What is the function of redispersible polymer powder?
The film of redispersible polymer powder RDP is elastic and tough, in the rigid skeleton formed by the hydration of cement mortar. Between the particles of the cement mortar, it functions like a movable joint, which can bear high deformation loads, reduce the stress, and improve the tensile and b...Read more -
Ash content standard for redispersible polymer powder
The ash content from the regular redispersible polymer powder factory is generally 10±2 The ash content standard is within 12%, and the quality and price are comparable Some domestic latex powders are more than 30%, and even some rubber powders have as much as 50% ash. Now the quality and price o...Read more -
Application of dispersible polymer powder in tile adhesive
Re-Dispersible polymer powders are spray-dried emulsions that, when mixed with water or water in a mortar, form the same stable dispersion as the original emulsion. The polymer forms a polymer network structure in the mortar, which is similar to the polymer emulsion properties and modifies the mo...Read more -
Application and function of redispersible polymer powder
Redispersible polymer powder is mainly used in: internal and external wall putty powder, tile adhesive, tile grout, dry powder interface agent, external thermal insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar, etc. in dry mortar. It is a powder dispers...Read more -
Dispersible polymer powder
1.Product introduction Name: VAE dispersible latex powder Packing: 25kg/bag The redispersible latex powder product is a water-soluble white or off-white flowable powder, which is a copolymer of ethylene and vinyl acetate, and uses polyvinyl alcohol as a protective colloid. Due to the high binding...Read more -
Basic knowledge of dispersible polymer powder
1. basic concept Redispersible polymer powder is the main additive for dry powder ready-mixed mortar such as cement-based or gypsum-based. Redispersible latex powder is a polymer emulsion that is spray-dried and aggregated from the initial 2um to form spherical particles of 80~120um. Because the ...Read more -
Hydroxypropyl methylcellulose HPMC
Hydroxypropyl methyl cellulose, also known as hypromellose, cellulose hydroxypropyl methyl ether, is obtained by selecting highly pure cotton cellulose as raw material and specially etherified under alkaline conditions. Widely used in construction, chemical, pharmaceutical and other industries. c...Read more -
What factors affect the water retention of hydroxypropyl methylcellulose
The higher the viscosity of hydroxypropyl methylcellulose, the better the water retention performance. Viscosity is an important parameter of HPMC performance. At present, different HPMC manufacturers use different methods and instruments to measure the viscosity of HPMC. The main methods are Haa...Read more -
Popularization of hydroxypropyl methylcellulose HPMC knowledge
Hydroxypropyl methylcellulose HPMC is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processing. They are an odorless, tasteless and nontoxic white powder that swells in cold water to a clear or slightly hazy colloidal solution. It has the pr...Read more -
Relationship between Viscosity and Temperature of Hydroxypropyl Methylcellulose (HPMC)
(1) Determination of HPMC viscosity: The dried product is prepared into an aqueous solution with a weight concentration of 2 °C, and is measured by an NDJ-1 type rotational viscometer; (2) The appearance of the product is powder, and the instant product is suffixed with “s” in the bra...Read more -
Hydroxypropyl methyl cellulose in machine spray mortar
With the wide use of mortar, the quality and stability of mortar can be well guaranteed. However, since the dry-mixed mortar is directly processed and produced by the factory, the price will be higher in terms of raw materials. If we continue to use manual plastering on site, it will not be compe...Read more -
HPMC used in construction industry
As a common building material, hydroxypropyl methylcellulose HPMC is more important in the construction industry. What are the main functions of hydroxypropyl methylcellulose? 1. Masonry mortar Enhanced adhesion to the masonry surface and can enhance water retention, thereby increasing the streng...Read more
