Various Applications of Cellulose Ethers in Construction Chemicals

There are different types of cellulose ethers for different applications. We introduce you to its various applications in construction chemicals such as tile adhesives, putty, caulking mortars. And the benefits it brings to us.

 

 

Tile adhesive (CTA)

Tile as a functional decorative material has been widely used worldwide. How to paste such a durable material so that it is safe and durable has been a concern. The emergence of wall putty has ensured the reliability of tile adhesive to a certain extent.
With the development of tile adhesive technology and the improvement of construction process, the thin-paste method is also gradually adopted. With this construction method, tiles have better wetting ability and longer open time. In general, the use of different types of cellulose ethers allows the tile adhesive to achieve the appropriate workability and constructability.

 

 

Insulation system

Hydroxypropyl methyl cellulose is an indispensable additive for exterior insulation system, which plays the role of thickening and water retention. Hydroxypropyl methyl cellulose can greatly improve the bond strength of mortar. High water retention can make the cement have a longer fitting time to fully hydrate, and at the same time, it can appropriately increase the tensile strength and shear strength, greatly improve the construction effect and work efficiency.
Hydroxypropyl methylcellulose provides good edge adhesion, low shrinkage and high abrasion resistance, allowing the slurry to adhere firmly to the surface. Hydroxypropyl methylcellulose is essential in exterior wall insulation systems.

 

 
Putty

Putty is a thin layer of plastering material that plays an important role in the decorative and functional aspects of a building. The three layers of decoration are divided into: base wall, putty leveling layer and finish layer, which have different main functions.
When the ambient temperature and humidity change, the deformation of the three layers differs, which requires the putty and finish layer materials to have appropriate modulus of elasticity and rely on their own elasticity and flexibility to eliminate concentrated stress and thus resist cracking of the base and prevent peeling of the finish layer. A quality putty should have good base wetting, recoating and smooth scraping properties.

 

 

Caulking mortar

As an important part of tile paving project, caulking not only improves the overall effect and contrast of tile veneer project, but also plays an important role in improving the waterproof and impermeable performance of the wall.
A good tile adhesive product, in addition to rich color, uniformity and no color difference, should also have the characteristics of easy operation, fast strength, low shrinkage, low porosity and waterproof impermeability, etc. TANGPENG's cellulose ether can reduce shrinkage while providing excellent handling performance for the embedded products.

 

 

Gypsum mortar

Among gypsum-based products, whether plaster plaster, caulk, putty, gypsum-based self-leveling, gypsum-based insulation mortar, cellulose ether plays an important role.
The right cellulose ether is insensitive to the alkalinity of gypsum and can quickly penetrate into gypsum products without caking. HPMC does not affect the formation of gypsum crystals and provides the right wet adhesion to the mixture to ensure the bonding ability of the material to the substrate; it also greatly improves the plaster properties of gypsum products and can be easily spread without the need for a pasting tool.
