KimaCell® MHEC MH400 methyl hydroxyethyl cellulose is used as an additive for cement compositions. MHEC can be used as a multipurpose additive to circumvent and/or Command fuel channeling, Regulate fluid reduction, reduce totally free movement, enhance slurry stability and/or stabilize foam.
Methyl hydroxyethyl cellulose (MHEC) can be utilized being an additive in cement slurry in perfectly therapy to forestall or reduce the event of fuel channeling. In addition to acting for a fuel Manage additive, methyl hydroxyethyl cellulose controls fluid reduction, minimizes no cost fluid and stabilizes foam throughout cementing.
From the context of oil drilling and extraction, significant-viscosity MHEC powder is principally applied for a thickening agent in drilling and completion fluids. Very low-viscosity MHEC is applied for a fluid decline reducer. MHEC powder serves for a thickening agent in several drilling, completion, cementing, and fracturing fluids, guaranteeing that mud has very good flowability and security.
Chemical modification involves the introduction of varied useful teams in to the cellulose backbone, transforming its properties.
This is particularly valuable in incredibly hot and dry climates where speedy humidity loss can hinder the appliance and curing system.
Melacoll�?gives several different HEMC grades and custom-made formulation products and services to satisfy the requires of varied industries.
In the actual situations of industrial apps, shear amount is a related read crucial factor to contemplate when the quantity of Hydroxyethyl methyl cellulose MHEC needed to reach a specific viscosity. Generallyspeaking, the higher the shear price, the reduced the viscosity.
The related read gelation temperature of HPMC is linked to its methoxy content material. The decreased the methoxy content material, the upper the gelation temperature. Tags
Enhanced Open up Time: In construction and tiling apps, MHEC extends the open up time on the adhesive or mortar. This permits staff additional the perfect time to place tiles or do the job with the material ahead of it starts to set.
Constructing Quality Methyl Hydroxyethyl Cellulose (MHEC) is a flexible non-ionic cellulose ether commonly used during the construction industry. This white powder or granule, noted for its odorless and tasteless mother nature, is synthesized via a number of etherifications.
The chemical construction of MHEC mirrors that of HPMC. It encompasses hydroxyethyl teams linked to the hydroxyl teams within cellulose. The diploma of substitution (DS) governs the amount of hydroxyethyl groups included, influencing MHEC's solubility, viscosity, as well as other intrinsic attributes. MHEC remains steady less than normal disorders and exhibits resistance to microbial degradation.
Precise apps may perhaps demand different viscosity grades of HEMC. By way of example, lower viscosity grades could possibly be used in programs in which lower thickening is needed, while better viscosity grades are made use of when greater thickening and get more info film-forming Qualities are essential. The exact viscosity quality need to be chosen based upon the necessities of the particular application.
MHEC is better efficiency with regard to bigger gel temperature and hydrophilicity rely upon ethyl substituent groups.
