Introduction
On January 12th, the Expert Review Meeting for the Technical Specification for Lightweight Steel-faced Microporous Polycrystalline Composite Fire-resistant Air Ducts (hereinafter referred to as the Specification), a group standard of the Guangdong Construction Industry Association jointly edited by ABA New Materials Group and Guangzhou Installation Engineering Group, and co-compiled by Guangdong No.6 Construction Engineering Group, Guangzhou Construction Group, Guangzhou Construction Engineering Design Institute, China State Construction Eighth Engineering Division South China Construction Co., Ltd., Dongguan Construction Industry Association and other organizations, was successfully held at ABA Guangzhou Center and passed the review smoothly.
Representatives from the Guangdong Construction Industry Association, the review expert group, the chief editing units and the co-compiling units attended the meeting. The leaders and experts present included: Ji Guangyan, Deputy Director of the Quality and Technology Department of Guangdong Construction Industry Association; review experts Lin Xiong, Liu Pojun, Liu Xiaodong, Zhao Yanwen and Zhang Zhiyuan; He Weibin, Deputy General Manager and Chief Engineer of Guangzhou Installation Engineering Group, etc. Gu Xiao, Founder of ABA; Wu Baocheng, General Manager of Domestic Marketing Center; Huang Biao, Senior Director of Passive Fire Protection Product Technology Delivery Center, as well as the air duct technical team, participated in the whole process.
The approval of the Specification marks that ABA has taken a more solid step forward in promoting the standardization and popularization of fire-resistant air duct technologies.
1. Co-building Standards: Filling the Gap in Industry Technical Standards
This review meeting brought together the Guangdong Construction Industry Association and many authoritative experts in the industry. After listening to the compilation team's introduction to the background and main technical contents of the Specification, and conducting inquiries and discussions, the review experts unanimously agreed that:
The Specification features rigorous structure, advanced technology and strong applicability, with significant promotion value, and thus approved the review.
The formulation of the Specification aims to address the common challenges of traditional air ducts in fire resistance, energy conservation and installation, while providing a full-process technical basis from design, material selection, construction to acceptance for the innovative solution of "lightweight steel-faced microporous polycrystalline composite fire-resistant air ducts". As the core compiling unit of the Specification, ABA has deeply participated in the construction of the standard framework, verification of key technical indicators and integration of engineering practice cases, providing core technical support for the scientificity and operability of the Specification.
2. Innovation-driven: Core Technical Support Behind the Specification
The technical route of "lightweight steel-faced microporous polycrystalline composite" focused on in the Specification is the condensation of core technologies of ABA's integrated composite air duct system, and its technical advantages have been highly recognized by the expert group:
Comprehensive Compliance with Safety Performance Requirements
• Fire Rating: The independently developed ABA® Board is adopted, whose combustion performance meets the Grade A1 non-combustibility requirement specified in the national standard GB 8624-2012. Its fire resistance limit covers 0.5 to 3 hours, complying with the requirements of GB 51251-2017 Technical Standard for Building Smoke Control and Exhaust Systems and other specifications.
• Structural Safety: The integrated design integrates load-bearing, fire resistance and thermal insulation functions, eliminating the potential safety hazard of "easy delamination of multi-layer composites" in traditional air ducts.
Significant Improvement in Engineering Efficiency
• Lightweight Advantage: Compared with the traditional structure of "sheet metal + external fireproof layer", the weight is reduced by more than 50%, lowering the load on the building structure.
• Construction Innovation: The prefabricated dry construction technology improves on-site installation efficiency by 50%, greatly shortening the construction period, which is in line with the technical orientation of "convenient construction and controllable quality" emphasized in the Specification.
Whole-life Cycle Cost Optimization
• Durability and Reliability: It has excellent moisture-proof and corrosion-resistant performance, with a long designed service life and minimal maintenance throughout the whole life cycle.
• Energy Conservation and Consumption Reduction: The thermal conductivity coefficient is less than 0.16 W/(m·K), and the energy-saving index is better than the industry average, contributing to the construction of green buildings.
The smooth approval of the Specification is an important milestone for ABA to practice the concept of "innovative manufacturing for safety" and actively fulfill its industry responsibilities. In the future, ABA will continue to cooperate with outstanding partners in the industrial chain, and with more advanced technologies, more reliable products and more complete standard solutions, promote the evolution of building smoke control and exhaust systems towards a safer, more efficient and greener direction, injecting core driving force into the high-quality development of the construction industry.
