Deepen Technological Innovation, Consolidate the Foundation of Quality — Meibu Obtains Invention Patent for Slow Expansion Force Acquisition and Testing

Release Time：

2026-02-10

Recently, Hangzhou Meibu Materials Technology Co., Ltd. has achieved important results in the field of material testing and performance evaluation, having been granted the invention patent titled Slow Expansion Force Acquisition and Testing Method and Device (patent details can be supplemented as actual conditions require). This patent innovatively delivers an integrated overall solution for slow expansion force testing, which can accurately meet the pressure performance testing requirements of slow-expansion materials such as polyurethane grouting materials under diverse media and temperature environments. It provides high-precision and highly reliable core data support for the R&D optimization and practical application of engineering materials, filling a niche technical gap in relevant testing sectors.

Boasting both innovativeness and practicability in technical design, the invention patent features four core highlights as follows:
Special amorphous thin-walled metal tanks are adopted to minimize the interference of the tank itself on test results from the source, ensuring test data truthfully reflect the inherent expansion pressure characteristics of materials.
An innovative combination of dual check valves and liquid pressure difference evacuation method is deployed to completely remove air inside the test tank, eliminating adverse impacts of residual air on data accuracy throughout the testing process and further improving measurement precision.
High-precision electronic pressure gauges and an intelligent constant-temperature system are integrated to realize fully automatic control of the testing process and continuous data monitoring, lowering manual operation errors and boosting testing efficiency and stability.
The system can automatically plot variation curves of expansion force and accurately calculate peak pressure values, offering intuitive and quantitative reference standards for material performance analysis and facilitating scientific decision-making for R&D and engineering application.
The successful implementation and authorization of this patented technology marks a solid and crucial leap forward for Hangzhou Meibu Materials Technology Co., Ltd. in the R&D of material testing equipment and process innovation, demonstrating the company’s independent R&D strength and capability for innovative breakthroughs in core technologies. Distinguished by uniform stress bearing, accurate data, continuous testing, easy operation and wide versatility, this technology boasts extensive application scenarios. It can not only satisfy performance evaluation demands for new slow-expansion materials in laboratory stages and strongly support material R&D optimization, but also be extended to practical engineering fields including engineering quality control, material matching selection and service life prediction. It holds extremely high promotion value and application potential in key scenarios such as geotechnical engineering, waterproofing and leakage stoppage, and foundation reinforcement, and can effectively tackle industry pain points including insufficient testing precision and cumbersome operation in related sectors.
Moving forward, Hangzhou Meibu Materials Technology Co., Ltd. will stay focused on technological innovation of materials and deepen the layout of independent intellectual property rights while continuously strengthening core technology R&D capabilities. Relying on this newly authorized patented technology and subsequent innovative achievements, the company will deliver more accurate, efficient and targeted testing solutions for industry clients. Driven by technological innovation, it will advance industrial transformation and upgrading, and facilitate the steady progress of engineering practices toward scientization, refinement and high quality.
