STARCH POWDER

Starch or amylum is a white, granular, organic polymeric carbohydrate produced by all green plants. In fact, starch is a chain of sugar molecules connected together. This soft, white and tasteless powder is insoluble in cold water, alcohol or other solvents. The chemical formula of starch is (C6H10O5)n. This substance is an important component of rice, corn, wheat, beans, potatoes and many other plant foods. It is found in seeds, tubers and other parts of plants and is an important component of rice, corn, wheat, beans, potatoes and many other plant foods. In fact, it is a type of polysaccharide consisting of glucose monomers connected in α 1,4 bonds. The simplest form of starch is the linear polymer of amylose and its branched form is amylopectin.

CHARACTERISTICS 

  • Physical: Granular, biodegradable, insoluble in cold water, forms gels when heated, variable viscosity.
  • Chemical: Composed of amylose and amylopectin, undergoes gelatinization and retrogradation.
  • Functional: Acts as a thickener, binder, and film-former.
  • Nutritional: Primary energy source, includes digestible and resistant starch types.

These versatile properties make starch widely used in food, pharmaceuticals, and industrial applications.

APPLICATIONS 

  1. Food: Thickener, stabilizer, and binder in processed foods.
  2. Pharma: Filler, binder, and disintegrant in tablets.
  3. Industry: Adhesive, bioplastics, and ethanol production.
  4. Cosmetics: Absorbent and texture enhancer.
  5. Construction: Additive in concrete and gypsum.

BENTONITE

Bentonite utilizes montmorillonite as its primary mineral component, making it a key non-metallic refractory raw material. The choice of montmorillonite is based on its status as the predominant mineral in non-metallic refractory materials, commonly recognized as a source for extracting rocks. With montmorillonite constituting 85-90% of its mineral composition, bentonite’s characteristics are largely influenced by this component. The mineral can exhibit various colors, including yellow, green, gray, and white. Bentonite can manifest as dense patches and is suitable for use in loose soil, providing a distinct slippery sensation when manually ground. Moreover, its water-absorption properties are noteworthy, with a significant volume increase of 20-30 times when exposed to water, forming a suspension in abundant water and a paste in minimal water.

CHARACTERISTICS 

  • Absorbent: High water retention and swelling ability.
  • Viscosity: Excellent thickening and gel-forming properties.
  • Binding: Strong adhesive qualities in industrial applications.
  • Purity: High cation exchange capacity for ion absorption.
  • Versatile: Functions as a sealant, stabilizer, and purifier.

APPLICATIONS 

  1. Drilling Fluids: Enhances viscosity and stabilizes boreholes.
  2. Foundry: Acts as a binder in metal casting molds.
  3. Construction: Seals and stabilizes trenches and tunnels.
  4. Agriculture: Improves soil quality and water retention.
  5. Personal Care: Used in cosmetics for its absorbent properties.
  6. Environmental: Water purification and containment of contaminants.

CALCIUM CARBONATE

Calcium carbonate is a chemical compound with the formula CaCO3. It is commonly found as minerals in some rocks of the Earth’s crust, such as calcite and aragonite (especially limestone, which is a type of sedimentary rock composed mainly of calcite). Calcium carbonate is a major component in sea pearls and the shells of sea creatures, snails and eggs of egg-laying animals. Calcium carbonate is a constituent of agricultural lime and is formed when calcium ions in hard water react with carbonate ions. This substance is used to prepare stomach medicines. It is used as a raw material for the production of calcium supplements or antacid drugs, but consuming too much of it can be dangerous and cause improper digestion.

CHARACTERISTICS 

  • Chemical Formula: CaCO₃.
  • Appearance: White, fine powder or crystalline solid.
  • Solubility: Slightly soluble in water, dissolves in acids.
  • pH: Neutralizes acidity, maintaining pH balance.
  • Thermal Stability: Decomposes into calcium oxide (CaO) and CO₂ at high temperatures.
  • Abrasive Properties: Gentle abrasiveness suitable for cleaning and polishing.
  • Biocompatibility: Safe for use in food, medicine, and personal care.

APPLICATIONS 

  1. Construction: Used in cement, concrete, and as a building material.
  2. Industrial: Filler in paints, plastics, paper, and rubber.
  3. Agriculture: Soil pH regulator and nutrient source.
  4. Food Industry: Additive in baking powder, antacids, and dietary supplements.
  5. Environmental: Neutralizes acidic water and controls emissions.
  6. Personal Care: Found in toothpaste and cosmetics.
  7. Pharmaceuticals: Filler in tablets and antacid formulations.

POLYANIONIC CELLULOSE (PAC)

Polyanionic Cellulose (PAC) is a versatile, water-soluble polymer extensively used in drilling fluids to control filtration and enhance rheological properties. It is available in two grades: PAC-LV (Low Viscosity), which primarily controls fluid loss without significantly affecting the viscosity, making it ideal for low-solids and non-dispersed systems, and PAC-HV (High Viscosity), which provides both fluid loss control and increased viscosity for improved suspension and carrying capacity of drill cuttings. Both grades are compatible with a wide range of water-based systems, including freshwater, seawater, and brines, and are essential for ensuring drilling fluid stability and efficiency.

CHARACTERISTICS 

  • Viscosity Control: Available in low viscosity (PAC-LV) and high viscosity (PAC-HV) forms to adjust the rheological properties of drilling fluids.
  • Fluid Loss Control: Effectively reduces fluid loss, preventing excessive seepage into formations during drilling.
  • Salt Tolerance: Resists contamination from salts and chemicals, making it ideal for saline or complex environments.
  • Suspension Properties: Enhances the suspension of drill cuttings, boosting drilling efficiency.
  • Environmental Friendliness: Biodegradable, offering an eco-friendly alternative to other polymers.
  • Stability: Maintains stability under varying temperature and pressure conditions for consistent performance.

 

APPLICATIONS 
  1. Oil and Gas Drilling: PAC is widely used in water-based drilling fluids to improve viscosity, control fluid loss, and enhance the suspension of drill cuttings. This improves overall drilling efficiency and wellbore stability.
  2. Hydraulic Fracturing: PAC is used in fracking fluids to maintain the required viscosity and suspension properties, ensuring effective fracture propagation and proppant transport.
  3. Mining: PAC is applied in mining operations for ore processing, where it helps to control fluid loss and maintain consistent fluid properties under various conditions.
  4. Construction: PAC is used in cement and concrete applications to modify the rheological properties and reduce water usage while improving fluidity and workability.
  5. Agriculture: PAC can be employed in agriculture as a stabilizer in irrigation systems and to improve soil retention in areas with high water permeability.
  6. Cosmetics and Pharmaceuticals: PAC is used in personal care products and pharmaceuticals as a binder or thickener to improve the consistency and performance of formulations.
