Ruinuo Ductile Thin Spray Material (TSL-1)——Green and high-efficiency spray-on protective material for coal and rock mass surfaces
Product Introduction
This product is a two-component system consisting of a water-based resin solution (Component A) and an inorganic powder material (Component B).
Component A: Composed of an emulsion (~55% water content) and thickeners.
Component B: Contains ultrafine cement, nano silica fume, PP fibers, and other powdered materials.
Application:Mixed at a 1:1 weight ratio and applied using specialized pneumatic spraying equipment and spray guns.
Key Features:
- No rebound during spraying, eliminating dust pollution.
- Rapid hardening with strong adhesion and high tensile strength.
- Excellent deformation resistance, flame retardancy, and anti-static properties.
- Minimal reaction heat, ensuring high application safety.
- Customizable colors (white, black, sky blue) for underground roadway requirements.
National Invention Patent (Patent No.: ZL201510002249.0).
Product Features
-
Inorganic material reaction with negligible heat generation, ensuring secure application.
-
High bond/shear strength, excellent deformation resistance, providing rapid surface support and permanent sealing.
-
Rapid Curing,Non-sagging application on vertical surfaces and ceilings.
-
Flame-retardant and anti-static properties.
-
Quick, simple construction with no rebound and minimal environmental impact.
Application Scope
- Thin spray for leakage and gas leakage prevention on the surface of coal mass in mining roadway of high gas mine or inflammable and high temperature coal seam mine.
- Surface thin spray to prevent cracking and air leakage of coal mass in important underground buildings such as main roadway and machine chamber.
- Rapid surface protection and support of expansive soft rock to prevent moisture erosion.
- Rapid thin spray support protection after roadway anchor rod mesh support.
- The coal seam left roadway side of the coal mine is adapted to the large deformation and sealing of harmful gases in the mined-out area.
