Overview
Product overview
P-500 Shield Tunneling Argillite Dispersant is developed for shield tunneling construction in cohesive formations such as argillite and shale. It reduces the viscosity of argillite, prevents mud cake formation on the cutterhead and improves muck fluidity.
The product supports shield tunneling, TBM construction, slurry shield circulation and urban subway or tunnel projects in weak surrounding rock conditions. It can reduce cutterhead torque, improve muck discharge efficiency, reduce mechanical wear and help prevent slurry pipeline blockage.
P-500盾构泥岩分散剂面向泥岩、页岩等黏性地层盾构施工开发，可降低泥岩黏度，防止刀盘结泥饼，并改善渣土流动性。
该产品可服务盾构施工、TBM施工、泥水盾构循环系统及城市地铁或隧道工程中的软弱围岩工况。产品有助于降低刀盘扭矩，提高排渣效率，减少机械磨损，并帮助防止浆液管路堵塞。

Technical Information
Technical parameters
Typical data:
- Appearance: light yellow to brown liquid.
- Density at 20°C: 1.05±0.05 g/cm³.
- pH value: 5.0-8.0.
- Solubility: easily soluble in water.
- Direct mud cake dispersion ratio: 1:2 to 1:5, adjusted according to formation conditions.
- Concentration when used with foaming agent to prevent mud cake formation: 3%-10%.
- Applicable temperature: 3°C-80°C.
Mechanism of action:
- Penetration and stripping: surfactants penetrate into the argillite layer, destroy the layered structure and reduce cohesion.
- Dispersion and suspension: clay particles are dispersed through charge interaction to prevent agglomeration and caking.
- Lubricating film formation: a lubricating layer is formed between the cutterhead and rock cuttings to reduce friction.
技术参数
典型参数：
- 外观：浅黄色至棕色液体。
- 20°C 密度：1.05±0.05 g/cm³。
- pH值：5.0-8.0。
- 溶解性：易溶于水。
- 直接泥饼分散比例：1:2至1:5，可按地层条件调整。
- 与泡沫剂配合防止泥饼形成时浓度：3%-10%。
- 适用温度：3°C-80°C。
作用机制：
- 渗透剥离：表面活性剂渗入泥岩层，破坏层状结构并降低黏聚力。
- 分散悬浮：通过电荷作用分散黏土颗粒，防止团聚和结块。
- 润滑成膜：在刀盘与岩屑界面形成润滑层，降低摩擦阻力。
