Linear alkyl benzene sulphonic acid labsa

Linear alkyl benzene sulphonic acid labsa reference image:

Free oil: <1.8% (too high reduces the effectiveness of active substances)

Sulfate: <1.5% (reduces equipment corrosion)

Quality control key: infrared spectroscopy detection of sulfonic acid peak (1180 cm⁻¹) to ensure the absence of unsulfonated oil.

We can provide customized products to meet the needs of different industries

We can provide:

Low dioxane type: <10 ppm (for personal care)

Light color type: ≤50 Hazen (high-end detergent)

Narrow fraction type: C12 accounts for >85% (high foam demand)

Cold-resistant type: freezing point <5℃ (applicable to cold areas)

At the same time, our company can also provide compounding technical support, such as compounding with non-ionic surfactants to reduce the critical micelle concentration (CMC).

Linear alkyl benzene sulphonic acid labsa is also the core emulsifier of photovoltaic silicon wafer cutting fluid, reducing silicon powder agglomeration by 30%, and a permeability enhancer for shale gas fracturing fluid, reducing rock adsorption loss.

LABSA's technological breakthrough in the cement industry

III. Key process breakthroughs

1. Gradient hydration heat management

LABSA neutralization reaction absorbs heat (ΔH=-58kJ/mol)

→ Peak hydration heat drops from 268J/g to 193J/g

→ The risk of temperature difference cracks in large-volume concrete is reduced by 72%

2. Self-healing microchannel construction

Nano-tubular calcium sulfate forms "whisker bridges" at the cracks:

Crack width <50μm → Contact with water → Secondary growth of calcium sulfate tubes (rate 2μm/h) → 7d self-healing rate 89%

3. Heavy metal solidification enhancement

Sulfonic acid chelates Pb²⁺/Cd²⁺ to generate insoluble sulfonates

→ Heavy metal leaching concentration is lower than GB 5085.3 limit 90%
