Polyanionic cellulose (PAC) is a water-soluble cellulose ether derivative prepared by chemical modification of natural cellulose. It is an important water-soluble cellulose ether. It is usually used as its sodium salt and is widely used in oil drilling, especially salt water wells and offshore oil drilling. PAC-Application In Petroleum 1. The functions of PAC and CMC in oil field are as follows: - The mud containing PAC and CMC can make the well wall form thin and hard filter cake with low permeability and reduce the water loss; - After adding PAC and CMC into the mud, the drilling rig can obtain low initial shear force, make the mud easy to release the gas wrapped in it, and quickly discard the debris in the mud pit; - Like other suspended dispersions, drilling mud has a certain existence period, which can be stabilized and extended by adding PAC and CMC. 2. PAC and CMC have the following excellent performance in oilfield application: - High degree of substitution, good uniformity of substitution, high viscosity and low dosage, effectively improving mud service efficiency; - Good moisture resistance, salt resistance and alkali resistance, suitable for fresh water, seawater and saturated brine water-based mud; - The mud cake formed is of good quality and stable, which can effectively stabilize the soft soil structure and prevent shaft wall collapse; - It is suitable for mud systems with difficult solid content control and wide variation range. 3. Application characteristics of PAC and CMC in oil drilling: - It has high water loss control ability, especially efficient fluid loss reducer. With low dosage, it can control water loss at a high level without affecting other properties of mud; - It has good temperature resistance and excellent salt resistance. It can still have good water loss reduction ability and certain rheology under a certain salt concentration. The viscosity is almost unchanged after dissolving in salt water. It is especially suitable for offshore drilling and deep wells; - It can well control the rheology of mud and has good thixotropy. It is suitable for any water-based mud in fresh water, seawater and saturated brine; - In addition, PAC is used as cementing fluid to prevent fluid from entering pores and fractures; - The filter press fluid prepared with PAC has good resistance to 2% KCl solution (it must be added when preparing filter press fluid), good solubility, convenient use, can be prepared on site, fast gel forming speed and strong sand carrying capacity. When used in low permeability formation, its filter press effect is more excellent.

The Redispersible Polymer Powder is powder materials with Green Environmental Protection, Building Energy Saving ,high quality and Multipurpose which also is important functional additive in dry-mixed mortar. The powder can improve the mortar's performance, increase the strength of mortar and bond strength onto substrates, improve flexibility and mortar deformation, compressive strength, flexural strength, wear resistance, toughness, adhesion, water-holding capacity and constructability. In addition, it can make mortar waterproof. Redispersible polymer powder is mainly applied to internal and external putty, ceramic tile adhesive, ceramic tile Crack Sealer, dry powder interfacial agent, Exterior wall using outside insulation mortar, self flowing mortar, repair mortar, decorative plaster, waterproof mortar etc. Wall putty powder redispersible emulsion powder-Product Uses 1. It is mainly used as putty glue powder in building putty powder to process and produce interior wall high hardness and water-resistant putty powder, which has the characteristics of high hardness and water resistance. Compared with polyvinyl alcohol, the product has low cost and good quality, and has been rapidly popularized and used in the putty powder industry in China. 2. Used as adhesive, thickener and emulsifier in putty powder industry. It can be used in emulsion paint, real stone paint and stone paint to reduce the cost. Characteristics : The product can be dispersed in water, which can improve adhesive force between mortar and its supports; high impact resistance; it can also improve the constructability and mechanical properties of the mortar. Package: Compound triple paper-plastic bag. N.W. is 25 kg/per bag Shelf life: 180 days. Exceeding valid period, if the products have not lumped it can still be used.

Polyanionic cellulose (PAC) is a water-soluble cellulose ether derivative prepared by chemical modification of natural cellulose. It is an important water-soluble cellulose ether. It is usually used as its sodium salt and is widely used in oil drilling, especially salt water wells and offshore oil drilling. PAC-Application In Petroleum 1. The functions of PAC and CMC in oil field are as follows: - The mud containing PAC and CMC can make the well wall form thin and hard filter cake with low permeability and reduce the water loss; - After adding PAC and CMC into the mud, the drilling rig can obtain low initial shear force, make the mud easy to release the gas wrapped in it, and quickly discard the debris in the mud pit; - Like other suspended dispersions, drilling mud has a certain existence period, which can be stabilized and extended by adding PAC and CMC. 2. PAC and CMC have the following excellent performance in oilfield application: - High degree of substitution, good uniformity of substitution, high viscosity and low dosage, effectively improving mud service efficiency; - Good moisture resistance, salt resistance and alkali resistance, suitable for fresh water, seawater and saturated brine water-based mud; - The mud cake formed is of good quality and stable, which can effectively stabilize the soft soil structure and prevent shaft wall collapse; - It is suitable for mud systems with difficult solid content control and wide variation range. 3. Application characteristics of PAC and CMC in oil drilling: - It has high water loss control ability, especially efficient fluid loss reducer. With low dosage, it can control water loss at a high level without affecting other properties of mud; - It has good temperature resistance and excellent salt resistance. It can still have good water loss reduction ability and certain rheology under a certain salt concentration. The viscosity is almost unchanged after dissolving in salt water. It is especially suitable for offshore drilling and deep wells; - It can well control the rheology of mud and has good thixotropy. It is suitable for any water-based mud in fresh water, seawater and saturated brine; - In addition, PAC is used as cementing fluid to prevent fluid from entering pores and fractures; - The filter press fluid prepared with PAC has good resistance to 2% KCl solution (it must be added when preparing filter press fluid), good solubility, convenient use, can be prepared on site, fast gel forming speed and strong sand carrying capacity. When used in low permeability formation, its filter press effect is more excellent.
