Qualities and safeguards of hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) is really a white colored or gentle yellow-colored, odorless, low-toxic fiber content or powdery sound created from the etherification of alkaline cellulose and ethylene oxide (or chlorohydrin). Nonionic soluble cellulose ether. In addition to thickening. It provides the attributes of suspensions, binding, flotation, movie development, dispersion, drinking water preservation and delivering safety colloids: 1. HEC is soluble in cold or hot water and will not precipitate at higher temperature ranges or boiling, creating an array of solubility and viscosity qualities. Plus it fails to gel by heat 2. Nonionic itself can coexist with a number of other h2o-soluble polymers, surfactants and salts, and is a wonderful colloidal thickener for solutions that contains higher levels of electrolytes 3. Water retention capacity is methyl Double the amount cellulose and has better stream regulating features. 4. Compared with the known methylcellulose and hydroxypropylmethylcellulose, HEC has the most severe dispersing capability, but the strongest defensive colloid capacity. Because HEC has good components of thickening, suspending and dispersing, emulsifying, bonding, movie-forming, moisturizing and delivering protective colloids, it has been widely used in the career fields of gas search, surface finishes, development, treatment and meals, textiles, papermaking and polymer polymerization. Wide range of apps. Safety measures: Ever since the work surface-treated hydroxyethyl cellulose is in natural powder type or cellulose reliable, you can easily deal with and simply must be dissolved in h2o. Notice the next. 1. Before and after introducing hydroxyethyl cellulose, it should be stirred continuously up until the option is completely clear and crystal clear. 2. It needs to be sieved and then slowly applyed to the blending barrel. Do not directly add more the hydroxyethyl cellulose containing established into disables and balls in the blending barrel. 3. Water temperature and pH value are obviously related to the dissolution of hydroxyethyl cellulose, so special focus should be compensated with it. 4. Do not add alkaline substances to the combination before the hydroxyethyl cellulose natural powder is warmed with normal water. Boosting the pH worth after home heating is beneficial to dissolution. 5. Add antifungals as soon as possible. 6. When you use great-viscosity hydroxyethyl cellulose, the concentration of the mom liquor should not be more than 2.5-3%, usually the mother liquor will probably be challenging to process. The handled hydroxyethyl cellulose is often challenging to make lumps or balls, nor can it develop insoluble spherical colloids after introducing drinking water.
