Building-grade cellulose ether is an important building additive and is widely used in construction projects. It is mainly produced by chemical modification of cellulose in plant fibers and has the characteristics of high molecular weight compounds. Building-grade cellulose ether is mainly used in building materials such as cement, mortar, coating, dry mortar, etc., which can improve the performance of these building materials and improve their use effect.
1. Thickening and water retention of cement mortar
In cement mortar, cellulose ether, as a thickener and water retention agent, can effectively improve the workability and durability of mortar. It reduces water evaporation by forming a hydrated film, improves the water retention of mortar, and slows down the hydration reaction rate of cement, thereby improving the operability of cement mortar and ensuring that the mortar maintains suitable workability for a long time. Especially in high temperature or dry environment, cement mortar is prone to water loss. The addition of cellulose ether can significantly delay water loss, reduce cracking, and ensure construction quality.
2. Application of dry mortar
Dry mortar (including putty powder, tile adhesive, plaster mortar, etc.) is a widely used material in modern construction, and the application of cellulose ether is crucial. Cellulose ether can improve the fluidity, water retention and adhesion of dry mortar, making it easier to construct. It can improve the operability of dry mortar, reduce stratification, and improve the adhesion and strength of mortar, thereby improving construction efficiency and use effect. In addition, cellulose ether can prevent dry mortar from agglomerating during storage and transportation.
3. Performance improvement of wall coatings
Architectural coatings are essential materials in building decoration. Cellulose ether, as a thickener, can improve the rheological properties of coatings, making it easier to evenly apply the coating during construction and reducing dripping. It also has good water retention, which helps to improve the water resistance, durability and construction performance of the coating. The addition of cellulose ether can enhance the thickness and adhesion of the coating, especially in some high-quality exterior wall coatings, it can significantly improve the stability and smoothness of the coating and avoid cracking and shedding of the coating.
4. Enhance the adhesion of building materials
Construction-grade cellulose ethers play a role in enhancing the adhesion of some special building materials, especially in tile adhesives, gypsum powder, adhesives, etc. Cellulose ethers can not only improve the initial adhesion of these materials, but also extend their open time to ensure that there is enough time for adjustment during the construction process. At the same time, cellulose ethers can also improve the slippage of these materials, making the construction process smoother and improving the construction efficiency and quality of the materials.
5. Application in precast concrete
Cellulose ethers also play a vital role in the production of precast concrete products. It can increase the workability of concrete, making it easier to pour and shape. Cellulose ethers can improve the fluidity, adhesion and water retention of concrete, and avoid problems such as bleeding and segregation during the pouring process of concrete. In addition, cellulose ethers can enhance the surface smoothness and crack resistance of concrete, and improve the strength and durability of precast concrete.
6. Performance improvement of gypsum-based building materials
Gypsum, as a commonly used building material, is widely used in plastering and ceiling projects. As a thickener and water-retaining agent, construction-grade cellulose ether can significantly improve the workability and construction properties of gypsum. It can increase the water-retaining capacity of gypsum and prevent the gypsum from hardening prematurely due to too fast evaporation of water during the construction process. Cellulose ether can also improve the crack resistance of gypsum, making gypsum-based building materials more stable and durable, reducing cracking and ensuring the construction effect.
7. Application in waterproof materials
Cellulose ether can also be used in building waterproof materials to enhance their adhesion and construction properties. Waterproof materials generally have a high viscosity. The addition of cellulose ether can improve their construction properties, make the application more uniform, and avoid the shedding and cracking of the coating. In addition, cellulose ether can also improve the adhesion of waterproof materials, enhance the adhesion between the waterproof layer and the base layer, prevent water penetration, and improve the waterproof effect of the building.
Construction-grade cellulose ether is widely used in the construction industry, and its unique physical and chemical properties make it an indispensable additive in building materials. It can not only improve the construction performance of building materials, enhance the adhesion, water retention and stability of materials, but also improve the durability and quality of building products. With the increasing demand for high-performance building materials in the construction industry, the application prospects of construction-grade cellulose ether will be broader in the future.
