributed in the entire mortar system, thereby increasing the cohesion of the mortar.

In the production of putty powder, we need to use redispersible latex powder. Using these latex powders can increase the bonding strength. We know that if we want to produce high-quality putty powder, the formula must be appropriate, and the additives inside must be used appropriate. We use redispersible latex powder to increase the strength, so how can we ensure this strength?

Redispersible latex powder mainly has the effect of toughness and strength in construction projects. Generally, the effect of adding a certain amount of strength will be good, but the following issues should be paid attention to during the use of the product:

Accurately weigh and measure the hydroxypropyl methylcellulose sample. Cover the crucible with a half cap with hydroxypropyl methylcellulose, and calculate the iron salt content: the mass of the plastic iron 1000 is measured for several times,

Hydroxypropyl methylcellulose HPMC cold water (instant type): It is surface treated with glyoxal and quickly dispersed in cold water, but it is not really dissolved, the viscosity comes up, and the aqueous solution becomes clear and transparent. Really dissolved.

1. Air-entraining. Hydroxypropyl methyl cellulose ether hpmc has strong air-entraining properties, while hydroxypropyl starch ether has no air-entraining properties.

Extract 2.0g of hydroxypropyl methylcellulose HPMC sample dried to constant weight into a beaker, add 98ml of 80~90℃ hot water to make a 2.0% (g/g) solution, stir for about 20min, then put in ice Cool in the bath for 50min, continue to mix during the cooling process, remove air bubbles,

The wet-mixed mortar is cement, fine aggregate, additives and water, and various components are determined according to the performance. After measuring and mixing in a certain proportion at the mixing station, the mixture is transported to the place of use in a special container for storage, and the wet mix is ​​used within the specified time.

1. The redispersible latex powder affects the strength of the putty powder. Adding the redispersible latex powder to the putty powder and mortar can increase its strength, and it has a great help in improving the hardness.
