Fumed Silica
Fumed silica is with small particle size, large surface area and porous structure, those properties ensures good adsorption ability and great hygroscopicity. In food powder, fumed silica covers all around the powder, it can separate particles, so to decrease viscosity and to ensure excellent flowing property. And, numerous internal pores of fumed silica can adsorb the humidity around food product, it avoids agglomeration when stored.

In the water supply pipe network system, the major causes of water leakage in the pipe network are climate change factors and insufficient depth of pipe. Changes in temperature and humidity during the climate change will affect the pipeline network, and then being squeezed by heavy objects will cause the foundation of the pipeline network system to sink, causing the pipeline to rust, crack and leak. In addition, there may be some cases of theft of water caused by the incomplete management system, and the construction of deep excavation of the foundation of the construction project, which results in the occurrence of pipeline gaps. Therefore, how to effectively implement leakage control is the key to effective and active leak detection of the water supply network and timely detection and repair of water leakage. In this regard, there have been many professional departments and water meter companies have developed corresponding leakage monitoring equipment.
The most important principle is that active leak detection is also called listening. Listening method is a method of using sound wave technology, using listening equipment (such as a leak detector, leak detector, etc.) to find leakage sound and determine the leaking point. It is the most commonly used and more effective in leak detection work. A method of leaking. This principle is the product of a series of ultrasonic flow measurement products independently researched and developed by renowned water meter companies Huizhong. China Huizhong has long been dedicated to the research, development, manufacture, promotion and service of serial software and products in the field of ultrasonic flow measurement, and has been unremitting for more than 20 years. Efforts have been made to gradually increase the coverage of these products from industry to civilian use, from flow to heat, and from China to the world's various production and living areas.
In the just-concluded academic exchange, representatives of Harbin Water Supply Group Co., Ltd. who were invited to attend the meeting gave high praise to this series of products. He also expressed his opinions on the application of zonal metrology in urban water supply networks. Water supply pipe network zoning measurement appeared in the 1980s. The British Water Association first proposed this concept. Through continuous monitoring of the inflow and outflow of water in an independent area, the analysis of leakage in the region and the positioning and repair through leakage To achieve the purpose of reducing leakage. It has now become an important topic of discussion in the construction of urban pipe networks.
Sharon was sponsored by the School of Municipal and Environmental Engineering of Harbin Institute of Technology and co-organized by Huizhong Instrument Co., Ltd., and Nan Jun, the deputy dean of HIT’s Municipal Environmental Engineering Institute, attended and delivered opening remarks. Industry leading experts Professor Liu Zhaoqing of Tongji University and Prof. Zhao Hongbin of Harbin Institute of Technology also shared the theme report. The company has conducted professional and in-depth exchanges on issues such as the water supply network, zoning and measurement, and smart water services. The on-site interaction is frequent and the atmosphere is warm.
Huizhong Helps Water Supply Network Divisional Measurement Academic Salon Successfully Held
[China Instrument Network Instrument Enterprise] The urbanization construction continues to advance, the old pipe network in the urban area has been greatly transformed, the quality of the drainage pipe project has been continuously improved, and people's focus on the management of water resources has gradually shifted from “open source†to “throttling†and leakage. The problem is getting more and more attention. As an effective method to control the leakage of pipeline network, district measurement and regional management are increasingly concerned by water supply companies and water industry associations. Recently, an academic salon called "urban pipeline network research" has attracted widespread attention in the industry.
