On November 14, 2025, Changsha Tongqiang Electronic Technology Co., Ltd. ("Tongqiang") welcomed a delegation from the Hunan Sichuan-Chongqing Chamber of Commerce, led by its President Wang Liming. The visiting group also comprised Council Members Wu Zaohong and Tao Jianbo, Standing Deputy Secretary-General Dai Hong, along with members Zhu Xiaoli, Yang Zixuan, Liu Bin, Bai Gaohui, and Secretariat staff member Feng Ling.

General Manager Xie Xiangzhi presented a comprehensive overview to the visiting delegation, showcasing Tongqiang's pioneering technologies and extensive practical experience in anti-seepage and dehumidification for underground engineering.

As a technology enterprise integrating R&D, production, sales, export, and service, Tongqiang is steadfastly committed to technological innovation and quality enhancement. The company's accomplishments include 33 national invention patents, recognition as a National High-Tech Enterprise, EU CE certification, and designation as a Hunan Provincial Sci-Tech SME.

Furthermore, Tongqiang contributed its expertise in electro-osmotic pulse technology to the development of national building industry standards, specifically the "Technical Specification for Strengthening Underground Space of Existing Buildings" and the "Technical Specification for Water Leakage Treatment in Underground Engineering," thereby lending its intellectual prowess to advance industry standards.

During the exchange, General Manager Xie Xiangzhi spotlighted the company's core product: the self-developed "TQ-EPT Electro-osmotic Pulse Anti-seepage and Dehumidification System."

This system seamlessly integrates cloud and IoT technologies, enabling intelligent, data-driven operations with robust capabilities for remote monitoring, control, and maintenance. It is designed to thoroughly resolve seepage and humidity challenges in various underground spaces at their root cause.

Detailed case studies were presented to the delegation, demonstrating the technology's successful application and remarkable results across numerous sectors. These included road subgrades, civil air defense projects, defense storage facilities, subway tunnels, cultural heritage preservation, and civil buildings.

This visit by the Chamber of Commerce served not only as a valuable opportunity for Tongqiang to present a comprehensive report and engage in in-depth dialogues with our partners, but also as a practical demonstration of catalyzing the integration of industry, academia, research, and application. We gained a profound appreciation for the Chamber platform's pivotal role in fostering technological exchange and industrial collaboration among its members. Tongqiang looks forward to deepening cooperation with more outstanding enterprises within the Chamber in the future, sharing resources, and joining hands to put our shared goals into practice.

How to stop dampness and mildew

Traditional measures are overhead layer and partition wall construction, multi-layer internal and external waterproof, decorative materials as far as possible with stone, glass, tile, integrated board and other materials not afraid of water, these measures from so many years of experience are not ideal and thorough. Preventing structural moisture priority to ensure that the structure is rigid and self-waterproof, the concrete impermeability grade is enough, the construction vibration is sufficient, the demolition time is good, the maintenance is good, etc., can ensure that the structure does not appear open water leakage, other building materials masonry structure needs full mortar, surface painting quality assurance, these are the basis, On this basis, the installation of an electroosmotic pulse (electroosmotic) impermeable dehumidification system can ensure that the structure is dry. To ensure that the air is dry, you need to install air dehumidification equipment. The common market is mobile dehumidifier, central dehumidification system and air conditioning dehumidification, etc. Here, you need to match the dehumidification amount of equipment with the space. If the interior structure surface decoration material is a breathable material, it is more conducive to the electroosmotic system to play the function of reducing air humidity. If the construction of the basement is decorated in the humid and hot season, the moldy materials are best treated first, and 1-2 sets of high-power industrial mobile dehumidifier are equipped during the basement decoration to reduce the air humidity and prevent mold while decorating

We focus on accurate long-term design:

No longer the pursuit of the "big" venue of cool extravagance, people-oriented re-start, more attentively in order to make you more relaxed.

Build a self-drying system for the main structure of the house to create a more comfortable and livable indoor and underground space.

There is no doubt that a technology has been invented is great, but it is still too weak to compete for this point of enthusiasm.

Relying on the fear of noise gradually, pushed to the thorn land, is the controversy is not big enough.

When the spotlight is focused, it begins to increase the chance of "being accepted".

The iteration of technology is the wisdom of scientists,

But for the story line to be more coherent, it needs a public awareness awakening.
