Hydroxy Ethyl Cellulose (HEMC)
Purity: 90% HEC Loss on drying ,%: 7 ~ 9 D.S.: 5.0max With advantage of CMC&HEC High viscosity High water-binding capacity Good flocculating action More compatible than CMC Introduction HECMC is a kind of modified water-soluble cellulose ether with the advantage of both carboxymethyl cellulose (CMC) and hydroxyethyl cellulose (HEC) because of the presence of the nonionic hydroxyethyl groups. 1, High water-binding capacity and good flocculating action on suspended solids just like CMC, and more compatible than CMC with salts. 2, Higher viscosity because of its superior capability to cross-link with multivalent cations. 3, It can be easily gelled by cross-linking with cations such as iron, aluminum, chromium to supply an efficient media for suspending particulate matter. Application: 1 Oil-recover: HECMCs have excellent ability to control over fluids containing high salinity and also can effectively reduce water loss in cement slurries 2 Fracturing fluids: suitable for suspending and transporting sand or other particulate into a well bore and the fracture. |
