hydroxyethyl cellulose oil drilling grade Brief introduction Hydroxyethyl Cellulose is a series of non-ionic soluble cellulose ether, which can be dissolved in hot or cold water. It has the characteristics of thickening, suspending, adhesive, emulsion, film coating and super absorbent polymers protective colloid. It is widely used in paints, cosmetics, oil drilling and other industries.
♦Coating Industry Application Guide High thickening effect Provides excellent coating performance for the latex coating, especially the high PVA coating. There is no flocculation when the paint is thick paste. Has a higher effect of thickening, can reduce the dosage to improve the economic effectiveness of formulation, while improving the washability of the coating. Excellent rheological properties Our product's aqueous solution is non-Newtonian system, the performance that the solution has is called thixotropy. After the product is dissolved completely in stationary state, the coating system will remain the best thickening status and open-cans state. In the tilting state, the system will remain moderate viscosity, make the product equipped with excellent flowability, and do not splash. During brushing and roller coating, the product is easy to spread on the taste material, that will facilitate the construction. At the same time, have an excellent property of anti-splash. Finally, when the paint coating is completed, the viscosity of the system restore immediately, the coating will be sagging at once. Dispersion and solubility Our product HEC is dissolved after a delay in processing, in the case of dry powder added, can effectively prevent caking. Ensure that HEC powder begin to hydration after fully dispersed. After proper surface treatment, it can adjust the dissolution rate and viscosity increasing speed well.
Storage stability Has good bio-stability, provide sufficient time for the paint store. Effectively prevent pigments and sedimentation. ♦♦Application Guide for the cosmetics industry Cosmetics grade Bm Hydroxyethyl Cellulose has good bio-stability, system thickening and rheology modification function, good water retention, film formation, to give the final product full of visual effects and all the necessary application performance. Bm Hydroxyethyl Cellulose after refining can minimize the residual solvent and residual on ignition. After surface treatment , the Bm Hydroxyethyl Cellulose has cold water soluble. Dry powder can be used directly to water. Good dispersion of the product in water avoid the product knot groups, dissolved uneven happen. Final solution uniform, continuous and full. Bm Hydroxyethyl Cellulose not only provide the necessary thickening effect and rheological properties, but also has good color acceptance.
♦♦♦Application in oilfield cementing and drilling industry Hydroxyethyl Cellulose thickening agent can be used as thickener of the well workover fluid and cementing agent. Help to provide clarification of the low fixed content solution, thus greatly reducing the structural damage to the wells. The liquid thickening by Hydroxyethyl Cellulose can be easily decomposed by acids, enzymes oroxidants, greatly improving the ability to recover hydrocarbons. Ruid in the well, Hydroxyethyl Cellulose is used as proppant carrier. These liquids can be easily cracked through the process. Drilling fluid used Hydroxyethyl Cellulose configuration, based on its low solids content, can effectively increase drilling stability. These properties can be used to inhibit the fluid medium to high hardness of the rock and heavy shale or shale drilling. Operations on cement reinforcement, Hydroxyethyl Cellulose slurry can reduce the hydraulic friction, minimize the loss of rock and water loss.
