High Concentration Liquid Calcium Chloride Solution for Drilling Fluid and Concrete Accelerator Applications

Liquid calcium chloride, typically supplied as an aqueous solution with concentrations ranging from 30% to 40%, plays a critical role in water treatment, oil drilling, and construction industries due to its ease of use, rapid reaction, and suitability for precise dosing and automated feed systems.

In water treatment, it serves as an efficient "water softener" for hardness removal and a "corrosion and scale inhibitor." Due to its high concentration of calcium ions (Ca²⁺), it can be used to remove excessive carbonate hardness (temporary hardness) from water. By adding a precisely calculated dose, it encourages calcium bicarbonate to precipitate as calcium carbonate under controlled conditions before it can scale heat exchange surfaces, a process that requires subsequent settling or filtration.

More importantly, in systems like recirculating cooling water, an appropriate level of calcium ions is fundamental for forming a protective layer of calcium carbonate scale, enabling a "controlled scale" regime for corrosion inhibition. Additionally, calcium ions can stabilize dissolved organic matter in water, reducing its corrosivity towards metals.

In oil drilling fluids, liquid calcium chloride is a key component for formulating "calcium-based drilling mud" systems. By adjusting its dosage, the density and the inhibitory chemical phase of the drilling fluid can be precisely controlled. The high concentration of calcium ions effectively inhibits the hydration, swelling, and dispersion of shale and clay minerals in the wellbore, preventing wellbore instability, narrowing, or collapse. This is crucial for drilling through complex formations, especially those rich in active clays.

In the construction industry, liquid calcium chloride is a highly effective "concrete accelerator and set-accelerator." For cold-weather concreting or situations requiring rapid formwork removal and early load-bearing capacity (e.g., precast elements, urgent road repairs), adding it to the concrete mix water significantly accelerates the hydration reaction of cement minerals (particularly C3A and C3S). This shortens the setting time and markedly increases the early-age strength (1-day and 3-day strength can improve by 30% to 100% or more). However, attention must be paid to the potential risk of steel reinforcement corrosion, requiring adherence to strict standards and dosage limits.

We possess bulk supply capabilities, including tanker trucks, to meet the large-scale, continuous demand for liquid chemicals from various industrial users.
