LBTZ-223 Waterproof Coating Self-Sealing Tester (New Standard)

The polymer‑cement waterproof coating self‑healing tester is used to evaluate the ability of a coating film to self‑heal and seal cracks under aqueous conditions, driven by physical and chemical reactions. Under specified test conditions, cracks are induced in the polymer‑cement waterproof coating using a prescribed method, and the specimen is subjected to a defined water pressure at the crack location. The test reports the duration from the onset of water penetration at the crack to the cessation of leakage.

LBTZ-223 Waterproof Coating Self-Sealing Tester (New Standard)

Description

Product Introduction:

The polymer‑cement waterproof coating self‑healing tester is used to evaluate the ability of a coated film to spontaneously heal and seal cracks under aqueous conditions, driven by physical and chemical reactions. Under specified test conditions, the polymer‑cement waterproof coating is intentionally cracked using a prescribed method, and the crack is subjected to a defined water pressure. The test reports the duration from the onset of water penetration at the crack to the cessation of leakage. The instrument incorporates a high‑precision liquid‑level sensor and an intelligent droplet‑counting system, enabling real‑time monitoring of liquid‑level changes and the number of leaking droplets during the test, as well as automatic calculation of the non‑leakage period. This provides reliable data for assessing the self‑healing performance of waterproof coatings. The device complies with the standard requirements of GB/T 23445‑2025 “Polymer‑Cement Waterproof Coatings.”

Product Features:

1. Standard Compliance

The entire system is designed in strict compliance with the new national standard GB/T 23445-2025, and its test procedures, control parameters, and result‑evaluation criteria fully meet the regulatory requirements, ensuring that the test data are legally valid.

2. High-precision automatic detection

Equipped with a highly sensitive liquid-level sensor, it delivers measurement accuracy of up to ±1 mm and provides real-time, dynamic display of the liquid level. Featuring an intelligent droplet‑recognition and detection module, it automatically collects and tallies the total number of droplets over a 2‑minute period, eliminating human‑counting errors and ensuring precise, objective results.

3. Smart touch control + data retention

It features a touch‑based human–machine interface that integrates multiple functions, including test initiation, parameter configuration, data retrieval, and curve analysis. The equipment automatically records the entire test process—covering start and end times, dynamic changes in liquid level, droplet count, and more—thereby generating a comprehensive test archive. It also supports one‑click export of test data, process logs, and historical operating curves to a USB flash drive, facilitating data traceability, analytical organization, and rapid generation of test reports.

4. Corrosion-resistant, durable, and easy to maintain

The test tank is constructed from stainless steel, offering excellent corrosion resistance and aging durability. Its smooth surface is easy to clean, ensuring long-term performance without rusting and facilitating convenient equipment maintenance.
