I. Technical Breakthroughs of Powder Polycarboxylate Superplasticizer

‌(‌1) Solid-state Continuation of High-efficiency Water-reducing Performance
Huaxuan High Technology's powder polycarboxylate superplasticizer series retains the comb-like molecular structure of liquid products through solution polymerization followed by spray drying technology. The dual action of carboxyl groups and ether side chains ensures a stable water reduction rate of 35%-45%. The dry powder form eliminates performance fluctuations caused by water evaporation during transportation, making it particularly suitable for remote area projects.

(‌2) Quality Improvement through Process Innovation
The mother solution is atomized and exposed to hot air (180-220°C), instantly evaporating moisture to form powder. This process precisely controls the molecular chain structure while maintaining excellent dispersibility, achieving a paste fluidity of 235 mm. The powder product contains no solvent residue, enabling more direct electrostatic repulsion with cement particles, resulting in a 50%+ increase in early strength.

‌II. Significant Advantages in Engineering Applications‌‌

(‌1) Revolutionary Construction Convenience‌‌ 

* Instant Mixing:‌ No on-site dilution required; directly blend with dry-mixed mortar to reduce mixing errors.

* Extended Shelf Life:‌ Powder form extends storage life to 12 months without being affected by low-temperature freezing.

(‌2) Comprehensive Economic Benefits

* Lower Transportation Costs:‌ 1 ton of powder equivalent to 3-5 tons of liquid product in active content, reducing logistics costs by 60%.

* Precise Dosage Control:‌ Maintains high performance at an ultra-low dosage of 0.12%-0.24%, reducing cost per cubic meter of concrete by 8-12 yuan.

(3) Win-win for Environmental Protection and Durability‌‌

* Zero Formaldehyde Emissions:‌ Production complies with ISO 14000 standards, with alkali content ≤0.2%.

* Improved Volume Stability:‌ Shrinkage rate ≤135%, significantly reducing concrete cracking risks.

‌III. Future Development Trends

Powder polycarboxylate superplasticizers demonstrate unique advantages in emerging fields such as UHPC (Ultra-High Performance Concrete), prefabricated construction, and 3D-printed concrete. With the expansion of dry-mixed mortar markets, their anhydrous application mode will become a key development direction in green building materials.
