Xanthan gum, also known as xanthan gum and xanthan gum, is an off-white or light beige powder. It is a biological gum with the best performance in the world that integrates thickening, suspension, emulsification and stabilization. It is a natural polysaccharide. And important biopolymers, produced by Xanthomonas campestris from cabbage black rot using carbohydrates as the main raw material through aerobic fermentation bioengineering technology. Xanthan gum can be dissolved in cold water and hot water. It has high viscosity, high acid, alkali and salt resistance, high heat resistance, stability, suspension, thixotropy, etc., and is often used as a thickener, emulsifier, and suspending agent. , stabilizer, has broad market prospects, the specific performance is:
1. Viscosity: Low-concentration solution has the characteristics of high viscosity (the viscosity of 1% aqueous solution is equivalent to 100 times that of gelatin) and is an efficient thickener.
2. Shear resistance (pseudoplasticity): Xanthan gum solution has high viscosity under static or low shear. Under high shear, the viscosity decreases, but the molecular structure remains unchanged. When the shearing effect disappears, the viscosity returns to normal.
3. Temperature resistance: Its performance remains basically unchanged within a large temperature range (-18–120℃).
4. Salt resistance: Under conditions of higher salt concentration, it still maintains its solubility without precipitation and flocculation even in saturated salt solutions, and its viscosity is almost unaffected.
5. Acid and alkali resistance: The solution viscosity remains basically unchanged within the pH range of 1-12.
6. Compatibility and synergy: It has good compatibility with acids, alkalis, salts, preservatives, natural or synthetic thickeners in the same solution system. It can have a synergistic effect with polysaccharide gums such as guar gum and locust bean gum to double the viscosity.
7. Antioxidation and enzymatic hydrolysis: The stable double helix structure of xanthan gum makes it highly antioxidant and resistant to enzymatic hydrolysis.
8. Suspension: It has good suspension effect on insoluble solids and oil droplets.
Due to the above excellent properties, xanthan gum is widely used in hundreds of products in more than 20 industries such as food, medicine, cosmetics, papermaking, textiles, ceramics, fire extinguishing agents, daily chemicals, and oil exploration.
Petroleum drilling grade xanthan gum is an efficient, high-quality, environmentally friendly petroleum drilling mud additive. It has a wide range of applications and is resistant to temperatures (≥94°C),
It has strong tolerance to acids, alkalis, and salts, which can significantly improve the permeability of mud and the ability to suspend solid matter, reduce pressure during drilling,
Stabilize the well wall and reduce damage to the oil reservoir, thereby significantly improving the efficiency of drilling, workover, and completion work. This product has temperature and salt resistance and good shear dilution and particle suspension effects. Therefore, it is an ideal mud additive for offshore drilling. It can remain stable for a long time under saturated salt water and a temperature of 85°C. Therefore, it is an ideal oil displacing agent in high-temperature and high-salt oil fields.

Main Specifications

Products of this specification comply with the Q/XSH03-2007 standard. The temperature resistance remains stable at 105°C and is suitable for medium and deep well operations.

Packaging, storage and precautions:
1) Use 25KG composite kraft paper or paper barrels lined with moisture-proof plastic bags. The shelf life is 36 months in a closed container in a cool and dry place (the best use period is 18 months).
2) Under ambient temperature, closed and dry conditions.
3) Xanthan gum is completely soluble in most water-based phase systems, but because it is extremely hydrophilic, if it is added directly to water without sufficient stirring, the outer layer will absorb water and swell into micelles, thereby blocking the moisture. Entering the inner layer will affect its function, so you must pay attention to its correct use.
