Product Characteristics
- Water Retention: It can significantly improve the water - retention capacity of base materials such as cement and gypsum, prevent premature evaporation of water, ensure sufficient hydration of cement, and improve the strength and durability of materials.
- Thickening: As a rheological modifier, it can increase the viscosity of materials, making the material have good uniformity and stability, and preventing delamination and precipitation.
- Workability: It makes mortars, putties, etc. have good workability, smooth spreading, easy operation, reducing labor intensity and improving construction efficiency.
- Adhesion: It enhances the adhesion of materials to various substrates and improves the bonding strength. It is widely used in tile adhesives, cement plasters, etc.
- Anti - Sagging: It gives materials anti - sagging properties. In vertical construction, such as tile adhesives and exterior wall plasters, it prevents the slurry from sliding down and ensures the construction quality.
- Chemical Stability: It is stable in an alkaline environment, suitable for cement - based materials, and has certain temperature resistance and chemical corrosion resistance.
Application Areas
- Construction Industry: Widely used in tile adhesives, wall putties, plastering mortars, self - leveling mortars, exterior wall insulation systems, etc. It can improve the working performance and bonding performance of materials.
- Petroleum Industry: As a drilling fluid additive, it is used to control the viscosity and water loss of drilling fluid, improve drilling efficiency and wellbore stability.
- Daily Chemical Industry: In shampoos, lotions, cosmetics, etc., it is used as a thickener, emulsifier and stabilizer, which can improve the texture and stability of products.
- Coating Industry: As a thickener, rheological modifier and binder for coatings, it can improve the viscosity, leveling and hiding power of coatings, and prevent coating sagging and splashing.
- Textile Industry: Used as a thickener and binder for textile sizing agents, it can improve the sizing rate and wear resistance of fabrics, and improve the hand feeling and luster of fabrics.
Packaging and Storage
- Packaging: Generally, it is packed in 25 - kg bags. The inner bag is a polyethylene film bag, and the outer bag is a polypropylene woven bag or a multi - layer paper bag.
- Storage: Should be stored in a cool, dry and well - ventilated warehouse, away from fire sources and water sources, and avoid direct sunlight. The shelf life is generally 2 - 3 years.
