Builders Lime Powder

We are a calcium products manufacturer with over 3 years of practical experience. Many customers in environmental engineering ask us: with so many alkaline agents available, why choose our builders lime powder?

Our answer is simple: it reduces operating cost significantly.

The comparison below shows the core cost advantage of our 90% hydrated lime.

Our builders lime powder is based on a stable ≥90% Ca(OH)₂ formulation. The following data reflects consistent batch testing and production control.

●Calcium Hydroxide (Ca(OH)₂): ≥ 90%, equivalent to CaO ≥ 68%, ensuring sufficient active alkalinity and lower consumption per unit of treatment.

●Fineness options: 200 mesh, 250 mesh, 325 mesh

          ○For 325 mesh, 45 μm pass rate ≥ 95%, with reaction efficiency improved by over 30%

●Low impurities: Hydrochloric acid insoluble ≤ 1.0% – 1.5%, MgO < 2%

          ○Reduces scaling and sludge accumulation in equipment

●Specific surface area: ≥ 18–20 m²/g

          ○Enhances SO₂ absorption efficiency in flue gas desulfurization applications

An industrial wastewater treatment plant in Eastern China previously used 30% liquid caustic soda for pH adjustment and heavy metal removal. Their monthly chemical cost was nearly 200,000 RMB.

 

After switching to our CH-90-200 builders lime powder (200 mesh), the treatment cost dropped to approximately 90,000 RMB per month.

 

In addition, sludge volume in sedimentation tanks decreased, making dewatering easier and reducing overall operational burden.

 

This case has been widely shared among environmental engineering customers and is supported by real operational data and feedback.

We support OEM and ODM customization. The following product line covers most industrial applications:

We have an R&D team of 9 engineers focused on optimizing the hydration process and stability of hydrated lime products. We strictly control moisture content and specific surface area to ensure consistent activity across all batches.

 

We also provide a clear quality guarantee. All builders lime powder products come with a 3-month quality warranty after delivery. If Ca(OH)₂ content or key specifications do not meet the agreed standard, we will replace the product unconditionally.

 

We support sample testing before purchase and provide free samples up to 5 kg for on-site evaluation. Full-scale ordering can proceed after performance confirmation.

●Delivery time: 3–5 working days after deposit confirmation

●Trade terms: EXW, FOB, and DDP available

●After-sales response: within 1 hour for any technical or quality issue

●Inspection: SGS, BV, or other third-party inspections fully supported

Storage instructions:
Store in a cool, dry, and ventilated environment. Keep packaging elevated from the ground to prevent moisture absorption. After opening, it is recommended to use within 3–6 months.

For 325 mesh fine powder, usage within 3 months is recommended.

Safety notice:
This product is alkaline. Please wear protective gloves, dust mask, and safety goggles during handling.

Choosing our builders lime powder means more than purchasing a chemical material. It means adopting a cost-reduction solution supported by real industrial data, proven case results, and stable supply chain control.

It is especially suitable for wastewater treatment, environmental engineering, and flue gas desulfurization applications where cost efficiency and stability are critical.
