LBT090C Fully Automatic Vertical Water Permeability Tester for Plastic Drainage Boards (Horizontal Type)

Description

Product Introduction:

Plastic drainage boards, also known as geosynthetic drainage strips or plastic sheets, are commonly used strip‑type drainage materials with a cross‑sectional width of 10 cm and a thickness of approximately 5 mm. Their key quality indicators include the tensile strength of the composite structure and the filter membrane, as well as the longitudinal water permeability. These properties are evaluated in accordance with the standards JTG 3460‑2026 “Test Procedures for Geosynthetics in Highway Engineering,” SL 235 “Test Procedures for Geosynthetics,” DL/T 5886 “Test Procedures for Geosynthetics in Water Conservancy and Hydropower Projects,” and JTS 206‑1‑2009, which specify methods for determining the longitudinal water permeability of plastic drainage boards and other drainage materials.

Key features:

1. A brand-new horizontal‑type model, featuring a specially designed rapid sample‑clamping mechanism for convenience, speed, and high efficiency.

2. It features an aircraft-grade aluminum pressure chamber and experimental cabin design, offering high compressive strength.

3. Programmable automatic control of the hydraulic gradient ensures precise and stable head regulation.

4. Pneumatic specimen clamping saves time and effort, enhancing testing efficiency.

5. The electronic temperature sensor displays the temperature with high accuracy.
