1. What is the HDS series high-efficiency water-reducing agent?
HDS系列是一种专为耐火浇注料和胶凝材料设计的高性能Polycarboxylate-based superplasticizer. It can significantly reduce water consumption in high-temperature environments while improving fluidity, density, and coagulation performance.
2. What advantages does HDS have over refractory castables?
Low water consumption（Reduce porosity, enhance thermal shock resistance）
Excellent performance(Ensure that fine powders such as alumina and silica are evenly distributed)
Higher intensity（Optimize particle gradation, improve normal/high temperature mechanical strength）
Controllable condensation time（Adjustable to accommodate large or precise construction）
3. Is HDS compatible with common refractory materials?
Fully compatible, including:
4. What is the recommended dosage of refractory materials?
Standard Range：0.1%-0.5% of the dry material weight (specific adjustments should be made based on the material composition and flowability requirements)
Excessive Risk: May cause excessive retardation or segregation
5. Will HDS affect the high-temperature performance of the material?
No. HDS will completely decompose during the sintering process (usually above 300°C), leaving no ash or by-products that damage the refractory structure.
6. How should HDS be stored?
Powder：Sealed moisture-proof packaging (≤25°C, relative humidity <60%)
Liquid剂：Avoid freezing and direct sunlight, shelf life 6-12 months
7. Can HDS replace traditional lignosulfonate-based water reducers?
Yes, and has:
Higher water reduction rate（up to 30%, while lignin is only 10-15%）
Less intake（Crucial for dense refractory materials）
8. Does HDS meet environmental requirements?
符合REACH/ROHSStandard. Non-toxic, but must be used in accordance with chemical standards operating specifications.
