As a non-ionic surfactant, hydroxyethyl cellulose has the following properties in addition to thickening, suspending, bonding, floating, film-forming, dispersing, water retention and providing protective colloid. Hydroxyethyl cellulose (HEC we all It is known that both hydroxyethyl cellulose HEC and hydroxypropyl methyl cellulose HPMC are used in building materials, but what is the difference between these two raw materials?

There are a lot of resin powders on the market, high-strength water-resistant?polymer powders and other cheap rubber powders to replace the traditional VAE emulsion (vinyl acetate-ethylene copolymer) and spray-dried redispersible latex powder, then the resin What is the difference between rubber powder and redispersible latex powder? Can resin powder replace redispersible latex powder?

Construction mortar is a building material with a large amount of use and a wide range of uses in industrial and civil buildings. There are two forms of on-site preparation and commercialization of construction mortar. At present, the degree of commercialization of mortar in developed countries in Europe and the United States is already very high. This is because dry-mixed bagged or bulk mortar can speed up the turnaround time of the construction site and reduce labor costs. Adapt to the base and materials Variations in varieties improve construction quality and protect the environment. In contrast to mortars that are mixed on site, dry-mix mortars are produced by mixing all necessary components, such as cementitious material aggregates and chemical additives, under strictly controlled conditions for a specific product in a dry-mix mortar factory.

Containing M as a treatment agent for drilling mud and flushing fluid, it can resist the pollution of various soluble salts. The mud containing M is rarely affected by mold, so it is not necessary to maintain a high pH value and use preservatives. Drilling mud and other suspensions and dispersions have a certain shelf life, adding M can make it stable and prolong the shelf life.

Hydroxyethyl cellulose (HEC) is a non-ionic cellulose ether made from natural polymer material cellulose through a series of etherification. It is an odorless, tasteless and non-toxic white powder or granule, which can be dissolved in cold water to form a transparent viscous solution, and the dissolution is not affected by the pH value. It has the characteristics of thickening, adhesion, dispersion, emulsification, film-forming, suspension, adsorption, surface activity, water retention and salt resistance. Widely used in paint, construction, textile, daily chemical, paper, oil drilling and other industries.

Redispersible latex powder products are water-soluble redispersible powders, which are divided into ethylene/vinyl acetate copolymers, vinyl acetate/tertiary carbonic acid ethylene copolymers, acrylic acid copolymers, etc., and powder adhesives made after spray drying. Polyvinyl alcohol was used as a protective colloid. This kind of powder can quickly redisperse into emulsion after contacting with water. Due to the high bonding ability and unique properties of redispersible latex powder, such as water resistance, construction and heat insulation, etc., their application The scope is extremely broad
