Recently, commissioned by the Global Isocyanate Association, China Polyurethane Industry Association Training Center held the third phase of polyurethane foam spraying EHSQ training course in Shaoxing, China-Chong Polyurethane Co. The equipment used in this training is a supercritical CO2 auxiliary high-pressure foaming equipment developed by Shaoxing Hua Chong.
The equipment can produce polyurethane foam ODS environment-friendly alternative products, has been unanimously affirmed by the field experts. According to Shaoxing Hua Chong General manager Siangminghua, the equipment technology developed by Nanjing Forestry University, in September 2016 to complete the supercritical CO2-assisted foam polyurethane spraying high-pressure foaming machine equipment development. This technology equipment for the first time CO2 metering and conveying device (one-way valve) combination, the optimization design of supercritical CO2 auxiliary full-blown foam spray formula, to solve the composition system viscosity, CO2 compatibility and other series of problems.
From March 2017 to date, has been in a number of construction sites, cold storage application implementation, access to users alike. As the academician of Chinese Academy of Engineering, Chen Jianfeng, vice president of Beijing Chemical Engineering University, the appraisal opinion issued by the Appraisal Committee shows that the project developed a new kind of rigid polyurethane foam spraying equipment system, screened and developed the Polyether component and optimized formula matching the equipment,
It realizes the application of supercritical CO2-assisted foam spraying rigid polyurethane foam in the field, the equipment belongs to the first set of domestic, the whole reaches the international advanced level, and recommends further speeding up the large-scale production of equipment and the popularization and application of domestic and foreign markets.
Siangminghua introduced that the equipment has low cost, good performance, easy to use and other characteristics, has been China invention Patent 4, utility model patent 5, 1 international PCT Patent and U.S. patent has been publicized, the establishment of enterprise standards 2. With the recent environmental protection departments to carry out the implementation of ODS special action, hcfc-141b, such as the price of blowing agents rose, Shaoxing Hua Chong's new polyurethane foam equipment market hot. Siangminghua estimates that the company can achieve sales revenue of 200 million yuan by annual production and sales of 1000 sets of meters.
