Calcium Chloride 77% Powder

Product definition and core attributes

Calcium Chloride 77% Powder is a high-purity dihydrate calcium chloride product developed by Golden Chemical based on local salt chemical resources. Its molecular formula is CaCl₂·2H₂O, presenting as a uniform white fine powder. It has strong hygroscopicity and easy solubility (the dissolution process is accompanied by heat release). The aqueous solution is neutral to slightly alkaline, with a freezing point as low as -15℃. It is suitable for industrial scenarios where purity and stability are strictly required.

Its core technical specifications strictly follow the 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 (calculated 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%.

As a local Factory that has been deeply engaged in the Marine Chemical industry for 20 years, Golden Chemical has always centered on compliance and stability, providing global customers with high-quality and cost-effective calcium chloride products.
