Capillary Drainage Pipes
Capillary drainage pipes are a type of drainage device that realizes liquid drainage by utilizing the capillary phenomenon. Its core principle is to enable water to flow spontaneously without external driving forces (such as gravity or pressure) through the micropores or gap structures inside the material, relying on liquid surface tension and adhesion, thereby achieving drainage,water conduction, or moisture retention functions.

Core Structure: Usually made of hydrophilic porous materials, such as polymer composites, modified plastics, fiber fabrics,etc., with dense capillary channels (pore size mostly in the micrometer level) formed inside to ensure that liquid can move directionally along the channels.
No external power is required; it drains independently by virtue of capillary action, which is energy-saving and has a wide, range of applications;
* Drainage efficiency is affected by material porosity, liquid properties (such as viscosity, surface tension), and ambient
temperature;
* It has a certain anti-clogging ability, and some products can reduce impurity deposition through special structural design.
