When the temperature on the mortar exceeds forty°C, the h2o retention of methyl cellulose decreases considerably, which adversely influences the workability with the mortar.
KimaCell® MHEC MH400 methyl hydroxyethyl cellulose is applied being an additive for cement compositions. MHEC can be utilized like a multipurpose additive to avoid and/or Management gas channeling, control fluid decline, limit no cost move, make improvements to slurry stability and/or stabilize foam.
Methyl hydroxyethyl cellulose (MHEC) can be employed as an additive in cement slurry in very well treatment to forestall or reduce the incidence of gas channeling. Together with acting being a gas Management additive, methyl hydroxyethyl cellulose controls fluid loss, minimizes cost-free fluid and stabilizes foam during cementing.
It can be modified with hydroxyethyl and methyl groups, improving its solubility and features. HEMC functions being a thickening agent, increases h2o retention, and is particularly broadly used in many industries on account of its flexible properties.
Note: The product is packaged in polypropylene woven luggage, Each and every having a Web weight of 25kg. When storing, area inside of a ventilated and dry location indoors, concentrate to moisture. Concentrate to rain and Sunlight safety in the course of transportation.
The viscosity of HPMC is inversely proportional to temperature, meaning that viscosity raises as temperature decreases. Whenever we refer to the viscosity of a particular product, it commonly refers to the measurement result of its two% drinking water Alternative at 20 levels Celsius.
This informative article requires an in-depth think about the Houses of MHEC and its wide selection of programs across a variety of industries. From construction to prescribed drugs, MHEC reveals special properties that make it a flexible product with multiple uses.
For the planning of aqueous methods that contains MHEC, the subsequent advised course of action needs to get more info be adopted:
This assets is advantageous in applications wherever publicity to superior temperatures is expected, for instance in construction components or industrial processes.
The powder decline in putty is especially connected with the caliber of the lime powder and has minimal to try and do with HPMC. Lower calcium articles in lime powder and an incorrect ratio of CaO and Ca(OH)two in check here lime powder can both of those lead to powder reduction.
These properties make HEMC extensively Utilized in cement mortars, MHEC for the construction industry gypsum products, and tile adhesives from the construction industry.
We've chosen the most common queries that our prospects have requested in past times, to ensure that we provide the ideal methods and assistance for you.
