How does the formation of a cellulose ether film affect mortar performance?

In wet mortar, water starts evaporating. During this process, cellulose ether gathers on the surface, creating a thin film within 5 minutes. This film slows down further evaporation. As more water moves from thick to thin parts of the mortar layer, the initial film partially dissolves. This feature allows more cellulose ether to accumulate on the surface.


The film’s thickness impacts mortar performance:

1. If the film is too thin, it might dissolve again, failing to stop water evaporation and potentially weakening the mortar.


2. If the film is too thick, there’s a lot of cellulose ether in the mortar joints, making it tough to break the surface film when laying tiles.

How does inadequate mixing impact cellulose ethers' quality?

An improper mixture of water, alkali, cotton, and etherification agents impacts the alkali treatment and etherification process.


Insufficient stirring during alkali treatment may lead to alkali crystallization and sedimentation at the equipment’s bottom. Resulting in incomplete alkali treatment and a lower concentration at the upper layer.


So, a significant amount of free alkali may remain after etherification. That will lead to uneven product substitution. Also, it can result in diminished transparency and higher fiber content. It also reduced water retention, lowered gelation point, and increased pH value.

How does cellulose ether affect putty workability?

Cellulose ethers play a crucial role in determining how easy it is to work with putty. When there’s too little cellulose ether, the putty remains too runny. This issue can cause uneven settling on the wall and affect the final performance.


When the cellulose ether content is high, the putty’s viscosity becomes too high. The putty admixture will stick to the trowel and make it hard to smooth the surface during wall construction.


Thus, the right amount of cellulose ether is essential for optimal putty performance.

What Is Cellulose Ether?

Cellulose ether is a modified polymer derived from cellulose. It is the most abundant natural water-soluble polymer on Earth. From thickening to stabilizing, cellulose ether is a key additive in construction, personal care items, and paints. Its unique properties, such as water retention and solubility, ensure it plays a vital role in creating quality products.


Cellulose ether production begins with high-purity cellulose sourced from wood pulp or cotton linters. These natural sources provide the necessary raw material due to their high cellulose content and minimal impurities. The purified cellulose ether is dried and milled into a fine powder. And it is easier to handle and incorporate into various formulations.

What is Carboxymethyl Cellulose (CMC)?

Carboxymethyl Cellulose (CMC) is a cellulose derivative. CMC is the most abundant organic polymer on the Earth. CMC is created by chemically modifying cellulose with carboxymethyl groups. So, it is water-soluble and versatile.


CMC powder is used as a thickener, emulsifier, and stabilizer in various industries. It is also used in the production of paper, adhesives, and oil drilling industries. It can modify the viscosity and flow properties of aqueous solutions.

What is the cellulose ether manufacturing process of WOTAIchem?

WOTAIchem cellulose ethers are produced through alkali treatment. We produce cellulose ether by reacting cellulose with sodium hydroxide and then with an alkyl halide. For example, methyl or ethyl chloride.


You can also refer to our blog post for a detailed description of the cellulose ether manufacturing process.

Does higher viscosity in cellulose ethers result in better water retention? What factors primarily affect the water retention properties of cellulose ethers?

Cellulose ethers’ water retention properties depend on the content of functional groups. Higher functional group content leads to better water retention. However, higher viscosity in cellulose ethers does not result in better water retention. Other factors can also affect water retention properties. For example, the formulation of the mortar or plaster. If you have more questions, feel free to contact our expert now.

Why does cellulose ether sometimes clump in hot weather?

Cellulose ethers can clump in overly humid environments. This can affect their usability. It’s important to note that cellulose ethers can also clump in hot weather regions. If you cannot use the opened cellulose ethers within two months, there is a high risk of clumping.


Please ensure to follow our recommended storage guidelines to mitigate this issue effectively.

What is cellulose ether used for?
Mostly in construction additives. Dry mortar, plaster adhesives, tile adhesives, anti-cracking wall putty, water-proof mortar, and many more. WOTAI cellulose ether has exceptional water-retention properties that significantly enhance the textures and workability of the product. Quality is our foundation. We make sure the end products deliver consistency and stability, as always.
How does Carboxymethyl Cellulose (CMC) relate to your product range of cellulose ethers?

CMC shares the cellulose backbone with our product range. But, it differs in terms of chemical modification and applications. CMC is valued for its water-soluble and thickening properties. Making it a versatile choice in industries such as food, pharmaceuticals, and cosmetics.
