On April 26, the China Household Appliance Industry Chain Conference was grandly held in Shanghai. At the same time as the event, the Golden Spike Award, the most gold-rich technology award for upstream enterprises in China’s home appliance industry chain, was announced. Wanhua Chemical won the 2023 China Home Appliance Industry Chain Golden Spike Award for its 70-second ultra-fast de-low conductivity solution for home appliances.
In the production process of refrigerators, the molding process of polyurethane insulation layer is a key link that affects the insulation performance of products and the production efficiency of home appliance enterprises. Through a series of technological breakthroughs such as breakthroughs in the molecular structure of raw materials, development of compound catalysts, and improvement of system material formulations, Wanhua Chemical has formed an overall ultra-fast demoulding solution covering all production systems on the market.
Among them, the world’s first ultra-microporous quick-release system increases the demoulding time to 70 seconds under the premise of ensuring performance, which is 20 seconds faster than the previous world’s first level of 90 seconds. The multi-mixed foaming system increases the demoulding time of ordinary three-door refrigerators to 80 seconds, which is much higher than the industry average of 180 seconds. The demoulding time of side-by-side refrigerators has increased to 130 seconds, much higher than the industry average of 210 seconds. It has greatly improved the production efficiency of home appliance companies, saved energy consumption, and reduced the manufacturing cost of each refrigerator by 8%-10%, leading the transformation and upgrading of the home appliance industry. At the same time, this technology provides the industry with refrigerators and freezers with lower energy consumption, which can save 2% of the electricity consumption of each refrigerator, helping environmental protection and carbon reduction.
Facing the dual-carbon target, the global home appliance industry is undergoing new changes. On the one hand, the market demand for green and energy-saving products is becoming stronger and stronger. On the other hand, home appliance companies have an urgent need to transform and upgrade their overall competitiveness. Faced with the trend of lower energy consumption, differentiated design, green environmental protection requirements and global development in the home appliance industry, Wanhua Chemical focuses on the four directions of green environmental protection, performance improvement, comprehensive cost optimization and process upgrading in the direction of home appliance polyurethane insulation, and keeps on stream Empower the industry to transform and upgrade.
In terms of green environmental protection, through technologies such as bio-based products, recycled materials, and foam recycling, we will comprehensively promote the in-depth development of circular economy, and help downstream customers achieve green upgrades on the premise of ensuring performance indicators. In terms of performance improvement, polyurethane insulation materials with higher thermal insulation performance, smoother appearance and longer service life help downstream customers improve their competitive advantages. In order to further reduce the comprehensive cost of home appliance production, Wanhua Chemical has significantly improved production efficiency through the pioneering technology and product response system. At the same time, through friendly operability, the downstream process upgrade is continuously promoted.
