The role of dispersible polymer powder in putty powder
1. Putty is used as a material for pretreatment of the surface to be coated in architectural coatings Putty is a thin layer of leveling mortar. Putty is scraped on the surface of rough substrates (such as concrete, leveling mortar, gypsum board, etc.) Make the exterior wall paint layer smooth and...Read more -
Common applications of dispersible polymer powders
The rubber powder is made of high temperature, high pressure, spray drying and homopolymerization with a variety of active-enhancing micropowders, which can significantly improve the bonding ability and tensile strength of the mortar. , outstanding heat aging performance, simple ingredients, easy...Read more -
Application of Redispersible Polymer Powder in Mortar System
Dispersible polymer powder and other inorganic binders (such as cement, slaked lime, gypsum, etc.) and various aggregates, fillers and other additives (such as methyl hydroxypropyl cellulose ether, starch ether, lignocellulose, hydrophobic Agents, etc.) are physically mixed to make dry-mixed mort...Read more -
The role and precautions of redispersible latex powder
Redispersible latex powder is a powder dispersion obtained by spray drying of modified polymer emulsion. It has good dispersibility and can be re-emulsified into a stable polymer emulsion after adding water. Its chemical properties are exactly the same as the initial emulsion. Therefore, In order...Read more -
Why add hydroxypropyl methylcellulose (HPMC) to gypsum-based mortar
In cement mortar and gypsum-based slurry, hydroxypropyl methylcellulose mainly plays the role of water retention and thickening, which can effectively improve the cohesion and sag resistance of the slurry. Factors such as air temperature, temperature and wind pressure will affect the evaporation ...Read more -
Properties of Hydroxyethyl Cellulose
Hydroxyethyl cellulose It is a non-ionic water-soluble polymer, white or slightly yellow, easy-flowing powder, odorless and tasteless, soluble in both cold water and hot water, and the dissolution rate increases with the increase of temperature. Insoluble in organic solvents. Properties of hydrox...Read more -
Viscosity Properties of Hydroxypropyl Methyl Cellulose
Hydroxypropyl methylcellulose (HPMC) is a non-ionic, water-soluble cellulose mixed ether. Appearance is white to slightly yellow powder or granular material, tasteless, odorless, non-toxic, chemically stable, and dissolves in water to form a smooth, transparent and viscous solution. One of the mo...Read more -
The synthetic method of hydroxypropyl methylcellulose
Generally, in the synthesis of hydroxypropyl methylcellulose, the refined cotton cellulose is treated with alkali solution at 35-40°C for half an hour, squeezed, the cellulose is pulverized, and appropriately aged at 35°C, so that the obtained alkali fibers are averagely polymerized degree is wit...Read more -
HPMC/HPS hot-cold gel blend
Hydroxypropyl methylcellulose (HPMC) film has excellent performance, but because HPMC is a thermal gel, the viscosity at low temperature is too low, which is not conducive to coating (or dipping) and drying at lower temperature to prepare edible film, resulting in poor processing performance; in ...Read more -
The importance of hydroxypropyl methylcellulose (HPMC) for water retention in mortar!
Why is the requirement for water retention in mortar so high, and what are the outstanding advantages of mortar with good water retention? Let me introduce to you the importance of HPMC water retention in mortar! The need for water retention Water retention of mortar refers to the ability of ...Read more -
The role of hydroxyethyl cellulose (HEC) in coatings!
Hydroxyethyl cellulose (HEC), a white or light yellow, odorless, non-toxic fibrous or powdery solid, prepared by etherification of alkaline cellulose and ethylene oxide (or chlorohydrin), belonging to the genus Nonionic soluble cellulose ethers. Because HEC has good properties of thickening, susp...Read more -
Research Progress of Cellulose based Edible Films
1. Cellulose is passed by D-glucopyranose β- A linear polymer formed by the connection of 1,4 glycoside bonds. The cellulose membrane itself is highly crystalline and cannot be gelatinized in water or formed into a membrane, so it must be chemically modified. The free hydroxyl at the positions C-...Read more
