Polyanionic cellulose (PAC) is a water-soluble cellulose ether derivative prepared by chemically modifying natural cellulose.It is an important water-soluble cellulose ether, which is commonly used in oil drilling, especially salt wells and offshore oil drilling.Basic information Polyanionic cellulose has good thermal stability, salt resistance, and strong antibacterial properties.The drilling fluid prepared by this product has good water reduction, corrosion inhibition and high temperature resistance properties, and is widely used in oil drilling, especially salt wells and offshore oil drilling.The main purpose of polyanionic cellulose has a wide range of applications and can be used in all industries. Among them, carboxymethyl cellulose (CMC) can provide more stable application performance.

For example: 1.It can be used as a light yarn glazing agent to replace the application of starch in the textile industry.Adding pulp to the papermaking process can improve the longitudinal strength and smoothness of the paper, improve the oil resistance and ink absorption rate of the paper.It is used in the production of soap and synthetic detergents in daily chemicals; it is used as a latex stabilizer in the rubber industry; it can be used as a filter reducer and viscosity enhancer in the drilling industry.In addition, it can be used as a thickener, emulsion stabilizer, crystallization formation inhibitor, thickener, binder, suspension, water retention agent, dispersant, etc. in fine chemical processing such as coatings, food, cosmetics, ceramic powders, leather, etc.Physical properties White to yellow powder or granules, non-toxic, odorless, hygroscopic, soluble in cold and hot water.

Chemical properties

1.Highly replaceable: the substitution value is 0.85-1.4".

Thermal stability: The performance of the aqueous solution is stable below 80℃.When the temperature is as high as 150℃, it can still show a certain viscosity and can be maintained for about 48 hours.

Acid, alkali, and salt resistance: The PH value is stable in the range of 3≤11, and it can be used in various harsh polar environments.

2.Good solubility: it is soluble in one with other cellulose ethers, water-soluble adhesives, softeners, resins, etc.When the degree of substitution of PAC is greater than 1.2, it gradually exhibits the solubility of oil.

3.Good solubility: it can be dissolved in cold and hot water faster with simple mixing equipment; hot water dissolves faster; instant PAC can be completely dissolved in a few minutes, which greatly improves the convenience of use and production efficiency.Good stability: The aqueous PAC solution has the characteristics of good light stability, long shelf life, strong antibacterial properties, and no fermentation.

4.Very low use: Due to the high degree of substitution and high stability of PAC itself, in the same use environment, its dosage is only 30% ≤60% of carboxymethyl cellulose (CMC), which reduces the cost of use to a certain extent, and has the advantages of high performance and price ratio, saving raw material consumption, high economic and social benefits.8.The main raw material of polyanionic cellulose (PAC) is refined cotton. It has no pharmacological effects and is harmless to physiology. The production process is green and environmentally friendly.9.Polyanionic cellulose can be used in deep wells and high-temperature underground operations.
