At the highlight moment of the Sound Expo, General Manager Tian Jun County gave a keynote speech, unlocking a new era of floor and floor sound insulation! The 8th China Acoustic Industry Development Conference (CAAF Acoustic Expo) in 2026 will be attended by big names and will be an unprecedented event. Mr. Tian Junxian, general manager and senior engineer of Zhejiang Keda New Building Materials Co., Ltd., was invited to the stage to deliver an authoritative report on the theme of 'Exploration of Full-Functional Solutions for Floor Sound Insulation and Insulation Engineering'.

Editor's note: In order to promote green and low-carbon transformation and help achieve the 'double carbon' goal, the association launches a display of outstanding achievements of member units. The display covers the fields of urban renewal, eco-city and green smart manufacturing, presenting innovative practices and cutting-edge results in low-carbon development. We hope that through sharing and communication, we can gather industry wisdom, jointly promote high-quality development of the industry, and assist Zhejiang's 'double carbon' construction. Introduction to the results: SPD water-based foamed polyurea sound insulation board (hereinafter referred to as SPD board) is a new type of board with water-based polyurea foam as the core layer and two sides covered with cement mortar cloth, which can improve the sound insulation and heat preservation functions of floors and floors. 'Compatible with sound insulation and thermal insulation' High-quality sound insulation: SPD water-based polyurea foam has the smallest cells (micron level) and the highest closed cell rate among many foams, and it has an internally plasticized elastic (flexible) soft segment molecular chain structure. When the mechanical vibration energy wave of impact sound passes through the foam, 60% is 'damped' and 40% is 'sound-absorbed', showing a high

On January 27, 2026, the fourth council and commendation meeting of the fifth session of the Shaoxing Exploration and Design Industry Association concluded successfully at the Shaoxing International Hotel. This meeting mainly includes the summary of the association's work in 2025, the association's work ideas in 2026, the display of outstanding works in the 'Good House' design competition, and the commendation of the annual advanced ones. Zhejiang Keda New Building Materials Co., Ltd. was awarded the title of 'Advanced Member Unit'. At the meeting, Director Chen of the Shaoxing Municipal Housing and Urban-Rural Development Bureau made an important speech, requiring the association’s work to be integrated with the policies and spirit of central documents, encouraging the association to break through, innovate, and try, and create a fair competition environment for the industry. At the same time, Director Chen fully affirmed Zhejiang Keda New Building Materials Co., Ltd.'s exterior wall insulation, floor and floor sound insulation and waterproof series products, and highly praised Keda's spirit of continuous innovation and keeping up with the development pace of 'good houses'. Mr. Tian Junxian, general manager of Keda Company, wrote 'SPD Water-based

Supported by Zhejiang Building Waterproofing Industry Association, Zhejiang New Wall Materials Industry Association, Water Supply and Drainage Professional Committee of Hangzhou Civil Engineering and Architecture Society, Zhejiang Building Materials Industry Association, sponsored by Chief Engineer's Home (CEA), Chief Engineer's Home (Zhejiang) ) Operation Center hosted the '2026 Green Building Chief Engineer (CTO) Summit Forum/The 12th CTO Home (Zhejiang) Academic Annual Conference', which was grandly held on the afternoon of January 10, 2026 at Hangzhou Haihaihai International Hotel. With the theme of 'Technological Innovation, Craftsmanship, Green Empowerment, and Collaborative Construction', this conference brought together more than a hundred project directors, chief engineers, procurement and cost directors, technical experts and industry leaders from real estate development, architectural design, construction, material research and development, technology companies and university scientific research institutions across the country to conduct in-depth discussions around core topics such as green building policy trends, technological innovation, and engineering practice.

As the '15th Five-Year Plan' is about to begin, the low-carbon construction industry and 'good house' construction conference under the background of 2025 urban renewal was successfully held in Chuzhou, Anhui. With the theme of 'Technology Empowering a Zero-Carbon Future,' this conference brings together elites from all walks of life in government, industry, academia, and research to discuss how to promote the green transformation of the construction industry through technological innovation and industrial collaboration under the guidance of the 'dual carbon' goal, and build safe, comfortable, green, and smart 'good houses' for the people. The conference was guided by the China Building Materials Industry Economics Research Association and co-sponsored by the Low-Carbon Building Branch of the China Building Materials Industry Economics Research Association, the Construction and Engineering Disaster Prevention and Mitigation Branch of the China Disaster Prevention Association, the Zhongguancun Aosen Park Green Building Innovation Technology Alliance, the Anhui Urban Science Research Promotion Association, and the Anhui Artificial Environment and Low-Carbon Energy Society. It is organized by the Green and Low-Carbon Construction Branch of the China Building Energy Conservation Association, the Comfortable Housing Working Committee of the China Building Energy Conservation Association, and the Henan Provincial City Council.

On November 8, a delegation from Jiangsu Haodong Group visited our company to conduct learning and exchanges around SPD water-based foamed polyurea sound insulation panels and floor sound insulation and insulation systems.

Polyurethane rigid foam waterproof and thermal insulation integrated panels combine waterproof and thermal insulation functions and are widely used in building exterior walls, roofs and other scenarios. In order to extend its service life and maintain performance, scientific maintenance must be carried out in terms of daily cleaning, protection, inspection, repair, storage and transportation. The following are specific maintenance methods: 1. Daily cleaning and maintenance Clean the surface regularly and use a soft brush or vacuum cleaner to remove dust and debris on the board to avoid scratches with hard objects that may cause coating damage. For oil stains and stains, you can use neutral detergent (such as dishwashing liquid) mixed with warm water, wipe with a soft cloth and rinse with water. Do not use strong acids, alkalis or organic solvents (such as gasoline, Tianna water). To avoid long-term water accumulation, check whether the drainage system (such as roof gutters and exterior wall drains) is smooth to prevent accumulation of rainwater from causing soaking of boards and affecting the performance of the waterproof layer. 2. Protective measures to prevent ultraviolet aging. For boards that have been exposed to the sun for a long time, it is recommended to apply a layer of ultraviolet protective agent (such as polyurethane special paint) every 3-5 years.
