Hydroxypropyl methyl cellulose in concrete dosage

When we use it for concrete, this is a question we will consider. Let cellulose manufacturer analysis for you today.

When the content is less than 0.05%, its participation can significantly improve the fluidity and viscosity of foamed concrete slurry.

After dissolution, a wet flexible film is formed between solid particles and gas bubbles, which has excellent smooth effect in the mixing process. This also allows the bubbles to become self-aligned “balls” in the slurry during impossible disillusionment, which effectively improves the fluidity of the fresh slurry.

However, if the dosage amount exceeds 0.5%, the slurry will become too sticky and the fluidity will be greatly reduced. Therefore, the 0.05% content not only ensures slump, but also stabilizes bubbles, which is the amount inhaled.

The content of hydroxypropyl methyl cellulose in concrete is introduced here. If you want to learn more about its applications, you can consider our inquiry.

What are the benefits of using hydroxypropyl methyl cellulose?

Hydroxypropyl methyl cellulose, also known as HPMC, has many applications in our life. At the same time, there are many, many uses for it. Let’s look at the advantages of using hydroxypropyl methyl cellulose today.

HPMC is used as raw material substrate to produce oil, which can realize the utilization of all sugars, improve the utilization rate of raw materials, reduce the substrate residues in fermentation liquid, and reduce the cost of wastewater treatment. This hydroxypropyl methyl cellulose feature favors batch production, optimizes feeding batch and continuous fermentation processes to avoid a number of problems, such as controlling medium composition and dilution rates; This is also beneficial to the regulation of fermentation process. Because the properties of hydroxypropyl methyl cellulose (HPMC) are similar to other water-soluble ethers, it can be used as film forming agent, thickener, emulsifier, stabilizer and so on in latex paint and water-soluble resin paint components. The film has good wear resistance, uniform coating and adhesion, and improved surface tension, stability to acids and bases, and compatibility with metal pigments.

HPMC has good effect as thickener of white water based polyvinyl acetate coating. Cellulose ether has increased degree of substitution and resistance to bacterial attack.
