What are the different types of dry mortar? The application of redispersible latex powder
Dry powder mortar refers to a granular or powdery material formed by physical mixing of aggregates, inorganic cementitious materials, and additives that have been dried and screened in a certain proportion. What are the commonly used additives for dry powder mortar? Dry powder mortar generally us...Read more -
What effect water-retaining property of cellulose ether?
Generally speaking, the viscosity of hydroxypropyl methylcellulose is higher, but it also depends on the degree of substitution and the average degree of substitution. Hydroxypropyl methylcellulose is a non-ionic cellulose ether with a white powder appearance and no Odorless and tasteless, solubl...Read more -
What is hydroxyethyl methyl cellulose (HEMC)?
What is hydroxyethyl methyl cellulose (HEMC)? Hydroxyethyl methylcellulose (HEMC) is also known as methylhydroxyethyl cellulose (MHEC). It is a white, grayish white, or yellowish white particle. It is a non ionic cellulose ether obtained by adding ethylene oxide to methyl cellulose. It is made f...Read more -
What is methyl cellulose ether used for? How is cellulose ether made?
Cellulose Ether – Thickening and Thixotropy Cellulose ether endows wet mortar with excellent viscosity, which can significantly increase the adhesion between wet mortar and base layer, improve the anti flow performance of mortar, and is widely used in plastering mortar, ceramic tile bondin...Read more -
What is redispersible emulsion powder used for?
Redispersible emulsion powder is the dispersion of polymer lotion after spray drying. With its promotion and application, the performance of traditional building materials has been greatly improved, and the bonding strength and cohesion of the materials have been improved. It can improve the perf...Read more -
What construction additives can improve the properties of dry mixed mortar? How do they work?
The anionic surfactant contained in construction additives can make the cement particles disperse each other so that the free water encapsulated by the cement aggregate is released, and the agglomerated cement aggregate is fully diffused and thoroughly hydrated to achieve a dense structure and in...Read more -
Elaborate on the historical development process of redispersible latex powder and ceramic tile adhesive
As early as the 1930s, polymer binders were used to improve the performance of mortar. After the polymer lotion was successfully put on the market, Walker developed the spray drying process, which realized the provision of lotion in the form of rubber powder, becoming the beginning of the era of ...Read more -
Redispersible latex powder is a kind of powder adhesive made by special lotion spray drying.
Redispersible latex powder is a kind of powder adhesive made by special lotion spray drying. This kind of powder can be quickly dispersed into lotion after contacting with water, and has the same properties as the initial lotion, that is, the water can form a film after evaporation. This film has...Read more -
What are the functions of redispersible polymer powder in different drymix products? Is it necessary to add redispersible powder in your mortars?
Redispersible polymer powder has a wide range of applications. It is playing an active role in wider and wider applications. Like ceramic tile adhesive, wall putty and insulation mortar for exterior walls, all have close relations to redispersible polymer powder. The addition of redispersible la...Read more -
The role and advantages of redispersible latex powder，This not only avoids errors during mixing at the construction site, but also improves the safety of product handling.
The function of redispersible latex powder: 1. The dispersible latex powder forms a film and serves as an adhesive to enhance its strength; 2. The protective colloid is absorbed by the mortar system (it will not be damaged by water after film formation, or “secondary dispersion”; 3...Read more -
Soldissolved hydroxypropyl methyl cellulose HPMC in wet mortar
Soluble hydroxypropyl methyl cellulose (HPMC) is a kind of non-ionic cellulose ether, which is made from natural polymer cellulose through a series of chemical processing. Hypromellose (HPMC) is a white powder that dissolves in cold water to form a transparent, viscous solution. It has the proper...Read more -
Effect of viscosity of cellulose ether on properties of gypsum mortar
Viscosity is an important property parameter of cellulose ether. Generally speaking, the higher the viscosity, the better the water-retaining effect of gypsum mortar. However, the higher the viscosity is, the higher the molecular weight of cellulose ether is, and the solubility of cellulose ether...Read more
