77% Calcium Chloride Powder is a high-purity calcium chloride dihydrate product developed by our factory using local salt chemical resources. Its molecular formula is CaCl₂·2H₂O, and it appears as a uniform white fine powder. It is highly hygroscopic and readily soluble (the dissolution process is exothermic). The aqueous solution is neutral to weakly alkaline, with a freezing point as low as -15℃. It is suitable for industrial applications with strict requirements for purity and stability.

Its core technical indicators strictly comply with GB/T26520-2011 standard:

Calcium Chloride (CaCl₂) Content: 77%±1% (batch fluctuation ≤0.8%)

Sodium Chloride (NaCl) Impurities: ≤2.8% (industry average ≤3.5%)

Water Insoluble Matter: ≤0.1% Sulfate (as CaSO₄): ≤0.05%

Hardness: >75 Newtons; pH Value: 8-10

Differentiated competitive advantage

1. Leading purity stability: Through the “multi-stage brine refining + closed-loop drying” process, the content fluctuation between batches is less than 1% (while the competing products are generally 2%-3%), avoiding the need for downstream production to adjust process parameters due to fluctuations in raw material purity, and increasing production efficiency by approximately 12%.
2. Stricter impurity control: The impurity content of sodium chloride is 0.7 percentage points lower than the industry standard, and the sulfate content is only 50% of the standard value. When used as a water treatment agent, it can reduce the risk of equipment scaling and lower the maintenance costs for customers.
3. Broader compliance coverage: In addition to obtaining the ISO9001-2008 quality management system certification, the EU REACH regulation registration has been completed, and the products can directly enter the EU market. For export orders, SGS third-party test reports can be provided, covering 18 indicators such as purity, impurities, and heavy metals.

Application Scenarios

Typical applications of Calcium Chloride 77% Powder include:

-Municipal road Snow melting: In an environment of -10℃, a spreading amount of 20g/㎡ can completely melt the ice layer within 2 hours, and the corrosion rate of asphalt pavement is less than 0.02mm/ year (lower than the industry average of 0.05mm/ year).

Industrial raw material drying: As a container desiccant, it has a moisture absorption rate of 130% of its own weight within 24 hours, which can reduce the moisture damage rate of high-value goods (such as electronic components and precision instruments) to below 0.1%.

Rapid setting of Building materials: When added to plastering mortar, it can shorten the setting time by 3 to 4 hours and increase the compressive strength of the mortar by approximately 8%.
