MHEC/HEMC Product is packed in three layer paper bag with interior polyethylene bag bolstered , Web body weight is 25kg for each bag.
MHEC is derived from hydroxyethylcellulose, a drinking water-soluble polymer acquired by reacting ethylene oxide with cellulose.
1. Begin by agitating drinking water comprehensively to be certain uniformity in the solution. Gradually introduce MHEC to the agitated h2o to avoid the formation of lumps.
It's modified with hydroxyethyl and methyl teams, maximizing its solubility and operation. HEMC acts like a thickening agent, enhances h2o retention, and is particularly widely used in a variety of industries due to its adaptable Houses.
Expensive Customers and Companions, be sure to kindly Observe that we do NOT have any offices or agents exterior China. You should Check out with our corporation ahead of processing any organization activities.
This is particularly helpful in scorching and dry climates where immediate humidity reduction can hinder the applying and curing course of action.
MHEC is commonly made use of to be a rheology modifier in cementitious resources including mortars, grouts and self-leveling compounds.
MHEC chemical hydration time counts within the Preliminary wetting to the MHEC Bulk Sale second when the answer begins to be viscous. Hydration time may be varied to satisfy a special prerequisite. MHEC hydration time, apparently afflicted from the pH benefit.Usually ranges from four to 25 minutes.
Among the these cellulose ethers, methyl cellulose and hydroxypropyl methyl cellulose have larger h2o retention.
Enhanced Rheological Properties: MHEC can modify the move Homes of liquids, which makes it useful in purposes check here like paints and coatings, the place it can help reach the desired viscosity and software traits.
Also, its film-forming qualities contribute to your development of a protecting layer, improving the resistance of resources to environmental components and ensuring extensive-phrase structural integrity.
The related read chemical composition of MHEC mirrors that of HPMC. It encompasses hydroxyethyl groups connected to the hydroxyl teams in cellulose. The degree of substitution (DS) governs the quantity of hydroxyethyl teams incorporated, influencing MHEC's solubility, viscosity, and various intrinsic traits. MHEC stays secure under conventional problems and displays resistance to microbial degradation.
Particular apps may have to have diverse viscosity grades of HEMC. For instance, decreased viscosity grades may be Utilized in purposes the place lower thickening is necessary, even though greater viscosity grades are employed when larger thickening and movie-forming Qualities are expected. The exact viscosity grade must be picked out depending on the necessities of the particular software.
Diminished Sagging: MHEC aids avoid sagging and slumping of construction components, for instance vertical wall coatings and renders. This makes sure that the utilized content stays in position as intended.
