Hydroxyethyl cellulose and ethyl cellulose
1. Basic concepts Hydroxyethyl cellulose (HEC): Hydroxyethyl cellulose (HEC) is a natural polymer compound, usually obtained by etherification of cellulose. The hydroxyethyl (–CH2CH2OH) group is introduced into its molecule, giving it good water solubility, thickening, gelling and surface activit...Read more -
Using HEC Ethyl Cellulose to Thicken Liquid Soap
Ethyl Cellulose (EC) is a chemically modified cellulose derivative widely used in cosmetics, pharmaceuticals, foods and daily chemicals, especially in the thickening of liquid soap. Liquid soap is a common cleaning product, mainly composed of surfactants, water and some thickeners, moisturizers a...Read more -
Dissolution method and main uses of ethyl cellulose
1. Dissolution method of ethyl cellulose Ethyl cellulose (EC) is a chemical made by ethylating natural cellulose, which has good biocompatibility, non-toxicity and degradability. Because its structure contains a large number of hydroxyl and ethyl groups, it has certain challenges in dissolving. I...Read more -
Analysis of water resistance principle of redispersible latex powder type putty
Redispersible latex powder and cement are the main bonding and film-forming substances of water-resistant putty. The water-resistant principle is: During the mixing process of redispersible latex powder and cement, the latex powder is continuously restored to the original emulsion form, and the l...Read more -
The mechanism of action of dispersible polymer powder in dry mortar
Dispersible polymer powder and other inorganic adhesives (such as cement, slaked lime, gypsum, clay, etc.) and various aggregates, fillers and other additives [such as hydroxypropyl methylcellulose, polysaccharide (starch ether), fiber Fiber, etc.] are physically mixed to make dry-mixed mortar. W...Read more -
The difference between dispersible polymer powder and resin powder
In recent years, a lot of resin rubber powder, high-strength water-resistant rubber powder and other very cheap rubber powder have appeared on the market to replace the traditional VAE emulsion (vinyl acetate-ethylene copolymer), which is spray-dried and recyclable. Dispersible latex powder, then...Read more -
Influence of dispersible polymer powder on cement-based materials
Redispersible latex powder is a commonly used organic gelling material. It is a powder obtained by spray drying a polymer emulsion with polyvinyl alcohol as a protective colloid. This powder can be re-dispersed in water evenly after encountering water. , forming an emulsion. The addition of dispe...Read more -
Redispersible polymer powder of dry mix mortar additives series
